Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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, 2015. 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 FCB Financial Holdings, Inc. (the “Company”) is a national bank holding company with one wholly-owned national bank subsidiary, Florida Community Bank, N.A. (“Florida Community Bank” or the “Bank”), headquartered in Weston, Florida, offering a comprehensive range of traditional banking products and services to individual and corporate customers through 47 banking centers located in Florida at March 31, 2016. Principles of Consolidation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank’s subsidiaries, which consist of a group of real estate holding companies. Intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The Company’s financial reporting and accounting policies conform to U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates subject to significant change include the allowance for loan losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, contingent consideration liabilities, acquisition-related fair value computations, stock-based compensation and deferred taxes. Recently Adopted Accounting Pronouncements In June 2014, the FASB issued ASU No. 2014-12, “Compensation- Stock Compensation (Topic 718) —Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period”. This update provides specific guidance on whether to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting or as a non-vesting condition that affects the grant-date fair value of an award. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In November 2014, the FASB issued ASU No. 2014-16, “Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or Equity – a consensus of the FASB Emerging Issues Task Force (ASC 815, Derivatives and Hedging)”. This update requires an entity to determine the nature of an instrument by evaluating all economic characteristics and risks of the entire hybrid instrument when determining whether the host is more akin to debit or equity. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, “Amendments to the Consolidated Analysis (ASC 810, Consolidation)” which amends the consolidation requirements of ASC 810 by reducing the number of consolidation models. The guidance places more emphasis on risk of loss when determining a controlling financial interest; reduces the frequency of the application of related-party guidance when determining a controlling financial interest and changes the consolidation requirements of limited partnerships. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, “Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (ASC 225-20, Extraordinary and Unusual Items)” which eliminates the concept of extraordinary items. Under the ASU, extraordinary items will no longer be segregated from the results of ordinary operations and presented separately on the consolidated financial statements. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” which requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in this ASU require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements 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. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. • 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. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application by public business entities to financial statements of fiscal years or interim periods that have not yet been issued or, by all other entities, that have not yet been made available for issuance of the following amendments in this Update are permitted as of the beginning of the fiscal year of adoption: 1. An entity should 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 if the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 2. Entities that are not public business entities are not required to apply the fair value of financial instruments disclosure guidance in the General Subsection of Section 825-10-50. Except for the early application guidance discussed above, early adoption of the amendments in this Update is not permitted. 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 Update. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” which created Topic 842, Leases, and supersedes the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The core principal of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities. For public entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this Update is permitted. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows. In March 2016, the FASB issued ASU No. 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments” which clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-stop decision sequence. The amendments are an improvement to GAAP because they eliminate diversity in practice in assessing embedded contingent call (put) options in debt instruments. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. An entity should apply the amendments in this Update on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year for which the amendments are effective. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting” which eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Update eliminates equity treatment for tax benefits or deficiencies that result from differences between the compensation cost recognized for GAAP purposes and the related tax deduction at settlement or expiration with such changes recognized in income tax expense and excludes excess tax benefits and tax deficiencies from the calculation of assumed proceeds for earnings per share purposes since such amounts are recognized in the income statement, which will result in greater volatility in earnings per share. In addition, this Update simplifies the statements of cash flows by eliminating the bifurcation of excess tax benefits from operating activities to financing activities. Upon adoption, the amendments in this Update provide for a tiered transition approach whereby amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements and forfeitures should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. This Update is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods with early adoption permitted. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.

