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, 2017. 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 two wholly-owned subsidiaries: (i) Florida Community Bank, N.A., a national bank (“Florida Community Bank” or the “Bank”); and (ii) Floridian Custody Services, Inc. ("Custody Services"). Florida Community Bank, headquartered in Weston, Florida, offers a comprehensive range of traditional banking products and services to individual and corporate customers through 51 banking centers located in Florida as of September 30, 2018. Custody Services, headquartered in Davie, Florida, provides clearing and custodian services to deposit brokers and their clients.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, Custody Services and Florida Community 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 consolidated 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 May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, which superseded 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. This guidance should be applied to all contracts with customers except those that are within the scope of other standards. This ASU became effective for the quarter ended March 31, 2018. The Company elected to adopt the new guidance under the modified retrospective approach. Since the Company's revenue is comprised primarily of net interest income from financial instruments that are within the scope of other standards, including loans and securities, the new guidance did not have a material impact upon adoption. In addition, the adoption of this guidance did not result in any material changes to the method of revenue recognition on the components of noninterest income. Accordingly, the adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

7

In May 2016, the FASB issued ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The amendments in this ASU affect the guidance in ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU clarify the guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The amendments in this ASU affect the guidance in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” which:

• Requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income.

• Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value.

• Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet.

• Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes.

• Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.

• Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements.

• Clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets.

An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the ASU. This ASU became effective the for the quarter ended March 31, 2018. As of January 1, 2018, the Company had equity securities in a net pre-tax unrealized gain position of $1.6 million for which $1.0 million, the tax effected balance, was reclassified from other comprehensive income to beginning retained earnings at adoption.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of cash flows (Topic 230): Classification of certain cash receipts and cash payments." The objective of this guidance is to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. This ASU addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." The objective of issuing this ASU is to improve the accounting for the income tax consequences of intra-entity

8

transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. This prohibition on recognition is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. As such, the Board decided that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Consequently, the amendments in this guidance eliminate the exception for an intra-entity transfer of an asset other than inventory. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)." The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this ASU do not provide a definition of restricted cash or restricted cash equivalents. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 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. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's 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. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." This ASU improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and makes certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The Company early adopted ASU 2017-12 during the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.”  This ASU seeks to help entities reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 (Tax Reform Act), enacted on December 22, 2017.  ASU 2018-02 was issued in response to concerns regarding current guidance in GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date, even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income, rather than net income, and as a result the stranded tax effects would not reflect the appropriate tax rate.  ASU 2018-02 allows an entity to make a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects, which is the difference between the historical corporate income tax rate of 35.0% and the newly enacted corporate income tax rate of 21.0%.  The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 31, 2018; however, public business entities are allowed to early adopt ASU 2018-02 in any interim period for which the financial statements have not yet been issued.  ASU 2018-02 may be applied either at the beginning of the period (annual or interim) of adoption or retrospectively to each of the period(s) in which the effect of the change in the U.S. federal corporate tax rate in the Tax Reform Act is recognized.  As a result of the re-measurement of the Company's deferred tax assets following the enactment of the Tax Reform Act, accumulated other

9

comprehensive income included $1.7 million of stranded tax effects at December 31, 2017.  The Company early adopted ASU 2018-02 during the quarter ended March 31, 2018 and made the election to reclassify the stranded tax effects from accumulated other comprehensive income to retained earnings at the beginning of the period of adoption.    

Recently Issued Accounting Pronouncements

In January 2018, the FASB issued ASU No. 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842." This ASU provides an optional transition practical expedient to not evaluate under Topic 842, existing or expired land easements that were not previously accounted for as leases under the current leases guidance in Topic 840. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity adopts Topic 842. An entity that does not elect this practical expedient should evaluate all existing or expired land easements in connection with the adoption of the new lease requirements in Topic 842 to assess whether they meet the definition of a lease. The amendments in this guidance affect the amendments in ASU 2016-02, which are not yet effective but may be early adopted. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements in ASU 2016-02. An entity that early adopted Topic 842 should apply the amendments in this ASU upon issuance. Management does not intend to early adopt this guidance. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In June 2018, the FASB issued ASU 2018-07, "Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting." The amendments of this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842): Targeted Improvements." The amendments of this ASU provide another transition method for the adoption of the new leases standard. Currently, entities are required to adopt the new leases standard using a modified retrospective transition method. The amendments of this ASU provide another transition method by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, this ASU also provides lessors a practical expedient to not separate nonlease components from the associated lease component, similar to the expedient provided for lessees. The amendments related to separating components of a contract affect the amendments in ASU 2016-02, which are not yet effective but can be early adopted. For entities that have not adopted Topic 842 before the issuance of this ASU, the effective date and transition requirements for the amendments in this ASU related to separating components of a contract are the same as the effective date and transition requirements in ASU 2016-02. Management does not intend to early adopt this guidance. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." The amendments of this ASU modify the disclosure requirements about recurring or nonrecurring fair value measurements required under Topic 820, Fair Value Measurement, and require additional disclosures related to unrealized gains and losses included in other comprehensive income. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this ASU. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is

10

a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period, for all entities. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

NOTE 2. BUSINESS ACQUISITIONS

On March 1, 2018, the Company acquired 100% of the outstanding common stock of Floridian Community Holdings, Inc., ("Floridian") the parent company of Floridian Community Bank and Floridian Custody Services, Inc. Under the terms of the acquisition, each share of Floridian common stock was converted into 0.4584 shares of FCB Class A common stock at the effective date. A total of 1,754,362 shares of FCB Class A common stock were issued to holders of Floridian common stock. The Company also paid cash of $7 thousand for fractional shares resulting from the application of the exchange ratio. In addition, the Company incurred a liability of $5.2 million related to Floridian's outstanding stock options that were settled in cash subsequent to the acquisition. The Floridian acquisition will (i) expand the Company's business within demographically attractive markets in southeast Florida; (ii) increase the Company's core deposit base, an important funding source; and (iii) provide the opportunity to sell the Company's broad array of products to Floridians' client base, among other benefits. The results of operations were included in the Company's results beginning on March 1, 2018, the date of acquisition. The fair value of the common shares issued as part of the consideration paid for Floridian was determined using the closing price of the Company's common shares on February 28, 2018. Floridian had total assets of $506.8 million, total liabilities of $465.8 million and operated 5 full-service branches in South Florida as of March 1, 2018. Goodwill of $58.3 million was recognized in the transaction. None of the goodwill recognized is expected to be deductible for income tax purposes.

The Company determined that the acquisition of Floridian constituted a business combination as defined by ASC Topic 805, “Business Combinations”. The acquisition was not considered to be a significant business combination. The assets acquired and liabilities assumed were recorded at their fair values on the date of acquisition. Fair values were determined in accordance with the guidance provided in ASC Topic 820, “Fair Value Measurements”. In many cases, the determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change. The Company utilized the assistance of third-party advisors in the determination of fair value for loans, deposits, other real estate owned and deferred tax assets acquired. The Company may incur losses on the acquired loans that are materially different from losses the Company originally projected.

The Company recorded adjustments to the preliminary fair value estimates in the reporting period in which the adjustments were determined. During the nine months ended September 30, 2018, the Company recorded adjustments to the preliminary fair value estimates resulting in a decrease in assets acquired of $858 thousand, liabilities assumed of $1.1 million, and goodwill of $255 thousand. The adjustments were primarily related to a reduction in the estimated fair value of an assumed liability and other receivables. As of September 30, 2018, the Company has finalized its valuation of the Floridian acquisition.

The following table presents a summary of the assets acquired and liabilities assumed in the Floridian acquisition recorded at fair value:

On July 24, 2018, the Company announced the entry into a definitive merger agreement under which it will be acquired by Columbus, Georgia based Synovus Financial Corp. ("Synovus"). Under the terms of the merger agreement, the Company’s shareholders will receive a fixed ratio of 1.055 shares of Synovus common stock for each common share of the Company in an all-stock transaction. The merger agreement has been unanimously approved by both companies’ Boards of Directors and is subject to customary closing conditions, including approval by the shareholders of both companies and by state and federal bank regulators. The Company and Synovus filed notices and applications to obtain the necessary regulatory approvals on August 22, 2018. The Georgia Department of Banking and Finance approvals were received on September 25, 2018.

On October 9, 2018, an action captioned Stephen Bushansky v. FCB Financial Holdings, Inc. et al., Case 1:18-cv-62399-BB, was filed in the United States District Court, Southern District of Florida on behalf of a purported class of FCB’s stockholders against FCB and its current directors. This complaint alleges violations of Sections 14(a) and 20(a) of the Exchange Act. The action seeks, among other things, to enjoin the defendants from consummating the merger until additional information is disclosed to FCB’s stockholders in advance of the FCB special meeting or to rescind the merger or recover damages to the extent the merger is completed.

