Accounting Policies [Abstract]
Basis of Presentation	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 ("U.S. GAAP") 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. GAAP 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, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 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, 2019 . 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. The Company has 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 credit losses, acquisition accounting and purchased loans, intangible assets and impairment testing, other fair value adjustments, income taxes and realization of deferred tax assets and contingent liabilities. Adoption of new accounting pronouncements: On January 1, 2020, the Company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 326 Financial Instruments - Credit Losses ("ASC Topic 326") which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss ("CECL") methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity ("HTM") debt securities. It also applies to off-balance sheet credit exposure such as loan commitments, standby letters of credit, financial guarantees and other similar instruments. In addition, ASC Topic 326 changed the accounting for impairment of available-for-sale ("AFS") debt securities. The Company adopted ASC Topic 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for the reporting period beginning after January 1, 2020 are presented under ASC Topic 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The following table reflects the cumulative effect of adoption: (in thousands) December 31, 2019 CECL adoption impact January 1, 2020 Loans $ 5,198,404 $ (706 ) $ 5,197,698 Allowance for credit losses 35,154 21,226 56,380 Reserve for unfunded commitments 140 1,837 1,977 Deferred tax assets 16,457 (5,481 ) 10,976 Retained earnings 195,813 (16,876 ) 178,937 ASC Topic 326 introduced new definitions and criteria for categorizing purchased loans. Loans that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination are classified as purchased credit deteriorated ("PCD"). Acquired loans which do not meet the definition of PCD are classified by the Company as acquired non-PCD. At the date of adoption, the Company reclassified all loans previously classified as purchased credit impaired ("PCI") to PCD, and increased the allowance by $0.7 million with a corresponding adjustment to these loans' amortized cost basis. The remaining noncredit discount on loans previously classified as PCI was $0.9 million , which will be accreted into interest income over the remaining life of the loans. Under CECL, the Company estimates the allowance using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit losses provide the basis for estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, loan to value ratios, borrower credit characteristics, loan seasoning or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. For loans analyzed on a collective basis, the Company has developed an allowance model based on an analysis of probability of default ("PD") and loss given default ("LGD") to determine an expected loss by loan segment. PDs and LGDs are developed by analyzing the average historical loss migration of loans to default. The Company excludes accrued interest on loans from its determination of allowance. The allowance estimation process also applies an economic forecast scenario over a three year forecast period. The forecast may utilize one scenario or a composite of scenarios based on management's judgment and expectations around the current and future macroeconomic outlook. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modification unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring ("TDR") will be executed with an individual borrower, or the extension or renewal options are explicitly stated in the contract and are not unconditionally under the control of the Company. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life of the loans within each segment. Adjustments may be made to baseline reserves based on an assessment of internal and external influences on credit quality not fully reflected in the quantitative components of the allowance model. These influences may include elements such as changes in concentration, macroeconomic conditions, recent observable asset quality trends, staff turnover, regional market conditions, employment levels and loan growth. Based upon management's assessments of these factors, the Company may apply qualitative adjustments to the allowance. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. Loans evaluated individually are collateral dependent and primarily secured by real estate. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulty, is considered to be a TDR. The allowance for credit losses on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit losses is determining by discounting the expected future cash flows at the original interest rate of the loan. The Company estimates a reserve for unfunded commitments, which is reported separately from the allowance for credit losses within other liabilities. The reserve is based upon the same quantitative and qualitative factors applied to the collectively evaluated loan portfolio. All HTM debt securities are issued by government sponsored entities, which are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. In addition, the credit rating on all the Company's HTM debt securities as of the date of adoption is AA+. There is no history of the government withholding or limiting support to these agencies, nor is there any indication of change to that historical support. While the potential for default on these securities may be something greater than zero, the long history with no credit losses, the implied government guarantee of principal and interest payments and the high credit rating of the HTM portfolio provide sufficient basis for the current expectation that there is zero risk of loss if default were to occur. As a result, the Company recorded no allowance for HTM debt securities with a fair value less than amortized cost basis at the date of adoption. ASC Topic 326 amended the existing other-than-temporary-impairment guidance for AFS securities, requiring credit losses to be recorded as an allowance rather than through a permanent write-down. When evaluating AFS debt securities under ASC Topic 326, the Company has evaluated whether the decline in fair value is attributed to credit losses or other factors using both quantitative and qualitative analyses, including cash flow analysis, review of credit ratings, remaining payment terms, prepayment speeds and analysis of macro-economic conditions. At the date of adoption, collateralized loan obligations had unrealized losses of $1.2 million . The collateral for these securities is first lien senior secured corporate debt, and the Company holds senior tranches rated A or higher. Based on this analysis, the Company believes that the unrealized loss position for AFS debt securities at the time of adoption was the result of both broad investment type spreads and the current rate environment. Each investment is expected to recover its price depreciations over its holding period as it moves to maturity and the Company has the intent and ability to hold these securities to maturity if necessary. As a result of this evaluation, the Company concluded that no allowance was appropriate.

