Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations FCB Financial Holdings, Inc. (the “Company”), formerly known as Bond Street Holdings, Inc., is a national bank holding company with one wholly-owned national bank subsidiary, Florida Community Bank, N.A. (“Florida Community Bank” or the “Bank”), headquartered in Weston, Florida, offering a comprehensive range of traditional banking products and services to individual and corporate customers through 49 banking centers located in Florida at December 31, 2015. Principles of Consolidation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank’s subsidiaries, which consist of a group of real estate holding companies. Intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The Company’s financial reporting and accounting policies conform to U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates subject to significant change include the allowance for loan losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, contingent consideration liabilities, acquisition-related fair value computations, stock-based compensation and deferred taxes. Business combinations The Company accounts for transactions that meet the definition of a purchase business combination by recording the assets acquired and liabilities assumed at their fair value upon acquisition. The operations of the acquisitions are included in the consolidated financial statements from the date of acquisition. Intangible assets, indemnification contracts and contingent consideration are identified and recognized individually. If the fair value of the assets acquired exceeds the purchase price plus the fair value of the liabilities assumed, a bargain purchase gain is recognized. Conversely, if the purchase price plus the fair value of the liabilities assumed exceeds the fair value of the assets acquired, goodwill is recognized. The Company’s assumptions utilized to determine the fair value of assets acquired and liabilities assumed conform to market conditions at the date of acquisition. The provisional amounts recorded are updated if better information is obtained about the initial assumptions used to determine fair value or if new information is obtained regarding the facts and circumstances that existed at the date of acquisition. The provisional amounts may be adjusted through the completion of the measurement period, which does not exceed one year from the date of acquisition. Fair Value Measurement The Company uses estimates of fair value in applying various accounting standards for its consolidated financial statements on either a recurring or non-recurring basis. Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between willing and able market participants. The Company groups its assets and liabilities measured at fair value in three hierarchy levels, based on the observability and transparency of the inputs. These levels are as follows: Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; Level 2—Observable inputs other than level 1 inputs, including quoted prices for similar assets and liabilities, quoted prices for identical assets and liabilities in less active markets and other inputs that can be corroborated by observable market data; Level 3—Unobservable inputs supported by limited or no market activity or data and inputs requiring significant management judgment or estimation; valuation techniques utilizing level 3 inputs include option pricing models, discounted cash flow models and similar techniques. It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs in estimating fair value. Unobservable inputs are utilized in determining fair value estimates only to the extent that observable inputs are not available. The need to use unobservable inputs generally results from a lack of market liquidity and trading volume. Transfers between levels of fair value hierarchy are recorded at the end of the reporting period. Accounting Standards Codification (“ASC”) Topic 825, Financial Instruments, allows the Company an irrevocable option for measurement of eligible financial assets or financial liabilities at fair value on an instrument by instrument basis (the fair value option). An election may be made at the time an eligible financial asset, financial liability or firm commitment is recognized or when certain specified reconsideration events occur. The Company has not elected the fair value option for any eligible financial instrument as of December 31, 2015 and 2014. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. A gain or loss is recognized in earnings upon completion of the sale based on the difference between the sales proceeds and the carrying value of the assets. Control over the transferred assets is deemed to have been surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, interest-bearing deposits with banks, Federal funds sold and securities purchased under resale agreements or similar arrangements. Cash and cash equivalents have original maturities of three months or less. Accordingly, the carrying amount of such instruments is considered a reasonable estimate of fair value. The Company’s balances maintained may at times exceed federal depository insurance limits. The Bank is required to maintain reserve balances with the FRB. Such reserve requirements are based on a percentage of deposit liabilities and may be satisfied by cash on hand. The reserve balance requirement was $25.0 million as of December 31, 2015. Investment Securities The Company determines the classification of investment securities at the time of purchase. If the Company has the intent and the ability at the time of purchase to hold debt securities until maturity, they are classified as held-to-maturity. Investment securities held-to-maturity are stated at amortized cost. Debt securities the Company does not intend to hold to maturity are classified as available for sale and carried at estimated fair value with unrealized gains or losses reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), net of applicable income taxes. Available for sale securities are a part of the Company’s asset/liability management strategy and may be sold in response to changes in interest rates, prepayment risk or other market factors. Interest income and dividends on securities are recognized in interest income on an accrual basis. Premiums and discounts on debt securities are amortized as an adjustment to interest income over the period to maturity of the related security using the effective interest method. Realized gains or losses on the sale of securities are determined using the specific identification method. The Company reviews investment securities for impairment on a quarterly basis or more frequently if events and circumstances warrant. In order to determine if a decline in fair value below amortized cost represents OTTI, management considers several factors, including but not limited to, the length of time and extent to which the fair value has been less than the amortized cost basis, the financial condition and near-term prospects of the issuer (considering factors such as adverse conditions specific to the issuer and the security and ratings agency actions) and the Company’s intent and ability to retain the investment in order to allow for an anticipated recovery in fair value. The Company recognizes OTTI of a debt security for which there has been a decline in fair value below amortized cost if (i) management intends to sell the security, (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, or (iii) the Company does not expect to recover the entire amortized cost basis of the security. The amount by which amortized cost exceeds the fair value of a debt security that is considered to have OTTI is separated into a component representing the credit loss, which is recognized in earnings, and a component related to all other factors, which is recognized in other comprehensive income (loss). The measurement of the credit loss component is equal to the difference between the debt security’s amortized cost basis and the present value of its expected future cash flows discounted at the security’s effective yield. If the Company intends to sell the security, or if it is more likely than not it will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the amortized cost basis and fair value of the security. The Bank, as a member of the FHLB is required to maintain an investment in the stock of the FHLB. No market exists for this stock, and the Bank’s investment can be liquidated only through redemption by the FHLB, at the discretion of and subject to conditions imposed by the FHLB. Historically, FHLB stock redemptions have been at cost (par value), which equals the Company’s carrying value. The Company monitors its investment in FHLB stock for impairment through review of recent financial results of the FHLB including capital adequacy and liquidity position, dividend payment history, redemption history and information from credit agencies. The Company has not identified any indicators of impairment of FHLB stock. Loans The Company’s accounting methods for loans differ depending on whether the loans are new (“New” loans) or acquired (“Acquired” loans), and for acquired loans, whether the loans were acquired at a discount as a result of credit deterioration since the date of origination. New Loans The Company accounts for originated loans and purchased loans not acquired through business acquisitions as new loans. New loans that management has the intent and ability to hold for the foreseeable future are reported at their outstanding principal balances net of any allowance for loan losses, unamortized deferred fees and costs and unamortized premiums or discounts. The net amount of nonrefundable loan origination fees and certain direct costs associated with the lending process are deferred and amortized to interest income over the contractual lives of the new loans using methods which approximate the level yield method. Discounts and premiums are amortized or accreted to interest income over the estimated term of the new loans using methods that approximate the level yield method. Interest income on new loans is accrued based on the unpaid principal balance outstanding and the contractual terms of the loan agreements. Acquired Loans Acquired loans are accounted for under ASC 310-30 unless the loan type is excluded from the scope of ASC 310-30 (i.e. loans where borrowers have revolving privileges at acquisition date, or “Non-ASC 310-30” loans). The Company has elected to account for loans acquired with deteriorated credit quality since origination under ASC 310-30 (“ASC 310-30” loans or pools) due to the following: • There is evidence of credit quality deterioration since origination resulting in a “Day 1” discount attributable, at least in part, to credit quality; • The loans were acquired in a business combination or asset purchase; and • The loans are not to be subsequently accounted for at fair value. The Company has elected this policy for loans acquired through business combinations exhibiting credit deterioration since origination, except those loan types which have been scoped out of ASC 310-30. Substantially all loans acquired through the FDIC-assisted acquisitions had a fair value discount at acquisition date due at least in part to deterioration in credit quality since origination. However, there was a separate grouping of loans individually identified with substantial credit impairment that would be explicitly scoped into ASC 310-30 from those that were classified by analogy. The Company determined that a loan would be explicitly scoped into ASC 310-30 if there was evidence of credit deterioration at Day 1 and that it was probable that the Company would be unable to collect all contractual cash flows receivable. The loans that were classified by analogy were determined to have evidence of credit deterioration at Day 1 and that it was possible, not probable, that the Company would be unable to collect all contractual cash flows receivable. For each acquisition, ASC 310-30 loans are aggregated into pools based on common risk characteristics, which includes similar credit risk of the loans based on whether loans were analogized or were explicitly scoped into ASC 310-30, internal risk ratings for commercial real estate, land and development and commercial loans; and performing status for consumer and single family residential loans. Pools of loans are further aggregated by collateral type (e.g. commercial real estate, single family residential, etc.). The Company did not elect to aggregate loans into pools that were acquired from separate acquisitions completed in the same fiscal quarter. Acquired loans are recorded at their fair value at the acquisition date. Fair value for acquired loans is based on a discounted cash flow methodology that considers factors including the type of loan and related collateral type, delinquency and credit classification status, fixed or variable interest rate, term of loan, whether or not the loan was amortizing, and current discount rates. Additional assumptions used include default rates, loss severity, loss curves and prepayment speeds. Discounts due to credit quality are included in the determination of fair value; therefore an allowance for loan losses is not recorded at the acquisition date. The discount rates used for the cash flow methodology are based on market rates for new originations of comparable loans at the time of acquisition and include adjustments for liquidity concerns. The fair value is determined from the discounted cash flows for each individual loan, and for ASC 310-30 loans are then aggregated at the unit of account, or pool level. For acquired loans with deteriorated credit quality, the Company makes an estimate of the total cash flows it expects to collect from the loans in each pool, which includes undiscounted expected principal and interest as well as cash received through other forms of satisfaction (e.g. foreclosure). The excess of contractual amounts over the total cash flows expected to be collected from the loans is referred to as non-accretable difference, which is not accreted into income. The excess of the expected undiscounted cash flows over the carrying value of the loans is referred to as accretable discount. Accretable discount is recognized as interest income on a level-yield basis over the expected term of the loans in each pool. The Company continues to estimate cash flows expected to be collected over the expected term of the ASC 310-30 loans on a quarterly basis. Subsequent increases in total cash flows expected to be collected are recognized as an adjustment to the accretable discount with the amount of periodic accretion adjusted over the remaining expected term of the loans. Subsequent decreases in cash flows expected to be collected over the expected term of the loans are recognized as impairment in the current period through a provision for loan losses. Each pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. Resolutions of loans may include sales to third parties, receipt of payments in settlement with the borrower, or foreclosure of the collateral. Upon these resolutions, the Company’s policy is to remove an individual ASC 310-30 loan from a pool based on comparing the amount received from its resolution with its contractual amount. Any difference between these amounts is absorbed by the nonaccretable difference. This removal method assumes that the amount received from these resolutions approximates the pool performance expectations of cash flows. The accretable yield percentage is unaffected by the resolution. Any changes in the effective yield for the remaining loans in the pool are addressed by the quarterly cash flow evaluation process for each pool. For loans that are resolved by payment in full, there is no release of the nonaccretable difference for the pool because there is no difference between the amount received at resolution and the contractual amount of the loan. Payments received in excess of expected cash flows may result in an ASC 310-30 pool becoming fully amortized and its carrying value reduced to zero even though outstanding contractual balances remain related to loans in the pool. Once the carrying value of an ASC 310-30 pool is reduced to zero, any future proceeds from the borrower or from the sale of loans are recognized as interest income upon receipt. There were nine ASC 310-30 pools whose carrying value had been reduced to zero as of December 31, 2015. These pools had an aggregate Unpaid Principal Balance (“UPB” or “UPBs”) of $4.5 million as of December 31, 2015. For the year ended December 31, 2015, the Company sold approximately $55.1 million of loans accounted for under ASC 310-30. These sales resulted in proceeds that exceeded the carrying value of the accounting pool in which the loans resided of $11.5 million which was recognized as interest income. Non-ASC 310-30 loans are recorded at their estimated fair value as of the acquisition date and subsequently accounted for under ASC Topic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASC 310-20”). The fair value discount is accreted using methods which approximate the level-yield method over the remaining term of the loans and is recognized as a component of interest income. Loans Held for Sale Certain residential fixed rate and adjustable rate mortgage loans originated by the Company with the intent to sell in the secondary market are carried at the lower of cost or fair value, as determined by outstanding commitments from investors. These loans are generally sold on a non-recourse basis with servicing released. Gains and losses on the sale of loans recognized in earnings are measured based on the difference between proceeds received and the carrying amount of the loans, inclusive of deferred origination fees and costs, if any. Nonaccrual Loans For new and Non-ASC 310-30 loans, the Company classifies loans as past due when the payment of principal or interest is greater than 30 days delinquent based on the contractual next payment due date. The Company’s policies related to when loans are placed on nonaccrual status conform to guidelines prescribed by regulatory authorities. 