On October 11, 2018, an action captioned Paul Parshall v. FCB Financial Holdings, Inc. et al., Case 1:18-cv-01570-LPS, was filed in the United States District Court for the District of Delaware on behalf of a purported class of FCB’s stockholders against FCB, its current directors, Synovus and Merger Sub, alleging violations of Sections 14(a) and 20(a) of the Exchange Act. The action seeks, among other things, to cause defendants to disseminate adequate disclosures, to enjoin defendants from consummating the merger, and to rescind the merger or recover damages to the extent the merger is completed. The court has not acted on either of these complaints, and no relief has been granted as of this time.

(1) To allow for improved comparability, prior year presentation has been modified to remove preferred stock and other equity securities in connection with the adoption of ASU 2016-01.

At September 30, 2018, the Company’s security portfolio consisted of 355 securities, of which 245 securities were in an unrealized loss position. A total of 137 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 September 30, 2018. 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.

14

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 were investment grade as of September 30, 2018 and December 31, 2017 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 available for sale debt securities are shown below. The cost of securities sold is based on the specific identification method.

NOTE 4. LOANS, NET

The Company’s loan portfolio consists of New and Acquired loans. The Company classifies originated loans and purchased loans not acquired through business combinations that did not show evidence of credit deterioration as New loans. The Company classifies loans acquired through business combinations and purchased loans acquired outside of a business combination that show evidence of credit deterioration as Acquired loans. Loans acquired with deteriorated credit quality since origination are accounted for under ASC 310-30, unless specifically excluded from the scope of ASC 310-30. The remaining portfolio of Acquired loans and those loans excluded from the scope of ASC 310-30 are accounted for under ASC 310-20 and are classified as Non-ASC 310-30 loans.

At September 30, 2018 and December 31, 2017, the Company had pledged loans as collateral for FHLB advances of $3.44 billion and $3.36 billion, respectively. The recorded investment of consumer mortgage loans, secured by 1-4 family residential real estate properties, for which formal foreclosure proceedings are in process as of September 30, 2018 totaled $4.2 million. The Company held $288.5 million and $289.1 million of syndicated national loans as of September 30, 2018 and December 31, 2017, respectively.

During the three months ended September 30, 2018, the Company purchased no loans from 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 $3,417 thousand and $(2.7) million between non-accretable and accretable discount during the nine months ended September 30, 2018 and 2017, respectively.

Changes in accretable discount for ASC 310-30 loans for the nine months ended September 30, 2018 and 2017, were as follows:

NOTE 5. 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. During the second quarter 2018, the Company released an unallocated allowance for loan loss of $1.5 million, which was recorded in prior year in response to Hurricane Irma.

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 7. DERIVATIVES

The Company uses interest rate swaps to manage interest rate risk related to borrowings that expose the Company to variability in cash flows due to changes in interest rates. The Company entered into LIBOR-based forward interest rate swaps that are designated as cash flow hedges with the objective of limiting the variability of forecasted interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. Changes in the fair value of interest rate swaps designated as cash flow hedging instruments are reported in accumulated other comprehensive income ("AOCI") and subsequently reclassified into interest expense in the same period in which the related interest on the floating-rate borrowings affects earnings.

The Company is also a party to interest rate derivatives that are not designated as hedging instruments. The Company uses interest rate derivative contracts, such as swaps and caps, in the normal course of business to meet the financial needs of its customers. The interest rate swaps that the Company enters into with customers allow the 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 given default of each counterparty. The Company recorded $4.4 million and $1.5 million of derivative contract fees in noninterest income in the accompanying Consolidated Statement of Income for the three months ended September 30, 2018 and 2017, respectively, and $10.8 million and $4.8 million for the nine months ended September 30, 2018 and 2017, respectively.

In addition, the Company has entered into three risk participation agreements. The notional amount of the risk participation agreements sold was $34.3 million as of September 30, 2018. Assuming all underlying third party customers referenced in the swap agreements defaulted at September 30, 2018, there would be an immaterial amount of exposure to the company. These risk participation agreements mature in 2021.

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 or nine months ended September 30, 2018 or 2017.

The following tables summarize the Company’s derivatives outstanding included in other assets and other liabilities in the accompanying Consolidated Balance Sheets:

	(Dollars in thousands)
Derivatives designated as cash flow hedges:
Interest rate contracts - pay fixed, receive floating	1,313	—	Interest on borrowings

During the three or nine months endedSeptember 30, 2018, no derivative positions designated as cash flow hedges were discontinued and none of the gains or losses reported in AOCI were reclassified into earnings as a result of the discontinuance of cash flow hedges or because of the early extinguishment of borrowings.

The derivative transactions entered into with a financial institution are subject to an enforceable master netting arrangement.

The following tables summarize the gross and net fair values of the Company’s derivatives outstanding with this counterparty included in other liabilities in the accompanying Consolidated Balance Sheets:

September 30, 2018	Gross amounts of recognized liabilities		Gross amounts offset in the consolidated balance sheets			Net amounts in the consolidated balance sheets
	(Dollars in thousands)
Offsetting derivative liabilities:
Counterparty A - Interest rate contracts	$	24,648	$	(1,694	)	$	22,954

	(Dollars in thousands)
Offsetting derivative liabilities:
Counterparty A - Interest rate contracts	$	11,833	$	(4,491	)	$	7,342

At September 30, 2018, the Company has pledged investment securities available for sale with a carrying amount of $2.5 million as collateral for the interest rate swaps in a liability position. The amount of collateral required to be posted by the Company varies based on the settlement value of outstanding swaps.

As of September 30, 2018 and December 31, 2017, substantially all of the floating rate terms within the interest rate contracts held by the Company were indexed to 1-month LIBOR.

The fair value of the derivative assets and liabilities are included in a table in Note 14 “Fair Value Measurements,” in the line items “Derivative assets” and “Derivative liabilities.”

NOTE 10. 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:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
	(Dollars in thousands, except share and per share data)
Net income available to common stockholders	$	43,480	$	32,160	$	126,313	$	106,230
Weighted average number of common shares - basic	46,693,707		43,333,947		46,213,176		42,580,426

NOTE 11. 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 September 30, 2018 and 2017 were 23.5% and 30.2%, respectively. The decrease in the effective tax rate for the third quarter of 2018 was primarily due to the Tax Cuts and Jobs Act of 2017 (the "TCJA") which resulted in a reduction in the maximum federal corporate income tax rate from 35% to 21%, effective January 1, 2018. This was partially offset by a decrease in excess tax benefits recognized at settlement for share-based payments which resulted in recording a $168 thousand tax benefit in the Consolidated Statements of Income for the quarter ended September 30, 2018 compared to $2.1 million for the quarter ended September 30, 2017. 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 nine months ended September 30, 2018 and 2017 were 21.7% and 19.8%, respectively. The increase in the effective tax rate for the nine months ended September 30, 2018 was due to a decrease in excess tax benefits recognized at settlement for share-based payments which resulted in recording a $2.9 million tax benefit in the Consolidated Statements of Income for the nine months ended September 30, 2018 compared to $18.0 million for the nine months ended September 30, 2017. This was partially offset by the TCJA which resulted in a reduction in the maximum federal corporate income tax rate effective January 1, 2018, as well as higher levels of pre-tax income.

2016 Incentive Plan - Restricted Stock Unit Awards

On February 21, 2018, the Compensation Committee granted certain non-employee Directors of the Company a portion of their Directors' compensation for fiscal year 2018 in the form of restricted stock units (the "Directors' RSUs"). 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 19,015 Directors' RSUs were granted with a grant date fair value of $1.1 million. Twenty-five percent (25%) of the RSUs vested on both March 31, 2018, June 30, 2018, and September 30, 2018, and an additional twenty-five percent (25%) will vest on December 31, 2018 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, 2018.

On March 21, 2018, the Compensation Committee granted a target of 84,836 and a maximum of 106,043 restricted stock units (the "Executive RSUs") of Class A Common Stock to certain Executives. The total target grant date fair value of the RSU Award was $4.8 million, up to a maximum of $5.9 million, and will be recognized on a straight-line basis as compensation expense over the requisite vesting period ending December 31, 2020.

On five different dates during the period ended September 30, 2018, the Company granted a total of 53,552 restricted shares to employees (the "Employee RSUs") that vest in-full (i.e. cliff vesting) on the 5-year anniversary of the grant date. The fair value of the Awards on the grant date was $3.0 million and will be recognized as compensation expense over the requisite vesting period ending on the respective 5-year anniversary of the Employee RSU Award's grant date.

Executive Incentive Plan

During the year ended December 31, 2015, the Compensation Committee of the Board of Directors of the Company approved the adoption of the FCB Financial Holdings, Inc. Executive Incentive Plan (the “EIP”). The EIP provides for Annual Incentive Awards and Long-Term Incentive Awards, both of which are subject to achievement of specified performance goals.

