NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 (“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 audited consolidated financial statements and the notes thereto for FCB Financial Holdings, Inc. (the “Company”) previously filed with the SEC in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. 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 any other interim period.

Nature of Operations

The Company 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 46 banking centers located in Florida at June 30, 2017.

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 acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, acquisition-related fair value computations, stock-based compensation and deferred taxes.

Recently Adopted Accounting Pronouncements

In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This ASU eliminates equity treatment for tax benefits or deficiencies that result from differences between the compensation cost recognized for GAAP purposes and the related tax deduction at settlement or expiration with such changes recognized in income tax expense and excludes excess tax benefits and tax deficiencies from the calculation of assumed proceeds for earnings per share purposes since such amounts are recognized in the income statement. In addition, this ASU simplifies the statements of cash flows by eliminating the bifurcation of excess tax benefits from operating activities to financing activities. The Company recognized approximately $6.7 million and $15.9 million for the three and six months ended June 30, 2017, respectively, of tax benefit in the consolidated statements of income during as a result of the adoption of this guidance that previously would have been recorded in additional paid in capital. The requirement to recognize excess tax benefits and tax deficiencies in the income statement was applied prospectively. This ASU became effective for the first quarter ended March 31, 2017.

7

In March 2016, the FASB issued ASU No. 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments” which clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-stop decision sequence. This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting” which eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this ASU require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

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”). This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

Recently Issued Accounting Pronouncements

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. Under ASU No. 2014-09, revenue should be recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the guidance, an entity should 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when the entity satisfies a performance obligation. 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 ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Because this guidance does not apply to revenue associated with financial instruments, including loans or securities, the new guidance is not expected to have a material impact on the components of income most closely associated with financial instruments, including securities gains/losses and interest income. The Company is currently evaluating this guidance to determine the impact on components of noninterest income. Although management has not completed its evaluation of the impact of adoption of this ASU on noninterest income, management does not expect the amount or timing of the recognition of such revenue to be materially impacted and does not expect adoption to have a material impact on the Company's consolidated financial position, results of operations or cash flows. The Company does not plan to early adopt this guidance and has not yet identified which transition method will be applied upon adoption.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The amendments in this ASU modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019 including any interim periods within that reporting period where goodwill impairment tests are performed. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In Februry 2017, the FASB issued ASU No. 2017-05, "Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) : Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." The FASB is issuing this ASU to clarify the scope of Subtopic 610-20, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets, and to add guidance for partial sales of nonfinancial assets. The amendments in this ASU will require all entities to account for the derecognition of a business or nonprofit activity in accordance with Topic 810. The amendments also eliminate several accounting differences between transactions involving assets and transactions involving businesses. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2017. Public entities may apply the guidance earlier but only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-08, "Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." This ASU shortens the amortization period for certain purchased callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In May 2017, the FASB issued ASU No. 2017-09, "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting." This ASU provides clarity when applying the guidance in Topic 718, specifically relating to a modification of a share-based payment award. Entities should treat changes as modifications unless the fair value, vesting conditions, and classification of the modified awards are unchanged from the conditions immediately before the change. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

At June 30, 2017, the Company’s security portfolio consisted of 372 securities, of which 121 securities were in an unrealized loss position. A total of 99 were in an unrealized loss position for less than 12 months. The unrealized losses for these securities resulted primarily from changes in interest rates and spreads.

The Company monitors its investment securities for other-than-temporary-impairment ("OTTI"). Impairment is evaluated on an individual security basis considering numerous factors, and their relative significance. 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 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 and has determined that no individual security was other-than-temporarily impaired at June 30, 2017. The following describes the basis under which the Company has evaluated OTTI:

11

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 and spreads. These securities were generally underwritten in accordance with the Company’s investment standards prior to the decision to purchase.

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.

NOTE 3. 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. All acquired loans not specifically excluded under ASC 310-30 are accounted for under ASC 310-30. The remaining portfolio of acquired loans excluded under ASC 310-30 are accounted for under ASC 310-20 and are classified as Non-ASC 310-30 loans.

(1) Balance includes $(71) thousand and $3.2 million of net deferred fees, costs, and premium and discount as of June 30, 2017 and December 31, 2016, respectively.

At June 30, 2017 and December 31, 2016, the unpaid principal balance of ASC 310-30 loans were $209.1 million and $231.5 million, respectively. At June 30, 2017 and December 31, 2016, the Company had pledged loans as collateral for FHLB advances of $3.25 billion and $3.20 billion, respectively. The recorded investments of consumer mortgage loans secured by 1-4 family residential real estate properties for which formal foreclosure proceedings are in process as of June 30, 2017 totaled $3.0 million. The Company held $316.9 million and $433.0 million of syndicated national loans as of June 30, 2017 and December 31, 2016.

No loans were purchased during the three and six months ended June 30, 2017 or the three months ended June 30, 2016. The Company purchased approximately $189.2 million of loans from third parties during the six months ended June 30, 2016.

During the three and six months ended June 30, 2017, the Company sold approximately $55.1 million and $192.5 million, respectively, in loans to third parties. During the three and six months ended June 30, 2016, the Company sold approximately $25.6 million and $61.8 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 change in expected cash flows for certain ASC 310-30 loan pools resulted in the reclassification of $(9.6) million and $(19.7) million between non-accretable and accretable discount during the six months ended June 30, 2017 and 2016, respectively.

Changes in accretable discount for ASC 310-30 loans for the six months ended June 30, 2017 and 2016, were as follows:

	Six Months Ended June 30,

NOTE 4. ALLOWANCE FOR LOAN LOSSES

The Company’s accounting method for loans and the corresponding allowance for loan losses (“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.

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.

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.

NOTE 6. 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 $1.9 million and $1.2 million of customer swap fees in noninterest income in the accompanying consolidated statement of income for the three months ended June 30, 2017 and 2016, respectively, and $3.3 million and $2.5 million of customer swap fees in noninterest income in the accompanying consolidated statement of income for the six months ended June 30, 2017 and 2016, respectively.

No credit changes in counterparty credit were identified. There was no change in the fair value of derivative assets and derivative liabilities attributable to credit risk included in noninterest expense in the consolidated statements of income for the three and six months ended June 30, 2017 or 2016.

No derivative positions held by the Company as of June 30, 2017 were designated as hedging instruments under ASC 815-10.

The following tables summarize the Company’s derivatives outstanding included in other assets and other liabilities in the accompanying consolidated balance sheets:

June 30, 2017	Derivative Assets				Derivative Liabilities

NOTE 9. BASIC AND DILUTED EARNINGS PER SHARE

Basic earnings per share (“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 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 EPS in periods in which the effect is anti-dilutive.

28

The following table presents the computation of basic and diluted EPS:

	Three Months Ended June 30,				Six Months Ended June 30,

NOTE 10. INCOME TAXES

The Company uses an estimated annual effective tax rate method in computing its interim tax provision. This effective tax rate is based on forecasted annual pre-tax income, permanent tax differences and statutory tax rates.

The effective tax rates for the three months ended June 30, 2017 and 2016 were 19.2% and 36.8%, respectively. The decrease in the effective tax rate for the second quarter of 2017 was due to the adoption of ASU No. 2016-09 relating to the treatment of excess tax benefits recognized at settlement for share-based payments which resulted in recording a $6.7 million tax benefit in the consolidated statement of income for the quarter ended June 30, 2017 that previously would have been recorded in additional paid in capital. This was partially offset by higher levels of pre-tax income, which is subject to the marginal tax rate and changes in permanent tax differences. The tax rate differs from the statutory rate due to the impact of tax benefits related to bank-owned life insurance, dividends received deductions and certain stock-based compensation awards.