Included in "Securities gains (losses), net" for the three months ended March 31, 2020 are gross gains of $0.1 million and gross losses of $0.2 million , and gross gains of $0.2 million and gross losses of $0.3 million for the three months ended March 31, 2019 . Also included in “Securities gains (losses), net” is an increase of $0.1 million for each of the three months ended March 31, 2020 and 2019 in the value of an investment in shares of a mutual fund that invests primarily in CRA-qualified debt securities. At March 31, 2020 , debt securities with a fair value of $319.2 million were pledged primarily as collateral for public deposits and secured borrowings. The amortized cost and fair value of debt securities held-to-maturity and available-for-sale at March 31, 2020 , by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because prepayments of the underlying collateral for these securities may occur, due to the right to call or repay obligations with or without call or prepayment penalties.

CLOs are special purpose vehicles and those in which the Company has invested acquire nearly all first lien, broadly syndicated corporate loans across a diversified band of industries while providing support to senior tranche investors. As of March 31, 2020 , the Company held 29 total positions of which 23 positions with a fair value of $164.6 million , or 88% , are in AAA/AA tranches, and six positions with a fair value of $21.1 million , or 12% , are in A rated tranches, with average credit support of 31% and 18% , respectively. The Company evaluates the securities for potential credit losses by modeling expected loan level defaults, recoveries, and prepayments for each CLO security. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at March 31, 2020 , no allowance for credit losses has been recorded. At March 31, 2020 , the Company had $2.4 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $37.8 million . The collateral underlying these mortgage investments is primarily residential real estate. The securities have average credit support of 16% and low loan to value ratios. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at March 31, 2020 , no allowance for credit losses has been recorded. All HTM debt securities are issued by government sponsored entities, which are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. In addition, the credit rating on all HTM debt securities is AA+. While the potential for default on these securities may be something greater than zero, the long history with no credit losses, the implied government guarantee of principal and interest payments and the high credit rating of the HTM portfolio provide sufficient basis for the current expectation that there is no risk of loss if default were to occur. Despite the emergence of significant market changes and increasing degrees of uncertainty in the U.S. economy late in the first quarter of 2020, there has to date been no specific impact on the agencies or changes in the nature or quality of the guarantee they provide. As a result, as of March 31, 2020 , no allowance for credit losses has been recorded. Included in other assets at March 31, 2020 is $42.8 million of Federal Home Loan Bank and Federal Reserve Bank stock stated at par value. The Company has not identified events or changes in circumstances which may have a significant adverse effect on the fair value of these cost method investment securities. Also included in other assets is a $6.5 million investment in a CRA-qualified mutual fund carried at fair value. Accrued interest receivable on AFS and HTM debt securities of $3.4 million and $0.6 million at March 31, 2020 , respectively, and $3.8 million and $0.6 million at December 31, 2019 , respectively, is also included in other assets. The Company holds 11,330 shares of Visa Class B stock, which following resolution of Visa litigation will be converted to Visa Class A shares. Under the current conversion ratio that became effective September 27, 2019 , the Company would receive 1.6228 shares of Class A stock for each share of Class B stock for a total of 18,386

Receivables [Abstract]