Long-Term Incentive Awards

On March 21, 2018, the Compensation Committee granted a Long-Term Award of cash phantom units (“CPUs”) under the Long-Term Incentive component of the EIP which covers a three-year period ending December 31, 2020 (the “Performance Period”). Granted under the award is a target of 18,050 CPUs and a maximum of 22,562 CPUs to a certain Executive. Each CPU is the equivalent in value of a share of Class A Common Stock of the Company, par value $0.001 per share. The total target grant date fair value of the CPU Award was $1.0 million, up to a maximum of $1.3 million, and will be recognized on a straight-line basis as compensation expense over the requisite period ending December 31, 2020. The Company recognized $91 thousand and $193 thousand of compensation expense during the three and nine months ended September 30, 2018, respectively.

NOTE 13. 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.

38

The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company’s reserve for unfunded commitments totaled $1.5 million as of September 30, 2018 and $1.1 million as of December 31, 2017.

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:

	September 30, 2018		December 31, 2017
	(Dollars in thousands)
Commitments to fund loans	$	1,159,541	$	926,405
Unused lines of credit	774,695		571,587
Commercial and standby letters of credit	50,945		46,520
Total	$	1,985,181	$	1,544,512

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 14. 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.

39

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.

Derivatives—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, interest rate caps, and risk participation agreements where there is no significant deterioration in the counterparties (loan customers) credit risk since origination of the interest rate swap, interest rate cap, or risk participation agreements. The Company values its interest rate swap, interest rate cap, and risk participation agreement positions using market prices provided by a third party which uses primarily observable market inputs. Derivatives are further described in Note 7 “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 or nine months ended September 30, 2018 and 2017, the Company has not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. As of September 30, 2018, there were no interest rate derivatives classified as Level 3.

The following tables present the assets and liabilities measured at fair value on a recurring basis:

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 or nine months ended September 30, 2018.

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 nine months ended September 30, 2018, 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:	September 30, 2018		December 31, 2017		Valuation Technique	Unobservable Inputs	Range (Weighted Average)
(Dollars in thousands)
Impaired loans	$	28,969	$	6,153	Third party appraisals and discounted cash flows	Collateral discounts and discount rates	0% - 100% (7.1%)
Other real estate owned	10,534		14,906		Third party appraisals	Collateral discounts and estimated cost to sell	10	%

41

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
	(Dollars in thousands)
Negative valuation adjustments:
Impaired loans	$	122	$	—	$	1,715	$	—
Foreclosed real estate	9		54		1,106		437

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 Statements of Income. Impairment charges resulting from the non-recurring changes in fair value of OREO are included in loan and other real estate related expenses in the Consolidated Statements 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:

Certain financial instruments are carried at amounts that approximate fair value due to their short-term nature and generally negligible credit risk. Financial instruments for which fair value approximates the carrying amount at September 30, 2018 and December 31, 2017, 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.

NOTE 15. REVENUE RECOGNITION

On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606)" and all subsequent ASUs that modified Topic 606. As stated in Note 1. "Summary of Significant Accounting Policies", the implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company's historic accounting under Topic 605.

Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with financial guarantees, derivatives, transfers and servicing of loans and lease contracts are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as service charges and deposit related fees, interchange fees, merchant income and sales of other real estate owned. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below.

Service Charges and Fees

Service charges and fees consist of insufficient funds fees, continuous overdraft fees, monthly service charge fees, excessive transaction fees, stop payment fees and other deposit account related fees. Based on the Company's review of the depository contracts and the nature of these fees, the Company grouped the service charges and deposit-related fees embedded in the contracts into two distinct categories, either transactional or non-transactional fees.

Transactional Fees

With respect to transactional fees, the Company recognizes revenue at the time of service. The depository contracts with our customers stipulate that we will continue to provide services until the contract is terminated. Each party can immediately terminate the contract without compensating the other party for the termination (that is, there is no termination penalty). Since the duration of the depository contract doesn’t extend beyond the services already provided because either party can cancel the contract without compensating the other party, the relationship is, in effect, a day-to-day contract. Because the contract doesn’t extend beyond the services performed, the Company recognizes revenue at the time of service as there is no future contract under which to allocate consideration.

Non-Transactional Fees

With respect to monthly non-transactional fees, the Company recognizes revenue each month if it is entitled to the fee because the customer did not meet one of the agreed-upon criteria. Because the contract term does not extend beyond the services already provided (either party can immediately terminate the depository contract without compensating the other party), the Company will not need to make estimates about future monthly fees from a customer. Instead, the Company will recognize revenue for the maintenance fee if the customer does not meet one of the criteria and it would not recognize revenue for the maintenance fee if the customer meets one of the criteria.

Other Noninterest Income

Other noninterest income consists of debit card swipe fees, foreign ATM fees, merchant services revenue, referral income, check printing fees, early withdraw fees, collection fees, wire transfer fees, gain (loss) on sale of other real estate owned, and other miscellaneous fees.

Debit card swipe fees are triggered by cardholder usage and are earned when the customer chooses “debit or credit” at the point of sale. The Bank receives a fee from the network (Interlink, STAR, and PLUS). The VISA international fee is earned when a customer uses a debit card overseas. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Referral fees are earned by either (i) matching a bank customer with a vendor’s credit card where the bank is paid a fee for each approved credit card application, or (ii) refer a customer to a third party for investment services. Check printing fees and other deposit account related fees are

44

largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, when the services are rendered or upon completion.

The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if the Company financing is not at a market rate.

The following table presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the periods presented:

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of September 30, 2018 and December 31, 2017, the Company did not have any significant contract balances.

45

Contract Acquisition Costs

In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.

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.

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 contract services, bank-owned life insurance ("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 and (4) our net interest margin. 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, combined with our January 31, 2014 acquisition of Great Florida Bank ("GFB") and our March 1, 2018 acquisition of Floridian, 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 premiums and 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.

47

Noninterest Income

Our noninterest income includes the following:

• Service charges and fees;

• Interest rate contract 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;

• Loan and other real estate 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, risk-based and tangible equity capital, the ratios of Tier 1, 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 September 30, 2018 include the following:

• Net revenue of $101.4 million; $102.6 million on a fully tax equivalent basis

• Reported and Adjusted EPS of $0.89 and $0.97 per share, respectively, on a fully diluted basis

• New loan portfolio grew sequentially at an annualized rate of 20% excluding syndicated loan paydowns

• New loan fundings of $491.0 million

• Deposits grew sequentially at an annualized rate of 12%

• Reported and Adjusted Efficiency ratio of 41.4% and 37.3%, respectively

• Reported and Adjusted ROA of 1.42% and 1.55%, respectively

• Tangible book value per share was $26.29

48

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 $43.5 million, which generated diluted EPS of $0.89 in the third quarter of 2018. Net income available to common stockholders totaled $32.2 million for the third quarter of 2017, which generated diluted EPS of $0.70. The increase in net income was primarily driven by an increase in taxable income of $10.8 million and by a decrease in income tax expense of $562 thousand. The Company’s results of operations for the third quarter of 2018 produced an annualized return on average assets of 1.42% and an annualized return on average common stockholders’ equity of 12.71% compared to prior year ratios of 1.28% and 11.21%, 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.

Third Quarter 2018 compared to Third Quarter 2017

Net interest income was $92.6 million for the third quarter of 2018, an increase of $16.9 million compared to $75.8 million for the same period in 2017. The increase in net interest income reflects a $32.2 millionincrease in interest income partially offset by a $15.3 millionincrease in interest expense. For the three months ended September 30, 2018, average earning assets increased by $2.07 billion, or 21.8%, compared to the same period of the prior year, while average interest-bearing liabilities

51

increased $1.58 billion, or 20.8%, compared to the three months ended September 30, 2017. The increase in interest income for the third quarter of 2018 was due to a $24.2 millionincrease 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 $1.36 billion and the average interest rate on New loans increased 49 basis points. Interest income on acquired loans increased $3.5 million for the three months ended September 30, 2018 compared to the third quarter of 2017, primarily due to an increase in the acquired loan portfolio partially offset by a decrease in the yield on acquired loans. Interest income on investment securities increased $4.2 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017 primarily due to a $304.3 million, or 14.3%, increase in the average balance combined with a 21 basis point increase in the yield.

Interest expense on deposits increased $16.2 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017 primarily due to a $1.65 billion, or 25.0%increase in the average balance of interest-bearing deposits combined with a 48 basis point increase in the cost of deposits. Interest expense on time deposits increased $11.9 million due to a $1.73 billionincrease in the average balance combined with an increase in rate of 67 basis points. Interest expense on savings and money market accounts increased $2.3 million due to an increase in rate of 44 basis points partially offset by a $248.9 milliondecrease in the average balance. The average rate paid on savings and money market accounts was 1.39% and 0.95% for the three months ended September 30, 2018 and 2017, respectively.