The effective tax rates for the six months ended June 30, 2017 and 2016 were 14.2% and 36.5%, respectively. The decrease in the effective tax rate for the six months ended June 30, 2017 was due to the adoption of ASU No. 2016-09 relating to the treatment of excess tax benefits recognized at settlement for share-based payments which resulted in recording a $15.9 million tax benefit in the consolidated statement of income that previously would have been recorded in additional paid in capital. This was partially offset by higher levels of pre-tax income, which is subject to the marginal tax rate and changes in permanent tax differences. The tax rate differs from the statutory rate due to the impact of tax benefits related to bank-owned life insurance, dividends received deductions and certain stock-based compensation awards.

The fair value of the Awards on the grant date was $4.0 million and will be recognized as compensation expense over the requisite vesting period ending December 31, 2019. The Company recognized $776 thousand of compensation expense during the six months ended June 30, 2017.

2016 Incentive Plan - Restricted Stock Unit Awards

On February 7, 2017, the Compensation Committee granted certain non-employee Directors of the Company a portion of their Directors' compensation for fiscal year 2017 in the form of restricted stock units (the "Directors' RSU Award"). Each RSU constitutes the right to receive from the Company on the date the RSU is settled, one share of Class A Common Stock of the Company. A total of 24,800 Directors' RSUs were granted with a grant date fair value of $1.1 million. Twenty-five percent (25%) of the RSUs vested on each of March 30, 2017 and June 30, 2017, and an additional twenty-five percent (25%) will vest on each of September 30, 2017, and December 31, 2017 provided the participant remains in a continuous service relationship with the Company through such applicable date. Compensation expense will be recognized on a straight-line basis over the requisite vesting period ending December 31, 2017. The Company recognized $560 thousand of compensation expense during the six months ended June 30, 2017.

On March 28, 2017, the Compensation Committee granted a target of 73,144 and a maximum of 91,430 restricted stock units (the "RSU Award") of Class A Common Stock to a certain Executive.

The Company recognized $330 thousand of compensation expense during the six months ended June 30, 2017.

NOTE 12. 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.

31

The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company’s reserve for unfunded commitments totaled $901 thousand as of June 30, 2017 and $1.6 million as of December 31, 2016.

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:

	June 30, 2017		December 31, 2016
	(Dollars in thousands)
Commitments to fund loans	$	745,499	$	724,380
Unused lines of credit	468,433		410,068
Commercial and standby letters of credit	34,082		26,200
Total	$	1,248,014	$	1,160,648

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.

NOTE 13. 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 instruments, or the value of 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.

32

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 if the valuation incorporates primarily observable inputs. Level 2 securities 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 6 “Derivatives.”

For purposes of potential valuation adjustments to our derivative positions, the Company evaluates the credit risk of its counterparties as well as its 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 three and six months ended June 30, 2017 or 2016, the Company has not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. As of June 30, 2017, there were no interest rate derivatives classified as Level 3.

The Company's policy is to recognize transfers into or out of a level of the fair value hierarchy as of the end of the reporting period. There were no transfers of financial assets between levels of the fair value hierarchy during the three and six months ended June 30, 2017.

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 three or six months ended June 30, 2017, 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 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 table shows significant unobservable inputs used in the non-recurring fair value measurement of level 3 assets and liabilities:

Level 3 Assets:	June 30, 2017		December 31, 2016		Valuation Technique	Unobservable Inputs	Range (Weighted Average)
(Dollars in thousands)
Impaired loans	$	7,601	$	8,878	Third party appraisals and discounted cash flows	Collateral discounts and discount rates	0% - 100% (10.2%)
Other real estate owned	18,540		19,228		Third party appraisals	Collateral discounts and estimated cost to sell	10	%

34

The following tables provide information about certain assets measured at fair value on a non-recurring basis:

	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016
	(Dollars in thousands)
Negative valuation adjustments:
Impaired loans	$	207	$	66	$	207	$	66
Other real estate owned	199		805		383		895

Impairment charges resulting from the non-recurring changes in fair value of the 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:

June 30, 2017	Carrying Value		Fair Value		Level 1		Level 2		Level 3

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 June 30, 2017 and December 31, 2016, include cash and cash equivalents.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments. Estimates may differ from actual exit value as defined by ASC 820.

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.

Loans Held for Sale:

Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices.

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.

36

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.

Critical Accounting Policies

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. The more critical accounting estimates and reporting policies include accounting for the ALL, determining fair value of financial instruments, valuation of goodwill and intangible assets, income taxes and the valuation of assets acquired and liabilities assumed in business combinations. Accordingly, the Company’s critical accounting estimates are discussed in detail in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K. The Company’s significant accounting policies and changes in accounting principles and effects of new accounting pronouncements are discussed in detail in Note 1 “Summary of Significant Accounting Policies” in the “Notes to Consolidated Financial Statements” in the Company’s Annual Report on Form 10-K. Additional disclosures regarding the effects of new accounting pronouncements are included in Note 1 “Summary of Significant Accounting Policies” included herein.

Primary Factors Used to Evaluate Our Business

As a financial institution, we manage and evaluate various aspects of both our results of operations and our financial condition. We evaluate the levels and trends of the line items included in our consolidated balance sheets and income statements, as well as various financial ratios that are commonly used in our industry. We analyze these ratios and financial trends against our own historical performance, our budgeted performance and the financial condition and performance of comparable financial institutions in our region and nationally.

Results of Operations

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of interest income on loans receivable, including accretion income on acquired loans, securities and other short-term investments, and interest expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent upon our generation of noninterest income, consisting of income from banking service fees, interest rate swap services, BOLI and recoveries on acquired assets. Other factors contributing to our results of operations include our provisions for loan losses, gains or losses on securities and income taxes, as well as the level of our noninterest expenses, such as compensation and benefits, occupancy and equipment and other miscellaneous operating expenses.

Net Interest Income

Net interest income, a significant contributor to our revenues and net income, represents interest income less interest expense. We generate interest income from interest, dividends and fees received on interest-earning assets, including loans and investment securities. We incur interest expense from interest paid on interest-bearing liabilities, including interest-bearing deposits, and borrowings. To evaluate net interest income, we measure and monitor (1) yields on our loans and other interest-earning assets, (2) the costs of our deposits and other funding sources, (3) our net interest spread, (4) our net interest margin and (5) our provision for loan losses. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as net interest income divided by average interest-earning assets. Because noninterest-bearing sources of funds, such as noninterest-bearing deposits and stockholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these noninterest-bearing sources.

We also recognize income from the accretable discounts associated with the purchase of interest-earning assets. Our acquisitions in 2010 and 2011 and our January 31, 2014 acquisition of Great Florida Bank ("GFB"), produce a portion of our interest income from the accretable discounts on acquired loans. This accretion will continue to have an impact on our net interest income as long as loans acquired with evidence of credit deterioration at acquisition represent a meaningful portion of our interest-earning assets.

Changes in the market interest rates and interest rates we earn on interest-earning assets or pay on interest-bearing liabilities, as well as the volume and types of interest-earning assets, interest-bearing and noninterest-bearing liabilities and stockholders’ equity, are usually the largest drivers of periodic changes in net interest spread, net interest margin and net interest income. In addition, our interest income includes the accretion of the fair value discounts on our acquired loans, which will also affect our net interest spread, net interest margin and net interest income. We measure net interest income before and after the provision for loan losses required to maintain our ALL at acceptable levels.