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. Loans secured by one to four family residential properties may remain in accruing status until they are 180 days past due if management determines that it does not have concern over the collectability of principal and interest because the loan is adequately collateralized and in the process of collection. When loans are placed on nonaccrual status, interest receivable is reversed against interest income in the current period and amortization of any discount ceases. Interest payments received thereafter are applied as a reduction to the remaining principal balance unless management believes that the ultimate collection of the principal is likely, in which case payments are recognized in earnings on a cash basis. Loans are removed from nonaccrual status when they become current as to both principal and interest and the collectability of principal and interest is no longer doubtful. Generally, a nonaccrual loan that is restructured remains on nonaccrual for a period of six months to demonstrate the borrower can meet the restructured terms. However, performance prior to the restructuring, or significant events that coincide with the restructuring, are considered in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan remains classified as a nonaccrual loan. Contractually delinquent ASC 310-30 loans are not classified as nonaccrual as long as the discount continues to be accreted on the corresponding ASC 310-30 pool. Troubled Debt Restructurings In certain situations due to economic or legal reasons related to a borrower’s financial difficulties, the Company may grant a concession to the borrower for other than an insignificant period of time that it would not otherwise consider. At that time, except for ASC 310-30 loans, which are accounted for as pools, the related loan is classified as a troubled debt restructuring (“TDR”) and considered impaired. Modified ASC 310-30 loans accounted for in pools are not accounted for as TDRs, are not separated from the pools and are not classified as impaired loans. The concessions granted may include rate reductions, principal forgiveness, payment forbearance, extensions of maturity at rates of interest below those commensurate with the risk profile of the borrower, and other actions intended to minimize economic loss. A troubled debt restructured loan is generally placed on nonaccrual status at the time of the modification unless the borrower has no history of missed payments for six months prior to the restructuring. If the borrower performs pursuant to the modified loan terms for at least six months and the remaining loan balance is considered collectible, the loan is returned to accrual status. Impaired Loans An ASC 310-30 pool is considered to be impaired when it is probable that the Company will be unable to collect all the cash flows expected at acquisition, plus additional cash flows expected to be collected arising from changes in estimates after acquisition. All ASC 310-30 pools are evaluated individually for impairment based their expected total cash flows. The discount continues to be accreted on ASC 310-30 pools as long as there are expected future cash flows in excess of the current carrying amount of the pool. Non-ASC 310-30 and new loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. All Non-ASC 310-30 and new loans of $250,000 or greater with an internal risk rating of substandard or below and on nonaccrual, as well as loans classified as TDRs are reviewed individually for impairment on a quarterly basis. Allowance for Loan Losses The Company’s ALL is established for both performing and nonperforming loans. The Company’s ALL is the amount considered adequate to absorb probable losses within the portfolio based on management’s evaluation of the size and current risk characteristics of the loan portfolio. Such evaluation considers numerous factors including, but not limited to, internal risk ratings, loss forecasts, collateral values, geographic location, borrower FICO scores, delinquency rates, nonperforming and restructured loans, origination channels, product mix, underwriting practices, industry conditions, economic trends and net charge-off trends. The ALL relates to new loans, estimated additional losses arising on Non-ASC 310-30 loans subsequent to the acquisitions and additional impairment recognized as a result of decreases in expected cash flows on ASC 310-30 pools due to further credit deterioration or other factors since the acquisitions. The ALL consists of both specific and general components. For ASC 310-30 pools, a specific valuation allowance is established when it is probable that the Company will be unable to collect all of the cash flows expected at acquisition, plus the additional cash flows expected to be collected arising from changes in estimates after acquisition. Expected cash flows are estimated on an individual loan basis and then aggregated at the ASC 310-30 pool level. The analysis of expected pool cash flows incorporates updated pool level expected prepayment rate, default rate, delinquency level and loss severity given default assumptions. These analyses incorporate information about loan performance, collateral values, the financial condition of the borrower, internal risk ratings, the Company’s own and industry historical delinquency and default severity data. The carrying value for ASC 310-30 pools is reduced by the amount of the calculated impairment, which is also the basis in which future accretion income is calculated. A charge-off is taken for an individual ASC 310-30 loan when it is deemed probable that the loan will be resolved for an amount less than its carrying value. The charge-off is taken to the specific allowance or mark as applicable. Alternatively, an improvement in the expected cash flows related to ASC 310-30 pools results in a reduction or recoupment of any previously established specific allowance with a corresponding credit to the provision for loan losses. Any recoupment recorded is limited to the amount of the remaining specific allowance for that pool, with any excess of expected cash flow resulting in a reclassification from non-accretable to accretable yield and an increase in the prospective yield of the pool. The new and Non-ASC 310-30 loan portfolios have limited delinquency and credit loss history and have not yet exhibited an observable loss trend. The credit quality of loans in these loan portfolios are impacted by delinquency status and debt service coverage generated by the borrowers’ businesses and fluctuations in the value of real estate collateral. Management considers delinquency status to be the most meaningful indicator of the credit quality of one-to-four single family residential, home equity loans and lines of credit and other consumer loans. Delinquency statistics are updated at least monthly. Internal risk ratings are considered the most meaningful indicator of credit quality for Non ASC 310-30 and new commercial, construction, land and development, and commercial real estate loans. Internal risk ratings are a key factor in identifying loans that are individually evaluated for impairment and impact management’s estimates of loss factors used in determining the amount of the ALL. Internal risk ratings are updated on a continuous basis. Relationships with balances in excess of $250,000 are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. New and Non-ASC 310-30 loans of $250,000 or greater with an internal risk rating of substandard or below and on nonaccrual, as well as loans classified as TDR are reviewed individually for impairment on a quarterly basis. The specific allowance established for these loans is based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated market value or the estimated fair value of the underlying collateral less costs of disposition. General allowances are established for new and Non-ASC 310-30 loans that are not evaluated individually for impairment, which are evaluated by loan category based on common risk characteristics. In this process, general loan loss factors are established based on the following: historical loss factors derived from the Federal Financial Institutions Examination Council’s quarterly Unified Performance Branch Report for Group 1 banks (assets greater than $3 billion) using an annualized weighted average eight quarter rolling basis; trends in delinquencies and nonaccruals by loan portfolio segment and asset categories within those segments; portfolio segment and asset category production trends, including average risk ratings and loan-to value (“LTV”) ratios; current industry conditions, including real estate market trends; general economic conditions; credit concentrations by portfolio and asset categories; and portfolio quality, which encompasses an assessment of the quality and relevance of borrowers’ financial information and collateral valuations and average risk rating and migration trends within portfolios and asset categories. Other adjustments for qualitative factors may be made to the allowance after an assessment of internal and external influences on credit quality and loss severity that are not fully reflected in the historical loss or risk rating data. For these measurements, the Company uses assumptions and methodologies that are relevant to estimating the level of impairment and probable losses in the loan portfolio. To the extent that the data supporting such assumptions has limitations, management’s judgment and experience play a key role in recording the allowance estimates. Qualitative adjustments are considered for: portfolio credit quality trends, including levels of delinquency, charge-offs, nonaccrual, restructuring and other factors; policy and credit standards, including quality and experience of lending and credit management; and general economic factors, including national, regional and local conditions and trends. Additions to the ALL are made by provisions charged to earnings. The allowance is decreased by charge-offs of balances no longer deemed collectible. Charge-offs on new and Non-ASC 310-30 loans are recognized as follows: commercial loans are written-off when management determines them to be uncollectible; for unsecured consumer loans at 90 days past due; and for residential real estate loans and secured consumer loans when they become 120 to 180 days past due, depending on the collateral type. The Company reports recoveries on a cash basis at the time received. Recoveries on ASC 310-30 loans that were charged-off and Non-ASC 310-30 loans that were charged-off prior to the Acquisitions are recognized in earnings as income from resolution of acquired assets and do not affect the allowance for loan losses. All other recoveries are credited to the ALL. Loss Share Indemnification Asset and Clawback Liability Assets subject to loss sharing agreements with the FDIC are labeled “Covered Assets” in the consolidated financial statements and include acquired loans (“Covered Loans”) and OREO. The loss share indemnification asset is measured separately from the Covered Assets acquired as it is not contractually embedded in any of the Covered Assets. The initial fair value of the loss share indemnification asset represents the present value of the estimated cash payments expected to be received from the FDIC for future losses on Covered Assets, based on the credit adjustment estimated for each Covered Asset and the loss sharing percentages. The estimated cash flows are discounted using a risk-free yield curve plus a premium reflecting the uncertainty related to the timing and receipt of such cash flows. The amount ultimately collected for this asset is dependent upon the performance of the underlying Covered Assets, the passage of time and claims submitted to the FDIC. The amounts covered by the loss sharing agreements are the pre-acquisition book value of the underlying assets, the contractual balance of unfunded commitments that were acquired, and certain future net di

Business Combinations [Abstract]
Business Acquisitions	NOTE 2. BUSINESS ACQUISITIONS On January 31, 2014, the Bank acquired all the outstanding common stock in GFB. GFB had total assets of $957.3 million and total liabilities of $962.2 million at fair value as of January 31, 2014. Holders of GFB common stock received $3.24 per share in cash for each common share owned resulting in total cash purchase price of $42.5 million. At the time of acquisition, GFB had 25 banking locations within Southeast Florida and the Miami metropolitan area. The Company contributed capital of $125 million to the Bank at the time of the GFB acquisition. The Company determined that the acquisition of Great Florida Bank constitutes a business combination as defined by the FASB ASC topic 805, “Business Combinations”. Accordingly, the assets acquired and liabilities assumed were recorded at their fair values on the date of acquisition. Fair values were determined in accordance with the guidance provided in FASB ASC Topic 820, “Fair Value Measurements”. In many cases the determination of the fair values required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change. The Company utilized the assistance of third-party advisors in the determination of fair values for loans, other real estate owned and deferred tax assets acquired. The following table presents a summary of the assets acquired and liabilities assumed in the Great Florida Bank acquisition recorded at fair value. (Dollars in thousands) Consideration paid: Cash $ 42,485 Fair value of assets acquired: Cash and cash equivalents 28,412 Investment securities 277,639 Loans 548,129 Other real estate owned 55,085 Core deposit intangible 3,601 Fixed assets 2,576 Deferred tax asset, net 35,736 Other assets 6,146 Total identifiable assets acquired 957,324 Fair value of liabilities assumed: Deposits 863,976 FHLB advances and other borrowings 92,669 Other liabilities 5,549 Total liabilities assumed 962,194 Fair value of net assets acquired (4,870 ) Goodwill resulting from acquisition $ 47,355 The following is a description of the methods used to determine the fair values of significant assets and liabilities presented above: Cash and Cash Equivalents: These assets are carried at amounts that approximate fair value due to their short-term nature and generally negligible credit risk. Investment Securities: Fair value measurement is based upon quoted market prices for similar securities in active or inactive markets (Level 2). FHLB and other bank stock are carried at par, which has historically represented the redemption price and is therefore considered to approximate fair value. Loans: Acquired loans are recorded at their fair value at the date of acquisition. Fair value for acquired loans is based on a discounted cash flow methodology that considers factors including the type of loan and related collateral type, delinquency and credit classification status, fixed or variable interest rate, term of loan, whether or not the loan was amortizing, and current discount rates. Additional assumptions used include default rates, loss severity, loss curves and prepayment speeds. Discounts due to credit quality are included in the determination of fair value; therefore an allowance for loan losses is not recorded at the acquisition date. The discount rates used for the cash flow methodology are based on market rates for new originations of comparable loans at the time of acquisition and include adjustments for liquidity concerns. The fair value is determined from the discounted cash flows for each individual loan, and for ASC 310-30 loans are then aggregated at the unit of account, or pool level. The following is a summary of the acquired loans accounted for under ASC 310-30 as well as those excluded from ASC 310-30, or Non-ASC 310-30 acquired loans, in connection with the acquisition of Great Florida Bank: (Dollars in thousands) Acquired loans accounted for under ASC 310-30: Contractual cash flows $ 426,116 Contractual cash flows not expected to be collected (non-accretable difference) 102,581 Expected cash flows 323,535 Excess of the expected undiscounted cash flows over the carrying value (accretable discount) 40,444 Fair value at acquisition $ 283,091 Acquired loans not accounted for under ASC 310-30 (Non-ASC 310-30 loans): Unpaid principal balance $ 275,772 Fair value discount (10,734 ) Fair value at acquisition 265,038 Total fair value at acquisition $ 548,129 The Company acquired loans with a fair value of $265.0 million that are classified as Non-ASC 310-30 loans as these specific loans did not exhibit deteriorated credit quality since origination or were loans to borrowers that had revolving privileges at acquisition date. The acquired Non-ASC 310-30 loans with revolving privileges had a total unpaid principal balance of $71.5 million and a fair value of $60.6 million at acquisition. The acquired Non-ASC 310-30 loans without revolving privileges had a total unpaid principal balance of $204.3 million and a fair value of $204.4 million at acquisition. OREO: The fair value of acquired OREO is based on the fair value of the property, less estimated cost to sell. Fair value of OREO is typically based on third party real estate appraisals which utilize market and income valuation techniques. Deferred Tax Asset: Deferred tax assets represent acquired loss and credit carryforwards and the net tax-affected differences between the book basis and tax basis of certain assets and liabilities, including investment securities, loans, OREO, fixed assets, core deposit intangible assets, time deposits, FHLB advances and other borrowings. The deferred tax assets are evaluated for certain carryover limitations at the acquisition date, such as Section 382 limitations, and whether it is more likely than not that the benefit from certain net operating loss carryforwards can be realized. As part of the acquisition of Great Florida Bank, the Bank recorded $35.7 million in deferred tax assets, net of $9.1 million in valuation allowance, at acquisition. Upon acquisition, Great Florida Bank incurred a Section 382 ownership change. As such, the Company’s ability to benefit from the use of Great Florida Bank’s pre-ownership change net operating loss and tax credit carry forwards, as well as the potential deductibility of certain of its built-in losses, will be limited to approximately $1.5 million per year, putting at risk the utilization of associated deferred tax assets before they expire. At the time of acquisition, the Company determined that it is more likely than not that the benefit from certain net operating loss carryforwards will not be realized. In recognition of this risk, a valuation allowance of $9.1 million was established against the deferred tax assets associated with Great Florida Bank’s pre-ownership change net operating loss carryforwards. As of December 31, 2015, Management believes the Company will realize the benefits from certain federal and state net operating loss carryforwards and as such has reversed the valuation allowance of $9.1 million previously provided on the deferred tax assets for federal and state net operating loss carryforwards. The reversal of the valuation allowance on the deferred tax assets was recognized as a reduction of income tax expense. Deposits: The fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the acquisition date. The fair value of fixed-maturity certificates of deposit is estimated using discounted cash flow analysis and using the rates currently offered for deposits of similar remaining maturities. Advances from the FHLB and Other Borrowings: The fair value of advances from the FHLB and other borrowings are estimated by discounting the future cash flows using the current rate at which similar borrowings with similar remaining maturities could be obtained. The Great Florida Bank acquisition resulted in goodwill of $47.4 million as the estimated fair value of liabilities assumed and consideration paid exceeded the estimated fair value of assets acquired. None of the goodwill resulting from the Great Florida Bank acquisition is deductible for tax purposes. The core deposit intangible is being amortized on straight line basis over the estimated life, currently expected to be 10 years. For the year ended December 31, 2014, the Company incurred $5.0 million of bank acquisition, legal fees, accounting advisory, data conversion, retention payments and severance expenses related to the acquisition of Great Florida Bank which is recorded in noninterest expenses in the consolidated statement of income.

A total of 168 were in an unrealized loss position for less than 12 months. The unrealized losses for these securities resulted primarily from changes in interest rates. The Company monitors its investment securities for OTTI. Impairment is evaluated on an individual security basis considering numerous factors, and its relative significance varying by situation. The Company has evaluated the nature of unrealized losses in the investment securities portfolio to determine if OTTI exists. The unrealized losses relate to changes in market interest rates and specific market conditions that do not represent credit-related impairments. Furthermore, the Company does not intend to sell nor is it more likely than not that it will be required to sell these investments before the recovery of their amortized cost basis. Management has completed an assessment of each security in an unrealized loss position for credit impairment, including securities with existing characteristics that are covered under the Volcker Rule, and has determined that no individual security was other-than-temporarily impaired at December 31, 2015 or 2014. The following describes the basis under which the Company has evaluated OTTI: U.S. Government Agencies and Sponsored Enterprises Obligations and Agency Mortgage-Backed Securities (“MBS”): The unrealized losses associated with U.S. Government agencies and sponsored enterprises obligations and agency MBS are primarily driven by changes in interest rates. These securities have either an explicit or implicit U.S. government guarantee. Asset-Backed Securities and Corporate Bonds & Other Debt Securities: Securities were generally underwritten in accordance with the Company’s investment standards prior to the decision to purchase, without relying on a bond issuer’s guarantee in making the investment decision. These investments are investment grade and will continue to be monitored as part of the Company’s ongoing impairment analysis, but are expected to perform in accordance with their terms. Preferred Stock and Other Equity Securities: The unrealized losses associated with preferred stock and other equity securities in large U.S. financial institutions are primarily driven by changes in interest rates. These securities were generally underwritten in accordance with the Company’s investment standards prior to the decision to purchase. These investments are investment grade and will continue to be monitored as part of the Company’s ongoing impairment analysis, but are expected to perform in accordance with their terms. Gross realized gains and losses on the sale of securities available for sale are shown below. The cost of securities sold is based on the specific identification method.

