Accounting Policies [Abstract]  
Significant Accounting Policies Significant Accounting Policies
General: Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) is a single segment financial holding company with one operating subsidiary bank, Seacoast National Bank (“Seacoast Bank”). The Company provides integrated financial services including commercial and retail banking, wealth management, and mortgage services to customers through advanced banking solutions and a network of traditional branch offices and commercial banking centers operated by Seacoast Bank. Seacoast operates primarily in Florida, with concentrations in the state's fastest growing markets, each with unique characteristics and opportunities. Offices stretch from the southeast, including Fort Lauderdale, Boca Raton and Palm Beach, north along the east coast to the Daytona area, into Orlando and Central Florida and the adjacent Tampa market, and west to Okeechobee and surrounding counties.
The consolidated financial statements include the accounts of Seacoast and all its majority-owned subsidiaries but exclude trusts created for the issuance of trust preferred securities. In consolidation, all significant intercompany accounts and transactions are eliminated.
The accounting and reporting policies of the Company are in accordance with accounting principles generally accepted in the United States of America, and they conform to general practices within the applicable industries. Certain prior period amounts have been reclassified to conform to the current period presentation. 
Use of Estimates: The preparation of consolidated financial statements requires management to make judgments in the application of certain 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 measurements, and contingent liabilities.
Recently Adopted Accounting Pronouncements: On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses, which replaced 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 amounts continue to be reported in accordance with previously applicable GAAP. The following table reflects the cumulative effect of adoption:
(in thousands)December 31, 2019CECL adoption impactJanuary 1, 2020
Loans$5,198,404 $(706)$5,197,698 
Allowance for credit losses35,154 21,226 56,380 
Reserve for unfunded commitments140 1,837 1,977 
Deferred tax assets16,457 (5,481)10,976 
Retained earnings195,813 (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 $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 the 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 the 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 of a loan 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 will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and not unconditionally cancellable by 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 for some of the loan pools 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. 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.
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 a 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 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 depreciation 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 at the date of adoption.

Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks and interest-bearing bank balances. Cash equivalents have original maturities of three months or less, and accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value.
Time Deposits with Other Banks: Time deposits with other banks consist of certificates of deposit with original maturities greater than three months and are carried at cost.
Securities Purchased and Sold Agreements: Securities purchased under resale agreements and securities sold under repurchase agreements are generally accounted for as collateralized financing transactions and are recorded at the amount at which the securities were acquired or sold plus accrued interest. It is the Company’s policy to take possession of securities purchased under resale agreements, which are primarily U.S. government and government agency securities. The fair value of securities purchased and sold is monitored and collateral is obtained from or returned to the counterparty when appropriate. 
Securities: Debt securities are classified at date of purchase as available-for-sale or held-to-maturity. Debt securities that may be sold as part of the Company's asset/liability management or in response to, or in anticipation of, changes in interest rates and resulting prepayment risk, or for other factors are stated at fair value with unrealized gains or losses reflected as a component of shareholders' equity net of tax or included in noninterest income as appropriate. Debt securities that the Company has the ability and intent to hold to maturity are carried at amortized cost. Equity securities are stated at fair value with unrealized gains or losses included in noninterest income as securities gains or losses.
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.
Realized gains and losses are included in noninterest income as investment securities gains (losses). Interest and dividends on securities, including amortization of premiums and accretion of discounts on debt securities, is recognized in interest income on an accrual basis using the interest method. The Company anticipates prepayments of principal in the calculation of the effective yield for collateralized mortgage obligations and mortgage backed securities by obtaining estimates of prepayments from independent third parties. The adjusted cost of each specific security sold is used to compute realized gains or losses on the sale of securities on a trade date basis.
Seacoast Bank is a member of the Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) systems. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. Both cash and stock dividends are reported as income. 
Loans Held for Sale: The Company has elected to account for residential mortgage loans originated as held for sale at fair value. Changes in fair value are measured and recorded in Mortgage Banking Fees in noninterest income each period. The Company designates other loans as held for sale when it has the intent to sell them. Such loans are transferred to held for sale at the lower of cost or estimated fair value less cost to sell. At the time of transfer, write-downs on the loans are recorded as charge-offs, establishing a new cost basis upon transfer.