A total of 131 were in an unrealized loss position for less than 12 months. The unrealized losses for these securities resulted primarily from changes in interest rates. The Company monitors its investment securities for OTTI. Impairment is evaluated on an individual security basis considering numerous factors, and its relative significance varying by situation. The Company has evaluated the nature of unrealized losses in the investment securities portfolio to determine if OTTI exists. The unrealized losses relate to changes in market interest rates and specific market conditions that do not represent credit-related impairments. Furthermore, the Company does not intend to sell nor is it more likely than not that it will be required to sell these investments before the recovery of their amortized cost basis. Management has completed an assessment of each security in an unrealized loss position for credit impairment, including securities with existing characteristics that are covered under the Volcker Rule, and has determined that no individual security was other-than-temporarily impaired at March 31, 2016. The following describes the basis under which the Company has evaluated OTTI: U.S. Government Agencies and Sponsored Enterprises Obligations and Agency Mortgage-Backed Securities (“MBS”): The unrealized losses associated with U.S. Government agencies and sponsored enterprises obligations and agency MBS are primarily driven by changes in interest rates. These securities have either an explicit or implicit U.S. government guarantee. Asset-Backed Securities and Corporate Bonds & Other Debt Securities: Securities were generally underwritten in accordance with the Company’s investment standards prior to the decision to purchase, without relying on a bond issuer’s guarantee in making the investment decision. These investments are investment grade and will continue to be monitored as part of the Company’s ongoing impairment analysis, but are expected to perform in accordance with their terms. Preferred Stock and Other Equity Securities: The unrealized losses associated with preferred stock and other equity securities in large U.S. financial institutions are primarily driven by changes in interest rates. These securities were generally underwritten in accordance with the Company’s investment standards prior to the decision to purchase. Gross realized gains and losses on the sale of securities available for sale are shown below. The cost of securities sold is based on the specific identification method.

Loans, Net	NOTE 3. LOANS, NET The Company’s loan portfolio consists of New and Acquired loans. The Company classifies originated loans and purchased loans not acquired through business combinations as New loans. The Company classifies loans acquired through business combinations as Acquired loans. A portion of the acquired loan portfolio exhibited evidence of deterioration in credit quality since origination, and are accounted for under ASC 310-30. The remaining portfolio of acquired loans consists of loans that were not considered ASC 310-30 loans at acquisition and are classified as Non-ASC 310-30 loans. 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: March 31, 2016 ASC 310-30 Loans Non-ASC 310-30 Loans New Loans (1) Total Real estate loans: Commercial real estate $ 212,041 $ 55,731 $ 1,067,594 $ 1,335,366 Owner-occupied commercial real estate — 20,814 558,659 579,473 1-4 single family residential 40,061 80,199 1,833,190 1,953,450 Construction, land and development 27,973 6,338 543,540 577,851 Home equity loans and lines of credit — 47,362 34,973 82,335 Total real estate loans $ 280,075 $ 210,444 $ 4,037,956 $ 4,528,475 Other loans: Commercial and industrial $ 33,413 $ 8,478 $ 1,064,873 $ 1,106,764 Consumer 2,287 432 5,709 8,428 Total other loans 35,700 8,910 1,070,582 1,115,192 Total loans held in portfolio $ 315,775 $ 219,354 $ 5,108,538 $ 5,643,667 Allowance for loan losses (31,995 ) Loans held in portfolio, net $ 5,611,672 December 31, 2015 ASC Non-ASC New Total Real estate loans: Commercial real estate $ 247,628 $ 55,985 $ 998,141 $ 1,301,754 Owner-occupied commercial real estate — 21,101 524,728 545,829 1-4 single family residential 40,922 84,111 1,541,255 1,666,288 Construction, land and development 28,017 6,338 537,494 571,849 Home equity loans and lines of credit — 49,407 30,945 80,352 Total real estate loans $ 316,567 $ 216,942 $ 3,632,563 $ 4,166,072 Other loans: Commercial and industrial $ 36,783 $ 9,312 $ 972,803 $ 1,018,898 Consumer 2,390 430 5,397 8,217 Total other loans 39,173 9,742 978,200 1,027,115 Total loans held in portfolio $ 355,740 $ 226,684 $ 4,610,763 $ 5,193,187 Allowance for loan losses (29,126 ) Loans held in portfolio, net $ 5,164,061 (1) Balance includes $8.7 million and $7.1 million of deferred fees, costs, and premium and discount as of March 31, 2016 and December 31, 2015, respectively. At March 31, 2016 and