38

Noninterest Income

Our noninterest income includes the following:

• Service charges and fees;

• Interest rate swap services;

• BOLI income;

• Income from resolution of acquired assets; and

• Net gains and losses from the sale of OREO assets and investment securities

Noninterest Expense

Our noninterest expense includes the following:

• Salaries and employee benefits;

• Occupancy and equipment expenses;

• Other real estate and acquired loan resolution related expenses;

• Professional services;

• Data processing and network expense;

• Regulatory assessments and insurance:

• Marketing and promotions; and

• Amortization of intangibles

Financial Condition

The primary factors we use to evaluate and manage our financial condition include liquidity, asset quality and capital.

Liquidity

We manage liquidity based upon factors that include the amount of core deposits as a percentage of total deposits, the level of diversification of our funding sources, the allocation and amount of our deposits among deposit types, the short-term funding sources used to fund assets, the amount of non-deposit funding used to fund assets, the availability of unused funding sources, off-balance sheet obligations, the availability of assets to be readily converted into cash without undue loss, the amount of cash and liquid securities we hold, and the re-pricing characteristics and maturities of our assets when compared to the re-pricing characteristics of our liabilities, the ability to sell certain pools of assets and other factors.

Asset Quality

We manage the diversification and quality of our assets based upon factors that include the level, distribution, severity and trend of problem, classified, delinquent, nonaccrual, nonperforming and restructured assets, the adequacy of our ALL, discounts and reserves for unfunded loan commitments, the diversification and quality of loan and investment portfolios, the extent of counterparty risks and credit risk concentrations.

Capital

We manage capital based upon factors that include the level and quality of capital and overall financial condition of the Company, the trend and volume of problem assets, the adequacy of discounts and reserves, the level and quality of earnings, the risk exposures in our balance sheet, the levels of Tier 1 (core), risk-based and tangible equity capital, the ratios of Tier 1 (core), risk-based and tangible equity capital to total assets and risk-weighted assets and other factors.

Performance Highlights

Operating and financial highlights for the three months ended June 30, 2017 include the following:

• Net revenue of $80.8 million; $83.0 million on a fully tax equivalent basis

• Reported and Adjusted EPS of $0.76 and $0.71 per share, respectively, on a fully diluted basis

• New loan portfolio grew sequentially at an annualized rate of 25% when excluding the impact of reducing the Syndicated loan portfolio and mortgage sales

• New loan fundings of $536.1 million during the quarter and reduction of Syndicated loan portfolio of $24.9 million

• Demand deposits grew by $125.9 million, or 24% annualized, during the quarter

• Reported and Adjusted efficiency ratio of 43.3% and 42.0%, respectively

• Reported and Adjusted ROA of 147 and 136 basis points, respectively

• Tangible book value per share was $23.88

The reconciliation of certain non-GAAP financial measures, which management believes facilitates the assessment of its banking operations and peer comparability, are included in tabular form under “Non-GAAP Financial Measures”.

Analysis of Results of Operations

The Company reported net income available to common stockholders of $35.1 million, which generated diluted EPS of $0.76 in the second quarter of 2017. Net income available to common stockholders totaled $23.5 million for the second quarter of 2016, which generated diluted EPS of $0.55. The increase in net income was primarily driven by an increase in taxable income of $6.2 million combined with a decrease in income tax expense of $5.4 million. The Company’s results of operations for the second quarter of 2017 produced an annualized return on average assets of 1.47% and an annualized return on average common stockholders’ equity of 12.95% compared to prior year ratios of 1.19% and 10.41%, respectively.

Net Interest Income and Net Interest Margin

Net interest income is the largest component of our income and is affected by the interest rate environment and the volume and composition of interest-earning assets and interest-bearing liabilities. Our interest-earning assets include loans, interest-bearing deposits in other banks and investment securities. Our interest-bearing liabilities include deposits, FHLB advances and other borrowings.

Second Quarter 2017 compared to Second Quarter 2016

Net interest income was $71.9 million for the second quarter of 2017, an increase of $7.0 million compared to $65.0 million for the same period in 2016. The increase in net interest income reflects a $13.4 million increase in interest income partially offset by a $6.4 million increase in interest expense. For the three months ended June 30, 2017, average earning assets increased by $1.70 billion, or 22.9%, compared to the same period of the prior year, while average interest-bearing liabilities increased $1.19 billion, or 19.1%, compared to the three months ended June 30, 2016. The increase in interest income for the second quarter of 2017 was due to a $18.5 million increase in interest income on New loans due to growth in the New loan portfolio and an increase in the average interest rate on New loans. The average balance of New loans increased $1.46 billion and the average interest rate on New loans increased 34 basis points. Interest income on acquired loans decreased $9.6 million for the three months ended June 30, 2017 compared to the second quarter of 2016, primarily due to a decrease in acquired loan resolutions as compared to the prior period. The heightened payoff activity during the second quarter of 2016 increased accretion of acquired loan discounts, resulting in additional interest income and a higher yield. The second quarter of 2017 exhibited a return to normalized paydowns of the acquired loan portfolio, resulting in a lower comparative yield. Interest income on investment securities increased $4.5 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016 primarily due to a $432.7 million, or 27.2%, increase in the average balance combined with a 11 basis point increase in the yield.

Interest expense on deposits increased $5.3 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016 primarily due to a $1.25 billion, or 23.5%, increase in the average balance of interest-bearing deposits combined with a 13 basis point increase in the cost of deposits. Interest expense on savings and money market accounts increased $3.4 million due to a $849.1 million increase in the average balance combined with an increase in rate of 28 basis points. The average rate paid on savings and money market accounts was 0.90% and 0.62% for the three months ended June 30, 2017 and 2016, respectively.

The net interest margin for the three months ended June 30, 2017 was 3.16%, a decrease of 35 basis points compared to 3.51% for the three months ended June 30, 2016. The average yield on interest-earning assets decreased by 19 basis points for the three months ended June 30, 2017 as compared to the three months ended June 30, 2016, combined with the increase in the average rate paid on interest-bearing liabilities of 22 basis points. The decrease in the average yield on interest-earning assets was primarily due to a decrease in acquired loan resolutions as compared to the prior period. The heightened payoff activity during the second quarter of 2016 increased accretion of acquired loan discounts, resulting in additional interest income and a higher yield. The second quarter of 2017 exhibited a return to normalized paydowns of the acquired loan portfolio, resulting in a lower comparative yield.

Six Months of 2017 compared to Six Months of 2016

Net interest income was $141.6 million for the six months ended June 30, 2017, an increase of $12.2 million compared to $129.4 million for the same period in 2016. The increase in net interest income reflects a $22.9 million increase in interest income partially offset by a $10.7 million increase in interest expense. For the six months ended June 30, 2017, average earning assets increased by $1.68 billion, or 23.1%, compared to the same period of the prior year, while average interest-bearing liabilities increased $1.21 billion, or 19.8%, compared to the six months ended June 30, 2016. The increase in interest income for the six months ended June 30, 2017 was due to a $34.5 million increase in interest income on New loans due to growth in the New loan portfolio and an increase in the average interest rate on New loans. The average balance of New loans increased $1.47 billion and the average interest rate on New loans increased 28 basis points. Interest income on acquired loans decreased $20.3 million for the six months ended June 30, 2017 compared to the same period in 2016, primarily due to a decrease in acquired loan resolutions as compared to the prior period. The heightened payoff activity during the six months ended June 30, 2016 increased accretion of acquired loan discounts, resulting in additional interest income and a higher yield. The six months ended June 30, 2017 exhibited a return to normalized paydowns of the acquired loan portfolio, resulting in a lower comparative yield. Interest income on investment securities increased $8.6 million for the six months ended June 30, 2017 compared to the six months ended June 30, 2016 primarily due to a $421.2 million, or 26.6%, increase in the average balance combined with a 12 basis point increase in the yield.