Loans	Loans Loans held for investment are categorized into the following segments: • Construction and land development: Loans are extended to both commercial and consumer customers which are collateralized by and for the purpose of funding land development and construction projects, including 1-4 family residential construction, multi-family property and non-farm residential property where the primary source of repayment is from proceeds of the sale, refinancing or permanent financing of the property. • Commercial real estate - owner occupied: Loans are extended to commercial customers for the purpose of acquiring real estate to be occupied by the borrower's business. These loans are collateralized by the subject property and the repayment of these loans is largely dependent on the performance of the company occupying the property. • Commercial real estate - non owner occupied: Loans are extended to commercial customers for the purpose of acquiring commercial property where occupancy by the borrower is not their primary intent. These loans are viewed primarily as cash flow loans, collateralized by the subject property, and the repayment of these loans is largely dependent on rental income from the successful operation of the property. • Residential real estate: Loans are extended to consumer customers and collateralized primarily by 1-4 family residential properties and include fixed and variable mortgages, home equity mortgage and home equity lines of credit. Loans are primarily written based on conventional loan agency guidelines, including loans that exceed agency value limitations. Source of repayments may be from the occupant of the residential property or from cash flows on rental income from the successful operation of the property. • Commercial and financial: Loan are extended to commercial customers. The purpose of the loans can range from working capital, physical asset expansion, asset acquisition or other business purposes. Loans may be collateralized by assets owned by the borrower or the borrower's business. Commercial loans are based primarily on the historical and projected cash flow of the borrower's business and secondarily on the capacity of credit enhancements, guarantees and underlying collateral provided by the borrower. • Consumer: Loans are extended to consumer customers. The segment includes both installment loans and lines of credit which may be collateralized or non-collateralized.

The following classifications are used to categorize loans under the internal classification system: • Pass: Loans that are not problem loans or potential problem loans are considered to be pass-rated. • Special Mention: Loans that do not currently expose the Company to sufficient risk to warrant classification in the Substandard or Doubtful categories, but possess weaknesses that deserve management's close attention are deemed to be Special Mention. • Substandard: Loans with the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. • Substandard Impaired: Substandard loans, typically placed on nonaccrual and considered to be collateral dependent. Also includes accruing TDRs. • Doubtful: Loans that have all the weaknesses inherent in those classified Substandard with the added characteristic that the weakness present makes collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The principal balance of loans classified as doubtful are likely to be charged off.

Troubled Debt Restructured Loans The Company’s TDR concessions granted to certain borrowers generally do not include forgiveness of principal balances, but may include interest rate reductions, an extension of the amortization period and/or converting the loan to interest only for a limited period of time. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements. In March 2020, regulatory agencies issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID–19. The agencies confirmed with the staff of the FASB that short–term modifications made on a good faith basis in response to the COVID–19 pandemic to borrowers who were current prior to any relief, are not to be considered TDRs. This includes short–term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant and were made between March 1, 2020 and the earlier of (i) December 31, 2020 or (ii) 60 days after the end of the COVID–19 national emergency. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. In March 2020, the Company processed short-term payment deferrals on loans totaling approximately $512 million to borrowers who were current on payments prior to deferral. None of these payment deferrals have have been classified as TDRs. See additional information in Note M - Subsequent Events.

During the three months ended March 31, 2020 , there were three defaults totaling $1.4 million of loans that had been modified in TDRs within the preceding twelve months. During the three months ended March 31, 2019 , there were no payment defaults on loans that had been modified to a TDR within the preceding twelve months. The Company considers a loan to have defaulted when it becomes 90 days or more delinquent under the modified terms, has been transferred to nonaccrual status, or has been transferred to other real estate owned. For loans measured based on the present value of expected future cash flows, $24,000 and $35,000 , respectively, for the three months ended March 31, 2020 and 2019 , was included in interest income and represents the change in present value attributable to the passage of time.