Third Quarter 2018 compared to Third Quarter 2017

The Company reported noninterest income of $8.8 million for the three months ended September 30, 2018, an increase of $339 thousand compared to the three months ended September 30, 2017. The increase was primarily due to an increase of $2.2 million in loan and other fees partially offset by a decrease of $1.2 million in other noninterest income. The increase in loan and other fees was primarily due to an increase in swap fee income of $2.9 million partially offset by a decrease in residential mortgage fee income of $476 thousand. The decrease in other noninterest income was primarily due to a decrease in gain on sale of loans of $1.1 million resulting from lower loan sales volume.

Nine Months of 2018 compared to Nine Months of 2017

The Company reported noninterest income of $23.9 million for the nine months ended September 30, 2018, a decrease of $3.3 million compared to the nine months ended September 30, 2017. The decrease was primarily due to a decrease of $5.0 million in other noninterest income resulting from lower loan sales volume and reduced insurance proceeds combined with a decrease of $3.2 million in gain on investment securities resulting from a decrease in realized gains on available-for-sale securities of $2.1 million combined with $1.1 million in unrealized losses on equity securities. The decrease was partially offset by an increase of $4.9 million in loan and other fees, which resulted from an increase in swap fees over the same time period.

Third Quarter 2018 compared to Third Quarter 2017

The Company reported noninterest expense of $42.3 million for the three months ended September 30, 2018, an increase of $7.1 million, or 20.1%, compared to the three months ended September 30, 2017. The increase for the period was primarily due to increased salaries and employee benefits of $2.2 million combined with an increase in professional services expense of $2.5 million.

Salaries and employee benefits expenses increased by $2.2 million, or 10.4%, for the third quarter of 2018 compared to the prior year primarily due to increased headcount as a result of the Floridian acquisition. Employee wages increased $1.6 million and accrued bonuses increased $1.9 million, partially offset by decreases in temporary personnel expense of $696 thousand and incentive payments of $708 thousand. Professional services expense increased $2.5 million for the third quarter of 2018 compared to the prior year primarily due to increased transaction related expenses for our pending merger.

Nine Months of 2018 compared to Nine Months of 2017

The Company reported noninterest expense of $122.4 million for the nine months ended September 30, 2018, an increase of $16.8 million, or 16.0%, compared to the nine months ended September 30, 2017. The increase for the period was primarily due to increased salaries and employee benefits of $5.9 million, increased professional services expense of $3.1 million, increased data processing and network related expenses of $2.0 million as well as an increase in other operating expenses of $2.0 million.

Salaries and employee benefits expenses increased by $5.9 million or 9.3% for the nine months ended September 30, 2018 compared to the prior year primarily due to increased headcount as a result of the Floridian acquisition. The increase is primarily due to increased employee wages of $5.9 million, increased merger related severance payments of $2.0 million and increased bonus accrual of $1.5 million, partially offset by decreases in temporary personnel expense of $2.8 million and incentive payments of $1.6 million. Professional services expense increased $3.1 million primarily due to increased transaction related expenses for our pending merger. Data processing and network expenses increased $2.0 million, or 21.6%, for the nine months ended September 30, 2018 compared to the prior year primarily due to increased software license expenses of $942 thousand and data conversion costs of $649 thousand. Other operating expenses increased $2.0 million, or 40.2%, for the nine months endedSeptember 30, 2018 compared to the prior year primarily due to an increase in off balance sheet provision expense of $981 thousand.

Provision for Income Taxes

Third Quarter 2018 compared to Third Quarter 2017

The income tax expense for the three months ended September 30, 2018 totaled $13.4 million, a decrease of $562 thousand compared to an income tax expense of $13.9 million for the three months ended September 30, 2017. The decrease in income tax expense was primarily due to a decrease in the effective tax rate for the third quarter of 2018. The effective income tax rate for the three months ended September 30, 2018 was 23.5%, compared to the effective tax rate of 30.2% for the three months ended September 30, 2017. The decrease in the effective tax rate was due to the Tax Cuts and Jobs Act of 2017 (the "TCJA") which resulted in a reduction in the maximum federal corporate income tax rate from 35% to 21%, effective January 1, 2018. This was partially offset by a decrease in excess tax benefits recognized at settlement for share-based payments which resulted in recording a $168 thousand tax benefit in the Consolidated Statements of Income for the quarter ended September 30, 2018 compared to $2.1 million for the three months ended September 30, 2017. 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 compared to the prior year. 

Nine Months of 2018 compared to Nine Months of 2017

The income tax expense for the nine months ended September 30, 2018 totaled $35.1 million, an increase of $8.9 million compared to an income tax expense of $26.2 million for the nine months ended September 30, 2017. The increase in income tax expense was primarily due to an increase in the effective tax rate for 2018. The effective income tax rate for the nine months ended September 30, 2018 was 21.7%, compared to the effective tax rate of 19.8% for the nine months ended September 30, 2017. The increase in the effective tax rate was due to a decrease in excess tax benefits recognized at settlement for share-based payments which resulted in recording a $2.9 million tax benefit in the Consolidated Statements of Income for the nine months ended September 30, 2018 compared to $18.0 million for the nine months endedSeptember 30, 2017. This was partially offset by the TCJA which resulted in a reduction in the maximum federal corporate income tax rate effective January 1, 2018, as well as higher levels of pre-tax income.

Analysis of Financial Condition

Total assets were $12.43 billion at September 30, 2018, an increase of $1.76 billion, or 16.4%, from December 31, 2017. The increase in total assets includes an increase of $1.33 billion in net loans, of which New loans increased $968.0 million over the period. Acquired loans increased by $371.0 million as a result of the Floridian acquisition of $425.9 million partially offset by the run-off of the acquired loan portfolio through receipt of payments, loan payoffs, and resolution through foreclosure and transfers to other real estate owned. The total securities portfolio was $2.41 billion at September 30, 2018, an increase of $234.9 million from December 31, 2017. The remaining increase in total assets was mainly due to increases in goodwill and other intangibles of $61.9 million attributable to the Floridian acquisition, interest-earning deposits in other banks of $68.7 million, and bank-owned life insurance of $14.4 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 available for sale debt securities portfolio primarily consists of U.S. government agencies and sponsored enterprises obligations and agency mortgage-backed securities, state and municipal obligations, corporate debt and asset-backed securities. The Company's investment portfolio also includes preferred stock and other equity securities and FHLB and other bank stock. Total investment securities totaled $2.41 billion and $2.18 billion as of September 30, 2018 and December 31, 2017, respectively. No securities were determined to be other-than-temporarily impaired as of September 30, 2018 or December 31, 2017.

As a member institution of the FHLB and the FRB, the Bank is required to own capital stock in the FHLB and the FRB. As of September 30, 2018 and December 31, 2017, the Bank held approximately $65.8 million and $56.9 million, respectively, of such stock. The FAST Act reduced the dividend rate applicable to Reserve Bank depository institution stockholders with total assets of more than $10 billion (large member banks) to the lesser of 6 percent or the most recent 10-year Treasury auction rate prior to the dividend payment. The dividend rate for other member banks remains at 6 percent. Reserve Banks typically pay dividends to member banks in June and December of each year. 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 September 30, 2018 and December 31, 2017, respectively, management did not identify any indicators of impairment of FHLB and FRB stock.

As of September 30, 2018, the effective duration of the Company’s investment portfolio is estimated to be approximately 2.64 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 investment portfolio for the quarter ended September 30, 2018 totaled $2.44 billion with an annualized pre-tax yield of 3.92% during the quarter.

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 September 30, 2018 or December 31, 2017.

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.

Our New loan portfolio increased by 12.6% to $8.63 billion as of September 30, 2018, as compared to $7.66 billion at December 31, 2017.

During the three and nine months ended September 30, 2018, the Company sold approximately $400 thousand of acquired loans accounted for under ASC 310-30. No interest income was recognized from these sales, as well as from other acquired asset resolutions, as proceeds did not exceed the carrying value of the accounting pool in which the loans resided.

real estate owned of $4.4 million. Excluding acquired assets, nonperforming assets totaled $7.3 million at September 30, 2018, compared to $3.3 million at December 31, 2017.

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.

The following table sets forth our asset quality ratios for the periods presented:

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 and Acquired Non-ASC 310-30 loans.

As of September 30, 2018, 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 $6.0 million to $53.1 million at September 30, 2018 from $47.1 million at December 31, 2017, primarily due to the increase in New loans of $968.0 million. The ALL as a percentage of nonperforming assets and the ALL as a percentage of total gross loans was 161.20% and 0.57% as of September 30, 2018, compared to 150.41% and 0.59% at December 31, 2017. The increase in the ALL as a percentage of nonperforming assets was primarily the result of growth in new commercial and industrial loans.