Interest expense on deposits increased $9.5 million for the six months ended June 30, 2017 compared to the six months ended June 30, 2016 primarily due to a $1.32 billion, or 25.7%, increase in the average balance of interest-bearing deposits combined with a 10 basis point increase in the cost of deposits. Interest expense on savings and money market accounts increased $5.7 million due to a $800.7 million increase in the average balance combined with an increase in rate of 23 basis points. The average rate paid on savings and money market accounts was 0.82% and 0.59% for the six months ended June 30, 2017 and 2016, respectively.

43

The net interest margin for the six months ended June 30, 2017 was 3.20%, a decrease of 38 basis points compared to 3.58% for the six months ended June 30, 2016. The average yield on interest-earning assets decreased by 26 basis points for the six months ended June 30, 2017 as compared to the six months ended June 30, 2016, combined with the increase in the average rate paid on interest-bearing liabilities of 17 basis points. The decrease in the average yield on interest-earning assets was primarily due to a decrease in acquired loan resolutions as compared to the prior period. The heightened payoff activity during the six months ended June 30, 2016 increased accretion of acquired loan discounts, resulting in additional interest income and a higher yield. The six months ended June 30, 2017 exhibited a return to normalized paydowns of the acquired loan portfolio, resulting in a lower comparative yield.

Provision for Loan Losses

Second Quarter 2017 compared to Second Quarter 2016

The provision for loan losses is used to maintain the ALL at a level that, in management’s judgment, is appropriate to absorb probable losses inherent in the portfolio at the balance sheet date.

Salaries and employee benefits expenses increased by $1.9 million, or 9.5%, for the second quarter of 2017 compared to the prior year primarily due to an increase in salary and wages of $1.6 million. This was largely the result of increased temporary personnel expense of $1.0 million.

Salaries and employee benefits expenses increased by $3.7 million, or 9.7%, for the six months ended June 30, 2017 compared to the prior year primarily due to an increase in salary and wages of $3.3 million. This was largely the result of increased temporary personnel expense of $2.3 million.

Analysis of Financial Condition

Total assets were $9.90 billion at June 30, 2017, an increase of $811.3 million, or 8.9%, from December 31, 2016. The increase in total assets includes an increase of $613.1 million in net loans, of which New loans increased $640.1 million over the period. Acquired loans decreased by $24.5 million as a result of the run-off of the acquired loan portfolio through receipt of payments, loan payoffs, note sales or resolution through foreclosure and transfers to other real estate owned. The total securities portfolio was $2.11 billion at June 30, 2017, an increase of $186.8 million from December 31, 2016. The remaining increase in total assets was mainly due to increases in cash and due from banks of $9.7 million and interest-earning deposits in other banks of $6.5 million.

Investment Securities

The Company’s investment policy has been established by the Board of Directors and dictates that investment decisions will be made based on, among other things, the safety of the investment, liquidity requirements, interest rate risk, potential returns, cash flow targets and consistency with its asset/liability management policy. The Bank’s Investment Committee is responsible for making investment security portfolio decisions in accordance with the established policies and in coordination with the Board’s Asset/Liability Committee. The Bank’s Investment Committee members, and Bank employees under the direction of such committee, have been delegated authority to purchase and sell securities within specified investment policy guidelines. Portfolio performance and activity are reviewed by the Bank’s Investment Committee and full Board of Directors on a periodic basis.

The Bank’s investment policy provides specific limits on investments depending on a variety of factors, including its asset class, issuer, credit rating, size, maturity, etc. The Bank’s current investment strategy includes maintaining a high credit quality, liquid, diversified portfolio invested in fixed and floating rate securities with short- to intermediate-term maturities. The purpose of this approach is to create a safe and sound investment portfolio that minimizes exposure to interest rate and credit risk while providing attractive relative yields given market conditions.

The Company’s investment securities portfolio primarily consists of U.S. government agencies and sponsored enterprises obligations and agency mortgage-backed securities, corporate debt, asset-backed securities and preferred stocks. Total investment securities totaled $2.11 billion and $1.93 billion as of June 30, 2017 and December 31, 2016, respectively. No securities were determined to be other-than-temporary impaired as of June 30, 2017 or December 31, 2016.

As a member institution of the FHLB and the Federal Reserve Bank (“FRB”), the Bank is required to own capital stock in the FHLB and the FRB. As of June 30, 2017 and December 31, 2016, the Bank held approximately $68.4 million and $51.7 million, respectively, in FHLB and FRB stock. No market exists for this stock, and the Bank’s investment can be liquidated only through repurchase by the FHLB or FRB. Such repurchases have historically been at par value. We monitor our investment in FHLB and FRB stock for impairment through review of recent financial results, dividend payment history and information from credit agencies. As of June 30, 2017 and December 31, 2016, respectively, management did not identify any indicators of impairment of FHLB and FRB stock.

As of June 30, 2017, the effective duration of the Company’s investment portfolio is estimated to be approximately 3.17 years. This estimate is derived using a variety of inputs that are subject to change based on a variety of factors, including but not limited to, changes in interest rates and prepayment speeds.

The average balance of the securities portfolio for the quarter ended June 30, 2017 totaled $2.03 billion with an annualized pre-tax yield of 3.70%.

Except for securities issued by U.S. government agencies and sponsored enterprise obligations, we did not have any concentrations where the total outstanding balances issued by a single issuer exceeded 10% of our stockholders’ equity as of June 30, 2017 or December 31, 2016.

Loan concentration

The current concentrations in our loan portfolio may not be indicative of concentrations in our loan portfolio in the future. We plan to maintain a relatively diversified loan portfolio to help reduce the risk inherent in concentration in certain types of collateral.

During the three and six months ended June 30, 2017, the Company sold approximately $4.6 million and $6.7 million of acquired loans accounted for under ASC 310-30.

Nonaccrual loans totaled $12.6 million at June 30, 2017, a decrease of 51.1% from $25.8 million at December 31, 2016. Excluding acquired loans, nonperforming loans totaled $1.6 million at June 30, 2017, a decrease of $1.0 million from $2.6 million at December 31, 2016.

Nonperforming assets totaled $34.4 million at June 30, 2017, a decrease of $10.7 million, or 23.6%, from December 31, 2016. The decrease is primarily due to the decrease in acquired nonaccrual loans of $12.2 million. Excluding acquired assets, nonperforming assets totaled $1.6 million at June 30, 2017, compared to $2.6 million at December 31, 2016.

49

Our policies related to when loans are placed on nonaccrual status conform to guidelines prescribed by bank 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. Certain loans past due 90 days or more may remain on accrual status if management determines that it does not have concern over the collectability of principal and interest because the loan is secured by assets with a value in excess of the amounts owed and is in the process of collection. Loans are removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest.

Loans accounted for under ASC 310-30 that are delinquent and/or on nonaccrual status continue to accrue income provided the respective pool in which those assets reside maintains a discount and recognizes accretion income. The aforementioned loans are characterized as performing loans greater than 90 days past due. If the pool no longer has a discount and accretion income can no longer be recognized, any loan within that pool on nonaccrual status will be classified as nonaccrual for presentation purposes.

Loans are identified for restructuring based on their delinquency status, risk rating downgrade, or at the request of the borrower. Borrowers that are 90 days delinquent and/or have a history of being delinquent, or experience a risk rating downgrade, are contacted to discuss options to bring the loan current, cure credit risk deficiencies, or other potential restructuring options that will reduce the inherent risk and improve collectability of the loan. In some instances, a borrower will initiate a request for loan restructure. The Bank requires borrowers to provide current financial information to establish the need for financial assistance and satisfy applicable prerequisite conditions required by the Bank. The Bank may also require the borrower to enter into a forbearance agreement.