Loans Held for Investment: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered held for investment. Loans originated by Seacoast and held for investment are recognized at the principal amount outstanding, net of unearned income and amounts charged off. Unearned income includes discounts, premiums and deferred loan origination fees reduced by loan origination costs. Unearned income on loans is amortized to interest income over the life of the related loan using the effective interest rate method. Interest income is recognized on an accrual basis.
As a part of business acquisitions, the Company acquires loans that are recorded at fair value on the acquisition date. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date. Any losses after acquisition are recognized through the allowance for credit losses. 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 that do not meet the definition of PCD are classified by the Company as acquired Non-PCD. An allowance for expected credit losses on PCD loans is recorded at the date of acquisition through an adjustment to the loans' amortized cost basis. In contrast, expected credit losses on loans not considered PCD are recognized through the provision for credit losses in net income at the date of acquisition.
The accrual of interest is generally discontinued on loans, except consumer loans, that become 90 days past due as to principal or interest unless collection of both principal and interest is assured by way of collateralization, guarantees or other security. When interest accruals are discontinued, unpaid interest is reversed against interest income. Consumer loans that become 120 days past due are generally charged off. When borrowers demonstrate over an extended period the ability to repay a loan in accordance with the contractual terms of a loan classified as nonaccrual, the loan is returned to accrual status. Interest income on nonaccrual loans is either recorded using the cash basis method of accounting or recognized after the principal has been reduced to zero, depending on the type of loan. 
In response to the COVID-19 pandemic beginning in early 2020, rules defined in the Coronavirus Aid, Relief and Economic Security (“CARES”) Act and a joint statement issued by federal regulators in consultation with FASB provide financial institutions with the option not to apply troubled debt restructure (“TDR”) accounting to eligible loan modifications provided to borrowers affected by the economic impact of the COVID-19 pandemic. Outside of this guidance, 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 determined by discounting the expected future cash flows at the original interest rate of the loan.
It is the Company's practice to ensure that the charge-off policy meets or exceeds regulatory minimums. Losses on unsecured consumer loans are recognized at 90 days past due, compared to the regulatory loss criteria of 120 days. In compliance with Federal Financial Institution Examination Council guidelines, secured consumer loans, including residential real estate, are typically charged-off or charged down between 120 and 180 days past due, depending on the collateral type. Commercial loans and real estate loans are typically placed on nonaccrual status when principal or interest is past due for 90 days or more, unless the loan is both secured by collateral having realizable value sufficient to discharge the debt in-full and the loan is in process of collection. Secured loans may be charged-down to the estimated value of the collateral with previously accrued unpaid interest reversed against interest income. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects. Initial charge-off amounts are based on valuation estimates derived from appraisals, broker price opinions, or other market information. Generally, new appraisals are not received until the foreclosure process is completed; however, collateral values are evaluated periodically based on market information and incremental charge-offs are recorded if it is determined that collateral values have declined from their initial estimates.
Derivative Instruments and Hedging Activities: The Company enters into derivative contracts, including swaps and floors, to meet the needs of customers who request such services and to manage the Company's exposure to interest rate fluctuations. Derivative contracts are carried at fair value and recorded in the consolidated balance sheet within other assets or other liabilities. The gain or loss resulting from changes in the fair value of interest rate swaps designated and qualifying as cash flow hedging instruments is initially reported as a component of other comprehensive income and subsequently reclassified into earnings through interest income in the same period in which the hedged transaction affects earnings.
The Company discontinues hedge accounting prospectively when it is determined that the derivative contract is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is terminated, management determines that the designation of the derivative as a hedging instrument is no longer appropriate or, for a cash flow hedge, the occurrence of the forecasted transaction is no longer probable. When hedge accounting on a cash flow hedge is discontinued, any subsequent changes in fair value of the derivative are recognized in earnings. The cumulative unrealized gain or loss related to a discontinuing cash flow hedge continues to be reported in AOCI and is subsequently reclassified into earnings in the same period in which the hedged transactions affects earnings, unless it is probable that the forecasted transaction will not occur by the end of the originally specified time period, in which case the cumulative unrealized gain or loss in AOCI is reclassified into earnings immediately.
Cash flows resulting from derivative financial instruments that are accounted for as hedges are classified in the cash flow statement in the same category as the cash flows from the hedged items.
See additional disclosures related to derivative instruments and hedging activities in “Note G – Derivatives”.
Loan Commitments and Letters of Credit: Loan commitments and letters of credit are an off-balance sheet item and represent commitments to make loans or lines of credit available to borrowers. The face amount of these commitments represents an exposure to loss, before considering customer collateral or ability to repay. Such commitments are recognized as loans when funded. The Company estimates a reserve for potential losses on 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.
Fees received for providing loan commitments and letters of credit that may result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to noninterest income as banking fees and commissions on a straight-line basis over the commitment period when funding is not expected. 
Fair Value Measurements: The Company measures or monitors the fair value of many of its assets and liabilities. Certain assets are measured on a recurring basis, including available-for-sale securities and loans held for sale. These assets are carried at fair value on the Company’s balance sheets. Additionally, fair value is measured on a non-recurring basis to evaluate assets or
liabilities for impairment or for disclosure purposes. Examples include collateral-dependent loans, OREO, loan servicing rights, goodwill, and long-lived assets.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value.
The Company applies the following fair value hierarchy:
Level 1 – Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts.
Level 2 – Assets and liabilities valued based on observable market data for similar instruments.
Level 3 – Assets and liabilities for which significant valuation assumptions are not readily observable in the market; instruments valued based on the best available data, some of which is internally-developed, and considers risk premiums that a market participant would require.
When determining the fair value measurements for assets and liabilities required or permitted to be recorded at and/or marked to fair value, the Company considers the principal market in which it would transact and considers 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. Nevertheless, certain assets and liabilities are not actively traded in observable markets and the Company must use alternative valuation techniques to derive a fair value measurement.
Bank Premises and Equipment: Bank premises and equipment are stated at cost, less accumulated depreciation and amortization. Premises and equipment include certain costs associated with the acquisition of leasehold improvements. Depreciation and amortization are recognized principally by the straight-line method, over the estimated useful lives as follows: buildings - 25-40 years, leasehold improvements 5-25 years, furniture and equipment - 3-12 years. Leasehold improvements typically amortize over the shorter of lease terms or estimated useful life. Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are written down to fair value with a corresponding impact to noninterest expense
Other Real Estate Owned: Other real estate owned (“OREO”) consists primarily of real estate acquired in lieu of unpaid loan balances. These assets are carried at an amount equal to the loan balance prior to foreclosure plus costs incurred for improvements to the property, but no more than the estimated fair value of the property less estimated selling costs. Any valuation adjustments required at the date of transfer are charged to the allowance for credit losses. Subsequently, unrealized losses and realized gains and losses are included in other noninterest expense. Operating results from OREO are recorded in other noninterest expense.
OREO may also include bank premises no longer utilized in the course of the Company's business (closed branches) that are initially recorded at the lower of carrying value or fair value, less costs to sell. If fair value of the premises is less than amortized book value, a write down is recorded through noninterest expense. Costs to maintain the facility are expensed.
Intangible assets. The Company’s intangible assets consist of goodwill, core deposit intangibles (CDIs) and mortgage servicing rights. Goodwill results from business combinations and represents the difference between the purchase price and the fair value of net assets acquired. Goodwill may be adjusted for up to one year from the acquisition date in the event new information is obtained which, if known at the date of acquisitions would have impacted the fair value of the acquired assets and liabilities. Goodwill is considered to have an indefinite useful life and is not amortized, but rather tested for impairment annually in the fourth quarter, or more often if circumstances arise that may indicate risk of impairment. If impaired, goodwill is written down with a corresponding impact to noninterest expense.
The Company recognizes CDIs that result from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over periods ranging from six to eight years on a straight line basis. The Company evaluates CDIs for impairment annually, or more often if circumstances arise that may indicate risk of impairment. If impaired, the CDI is written down with a corresponding impact to noninterest expense.
Bank owned life insurance (BOLI): The Company, through its subsidiary bank, has purchased or acquired through bank acquisitions, life insurance policies on certain key executives. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Leases: Arrangements are analyzed at inception to determine the existence of a lease. Right-of-use assets (ROUAs) represent the right to use the underlying asset and lease liabilities represent the 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 the Company's leases do not provide an implicit rate, the Company uses its 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 the option will be exercised. 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 and is classified as Occupancy or Furniture and Equipment expense based on the subject asset.
Revenue Recognition: Revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the services provided and is recognized when the promised services (performance obligations) are transferred to a customer, requiring the application of the following five-steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation.
Relevant activity includes:
Service Charges on Deposits: Seacoast Bank offers a variety of deposit-related services to its customers through several delivery channels including branch offices, ATMs, telephone, mobile, and internet banking. Transaction-based fees are recognized when services, each of which represents a performance obligation, are satisfied. Service fees may be assessed monthly, quarterly, or annually; however, the account agreements to which these fees relate can be canceled at any time by Seacoast and/or the customer. Therefore, the contract term is considered a single day (a day-to-day contract).
Wealth Management Income: The Company earns trust fees from fiduciary services provided to trust customers, which include custody of assets, recordkeeping, collection and distribution of funds. Fees are earned over time and accrued monthly as the Company provides services, and are generally assessed based on the market value of the trust assets under management at a particular date or over a particular period. The Company also earns commissions and fees from investment brokerage services provided to its customers through an arrangement with a third-party service provider. Commissions received from the third-party service provider are recorded monthly and are based upon customer activity. Fees are earned over time and accrued monthly as services are provided. The Company acts as an agent in this arrangement and therefore presents the brokerage commissions and fees net of related costs.
Interchange Income: Fees earned on card transactions depend upon the volume of activity, as well as the fees permitted by the payment network. Such fees are recognized by the Company upon fulfilling its performance obligation to approve the card transaction.
Treasury Stock: The Company's repurchase of shares of its common stock are recorded at cost as treasury stock and result in a reduction of shareholders' equity. Activity in treasury stock represents shares traded to offset employee payroll taxes on vested shares. Shares held in treasury are used for employee share purchases through the Company's stock purchase plan.
Stock-Based Compensation: The stock option plans are accounted for under ASC Topic 718 - Compensation - Stock Compensation and the fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with market assumptions. This amount is amortized on a straight-line basis over the vesting period, generally 5 years. For restricted stock awards, which generally vest based on continued service with the Company, the deferred compensation is measured as the fair value of the shares on the date of grant, and the deferred compensation is amortized as salaries and employee benefits in accordance with the applicable vesting schedule, generally straight-line over three years. Some shares vest based upon the Company achieving certain performance goals and salary amortization expense is based on an estimate of the most likely results on a straight line basis. The Company accounts for forfeitures as they occur.
Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and their related tax bases and are measured using the enacted tax rates and laws that are in effect. A valuation allowance is recognized for a deferred tax asset if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. The effect on deferred tax assets and liabilities of a change in rates is recognized as income or expense in the period in which the change occurs. 
Earnings per Share: Basic earnings per share are computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share are based on the
weighted-average number of common shares outstanding during each period, plus common share equivalents calculated for stock options and performance restricted stock outstanding using the treasury stock method.