Loans, Net	NOTE 4. LOANS, NET The Company’s loan portfolio consists of new and acquired loans. The Company classifies originated loans and purchased loans not acquired through business combinations as New loans. The Company classifies loans acquired through business combinations as Acquired loans. The acquired loan portfolio is further classified as “Covered Loans”, loans subject to loss sharing with the FDIC, and “Non-Covered Loans”, acquired loans without loss share reimbursement. Additionally, the New loan portfolio is classified as “Non-Covered Loans”. A portion of the acquired loan portfolio, both Covered and Non-Covered Loans, exhibited evidence of deterioration in credit quality since origination, and are accounted for under ASC 310-30. The remaining portfolio of acquired loans consists of loans that were not considered ASC 310-30 loans at acquisition and are classified as Non-ASC 310-30 loans. On March 4, 2015, the Bank entered into an agreement with the FDIC to terminate all loss sharing agreements which were entered into in 2010 and 2011 in conjunction with the Bank’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of six failed banks in FDIC-assisted acquisitions. Under the early termination, all rights and obligations of the Bank and the FDIC under the loss share agreements, including the clawback provisions, have been eliminated. The following tables summarize the Company’s loans by portfolio and segment as of the periods presented, net of deferred fees, costs, premiums and discounts: Covered Loans Non-Covered Loans December 31, 2015 ASC Non-ASC 310-30 ASC 310-30 Non-ASC New Total (Dollars in thousands) Real estate loans: Commercial real estate $ — $ — $ 247,628 $ 55,985 $ 998,141 $ 1,301,754 Owner-occupied commercial real estate — — — 21,101 524,728 545,829 1-4 single family residential — — 40,922 84,111 1,541,255 1,666,288 Construction, land and development — — 28,017 6,338 537,494 571,849 Home equity loans and lines of credit — — — 49,407 30,945 80,352 Total real estate loans $ — $ — $ 316,567 $ 216,942 $ 3,632,563 $ 4,166,072 Other loans: Commercial and industrial $ — $ — $ 36,783 $ 9,312 $ 972,803 $ 1,018,898 Consumer — — 2,390 430 5,397 8,217 Total other loans — — 39,173 9,742 978,200 1,027,115 Total loans held in portfolio $ — $ — $ 355,740 $ 226,684 $ 4,610,763 $ 5,193,187 Allowance for loan losses (29,126 ) Loans held in portfolio, net $ 5,164,061 Covered Loans Non-Covered Loans December 31, 2014 ASC Non-ASC ASC Non-ASC New Total (Dollars in thousands) Real estate loans: Commercial real estate $ 155,050 $ 6,202 $ 181,885 $ 63,944 $ 853,074 $ 1,260,155 Owner-occupied commercial real estate — 2,411 — 12,431 281,703 296,545 1-4 single family residential 34,297 7,286 52,011 94,993 922,657 1,111,244 Construction, land and development 19,903 — 46,797 9,729 232,601 309,030 Home equity loans and lines of credit — 10,785 — 43,919 11,826 66,530 Total real estate loans $ 209,250 $ 26,684 $ 280,693 $ 225,016 $ 2,301,861 $ 3,043,504 Other loans: Commercial and industrial $ 32,531 $ 4,308 $ 34,967 $ 9,240 $ 795,000 $ 876,046 Consumer 557 36 2,246 645 6,556 10,040 Total other loans 33,088 4,344 37,213 9,885 801,556 886,086 Total loans held in portfolio $ 242,338 $ 31,028 $ 317,906 $ 234,901 $ 3,103,417 $ 3,929,590 Allowance for loan losses (22,880 ) Loans held in portfolio, net $ 3,906,710 (1) Balance includes $7.1 million and $3.6 million of deferred fees, costs, and premium and discount as of December 31, 2015 and December 31, 2014, respectively. At December 31, 2015 and 2014, the UPB of ASC 310-30 loans were $457.9 million and $725.9 million, respectively. At December 31, 2015 and 2014, the Company had pledged loans as collateral for FHLB advances of $2.13 billion and $1.63 billion, respectively. The recorded investments of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process as of December 31, 2015 totaled $5.7 million. The Company held $464.2 million and $445.6 million of syndicated national loans as of December 31, 2015 and 2014, respectively. During the years ended December 31, 2015, 2014 and 2013 the Company purchased approximately $379.3 million, $377.1 million and $187.4 million in loans from third parties. During the years ended December 31, 2015, 2014 and 2013, the Company sold approximately $91.8 million, $39.3 million and $47.3 million, respectively in loans to third parties. The accretable discount on ASC 310-30 loans represents the amount by which the undiscounted expected cash flows on such loans exceed their carrying value. The increase in expected cash flow for certain ASC 310-30 loan pools resulted in the reclassification of $43.0 million, $28.5 million and $34.8 million in non-accretable difference to accretable discount during the years ended December 31, 2015, 2014 and 2013, respectively. Changes in accretable discount for ASC 310-30 loans for the years ended December 31, 2015, 2014, and 2013 were as follows: Years Ended December 31, 2015 2014 2013 (Dollars in thousands) Balance at January 1, $ 156,197 $ 148,501 $ 175,873 Additions to accretable discount from GFB acquisition — 40,444 — Accretion (55,019 ) (61,281 ) (62,162 ) Reclassifications from non-accretable difference 42,974 28,533 34,790 Balance at December 31, $ 144,152 $ 156,197 $ 148,501

Allowance for Loan Losses	NOTE 5. ALLOWANCE FOR LOAN LOSSES The Company’s accounting method for loans and the corresponding ALL differs depending on whether the loans are New or Acquired. The Company assesses and monitors credit risk and portfolio performance using distinct methodologies for Acquired loans, both ASC 310-30 loans and Non-ASC 310-30 loans, and New loans. Within each of these portfolios, the Company further disaggregates the portfolios into the following segments: Commercial real estate, Owner-occupied commercial real estate, 1-4 single family residential, Construction, land and development, Home equity loans and lines of credit, Commercial and industrial and Consumer. The ALL reflects management’s estimate of probable credit losses inherent in each of the segments. Changes in the ALL by loan portfolio and segment for the years ended December 31, 2015, 2014 and 2013 are as follows: Commercial Owner- 1- 4 Single Construction, Home Commercial Consumer Total (Dollars in thousands) Balance at January 1, 2015 $ 8,206 $ 1,020 $ 4,740 $ 2,456 $ 355 $ 5,745 $ 358 $ 22,880 Provision (credit) for ASC 310-30 loans (1,487 ) — (37 ) (681 ) — (39 ) 175 (2,069 ) Provision (credit) for non-ASC 310-30 loans 589 405 46 (39 ) 138 11 6 1,156 Provision (credit) for New loans 1,012 818 2,066 1,317 122 2,417 (16 ) 7,736 Total provision 114 1,223 2,075 597 260 2,389 165 6,823 Charge-offs for ASC 310-30 loans (270 ) — (436 ) (56 ) — (643 ) (60 ) (1,465 ) Charge-offs for non-ASC 310-30 loans — — (128 ) — (132 ) — (8 ) (268 ) Charge-offs for New loans — — — — — (15 ) — (15 ) Total charge-offs (270 ) — (564 ) (56 ) (132 ) (658 ) (68 ) (1,748 ) Recoveries for ASC 310-30 loans 400 — 174 407 — 177 1 1,159 Recoveries for non-ASC 310-30 loans — — — — — — — — Recoveries for New loans — — — — — 12 — 12 Total recoveries 400 — 174 407 — 189 1 1,171 Ending ALL balance ASC 310-30 loans 1,898 — 26 328 — 453 406 3,111 Non-ASC 310-30 loans 1,084 463 332 36 291 60 4 2,270 New loans 5,468 1,780 6,067 3,040 192 7,152 46 23,745 Balance at December 31, 2015 $ 8,450 $ 2,243 $ 6,425 $ 3,404 $ 483 $ 7,665 $ 456 $ 29,126 Commercial Owner- 1- 4 Single Construction, Home Commercial Consumer Total (Dollars in thousands) Balance at January 1, 2014 $ 4,458 $ 376 $ 1,443 $ 1,819 $ 265 $ 6,198 $ 174 $ 14,733 Provision (credit) for ASC 310-30 loans 735 — 271 107 — (716 ) 245 642 Provision (credit) for non-ASC 310-30 loans 490 53 362 75 442 67 35 1,524 Provision (credit) for New loans 2,678 591 2,695 895 (56 ) 1,229 45 8,077 Total provision 3,903 644 3,328 1,077 386 580 325 10,243 Charge-offs for ASC 310-30 loans (270 ) — (31 ) (1,244 ) — (678 ) (113 ) (2,336 ) Charge-offs for non-ASC 310-30 loans — — — — (296 ) (24 ) (29 ) (349 ) Charge-offs for New loans — — — (6 ) — (348 ) — (354 ) Total charge-offs (270 ) — (31 ) (1,250 ) (296 ) (1,050 ) (142 ) (3,039 ) Recoveries for ASC 310-30 loans 115 — — 810 — 13 1 939 Recoveries for non-ASC 310-30 loans — — — — — — — — Recoveries for New loans — — — — — 4 — 4 Total recoveries 115 — — 810 — 17 1 943 Ending ALL balance ASC 310-30 loans 3,255 — 325 658 — 958 290 5,486 Non-ASC 310-30 loans 495 58 414 75 285 49 6 1,382 New loans 4,456 962 4,001 1,723 70 4,738 62 16,012 Balance at December 31, 2014 $ 8,206 $ 1,020 $ 4,740 $ 2,456 $ 355 $ 5,745 $ 358 $ 22,880 Commercial Owner- 1- 4 Single Construction, Home Commercial Consumer Total (Dollars in thousands) Balance at January 1, 2013 $ 3,734 $ 373 $ 3,049 $ 5,239 $ 67 $ 6,054 $ 433 $ 18,949 Provision (credit) for ASC 310-30 loans 1,263 — (1,558 ) 601 — (1,493 ) 510 (677 ) Provision (credit) for non-ASC 310-30 loans (3 ) (7 ) 30 (3 ) 415 (130 ) (4 ) 298 Provision (credit) for New loans 541 10 684 (141 ) 122 2,120 (43 ) 3,293 Total provision 1,801 3 (844 ) 457 537 497 463 2,914 Charge-offs for ASC 310-30 loans (1,387 ) — (830 ) (4,052 ) — (201 ) (723 ) (7,193 ) Charge-offs for non-ASC 310-30 loans — — — — (339 ) (163 ) — (502 ) Charge-offs for New loans — — — (193 ) — — — (193 ) Total charge-offs (1,387 ) — (830 ) (4,245 ) (339 ) (364 ) (723 ) (7,888 ) Recoveries for ASC 310-30 loans 310 — 68 368 — 11 1 758 Recoveries for non-ASC 310-30 loans — — — — — — — — Recoveries for New loans — — — — — — — — Total recoveries 310 — 68 368 — 11 1 758 Ending ALL balance ASC 310-30 loans 2,675 — 85 985 — 2,339 157 6,241 Non-ASC 310-30 loans 5 5 52 — 139 6 — 207 New loans 1,778 371 1,306 834 126 3,853 17 8,285 Balance at December 31, 2013 $ 4,458 $ 376 $ 1,443 $ 1,819 $ 265 $ 6,198 $ 174 $ 14,733 Credit Quality Indicators In evaluating credit risk, the Company looks at multiple factors; however, management considers delinquency status to be the most meaningful indicator of the credit quality of 1-4 single family residential, home equity loans and lines of credit and consumer loans. Delinquency statistics are updated at least monthly. Internal risk ratings are considered the most meaningful indicator of credit quality for Non-ASC 310-30 and New commercial, construction, land and development and commercial real estate loans. Internal risk ratings are updated on a continuous basis. The following tables present an aging analysis of the recorded investment for delinquent loans by portfolio and segment (excluding loans accounted for under ASC 310-30): Accruing December 31, 2015 30 to 59 60 to 89 90 Days or Non- Accrual Total (Dollars in thousands) New loans: Real estate loans: Commercial real estate $ — $ — $ — $ — $ — Owner-occupied commercial real estate — 113 — — 113 1-4 single family residential 9,439 869 — 1,454 11,762 Construction, land and development 467 — — — 467 Home equity loans and lines of credit 64 — — — 64 Total real estate loans 9,970 982 — 1,454 12,406 Other loans: Commercial and industrial $ — $ — $ — $ — $ — Consumer — — — — — Total other loans — — — — — Total new loans $ 9,970 $ 982 $ — $ 1,454 $ 12,406 Acquired loans: Real estate loans: Commercial real estate $ 63 $ — $ — $ 5,282 $ 5,345 Owner-occupied commercial real estate — 95 — 2,247 2,342 1-4 single family residential 1,393 697 — 3,016 5,106 Construction, land and development — — — — — Home equity loans and lines of credit 490 97 — 2,295 2,882 Total real estate loans 1,946 889 — 12,840 15,675 Other loans: Commercial and industrial $ 90 $ — $ — $ 877 $ 967 Consumer — — — 23 23 Total other loans 90 — — 900 990 Total acquired loans $ 2,036 $ 889 $ — $ 13,740 $ 16,665 Accruing December 31, 2014 30 to 59 60 to 89 90 Days or Non-Accrual Total (Dollars in thousands) New loans: Real estate loans: Commercial real estate $ — $ — $ — $ — $ — Owner-occupied commercial real estate — — — — — 1-4 single family residential 6,206 727 — 116 7,049 Construction, land and development — — — — — Home equity loans and lines of credit — — — — — Total real estate loans 6,206 727 — 116 7,049 Other loans: Commercial and industrial $ — $ — $ — $ — $ — Consumer — — — — — Total other loans — — — — — Total new loans $ 6,206 $ 727 $ — $ 116 $ 7,049 Acquired Loans: Real estate loans: Commercial real estate $ — $ — $ — $ 4,866 $ 4,866 Owner-occupied commercial real estate — — — 211 211 1-4 single family residential 1,877 86 — 1,766 3,729 Construction, land and development — — — — — Home equity loans and lines of credit 384 456 — 3,005 3,845 Total real estate loans 2,261 542 — 9,848 12,651 Other loans: Commercial and industrial $ — $ 192 $ — $ 1,222 $ 1,414 Consumer 14 — — — 14 Total other loans 14 192 — 1,222 1,428 Total acquired loans $ 2,275 $ 734 $ — $ 11,070 $ 14,079 Loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected may result in deterioration of the repayment capacity of the borrower are categorized as special mention. Loans with well-defined credit weaknesses including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable will be assigned an internal risk rating of doubtful.

Covered Assets and Loss Sharing Agreements	NOTE 6. COVERED ASSETS AND LOSS SHARING AGREEMENTS On March 4, 2015, the Bank entered into an agreement with the FDIC to terminate all loss sharing agreements which were entered into in 2010 and 2011 in conjunction with the Bank’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of six failed banks in FDIC-assisted acquisitions. Under the early termination agreements, all rights and obligations of the Bank and the FDIC under the loss share agreements, including the clawback provisions, have been eliminated. The Bank paid the FDIC $14.8 million as consideration for the early termination to settle its obligation under the FDIC Clawback Liability. The early termination was recorded in the Bank’s financial statements by removing the FDIC Indemnification Asset receivable, the FDIC Clawback liability and recording a one-time, pre-tax loss on termination of $65.5 million. The following table summarizes the carrying value of assets covered by the loss sharing agreements: December 31, 2015 2014 (Dollars in thousands) Loans, excluding allowance for loan losses $ — $ 273,366 OREO — 25,130 Total Covered Assets $ — $ 298,496 Subsequent to acquisition, when a provision for loan loss is required for a loan that is covered under a loss sharing agreement, the Company records an increase in the loss share indemnification asset and an increase to noninterest income in the consolidated statements of income based on the applicable loss sharing ratio. Increases in the loss share indemnification asset of $3.9 million and $2.2 million were included in noninterest income for the year ended December 31, 2014 and 2013, related to the provision for loan losses on Covered Loans, including both ASC 310-30 and Non-ASC 310-30 loans.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	NOTE 9. DERIVATIVES The Company is a party to interest rate derivatives that are not designated as hedging instruments. These derivatives are interest rate swaps that the Company enters into with customers to allow customers to convert variable rate loans to fixed rates. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. The changes in the fair value of the swaps offset each other, except for any differences in the credit risk of the counterparties, which is determined by considering the risk rating, probability of default and loss of given default of each counterparty. The Company recorded $5.2 million, $4.5 million and $3.3 million of customer swap fees in noninterest income in the accompanying consolidated statement of income for the years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015, the Company has not recorded any credit adjustments related to the credit risk of the counterparties. There was no change in the fair value of derivative assets and derivative liabilities attributable to credit risk included in noninterest expense on the statements of income for the years ended December 31, 2015, 2014 or 2013. No derivative positions held by the Company as of December 31, 2015 were designated as hedging instruments under ASC 815-10.