Forecast data is sourced primarily from Moody’s Analytics, a firm widely recognized for its research, analysis, and economic forecasts. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer term historical loss experience to estimate losses over the remaining life of the loans within each segment. Historical credit losses provide the basis for estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, loan to value ratios, borrower credit characteristics, loan seasoning or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. At March 31, 2020 , the Company utilized Moody’s “U.S. Macroeconomic Outlook Baseline” scenario which predicted a sudden sharp recession in the near term, driven primarily by the COVID-19 pandemic, including a deep drop in U.S. gross domestic product in the second quarter of 2020, followed by a return to growth in the second half of 2020. The Company considered the significant uncertainty of factors assumed in the Baseline scenario, including the timing, number and severity of virus infections, the duration of stay-at-home orders and other limitations on businesses, and the amount and availability of fiscal stimulus, including programs offered under the Coronavirus Aid, Relief, and Economic Security ("CARES") Act. The Company considered the potential that outcomes in any or all of these factors could differ from the Baseline scenario, and qualitative considerations were incorporated reflecting the risk of uncertain, and possibly further deteriorating, economic conditions, and for additional dimensions of risk not captured in the quantitative model. In the Construction & Land Development segment, the increase in loss estimate during the quarter was affected by both the increase in Baseline scenario forecast from the prior period and qualitative adjustments relating to uncertainty of economic conditions. In this segment, the primary source of repayment is typically from proceeds of the sale, refinancing, or permanent financing of the underlying property; therefore, industry and collateral type and estimated collateral values are among the relevant factors in assessing expected losses. In the Commercial Real Estate - Owner Occupied segment, risk characteristics include, but are not limited to, collateral type, loan seasoning, and lien position. The introduction of government sponsored programs, including the CARES Act, and the Company's expectation that borrowers in this segment will benefit from these programs, offset the otherwise detrimental effect of the negative economic outlook. In the Commercial Real Estate - Non Owner Occupied segment, repayment is often dependent upon rental income from the successful operation of the underlying property. Loan performance may be adversely affected by general economic conditions or conditions specific to the real estate market, including property types. Collateral type, loan seasoning, and lien position are among the risk characteristics analyzed for this segment. Modeled results as of March 31, 2020 reflected higher estimated probabilities of default and loss given default, in addition to qualitative adjustments for uncertainty of macroeconomic factors. The Residential Real Estate segment includes first mortgages secured by residential property, and home equity lines of credit. Risk characteristics considered for this segment include, but are not limited to, collateral type, lien position loan to value ratios, and loan seasoning .The impact of the forecast on home equity lines of credit increased the estimated expected losses in this segment, while closed-end single family mortgages were less impacted due to anticipated government stimulus efforts and high borrower FICO scores. In the Commercial & Financial segment, borrowers are primarily small to medium sized professional firms and other businesses, and loans are generally supported by projected cash flows of the business, collateralized by business assets, and/or guaranteed by the business owners. Industry, collateral type, estimated collateral values and loan seasoning are among the relevant factors in assessing expected losses and were affected by a negative economic outlook, in addition to qualitative factors added to consider significant economic uncertainty. Consumer loans include installment and revolving lines, loans for automobiles, boats, and other personal or family purposes. Risk characteristics considered for this segment include, but are not limited to, collateral type, loan to value ratios, loan seasoning and FICO score. Increases in the forecast for expected unemployment rates increased the reserve in this portfolio, as did qualitative considerations of overall uncertainty as to the depth and duration of the economic downturn. The allowance for credit losses is composed of specific allowances for individually evaluated and general allowances grouped into loan pools based on similar characteristics, which are collectively evaluated. The Company’s loan portfolio and related allowance at March 31, 2020 and December 31, 2019 is shown in the following tables: March 31, 2020 Individually Evaluated Collectively Evaluated Total (In thousands) Recorded Investment Associated Allowance Recorded Investment Associated Allowance Recorded Investment Associated Allowance Construction & land development $ 729 $ 13 $ 294,676 $ 4,633 $ 295,405 $ 4,646 Commercial real estate - owner occupied 4,590 252 1,078,303 5,075 1,082,893 5,327 Commercial real estate - non owner occupied 8,916 316 1,372,180 35,327 1,381,096 35,643 Residential real estate 14,661 1,163 1,545,093 18,736 1,559,754 19,899 Commercial and financial 8,618 2,701 787,420 12,769 796,038 15,470 Consumer 754 247 201,268 4,179 202,022 4,426 Totals $ 38,268 $ 4,692 $ 5,278,940 $ 80,719 $ 5,317,208 $ 85,411 December 31, 2019 Individually Evaluated Collectively Evaluated Total (In thousands) Recorded Investment Associated Allowance Recorded Investment Associated Allowance Recorded Investment Associated Allowance Construction & land development $ 5,217 $ 14 $ 319,896 $ 1,828 $ 325,113 $ 1,842 Commercial real estate 20,484 220 2,358,487 13,004 2,378,971 13,224 Residential real estate 16,093 834 1,491,770 6,833 1,507,863 7,667 Commercial and financial 6,631 1,731 771,621 7,985 778,252 9,716 Consumer 337 59 207,868 2,646 208,205 2,705 Totals $ 48,762 $ 2,858 $ 5,149,642 $ 32,296 $ 5,198,404 $ 35,154