December 31, 2015, the unpaid principle balance of ASC 310-30 loans were $387.1 million and $457.9 million, respectively. At March 31, 2016 and December 31, 2015, the Company had pledged loans as collateral for FHLB advances of $2.14 billion and $2.13 billion, respectively. The recorded investments of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process as of March 31, 2016 totaled $4.9 million. The Company held $466.7 million and $464.2 million of syndicated national loans as of March 31, 2016 and December 31, 2015, respectively. During the three months ended March 31, 2016 and 2015, the Company purchased approximately $189.2 million and $89.6 million in loans from third parties. During the three months ended March 31, 2016 and 2015, the Company sold approximately $36.2 million and $7.9 million, respectively in loans to third parties. The accretable discount on ASC 310-30 loans represents the amount by which the undiscounted expected cash flows on such loans exceed their carrying value. The change in expected cash flow for certain ASC 310-30 loan pools resulted in the reclassification of $(9.9) million and $6.7 million between non-accretable and accretable discount during the three months ended March 31, 2016 and 2015, respectively. Changes in accretable discount for ASC 310-30 loans for the three months ended March 31, 2016 and 2015, were as follows: Three Months Ended March 31, 2016 2015 (Dollars in thousands) Balance at January 1, $ 144,152 $ 156,197 Accretion (15,680 ) (12,542 ) Reclassifications from (to) non-accretable difference (9,888 ) 6,650 Balance at March 31, $ 118,584 $ 150,305

Allowance for Loan Losses	NOTE 4. ALLOWANCE FOR LOAN LOSSES The Company’s accounting method for loans and the corresponding allowance for loan losses (“ALL”) differs depending on whether the loans are New or Acquired. The Company assesses and monitors credit risk and portfolio performance using distinct methodologies for Acquired loans, both ASC 310-30 Loans and Non-ASC 310-30 Loans, and New loans. Within each of these portfolios, the Company further disaggregates the portfolios into the following segments: Commercial real estate, Owner-occupied commercial real estate, 1-4 single family residential, Construction, land and development, Home equity loans and lines of credit, Commercial and industrial and Consumer. The ALL reflects management’s estimate of probable credit losses inherent in each of the segments. Changes in the ALL by loan portfolio and segment for the three months ended March 31, 2016 and 2015 are as follows: Commercial Owner- 1-4 Single Construction, Development Home Equity Loans and Lines of Credit Commercial Industrial Consumer Total (Dollars in thousands) Balance at January 1, 2016 $ 8,450 $ 2,243 $ 6,425 $ 3,404 $ 483 $ 7,665 $ 456 $ 29,126 Provision (credit) for ASC 310-30 loans (198 ) — 1 (10 ) — (2 ) (4 ) (213 ) Provision (credit) for non-ASC 310-30 loans (855 ) (58 ) (24 ) — 23 (3 ) 6 (911 ) Provision (credit) for New loans 492 97 907 51 28 984 5 2,564 Total provision (561 ) 39 884 41 51 979 7 1,440 Charge-offs for ASC 310-30 loans — — — (30 ) — (75 ) — (105 ) Charge-offs for non-ASC 310-30 loans — (1 ) — — (35 ) — (6 ) (42 ) Charge-offs for New loans — — — — — — — — Total charge-offs — (1 ) — (30 ) (35 ) (75 ) (6 ) (147 ) Recoveries for ASC 310-30 loans 761 — — — — 11 — 772 Recoveries for non-ASC 310-30 loans 804 — — — — — — 804 Recoveries for New loans — — — — — — — — Total recoveries 1,565 — — — — 11 — 1,576 Ending ALL balance ASC 310-30 loans 2,461 — 27 288 — 387 402 3,565 Non-ASC 310-30 loans 1,033 404 308 36 279 57 4 2,121 New loans 5,960 1,877 6,974 3,091 220 8,136 51 26,309 Balance at March 31, 2016 $ 9,454 $ 2,281 $ 7,309 $ 3,415 $ 499 $ 8,580 $ 457 $ 31,995 Commercial Owner- 1-4 Single Construction, Development Home Commercial Consumer Total (Dollars in thousands) Balance at January 1, 2015 $ 8,206 $ 1,020 $ 4,740 $ 2,456 $ 355 $ 5,745 $ 358 $ 22,880 Provision (credit) for ASC 310-30 loans (81 ) — 64 (20 ) — (24 ) 42 (19 ) Provision (credit) for non-ASC 310-30 loans 32 3 56 (7 ) 4 3 1 92 Provision (credit) for New loans 853 229 383 (181 ) 39 (43 ) (4 ) 1,276 Total provision 804 232 503 (208 ) 43 (64 ) 39 1,349 Charge-offs for ASC 310-30 loans (96 ) — (86 ) (56 ) — (30 ) (60 ) (328 ) Charge-offs for non-ASC 310-30 loans — — (65 ) — — — — (65 ) Charge-offs for New loans — — — — — — — — Total charge-offs (96 ) — (151 ) (56 ) — (30 ) (60 ) (393 ) Recoveries for ASC 310-30 loans 382 — 121 120 — 49 — 672 Recoveries for non-ASC 310-30 loans — — — — — — — — Recoveries for New loans — — — — — 5 — 5 Total recoveries 382 — 121 120 — 54 — 677 Ending ALL balance ASC 310-30 loans 3,460 — 424 702 — 953 272 5,811 Non-ASC 310-30 loans 527 61 405 68 289 52 7 1,409 New loans 5,309 1,191 4,384 1,542 109 4,700 58 17,293 Balance at March 31, 2015 $ 9,296 $ 1,252 $ 5,213 $ 2,312 $ 398 $ 5,705 $ 337 $ 24,513 Credit Quality Indicators In