Basis of Presentation

Basis of Presentation: The accompanying unaudited condensed consolidated financial statements of Seacoast Banking Corporation of Florida and its subsidiaries (the "Company") have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Adoption of new accounting pronouncements: On January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, “Leases”, and all the related amendments (collectively, Accounting Standards Codification “ASC” Topic 842) through a cumulative-effect adjustment.

The new guidance requires a lessee to recognize at the transition date right-of-use assets ("ROUA") and lease liabilities for all operating leases. Upon adoption, the Company recognized ROUAs of $29 million and lease liabilities of $33 million. Operating lease liabilities are measured based on the present value of lease payments over the lease term. At the transition date, ROUA was determined by adjusting lease liabilities for the carrying balances of deferred rent under ASC Topic 840 Leases, cease-use liabilities under ASC Topic 420 Exit or Disposal Cost Obligations, and assets and liabilities recognized under ASC Topic 805 Business Combinations for acquired operating leases, which aggregated to $4 million.

We determine if an arrangement is a lease at the inception of a lease. ROUAs represent our right to use the underlying asset and lease liabilities represent our obligation to make lease payments for the lease term. Operating lease ROUAs and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the appropriate term and information available at commencement date in determining the present value of lease payments. The lease term may include options to extend the lease when it is reasonably certain that we will exercise that option. ROUAs and operating lease liabilities are reported in Other Assets and Other Liabilities, respectively, in the Consolidated Balance Sheet. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company elected certain practical expedients offered by the FASB for all classes of leased assets. As a result, the Company has not reassessed whether existing contracts are or contain leases, nor has the Company reassessed the classification of existing leases. The Company elected not to separate lease and non-lease components and instead accounts for them as a single lease component. The Company also elected to exclude short-term leases from the recognition of right-of-use assets and lease liabilities. Therefore, if the lease term is equal to or less than twelve months (including the renewal options that we are reasonably certain to exercise) and we are not reasonably certain to exercise any available purchase options in the lease, we do not apply the new lease accounting guidance for those leases. The Company did not elect the hindsight practical expedient, which allows entities to use hindsight when determining lease term and impairment of right-of-use assets.

On January 1, 2019, we adopted ASU 2017-12 “Derivatives and Hedging" (Topic 815): Targeted Improvements to Accounting for Hedging Activities. Upon adoption, we reclassified certain debt securities from held to maturity to available for sale. The following table summarizes the impact:



	January 1, 2019
(In thousands)	Amortized Cost		Net Unrealized Gain (Loss) Reflected in OCI			Fair Value
Private mortgage-backed securities and collateralized mortgage obligations	$	21,526	$	147		$	21,673
Collateralized loan obligations	32,000		(877		)	31,123
Totals	$	53,526	$	(730	)	$	52,796

Use of Estimates: The preparation of these condensed consolidated financial statements requires management to make judgments in the application of certain of its accounting policies that involve significant estimates and assumptions. We have established policies and control procedures that are intended to ensure valuation methods are well controlled and applied consistently from period to period. These estimates and assumptions, which may materially affect the reported amounts of certain assets, liabilities, revenues and expenses, are based on information available as of the date of the financial statements, and changes in this information over time and the use of revised estimates and assumptions could materially affect amounts reported in subsequent financial statements. Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, acquisition accounting and purchased loans, intangible assets and impairment testing, other fair value adjustments, other than temporary impairment of securities, income taxes and realization of deferred tax assets and contingent liabilities.