Cash, Dividend and Loan Restrictions Cash, Dividend and Loan Restrictions
In the normal course of business, the Company and Seacoast Bank enter into agreements, or are subject to regulatory agreements that result in cash, debt and dividend restrictions. A summary of the most restrictive items follows:
Seacoast Bank may be required to maintain reserve balances with the Federal Reserve Bank. There was no reserve requirement at December 31, 2020. The reserve requirement at December 31, 2019 was $38.7 million. The average amount of the reserve requirement in 2020 was $4.8 million compared to $7.9 million in 2019.
Under Federal Reserve regulation, Seacoast Bank is limited as to the amount it may loan to its affiliates, including the Company, unless such loans are collateralized by specified obligations. At December 31, 2020, the maximum amount available for transfer from Seacoast Bank to the Company in the form of loans approximated $90.1 million, if the Company has sufficient acceptable collateral. There were no loans made to affiliates during the periods ending December 31, 2020 and 2019.

At December 31, 2020, the Company had unrealized losses of $1.2 million on mortgage-backed securities and collateralized mortgage obligations issued by government-sponsored entities having a fair value of $204.0 million. These securities are either explicitly or implicitly guaranteed by the U.S. Government and have a long history of no credit losses. The implied government guarantee of principal and interest payments and the high credit rating of the portfolio provide sufficient basis for the current expectation that there is no risk of loss if default were to occur. 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 December 31, 2020, no allowance for credit losses has been recorded.
At December 31, 2020, the Company had $0.6 million of unrealized losses in uncapped 3-month LIBOR floating rate collateralized loan obligations (“CLOs”) having a fair value of $177.2 million. CLOs are special purpose vehicles and those in which the Company has acquired nearly all first-lien, broadly syndicated corporate loans across a diversified band of industries while providing support to senior tranche investors. As of December 31, 2020, all positions held by the Company are in AAA and AA tranches, with average credit support of 35% and 25%, 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 movement and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at December 31, 2020, no allowance for credit losses has been recorded.
At December 31, 2020, the Company had $0.2 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $24.0 million. The collateral underlying these mortgage investments is primarily residential real estate. The securities have average credit support of 22%. 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 December 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. 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 that occurred in the U.S. economy in 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 December 31, 2020, no allowance for credit losses has been recorded.
Included in other assets at December 31, 2020 is $33.9 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. Accrued interest receivable on AFS and HTM debt securities of $3.2 million and $0.4 million at December 31, 2020, respectively, and $3.8 million and $0.6 million at December 31, 2019, respectively, is included in other assets. Also included in other assets is a $6.5 million investment in a mutual fund carried at fair value.
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 shares of Visa Class A stock. The ownership of Visa stock is related to prior ownership in Visa's network, while Visa operated as a cooperative. This ownership is recorded on the Company's financial records at zero basis.

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 rate mortgages, home equity mortgages, and home equity lines of credit. Loans are primarily written based on conventional loan agency guidelines, including loans that exceed agency value limitations. Sources of repayment 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: Loans are extended to commercial customers. The purpose of the loans can be 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.
Paycheck Protection Program (“PPP”): Loans originated under a temporary program established by the CARES Act. Under the terms of the program, balances may be forgiven if the borrower uses the funds in a manner consistent with the program guidelines, and repayment is guaranteed by the U.S. government.
With the adoption of ASC Topic 326 -Financial Instruments - Credit Losses on January 1, 2020, the Company re-evaluated the aggregation of loans into segments, and separated Commercial Real Estate - Owner Occupied from Commercial Real Estate - Non Owner Occupied. In prior years, all Commercial Real Estate loans were considered a single segment. The following tables present net loan balances by segment as of:

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest subsequently received on such loans is accounted for under the cost-recovery method, whereby interest income is not recognized until the loan balance is reduced to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, and future payments are reasonably assured. The Company recognized $0.9 million, $1.3 million, and $0.4 million in interest income on nonaccrual loans during the years ended December 31, 2020, 2019, and 2018, respectively.

Loans by Risk Rating
The Company utilizes an internal asset classification system as a means of identifying problem and potential problem loans. 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: Loans typically placed on nonaccrual and considered to be collateral-dependent or 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.