evaluating credit risk, the Company looks at multiple factors; however, management considers delinquency status to be the most meaningful indicator of the credit quality of 1-4 single family residential, home equity loans and lines of credit and consumer loans. Delinquency statistics are updated at least monthly. Internal risk ratings are considered the most meaningful indicator of credit quality for Non-ASC 310-30 and New commercial, construction, land and development and commercial real estate loans. Internal risk ratings are updated on a continuous basis. The following tables present an aging analysis of the recorded investment for delinquent loans by portfolio and segment (excluding loans accounted for under ASC 310-30): Accruing March 31, 2016 30 to 59 60 to 89 90 Days Non- Accrual Total (Dollars in thousands) New loans: Real estate loans: Commercial real estate $ — $ — $ — $ — $ — Owner-occupied commercial real estate — — — — — 1-4 single family residential 14,623 — — 815 15,438 Construction, land and development — — — — — Home equity loans and lines of credit 63 — — — 63 Total real estate loans 14,686 — — 815 15,501 Other loans: Commercial and industrial — — — — — Consumer — — — — — Total other loans — — — — — Total new loans $ 14,686 $ — $ — $ 815 $ 15,501 Acquired loans: Real estate loans: Commercial real estate $ — $ — $ — $ 5,220 $ 5,220 Owner-occupied commercial real estate — — — 2,280 2,280 1-4 single family residential 1,279 — — 3,397 4,676 Construction, land and development — — — — — Home equity loans and lines of credit 689 93 — 2,501 3,283 Total real estate loans 1,968 93 — 13,398 15,459 Other loans: Commercial and industrial 192 — — 877 1,069 Consumer — — — — — Total other loans 192 — — 877 1,069 Total acquired loans $ 2,160 $ 93 $ — $ 14,275 $ 16,528 Accruing December 31, 2015 30 to 59 60 to 89 90 Days Non- Accrual Total (Dollars in thousands) New loans: Real estate loans: Commercial real estate $ — $ — $ — $ — $ — Owner-occupied commercial real estate — 113 — — 113 1-4 single family residential 9,439 869 — 1,454 11,762 Construction, land and development 467 — — — 467 Home equity loans and lines of credit 64 — — — 64 Total real estate loans 9,970 982 — 1,454 12,406 Other loans: Commercial and industrial — — — — — Consumer — — — — — Total other loans — — — — — Total new loans $ 9,970 $ 982 $ — $ 1,454 $ 12,406 Acquired Loans: Real estate loans: Commercial real estate $ 63 $ — $ — $ 5,282 $ 5,345 Owner-occupied commercial real estate — 95 — 2,247 2,342 1-4 single family residential 1,393 697 — 3,016 5,106 Construction, land and development — — — — — Home equity loans and lines of credit 490 97 — 2,295 2,882 Total real estate loans 1,946 889 — 12,840 15,675 Other loans: Commercial and industrial 90 — — 877 967 Consumer — — — 23 23 Total other loans 90 — — 900 990 Total acquired loans $ 2,036 $ 889 $ — $ 13,740 $ 16,665 Loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected may result in deterioration of the repayment capacity of the borrower are categorized as special mention. Loans with well-defined credit weaknesses including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable will be assigned an internal risk rating of doubtful. The following table summarizes the Company’s commercial Non-ASC 310-30 and New loans by key indicators of credit quality.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	NOTE 5. DERIVATIVES The Company is a party to interest rate derivatives that are not designated as hedging instruments. These derivatives are interest rate swaps that the Company enters into with customers to allow customers to convert variable rate loans to fixed rates. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. The changes in the fair value of the swaps offset each other, except for any differences in the credit risk of the counterparties, which is determined by considering the risk rating, probability of default and loss of given default of each counterparty. The Company recorded $1.2 million and $1.7 million of customer swap fees in noninterest income in the accompanying consolidated statement of income for the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016, the Company has not recorded any credit adjustments related to the credit risk of the counterparties. There was no change in the fair value of derivative assets and derivative liabilities attributable to credit risk included in noninterest expense on the statements of income for the three months ended March 31, 2016 or 2015. No derivative positions held by the Company as of March 31, 2016 were designated as hedging instruments under ASC 815-10.

The amount of collateral required to be posted by the Company varies based on the settlement value of outstanding swaps. As of March 31, 2016 and December 31, 2015, 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 12 “Fair Value Measurements,” in the line items “Derivative assets” and “Derivative liabilities.”