Modification of loan terms may include the following: reduction of the stated interest rate; extension of maturity date or other payment dates; reduction of the face amount or maturity amount of the loan; reduction in accrued interest; forgiveness of past-due interest; or a combination of the above.

Analysis of the Allowance for Loan Losses

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 subjectivity. As a portion of the Company’s loans were acquired in failed bank acquisitions and were purchased at a substantial discount to their original book value, we segregate loans into three buckets when assessing and analyzing the ALL: New loans, Acquired ASC 310-30 loans, Acquired Non-ASC 310-30 loans.

As of June 30, 2017, our New loans have exhibited limited delinquency and credit loss history restricting the establishment of an observable loss trend. Given this lack of sufficient loss history on the new loan portfolio, general loan loss factors are established based on the industry historical loss rates segmented by portfolio and asset categories. The historical loss factors are adjusted to reflect trends in delinquencies and nonaccruals by loan portfolio segment, 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 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.

The ALL increased $3.4 million to $41.3 million at June 30, 2017 from $37.9 million at December 31, 2016, primarily due to the increase in New loans of $641.0 million. The ALL as a percentage of nonperforming assets and the ALL as a percentage of total gross loans was 120.11% and 0.57% as of June 30, 2017, compared to 84.08% and 0.57% at December 31, 2016. The increase in the ALL as a percentage of nonperforming assets was primarily the result of a decrease in nonaccrual loans.

Net charge-offs were $212 thousand for the second quarter of 2017 compared to $265 thousand for the second quarter of 2016. Net charge-offs were 0.01% of average loans on an annualized basis for the second quarter of 2017, compared to 0.02% for the same period in 2016.

Net charge-offs were $321 thousand for the six months ended June 30, 2017 compared to net recoveries of $1.2 million for the same period in 2016. Net charge-offs were 0.00% of average loans on an annualized basis for the six months ended June 30, 2017, compared to net recoveries of 0.08% of average loans for the same period in 2016.

Other Real Estate Owned

The following table shows the composition of other real estate owned as of the periods presented:

	June 30, 2017		December 31, 2016
	(Dollars in thousands)
Commercial real estate	$	3,515	$	4,033
1-4 single family residential	2,394		1,664
Construction, land and development	12,631		13,531
Total	$	18,540	$	19,228

The following table summarizes the activity related to other real estate owned for the periods presented:

	Three Months Ended June 30,						Six Months Ended June 30,
	2017			2016			2017			2016
	(Dollars in thousands)
Balance at beginning of period	$	18,761		$	43,522		$	19,228		$	39,340
Transfers from loan portfolio	506			3,277			1,394			10,622
Impairments	(199		)	(796		)	(383		)	(886		)
Sales	(528		)	(16,713		)	(1,699		)	(19,786		)
Balance at end of period	$	18,540		$	29,290		$	18,540		$	29,290

Total OREO held by the Company was $18.5 million as of June 30, 2017, a decrease of $688 thousand from December 31, 2016. The decrease in other real estate owned was due to OREO sales of $1.7 million during the six months ended June 30, 2017 partially offset by $1.4 million in transfers from the loan portfolio.

We expect that OREO will generally continue to decrease in the future as there will be fewer transfers from the acquired loan portfolio combined with reductions from disposition activity. However, OREO may increase in future periods as a result of future business combinations or changes in economic factors that impact borrowers’ repayment abilities.

Bank-owned Life Insurance

BOLI policies are held in order to insure the key officers and employees of the Bank. Policies are recorded at the cash surrender value adjusted for other charges or other amounts due that are probable at settlement, if applicable.

The following table summarizes the changes in the cash surrender value of BOLI for the periods presented:

	Three Months Ended June 30,					Six Months Ended June 30,
	2017			2016		2017			2016
	(Dollars in thousands)
Balance at beginning of period	$	198,089		$	169,531	$	198,438		$	168,246

Balance at end of period	$	198,250		$	170,817	$	198,250		$	170,817

The company recognized $1.4 million and $1.3 million of BOLI income for the three months ended June 30, 2017 and 2016, resulting in a pre-tax yield of 2.91% and 3.03%, respectively. The company recognized $2.8 million and $2.6 million of BOLI income for the six months ended June 30, 2017 and 2016, resulting in a pre-tax yield of 2.92% and 3.04%, respectively. The total death benefit of the BOLI policies at June 30, 2017 and December 31, 2016 totaled $588.3 million and $591.9 million, respectively.

Deposits

We expect deposits to be our primary funding source in the future as we continue to optimize our deposit mix by continuing to shift our deposit composition from higher cost time deposits to lower cost core deposits.

The following table shows the deposit mix as of the periods presented:

	June 30, 2017				December 31, 2016
	Amount		Percent of Total		Amount		Percent of Total
	(Dollars in thousands)
Noninterest-bearing demand deposits	$	1,135,922	14.8	%	$	905,905	12.4	%
Interest-bearing demand deposits	1,117,280		14.5	%	1,004,452		13.7	%
Interest-bearing NOW accounts	401,845		5.2	%	398,823		5.5	%
Savings and money market accounts	2,970,429		38.6	%	2,780,697		38.1	%
Time deposits	2,069,714		26.9	%	2,215,794		30.3	%
Total deposits	$	7,695,190	100.0	%	$	7,305,671	100.0	%

Total deposits at June 30, 2017 were $7.70 billion, an increase of $389.5 million, or 5.3%, from December 31, 2016. The increase in deposits consisted of a $535.6 million increase in core deposits, partially offset by a $146.1 million decrease in time deposits. Core deposits include demand deposit, NOW accounts, savings and money market accounts and represent 73.1% of total deposits at June 30, 2017, an increase from 69.7% at December 31, 2016.

The increase in core deposits was primarily due to growth in noninterest-bearing demand deposits and savings and money market accounts due to retail marketing efforts and commercial relationship growth. The average rate paid on deposits for the three months ended June 30, 2017 was 0.82%. This represents an increase of 13 basis points as compared to the average rate paid on deposits of 0.69% for the three months ended June 30, 2016. The average rate paid on deposits for the six months ended June 30, 2017 was 0.78%. This represents an increase of 10 basis points as compared to the average rate paid on deposits of 0.68% for the six months ended June 30, 2016.

Borrowings

In addition to deposits, we utilize advances from the FHLB and other borrowings, such as securities sold under repurchase agreements, as a supplementary funding source to finance our operations. FHLB advances are secured by stock, qualifying first residential mortgages, commercial real estate loans, home equity loans and investment securities.

Total borrowings consisted of the following as of the periods presented:

	June 30, 2017		December 31, 2016
	(Dollars in thousands)
FHLB advances	$	944,000	$	592,250

Total contractual outstanding	1,019,401		750,257
Fair value adjustment	93		846
Total borrowings	$	1,019,494	$	751,103

At June 30, 2017, total borrowings were $1.02 billion, an increase of $268.4 million, or 35.7%, from $751.1 million at December 31, 2016. The increase in total borrowings was primarily driven by the $351.8 million increase in FHLB advances partially offset by a decrease in securities sold under repurchase agreements of $84.7 million. The increase in FHLB advances was due to the runoff of brokered deposits.

Short-term borrowings consist of debt with maturities of one year or less and the current portion of long-term debt. The following table is a summary of short-term borrowings for the periods presented:

Capital Resources

Our Company and Bank are subject to regulatory capital adequacy requirements promulgated by federal bank regulatory agencies. Failure by our Company or Bank to meet minimum capital requirements could result in certain mandatory and discretionary actions by regulators that could have a material adverse effect on our consolidated financial statements. The Federal Reserve establishes capital requirements for our Company and the OCC has similar requirements for our Bank. The capital planning process and position is monitored by the Enterprise Risk Committee.