Loans Modified in Connection with COVID-19 Pandemic
The CARES Act, which was signed into law on March 27, 2020 and amended by the Consolidated Appropriations Act on December 27, 2020, encourages financial institutions to practice prudent efforts to work with borrowers financially impacted by the COVID-19 pandemic by providing an option to exclude from TDR consideration certain loan modifications that might otherwise be categorized as TDRs under ASC 310-40. This option is available for modifications that are deemed to be COVID-related, where the borrower was not more than 30 days past due on December 31, 2019, and the modification is executed between March 1, 2020 and the earlier of (i) January 1, 2022 or (ii) 60 days after the end of the COVID-19 national emergency. Federal banking regulators issued similar guidance that also allows lenders to conclude that short-term modifications for borrowers affected by the pandemic should not be considered TDRs if the borrower was current at the time of modification. Seacoast provided financially impacted borrowers with loan accommodations, primarily consisting of payment deferrals of up to six months. At its peak, loans on deferral represented $1.1 billion, or 21% of total non-PPP loans. As the year progressed, the large majority of these borrowers successfully resumed making contractual payments, and the level of loans with accommodations dropped to $74.1 million, or 1% of total non-PPP loans, at December 31, 2020. Types of outstanding

The TDRs described above resulted in a specific allowance for credit losses of $0.2 million as of December 31, 2020, no specific allowance for credit losses as of December 31, 2019, and $0.5 million in specific allowance for credit losses as of December 31, 2018. During the year ended December 31, 2020, there were no defaults on loans that had been modified in TDRs within the preceding twelve months. There were four defaults totaling $3.2 million of loans modified in TDRs within the twelve months preceding December 31, 2019. During the twelve months ended December 31, 2018, there were no defaults on loans modified in TDRs 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, is charged off or has been transferred to other real estate owned. For loans measured based on the present value of expected future cash flows, $0.1 million, $0.1 million, and $0.2 million for the years ended December 31, 2020, 2019, and 2018, respectively, was included in interest income and represents the change in present value attributable to the passage of time.

Management establishes the allowance using relevant available information from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts to project losses over a three-year forecast period. 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 the 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 current and forecasted environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics.
As of December 31, 2020, the Company utilized Moody’s most recent “U.S. Macroeconomic Outlook Baseline” scenario and considered the significant uncertainty associated with the assumptions in the Baseline scenario, including the potential resurgence of virus infections in Florida and other states, and the resulting potential decline in consumer spending and financial implications for businesses. The Company also considered the amount and availability of fiscal stimulus, including programs offered under the CARES Act and other potential future government programs and actions. Outcomes in any or all of these factors could differ from the Baseline scenario, and the Company incorporated qualitative considerations reflecting uncertainty of economic conditions, the possibility that the characteristics of the economic downturn could be sustained over a more extended period, and for additional dimensions of risk not captured in the quantitative model.

After the adoption of ASC Topic 326 on January 1, 2020, changes in the allowance for credit losses during the year were largely the result of deterioration in economic conditions due to the COVID-19 pandemic, including higher unemployment and losses of business revenue, and expectations as to the severity and duration of the economic recession.

In the Construction and Land Development segment, the increase in reserves during the year was affected by both the outlook for commercial real estate valuations, and qualitative adjustments relating to the 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, the increase in reserves reflects both the impact of higher loan balances, higher unemployment levels, and lower forecasted commercial real estate valuations. Risk characteristics include but are not limited to, collateral type, loan seasoning, and lien position.

In the Commercial Real Estate - Non Owner-Occupied segment, the increase in reserves reflects higher unemployment levels and deterioration in corporate profits over the forecast period. 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.

The Residential Real Estate segment includes first mortgages secured by residential property, and home equity lines of credit. The increase in reserves reflects higher unemployment, partially offset by lower loan balances and continued strength in the Florida housing market. Risk characteristics considered for this segment include, but are not limited to, collateral type, lien position, loan to value ratios, and loan seasoning.

In the Commercial and 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. The increase in reserves reflects an increased proportion of working capital lines compared to loans secured by business assets, higher overall balances, and recessionary conditions. Industry, collateral type, estimated collateral values and loan seasoning are among the relevant factors in assessing expected losses.

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. A decrease in the reserve is attributed to lower loan balances, partially offset by higher unemployment and recessionary conditions.

Balances outstanding under the Paycheck Protection Program are guaranteed by the U.S. government and have not been assigned a reserve.
The allowance for credit losses is composed of specific allowances for loans individually evaluated and general allowances for loans grouped into loan pools based on similar characteristics, which are collectively evaluated. The Company’s loan portfolio and related allowance at December 31, 2020 and 2019 is shown in the following tables.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivatives Derivatives
Back-to-Back Swaps
The Company offers interest rate swaps when requested by customers to allow them to hedge the risk of rising interest rates on their variable rate loans. Upon entering into these swaps, the Company enters into offsetting positions with counterparties in order to minimize the interest rate risk. These back-to-back swaps qualify as freestanding financial derivatives with the fair values reported in other assets and other liabilities. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under the arrangements for financial statement presentation purposes. Gains and losses on these back-to-back swaps, which offset, are recorded through noninterest income. No net gains or losses have been recognized to date on these instruments. As of December 31, 2020, the interest rate swaps had an aggregate notional value of $182.4 million, with a fair value of $13.3 million recorded in other assets and other liabilities. The weighted average maturity is 7.5 years.
Interest Rate Floors Designated as Cash Flow Hedges
The Company has entered into interest rate floor contracts to mitigate exposure to the variability of future cash flows due to changes in interest rates on certain segments of its variable-rate loans. During 2020, the Company entered into two interest rate floor contracts, each with a notional amount of $150.0 million, maturing in October 2023 and November 2023. The Company considers these derivatives to be highly effective at achieving offsetting changes in cash flows attributable to changes in interest rates and has designated them as cash flow hedges. Therefore, changes in the fair value of these derivative instruments are recognized in other comprehensive income. Amortization of the premium paid on cash flow hedges is recognized in earnings over the term of the hedge in the same caption as the hedged item. As of December 31, 2020, the interest rate floors have a fair value of $1.0 million and are recorded in other assets in the consolidated balance sheet. Over the next twelve months the
Company expects to reclassify $0.2 million from accumulated other comprehensive income into interest income related to these agreements.

1Acquired junior subordinated debentures were recorded at their acquisition date fair values, which collectively was $5.6 million lower than face value; this amount is being amortized into interest expense over the remaining term to maturity.
Interest on the trust preferred securities is calculated on the basis of 3-month LIBOR plus spread and is re-set quarterly. The trust preferred securities may be redeemed without penalty, upon approval of the Federal Reserve or upon occurrence of certain events affecting their tax or regulatory capital treatment. Distributions on the trust preferred securities are payable quarterly in March, June, September, and December of each year. The proceeds of the offering of trust preferred securities and common equity securities were used by SBCF Capital Trust I and SBCF Statutory Trust II to purchase the $41.2 million junior subordinated deferrable interest notes issued by the Company, and by SBCF Statutory Trust III to purchase the $12.4 million junior subordinated deferrable interest notes issued by the Company, all of which have terms substantially similar to the trust preferred securities.
The Company has the right to defer payments of interest on the notes at any time or from time to time at the Company's election. Interest can be deferred for a period not longer than five years. If the Company elects to defer interest, it may not, with certain exceptions, declare or pay any dividends or distributions on its capital stock or purchase or acquire any of its capital stock. As of December 31, 2020, 2019 and 2018, all interest payments on trust preferred securities were current.
The Company has entered into agreements to guarantee the payments of distributions on the trust preferred securities and payments of redemption of the trust preferred securities. Under these agreements, the Company also agrees, on a subordinated basis, to pay expenses and liabilities of the Trusts other than those arising under the trust preferred securities. The obligations of the Company under the junior subordinated notes, the trust agreement establishing the Trusts, the guarantees and agreements as to expenses and liabilities, in aggregate, constitute a full and conditional guarantee by the Company of the Trusts' obligations under the trust preferred securities.