Regulatory Capital

Regulatory Capital	12 Months Ended
	Dec. 31, 2015
Banking and Thrift [Abstract]
Regulatory Capital	NOTE 12. REGULATORY CAPITAL The Company and the Bank are subject to regulatory capital adequacy requirements promulgated by federal regulatory agencies. The Board of Governors of the Federal Reserve System establishes capital requirements, including well capitalized standards, for the Company, and the OCC has similar requirements for the Bank. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. As of December 31, 2015 and 2014, all capital ratios of the Company and the Bank exceeded the well capitalized levels under the applicable regulatory capital adequacy guidelines. The ability of the Company and the Bank to pay dividends is subject to statutory and regulatory restrictions on the payment of cash dividends, including the requirement under the Florida banking laws that cash dividends be paid only out of undivided profits and only if the Company or the Bank have surplus of a specified level. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier I capital (as defined) to average assets (as defined). Management believes, at December 31, 2015 and 2014, that the Company and Bank met all capital adequacy requirements to which they are subject. The Bank’s and Company’s regulatory capital levels are as follows: Actual Minimum Capital Requirement Minimum To Be Well Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) December 31, 2015 Tier 1 leverage ratio Company $ 717,229 10.3 % $ 278,319 4.0 % $ 347,899 5.0 % Bank 678,608 9.9 % 273,721 4.0 % 342,151 5.0 % Common equity tier 1 capital ratio Company 717,229 12.1 % 267,511 4.5 % 386,405 6.5 % Bank 678,608 11.6 % 262,378 4.5 % 378,991 6.5 % Tier 1 risk-based capital ratio Company 717,229 12.1 % 356,682 6.0 % 475,576 8.0 % Bank 678,608 11.6 % 349,838 6.0 % 466,450 8.0 % Total risk-based capital ratio Company 717,229 12.1 % 475,576 8.0 % 594,470 10.0 % Bank 678,608 11.6 % 466,450 8.0 % 583,063 10.0 % December 31, 2014 Tier 1 leverage ratio Company $ 752,175 12.8 % $ 234,991 4.0 % $ 293,739 5.0 % Bank 598,517 10.4 % 229,828 4.0 % 287,285 5.0 % Tier 1 risk-based capital ratio Company 752,175 17.0 % 176,798 4.0 % 265,197 6.0 % Bank 598,517 13.9 % 172,315 4.0 % 258,473 6.0 % Total risk-based capital ratio Company 776,290 17.6 % 353,596 8.0 % 441,995 10.0 % Bank 622,632 14.5 % 344,631 8.0 % 430,788 10.0 % The FDIC Order that the Bank entered into upon the acquisition of Old Premier requires the institution to maintain a ratio of Tier 1 common equity to total assets of at least 10% for a period of three years following its first FDIC-assisted transaction, and thereafter maintain a capital level sufficient to be well capitalized under regulatory standards during the remaining period of ownership of the investors subject to the FDIC Order. The Bank is currently subject to the well capitalized requirement but is no longer subject to the 10% Tier 1 common equity ratio requirement. The Bank is subject to regulations of certain federal and state agencies and can be periodically examined by those authorities. As a consequence, the Bank’s business is susceptible to the impacts of federal legislation and regulations issued by, but not limited to, the Board of Governors of the Federal Reserve System, OCC and FDIC.

STOCKHOLDERS’ EQUITY Class A and Class B Common Stock The shares of common stock of the Company are divided into two classes: Class A common stock and Class B common stock. The Class A common stock possesses all of the voting power for all matters requiring action by holders of the Company’s common stock, with certain limited exceptions. Each share of Class B common stock is convertible into one share of Class A common stock, subject to certain restrictions. The Class A common stock is not convertible. Other than with respect to voting rights and the restrictions on transfer and conversion relating to the Class B common stock, the Class A common stock and the Class B common stock are treated equally and identically, including with respect to distributions. In 2015 and 2014, the Company converted 3,206,166 and 887,104, respectively, Class B common shares to Class A common shares in a voluntary exchange with certain shareholders. This exchange was made on 1:1 ratio and no consideration was paid or received by the Company. Total Class B common shares issued and outstanding decreased by 3,206,166 and 887,104 while Class A common shares issued and outstanding increased by 3,206,166 and 887,104 for the years ended December 31, 2015 and 2014. This is recorded as “Exchange of B shares to A shares” in the consolidated statements of changes in stockholders’ equity. Preferred Stock There are 10 million preferred shares authorized and none issued and outstanding at December 31, 2015. Preferred stock has a par value of $.001. Treasury Stock During the year ended December 31, 2015, the Company repurchased 1,050,062 shares of Class A common stock at a weighted average price of $33.20 per share for an aggregate amount of $34.9 million from shareholders. The Company accounted for the transactions under the cost method and holds 2,169,506 common shares with a cost of $53.6 million in Treasury Stock as of December 31, 2015. These transactions are recorded as “Treasury stock purchases” in the accompanying consolidated statements of changes in stockholders’ equity. Warrants During 2009, the Company issued, as a distribution in respect of its existing equity, warrants to purchase an aggregate of 3,310,428 shares of Class A common stock (the “2009 Warrants”). The 2009 Warrants provide the recipient a right to purchase one share of Class A common stock for an exercise price ranging between $24.24 and $28.28 per warrant. The recipients can only exercise the warrants on the sixth, eighteenth, and thirtieth month anniversaries of the occurrence of a Qualified IPO. The Company’s public offering constituted a Qualified IPO with respect to the Company’s Amended 2009 Warrants. Prior to December 31, 2013, the Company had not recorded any expense in the accompanying consolidated financial statements associated with the Original 2009 Warrants as it was a distribution in respect of its then existing equity. On November 19, 2013, the Company amended the 2009 Warrants (the “Amended 2009 Warrants”) whereby the exercise period and expiration date was extended to November 12, 2019. The Amended 2009 Warrants also provide clarification for certain matters relating to the definition of a “Special Transaction”. The incremental change in fair value of the Amended 2009 Warrants was determined utilizing the Black-Scholes pricing model methodology as of November 19, 2013, the date of amendment, compared to the fair value of the Original 2009 Warrants immediately prior to the modification. The amount related to the change in fair value resulting from the modification at grant date was $4.0 million. The assumptions used to calculate the fair values of the Original 2009 Warrants and Amended 2009 Warrants are summarized below: Original Amended Expected volatility 30.0 % 30.0 % Expected dividend yield 2.5 % 2.5 % Expected term (years) 3.0 6.0 Risk-free interest rate 0.58 % 1.70 % Weighted average fair value (per warrant) $ 1.28 $ 2.49 Total fair value (in thousands) $ 4,226 $ 8,254 Since the Company’s common stock did not trade on any exchange at the time of the modification, the expected volatility is based on the volatility of comparable peer banks. The expected term represents the period of time that the 2009 warrants are expected to be outstanding from the amendment date. The risk-free interest rate is based on the US Treasury yields for the expected term of the instrument. The following table presents the activity during the year ended December 31, 2015 related to the Amended 2009 Warrants: Amended 2009 Warrants Warrants Weighted Aggregate Weighted (Dollars in thousands, exept per share data) Outstanding at January 1, 2015 3,310,428 $ 26.23 Granted — — Exercised (286,305 ) 24.24 $ 2,367 Forfeited — — Expired — — Outstanding at December 31, 2015 3,024,123 26.42 28,330 3.87 Exerciable at December 31, 2015 817,170 24.24 9,438 3.87 Vested at December 31, 2015 3,024,123 26.42 28,330 3.87 Vested and expected to vest at December 31, 2015 3,024,123 26.42 28,330 3.87 As of December 31, 2015, there were 3,024,123 outstanding 2009 Warrants with an expiration date of November 12, 2019. There is no remaining expense to be recognized from the Amended 2009 Warrants. During 2010, the Company issued warrants to directors and employees to purchase an aggregate of 2,142,000 shares of Class A common stock (the “2010 Warrants”). The 2010 Warrants provided the recipient a right to purchase one share of Class A common stock for an exercise price at December 31, 2012 ranging between $26 and $32 per warrant. All 2010 Warrants were relinquished by the recipients and cancelled (the “Cancellation”) by the Company in 2013. The Company has not recorded any expense in the accompanying consolidated financial statements associated with the 2010 Warrants or the Cancellation of the 2010 Warrants as a Qualified IPO did not occur on or prior to the Cancellation. The holders of the 2010 Warrants received replacement awards in the form of stock options and restricted stock units (the “2013 RSUs”) from the 2013 Incentive Plan. The Company has accounted for this as a modification. Refer to Note 15 “Stock-based Compensation and Other Benefit Plans” for more information and calculation of the fair value modification.

STOCK-BASED COMPENSATION AND OTHER BENEFIT PLANS 2009 Equity Incentive Plan In 2009, the Company approved the 2009 Equity Incentive Plan (the “2009 Option Plan”) covering its directors, employees and affiliates. The 2009 Option Plan provided for the grant of options to acquire shares of common stock up to an aggregate of the lesser of 10% of issued common stock or 4.375 million shares of common stock. When the options are exercised, the shares issued upon such exercise will be newly issued shares. On four different dates in 2013, the Company granted an aggregate of 370,499 options to employees with a Three Year Vesting Period and a weighted average exercise price of $19.63. The options granted to employees expire 10 years from grant date. Also in 2013, the Company granted 70,000 stock options to directors without vesting requirements and a weighted average exercise price of $19.25. The options granted to directors can be exercised within 10 years from grant date. On three different dates in 2014, the Company granted an aggregate of 605,250 options with a Three Year Vesting Period from the 2009 Option Plan to employees with a weighted average exercise price of $21.99, the estimated fair value of the Company’s stock on the date of grant, and an aggregate fair value of $4.5 million. The options granted to employees expire 10 years from grant date. Also in 2014, the Company granted 90,000 options from the 2009 Option Plan to directors that vest at a rate of 25% per calendar quarter in 2014. The options have an exercise price of $19.75, the estimated fair value of the Company’s stock on the date of grant and an aggregate fair value of $0.5 million. The options granted to directors expire 10 years from grant date. In November 2014, the 2009 Option Plan expired on the fifth anniversary of plan’s adoption date. As of December 31, 2014, there are no remaining awards available from the 2009 Option Plan. The following tables present the activity during the year ended December 31, 2015 related to the 2009 Option Plan: 2009 Option Plan Options Weighted Aggregate Weighted (Dollars in thousands, exept per share data) Outstanding at January 1, 2015 4,135,250 $ 20.67 Granted — — Exercised (395,603 ) 20.63 $ 4,940 Forfeited (30,247 ) 20.71 Expired (1,502 ) 22.97 Outstanding at December 31, 2015 3,707,898 20.67 56,068 5.89 Exercisable at December 31, 2015 3,206,683 20.54 48,894 5.49 Vested at December 31, 2015 3,206,683 20.54 48,894 5.49 Vested and expected to vest at December 31, 2015 3,707,790 20.67 56,067 5.89 The fair values of the stock options granted for the years ended December 31, 2014 and 2013 were determined utilizing the Black-Scholes pricing model methodology. No awards were granted from the 2009 Option Plan during the year ended December 31, 2015. A summary of assumptions used to calculate the fair values of the 2009 Option Plan awards is presented below: 2009 Option Plan Year Ended December 31, 2015 2014 2013 Expected volatility 0.0 % 33.6 - 36.7 % 33.6 - 36.4 % Expected dividend yield 0.0 % 1.3 - 2.5 % 2.5 % Expected term (years) — 5.5 - 6.5 5.0 - 6.5 Risk-free interest rate 0.00 % 2.32 - 2.70 % 1.89 - 2.69 % Weighted average grant date fair value $ — $ 7.14 $ 5.44 The expected volatility is based on the volatility of comparable peer banks. The expected term represents the period of time that the 2009 Option Plan awards are expected to be outstanding from the date of grant. The risk-free interest rate is based on the US Treasury yields for the expected term of the instrument. A summary of selected data related to stock-based compensation expense follows: 2009 Option Plan Year Ended December 31, 2015 2014 2013 (Dollars in thousands) Stock-based compensation expense $ 2,239 $ 2,125 $ 2,635 Tax benefit realized from stock awards exercised 1,618 — — Fair value of stock-based awards that vested during the year 2,724 2,319 2,924 Amount of cash received from exercise of awards 8,163 — — Total intrisic value of awards exercised during the year 4,940 — — 2009 Option Plan December 31, 2015 2014 2013 (Dollars in thousands) Unrecognized compensation expense related to stock-based compensation $ 2,561 $ 4,949 $ 2,396 Weighted-average life over which expense is expected to be recognized (years) 1.72 2.54 2.27 2013 Stock Incentive Plan In 2013, the Company approved the 2013 Stock Incentive Plan (the “2013 Incentive Plan”) covering its executive management, directors, individual consultants and employees. The 2013 Incentive Plan provides that awards may be granted under the plan with respect to an aggregate of 3,000,000 shares of common stock of the Company. Awards may be made under the 2013 Incentive Plan in the form of (a) incentive stock options, (b) options that do not qualify as incentive stock options, (c) stock appreciation rights, (d) restricted stock, (e) restricted stock units and (f) unrestricted stock; provided, that the number of shares of restricted stock, restricted stock units, and shares of unrestricted stock awarded under the Plan shall not exceed 500,000, in the aggregate. When the options are exercised, the shares issued upon such exercise will be newly issued shares. On August 6, 2014, the Company completed the initial public offering of 7,520,000 shares of Class A common stock for $22.00 per share. This public offering constituted a “Qualified IPO” with respect to the Company’s Option awards (“2013 Plan Options”) and 2013 Stock Incentive Plan Restricted Stock Units (“2013 RSUs”). During the year ended December 31, 2014, the Company recognized $5.5 million in expense resulting from the Plan Options as a “Qualified IPO” transaction was completed. During 2013, all 2010 Warrants were relinquished by the recipients and cancelled by the Company. The holders of the 2010 Warrants received replacement awards in the form of 2013 Plan Options and 2013 RSUs. The Company has accounted for this as a modification and recognized the fair value of the cancelled 2010 Warrants as a reduction to 2013 Incentive Plan expense. The amount related to the change in fair value resulting from the 2010 Warrants at the cancellation date was $1.5 million and was recorded in the consolidated financial statements at the completion of the Qualified IPO. A summary of assumptions used to calculate the fair values of the cancelled 2010 Warrants is presented below: Original Original Expected volatility 30.0 % 30.0 % Expected dividend yield 2.5 % 2.5 % Expected term (years) 3.6 — Risk-free interest rate 1.06 % 1.06 % Weighted average fair value (per warrant) $ 0.70 $ — Total fair value (in thousands) $ 1,499 $ — 2013 Incentive Plan – Stock Options On December 23, 2013, the Company granted 1,500,000 options with immediate vesting and 673,000 options that vest in equal installments over a period of three years.