Basic and Diluted Earnings Per Share	NOTE 8. 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.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 9. 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 March 31, 2016 and 2015 were 36.1% and 54.6%, respectively. The decrease in the effective tax rate for the first quarter of 2016 was primarily due to the prior year loss associated with the early termination of the FDIC loss share agreements and a deferred tax asset benefit associated with the revaluation of net unrealized built-in losses related to the Company’s acquisition of Great Florida Bank resulting in a prior year tax benefit of $20.3 million as compared to a tax expense of $12.7 million for the three months ended March 31, 2016.

Commitments and Contingencies	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 11. COMMITMENTS AND CONTINGENCIES The Company issues off-balance sheet financial instruments in connection with its lending activities and to meet the financing needs of its customers. These financial instruments include commitments to fund loans and lines of credit as well as commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers. The Company follows the same credit policies in making commitments as it does for instruments recorded on the Company’s consolidated balance sheet. Collateral is obtained based on management’s assessment of the customer’s credit risk. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. As of March 31, 2016 and December 31, 2015, the Company’s reserve for unfunded commitments totaled $1.4 million and $1.5 million, respectively. Fees collected on off-balance sheet financial instruments represent the fair value of those commitments and are deferred and amortized over their term. Financial Instruments Commitments Unfunded commitments are as follows: March 31, 2016 December 31, (Dollars in thousands) Commitments to fund loans $ 660,325 $ 578,730 Unused lines of credit 354,532 358,601 Commercial and standby letters of credit 15,085 14,410 Total $ 1,029,942 $ 951,741 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	3 Months Ended
	Mar. 31, 2016
Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 12. FAIR VALUE MEASUREMENTS When determining the fair value measurements for assets and liabilities and the related fair value hierarchy, the Company considers the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to market observable data for similar assets and liabilities. It is the Company’s policy to maximize the use of observable inputs, minimize the use of unobservable inputs and use unobservable inputs to measure fair value to the extent that observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity, resulting in diminished observability of both actual trades and assumptions that would otherwise be available to value these instruments, or the value of the underlying collateral is not market observable. Although third party price indications may be available for an asset or liability, limited trading activity would make it difficult to support the observability of these quotations. Financial Instruments Carried at Fair Value on a Recurring Basis The following is a description of the valuation methodologies used for financial instruments measured at fair value on a recurring basis, as well as the general classification of each instrument under the valuation hierarchy. Investment Securities—Investment securities available for sale are carried at fair value on a recurring basis. When available, fair value is based on quoted prices for the identical security in an active market and as such, would be classified as Level 1. If quoted market prices are not available, fair values are estimated using quoted prices of securities with similar characteristics, discounted cash flows or matrix pricing models. Investment securities available for sale for which Level 1 valuations are not available are classified as Level 2 if the valuation incorporates primarily observable inputs. Level 2 securities include U.S. Government agencies and sponsored enterprises obligations and agency mortgage-backed securities; state and municipal obligations; asset-backed securities; and corporate debt and other securities. Pricing of these securities is generally spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities. Interest Rate Derivatives—Interest rate derivatives are reported at estimated fair value utilizing Level 2 inputs and are included in other assets and other liabilities and consist of interest rate swaps where there is no significant deterioration in the counterparties (loan customers) credit risk since origination of the interest rate swap. The Company values its interest rate swap positions using market prices provided by a third party which uses primarily observable market inputs. Interest rate derivatives are further described in Note 5 “Derivatives.” For purposes of potential