Share-based Payment Arrangement [Abstract]  
Employee Benefits and Stock Compensation Employee Benefits and Stock Compensation
The Company’s defined contribution plan covers substantially all employees after one year of service and includes a matching benefit for employees who can elect to defer a portion of their compensation. In addition, amounts of compensation contributed by employees are matched on a percentage basis under the plan. The Company's contributions to this plan charged to operations were $2.8 million in 2020, $2.4 million in 2019, and $2.1 million in 2018.
The Company, through its Compensation and Governance Committee of the board of directors (the “Compensation Committee”), offers equity compensation to employees and non-employee directors of Seacoast and Seacoast Bank in the form
of various share-based awards, including stock options, restricted stock awards (“RSAs”), or restricted stock units (“RSUs”). The awards may vest over time, have certain performance based criteria, or both.
Stock options are granted with an exercise price at least equal to the market price of the Company’s stock at the date of grant. The fair value of options granted is estimated on the date of grant using the Black-Scholes option-pricing model. Compensation cost is amortized on a straight-line basis over the vesting period. Vesting is determined by the Compensation Committee at the time of grant, generally over five years. The options have a maximum term of ten years. 
The fair value of RSAs and RSUs are estimated based on the price of the Company’s common stock on the date of grant. Compensation cost is measured straight-line for RSAs and ratably for RSUs over the vesting period of the awards and reversed for awards which are forfeited due to unfulfilled service or performance criteria. To the extent the Company has treasury shares available, stock options exercised or stock grants awarded may be issued from treasury shares. If treasury shares are insufficient, the Company can issue new shares.
Vesting of share-based awards is immediately accelerated on death or disability of the recipient. The Compensation Committee may, at its discretion, accelerate vesting upon retirement (including a voluntary termination of employment at age 55) for those employees with five or more years of service with the Company, or upon the event of a change-in-control.
Awards are currently granted under the Seacoast 2013 Incentive Plan (“2013 Plan”), which shareholders approved on May 23, 2013 and has been twice amended to increase the number of authorized shares for issuance thereunder to 4,250,000. The 2013 Plan expires on May 26, 2025. Approximately 535,000 shares remain available for issuance as of December 31, 2020.

Included in the table above is the effect of temporary differences associated with the Company's investments in debt securities accounted for under ASC Topic 320, for which no deferred tax expense or benefit was recognized. These items are recorded as Accumulated Other Comprehensive Income in the shareholders' equity section of the consolidated balance sheet. In 2020, unrealized gains of $26.3 million resulted in a deferred tax liability of $5.9 million. In 2019, unrealized gains of $5.7 million resulted in a deferred tax liability of $1.2 million.
At December 31, 2020, the Company's net deferred tax assets (“DTAs”) of $23.6 million consisted of approximately $18.0 million of net U.S. federal DTAs and $5.6 million of net state DTAs.
Management assesses the necessity of a valuation allowance recorded against DTAs at each reporting period. The determination of whether a valuation allowance for net DTAs is appropriate is subject to considerable judgment and requires an evaluation of all positive and negative evidence. Based on an assessment of all of the evidence, including favorable trending in asset quality and certainty regarding the amount of future taxable income that the Company forecasts, management concluded that it was more likely than not that its net DTAs will be realized based upon future taxable income. Management's confidence in the realization of projected future taxable income is based upon analysis of the Company's risk profile and its trending financial performance, including credit quality. The Company believes it can reasonably predict future results of operations that result in taxable income at sufficient levels over the future period of time that the Company has available to realize its net DTA.
A valuation allowance could be required in future periods based on the assessment of positive and negative evidence. Management's conclusion at December 31, 2020 that it is more likely than not that the net DTAs of $23.6 million will be realized is based upon estimates of future taxable income that are supported by internal projections which consider historical performance, various internal estimates and assumptions, as well as certain external data, all of which management believes to be reasonable although inherently subject to judgment. If actual results differ significantly from the current estimates of future taxable income, even if caused by adverse macro-economic conditions, a valuation allowance may need to be recorded for some or all of the Company's DTAs. The establishment of a DTA valuation allowance could have a material adverse effect on the Company's financial condition and results of operations.
Management expects to realize the $23.6 million in net DTAs well in advance of the statutory carryforward period. At December 31, 2020, approximately $2.9 million of DTAs relate to federal net operating losses which will expire in annual installments beginning in 2029 through 2032. Additionally, $1.3 million of the DTAs relate to state net operating losses which will expire in annual installments beginning in 2029 through 2034. Remaining DTAs are not related to net operating losses or credits and therefore, have no expiration date.
The Company recognizes interest and penalties, as appropriate, as part of the provisioning for income taxes. No interest or penalties were accrued at December 31, 2020.
In accordance with ASC Topic 718, Compensation – Stock Compensation, the Company recognized $0.1 million, $0.8 million and $1.1 million in 2020, 2019, and 2018, respectively, of discrete tax benefits related to share-based compensation.
In accordance with ASC Topic 323, Investments-Equity Method and Joint Ventures, amortization of the Company's low-income housing credit investments of $0.9 million, $0.9 million and $1.0 million has been reflected as income tax expense for the years ended December 31, 2020, 2019, and 2018, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the year ended December 31, 2020 were $0.8 million, $0.9 million, and $0.2 million, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the year ended December 31, 2019 were $0.8 million, $0.9 million and $0.2 million, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the year ended December 31, 2018 were $0.8 million, $1.0 million and $0.2 million, respectively. The carrying value of the investments in affordable housing credits is $16.4 million and $7.4 million at December 31, 2020 and 2019, respectively, of which $9.9 million and $0.5 million, respectively, is unfunded.
The Company has no unrecognized income tax benefits or provisions due to uncertain income tax positions. No federal or state income tax return examinations are currently in process. The Company does not expect to record or realize any material unrecognized tax benefits during 2021. The following are the major tax jurisdictions in which the Company operates and the earliest tax year, exclusive of the impact of the net operating loss carryforwards, subject to examination:
Jurisdiction Tax Year
United States of America2017
Florida2017
In September 2019, the State of Florida announced a reduction in the corporate income tax rate from 5.5% to 4.458% for the years 2019, 2020 and 2021. This change resulted in additional income tax expense of $1.1 million upon the write down in the third quarter of 2019 of deferred tax assets affected by the change, offset by a $0.4 million benefit upon adjusting the year-to-date provision to the new statutory tax rate.
As a result of the adoption of ASC 326 - Credit Losses on January 1, 2020, the tax impact relating to the incremental allowance for expected credit losses on loans held at amortized cost has been reflected as a credit to retained earnings to reflect the tax impact of increased credit reserves. Accordingly, $5.5 million of such impact has been reflected as an income tax credit and deferred tax asset on the Company's Consolidated Statements of Financial Condition.
On March 27, 2020, the CARES Act was enacted, and Section 2303(b) of this act provided the Company with an opportunity to carry back net operating losses arising from 2018, 2019 and 2020 to the prior five tax years. Such NOLs were previously valued at the current federal corporate income tax rate of 21%. However, the provisions of the CARES Act provide for NOL carryback claims to be calculated based on a rate of 35%, which was the federal corporate tax rate in effect for many of the carryback years. Consequently, for the year ended December 31, 2020, the Company filed amended tax returns and has recorded the resulting benefit reflecting taxes recoverable at the 35% tax rate. This resulted in the recognition of an additional $0.4 million income tax benefit on the Company's Consolidated Statements of Income.