Basic and Diluted Earnings Per Share	NOTE 16. BASIC AND DILUTED EARNINGS PER SHARE Basic EPS is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the effect of common stock equivalents, including stock options and unvested shares, calculated using the treasury stock method. Common stock equivalents are excluded from the computation of diluted EPS in periods in which the effect is anti-dilutive.

The significant components of the net deferred tax assets and liabilities for the periods presented are as follows: December 31, 2015 2014 (Dollars in thousands) Deferred tax assets: Excess tax basis over carrying value of assets: Other real estate owned $ 15,740 $ 17,508 Total 15,740 17,508 Excess carrying value over tax basis of liabilities: Deposits 19 147 Repo Loans 1,330 2,344 Clawback liability — 5,326 Total 1,349 7,817 Net operating loss carry forward: Federal 9,790 10,378 State 971 1,029 Total 10,761 11,407 Amortization 25,052 23,569 Depreciation 848 2,119 Unrealized losses on securities available for sale 5,930 — Allowance for loan losses 9,468 33,100 Non-qualified stock options 6,458 6,955 Other 2,794 3,259 Gross deferred tax assets 78,400 105,734 Valuation allowance — (9,151 ) Gross deferred tax assets, net of valuation allowance 78,400 96,583 Deferred tax liabilities: Loans (966 ) (19,072 ) Restricted securities (2,257 ) (2,274 ) Loss-share indemnification — (24,210 ) Deferred tax gain — (2,741 ) Unrealized gains on securities available for sale — (410 ) Other (1 ) (435 ) Gross deferred tax liabilities (3,224 ) (49,142 ) Deferred tax assets (liabilities), net $ 75,176 $ 47,441 At December 31, 2015, the Company had deferred tax assets for federal and state net operating losses of $9.8 million and $971 thousand, respectively. The federal and state net operating loss carryforwards are attributable to the acquisition of Great Florida Bank and are subject to an annual limitation. These deferred tax assets for net operating losses will expire in years 2028 through 2034. The Company records a valuation allowance to reduce its deferred tax assets if, based on the weight of available evidence, both positive and negative, for each respective tax jurisdiction, it is more likely than not that some portion or all of such deferred tax assets will not be realized. Management believes the Company will realize the benefits from certain federal and state net operating loss carryforwards and as such, in 2015, has reversed the valuation allowance of $9.1 million previously provided on the deferred tax assets for federal and state net operating loss carryforwards. The reversal of the valuation allowance on the deferred tax assets was recognized as a reduction of income tax expense. The Company is subject to U.S. federal income tax as well as state income tax of Florida and New York. The Company’s federal income tax returns for 2011 through the current period remain subject to examination and the relevant state statutes vary. The Florida Department of Revenue has notified the Company of its intent to examine income tax returns for the years 2011 through 2013. The Company does not expect an assessment of any significant additional tax. The Company had no uncertain tax positions at December 31, 2015, 2014 or 2013. The Company’s policy is to classify interest and penalties associated with income taxes within other expenses. The Company did not incur interest and penalties associated with income taxes at December 31, 2015, 2014 or 2013.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 18. COMMITMENTS AND CONTINGENCIES The Company issues off-balance sheet financial instruments in connection with its lending activities and to meet the financing needs of its customers. These financial instruments include commitments to fund loans and lines of credit as well as commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers. The Company follows the same credit policies in making commitments as it does for instruments recorded on the Company’s consolidated balance sheet. Collateral is obtained based on management’s assessment of the customer’s credit risk. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. As of December 31, 2015 and 2014, the Company’s reserve for unfunded commitments totaled $1.5 million and $1.2 million, respectively. Fees collected on off-balance sheet financial instruments represent the fair value of those commitments and are deferred and amortized over their term. Financial Instruments Commitments Unfunded commitments are as follows: December 31, 2015 2014 (Dollars in thousands) Commitments to fund loans $ 578,730 $ 351,369 Unused lines of credit 358,601 199,880 Commercial and standby letters of credit 14,410 10,223 Total $ 951,741 $ 561,472 Commitments to fund loans: Commitments to fund loans are agreements to lend funds to customers as long as there is no violation of any condition established in the contract. To accommodate the financial needs of customers, the Company makes commitments under various terms to lend funds to consumers and businesses. Commitments to fund loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of these commitments are expected to expire without being funded and, therefore, the total commitment amounts do not necessarily represent future liquidity requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral required in connection with a commitment to fund is based on management’s credit evaluation of the counterparty. Unused lines of credit: Unfunded commitments under lines of credit include commercial, commercial real estate, home equity and consumer lines of credit to existing customers. Some of these commitments may mature without being fully funded. Commercial and standby letters of credit: Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company generally holds collateral supporting those commitments if deemed necessary. Other Commitments and Contingencies Legal Proceedings The Company, from time to time, is involved as plaintiff or defendant in various legal actions arising in the normal course of business. While the ultimate outcome of any such proceedings cannot be predicted with certainty, it is the opinion of management, based upon advice of legal counsel, that no proceedings exist, either individually or in the aggregate, which, if determined adversely to the Company, would have a material effect on the Company’s consolidated balance sheet, results of operations or cash flows. A bank-owned asset in Miami-Dade County was foreclosed in 2012, and later discovered to have been illegally infilled over protected wetlands by the prior owner. The bank has been working with Miami-Dade County environmental agencies to address the situation, along with Bank environmental attorneys specializing in this area. The subject property was sold during Q1 2015 to a third party purchaser and the Bank has no further legal liability for the asset. The SEC is investigating the valuation and accounting treatment by GFB, prior to the Great Florida Acquisition by the Company, of an office building acquired by GFB in 2009 and the use of appraisals with respect to such valuation. The Bank is cooperating with the investigation. On the date of acquisition by the Bank, based on the Company’s plans and intended use of the acquired office building, the asset was classified as OREO and recorded at fair value, less estimated selling costs. The fair value of the office building was based on a third party real estate appraisal at the date of acquisition. The Company does not believe that the results of the SEC investigation relating to GFB are likely to have a material adverse effect on the financial condition or results of operations of the Company. The subject property was sold during Q2 2015 to a third party purchaser.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 20. FAIR VALUE MEASUREMENTS When determining the fair value measurements for assets and liabilities and the related fair value hierarchy, the Company considers the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to market observable data for similar assets and liabilities. It is the Company’s policy to maximize the use of observable inputs, minimize the use of unobservable inputs and use unobservable inputs to measure fair value to the extent that observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity, resulting in diminished observability of both actual trades and assumptions that would otherwise be available to value these instruments, or the value of the underlying collateral is not market observable. Although third party price indications may be available for an asset or liability, limited trading activity would make it difficult to support the observability of these quotations. Financial Instruments Carried at Fair Value on a Recurring Basis The following is a description of the valuation methodologies used for financial instruments measured at fair value on a recurring basis, as well as the general classification of each instrument under the valuation hierarchy. Investment Securities—Investment securities available for sale are carried at fair value on a recurring basis. When available, fair value is based on quoted prices for the identical security in an active market and as such, would be classified as Level 1. If quoted market prices are not available, fair values are estimated using quoted prices of securities with similar characteristics, discounted cash flows or matrix pricing models. Investment securities available for sale for which Level 1 valuations are not available are classified as Level 2, and include U.S. Government agencies and sponsored enterprises obligations and agency mortgage-backed securities; state and municipal obligations; asset-backed securities; and corporate debt and other securities. Pricing of these securities is generally spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities. Interest Rate Derivatives—Interest rate derivatives are reported at estimated fair value utilizing Level 2 inputs and are included in other assets and other liabilities and consist of interest rate swaps where there is no significant deterioration in the counterparties (loan customers) credit risk since origination of the interest rate swap. The Company values its interest rate swap positions using market prices provided by a third party which uses primarily observable market inputs. Interest rate derivatives are further described in Note 9 “Derivatives.” For purposes of potential valuation adjustments to our derivative positions, the Company evaluates the credit risk of its counterparties as well as our own credit risk. Accordingly, the Company has considered factors such as the likelihood of default, expected loss given default, net exposures and remaining contractual life, among other things, in determining if any estimated fair value adjustments related to credit risk are required. The Company reviews counterparty exposure quarterly, and when necessary, appropriate adjustments are made to reflect the exposure. For the years ended December 31, 2015, 2014 or 2013, the Company has not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. As of December 31, 2015, there were no interest rate derivatives classified as Level 3. Contingent consideration issued to the FDIC—In conjunction with the 2010 and 2011 acquisitions, the Bank issued contingent consideration to the FDIC in the form of VAIs and EAAs. The estimated fair value of the VAIs and EAAs are derived from an estimation of the future fair value of the Company’s stock and a range of potential payment liabilities is determined in accordance with the terms of each agreement. Management assigns a probability to each potential payment liability based on its judgment about the likelihood of the event occurring. This expected value is the basis for estimating the fair value of the contingent consideration. As of December 31, 2015, the Company had no remaining VAIs or EAAs, as the VAIs reached final settlement with the FDIC within the year ended December 31, 2013, and the EAAs reached final settlement with the FDIC on September 29, 2014. Clawback liability—The fair value of the FDIC clawback liability is estimated using a discounted cash flow technique based on projected cash flows related to the resolution of Covered Assets and a discount rate using a risk free rate, plus a premium that takes into account the Company’s credit risk, resulting in Level 3 classification. On March 4, 2015, the Bank entered into an agreement with the FDIC to terminate all loss sharing agreements which were entered into in 2010 and 2011 in conjunction with the Bank’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of six failed banks in FDIC-assisted acquisitions. Under the early termination, all rights and obligations of the Bank and the FDIC under the loss share agreements, including the clawback liability, have been eliminated. The following table presents the assets and liabilities measured at fair value on a recurring basis: December 31, 2015 Level 1 Level 2 Level 3 Total (Dollars in thousands) Assets: U.S. Government agencies and sponsored enterprises obligations $ — $ 20,888 $ — $ 20,888 U.S. Government agencies and sponsored enterprises mortgage-backed securities — 393,115 — 393,115 State and municipal obligations — 2,215 — 2,215 Asset-backed securities — 493,934 — 493,934 Corporate bonds and other debt securities — 444,895 — 444,895 Preferred stocks and other equity securities 2,052 167,523 — 169,575 Derivative assets—Interest rate contracts — 21,553 — 21,553 Total $ 2,052 $ 1,544,123 $ — $ 1,546,175 Liabilities: Derivative liabilities—Interest rate contracts $ — $ 21,553 $ — $ 21,553 Clawback liability — — — — Total $ — $ 21,553 $ — $ 21,553 December 31, 2014 Level 1 Level 2 Level 3 Total (Dollars in thousands) Assets: U.S. Government agencies and sponsored enterprises obligations $ — $ 6,096 $ — $ 6,096 U.S. Government agencies and sponsored enterprises mortgage-backed securities — 501,652 — 501,652 State and municipal obligations — 2,277 — 2,277 Asset-backed securities — 478,201 — 478,201 Corporate bonds and other debt securities — 258,683 — 258,683 Preferred stocks and other equity securities 23,594 88,595 — 112,189 Derivative assets—Interest rate contracts — 14,328 — 14,328 Total $ 23,594 $ 1,349,832 $ — $ 1,373,426 Liabilities: Derivative liabilities—Interest rate contracts $ — $ 14,328 $ — $ 14,328 Clawback liability — — 13,846 13,846 Total $ — $ 14,328 $ 13,846 $ 28,174 There were no transfers of financial assets between levels of the fair value hierarchy during the year ended December 31, 2015 or 2014. The following tables reconcile changes in the fair value of liabilities measured at fair value on a recurring basis and classified in level 3 of the fair value hierarchy for the periods presented: Years Ended December 31, 2015 2014 2013 Clawback EAAs Clawback EAAs Clawback VAIs and (Dollars in thousands) Balance at beginnning of period $ 13,846 $ — $ 11,753 $ 1,114 $ 11,966 $ 1,235 Losses (gains) included in other noninterest expenses — — 2,093 1,466 (213 ) 482 Termination of FDIC loss sharing agreements (13,846 ) — — — — — Final VAI settlement on SSCB — — — — — (52 ) Final VAI settlement on FNBCF — — — — — (281 ) Final VAI settlement on FPB — — — — — (270 ) Final EAA settlement on FCB — — — (1,458 ) — — Final EAA settlement on PAB — — — (1,122 ) — — Balance at end of period $ — $ — $ 13,846 $ — $ 11,753 $ 1,114 The inputs used to determine the estimated fair value of loans include market conditions, loan term, underlying collateral characteristics and discount rates. The inputs used to determine fair value of OREO include market conditions, estimated marketing period or holding period, underlying collateral characteristics and discount rates. For the years ended December 31, 2015 and 2014, there was not a change in the methods or significant assumptions used to estimate fair value. Financial Instruments Measured at Fair Value on a Non-Recurring Basis The following table shows significant unobservable inputs used in the non-recurring fair value measurement of level 3 assets and liabilities: Level 3 Asset Fair value Valuation Technique Unobservable Inputs Range (Dollars in thousands) Non-recurring: Loans $ 5,207,971 Third party appraisals and discounted cash flows Collateral discounts and discount rates 0% - 100% Other real estate owned 39,340 Third party appraisals Collateral discounts and estimated cost to sell 10% The following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified. Impaired loans and OREO—The carrying amount of collateral dependent impaired loans is typically based on the fair value of the underlying collateral, which may be real estate or other business assets, less estimated costs to sell. The carrying value of OREO is initially measured based on the fair value, less estimated cost to sell, of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral are typically based on real estate appraisals which utilize market and income valuation techniques incorporating both observable and unobservable inputs. When current appraisals are not available, the Company may use brokers’ price opinions, home price indices, or other available information about changes in real estate market conditions to adjust the latest appraised value available. These adjustments to appraised values may be subjective and involve significant management judgment. The fair value of collateral consisting of other business assets is generally based on appraisals that use market approaches to valuation, incorporating primarily unobservable inputs. Fair value measurements related to collateral dependent impaired loans and OREO are classified within level 3 of the fair value hierarchy. The following tables provide information about certain assets measured at fair value on a non-recurring basis: December 31, 2015 2014 (Dollars in thousands) Assets that are still held (classified in Level 3): Impaired loans $ 9,582 $ 4,754 Foreclosed real estate 39,340 74,527 Years Ended December 31, 2015 2014 2013 (Dollars in thousands) Negative valuation adjustments: Impaired loans $ 1,071 $ 174 $ 149 Foreclosed real estate 674 1,829 2,047 Impairment charges resulting from the non-recurring changes in fair value of underlying collateral of impaired loans are included in the provision for loan losses in the consolidated statement of income. Impairment charges resulting from the non-recurring changes in fair value of OREO are included in other real estate and acquired assets resolution expenses in the consolidated statement of income. The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments are as follows: December 31, 2015 Carrying Fair Level 1 Level 2 Level 3 (Dollars in thousands) Financial Assets: Cash and cash equivalents $ 102,460 $ 102,460 $ 102,460 $ — $ — Available for sale securities 1,524,622 1,524,622 2,052 1,522,570 — FHLB and other bank stock 59,477 59,477 — 59,477 — Loans, net 5,164,061 5,207,971 — — 5,207,971 Loans held for sale 2,514 2,514 — 2,514 — Loss share indemnification asset — — — — — Due from FDIC — — — — — Bank-owned life insurance 168,246 168,246 — 168,246 — Derivative assets—Interest rate contracts 21,553 21,553 — 21,553 — Financial Liabilities: Deposits $ 5,430,638 $ 5,430,501 $ — $ 5,430,501 $ — Advances from the FHLB and other borrowings 983,183 981,997 — 981,997 — Derivative liabilities—Interest rate contracts 21,553 21,553 — 21,553 — Clawback liability — — — — — December 31, 2014 Carrying Fair Level 1 Level 2 Level 3 (Dollars in thousands) Financial Assets: Cash and cash equivalents $ 107,085 $ 107,085 $ 107,085 $ — $ — Available for sale securities 1,359,098 1,359,098 23,594 1,335,504 — FHLB and other bank stock 66,891 66,891 — 66,891 — Loans, net 3,906,710 3,959,771 — — 3,959,771 Loans held for sale 707 707 — 707 — Loss share indemnification asset 63,168 27,976 — — 27,976 Due from FDIC 1,735 1,735 — 1,735 — Bank-owned life insurance 139,829 139,829 — 139,829 — Derivative assets—Interest rate contracts 14,328 14,328 — 14,328 — Financial Liabilities: Deposits $ 3,978,535 $ 3,977,629 $ — $ 3,977,629 $ — Advances from the FHLB and other borrowings 1,067,981 1,066,764 — 1,066,764 — Derivative liabilities—Interest rate contracts 14,328 14,328 — 14,328 — Clawback liability 13,846 13,846 — — 13,846 Certain financial instruments are carried at amounts that approximate fair value due to their short-term nature and generally negligible credit risk. Financial instruments for which fair value approximates the carrying amount at December 31, 2015 and December 31, 2014, include cash and cash equivalents and due from FDIC. The following methods and assumptions were used to estimate the fair value of each class of financial instruments. FHLB and Other Bank Stock: FHLB and other bank stock can be liquidated only by redemption by the issuer, as there is no market for these securities. These securities are carried at par, which has historically represented the redemption price and is therefore considered to approximate fair value. Loans: Fair values for loans are based on a discounted cash flow methodology that considers various factors, including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, whether or not the loan was amortizing and current discount rates. Loans are grouped together according to similar characteristics and are treated in the aggregate when applying various valuation techniques. The discount rates used for loans are based on current market rates for new originations of comparable credit risk and include adjustments for liquidity concerns. The ALL is considered a reasonable estimate of the required adjustment to fair value to reflect the impact of credit risk. This estimate may not represent an exit value as defined in ASC 820. Loans Held for Sale: Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices. Loss Share Indemnification Asset: The fair value of the loss share indemnification asset is estimated using a discounted cash flow technique based on projected cash flows related to the resolution of Covered Assets and a discount rate using a risk free rate, plus a premium to take into account the Company’s credit risk, that incorporates the uncertainty related to the amounts and timing of the cash flows and other liquidity concerns as well as the counterparties credit risk. As of December 31, 2015, the Company had no remaining loss share indemnification asset, as the Bank entered into an agreement with the FDIC to terminate all loss sharing agreements on March 4, 2015. Due from FDIC: The due from FDIC represents claims submitted to the Federal Deposit Insurance Corporation for reimbursement for which the Company expects to receive payment within 90 days. Due to their short term nature, the carrying amount of these instruments approximates the estimated fair value. As of December 31, 2015, the Company had no remaining receivable from the FDIC, as the Bank entered into an agreement with the FDIC to terminate all loss sharing agreements on March 4, 2015. Bank-owned Life Insurance: The Company holds life insurance policies on certain officers. The carrying value of these policies approximates fair value as it is based on the cash surrender value adjusted for other charges or amounts due that are probable at settlement. Deposits: The fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using discounted cash flow analysis and using the rates currently offered for deposits of similar remaining maturities. Advances from the FHLB and Other Borrowings: The fair value of advances from the FHLB and other borrowings are estimated by discounting the future cash flows using the current rate at which similar borrowings with similar remaining maturities could be obtained. VAIs and EAAs: The estimated fair value of EAAs are derived from an estimation of the future fair value of the Company’s stock and a range of potential payment liabilities are determined in accordance with the terms of each agreement. As of December 31, 2015, the Company had no remaining VAIs or EAAs, as the VAIs reached final settlement with the FDIC within the year ended December 31, 2013, and the EAAs reached final settlement with the FDIC on September 29, 2014.