Net recoveries were $357 thousand for the third quarter of 2018 compared to $86 thousand for the third quarter of 2017. Net recoveries were 0.02% of average loans on an annualized basis for the third quarter of 2018, compared to 0.00% for the same period in 2017.

Net recoveries were $201 thousand for the nine months ended September 30, 2018 compared to net charge-offs of $235 thousand for the same period in 2017. Net recoveries were 0.00% and net charge-offs were 0.00% of average loans on an annualized basis for the nine months ended September 30, 2018 and 2017, respectively.

Other Real Estate Owned

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

Balance at end of period	$	10,534		$	17,599		$	10,534		$	17,599

Total OREO held by the Company was $10.5 million as of September 30, 2018, a decrease of $4.4 million from December 31, 2017. The decrease in other real estate owned was primarily due to OREO sales of $3.6 million and impairments of $1.1

66

million during the nine months ended September 30, 2018, partially offset by $266 thousand 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 September 30,				Nine Months Ended September 30,
	2018		2017		2018			2017
	(Dollars in thousands)

Balance at end of period	$	215,421	$	199,672	$	215,421		$	199,672

The company recognized $1.4 million of BOLI income for the three months ended September 30, 2018 and 2017, resulting in a pre-tax yield of 2.70% and 2.88%, respectively. The company recognized $4.2 million of BOLI income for the nine months ended September 30, 2018 and 2017, resulting in a pre-tax yield of 2.71% and 2.91%, respectively. The total death benefit of the BOLI policies at September 30, 2018 and December 31, 2017 totaled $610.3 million and $585.6 million, respectively.

Deposits

We expect deposits to be our primary funding source in the future as we continue to optimize our deposit mix. We will continue to shift our deposit composition from floating higher rate money market deposits to lower cost demand deposits and fixed cost time deposits to lock in rate.

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

	September 30, 2018				December 31, 2017
	Amount		Percent of Total		Amount		Percent of Total
	(Dollars in thousands)
Noninterest-bearing demand deposits	$	1,577,741	15.5	%	$	1,236,685	14.3	%
Interest-bearing demand deposits	1,207,859		11.9	%	1,454,097		16.8	%
Interest-bearing NOW accounts	410,226		4.0	%	363,191		4.2	%
Savings and money market accounts	2,607,093		25.7	%	3,013,237		34.7	%
Time deposits	4,353,196		42.9	%	2,606,717		30.0	%
Total deposits	$	10,156,115	100.0	%	$	8,673,927	100.0	%

Total deposits at September 30, 2018 were $10.16 billion, an increase of $1.48 billion, or 17.1%, from December 31, 2017. The increase in deposits consisted of a $1.75 billionincrease in time deposits partially offset by a $264.3 milliondecrease in core deposits. Core deposits include demand deposit, NOW accounts, savings and money market accounts and represent 57.1% of total deposits at September 30, 2018, a decrease from 70.0% at December 31, 2017.

The overall increase in deposits was primarily due to the Company's promotional efforts on time deposits growth as well as the Floridian acquisition combined with the retail marketing efforts and commercial relationship growth. The average rate paid on deposits for the three months ended September 30, 2018 was 1.36%. This represents an increase of 48 basis points as compared to the average rate paid on deposits of 0.88% for the three months ended September 30, 2017. The average rate paid on deposits

67

for the nine months ended September 30, 2018 was 1.22%. This represents an increase of 40 basis points as compared to the average rate paid on deposits of 0.82% for the nine months ended September 30, 2017.

The following table shows the remaining maturity of time deposits of $100,000 and greater as of the period presented:

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:

Total borrowings	$	825,558	$	749,113

At September 30, 2018, total borrowings were $825.6 million, an increase of $76.4 million, or 10.2%, from $749.1 million at December 31, 2017. The increase in total borrowings was due to the overall growth in the balance sheet.

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:

The Company’s results of operations for the period ended September 30, 2018 produced an annualized return on average assets of 1.42% and an annualized return on average common stockholders’ equity of 12.71% compared to prior year ratios of 1.28% and 11.21%, respectively.

For the nine months ended September 30, 2018, the Company reported net income of $126.3 million, an increase of $20.1 million, compared to a net income of $106.2 million for the nine months ended September 30, 2017. The Company’s results of operations for the period ended September 30, 2018 produced an annualized return on average assets of 1.45% and an annualized return on average common stockholders’ equity of 12.97% compared to prior year ratios of 1.48% and 13.15%, respectively.

Stockholders’ equity totaled $1.38 billion as of September 30, 2018, an increase of $198.3 million from $1.18 billion as of December 31, 2017, primarily driven by stock issued in connection with the acquisition of Floridian of $94.1 million, net income of $126.3 million, and exercises of stock options and warrants, net of shares surrendered for tax withholding, of $6.0 million partially offset by other comprehensive loss of $34.4 million from decreases in the fair value of the investment portfolio due to a rise in market interest rates.

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.

Information presented for September 30, 2018, 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:

September 30, 2018	Actual				Minimum Capital Requirement				Well Capitalized Requirement
(Dollars in thousands)	Amount		Ratio		Amount		Ratio		Amount		Ratio
Company
Tier 1 leverage ratio	$	1,249,237	10.42	%	$	479,502	4.0	%	$	599,377	5.0	%
Common equity tier 1 capital ratio	1,249,237		11.71	%	480,008		4.5	%	693,345		6.5	%
Tier 1 risk-based capital ratio	1,249,237		11.71	%	640,010		6.0	%	853,347		8.0	%
Total risk-based capital ratio	1,303,896		12.22	%	853,347		8.0	%	1,066,684		10.0	%

Tier 1 risk-based capital ratio	1,120,368		10.69	%	628,590		6.0	%	838,121		8.0	%

At September 30, 2018, our Company and Bank met all the capital adequacy requirements to which they were subject. At September 30, 2018, 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 September 30, 2018 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 September 30, 2018 and December 31, 2017, 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 September 30, 2018, the Company had additional capacity to borrow from the FHLB and FRB of $1.40 billion and $30.8 million, respectively. Also, at September 30, 2018, the Company has unused credit lines with financial institutions of $540.0 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.

71

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, 2017 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, the 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 September 30, 2018, 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 $1.5 million and $1.1 million as of September 30, 2018 and December 31, 2017, 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:

	September 30, 2018		December 31, 2017
	(Dollars in thousands)
Commitments to fund loans	$	1,159,541	$	926,405
Unused lines of credit	774,695		571,587
Commercial and standby letters of credit	50,945		46,520
Total	$	1,985,181	$	1,544,512

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

Non-GAAP Financial Measures

The Company views certain non-operating items, including but not limited to merger related and restructuring charges, gain/(loss) on investment securities and their corresponding tax effect, as adjustments to net income. Non-operating adjustments for the third quarter of 2018 include $3.0 million of transaction related expenses for our pending merger, $332 thousand of data processing and system conversion expense, $292 thousand of other operating expense, $36 thousand of severance and salary expense, and $184 thousandloss on investment securities.

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, 2017, 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, 2017 to September 30, 2018. For additional disclosure of our market risks, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 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.

74

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.

75

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 13 “Commitments and Contingencies” and Note 2 "Business Combinations" 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, 2017 filed with the SEC, except for the following risk factors related to the Company's announcement regarding the entry into a definitive merger agreement under which the Company will be acquired by Columbus, Georgia based Synovus Financial Corp. ("Synovus").

Risks Related to the Company's Proposed Merger with Synovus

We may not complete the proposed transaction with Synovus within the time frame we anticipate or at all, which could negatively affect our business, financial results and operations.

On July 23, 2018, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) under which Synovus will acquire all of the outstanding shares of our common stock. The transaction is subject to a number of closing conditions, such as receipt of regulatory approvals and the approval of our stockholders and Synovus shareholders, which may not be received or may take longer than expected. If the transaction is not consummated within the expected time frame, or at all, the Company and its stockholders would not realize the expected benefits of the merger.

The announcement and pendency of the proposed transaction with Synovus could have an adverse effect on our business.

The announcement and pendency of the proposed transaction with Synovus could cause disruptions and create uncertainty surrounding our business, which could affect our relationships with our customers, vendors or employees, regardless of whether the proposed transaction is completed. We could also potentially lose key customers, vendors or employees. In addition, we have directed, and will continue to direct, management resources towards the completion of the proposed transaction, which may divert management’s attention and our resources from ongoing business and operations.