Nonrecurring fair value adjustments to loans identified as impaired reflect full or partial write-downs that are based on the loan’s observable market price or current appraised value of the collateral in accordance with ASC Topic 310. 4 Fair value is measured on a nonrecurring basis in accordance with ASC Topic 360. 5 An investment in shares of a mutual fund that invests primarily in CRA-qualified debt securities, reported at fair value in Other Assets. Recurring fair value basis is determined using market quotations. Available for sale debt securities : U.S. Treasury securities are reported at fair value utilizing Level 1 inputs. Other securities are reported at fair value utilizing Level 2 inputs. The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models or discounted cash flow analyses, using observable market data where available. The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. The fair value of collateralized loan obligations is determined from broker quotes. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models. Loans held for sale : Fair values are based upon estimated values to be received from independent third party purchasers. These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans. Interest income is recorded based on the contractual terms of the loan and in accordance with the Company’s policy on loans held for investment. None of the loans were 90 days or more past due or on nonaccrual as of March 31, 2020 and December 31, 2019 . The aggregate fair value and contractual balance of loans held for sale as of March 31, 2020 and December 31, 2019 is as follows: (In thousands) March 31, 2020 December 31, 2019 Aggregate fair value $ 29,281 $ 20,029 Contractual balance 28,591 19,445 Excess 690 584 Loans : Level 2 loans consist of impaired real estate loans which are collateral dependent. Fair value is based on recent real estate appraisals less estimated costs of sale. For residential real estate impaired loans, appraised values or internal evaluations are based on the comparative sales approach. Level 3 loans consist of commercial and commercial real estate impaired loans. For these loans evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost and/or income approach. A significant unobservable input in the income approach is the estimated capitalization rate for a given piece of collateral. At March 31, 2020 , the capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.5% . Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time. As such, the fair value of these impaired loans is considered level 3 in the fair value hierarchy. Impaired loans measured at fair value total $9.1 million with a specific reserve of $4.7 million at March 31, 2020 , compared to $5.1 million with a specific reserve of $2.9 million at December 31, 2019 . For loans classified as level 3, changes included loan additions of $4.3 million offset by paydowns and chargeoffs of $0.5 million for the three months ended March 31, 2020 . Other real estate owned : When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of other real estate owned (“OREO”) is classified as a level 2 input. When the fair value of OREO is based on appraisals which require significant adjustments to market-based valuation inputs or apply an income approach based on unobservable cash flows, the fair value of OREO is classified as level 3. For OREO classified as level 3 during the three months ended March 31, 2020 , changes included additions of foreclosed loans of $4.5 million , offset by sales of $3.3 million . Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarter-end valuation process. There were no such transfers for loans and OREO classified as level 3 during the three months ended March 31, 2020 and 2019 . The carrying amount and fair value of the Company’s other financial instruments that were not disclosed previously in the balance sheet and for which carrying amount is not fair value as of March 31, 2020 and December 31, 2019 is as follows: (In thousands) Carrying Amount Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2020 Financial Assets Debt securities held-to-maturity 1 $ 252,373 $ — $ 261,218 $ — Time deposits with other banks 3,742 — — 3,763 Loans, net 5,222,692 — — 5,277,017 Financial Liabilities Deposit liabilities 5,887,499 — — 5,892,960 Federal Home Loan Bank (FHLB) borrowings 265,000 — — 264,813 Subordinated debt 71,155 — 64,080 — December 31, 2019 Financial Assets Debt securities held-to-maturity 1 $ 261,369 $ — $ 262,213 $ — Time deposits with other banks 3,742 — — 3,744 Loans, net 5,158,127 — — 5,139,491 Financial Liabilities Deposit liabilities 5,584,753 — — 5,584,621 Federal Home Loan Bank (FHLB) borrowings 315,000 — — 314,995 Subordinated debt 71,085 — 64,017 — 1 See Note D for further detail of individual investment categories. The short maturity of Seacoast’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest bearing deposits with other banks, and securities sold under agreements to repurchase, maturing within 30 days. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at March 31, 2020 and December 31, 2019 : Held to maturity debt securities : These debt securities are reported at fair value utilizing level 2 inputs. The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models or discounted cash flow analyses, using observable market data where available. The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models. Loans : Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial or mortgage. Each loan category is further segmented into fixed and adjustable-rate interest terms as well as performing and nonperforming categories. The fair value of loans is calculated by discounting scheduled cash flows through the estimated life including prepayment considerations, using estimated market discount rates that reflect the risks inherent in the loan. The fair value approach considers market-driven variables including credit related factors and reflects an “exit price” as defined in ASC Topic 820. Deposit liabilities : The fair value of demand deposits, savings accounts and money market deposits is the amount payable at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for funding of similar remaining maturities.