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations FCB Financial Holdings, Inc. (the “Company”), formerly known as Bond Street Holdings, Inc., is a national bank holding company with one wholly-owned national bank subsidiary, Florida Community Bank, N.A. (“Florida Community Bank” or the “Bank”), headquartered in Weston, Florida, offering a comprehensive range of traditional banking products and services to individual and corporate customers through 49 banking centers located in Florida at December 31, 2015.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank’s subsidiaries, which consist of a group of real estate holding companies. Intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The Company’s financial reporting and accounting policies conform to U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates subject to significant change include the allowance for loan losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, contingent consideration liabilities, acquisition-related fair value computations, stock-based compensation and deferred taxes.
Off-Balance Sheet Arrangements	Off-Balance Sheet Arrangements The Company enters into contractual loan commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Since a portion of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Substantially all of the commitments to extend credit are contingent upon customers maintaining specific credit standards until the time of loan funding. The Company decreases its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements. The Company assesses the credit risk associated with certain commitments to extend credit and establish a liability for probable credit losses. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company records a reserve in the amount considered adequate to absorb estimated losses. Since the Company has limited credit loss history, management performs an analysis of reserve rates for banks in the FFIEC Group 1 – “Commercial Banks with assets >$3 Billion”. This analysis involves calculating an average reserve rate for unfunded commitments using a rolling eight quarter basis of the most recent data available. Based on this peer group analysis, FCB records a reserve for unfunded commitments calculated using a rate in line with peer banks.
Business combinations	Business combinations The Company accounts for transactions that meet the definition of a purchase business combination by recording the assets acquired and liabilities assumed at their fair value upon acquisition. The operations of the acquisitions are included in the consolidated financial statements from the date of acquisition. Intangible assets, indemnification contracts and contingent consideration are identified and recognized individually. If the fair value of the assets acquired exceeds the purchase price plus the fair value of the liabilities assumed, a bargain purchase gain is recognized. Conversely, if the purchase price plus the fair value of the liabilities assumed exceeds the fair value of the assets acquired, goodwill is recognized. The Company’s assumptions utilized to determine the fair value of assets acquired and liabilities assumed conform to market conditions at the date of acquisition. The provisional amounts recorded are updated if better information is obtained about the initial assumptions used to determine fair value or if new information is obtained regarding the facts and circumstances that existed at the date of acquisition. The provisional amounts may be adjusted through the completion of the measurement period, which does not exceed one year from the date of acquisition.
Fair Value Measurement	Fair Value Measurement The Company uses estimates of fair value in applying various accounting standards for its consolidated financial statements on either a recurring or non-recurring basis. Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between willing and able market participants. The Company groups its assets and liabilities measured at fair value in three hierarchy levels, based on the observability and transparency of the inputs. These levels are as follows: Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; Level 2—Observable inputs other than level 1 inputs, including quoted prices for similar assets and liabilities, quoted prices for identical assets and liabilities in less active markets and other inputs that can be corroborated by observable market data; Level 3—Unobservable inputs supported by limited or no market activity or data and inputs requiring significant management judgment or estimation; valuation techniques utilizing level 3 inputs include option pricing models, discounted cash flow models and similar techniques. It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs in estimating fair value. Unobservable inputs are utilized in determining fair value estimates only to the extent that observable inputs are not available. The need to use unobservable inputs generally results from a lack of market liquidity and trading volume. Transfers between levels of fair value hierarchy are recorded at the end of the reporting period. Accounting Standards Codification (“ASC”) Topic 825, Financial Instruments, allows the Company an irrevocable option for measurement of eligible financial assets or financial liabilities at fair value on an instrument by instrument basis (the fair value option). An election may be made at the time an eligible financial asset, financial liability or firm commitment is recognized or when certain specified reconsideration events occur. The Company has not elected the fair value option for any eligible financial instrument as of December 31, 2015 and 2014.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. A gain or loss is recognized in earnings upon completion of the sale based on the difference between the sales proceeds and the carrying value of the assets. Control over the transferred assets is deemed to have been surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, interest-bearing deposits with banks, Federal funds sold and securities purchased under resale agreements or similar arrangements. Cash and cash equivalents have original maturities of three months or less. Accordingly, the carrying amount of such instruments is considered a reasonable estimate of fair value. The Company’s balances maintained may at times exceed federal depository insurance limits. The Bank is required to maintain reserve balances with the FRB. Such reserve requirements are based on a percentage of deposit liabilities and may be satisfied by cash on hand. The reserve balance requirement was $25.0 million as of December 31, 2015.
Investment Securities	Investment Securities The Company determines the classification of investment securities at the time of purchase. If the Company has the intent and the ability at the time of purchase to hold debt securities until maturity, they are classified as held-to-maturity. Investment securities held-to-maturity are stated at amortized cost. Debt securities the Company does not intend to hold to maturity are classified as available for sale and carried at estimated fair value with unrealized gains or losses reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), net of applicable income taxes. Available for sale securities are a part of the Company’s asset/liability management strategy and may be sold in response to changes in interest rates, prepayment risk or other market factors. Interest income and dividends on securities are recognized in interest income on an accrual basis. Premiums and discounts on debt securities are amortized as an adjustment to interest income over the period to maturity of the related security using the effective interest method. Realized gains or losses on the sale of securities are determined using the specific identification method. The Company reviews investment securities for impairment on a quarterly basis or more frequently if events and circumstances warrant. In order to determine if a decline in fair value below amortized cost represents OTTI, management considers several factors, including but not limited to, the length of time and extent to which the fair value has been less than the amortized cost basis, the financial condition and near-term prospects of the issuer (considering factors such as adverse conditions specific to the issuer and the security and ratings agency actions) and the Company’s intent and ability to retain the investment in order to allow for an anticipated recovery in fair value. The Company recognizes OTTI of a debt security for which there has been a decline in fair value below amortized cost if (i) management intends to sell the security, (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, or (iii) the Company does not expect to recover the entire amortized cost basis of the security. The amount by which amortized cost exceeds the fair value of a debt security that is considered to have OTTI is separated into a component representing the credit loss, which is recognized in earnings, and a component related to all other factors, which is recognized in other comprehensive income (loss). The measurement of the credit loss component is equal to the difference between the debt security’s amortized cost basis and the present value of its expected future cash flows discounted at the security’s effective yield. If the Company intends to sell the security, or if it is more likely than not it will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the amortized cost basis and fair value of the security. The Bank, as a member of the FHLB is required to maintain an investment in the stock of the FHLB. No market exists for this stock, and the Bank’s investment can be liquidated only through redemption by the FHLB, at the discretion of and subject to conditions imposed by the FHLB. Historically, FHLB stock redemptions have been at cost (par value), which equals the Company’s carrying value. The Company monitors its investment in FHLB stock for impairment through review of recent financial results of the FHLB including capital adequacy and liquidity position, dividend payment history, redemption history and information from credit agencies. The Company has not identified any indicators of impairment of FHLB stock.
Loans	Loans The Company’s accounting methods for loans differ depending on whether the loans are new (“New” loans) or acquired (“Acquired” loans), and for acquired loans, whether the loans were acquired at a discount as a result of credit deterioration since the date of origination.
New Loans	New Loans The Company accounts for originated loans and purchased loans not acquired through business acquisitions as new loans. New loans that management has the intent and ability to hold for the foreseeable future are reported at their outstanding principal balances net of any allowance for loan losses, unamortized deferred fees and costs and unamortized premiums or discounts. The net amount of nonrefundable loan origination fees and certain direct costs associated with the lending process are deferred and amortized to interest income over the contractual lives of the new loans using methods which approximate the level yield method. Discounts and premiums are amortized or accreted to interest income over the estimated term of the new loans using methods that approximate the level yield method. Interest income on new loans is accrued based on the unpaid principal balance outstanding and the contractual terms of the loan agreements.
Acquired Loans	Acquired Loans Acquired loans are accounted for under ASC 310-30 unless the loan type is excluded from the scope of ASC 310-30 (i.e. loans where borrowers have revolving privileges at acquisition date, or “Non-ASC 310-30” loans). The Company has elected to account for loans acquired with deteriorated credit quality since origination under ASC 310-30 (“ASC 310-30” loans or pools) due to the following: • There is evidence of credit quality deterioration since origination resulting in a “Day 1” discount attributable, at least in part, to credit quality; • The loans were acquired in a business combination or asset purchase; and • The loans are not to be subsequently accounted for at fair value. The Company has elected this policy for loans acquired through business combinations exhibiting credit deterioration since origination, except those loan types which have been scoped out of ASC 310-30. Substantially all loans acquired through the FDIC-assisted acquisitions had a fair value discount at acquisition date due at least in part to deterioration in credit quality since origination. However, there was a separate grouping of loans individually identified with substantial credit impairment that would be explicitly scoped into ASC 310-30 from those that were classified by analogy. The Company determined that a loan would be explicitly scoped into ASC 310-30 if there was evidence of credit deterioration at Day 1 and that it was probable that the Company would be unable to collect all contractual cash flows receivable. The loans that were classified by analogy were determined to have evidence of credit deterioration at Day 1 and that it was possible, not probable, that the Company would be unable to collect all contractual cash flows receivable. For each acquisition, ASC 310-30 loans are aggregated into pools based on common risk characteristics, which includes similar credit risk of the loans based on whether loans were analogized or were explicitly scoped into ASC 310-30, internal risk ratings for commercial real estate, land and development and commercial loans; and performing status for consumer and single family residential loans. Pools of loans are further aggregated by collateral type (e.g. commercial real estate, single family residential, etc.). The Company did not elect to aggregate loans into pools that were acquired from separate acquisitions completed in the same fiscal quarter. Acquired loans are recorded at their fair value at the acquisition date. Fair value for acquired loans is based on a discounted cash flow methodology that considers factors including the type of loan and related collateral type, delinquency and credit classification status, fixed or variable interest rate, term of loan, whether or not the loan was amortizing, and current discount rates. Additional assumptions used include default rates, loss severity, loss curves and prepayment speeds. Discounts due to credit quality are included in the determination of fair value; therefore an allowance for loan losses is not recorded at the acquisition date. The discount rates used for the cash flow methodology are based on market rates for new originations of comparable loans at the time of acquisition and include adjustments for liquidity concerns. The fair value is determined from the discounted cash flows for each individual loan, and for ASC 310-30 loans are then aggregated at the unit of account, or pool level. For acquired loans with deteriorated credit quality, the Company makes an estimate of the total cash flows it expects to collect from the loans in each pool, which includes undiscounted expected principal and interest as well as cash received through other forms of satisfaction (e.g. foreclosure). The excess of contractual amounts over the total cash flows expected to be collected from the loans is referred to as non-accretable difference, which is not accreted into income. The excess of the expected undiscounted cash flows over the carrying value of the loans is referred to as accretable discount. Accretable discount is recognized as interest income on a level-yield basis over the expected term of the loans in each pool. The Company continues to estimate cash flows expected to be collected over the expected term of the ASC 310-30 loans on a quarterly basis. Subsequent increases in total cash flows expected to be collected are recognized as an adjustment to the accretable discount with the amount of periodic accretion adjusted over the remaining expected term of the loans. Subsequent decreases in cash flows expected to be collected over the expected term of the loans are recognized as impairment in the current period through a provision for loan losses. Each pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. Resolutions of loans may include sales to third parties, receipt of payments in settlement with the borrower, or foreclosure of the collateral. Upon these resolutions, the Company’s policy is to remove an individual ASC 310-30 loan from a pool based on comparing the amount received from its resolution with its contractual amount. Any difference between these amounts is absorbed by the nonaccretable difference. This removal method assumes that the amount received from these resolutions approximates the pool performance expectations of cash flows. The accretable yield percentage is unaffected by the resolution. Any changes in the effective yield for the remaining loans in the pool are addressed by the quarterly cash flow evaluation process for each pool. For loans that are resolved by payment in full, there is no release of the nonaccretable difference for the pool because there is no difference between the amount received at resolution and the contractual amount of the loan. Payments received in excess of expected cash flows may result in an ASC 310-30 pool becoming fully amortized and its carrying value reduced to zero even though outstanding contractual balances remain related to loans in the pool. Once the carrying value of an ASC 310-30 pool is reduced to zero, any future proceeds from the borrower or from the sale of loans are recognized as interest income upon receipt. There were nine ASC 310-30 pools whose carrying value had been reduced to zero as of December 31, 2015. These pools had an aggregate Unpaid Principal Balance (“UPB” or “UPBs”) of $4.5 million as of December 31, 2015. For the year ended December 31, 2015, the Company sold approximately $55.1 million of loans accounted for under ASC 310-30. These sales resulted in proceeds that exceeded the carrying value of the accounting pool in which the loans resided of $11.5 million which was recognized as interest income. Non-ASC 310-30 loans are recorded at their estimated fair value as of the acquisition date and subsequently accounted for under ASC Topic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASC 310-20”). The fair value discount is accreted using methods which approximate the level-yield method over the remaining term of the loans and is recognized as a component of interest income.