We are also subject to restrictions on the conduct of our business prior to the consummation of the transaction as provided in the Merger Agreement, including, among other things, certain restrictions on our ability to acquire other businesses, sell or transfer our assets, make capital expenditures, amend our organizational documents and incur indebtedness.  These restrictions could result in our inability to respond effectively to competitive pressures, industry developments and future opportunities.

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, 2017. 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 two wholly-owned subsidiaries: (i) Florida Community Bank, N.A., a national bank (“Florida Community Bank” or the “Bank”); and (ii) Floridian Custody Services, Inc. ("Custody Services"). Florida Community Bank, headquartered in Weston, Florida, offers a comprehensive range of traditional banking products and services to individual and corporate customers through 51 banking centers located in Florida as of September 30, 2018. Custody Services, headquartered in Davie, Florida, provides clearing and custodian services to deposit brokers and their clients.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, Custody Services and Florida Community 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 consolidated 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 May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, which superseded 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. This guidance should be applied to all contracts with customers except those that are within the scope of other standards. This ASU became effective for the quarter ended March 31, 2018. The Company elected to adopt the new guidance under the modified retrospective approach. Since the Company's revenue is comprised primarily of net interest income from financial instruments that are within the scope of other standards, including loans and securities, the new guidance did not have a material impact upon adoption. In addition, the adoption of this guidance did not result in any material changes to the method of revenue recognition on the components of noninterest income. Accordingly, the adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In May 2016, the FASB issued ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The amendments in this ASU affect the guidance in ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU clarify the guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The amendments in this ASU affect the guidance in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” which:

• Requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income.

• Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value.

• Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet.

• Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes.

• Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.

• Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements.

• Clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets.

An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the ASU. This ASU became effective the for the quarter ended March 31, 2018. As of January 1, 2018, the Company had equity securities in a net pre-tax unrealized gain position of $1.6 million for which $1.0 million, the tax effected balance, was reclassified from other comprehensive income to beginning retained earnings at adoption.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of cash flows (Topic 230): Classification of certain cash receipts and cash payments." The objective of this guidance is to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. This ASU addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." The objective of issuing this ASU is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. This prohibition on recognition is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. As such, the Board decided that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Consequently, the amendments in this guidance eliminate the exception for an intra-entity transfer of an asset other than inventory. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)." The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this ASU do not provide a definition of restricted cash or restricted cash equivalents. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 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. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's 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. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." This ASU improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and makes certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The Company early adopted ASU 2017-12 during the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.”  This ASU seeks to help entities reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 (Tax Reform Act), enacted on December 22, 2017.  ASU 2018-02 was issued in response to concerns regarding current guidance in GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date, even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income, rather than net income, and as a result the stranded tax effects would not reflect the appropriate tax rate.  ASU 2018-02 allows an entity to make a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects, which is the difference between the historical corporate income tax rate of 35.0% and the newly enacted corporate income tax rate of 21.0%.  The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 31, 2018; however, public business entities are allowed to early adopt ASU 2018-02 in any interim period for which the financial statements have not yet been issued.  ASU 2018-02 may be applied either at the beginning of the period (annual or interim) of adoption or retrospectively to each of the period(s) in which the effect of the change in the U.S. federal corporate tax rate in the Tax Reform Act is recognized.  As a result of the re-measurement of the Company's deferred tax assets following the enactment of the Tax Reform Act, accumulated other comprehensive income included $1.7 million of stranded tax effects at December 31, 2017.  The Company early adopted ASU 2018-02 during the quarter ended March 31, 2018 and made the election to reclassify the stranded tax effects from accumulated other comprehensive income to retained earnings at the beginning of the period of adoption.    

Recently Issued Accounting Pronouncements

In January 2018, the FASB issued ASU No. 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842." This ASU provides an optional transition practical expedient to not evaluate under Topic 842, existing or expired land easements that were not previously accounted for as leases under the current leases guidance in Topic 840. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity adopts Topic 842. An entity that does not elect this practical expedient should evaluate all existing or expired land easements in connection with the adoption of the new lease requirements in Topic 842 to assess whether they meet the definition of a lease. The amendments in this guidance affect the amendments in ASU 2016-02, which are not yet effective but may be early adopted. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements in ASU 2016-02. An entity that early adopted Topic 842 should apply the amendments in this ASU upon issuance. Management does not intend to early adopt this guidance. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In June 2018, the FASB issued ASU 2018-07, "Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting." The amendments of this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842): Targeted Improvements." The amendments of this ASU provide another transition method for the adoption of the new leases standard. Currently, entities are required to adopt the new leases standard using a modified retrospective transition method. The amendments of this ASU provide another transition method by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, this ASU also provides lessors a practical expedient to not separate nonlease components from the associated lease component, similar to the expedient provided for lessees. The amendments related to separating components of a contract affect the amendments in ASU 2016-02, which are not yet effective but can be early adopted. For entities that have not adopted Topic 842 before the issuance of this ASU, the effective date and transition requirements for the amendments in this ASU related to separating components of a contract are the same as the effective date and transition requirements in ASU 2016-02. Management does not intend to early adopt this guidance. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." The amendments of this ASU modify the disclosure requirements about recurring or nonrecurring fair value measurements required under Topic 820, Fair Value Measurement, and require additional disclosures related to unrealized gains and losses included in other comprehensive income. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this ASU. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period, for all entities. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

Business Combinations [Abstract]

Business Acquisitions

BUSINESS ACQUISITIONS

On March 1, 2018, the Company acquired 100% of the outstanding common stock of Floridian Community Holdings, Inc., ("Floridian") the parent company of Floridian Community Bank and Floridian Custody Services, Inc. Under the terms of the acquisition, each share of Floridian common stock was converted into 0.4584 shares of FCB Class A common stock at the effective date. A total of 1,754,362 shares of FCB Class A common stock were issued to holders of Floridian common stock. The Company also paid cash of $7 thousand for fractional shares resulting from the application of the exchange ratio. In addition, the Company incurred a liability of $5.2 million related to Floridian's outstanding stock options that were settled in cash subsequent to the acquisition. The Floridian acquisition will (i) expand the Company's business within demographically attractive markets in southeast Florida; (ii) increase the Company's core deposit base, an important funding source; and (iii) provide the opportunity to sell the Company's broad array of products to Floridians' client base, among other benefits. The results of operations were included in the Company's results beginning on March 1, 2018, the date of acquisition. The fair value of the common shares issued as part of the consideration paid for Floridian was determined using the closing price of the Company's common shares on February 28, 2018. Floridian had total assets of $506.8 million, total liabilities of $465.8 million and operated 5 full-service branches in South Florida as of March 1, 2018. Goodwill of $58.3 million was recognized in the transaction. None of the goodwill recognized is expected to be deductible for income tax purposes.

The Company determined that the acquisition of Floridian constituted a business combination as defined by ASC Topic 805, “Business Combinations”. The acquisition was not considered to be a significant business combination. The assets acquired and liabilities assumed were recorded at their fair values on the date of acquisition. Fair values were determined in accordance with the guidance provided in ASC Topic 820, “Fair Value Measurements”. In many cases, the determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change. The Company utilized the assistance of third-party advisors in the determination of fair value for loans, deposits, other real estate owned and deferred tax assets acquired. The Company may incur losses on the acquired loans that are materially different from losses the Company originally projected.

The Company recorded adjustments to the preliminary fair value estimates in the reporting period in which the adjustments were determined. During the nine months ended September 30, 2018, the Company recorded adjustments to the preliminary fair value estimates resulting in a decrease in assets acquired of $858 thousand, liabilities assumed of $1.1 million, and goodwill of $255 thousand. The adjustments were primarily related to a reduction in the estimated fair value of an assumed liability and other receivables. As of September 30, 2018, the Company has finalized its valuation of the Floridian acquisition.

The following table presents a summary of the assets acquired and liabilities assumed in the Floridian acquisition recorded at fair value:

On July 24, 2018, the Company announced the entry into a definitive merger agreement under which it will be acquired by Columbus, Georgia based Synovus Financial Corp. ("Synovus"). Under the terms of the merger agreement, the Company’s shareholders will receive a fixed ratio of 1.055 shares of Synovus common stock for each common share of the Company in an all-stock transaction. The merger agreement has been unanimously approved by both companies’ Boards of Directors and is subject to customary closing conditions, including approval by the shareholders of both companies and by state and federal bank regulators. The Company and Synovus filed notices and applications to obtain the necessary regulatory approvals on August 22, 2018. The Georgia Department of Banking and Finance approvals were received on September 25, 2018.

On October 9, 2018, an action captioned Stephen Bushansky v. FCB Financial Holdings, Inc. et al., Case 1:18-cv-62399-BB, was filed in the United States District Court, Southern District of Florida on behalf of a purported class of FCB’s stockholders against FCB and its current directors. This complaint alleges violations of Sections 14(a) and 20(a) of the Exchange Act. The action seeks, among other things, to enjoin the defendants from consummating the merger until additional information is disclosed to FCB’s stockholders in advance of the FCB special meeting or to rescind the merger or recover damages to the extent the merger is completed.