Business Combinations	Business Combinations Acquisition of First Bank of the Palm Beaches On March 13, 2020 , the Company completed its acquisition of First Bank of the Palm Beaches (“FBPB”). FBPB was merged with and into Seacoast Bank. FBPB operated two branches in the Palm Beach market. As a result of this acquisition, the Company expects to enhance its presence in the Palm Beach market, expand its customer base and leverage operating cost through economies of scale, and positively affect the Company’s operating results. The Company acquired 100% of the outstanding common stock of FBPB. Under the terms of the definitive agreement, each share of FBPB common stock was converted into the right to receive 0.2000 shares of Seacoast common stock.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events During the first quarter of 2020, the global economy began experiencing a downturn related to the impacts of the COVID-19 global pandemic. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law. The CARES Act includes provisions for the Paycheck Protection Program (“PPP”) offered through the U.S. Small Business Administration (“SBA”). Loans originated under this program include principal and interest which may be forgiven provided the borrower uses the funds in a manner consistent with PPP guidelines. These loans have a contractual maturity of two years , a contractual rate of interest of 1% , and have an automatic six month payment deferral. In the month of April, 2020, Seacoast processed over 3,700 loans for its customers totaling over $530 million with an average loan size of $143,000 . The SBA has outlined a fee structure based on loan size, whereby institutions will be paid 5% for loans of not more than $350,000, 3% for loans of more than $350,000 and less than $2 million, and 1% for loans of at least $2 million. These fees, net of the loan-specific costs, will be deferred and recognized as an adjustment to yield over the expected life of the loans. There is significant uncertainty about how borrowers will seek and qualify for forgiveness. As a result, the expected life of these loans and the impact on loan yields to future periods cannot currently be determined with certainty, and estimates will be periodically updated as more information becomes available. Seacoast has also provided borrowers affected by the pandemic with short-term loan payment deferrals. In March 2020, regulatory agencies issued an interagency statement on loan modifications, confirming that short-term modifications made on a good faith basis in response to the COVID-19 pandemic to borrowers who were current prior to any relief, are not to be considered troubled debt restructurings. Through April 30, 2020, Seacoast has processed approximately 2,500 loan deferrals totaling $1.0 billion . None of these payment deferrals have been classified as TDRs.

Use of Estimates	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. The Company has 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 credit losses, acquisition accounting and purchased loans, intangible assets and impairment testing, other fair value adjustments, income taxes and realization of deferred tax assets and contingent liabilities.