Required Regulatory Capital
The Company is subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by the regulators, which could have a direct material impact on the financial statements. These requirements involve quantitative measures of assets, liabilities and certain off-balance sheet items calculated pursuant to regulatory guidance. The Company's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total, Tier 1 capital and common equity Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets, all as defined in the regulations.
At December 31, 2020 and 2019, the Company and Seacoast Bank, its wholly-owned banking subsidiary, were both considered “well capitalized” based on the applicable U.S. regulatory capital ratio requirements as reflected in the table below:

Contingent Liabilities and Commitments with Off-Balance Sheet Risk Contingent Liabilities and Commitments with Off-Balance Sheet Risk
The Company and its subsidiaries, because of the nature of their business, are at all times subject to numerous legal actions, threatened or filed. Management presently believes that none of the legal proceedings to which it is a party are likely to have a materially adverse effect on the Company’s consolidated financial condition, or operating results or cash flows.
The Company's subsidiary bank is party to financial instruments with off balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and limited partner equity commitments.
The subsidiary bank’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contract or notional amount of those instruments. The subsidiary bank uses the same credit policies in making commitments and standby letters of credit as they do for on balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Commitments include home equity lines, commercial and consumer lines of credit and construction loans. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The subsidiary bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, equipment, and commercial and residential real estate.
Standby letters of credit are conditional commitments issued by the subsidiary bank to guarantee the performance of a customer to a third party. These instruments have fixed termination dates and most end without being drawn; therefore, they do not represent a significant liquidity risk. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The subsidiary bank holds collateral supporting these commitments for which collateral is deemed necessary. Collateral held for secured standby letters of credit at December 31, 2020 and 2019 totaled $12.4 million and $13.2 million, respectively.
Unfunded limited partner equity commitments at December 31, 2020 totaled $21.4 million that the Company has committed to small business investment companies under the SBIC Act to be used to provide capital to small businesses and entities that provide low income housing tax credits.

1See “Note D - Securities” for further detail of fair value of individual investment categories.
2Recurring fair value basis determined using observable market data.
3See “Note E - Loans”. Nonrecurring fair value adjustments to collateral-dependent loans reflect full or partial write-downs that are based on current appraised values of the collateral in accordance with ASC Topic 310.
4Fair value is measured on a nonrecurring basis in accordance with ASC Topic 360.
5An 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: Level 1 securities consist of U.S. Treasury securities. 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.
Derivative financial instruments: The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. Other derivatives consist of interest rate floors designated as cash flow hedges. The fair values of these instruments are based upon the estimated amount the Company would receive or pay to terminate the instruments, taking into account current interest rates and, when appropriate, the current credit worthiness of the
counterparties. Interest rate floors designated as cash flow hedges are classified within Level 2.
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 the fair value is the best indicator of the resolution of these loans. Fair market value changes occur due to changes in interest rates, the borrower’s credit, the secondary loan market and the market for a borrower’s debt. Interest income is recorded based on contractual terms of the loan in accordance with Company policy on loans held for investment. None of the loans are 90 days or more past due or on nonaccrual as of December 31, 2020 and 2019.
The aggregate fair value and contractual balance of loans held for sale as of December 31, 2020 and 2019 is as follows:

Aggregate fair value$68,890 $20,029 
Contractual balance66,415 19,445 
Excess2,475 584 
Loans: Loans carried at fair value consist of collateral-dependent real estate loans. Fair value is based on recent real estate appraisals less estimated costs of sale. 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 December 31, 2020 the range of capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.3%. 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 loans is considered level 3 in the fair value hierarchy. Collateral-dependent loans measured at fair value totaled $8.8 million with a specific reserve of $7.7 million at December 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, the changes included additions of $11.9 million offset by $8.7 million in paydowns and charge-offs during the twelve months ended December 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 level 2. 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.
Loans of $4.5 million migrated to OREO during the twelve months ended December 31, 2020 and were classified as level 3. Other changes in 2020 to OREO loans classified as level 3 include sales of $4.9 million and charge-offs of $1.6 million, offset by additions of $2.6 million during the twelve months ended December 31, 2020.
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 valuation process. There were no such transfers during the twelve months ended December 31, 2020 and 2019.
The carrying amount and fair value of the Company's other significant financial instruments that were not disclosed previously in the balance sheet and for which carrying amount is not fair value as of December 31, 2020 and December 31, 2019 is as follows:

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, FHLB borrowings and securities sold under agreement to repurchase.
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 December 31, 2020 and December 31, 2019:
Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, mortgage, etc. Each loan category is further segmented into fixed and adjustable rate interest terms and by 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.

Acquisition of First Green Bancorp, Inc.
On October 19, 2018, the Company completed its acquisition of First Green Bancorp, Inc (“First Green”). Simultaneously, upon completion of the merger of First Green and the Company, First Green's wholly owned subsidiary bank, First Green Bank, was merged with and into Seacoast Bank. Prior to the acquisition, First Green operated seven branches in the Orlando, Daytona, and Fort Lauderdale markets.
As a result of this acquisition, the Company enhanced its presence in the Orlando, Daytona and Fort Lauderdale, Florida markets, expanded its customer base and leverage operating cost through economies of scale, and positively affected the Company’s operating results to the extent the Company earns more from interest earning assets than it pays in interest on its interest bearing liabilities.