valuation adjustments to our derivative positions, the Company evaluates the credit risk of its counterparties as well as our own credit risk. Accordingly, the Company has considered factors such as the likelihood of default, expected loss given default, net exposures and remaining contractual life, among other things, in determining if any estimated fair value adjustments related to credit risk are required. The Company reviews counterparty exposure quarterly, and when necessary, appropriate adjustments are made to reflect the exposure. For the three months ended March 31, 2016 or 2015, the Company has not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. As of March 31, 2016, there were no interest rate derivatives classified as Level 3. The following table presents the assets and liabilities measured at fair value on a recurring basis: March 31, 2016 Level 1 Level 2 Level 3 Total (Dollars in thousands) Assets: U.S. Government agencies and sponsored enterprises obligations $ — $ 19,168 $ — $ 19,168 U.S. Government agencies and sponsored enterprises mortgage-backed securities — 392,871 — 392,871 State and municipal obligations — 2,445 — 2,445 Asset-backed securities — 484,102 — 484,102 Corporate bonds and other debt securities — 480,816 — 480,816 Preferred stocks and other equity securities 2,092 143,651 — 145,743 Derivative assets - Interest rate contracts — 38,344 — 38,344 Total $ 2,092 $ 1,561,397 $ — $ 1,563,489 Liabilities: Derivative liabilities - Interest rate contracts $ — $ 38,344 $ — $ 38,344 Total $ — $ 38,344 $ — $ 38,344 December 31, 2015 Level 1 Level 2 Level 3 Total (Dollars in thousands) Assets: U.S. Government agencies and sponsored enterprises obligations $ — $ 20,888 $ — $ 20,888 U.S. Government agencies and sponsored enterprises mortgage-backed securities — 393,115 — 393,115 State and municipal obligations — 2,215 — 2,215 Asset-backed securities — 493,934 — 493,934 Corporate bonds and other debt securities — 444,895 — 444,895 Preferred stocks and other equity securities 2,052 167,523 — 169,575 Derivative assets - Interest rate contracts — 21,553 — 21,553 Total $ 2,052 $ 1,544,123 $ — $ 1,546,175 Liabilities: Derivative liabilities - Interest rate contracts $ — $ 21,553 $ — $ 21,553 Total $ — $ 21,553 $ — $ 21,553 There were no transfers of financial assets between levels of the fair value hierarchy during the three months ended March 31, 2016 or 2015. 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 months ended March 31, 2016 and 2015, there was not a change in the methods or significant assumptions used to estimate fair value. Financial Instruments Measured at Fair Value on a Non-Recurring Basis The following table shows significant unobservable inputs used in the non-recurring fair value measurement of level 3 assets and liabilities: Level 3 Asset Fair value Valuation Technique Unobservable Inputs Range (Dollars in thousands) Non-recurring: Loans $ 5,673,393 Third party appraisals and discounted cash flows Collateral discounts and discount rates 0% - 100% Other real estate owned 43,522 Third party appraisals Collateral discounts and estimated cost to sell 10% The following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified. Impaired loans and OREO—The carrying amount of collateral dependent impaired loans is typically based on the fair value of the underlying collateral, which may be real estate or other business assets, less estimated costs to sell. The carrying value of OREO is initially measured based on the fair value, less estimated cost to sell, of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral are typically based on real estate appraisals which utilize market and income valuation techniques incorporating both observable and unobservable inputs. When current appraisals are not available, the Company may use brokers’ price opinions, home price indices, or other available information about changes in real estate market conditions to adjust the latest appraised value available. These adjustments to appraised values may be subjective and involve significant management judgment. The fair value of collateral consisting of other business assets is generally based on appraisals that use market approaches to valuation, incorporating primarily unobservable inputs. Fair value measurements related to collateral dependent impaired loans and OREO are classified within level 3 of the fair value hierarchy. The following tables provide information about certain assets measured at fair value on a non-recurring basis: March 31, 2016 December 31, 2015 (Dollars in thousands) Assets that are still held (classified in Level 3): Impaired loans $ 9,456 $ 9,582 Foreclosed real estate 43,522 39,340 Three Months Ended March 31, 2016 2015 (Dollars in thousands) Negative valuation adjustments: Impaired loans $ — $ — Foreclosed real estate 90 104 Impairment charges resulting from the non-recurring changes in fair value