Adoption of New Accounting Pronouncements and Recently Issued Accounting Standards, Not Yet Adopted	Adoption of new accounting pronouncements: On January 1, 2020, the Company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 326 Financial Instruments - Credit Losses ("ASC Topic 326") which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss ("CECL") methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity ("HTM") debt securities. It also applies to off-balance sheet credit exposure such as loan commitments, standby letters of credit, financial guarantees and other similar instruments. In addition, ASC Topic 326 changed the accounting for impairment of available-for-sale ("AFS") debt securities. The Company adopted ASC Topic 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for the reporting period beginning after January 1, 2020 are presented under ASC Topic 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The following table reflects the cumulative effect of adoption: (in thousands) December 31, 2019 CECL adoption impact January 1, 2020 Loans $ 5,198,404 $ (706 ) $ 5,197,698 Allowance for credit losses 35,154 21,226 56,380 Reserve for unfunded commitments 140 1,837 1,977 Deferred tax assets 16,457 (5,481 ) 10,976 Retained earnings 195,813 (16,876 ) 178,937 ASC Topic 326 introduced new definitions and criteria for categorizing purchased loans. Loans that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination are classified as purchased credit deteriorated ("PCD"). Acquired loans which do not meet the definition of PCD are classified by the Company as acquired non-PCD. At the date of adoption, the Company reclassified all loans previously classified as purchased credit impaired ("PCI") to PCD, and increased the allowance by $0.7 million with a corresponding adjustment to these loans' amortized cost basis. The remaining noncredit discount on loans previously classified as PCI was $0.9 million , which will be accreted into interest income over the remaining life of the loans. Under CECL, the Company estimates the allowance using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit losses provide the basis for estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, loan to value ratios, borrower credit characteristics, loan seasoning or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. For loans analyzed on a collective basis, the Company has developed an allowance model based on an analysis of probability of default ("PD") and loss given default ("LGD") to determine an expected loss by loan segment. PDs and LGDs are developed by analyzing the average historical loss migration of loans to default. The Company excludes accrued interest on loans from its determination of allowance. The allowance estimation process also applies an economic forecast scenario over a three year forecast period. The forecast may utilize one scenario or a composite of scenarios based on management's judgment and expectations around the current and future macroeconomic outlook. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modification unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring ("TDR") will be executed with an individual borrower, or the extension or renewal options are explicitly stated in the contract and are not unconditionally under the control of the Company. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life of the loans within each segment. Adjustments may be made to baseline reserves based on an assessment of internal and external influences on credit quality not fully reflected in the quantitative components of the allowance model. These influences may include elements such as changes in concentration, macroeconomic conditions, recent observable asset quality trends, staff turnover, regional market conditions, employment levels and loan growth. Based upon management's assessments of these factors, the Company may apply qualitative adjustments to the allowance. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. Loans evaluated individually are collateral dependent and primarily secured by real estate. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulty, is considered to be a TDR. The allowance for credit losses on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit losses is determining by discounting the expected future cash flows at the original interest rate of the loan. The Company estimates a reserve for unfunded commitments, which is reported separately from the allowance for credit losses within other liabilities. The reserve is based upon the same quantitative and qualitative factors applied to the collectively evaluated loan portfolio. All HTM debt securities are issued by government sponsored entities, which are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. In addition, the credit rating on all the Company's HTM debt securities as of the date of adoption is AA+. There is no history of the government withholding or limiting support to these agencies, nor is there any indication of change to that historical support. While the potential for default on these securities may be something greater than zero, the long history with no credit losses, the implied government guarantee of principal and interest payments and the high credit rating of the HTM portfolio provide sufficient basis for the current expectation that there is zero risk of loss if default were to occur. As a result, the Company recorded no allowance for HTM debt securities with a fair value less than amortized cost basis at the date of adoption. ASC Topic 326 amended the existing other-than-temporary-impairment guidance for AFS securities, requiring credit losses to be recorded as an allowance rather than through a permanent write-down. When evaluating AFS debt securities under ASC Topic 326, the Company has evaluated whether the decline in fair value is attributed to credit losses or other factors using both quantitative and qualitative analyses, including cash flow analysis, review of credit ratings, remaining payment terms, prepayment speeds and analysis of macro-economic conditions. At the date of adoption, collateralized loan obligations had unrealized losses of $1.2 million . The collateral for these securities is first lien senior secured corporate debt, and the Company holds senior tranches rated A or higher. Based on this analysis, the Company believes that the unrealized loss position for AFS debt securities at the time of adoption was the result of both broad investment type spreads and the current rate environment. Each investment is expected to recover its price depreciations over its holding period as it moves to maturity and the Company has the intent and ability to hold these securities to maturity if necessary. As a result of this evaluation, the Company concluded that no allowance was appropriate. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848). The guidance provides accounting relief for contract modifications that replace an interest rate impacted by reference rate reform (e.g., London Inter-bank Offered Rate ("LIBOR")) with a new alternative reference rate. The guidance is applicable to investment securities, receivables, loans, debt, leases, derivatives and hedge accounting elections and other contractual arrangements. The Company applied the guidance prospectively beginning April 1, 2020, and expects no material impact on its financial position, results of operations or cash flows.