57

Information presented for June 30, 2017, reflects the Basel III capital requirements that became effective January 1, 2015 for both our Company and Bank. Under these capital requirements and the regulatory framework for prompt corrective action, our Company and Bank must meet specific capital guidelines that involve quantitative measures of our Company and Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. Our Company’s and Bank’s capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings and other factors.

Quantitative measures established by regulation require our Company and Bank to maintain certain minimum capital amounts and ratios. Federal bank regulators require our Company and Bank to maintain minimum ratios of core capital to adjusted average assets of 4.0%, common equity tier 1 capital to risk-weighted assets of 4.5%, tier 1 capital to risk-weighted assets of 6.0% and total risk-based capital to risk-weighted assets of 8.0%. Beginning January 1, 2016, Basel III implemented a capital conservation buffer above the minimum risk-based capital requirements in order to avoid certain limitations on capital distributions, stock repurchases and discretionary bonus payments to executive officers. The capital conservation buffer is exclusively composed of common equity tier 1 capital. The capital conservation buffer increases 0.625% annually, beginning January 1, 2016, with the last adjustment occurring in 2019.

The Company and Bank’s regulatory capital ratios, excluding the impact of the capital conservation buffer, are as follows:

At June 30, 2017, our Company and Bank met all the capital adequacy requirements to which they were subject. At June 30, 2017, the Company and Bank were “well capitalized” under the regulatory framework for prompt corrective action. To be “well capitalized,” our Company and Bank must maintain minimum leverage, common equity tier 1 risk-based, tier 1 risk-based and total risk-based capital ratios of at least 5.0%, 6.5%, 8.0% and 10.0%, respectively. Management believes that no conditions or events have occurred since June 30, 2017 that would materially adversely change the Company’s or Bank’s capital classifications. From time to time, we may need to raise additional capital to support our Company’s and Bank’s further growth and to maintain their “well capitalized” status.

The Bank and, with respect to certain provisions, the Company, is also subject to an Order of the FDIC, dated January 22, 2010 (the "Order"), issued in connection with the FDIC’s approval of the Bank’s application for federal deposit insurance. The Order requires, among other things, that the Bank, the Company, our founders and certain of our stockholders comply with all applicable provisions of the FDIC's Statement of Policy on Qualifications for Failed Bank Acquisitions ("SOP") and that the Bank maintain capital levels sufficient to be well capitalized under regulatory standards during the remaining period of ownership of the investors (as defined in the Order) subject to the SOP. As of June 30, 2017 and December 31, 2016, we believe the Company and Bank both had capital levels that exceeded the regulatory guidelines for a “well capitalized” institution.

Liquidity

Liquidity represents the Company’s ability to meet financial commitments through the maturity and sale of existing assets or availability of additional funds. Liquidity risk results from the mismatching of asset and liability cash flows. The Bank’s liquidity needs are primarily met by its cash and securities position, growth in deposits, cash flow from amortizing investment and loan portfolios and borrowings from the FHLB. For additional information regarding our operating, investing, and financing cash flows, see “Consolidated Financial Statements—Consolidated Statements of Cash Flows.”

The Bank has access to additional borrowings through secured FHLB and FRB advances, unsecured borrowing lines from correspondent banks and repurchase agreements. At June 30, 2017, the Company had additional capacity to borrow from the FHLB and FRB of $1.24 billion and $43.9 million, respectively. Also, at June 30, 2017, the Company has unused credit lines with financial institutions of $590.0 million.

We believe the Bank’s cash and liquidity resources generated by operations and deposit growth will be sufficient to satisfy the Bank’s future funding requirements. The Bank’s ongoing liquidity position is monitored by the Asset Liability Committee (“ALCO”) and the Enterprise Risk Committee.

59

As a holding company, we are a corporation separate and apart from our subsidiary, the Bank, and therefore we provide for our own liquidity. Our main sources of funding include equity capital raised in our offerings of equity securities and dividends paid by the Bank, when applicable, and access to capital markets. We believe these sources will be sufficient to fund our capital needs for the foreseeable future. There are regulatory limitations that affect the ability of the Bank to pay dividends to us. See “Dividend Policy” and “Supervision and Regulation—Regulatory Limits on Dividends and Distributions” in our Annual Report on Form 10-K for the year ended December 31, 2016 previously filed with the SEC. Management believes that such limitations will not impact our ability to meet our ongoing short-term cash obligations.

On April 27, 2015, Company approved a stock repurchase program (subsequently modified) under which the Company is authorized to acquire up to an aggregate of $70 million of its Class A Common Stock. Repurchases under the program may be made through open market or privately negotiated transactions at times and in such amounts as management deems appropriate, subject to market conditions, regulatory requirements and other factors. The program does not obligate the Company to repurchase any particular amount of common stock, and may be suspended or discontinued at any time without notice. Shares repurchased under the program will be made using the Company’s own cash resources and are expected to be held as treasury shares. As of June 30, 2017, the Company has repurchased $58.7 million of its Class A Common Stock under the stock repurchase program.

Off Balance Sheet Arrangements

In the normal course of business, we enter into various transactions, which, in accordance with GAAP, are not included in our consolidated balance sheets. We enter into these transactions to meet the financing needs of our customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized on the Bank’s consolidated balance sheets. We have limited off-balance sheet arrangements that have not had or are not reasonably likely to have a current or future material effect on our financial condition, revenues, and expenses, results of operations, liquidity, capital expenditures or capital resources.

We enter 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 our commitments to extend credit are contingent upon customers maintaining specific credit standards until the time of loan funding. We decrease our exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. We assess the credit risk associated with certain commitments to extend credit and establish a liability for probable credit losses. Our reserve for unfunded commitments totaled $901 thousand and $1.6 million as of June 30, 2017 and December 31, 2016, respectively.

Standby letters of credit are written conditional commitments issued by us 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, we would be required to fund the commitment. The maximum potential amount of future payments we could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, we would be entitled to seek recovery from the customer. Our policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

The following table summarizes commitments as of the dates presented:

	June 30, 2017		December 31, 2016
	(Dollars in thousands)
Commitments to fund loans	$	745,499	$	724,380
Unused lines of credit	468,433		410,068
Commercial and standby letters of credit	34,082		26,200
Total	$	1,248,014	$	1,160,648

Management believes that we have adequate liquidity to meet all known contractual obligations and unfunded commitments, including loan commitments over the next twelve months.

Management believes these non-GAAP financial measures provide useful information to management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP. Disclosure of these non-GAAP financial measures is relevant to understanding the capital position and performance of the Company and provides a meaningful base for comparability to other financial institutions. We acknowledge that our non-GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP.

Item 3.        Quantitative and Qualitative Disclosure about Market Risk

As described in more detail in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2016, risk management involves the monitoring and evaluation of interest rate risk, liquidity risk, operational risk, compliance risk and strategic and/or reputation risk. The Company has not experienced any material change in these risks from December 31, 2016 to June 30, 2017. For additional disclosure of our market risks, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 previously filed with the SEC.

Item 4.        Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the Company’s management, including its Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of its “disclosure controls and procedures” (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective.

Internal Control over Financial Reporting

There was no change in the Company’s internal control over financial reporting that occurred during the Company’s last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

63

PART II.     OTHER INFORMATION

Item 1.        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, statements of income or cash flows. See Note 12 “Commitments and Contingencies” in the “Notes to Consolidated Financial Statements.”

Item 1A.        Risk Factors

There have been no material changes in the risk factors disclosed by the Company in its Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC.