On October 11, 2018, an action captioned Paul Parshall v. FCB Financial Holdings, Inc. et al., Case 1:18-cv-01570-LPS, was filed in the United States District Court for the District of Delaware on behalf of a purported class of FCB’s stockholders against FCB, its current directors, Synovus and Merger Sub, alleging violations of Sections 14(a) and 20(a) of the Exchange Act. The action seeks, among other things, to cause defendants to disseminate adequate disclosures, to enjoin defendants from consummating the merger, and to rescind the merger or recover damages to the extent the merger is completed. The court has not acted on either of these complaints, and no relief has been granted as of this time.

At September 30, 2018, the Company’s security portfolio consisted of 355 securities, of which 245 securities were in an unrealized loss position. A total of 137 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 September 30, 2018. 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 were investment grade as of September 30, 2018 and December 31, 2017 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 available for sale debt securities are shown below. The cost of securities sold is based on the specific identification method.

	Three Months Ended September 30,						Nine Months Ended September 30,

Net realized gains (losses)	$	(1,246	)	$	(282	)	$	(1,107	)	$	(794	)

The Company adopted ASU 2016-01 as of January 1, 2018. This guidance requires investments in equity securities with readily determinable fair values to be measured at fair value, with changes in the fair value recognized as a component of noninterest income in the Company's Consolidated Statements of Income. The Company recognized $1.1 million of unrealized gain and $1.1 million of unrealized loss in noninterest income during the three and nine months ended September 30, 2018, respectively, related to equity securities still held at the end of the period.

The Company’s loan portfolio consists of New and Acquired loans. The Company classifies originated loans and purchased loans not acquired through business combinations that did not show evidence of credit deterioration as New loans. The Company classifies loans acquired through business combinations and purchased loans acquired outside of a business combination that show evidence of credit deterioration as Acquired loans. Loans acquired with deteriorated credit quality since origination are accounted for under ASC 310-30, unless specifically excluded from the scope of ASC 310-30. The remaining portfolio of Acquired loans and those loans excluded from the scope of ASC 310-30 are accounted for under ASC 310-20 and are classified as Non-ASC 310-30 loans.

The following tables summarize the Company’s loans by portfolio and segment as of the periods presented, net of deferred fees, costs, premiums and discounts:

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 $3,417 thousand and $(2.7) million between non-accretable and accretable discount during the nine months ended September 30, 2018 and 2017, respectively.

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. During the second quarter 2018, the Company released an unallocated allowance for loan loss of $1.5 million, which was recorded in prior year in response to Hurricane Irma.

The following tables present information related to the ALL for the periods presented:

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 uses interest rate swaps to manage interest rate risk related to borrowings that expose the Company to variability in cash flows due to changes in interest rates. The Company entered into LIBOR-based forward interest rate swaps that are designated as cash flow hedges with the objective of limiting the variability of forecasted interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. Changes in the fair value of interest rate swaps designated as cash flow hedging instruments are reported in accumulated other comprehensive income ("AOCI") and subsequently reclassified into interest expense in the same period in which the related interest on the floating-rate borrowings affects earnings.

The Company is also a party to interest rate derivatives that are not designated as hedging instruments. The Company uses interest rate derivative contracts, such as swaps and caps, in the normal course of business to meet the financial needs of its customers. The interest rate swaps that the Company enters into with customers allow the 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 given default of each counterparty. The Company recorded $4.4 million and $1.5 million of derivative contract fees in noninterest income in the accompanying Consolidated Statement of Income for the three months ended September 30, 2018 and 2017, respectively, and $10.8 million and $4.8 million for the nine months ended September 30, 2018 and 2017, respectively.

In addition, the Company has entered into three risk participation agreements. The notional amount of the risk participation agreements sold was $34.3 million as of September 30, 2018. Assuming all underlying third party customers referenced in the swap agreements defaulted at September 30, 2018, there would be an immaterial amount of exposure to the company. These risk participation agreements mature in 2021.

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 or nine months ended September 30, 2018 or 2017.

The following tables summarize the Company’s derivatives outstanding included in other assets and other liabilities in the accompanying Consolidated Balance Sheets:

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 Tax Disclosure [Abstract]

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 September 30, 2018 and 2017 were 23.5% and 30.2%, respectively. The decrease in the effective tax rate for the third quarter of 2018 was primarily due to the Tax Cuts and Jobs Act of 2017 (the "TCJA") which resulted in a reduction in the maximum federal corporate income tax rate from 35% to 21%, effective January 1, 2018. This was partially offset by a decrease in excess tax benefits recognized at settlement for share-based payments which resulted in recording a $168 thousand tax benefit in the Consolidated Statements of Income for the quarter ended September 30, 2018 compared to $2.1 million for the quarter ended September 30, 2017. 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 nine months ended September 30, 2018 and 2017 were 21.7% and 19.8%, respectively. The increase in the effective tax rate for the nine months ended September 30, 2018 was due to a decrease in excess tax benefits recognized at settlement for share-based payments which resulted in recording a $2.9 million tax benefit in the Consolidated Statements of Income for the nine months ended September 30, 2018 compared to $18.0 million for the nine months ended September 30, 2017. This was partially offset by the TCJA which resulted in a reduction in the maximum federal corporate income tax rate effective January 1, 2018, as well as higher levels of pre-tax income.

2016 Incentive Plan - Restricted Stock Unit Awards

On February 21, 2018, the Compensation Committee granted certain non-employee Directors of the Company a portion of their Directors' compensation for fiscal year 2018 in the form of restricted stock units (the "Directors' RSUs"). 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 19,015 Directors' RSUs were granted with a grant date fair value of $1.1 million. Twenty-five percent (25%) of the RSUs vested on both March 31, 2018, June 30, 2018, and September 30, 2018, and an additional twenty-five percent (25%) will vest on December 31, 2018 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, 2018.

On March 21, 2018, the Compensation Committee granted a target of 84,836 and a maximum of 106,043 restricted stock units (the "Executive RSUs") of Class A Common Stock to certain Executives. The total target grant date fair value of the RSU Award was $4.8 million, up to a maximum of $5.9 million, and will be recognized on a straight-line basis as compensation expense over the requisite vesting period ending December 31, 2020.

On five different dates during the period ended September 30, 2018, the Company granted a total of 53,552 restricted shares to employees (the "Employee RSUs") that vest in-full (i.e. cliff vesting) on the 5-year anniversary of the grant date. The fair value of the Awards on the grant date was $3.0 million and will be recognized as compensation expense over the requisite vesting period ending on the respective 5-year anniversary of the Employee RSU Award's grant date.

The following table presents the activity during the nine months ended September 30, 2018 related to restricted stock units from the 2016 Plan:

Executive Incentive Plan

During the year ended December 31, 2015, the Compensation Committee of the Board of Directors of the Company approved the adoption of the FCB Financial Holdings, Inc. Executive Incentive Plan (the “EIP”). The EIP provides for Annual Incentive Awards and Long-Term Incentive Awards, both of which are subject to achievement of specified performance goals.

Long-Term Incentive Awards

On March 21, 2018, the Compensation Committee granted a Long-Term Award of cash phantom units (“CPUs”) under the Long-Term Incentive component of the EIP which covers a three-year period ending December 31, 2020 (the “Performance Period”). Granted under the award is a target of 18,050 CPUs and a maximum of 22,562 CPUs to a certain Executive. Each CPU is the equivalent in value of a share of Class A Common Stock of the Company, par value $0.001 per share. The total target grant date fair value of the CPU Award was $1.0 million, up to a maximum of $1.3 million, and will be recognized on a straight-line basis as compensation expense over the requisite period ending December 31, 2020.

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 $1.5 million as of September 30, 2018 and $1.1 million as of December 31, 2017.

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:

	September 30, 2018		December 31, 2017
	(Dollars in thousands)
Commitments to fund loans	$	1,159,541	$	926,405
Unused lines of credit	774,695		571,587
Commercial and standby letters of credit	50,945		46,520
Total	$	1,985,181	$	1,544,512

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.

Derivatives—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, interest rate caps, and risk participation agreements where there is no significant deterioration in the counterparties (loan customers) credit risk since origination of the interest rate swap, interest rate cap, or risk participation agreements. The Company values its interest rate swap, interest rate cap, and risk participation agreement positions using market prices provided by a third party which uses primarily observable market inputs. Derivatives are further described in Note 7 “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 or nine months ended September 30, 2018 and 2017, the Company has not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. As of September 30, 2018, there were no interest rate derivatives classified as Level 3.

