BASIS OF PRESENTATION	'
	NOTE 1. BASIS OF PRESENTATION
	General
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all information and notes to the consolidated financial statements necessary for a complete presentation of financial position, results of operations, comprehensive income and cash flows in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in FCB Financial Holdings, Inc.’s (the “Company” or “FCB”) prospectus filed pursuant to Rule 424(b) under the Securities Act (File No. 333-196935) on August 4, 2014 forming part of the Registrant’s Registration Statement on Form S-1, as amended (File No. 333-196935), originally filed on June 20, 2014 (the “Prospectus”). In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or for any other interim period.
	Nature of Operations
	FCB, formerly known as Bond Street Holdings, Inc., is a national bank holding company with one wholly-owned national bank subsidiary, Florida Community Bank, National Association (“Florida Community Bank” or the “Bank), headquartered in Weston, Florida, and provides a full range of banking and related services to individual and corporate customers through 54 banking centers located in Florida at September 30, 2014.
	On June 13, 2014, Bond Street Holdings, Inc. changed its legal name to FCB Financial Holdings, Inc.
	On July 31, 2014, the Securities and Exchange Commission declared effective the Company’s registration statement on Form S-1 registering the shares of the Company’s Class A common stock. The Class A common stock was authorized for trading on the New York Stock Exchange (“NYSE”) under the symbol “FCB.” 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. Of the 7,520,000 shares sold, 4,554,045 shares were sold by the Company and 2,965,955 shares were sold by certain selling shareholders. In addition, on September 3, 2014, the Company sold an additional 720,000 shares of Class A common stock to cover the exercise of the underwriters’ over-allotment option. The Company received net proceeds of approximately $104.5 million from the offering, after deducting the underwriting discounts and commissions of $8.1 million and estimated offering expenses of $3.4 million. The Company did not receive any proceeds from the sale of shares by the selling shareholders.
	On November 7, 2014, FCB Financial Holdings, Inc. filed a registration statement on Form S-1/A registering the resale by the selling stockholders named therein of (i) up to 20,667,727 issued and outstanding shares of the registrant’s Class A Common Stock, par value $0.001 per share (the “Class A Common Stock”), (ii) up to 5,236,234 issued and outstanding shares of the registrant’s Class A Common Stock issuable upon conversion or exchange of currently issued and outstanding shares of the issuer’s Class B Common Stock, par value $0.001 per share (the “Class B Common Stock”), (iii) up to 3,310,428 shares of Class A Common Stock issuable upon the exercise of certain currently outstanding warrants, and (iv) up to an aggregate of 243,499 shares of the registrant’s Class A Common Stock issued pursuant to certain restricted stock unit awards. Pursuant to Rule 416 under the Securities Act of 1933, as amended, this registration statement shall also cover any additional shares of the registrant’s common stock that shall become issuable by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the receipt of consideration that results in an increase in the number of the outstanding shares of the registrant’s common stock. FCB Financial Holdings, Inc. is not selling any shares of common stock and will not receive any proceeds from the sale of the shares by the selling stockholders.
	Reclassifications
	In certain instances, amounts reported in prior periods consolidated financial statements have been reclassified to conform to the current period presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or net income.
	Use of Estimates
	The preparation of financial statements in conformity with U.S GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are susceptible to significant change in the near term are the allowance for credit 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, determination of fair value of financial instruments, valuation of goodwill, intangible assets and other purchase accounting adjustments.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 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:
		•	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.
		•	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.
	The Company is required to adopt this update for annual periods beginning after December 15, 2014, and interim and annual periods thereafter. The update may result in revised disclosures in the Company’s consolidated financial statements but will not have an 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 is effective 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. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. 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 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, and can be applied retrospectively. Early application is not permitted. 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. 2014-11, “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. 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 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 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 nonvesting condition that affects the grant-date fair value of an award. This ASU is effective for fiscal years 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. 2014-14, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. This update requires that government guaranteed mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. This ASU is effective for interim and annual reporting periods beginning after December 15, 2014. The Company is currently evaluating this guidance to determine the impact on its 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.
	Updates to Significant Accounting Policies
	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.