On March 14, 2017 and March 15, 2017, each of Kent Ellert, President, Chief Executive Officer and Director, Vincent Tese, Executive Chairman and Director, Les Lieberman, Executive Vice Chairman and Director, Stuart Oran, Secretary and Director, and Directors Alan Bernikow, William Mack and Frederic Salerno, of FCB Financial Holdings, Inc. (the “Company”), established pre-arranged stock trading plans to sell a limited amount of shares of the Company’s Class A common stock, par value $0.001 per share (the “Common Stock”), for personal financial management and planning purposes, designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, and the Company’s trading policies regarding stock transactions by directors, executive officers and other employees (collectively, the “Rule 10b5-1 Plans”).

Under Rule 10b5-1, officers, directors and other individuals who are not in possession of material non-public information may adopt a pre-arranged plan or contract for transactions in company securities under specified conditions and at specified times. Using these 10b5-1 plans, individuals may, among other things, diversify their investment portfolios for financial planning purposes, plan for charitable giving, spread stock trades over an extended period of time to reduce market impact and avoid concerns about transactions occurring at a time when they might possess material non-public information. In accordance with Rule 10b5-1, Messrs. Ellert, Tese, Lieberman, Oran, Bernikow, Mack and Salerno will not have discretion over the transactions under their respective Rule 10b5-1 Plans.

Each of Messrs. Ellert’s, Tese’s and Lieberman’s Rule 10b5-1 Plan allows for the sale of a maximum of 200,000 shares of Common Stock, Mr. Oran’s Rule 10b5-1 Plan allows for the sale of a maximum of 30,000 shares of Common Stock, each of Messrs. Bernikow’s and Mack’s Rule 10b5-1 Plan allows for the sale of a maximum of 50,000 shares of Common Stock and Mr. Salerno’s Rule 10b5-1 Plan allows for the sale of a maximum of 30,000 shares of Common Stock, in each case to be acquired through the exercise of outstanding Company stock options. Transactions under the Rule 10b5-1 Plans may occur on the open market at prevailing market prices or subject to minimum price thresholds specified in the respective Rule 10b5-1 Plan. Each of the Rule 10b5-1 Plans provides for transactions to occur during specified periods between April 2017 and December 2017, depending on the terms of the specific Rule 10b5-1 Plan. Messrs. Ellert, Tese, Lieberman, Oran, Bernikow, Mack and Salerno continue to be subject to the Company’s executive and non-employee director stock ownership guidelines, as applicable, and continue to retain the great majority of the shares of Common Stock beneficially owned by them.

Transactions effected under the Rule 10b5-1 Plans from time to time will be reported to the Securities and Exchange Commission in accordance with applicable securities laws, rules and regulations. The Company does not undertake to report 10b5-1 plans that may be adopted by any officers or directors in the future, or to report any modification or termination of any trading plan, whether or not the plan was publicly announced, except to the extent required by law.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 (“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 audited consolidated financial statements and the notes thereto for FCB Financial Holdings, Inc. (the “Company”) previously filed with the SEC in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. 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 any other interim period.

Nature of Operations

The Company 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 46 banking centers located in Florida at June 30, 2017.

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 acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, acquisition-related fair value computations, stock-based compensation and deferred taxes.

Recently Adopted Accounting Pronouncements

In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This ASU eliminates equity treatment for tax benefits or deficiencies that result from differences between the compensation cost recognized for GAAP purposes and the related tax deduction at settlement or expiration with such changes recognized in income tax expense and excludes excess tax benefits and tax deficiencies from the calculation of assumed proceeds for earnings per share purposes since such amounts are recognized in the income statement. In addition, this ASU simplifies the statements of cash flows by eliminating the bifurcation of excess tax benefits from operating activities to financing activities. The Company recognized approximately $6.7 million and $15.9 million for the three and six months ended June 30, 2017, respectively, of tax benefit in the consolidated statements of income during as a result of the adoption of this guidance that previously would have been recorded in additional paid in capital. The requirement to recognize excess tax benefits and tax deficiencies in the income statement was applied prospectively. This ASU became effective for the first quarter ended March 31, 2017.

In March 2016, the FASB issued ASU No. 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments” which clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-stop decision sequence. This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting” which eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this ASU require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

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”). This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

Recently Issued Accounting Pronouncements

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. Under ASU No. 2014-09, revenue should be recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the guidance, an entity should 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when the entity satisfies a performance obligation. 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 ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Because this guidance does not apply to revenue associated with financial instruments, including loans or securities, the new guidance is not expected to have a material impact on the components of income most closely associated with financial instruments, including securities gains/losses and interest income. The Company is currently evaluating this guidance to determine the impact on components of noninterest income. Although management has not completed its evaluation of the impact of adoption of this ASU on noninterest income, management does not expect the amount or timing of the recognition of such revenue to be materially impacted and does not expect adoption to have a material impact on the Company's consolidated financial position, results of operations or cash flows. The Company does not plan to early adopt this guidance and has not yet identified which transition method will be applied upon adoption.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The amendments in this ASU modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019 including any interim periods within that reporting period where goodwill impairment tests are performed. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In Februry 2017, the FASB issued ASU No. 2017-05, "Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) : Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." The FASB is issuing this ASU to clarify the scope of Subtopic 610-20, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets, and to add guidance for partial sales of nonfinancial assets. The amendments in this ASU will require all entities to account for the derecognition of a business or nonprofit activity in accordance with Topic 810. The amendments also eliminate several accounting differences between transactions involving assets and transactions involving businesses. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2017. Public entities may apply the guidance earlier but only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-08, "Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." This ASU shortens the amortization period for certain purchased callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In May 2017, the FASB issued ASU No. 2017-09, "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting." This ASU provides clarity when applying the guidance in Topic 718, specifically relating to a modification of a share-based payment award. Entities should treat changes as modifications unless the fair value, vesting conditions, and classification of the modified awards are unchanged from the conditions immediately before the change. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

At June 30, 2017, the Company’s security portfolio consisted of 372 securities, of which 121 securities were in an unrealized loss position. A total of 99 were in an unrealized loss position for less than 12 months. The unrealized losses for these securities resulted primarily from changes in interest rates and spreads.

The Company monitors its investment securities for other-than-temporary-impairment ("OTTI"). Impairment is evaluated on an individual security basis considering numerous factors, and their relative significance. 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 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 and has determined that no individual security was other-than-temporarily impaired at June 30, 2017. 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 and spreads. These securities were generally underwritten in accordance with the Company’s investment standards prior to the decision to purchase.

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.

(1) Balance includes $(71) thousand and $3.2 million of net deferred fees, costs, and premium and discount as of June 30, 2017 and December 31, 2016, respectively.

At June 30, 2017 and December 31, 2016, the unpaid principal balance of ASC 310-30 loans were $209.1 million and $231.5 million, respectively. At June 30, 2017 and December 31, 2016, the Company had pledged loans as collateral for FHLB advances of $3.25 billion and $3.20 billion, respectively. The recorded investments of consumer mortgage loans secured by 1-4 family residential real estate properties for which formal foreclosure proceedings are in process as of June 30, 2017 totaled $3.0 million. The Company held $316.9 million and $433.0 million of syndicated national loans as of June 30, 2017 and December 31, 2016.

No loans were purchased during the three and six months ended June 30, 2017 or the three months ended June 30, 2016. The Company purchased approximately $189.2 million of loans from third parties during the six months ended June 30, 2016.

During the three and six months ended June 30, 2017, the Company sold approximately $55.1 million and $192.5 million, respectively, in loans to third parties. During the three and six months ended June 30, 2016, the Company sold approximately $25.6 million and $61.8 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 change in expected cash flows for certain ASC 310-30 loan pools resulted in the reclassification of $(9.6) million and $(19.7) million between non-accretable and accretable discount during the six months ended June 30, 2017 and 2016, respectively.