of the underlying collateral of impaired loans are included in the provision for loan losses in the consolidated statement of income. Impairment charges resulting from the non-recurring changes in fair value of OREO are included in other real estate and acquired assets resolution expenses in the consolidated statement of income. The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments are as follows: March 31, 2016 Carrying Fair Level 1 Level 2 Level 3 (Dollars in thousands) Financial Assets: Cash and cash equivalents $ 126,073 $ 126,073 $ 126,073 $ — $ — Available for sale securities 1,525,145 1,525,145 2,092 1,523,053 — FHLB and other bank stock 59,321 59,321 — 59,321 — Loans, net 5,611,672 5,673,393 — — 5,673,393 Loans held for sale 900 900 — 900 — Bank-owned life insurance 169,531 169,531 — 169,531 — Derivative assets - Interest rate contracts 38,344 38,344 — 38,344 — Financial Liabilities: Deposits $ 5,902,379 $ 5,907,850 $ — $ 5,907,850 $ — Advances from the FHLB and other borrowings 950,462 950,775 — 950,775 — Derivative liabilities - Interest rate contracts 38,344 38,344 — 38,344 — December 31, 2015 Carrying Fair Level 1 Level 2 Level 3 (Dollars in thousands) Financial Assets: Cash and cash equivalents $ 102,460 $ 102,460 $ 102,460 $ — $ — Available for sale securities 1,524,622 1,524,622 2,052 1,522,570 — FHLB and other bank stock 59,477 59,477 — 59,477 — Loans, net 5,164,061 5,207,971 — — 5,207,971 Loans held for sale 2,514 2,514 — 2,514 — Bank-owned life insurance 168,246 168,246 — 168,246 — Derivative assets - Interest rate contracts 21,553 21,553 — 21,553 — Financial Liabilities: Deposits $ 5,430,638 $ 5,430,501 $ — $ 5,430,501 $ — Advances from the FHLB and other borrowings 983,183 981,997 — 981,997 — Derivative liabilities - Interest rate contracts 21,553 21,553 — 21,553 — 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 March 31, 2016 and December 31, 2015, include cash and cash equivalents and due from FDIC. The following methods and assumptions were used to estimate the fair value of each class of financial instruments. FHLB and Other Bank Stock: FHLB and other bank stock can be liquidated only by redemption by the issuer, as there is no market for these securities. These securities are carried at par, which has historically represented the redemption price and is therefore considered to approximate fair value. Loans: Fair values for loans are based on a discounted cash flow methodology that considers various factors, including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, whether or not the loan was amortizing and current discount rates. Loans are grouped together according to similar characteristics and are treated in the aggregate when applying various valuation techniques. The discount rates used for loans are based on current market rates for new originations of comparable credit risk and include adjustments for liquidity concerns. The ALL is considered a reasonable estimate of the required adjustment to fair value to reflect the impact of credit risk. This estimate may not represent an exit value as defined in ASC 820. Loans Held for Sale: Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices. 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.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2016
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, 2015. 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 FCB Financial Holdings, Inc. (the “Company”) is a national bank holding company with one wholly-owned national bank subsidiary, Florida Community Bank, N.A. (“Florida Community Bank” or the “Bank”), headquartered in Weston, Florida, offering a comprehensive range of traditional banking products and services to individual and corporate customers through 47 banking centers located in Florida at March 31, 2016.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank’s subsidiaries, which consist of a group of real estate holding companies. Intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The Company’s financial reporting and accounting policies conform to U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates subject to significant change include the allowance for loan losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, the carrying value of OREO, the fair value of financial instruments, the valuation of goodwill and other intangible assets, contingent consideration liabilities, acquisition-related fair value computations, stock-based compensation and deferred taxes.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2014, the FASB issued ASU No. 2014-12, “Compensation- Stock Compensation (Topic 718) —Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period”. This update provides specific guidance on whether to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting or as a non-vesting condition that affects the grant-date fair value of an award. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In November 2014, the FASB issued ASU No. 2014-16, “Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or Equity – a consensus of the FASB Emerging Issues Task Force (ASC 815, Derivatives and Hedging)”. This update requires an entity to determine the nature of an instrument by evaluating all economic characteristics and risks of the entire hybrid instrument when determining whether the host is more akin to debit or equity. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, “Amendments to the Consolidated Analysis (ASC 810, Consolidation)” which amends the consolidation requirements of ASC 810 by reducing the number of consolidation models. The guidance places more emphasis on risk of loss when determining a controlling financial interest; reduces the frequency of the application of related-party guidance when determining a controlling financial interest and changes the consolidation requirements of limited partnerships. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, “Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (ASC 225-20, Extraordinary and Unusual Items)” which eliminates the concept of extraordinary items. Under the ASU, extraordinary items will no longer be segregated from the results of ordinary operations and presented separately on the consolidated financial statements. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” which requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in this ASU require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update became effective for the first quarter ended March 31, 2016. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements 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. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. • 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. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application by public business entities to financial statements of fiscal years or interim periods that have not yet been issued or, by all other entities, that have not yet been made available for issuance of the following amendments in this Update are permitted as of the beginning of the fiscal year of adoption: 1. An entity should 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 if the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 2. Entities that are not public business entities are not required to apply the fair value of financial instruments disclosure guidance in the General Subsection of Section 825-10-50. Except for the early application guidance discussed above, early adoption of the amendments in this Update is not permitted. 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 Update. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” which created Topic 842, Leases, and supersedes the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The core principal of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities. For public entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this Update is permitted. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows. In March 2016, the FASB issued ASU No. 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments” which clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-stop decision sequence. The amendments are an improvement to GAAP because they eliminate diversity in practice in assessing embedded contingent call (put) options in debt instruments. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. An entity should apply the amendments in this Update on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year for which the amendments are effective. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting” which eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Update eliminates equity treatment for tax benefits or deficiencies that result from differences between the compensation cost recognized for GAAP purposes and the related tax deduction at settlement or expiration with such changes recognized in income tax expense and excludes excess tax benefits and tax deficiencies from the calculation of assumed proceeds for earnings per share purposes since such amounts are recognized in the income statement, which will result in greater volatility in earnings per share. In addition, this Update simplifies the statements of cash flows by eliminating the bifurcation of excess tax benefits from operating activities to financing activities. Upon adoption, the amendments in this Update provide for a tiered transition approach whereby amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements and forfeitures should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. This Update is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods with early adoption permitted. The Company is currently evaluating this guidance to determine the impact on its consolidated financial position, results of operations or cash flows.