BUSINESS ACQUISITIONS	'
	NOTE 3. BUSINESS ACQUISITIONS
	On January 31, 2014, the Bank acquired all the outstanding common stock in Great Florida Bank (“GFB” or “Great Florida”). 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		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). Federal Home Loan Bank of Atlanta (“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.
	Other Real Estate Owned (“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 $9.2 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. The Company estimates 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 $9.2 million was established against the deferred tax assets associated with Great Florida Bank’s pre-ownership change net operating loss carryforwards.
	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. The goodwill is included within “Goodwill and other intangible assets” in the consolidated balance sheets. None of the goodwill resulting from the Great Florida Bank acquisition is deductible for tax purposes.
	The acquisition of Great Florida Bank is expected to benefit the Company through revenue and expense synergies in addition to the further expansion into the Miami metropolitan area. Management believes the Great Florida Bank acquisition will create opportunities through commercial lending and access to core deposits through a larger branch network.
	The core deposit intangible is being amortized on straight line basis over the estimated life, currently expected to be 10 years.
	For the nine months ended September 30, 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.
	The provisional amounts recorded for the Great Florida Bank acquisition may be updated if better information is obtained about the initial assumptions used to determine fair value amounts 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.

At September 30, 2014, the Company’s security portfolio consisted of 322 securities, of which 150 securities were in an unrealized loss position. A total of 121 were in an unrealized loss position for less than 12 months. The unrealized losses for these securities resulted primarily from changes in interest rates. All securities available for sale at September 30, 2014 and December 31, 2013 are investment grade based on ratings from recognized rating agencies.
The Company monitors its investment securities for other than temporary impairment (“OTTI”). Impairment is evaluated on an individual security basis considering numerous factors, and its relative significance varies depending on the 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 September 30, 2014 or December 31, 2013. The following describes the basis under which the Company has evaluated OTTI:
U.S. Government Agencies and Sponsored Enterprises Obligations and Mortgage-Backed Securities (“MBS”):
The unrealized losses associated with U.S. Government agencies and sponsored enterprises obligations and MBS are primarily driven by changes in interest rates. These securities have either an explicit or implicit U.S. government guarantee.
Corporate Bonds and Asset Backed Securities:
Securities were generally underwritten in accordance with the Company’s own 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 investments 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 own 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.

	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 (“New” loans). The Company classifies loans acquired through business combinations as acquired loans (“Acquired” loans). The acquired loan portfolio is segmented into “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. Approximately 8.0% and 15.9% of total portfolio loans are covered by loss sharing agreements with the FDIC as of September 30, 2014 and December 31, 2013, respectively.

	-2	Balance new loans includes $261.5 million and $155.0 million of owner occupied commercial real estate loans as of September 30, 2014 and December 31, 2013, respectively.
	At September 30, 2014 and December 31, 2013, the unpaid principal balance (“UPB”) of ASC 310-30 loans were $797.8 million and $628.5 million, respectively. At September 30, 2014 and December 31, 2013, the Company had pledged loans as collateral for FHLB advances with a carrying amount of $1.35 billion and $741.9 million, respectively. The recorded investments of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process as of September 30, 2014 totaled $11.1 million. The Company held $478.8 million and $481.0 million of syndicated national loans as of September 30, 2014 and December 31, 2013, respectively.
	During the three and nine months ended September 30, 2014, the Company purchased approximately $156.6 and $227.8 million, respectively, in residential mortgage loans from third parties. During the three and nine months ended September 30, 2013, the Company purchased approximately $29.0 million in residential mortgage loans from a third party.
	During the three months ended September 30, 2014, the Company did not have any residential mortgage loans sold to third parties. During the nine months ended September 30, 2014, the Company sold approximately $23.0 million in residential mortgage loans to a third party. There were no residential mortgage loan sales during the three or nine months ended September 30, 2013.
	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 $19.5 million and $33.7 million in non-accretable difference to accretable discount during the nine months ended September 30, 2014 and 2013, respectively. Changes in accretable discount for ASC 310-30 loans for the nine months ended September 30, 2014 and 2013 were as follows:

Receivables [Abstract]	'
ALLOWANCE FOR LOAN LOSSES ("ALL")	'
	NOTE 6. ALLOWANCE FOR LOAN LOSSES (“ALL”)
	The ALL reflects management’s estimate of probable credit losses inherent in the loan portfolio. The computation of the ALL includes elements of judgment and high levels of subjectivity. Substantially all of the Company’s loans that were acquired in failed bank acquisitions were acquired at a substantial discount to their original book value and are covered by loss sharing agreements with the FDIC.
	The Company’s accounting method for loans and the corresponding ALL differs depending on whether the loans are new or acquired. The Company therefore 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 class the Company further disaggregates the portfolios into the following segments: Commercial real estate, 1-4 single family residential, Construction, land and development, Home equity loans and lines of credit, Commercial and industrial and Consumer.
	Changes in the ALL by loan class and portfolio segment for the three and nine months ended September 30, 2014 and 2013 are as follows:

Credit Quality Indicators
In evaluating credit risk, the Company looks at multiple factors including delinquencies. 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.
The following tables present an aging analysis of the recorded investment for delinquent loans by class and portfolio segment (excluding loans accounted for under ASC 310-30):

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. 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.
The following table summarizes the Company’s Non-ASC 310-30 and New loans by key indicators of credit quality. Loans accounted for under ASC 310-30 are excluded from the following analysis because their related allowance is determined by loan pool performance:

COVERED ASSETS AND LOSS SHARING AGREEMENTS	'
	NOTE 7. COVERED ASSETS AND LOSS SHARING AGREEMENTS
	In each of the 2010 and 2011 Acquisitions (except Sunshine State Community Bank and First Peoples Bank), the Bank and the FDIC entered into loss sharing agreements.
	The following table summarizes the carrying value of assets covered by the loss sharing agreements:
		September 30, 2014			December 31, 2013
		(Dollars in thousands)

	OREO		26,312			27,299
	Total Covered Assets	$	312,728		$	386,554
	When a provision for loan loss is required for a loan subsequent to acquisition 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 statement of income based on the applicable loss sharing ratio. Increases in the loss share indemnification asset of $1.4 million and $4.6 million were included in noninterest income for the nine months ended September 30, 2014 and 2013, respectively, related to the provision for loan losses on Covered Loans, including both ASC 310-30 and Non-ASC 310-30 loans.
	Changes in the loss share indemnification for the periods presented were as follows:
		Three Months Ended						Nine Months Ended

	Balance at end of period	$	69,920		$	96,680		$	69,920		$	96,680
	As of September 30, 2014 and December 31, 2013, the carrying value of loss share indemnification assets exceeded the total cash flow expected to be collected by $37.8 million and $29.8 million, respectively, and is being amortized using the effective interest method over the shorter of (1) the remaining expected term of the respective loans or (2) the remaining term of the loss sharing agreement.
	The following table summarizes the changes in the clawback liability, included in Other Liabilities, for the periods presented:

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
DERIVATIVES	'
	NOTE 10. DERIVATIVES
	The Company is a party to interest rate derivatives that are not designated as hedging instruments. These derivatives relate to interest rate swaps that the Company enters into with customers to allow customers to convert variable rate loans to a fixed rate. The Company pays interest to the customer at a floating rate on the notional amount and receives interest from the customer at a fixed rate for the same notional amount. 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 Company pays the other financial institution interest at the same fixed rate on the same notional amount as the swap entered into with the customer, and receives interest from the financial institution for the same floating rate on the same notional amount. The changes in the fair value of the swaps offset each other, except for any credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss of given default for all counterparties. Any fees received were recognized in earnings at the time of the transaction. The Company recorded $813 thousand and $898 thousand of customer swap fees in noninterest income in the accompanying consolidated statement of income for the three months ended September 30, 2014 and 2013, respectively and $3.0 million and $2.1 million for the nine months ended September 30, 2014 and 2013, respectively.
	All derivative positions held by the Company as of September 30, 2014 were not designated as hedging instruments under ASC 815-10. As of September 30, 2014, 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 three or nine months ended September 30, 2014.
	The following tables summarize the Company’s derivatives outstanding included in “Other Assets” and “Other Liabilities” in the accompanying consolidated balance sheet:

	At September 30, 2014, the Company has pledged investment securities available for sale with a carrying amount of $10.0 million as collateral for these interest rate swaps in a liability position. The amount of collateral required to be posted by the Company varies based on the settlement value of outstanding swaps.
	As of September 30, 2014 and December 31, 2013, substantially all of the floating rate terms within the interest rate contracts held by the Company were indexed to 1-month LIBOR.
	The fair value of the derivative assets and liabilities are included in a table in Note 17 “Fair Value Measurements,” in the line items “Derivative assets” and “Derivative liabilities.”