Changes in accretable discount for ASC 310-30 loans for the six months ended June 30, 2017 and 2016, were as follows:

Allowance for Loan Losses

ALLOWANCE FOR LOAN LOSSES

The Company’s accounting method for loans and the corresponding allowance for loan losses (“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.

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):

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 tables summarize the Company’s commercial 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:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

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 $1.9 million and $1.2 million of customer swap fees in noninterest income in the accompanying consolidated statement of income for the three months ended June 30, 2017 and 2016, respectively, and $3.3 million and $2.5 million of customer swap fees in noninterest income in the accompanying consolidated statement of income for the six months ended June 30, 2017 and 2016, respectively.

No credit changes in counterparty credit were identified. There was no change in the fair value of derivative assets and derivative liabilities attributable to credit risk included in noninterest expense in the consolidated statements of income for the three and six months ended June 30, 2017 or 2016.

No derivative positions held by the Company as of June 30, 2017 were designated as hedging instruments under ASC 815-10.

Earnings Per Share [Abstract]

Basic and Diluted Earnings Per Share

BASIC AND DILUTED EARNINGS PER SHARE

Basic earnings per share (“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 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 EPS in periods in which the effect is anti-dilutive.

The following table presents the computation of basic and diluted EPS:

Income Taxes

INCOME TAXES

The Company uses an estimated annual effective tax rate method in computing its interim tax provision. This effective tax rate is based on forecasted annual pre-tax income, permanent tax differences and statutory tax rates.

The effective tax rates for the three months ended June 30, 2017 and 2016 were 19.2% and 36.8%, respectively. The decrease in the effective tax rate for the second quarter of 2017 was due to the adoption of ASU No. 2016-09 relating to the treatment of excess tax benefits recognized at settlement for share-based payments which resulted in recording a $6.7 million tax benefit in the consolidated statement of income for the quarter ended June 30, 2017 that previously would have been recorded in additional paid in capital. This was partially offset by higher levels of pre-tax income, which is subject to the marginal tax rate and changes in permanent tax differences. The tax rate differs from the statutory rate due to the impact of tax benefits related to bank-owned life insurance, dividends received deductions and certain stock-based compensation awards.

The effective tax rates for the six months ended June 30, 2017 and 2016 were 14.2% and 36.5%, respectively. The decrease in the effective tax rate for the six months ended June 30, 2017 was due to the adoption of ASU No. 2016-09 relating to the treatment of excess tax benefits recognized at settlement for share-based payments which resulted in recording a $15.9 million tax benefit in the consolidated statement of income that previously would have been recorded in additional paid in capital. This was partially offset by higher levels of pre-tax income, which is subject to the marginal tax rate and changes in permanent tax differences. The tax rate differs from the statutory rate due to the impact of tax benefits related to bank-owned life insurance, dividends received deductions and certain stock-based compensation awards.

Commitments and Contingencies

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. The Company’s reserve for unfunded commitments totaled $901 thousand as of June 30, 2017 and $1.6 million as of December 31, 2016.

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:

	June 30, 2017		December 31, 2016
	(Dollars in thousands)
Commitments to fund loans	$	745,499	$	724,380
Unused lines of credit	468,433		410,068
Commercial and standby letters of credit	34,082		26,200
Total	$	1,248,014	$	1,160,648

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.

Fair Value Measurements

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 instruments, or the value of 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 if the valuation incorporates primarily observable inputs. Level 2 securities 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 6 “Derivatives.”

For purposes of potential valuation adjustments to our derivative positions, the Company evaluates the credit risk of its counterparties as well as its 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 three and six months ended June 30, 2017 or 2016, the Company has not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. As of June 30, 2017, there were no interest rate derivatives classified as Level 3.

The Company's policy is to recognize transfers into or out of a level of the fair value hierarchy as of the end of the reporting period. There were no transfers of financial assets between levels of the fair value hierarchy during the three and six months ended June 30, 2017.

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 three or six months ended June 30, 2017, 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 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 table shows significant unobservable inputs used in the non-recurring fair value measurement of level 3 assets and liabilities:

Level 3 Assets:	June 30, 2017		December 31, 2016		Valuation Technique	Unobservable Inputs	Range (Weighted Average)
(Dollars in thousands)
Impaired loans	$	7,601	$	8,878	Third party appraisals and discounted cash flows	Collateral discounts and discount rates	0% - 100% (10.2%)
Other real estate owned	18,540		19,228		Third party appraisals	Collateral discounts and estimated cost to sell	10	%

The following tables provide information about certain assets measured at fair value on a non-recurring basis:

	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016
	(Dollars in thousands)
Negative valuation adjustments:
Impaired loans	$	207	$	66	$	207	$	66

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 June 30, 2017 and December 31, 2016, include cash and cash equivalents.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments. Estimates may differ from actual exit value as defined by ASC 820.

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.

Loans Held for Sale:

Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices.

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.

Accounting Policies [Abstract]

General

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 (“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 audited consolidated financial statements and the notes thereto for FCB Financial Holdings, Inc. (the “Company”) previously filed with the SEC in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. 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 any other interim period.

Nature of Operations

Nature of Operations

The Company 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 46 banking centers located in Florida at June 30, 2017.

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 acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, acquisition-related fair value computations, stock-based compensation and deferred taxes.

Recent Adopted and Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This ASU eliminates equity treatment for tax benefits or deficiencies that result from differences between the compensation cost recognized for GAAP purposes and the related tax deduction at settlement or expiration with such changes recognized in income tax expense and excludes excess tax benefits and tax deficiencies from the calculation of assumed proceeds for earnings per share purposes since such amounts are recognized in the income statement. In addition, this ASU simplifies the statements of cash flows by eliminating the bifurcation of excess tax benefits from operating activities to financing activities. The Company recognized approximately $6.7 million and $15.9 million for the three and six months ended June 30, 2017, respectively, of tax benefit in the consolidated statements of income during as a result of the adoption of this guidance that previously would have been recorded in additional paid in capital. The requirement to recognize excess tax benefits and tax deficiencies in the income statement was applied prospectively. This ASU became effective for the first quarter ended March 31, 2017.

In March 2016, the FASB issued ASU No. 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments” which clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-stop decision sequence. This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting” which eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this ASU require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

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”). This ASU became effective for the first quarter ended March 31, 2017. The adoption of this guidance did not have a material impact on the consolidated financial statements.

Recently Issued Accounting Pronouncements

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. Under ASU No. 2014-09, revenue should be recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the guidance, an entity should 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when the entity satisfies a performance obligation. 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 ASU No. 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Because this guidance does not apply to revenue associated with financial instruments, including loans or securities, the new guidance is not expected to have a material impact on the components of income most closely associated with financial instruments, including securities gains/losses and interest income. The Company is currently evaluating this guidance to determine the impact on components of noninterest income. Although management has not completed its evaluation of the impact of adoption of this ASU on noninterest income, management does not expect the amount or timing of the recognition of such revenue to be materially impacted and does not expect adoption to have a material impact on the Company's consolidated financial position, results of operations or cash flows. The Company does not plan to early adopt this guidance and has not yet identified which transition method will be applied upon adoption.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The amendments in this ASU modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019 including any interim periods within that reporting period where goodwill impairment tests are performed. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In Februry 2017, the FASB issued ASU No. 2017-05, "Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) : Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." The FASB is issuing this ASU to clarify the scope of Subtopic 610-20, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets, and to add guidance for partial sales of nonfinancial assets. The amendments in this ASU will require all entities to account for the derecognition of a business or nonprofit activity in accordance with Topic 810. The amendments also eliminate several accounting differences between transactions involving assets and transactions involving businesses. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2017. Public entities may apply the guidance earlier but only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-08, "Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." This ASU shortens the amortization period for certain purchased callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.