Loans Held for Sale	Loans Held for Sale Certain residential fixed rate and adjustable rate mortgage loans originated by the Company with the intent to sell in the secondary market are carried at the lower of cost or fair value, as determined by outstanding commitments from investors. These loans are generally sold on a non-recourse basis with servicing released. Gains and losses on the sale of loans recognized in earnings are measured based on the difference between proceeds received and the carrying amount of the loans, inclusive of deferred origination fees and costs, if any.
Nonaccrual Loans	Nonaccrual Loans For new and Non-ASC 310-30 loans, the Company classifies loans as past due when the payment of principal or interest is greater than 30 days delinquent based on the contractual next payment due date. The Company’s policies related to when loans are placed on nonaccrual status conform to guidelines prescribed by regulatory authorities. 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. Loans secured by one to four family residential properties may remain in accruing status until they are 180 days past due if management determines that it does not have concern over the collectability of principal and interest because the loan is adequately collateralized and in the process of collection. When loans are placed on nonaccrual status, interest receivable is reversed against interest income in the current period and amortization of any discount ceases. Interest payments received thereafter are applied as a reduction to the remaining principal balance unless management believes that the ultimate collection of the principal is likely, in which case payments are recognized in earnings on a cash basis. Loans are removed from nonaccrual status when they become current as to both principal and interest and the collectability of principal and interest is no longer doubtful. Generally, a nonaccrual loan that is restructured remains on nonaccrual for a period of six months to demonstrate the borrower can meet the restructured terms. However, performance prior to the restructuring, or significant events that coincide with the restructuring, are considered in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan remains classified as a nonaccrual loan. Contractually delinquent ASC 310-30 loans are not classified as nonaccrual as long as the discount continues to be accreted on the corresponding ASC 310-30 pool.
Troubled Debt Restructurings	Troubled Debt Restructurings In certain situations due to economic or legal reasons related to a borrower’s financial difficulties, the Company may grant a concession to the borrower for other than an insignificant period of time that it would not otherwise consider. At that time, except for ASC 310-30 loans, which are accounted for as pools, the related loan is classified as a troubled debt restructuring (“TDR”) and considered impaired. Modified ASC 310-30 loans accounted for in pools are not accounted for as TDRs, are not separated from the pools and are not classified as impaired loans. The concessions granted may include rate reductions, principal forgiveness, payment forbearance, extensions of maturity at rates of interest below those commensurate with the risk profile of the borrower, and other actions intended to minimize economic loss. A troubled debt restructured loan is generally placed on nonaccrual status at the time of the modification unless the borrower has no history of missed payments for six months prior to the restructuring. If the borrower performs pursuant to the modified loan terms for at least six months and the remaining loan balance is considered collectible, the loan is returned to accrual status.
Impaired Loans	Impaired Loans An ASC 310-30 pool is considered to be impaired when it is probable that the Company will be unable to collect all the cash flows expected at acquisition, plus additional cash flows expected to be collected arising from changes in estimates after acquisition. All ASC 310-30 pools are evaluated individually for impairment based their expected total cash flows. The discount continues to be accreted on ASC 310-30 pools as long as there are expected future cash flows in excess of the current carrying amount of the pool. Non-ASC 310-30 and new loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. All Non-ASC 310-30 and new loans of $250,000 or greater with an internal risk rating of substandard or below and on nonaccrual, as well as loans classified as TDRs are reviewed individually for impairment on a quarterly basis.
Allowance for Loan Losses	Allowance for Loan Losses The Company’s ALL is established for both performing and nonperforming loans. The Company’s ALL is the amount considered adequate to absorb probable losses within the portfolio based on management’s evaluation of the size and current risk characteristics of the loan portfolio. Such evaluation considers numerous factors including, but not limited to, internal risk ratings, loss forecasts, collateral values, geographic location, borrower FICO scores, delinquency rates, nonperforming and restructured loans, origination channels, product mix, underwriting practices, industry conditions, economic trends and net charge-off trends. The ALL relates to new loans, estimated additional losses arising on Non-ASC 310-30 loans subsequent to the acquisitions and additional impairment recognized as a result of decreases in expected cash flows on ASC 310-30 pools due to further credit deterioration or other factors since the acquisitions. The ALL consists of both specific and general components. For ASC 310-30 pools, a specific valuation allowance is established when it is probable that the Company will be unable to collect all of the cash flows expected at acquisition, plus the additional cash flows expected to be collected arising from changes in estimates after acquisition. Expected cash flows are estimated on an individual loan basis and then aggregated at the ASC 310-30 pool level. The analysis of expected pool cash flows incorporates updated pool level expected prepayment rate, default rate, delinquency level and loss severity given default assumptions. These analyses incorporate information about loan performance, collateral values, the financial condition of the borrower, internal risk ratings, the Company’s own and industry historical delinquency and default severity data. The carrying value for ASC 310-30 pools is reduced by the amount of the calculated impairment, which is also the basis in which future accretion income is calculated. A charge-off is taken for an individual ASC 310-30 loan when it is deemed probable that the loan will be resolved for an amount less than its carrying value. The charge-off is taken to the specific allowance or mark as applicable. Alternatively, an improvement in the expected cash flows related to ASC 310-30 pools results in a reduction or recoupment of any previously established specific allowance with a corresponding credit to the provision for loan losses. Any recoupment recorded is limited to the amount of the remaining specific allowance for that pool, with any excess of expected cash flow resulting in a reclassification from non-accretable to accretable yield and an increase in the prospective yield of the pool. The new and Non-ASC 310-30 loan portfolios have limited delinquency and credit loss history and have not yet exhibited an observable loss trend. The credit quality of loans in these loan portfolios are impacted by delinquency status and debt service coverage generated by the borrowers’ businesses and fluctuations in the value of real estate collateral. Management considers delinquency status to be the most meaningful indicator of the credit quality of one-to-four single family residential, home equity loans and lines of credit and other consumer loans. Delinquency statistics are updated at least monthly. Internal risk ratings are considered the most meaningful indicator of credit quality for Non ASC 310-30 and new commercial, construction, land and development, and commercial real estate loans. Internal risk ratings are a key factor in identifying loans that are individually evaluated for impairment and impact management’s estimates of loss factors used in determining the amount of the ALL. Internal risk ratings are updated on a continuous basis. Relationships with balances in excess of $250,000 are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. New and Non-ASC 310-30 loans of $250,000 or greater with an internal risk rating of substandard or below and on nonaccrual, as well as loans classified as TDR are reviewed individually for impairment on a quarterly basis. The specific allowance established for these loans is based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated market value or the estimated fair value of the underlying collateral less costs of disposition. General allowances are established for new and Non-ASC 310-30 loans that are not evaluated individually for impairment, which are evaluated by loan category based on common risk characteristics. In this process, general loan loss factors are established based on the following: historical loss factors derived from the Federal Financial Institutions Examination Council’s quarterly Unified Performance Branch Report for Group 1 banks (assets greater than $3 billion) using an annualized weighted average eight quarter rolling basis; trends in delinquencies and nonaccruals by loan portfolio segment and asset categories within those segments; portfolio segment and asset category production trends, including average risk ratings and loan-to value (“LTV”) ratios; current industry conditions, including real estate market trends; general economic conditions; credit concentrations by portfolio and asset categories; and portfolio quality, which encompasses an assessment of the quality and relevance of borrowers’ financial information and collateral valuations and average risk rating and migration trends within portfolios and asset categories. Other adjustments for qualitative factors may be made to the allowance after an assessment of internal and external influences on credit quality and loss severity that are not fully reflected in the historical loss or risk rating data. For these measurements, the Company uses assumptions and methodologies that are relevant to estimating the level of impairment and probable losses in the loan portfolio. To the extent that the data supporting such assumptions has limitations, management’s judgment and experience play a key role in recording the allowance estimates. Qualitative adjustments are considered for: portfolio credit quality trends, including levels of delinquency, charge-offs, nonaccrual, restructuring and other factors; policy and credit standards, including quality and experience of lending and credit management; and general economic factors, including national, regional and local conditions and trends. Additions to the ALL are made by provisions charged to earnings. The allowance is decreased by charge-offs of balances no longer deemed collectible. Charge-offs on new and Non-ASC 310-30 loans are recognized as follows: commercial loans are written-off when management determines them to be uncollectible; for unsecured consumer loans at 90 days past due; and for residential real estate loans and secured consumer loans when they become 120 to 180 days past due, depending on the collateral type. The Company reports recoveries on a cash basis at the time received. Recoveries on ASC 310-30 loans that were charged-off and Non-ASC 310-30 loans that were charged-off prior to the Acquisitions are recognized in earnings as income from resolution of acquired assets and do not affect the allowance for loan losses. All other recoveries are credited to the ALL.
Loss Share Indemnification Asset and Clawback Liability	Loss Share Indemnification Asset and Clawback Liability Assets subject to loss sharing agreements with the FDIC are labeled “Covered Assets” in the consolidated financial statements and include acquired loans (“Covered Loans”) and OREO. The loss share indemnification asset is measured separately from the Covered Assets acquired as it is not contractually embedded in any of the Covered Assets. The initial fair value of the loss share indemnification asset represents the present value of the estimated cash payments expected to be received from the FDIC for future losses on Covered Assets, based on the credit adjustment estimated for each Covered Asset and the loss sharing percentages. The estimated cash flows are discounted using a risk-free yield curve plus a premium reflecting the uncertainty related to the timing and receipt of such cash flows. The amount ultimately collected for this asset is dependent upon the performance of the underlying Covered Assets, the passage of time and claims submitted to the FDIC. The amounts covered by the loss sharing agreements are the pre-acquisition book value of the underlying assets, the contractual balance of unfunded commitments that were acquired, and certain future net direct costs applicable to the Covered Assets. As required by the respective loss sharing agreements, the Company submits a loss share certificate to the FDIC on a quarterly basis requesting reimbursement for losses on Covered Assets and covered expenses. Covered expenses are recorded in non-interest expense when incurred with an offsetting increase to the loss share indemnification asset and non-interest income for the amount expected to be reimbursed by the FDIC. Certain covered expenses are claimed upon resolution of the Covered Asset, resulting in the expense and the related reimbursements from the FDIC occurring in different periods. The Company reviews and updates the cash flows expected to be collected on Covered Assets and the FDIC loss share indemnification asset on a quarterly basis as loss and recovery estimates related to Covered Assets change. Decreases in the amount of cash flows expected to be collected on Covered Loans after acquisition result in a provision for loan losses, an increase in the ALL, and a proportional increase to the FDIC loss share indemnification asset and income for the estimated amount to be reimbursed. Increases in the amount of cash flows expected to be collected on Covered Loans after acquisition result in the reversal of any previously-recorded provision for loan losses and related ALL and a decrease to the FDIC loss share indemnification asset, or prospective adjustment to the accretable discount if no provision for loan losses had been previously recorded. If no provision for loan losses had been previously recorded, improvements in the expected cash flows from the Covered Loans, which is reflected as an adjustment to yield and accreted into income over the remaining expected term of the loans, decreases the expected cash flows to be collected from the loss sharing agreement, with such decreases reducing the yield to be accreted on a prospective basis if the total expected cash flows from the loss sharing agreement exceeds its carrying amount; and, if the carrying amount of the FDIC loss share indemnification asset exceeds the total expected cash flows, the excess is amortized as a reduction of income over the shorter of (1) the remaining expected term of the respective loans or (2) the remaining term of the loss sharing agreement. As a result, the value of the FDIC loss share indemnification asset will continue to fluctuate over time based upon the continued performance of the Covered Assets and as the Company receives payments from the FDIC under the loss sharing agreements. The loss sharing agreements between the Company and the FDIC for certain of the Acquisitions include clawback provisions that obligate the Company to pay the FDIC a certain amount in the event that losses incurred by the Company do not reach a specified threshold upon expiration of the loss sharing agreement. The fair value of the clawback liability is initially estimated using the same discounted cash flow model used to determine the loss share indemnification asset, using a discount rate that takes into account the Company’s credit risk. The clawback liability is re-measured quarterly based on the terms of the applicable loss sharing agreement, changes in projected losses on Covered Assets and the cumulative servicing amount, if applicable. The clawback liability is included in other liabilities in the accompanying consolidated balance sheets and the amortization and loss on re-measurement is included in loss share indemnification loss within noninterest income in the accompanying Consolidated Statements of Income. On March 4, 2015, the Bank entered into an agreement with the FDIC to terminate all loss sharing agreements which were entered into in 2010 and 2011 in conjunction with the Bank’s acquisition of substantially all of the assets (“Covered Assets”) and assumption of substantially all of the liabilities of six failed banks in FDIC-assisted acquisitions. Under the early termination, all rights and obligations of the Bank and the FDIC under the loss share agreements, including the clawback provisions, have been eliminated.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation or amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets, except for land which is stated at cost. The useful lives of premises and equipment are: 39 years for bank premises; 3 to 5 years for computer equipment and software; and 5 years for furniture and equipment. Leasehold improvements are amortized on a straight-line basis over the lesser of the lease terms, including certain renewals that were deemed probable at lease inception, or the estimated useful lives of the improvements. Purchased software and external direct costs of computer software developed for internal use are capitalized provided certain criteria are met and amortized over the useful lives of the software. Rent expense and rental income on operating leases are recorded using the straight-line method over the appropriate lease terms.
OREO	OREO Real estate properties acquired through, or in lieu of, foreclosure or in connection with the Acquisitions, are held for sale and are initially recorded at their fair value less disposition costs. When such assets are acquired, any shortfall between the loan carrying value and the estimated fair value of the underlying collateral less disposition costs is recorded as an adjustment to the allowance for loan losses while any excess is recognized in income. The Company periodically performs a valuation of the property held; any excess of carrying value over fair value less disposition costs is charged to earnings as impairment. Routine maintenance and real estate taxes are expensed as incurred.