INCOME TAXES	'
	The effective income tax rate for the three months ended September 30, 2014 was a tax benefit of 2.8%, a decrease of 107.8% compared to the tax expense rate of 35.7% for the three months ended September 30, 2013. This decrease primarily reflects the impact of warrants expense and certain stock-based compensation awards related to the completion of the Company’s initial public offering on August 6, 2014. These warrant and stock-based compensation expenses included $7.0 million of non-deductible expenses that resulted in a change to the Company’s estimated annual tax rate for the year ending December 31, 2014.
	The effective income tax rate for the nine months ended September 30, 2014 was 40.9%, an increase of 16.9% compared to the rate of 35.0% for the nine months ended September 30, 2013. This increase primarily reflects the impact of warrants expense and certain stock-based compensation awards related to the completion of the Company’s initial public offering on August 6, 2014. These warrant and stock-based compensation expenses included $7.0 million of non-deductible expenses that offset the tax-exempt dividend income from preferred stocks and the net gain in cash surrender value of BOLI policies held during the nine months ended September 30, 2014.
	Income tax returns for the tax years ended December 31, 2012, 2011 and 2010 remain subject to examination by the U.S. Federal and various state tax jurisdictions. The Company had no uncertain tax positions at September 30, 2014 or December 31, 2013.

COMMITMENTS AND CONTINGENCIES	'
	NOTE 16. 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, lines of credit and 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 and are subject to the Company’s credit policies. 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. Fees collected on off-balance sheet financial instruments represent the fair value of those commitments and are deferred and amortized over their term, which is typically one year or less. Amounts funded under non-cancelable commitments in effect at the date of acquisition are Covered Assets under the loss-sharing agreements, if applicable, if certain conditions are met.
	Financial Instruments Commitments
	Unfunded credit extension commitments are as follows:
		September 30,		December 31,
		2014		2013
		(Dollars in thousands)
	Commitments to fund loans	$	267,369	$	96,359
	Unused lines of credit		189,215		168,408
	Commercial and standby letters of credit		7,562		4,838
	Total	$	464,146	$	269,605
	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 an extension of credit 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. Those 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.

Fair Value Disclosures [Abstract]	'
FAIR VALUE MEASUREMENTS	'
	NOTE 17. 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 considers assumptions that market participants would use when pricing the asset or liability (observable inputs). When possible, the Company looks to active and observable markets to price identical assets or liabilities and 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 and minimize the use of unobservable inputs. Unobservable inputs are only used 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 a security, 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 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 debt obligations and 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 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. Interest rate derivatives are further described in Note 10 “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 nine months ended September 30, 2014 and 2013, the Company has not realized any losses due to counterparty’s inability to pay any net uncollateralized position. As of September 30, 2014, 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 value appreciation instruments (“VAI”) and equity appreciation agreements (“EAA”). The estimated fair value of 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 September 30, 2014, 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 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.

Financial Instruments Measured at Fair Value on a Non-Recurring Basis
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:
	September 30, 2014		December 31, 2013
	(Dollars in thousands)
Assets that are still held (Level 3):

Negative valuation adjustments:
Impaired loans	$	4	$	—		$	4		$	271
Foreclosed real estate		958		444			1,690			3,351
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 accompanying 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 accompanying statement of income.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments.
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 September 30, 2014 and December 31, 2013, include cash and cash equivalents and due from FDIC.
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 considered various factors, including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing and current discount rates. Loans were grouped together according to similar characteristics and were 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 values 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.
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.
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 liability is determined in accordance with the terms of each agreement. As of September 30, 2014, 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.

Reclassifications	'
	Reclassifications
	In certain instances, amounts reported in prior periods consolidated financial statements have been reclassified to conform to the current period presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or net income.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are susceptible to significant change in the near term are the allowance for credit 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, determination of fair value of financial instruments, valuation of goodwill, intangible assets and other purchase accounting adjustments.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 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:
		•	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.
		•	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.
	The Company is required to adopt this update for annual periods beginning after December 15, 2014, and interim and annual periods thereafter. The update may result in revised disclosures in the Company’s consolidated financial statements but will not have an 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 is effective 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. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. 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 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, and can be applied retrospectively. Early application is not permitted. 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. 2014-11, “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. 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 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 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 nonvesting condition that affects the grant-date fair value of an award. This ASU is effective for fiscal years 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. 2014-14, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. This update requires that government guaranteed mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. This ASU is effective for interim and annual reporting periods beginning after December 15, 2014. The Company is currently evaluating this guidance to determine the impact on its 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.
	Updates to Significant Accounting Policies
	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.