The factors we considered to identify loans as PCI loans were all acquired loans that were nonaccrual, 60 days or more past due, designated as TDR, graded “special mention” or “substandard.” These loans were then evaluated to determine estimated fair values as of the acquisition date. As required by generally accepted accounting principles, the Company accounted for these loans pursuant to ASC Topic 310-30 at the time of acquisition and until the adoption of ASC Topic 326 on January 1, 2020. The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and fair value of the loans as of October 19, 2018 for purchased credit-impaired loans. Contractually required principal and interest payments have been adjusted for estimated prepayments.

Loans without specifically identified credit deficiency factors were referred to as PULs for disclosure purposes. These loans were then evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida.
The Company believes the deposits assumed from the acquisition have an intangible value. In determining the valuation amount, deposits were analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships.

Certain prior period amounts have been reclassified to conform to the current period presentation.
Use of Estimates Use of Estimates: The preparation of consolidated financial statements requires management to make judgments in the application of certain 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 measurements, and contingent liabilities.
Recently Adopted Accounting Standards and Not Yet Adopted
Recently Adopted Accounting Pronouncements: On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses, which replaced 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 amounts continue to be reported in accordance with previously applicable GAAP. The following table reflects the cumulative effect of adoption:
(in thousands)December 31, 2019CECL adoption impactJanuary 1, 2020
Loans$5,198,404 $(706)$5,197,698 
Allowance for credit losses35,154 21,226 56,380 
Reserve for unfunded commitments140 1,837 1,977 
Deferred tax assets16,457 (5,481)10,976 
Retained earnings195,813 (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 $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 the 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 the 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 of a loan 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 will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and not unconditionally cancellable by 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 for some of the loan pools 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. 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.
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 a 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 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 depreciation 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 at the date of adoption.
Recently Issued Accounting Standards, Not Adopted at December 31, 2020 None this period.
Cash and Cash Equivalents Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks and interest-bearing bank balances. Cash equivalents have original maturities of three months or less, and accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value.
Time deposits with other banks Time Deposits with Other Banks: Time deposits with other banks consist of certificates of deposit with original maturities greater than three months and are carried at cost.
Securities Purchased and Sold Agreements Securities Purchased and Sold Agreements: Securities purchased under resale agreements and securities sold under repurchase agreements are generally accounted for as collateralized financing transactions and are recorded at the amount at which the securities were acquired or sold plus accrued interest. It is the Company’s policy to take possession of securities purchased under resale agreements, which are primarily U.S. government and government agency securities. The fair value of securities purchased and sold is monitored and collateral is obtained from or returned to the counterparty when appropriate.
Securities
Securities: Debt securities are classified at date of purchase as available-for-sale or held-to-maturity. Debt securities that may be sold as part of the Company's asset/liability management or in response to, or in anticipation of, changes in interest rates and resulting prepayment risk, or for other factors are stated at fair value with unrealized gains or losses reflected as a component of shareholders' equity net of tax or included in noninterest income as appropriate. Debt securities that the Company has the ability and intent to hold to maturity are carried at amortized cost. Equity securities are stated at fair value with unrealized gains or losses included in noninterest income as securities gains or losses.
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.
Realized gains and losses are included in noninterest income as investment securities gains (losses). Interest and dividends on securities, including amortization of premiums and accretion of discounts on debt securities, is recognized in interest income on an accrual basis using the interest method. The Company anticipates prepayments of principal in the calculation of the effective yield for collateralized mortgage obligations and mortgage backed securities by obtaining estimates of prepayments from independent third parties. The adjusted cost of each specific security sold is used to compute realized gains or losses on the sale of securities on a trade date basis.
Seacoast Bank is a member of the Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) systems. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. Both cash and stock dividends are reported as income.
Loans Held for Sale Loans Held for Sale: The Company has elected to account for residential mortgage loans originated as held for sale at fair value. Changes in fair value are measured and recorded in Mortgage Banking Fees in noninterest income each period. The Company designates other loans as held for sale when it has the intent to sell them. Such loans are transferred to held for sale at the lower of cost or estimated fair value less cost to sell. At the time of transfer, write-downs on the loans are recorded as charge-offs, establishing a new cost basis upon transfer.
Loans Held for Investment
Loans Held for Investment: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered held for investment. Loans originated by Seacoast and held for investment are recognized at the principal amount outstanding, net of unearned income and amounts charged off. Unearned income includes discounts, premiums and deferred loan origination fees reduced by loan origination costs. Unearned income on loans is amortized to interest income over the life of the related loan using the effective interest rate method. Interest income is recognized on an accrual basis.
As a part of business acquisitions, the Company acquires loans that are recorded at fair value on the acquisition date. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date. Any losses after acquisition are recognized through the allowance for credit losses. 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 that do not meet the definition of PCD are classified by the Company as acquired Non-PCD. An allowance for expected credit losses on PCD loans is recorded at the date of acquisition through an adjustment to the loans' amortized cost basis. In contrast, expected credit losses on loans not considered PCD are recognized through the provision for credit losses in net income at the date of acquisition.
The accrual of interest is generally discontinued on loans, except consumer loans, that become 90 days past due as to principal or interest unless collection of both principal and interest is assured by way of collateralization, guarantees or other security. When interest accruals are discontinued, unpaid interest is reversed against interest income. Consumer loans that become 120 days past due are generally charged off. When borrowers demonstrate over an extended period the ability to repay a loan in accordance with the contractual terms of a loan classified as nonaccrual, the loan is returned to accrual status. Interest income on nonaccrual loans is either recorded using the cash basis method of accounting or recognized after the principal has been reduced to zero, depending on the type of loan. 
In response to the COVID-19 pandemic beginning in early 2020, rules defined in the Coronavirus Aid, Relief and Economic Security (“CARES”) Act and a joint statement issued by federal regulators in consultation with FASB provide financial institutions with the option not to apply troubled debt restructure (“TDR”) accounting to eligible loan modifications provided to borrowers affected by the economic impact of the COVID-19 pandemic. Outside of this guidance, 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 determined by discounting the expected future cash flows at the original interest rate of the loan.