The following tables present the assets and liabilities measured at fair value on a recurring basis:

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 or nine months ended September 30, 2018.

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 nine months ended September 30, 2018, 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:	September 30, 2018		December 31, 2017		Valuation Technique	Unobservable Inputs	Range (Weighted Average)
(Dollars in thousands)
Impaired loans	$	28,969	$	6,153	Third party appraisals and discounted cash flows	Collateral discounts and discount rates	0% - 100% (7.1%)
Other real estate owned	10,534		14,906		Third party appraisals	Collateral discounts and estimated cost to sell	10	%

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
	(Dollars in thousands)
Negative valuation adjustments:
Impaired loans	$	122	$	—	$	1,715	$	—
Foreclosed real estate	9		54		1,106		437

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 Statements of Income. Impairment charges resulting from the non-recurring changes in fair value of OREO are included in loan and other real estate related expenses in the Consolidated Statements 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:

Certain financial instruments are carried at amounts that approximate fair value due to their short-term nature and generally negligible credit risk. Financial instruments for which fair value approximates the carrying amount at September 30, 2018 and December 31, 2017, 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.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

REVENUE RECOGNITION

On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606)" and all subsequent ASUs that modified Topic 606. As stated in Note 1. "Summary of Significant Accounting Policies", the implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company's historic accounting under Topic 605.

Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with financial guarantees, derivatives, transfers and servicing of loans and lease contracts are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as service charges and deposit related fees, interchange fees, merchant income and sales of other real estate owned. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below.

Service Charges and Fees

Service charges and fees consist of insufficient funds fees, continuous overdraft fees, monthly service charge fees, excessive transaction fees, stop payment fees and other deposit account related fees. Based on the Company's review of the depository contracts and the nature of these fees, the Company grouped the service charges and deposit-related fees embedded in the contracts into two distinct categories, either transactional or non-transactional fees.

Transactional Fees

With respect to transactional fees, the Company recognizes revenue at the time of service. The depository contracts with our customers stipulate that we will continue to provide services until the contract is terminated. Each party can immediately terminate the contract without compensating the other party for the termination (that is, there is no termination penalty). Since the duration of the depository contract doesn’t extend beyond the services already provided because either party can cancel the contract without compensating the other party, the relationship is, in effect, a day-to-day contract. Because the contract doesn’t extend beyond the services performed, the Company recognizes revenue at the time of service as there is no future contract under which to allocate consideration.

Non-Transactional Fees

With respect to monthly non-transactional fees, the Company recognizes revenue each month if it is entitled to the fee because the customer did not meet one of the agreed-upon criteria. Because the contract term does not extend beyond the services already provided (either party can immediately terminate the depository contract without compensating the other party), the Company will not need to make estimates about future monthly fees from a customer. Instead, the Company will recognize revenue for the maintenance fee if the customer does not meet one of the criteria and it would not recognize revenue for the maintenance fee if the customer meets one of the criteria.

Other Noninterest Income

Other noninterest income consists of debit card swipe fees, foreign ATM fees, merchant services revenue, referral income, check printing fees, early withdraw fees, collection fees, wire transfer fees, gain (loss) on sale of other real estate owned, and other miscellaneous fees.

Debit card swipe fees are triggered by cardholder usage and are earned when the customer chooses “debit or credit” at the point of sale. The Bank receives a fee from the network (Interlink, STAR, and PLUS). The VISA international fee is earned when a customer uses a debit card overseas. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Referral fees are earned by either (i) matching a bank customer with a vendor’s credit card where the bank is paid a fee for each approved credit card application, or (ii) refer a customer to a third party for investment services. Check printing fees and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, when the services are rendered or upon completion.

The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if the Company financing is not at a market rate.

The following table presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the periods presented:

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of September 30, 2018 and December 31, 2017, the Company did not have any significant contract balances.

Contract Acquisition Costs

In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2018

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, 2017. 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 two wholly-owned subsidiaries: (i) Florida Community Bank, N.A., a national bank (“Florida Community Bank” or the “Bank”); and (ii) Floridian Custody Services, Inc. ("Custody Services"). Florida Community Bank, headquartered in Weston, Florida, offers a comprehensive range of traditional banking products and services to individual and corporate customers through 51 banking centers located in Florida as of September 30, 2018. Custody Services, headquartered in Davie, Florida, provides clearing and custodian services to deposit brokers and their clients.

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, Custody Services and Florida Community 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 consolidated 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 May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, which superseded 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. This guidance should be applied to all contracts with customers except those that are within the scope of other standards. This ASU became effective for the quarter ended March 31, 2018. The Company elected to adopt the new guidance under the modified retrospective approach. Since the Company's revenue is comprised primarily of net interest income from financial instruments that are within the scope of other standards, including loans and securities, the new guidance did not have a material impact upon adoption. In addition, the adoption of this guidance did not result in any material changes to the method of revenue recognition on the components of noninterest income. Accordingly, the adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In May 2016, the FASB issued ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The amendments in this ASU affect the guidance in ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU clarify the guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The amendments in this ASU affect the guidance in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” which:

• Requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income.

• Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value.

• Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet.

• Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes.

• Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.

• Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements.

• Clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets.

An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the ASU. This ASU became effective the for the quarter ended March 31, 2018. As of January 1, 2018, the Company had equity securities in a net pre-tax unrealized gain position of $1.6 million for which $1.0 million, the tax effected balance, was reclassified from other comprehensive income to beginning retained earnings at adoption.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of cash flows (Topic 230): Classification of certain cash receipts and cash payments." The objective of this guidance is to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. This ASU addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." The objective of issuing this ASU is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. This prohibition on recognition is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. As such, the Board decided that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Consequently, the amendments in this guidance eliminate the exception for an intra-entity transfer of an asset other than inventory. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)." The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this ASU do not provide a definition of restricted cash or restricted cash equivalents. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 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. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's 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. This ASU became effective for the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." This ASU improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and makes certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The Company early adopted ASU 2017-12 during the quarter ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.”  This ASU seeks to help entities reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 (Tax Reform Act), enacted on December 22, 2017.  ASU 2018-02 was issued in response to concerns regarding current guidance in GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date, even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income, rather than net income, and as a result the stranded tax effects would not reflect the appropriate tax rate.  ASU 2018-02 allows an entity to make a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects, which is the difference between the historical corporate income tax rate of 35.0% and the newly enacted corporate income tax rate of 21.0%.  The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 31, 2018; however, public business entities are allowed to early adopt ASU 2018-02 in any interim period for which the financial statements have not yet been issued.  ASU 2018-02 may be applied either at the beginning of the period (annual or interim) of adoption or retrospectively to each of the period(s) in which the effect of the change in the U.S. federal corporate tax rate in the Tax Reform Act is recognized.  As a result of the re-measurement of the Company's deferred tax assets following the enactment of the Tax Reform Act, accumulated other comprehensive income included $1.7 million of stranded tax effects at December 31, 2017.  The Company early adopted ASU 2018-02 during the quarter ended March 31, 2018 and made the election to reclassify the stranded tax effects from accumulated other comprehensive income to retained earnings at the beginning of the period of adoption.    

Recently Issued Accounting Pronouncements

In January 2018, the FASB issued ASU No. 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842." This ASU provides an optional transition practical expedient to not evaluate under Topic 842, existing or expired land easements that were not previously accounted for as leases under the current leases guidance in Topic 840. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity adopts Topic 842. An entity that does not elect this practical expedient should evaluate all existing or expired land easements in connection with the adoption of the new lease requirements in Topic 842 to assess whether they meet the definition of a lease. The amendments in this guidance affect the amendments in ASU 2016-02, which are not yet effective but may be early adopted. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements in ASU 2016-02. An entity that early adopted Topic 842 should apply the amendments in this ASU upon issuance. Management does not intend to early adopt this guidance. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In June 2018, the FASB issued ASU 2018-07, "Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting." The amendments of this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842): Targeted Improvements." The amendments of this ASU provide another transition method for the adoption of the new leases standard. Currently, entities are required to adopt the new leases standard using a modified retrospective transition method. The amendments of this ASU provide another transition method by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, this ASU also provides lessors a practical expedient to not separate nonlease components from the associated lease component, similar to the expedient provided for lessees. The amendments related to separating components of a contract affect the amendments in ASU 2016-02, which are not yet effective but can be early adopted. For entities that have not adopted Topic 842 before the issuance of this ASU, the effective date and transition requirements for the amendments in this ASU related to separating components of a contract are the same as the effective date and transition requirements in ASU 2016-02. Management does not intend to early adopt this guidance. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." The amendments of this ASU modify the disclosure requirements about recurring or nonrecurring fair value measurements required under Topic 820, Fair Value Measurement, and require additional disclosures related to unrealized gains and losses included in other comprehensive income. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this ASU. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period, for all entities. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.