BOLI	BOLI The Bank owns life insurance policies on certain directors and current and former employees. 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. Increases in the cash surrender value of these policies are included in noninterest income in the Consolidated Statements of Income. The Company’s BOLI policies are invested in general account and hybrid account products that have been underwritten by highly-rated third party insurance carriers.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of consideration transferred in business combinations over the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but is tested for impairment annually or more frequently if events or circumstances indicate that impairment may have occurred. The Company performs its annual goodwill impairment test in the fourth fiscal quarter. The Company has a single reporting unit. The impairment test compares the estimated fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit exceeds its carrying amount, no impairment is indicated. If the fair value of the reporting unit is less than its carrying amount, impairment of goodwill is measured as the excess of the carrying amount of goodwill over its implied fair value. Prior to the issuance of publicly traded stock in August 2014, management used a third party financial institution valuation specialist to estimate the fair value of the reporting unit. This firm employs a market value approach based upon observable market values and price ratios of similar or comparable publicly owned bank holding companies and an investment value approach based upon the projected future value of the Company derived from its financial projections and discounted at an estimated market required cost of capital to estimate the fair value of the Company. Management evaluates and includes a change of control premium in the estimated fair value of the Company for purposes of evaluating goodwill for impairment. Unobservable inputs into the valuation models include the Company’s financial projections and observable inputs include the market values and price ratios of publicly owned bank holding companies and a discount rate based on the capital assets pricing model. Subsequent to August 2014, the Company uses the fair value of the Company’s publicly traded stock to estimate the fair value of the reporting unit. The estimated fair value of the reporting unit at the last impairment testing date exceeded its carrying amount; therefore, no impairment of goodwill was indicated. Core deposit intangible (“CDI”) is a measure of the value of checking and savings deposit relationships acquired in a business combination. The fair value of the CDI stemming from any given business combination is based on the present value of the expected cost savings attributable to the core deposit funding relative to an alternative source of funding. CDI is amortized over the estimated useful lives of the existing deposit relationships acquired, but does not exceed 10 years. The Company evaluates such identifiable intangibles for impairment when events and circumstances indicate that its carrying amount may not be recoverable. If an impairment loss is determined to exist, the loss is reflected as an impairment charge in the Consolidated Statements of Income for the period in which such impairment is identified. No impairment charges were required to be recorded for the years ended December 31, 2015, 2014 or 2013.
Income Taxes	Income Taxes Income tax expense (benefit) is determined using the asset and liability method and consists of income taxes that are currently payable and deferred income taxes. Deferred income tax expense is determined by recognizing deferred tax assets and liabilities for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. Changes in tax rates on deferred tax assets and liabilities are recognized in income in the period that includes the enactment date. A valuation allowance is established for deferred tax assets when management determines that it is more likely than not that some portion or all of a deferred tax asset will not be realized. In making such determinations, the Company considers all available positive and negative evidence that may impact the realization of deferred tax assets. These considerations include the amount of taxable income generated in statutory carryback periods, future reversals of existing taxable temporary differences, projected future taxable income and available tax planning strategies. The Company files a consolidated federal income tax return including the results of its wholly owned subsidiary, the Bank. The Company estimates income taxes payable based on the amount it expects to owe the various tax authorities (i.e., federal and state). Income taxes represent the net estimated amount due to, or to be received from, such tax authorities. In estimating income taxes, management assesses the relative merits and risks of the appropriate tax treatment of transactions, taking into account statutory, judicial, and regulatory guidance in the context of the Company’s tax position. Although the Company uses the best available information to record income taxes, underlying estimates and assumptions can change over time as a result of unanticipated events or circumstances such as changes in tax laws and judicial guidance influencing its overall tax position. An uncertain tax position is recognized only if it is more-likely-than-not to be sustained upon examination, including resolution of any related appeals or litigation process, based on the technical merits of the position. The amount of tax benefit recognized in the financial statements is the largest amount of benefit that is more than fifty percent likely to be sustained upon ultimate settlement of the uncertain tax position. If the initial assessment fails to result in recognition of a tax benefit, the Company subsequently recognizes a tax benefit if there are changes in tax law or case law that raise the likelihood of prevailing on the technical merits of the position to more-likely-than-not, the statute of limitations expires, or there is a completion of an examination resulting in a settlement of that tax year or position with the appropriate agency. The Company recognizes interest related to unrecognized tax benefits in income tax expense (benefit) and penalties, if any, in other operating expenses.
Derivatives	Derivatives The Company accounts for derivative instruments in accordance with FASB ASC Topic 815, “Derivatives and Hedging.” All derivatives are evaluated at inception as to whether or not they are hedging or non-hedging activities, and appropriate documentation is maintained to support the final determination. The Company recognizes all derivatives as either assets or liabilities on the Consolidated Balance Sheets and measures those instruments at fair value. Certain derivative transactions with a particular counterparty, another financial institution, are subject to an enforceable master netting arrangement. The gross liabilities and gross assets to this counterparty are reported on a net basis. Management periodically reviews contracts from various functional areas of the Company to identify potential derivatives embedded within selected contracts. As of December 31, 2015, the Company had interest derivative positions that are not designated as hedging instruments. See Note 9 “Derivatives” for a description of these instruments.
Contingent Consideration Issued to the FDIC	Contingent Consideration Issued to the FDIC In conjunction with certain Acquisitions, the Bank issued contingent consideration to the FDIC in the form of value VAIs and equity appreciation agreements (“EAAs”). Based on their settlement provisions, these instruments are classified as other liabilities in the accompanying Consolidated Balance Sheets and are adjusted to estimated fair value at each financial statement date, with changes in value reflected in other noninterest expenses in the accompanying Consolidated Statements of Income. The fair value of the contingent consideration is based upon projections of the Company’s future estimate value by a third party financial institution valuation specialist. The valuation is based upon the Company’s financial projections and the valuation specialist’s assumptions about the future market valuation of the financial projections derived from historical market price ratios including price to tangible book value and price to earnings. These future projected prices are discounted at a market required equity return derived from the capital asset pricing model. In accordance with the terms of each of the agreements, a range of potential consideration is estimated and a probability is assigned based on management’s judgment to each estimated payment liability to determine a probability weighted expected value. As of December 31, 2015, the Company had no remaining VAIs or EAAs, as the VAIs reached final settlement with the FDIC within the year ended December 31, 2013, and the EAAs reached final settlement with the FDIC on September 29, 2014.
Stock-based Compensation	Stock-based Compensation The Company sponsors an incentive stock option plan established in 2009 (the “2009 Option Plan”) under which options may be granted periodically to key employees and directors of the Company or its affiliates at a specific exercise price to acquire shares of the Company’s Class A common stock. Compensation cost is measured based on the estimated fair value of the award at the grant date and is recognized in earnings on a straight-line basis over the requisite service period. The fair value of stock options is estimated at the date of grant using the Black-Scholes option pricing model. This model requires assumptions as to the expected stock volatility, dividends, terms and risk-free rates. The expected volatility is based on the volatility of comparable peer banks. The expected term represents the period of time that options are expected to be outstanding from the grant date. The risk-free interest rate is based on the US Treasury yield curve in effect at the time of grant for the appropriate life of each option. The expected dividend yield was determined by management based on the expected dividends to be declared over the expected term of the options. In the fourth quarter of 2013, the Company established the 2013 Stock Incentive Plan (the “2013 Incentive Plan”) covering its executive management, directors, individual consultants and employees to receive stock awards for the Company’s common stock. The 2013 Incentive Plan provided that the awards were not exercisable until certain performance conditions were met, which included the completion of an IPO raising at least $100 million (a “Qualified IPO”) or a “Special Transaction”, generally defined as the consummation of a transaction representing a change of control of the Company. On August 6, 2014, the Company completed the initial public offering of 7,520,000 shares of Class A common stock for $22.00 per share. This public offering constituted a “Qualified IPO” with respect to the Company’s Option awards and 2013 Incentive Plan. See Note 15 “Stock-based Compensation and Other Benefit Plans” for further information regarding the 2009 Option Plan and the 2013 Incentive Plan.
Earnings per Share	Earnings per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflect the effect of common stock equivalents, including stock options and unvested shares, calculated using the treasury stock method. Common stock equivalents are excluded from the computation of diluted earnings (loss) per common share in periods in which the effect is anti-dilutive.
Segment Reporting	Segment Reporting The Company operates in one reportable segment of business, Community Banking, which includes the Bank, the Company’s sole banking subsidiary. Through the Bank, the Company provides a broad range of retail and commercial banking services. Management makes operating decisions and assesses performance based on an ongoing review of these banking operations, which constitute the Company’s only operating segment.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists thereby reducing diversity in practice. The amendments in this update became effective for the first quarter ended March 31, 2015. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In January 2014, the FASB issued ASU 2014-04, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” This update defines “in substance repossession or foreclosure” because the diversity in practice regarding when entities were reclassifying loans receivable to other real estate owned. A creditor is considered to have received physical possession (resulting from an in substance repossession or foreclosure) of residential real estate property collateralizing a consumer mortgage loan only upon the occurrence of either of the following: a) The creditor obtains legal title to the residential real estate property upon completion of a foreclosure. A creditor may obtain legal title to the residential real estate property even if the borrower has redemption rights that provide the borrower with a legal right for a period of time after a foreclosure to reclaim the real estate property by paying certain amounts specified by law. b) The borrower conveys all interest in the residential real estate property to the creditor to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The deed in lieu of foreclosure or similar legal agreement is completed when agreed-upon terms and conditions have been satisfied by both the borrower and the creditor. Entities can elect either a prospective or modified retrospective approach to adoption. Under the modified retrospective approach, entities should recognize a cumulative-effect adjustment to residential consumer mortgage loans and foreclosed residential real estate properties existing as of the beginning of the period of adoption. The Company used the prospective approach to adoption. Public entities were required to adopt this update for annual periods and interim periods within those annual periods, beginning after December 15, 2014. All other entities, including emerging growth companies, are required to adopt this update for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 31, 2015. The Company adopted this ASU effective for annual periods beginning after December 15, 2014 and will adopt this ASU for interim periods within the annual periods beginning after December 31, 2015 as the Company qualified as an Emerging Growth Company until December 31, 2015 and had elected to use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act. The adoption of this ASU did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360)—“Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”. The amendments in this update change the definition of a discontinued operation and, thus, limit the circumstances under which a disposal may be reported as a discontinued operation. Under the amendments, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. This ASU was effective for public entities for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. All other entities, including emerging growth companies, are required to adopt this update effective for all occurrences within annual periods beginning on or after December 15, 2014, and interim periods within annual periods beginning on or after December 15, 2015. The Company adopted this ASU effective for all occurrences within the annual period beginning on or after December 15, 2014 and will adopt this ASU for interim periods within the annual periods beginning on or after December 15, 2015 as the Company qualified as an Emerging Growth Company until December 31, 2015 and had elected to use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act. The adoption of this ASU did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (topic 860)—Repurchase-to- Maturity Transactions, Repurchase Financing, and Disclosures”. This update changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The amendments also require two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. Entities must present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The disclosures are not required to be presented for comparative periods before the effective date. For public entities, the accounting-related changes are effective for the first interim or annual period beginning after December 15, 2014. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. For all other entities, included emerging growth companies, the accounting-related changes are effective for annual periods beginning after December 15, 2014 and for interim periods beginning after December 15, 2015, with the option to adopt the requirements for interim periods beginning after December 15, 2014. All additional disclosures are required for annual periods beginning after December 15, 2014 and for interim periods beginning after December 15, 2015. Early adoption is prohibited with the exception that the requirements on accounting-related changes may be adopted for interim periods beginning after December 15, 2014. The Company adopted this ASU effective for annual periods beginning after December 15, 2014 and will adopt for interim periods beginning after December 15, 2015 as the Company qualified as an emerging growth company until December 31, 2015 and had elected to use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act. The adoption of this ASU did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In August 2014, the FASB issued ASU No. 2014-14, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. This update requires that government guaranteed mortgage loans be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. For public entities, this ASU was effective for annual periods and interim periods within those annual periods beginning after December 15, 2014. Prospective or modified-retrospective application is required. For all other entities, including emerging growth companies, this ASU is effective for annual periods ending after December 15, 2015 and interim periods beginning after December 15, 2015. The Company adopted this ASU effective for annual periods ending after December 15, 2015 and will adopt for interim periods beginning after December 15, 2015 as the Company qualified as an emerging growth company until December 31, 2015 and had elected to use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act. The adoption of this ASU did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows.
Recent Issued Accounting Pronouncements	Recent Issued Accounting Pronouncements Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards affecting public companies. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act. As of December 31, 2015, the Company is no longer considered an emerging growth company and therefore will no longer utilize the extended transition period provided in the Securities Act. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, which will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue recognition guidance throughout the Accounting Standards Codification. The amendments in this update affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts, including leases and insurance contracts, are within the scope of other standards. The amendments establish a core principle requiring the recognition of revenue to depict the transfer of promised goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for such goods or services. The amendments also require expanded disclosures concerning the nature, amount, timing and uncertainty of revenues and cash flows arising from contracts with customers. For public entities, the amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In August 2015, the FASB issued ASU No. 2015-14 delaying the effective date of ASU No. 2014-09. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in Update 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Earlier application is permitted only as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period, or an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which an entity first applies the guidance in Update 2014-09. The Company is currently evaluating this guidance to determine the impact on its 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”. This update 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 non-vesting condition that affects the grant-date fair value of an award. Retrospective adoption beginning with the annual period the entity initially adopted the amendments or modified-retrospective application is required. This ASU is effective for annual periods and interim periods beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40)”. This update requires management to evaluate whether there are conditions and events that raise substantial doubt about an entity’s ability to continue as a going concern. The guidance is intended to incorporate into GAAP a requirement that management perform a going concern evaluation similar to the auditor’s evaluation required by standards issued by the Public Company Accounting Oversight Board (“PCAOB”) and American Institute of Certified Public Accountants (“AICPA”). The guidance is effective for all entities for annual periods ending after December 15, 2016 and for annual and interim periods thereafter. Early application is permitted. The Company believes that this ASU will not have a material impact upon adoption. In November 2014, the FASB issued ASU No. 2014-16, “Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or Equity – a consensus of the FASB Emerging Issues Task Force (ASC 815, Derivatives and Hedging)”. This update requires an entity to determine the nature of an instrument by evaluating all economic characteristics and risks of the entire hybrid instrument when determining whether the host is more akin to debit or equity. For public entities, this guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. This pronouncement is not expected not have a material impact on the Company’s statement of financial position or shareholders equity. In February 2015, the FASB issued ASU No. 2015-02, “Amendments to the Consolidated Analysis (ASC 810, Consolidation)” which amends the consolidation requirements of ASC 810 by reducing the number of consolidation models. The guidance places more emphasis on risk of loss when determining a controlling financial interest; reduces the frequency of the application of related-party guidance when determining a controlling financial interest and changes the consolidation requirements of limited partnerships. For public entities, this guidance is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments in this ASU using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption or may apply the amendments retrospectively. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations and cash flows but does not expect the adoption of this ASU to have a material impact on its consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, “Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (ASC 225-20, Extraordinary and Unusual Items)” which eliminates the concept of extraordinary items. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 for all entities. Under the ASU, extraordinary items will no longer be segregated from the results of ordinary operations and presented separately on the consolidated financial statements. The amendments may be applied prospectively or retrospectively to all prior periods. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” which requires an acquirer to 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 this ASU 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. For public entities, this guidance is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The amendments in this ASU should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this ASU with earlier application permitted for financial statements that have not yet been made available for issuance. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.