It is the Company's practice to ensure that the charge-off policy meets or exceeds regulatory minimums. Losses on unsecured consumer loans are recognized at 90 days past due, compared to the regulatory loss criteria of 120 days. In compliance with Federal Financial Institution Examination Council guidelines, secured consumer loans, including residential real estate, are typically charged-off or charged down between 120 and 180 days past due, depending on the collateral type. Commercial loans and real estate loans are typically placed on nonaccrual status when principal or interest is past due for 90 days or more, unless the loan is both secured by collateral having realizable value sufficient to discharge the debt in-full and the loan is in process of collection. Secured loans may be charged-down to the estimated value of the collateral with previously accrued unpaid interest reversed against interest income. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects. Initial charge-off amounts are based on valuation estimates derived from appraisals, broker price opinions, or other market information. Generally, new appraisals are not received until the foreclosure process is completed; however, collateral values are evaluated periodically based on market information and incremental charge-offs are recorded if it is determined that collateral values have declined from their initial estimates.
Derivative Instruments and Hedging Activities
Derivative Instruments and Hedging Activities: The Company enters into derivative contracts, including swaps and floors, to meet the needs of customers who request such services and to manage the Company's exposure to interest rate fluctuations. Derivative contracts are carried at fair value and recorded in the consolidated balance sheet within other assets or other liabilities. The gain or loss resulting from changes in the fair value of interest rate swaps designated and qualifying as cash flow hedging instruments is initially reported as a component of other comprehensive income and subsequently reclassified into earnings through interest income in the same period in which the hedged transaction affects earnings.
The Company discontinues hedge accounting prospectively when it is determined that the derivative contract is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is terminated, management determines that the designation of the derivative as a hedging instrument is no longer appropriate or, for a cash flow hedge, the occurrence of the forecasted transaction is no longer probable. When hedge accounting on a cash flow hedge is discontinued, any subsequent changes in fair value of the derivative are recognized in earnings. The cumulative unrealized gain or loss related to a discontinuing cash flow hedge continues to be reported in AOCI and is subsequently reclassified into earnings in the same period in which the hedged transactions affects earnings, unless it is probable that the forecasted transaction will not occur by the end of the originally specified time period, in which case the cumulative unrealized gain or loss in AOCI is reclassified into earnings immediately.
Cash flows resulting from derivative financial instruments that are accounted for as hedges are classified in the cash flow statement in the same category as the cash flows from the hedged items.
See additional disclosures related to derivative instruments and hedging activities in “Note G – Derivatives”.
Loan Commitments and Letters of Credit Loan Commitments and Letters of Credit: Loan commitments and letters of credit are an off-balance sheet item and represent commitments to make loans or lines of credit available to borrowers. The face amount of these commitments represents an exposure to loss, before considering customer collateral or ability to repay. Such commitments are recognized as loans when funded. The Company estimates a reserve for potential losses on 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.Fees received for providing loan commitments and letters of credit that may result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to noninterest income as banking fees and commissions on a straight-line basis over the commitment period when funding is not expected.
Fair Value Measurements Fair Value Measurements: The Company measures or monitors the fair value of many of its assets and liabilities. Certain assets are measured on a recurring basis, including available-for-sale securities and loans held for sale. These assets are carried at fair value on the Company’s balance sheets. Additionally, fair value is measured on a non-recurring basis to evaluate assets or
liabilities for impairment or for disclosure purposes. Examples include collateral-dependent loans, OREO, loan servicing rights, goodwill, and long-lived assets.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value.
The Company applies the following fair value hierarchy:
Level 1 – Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts.
Level 2 – Assets and liabilities valued based on observable market data for similar instruments.
Level 3 – Assets and liabilities for which significant valuation assumptions are not readily observable in the market; instruments valued based on the best available data, some of which is internally-developed, and considers risk premiums that a market participant would require.
When determining the fair value measurements for assets and liabilities required or permitted to be recorded at and/or marked to fair value, the Company considers the principal market in which it would transact and considers 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. Nevertheless, certain assets and liabilities are not actively traded in observable markets and the Company must use alternative valuation techniques to derive a fair value measurement.
Bank Premises and Equipment Bank Premises and Equipment: Bank premises and equipment are stated at cost, less accumulated depreciation and amortization. Premises and equipment include certain costs associated with the acquisition of leasehold improvements. Depreciation and amortization are recognized principally by the straight-line method, over the estimated useful lives as follows: buildings - 25-40 years, leasehold improvements 5-25 years, furniture and equipment - 3-12 years. Leasehold improvements typically amortize over the shorter of lease terms or estimated useful life. Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are written down to fair value with a corresponding impact to noninterest expense
Other Real Estate Owned
Other Real Estate Owned: Other real estate owned (“OREO”) consists primarily of real estate acquired in lieu of unpaid loan balances. These assets are carried at an amount equal to the loan balance prior to foreclosure plus costs incurred for improvements to the property, but no more than the estimated fair value of the property less estimated selling costs. Any valuation adjustments required at the date of transfer are charged to the allowance for credit losses. Subsequently, unrealized losses and realized gains and losses are included in other noninterest expense. Operating results from OREO are recorded in other noninterest expense.
OREO may also include bank premises no longer utilized in the course of the Company's business (closed branches) that are initially recorded at the lower of carrying value or fair value, less costs to sell. If fair value of the premises is less than amortized book value, a write down is recorded through noninterest expense. Costs to maintain the facility are expensed.
Intangible assets
Intangible assets. The Company’s intangible assets consist of goodwill, core deposit intangibles (CDIs) and mortgage servicing rights. Goodwill results from business combinations and represents the difference between the purchase price and the fair value of net assets acquired. Goodwill may be adjusted for up to one year from the acquisition date in the event new information is obtained which, if known at the date of acquisitions would have impacted the fair value of the acquired assets and liabilities. Goodwill is considered to have an indefinite useful life and is not amortized, but rather tested for impairment annually in the fourth quarter, or more often if circumstances arise that may indicate risk of impairment. If impaired, goodwill is written down with a corresponding impact to noninterest expense.
The Company recognizes CDIs that result from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over periods ranging from six to eight years on a straight line basis. The Company evaluates CDIs for impairment annually, or more often if circumstances arise that may indicate risk of impairment. If impaired, the CDI is written down with a corresponding impact to noninterest expense.
Bank owned life insurance (BOLI) Bank owned life insurance (BOLI): The Company, through its subsidiary bank, has purchased or acquired through bank acquisitions, life insurance policies on certain key executives. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Leases Leases: Arrangements are analyzed at inception to determine the existence of a lease. Right-of-use assets (ROUAs) represent the right to use the underlying asset and lease liabilities represent the 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 the Company's leases do not provide an implicit rate, the Company uses its 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 the option will be exercised. 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 and is classified as Occupancy or Furniture and Equipment expense based on the subject asset.
Revenue Recognition
Revenue Recognition: Revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the services provided and is recognized when the promised services (performance obligations) are transferred to a customer, requiring the application of the following five-steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation.
Relevant activity includes:
Service Charges on Deposits: Seacoast Bank offers a variety of deposit-related services to its customers through several delivery channels including branch offices, ATMs, telephone, mobile, and internet banking. Transaction-based fees are recognized when services, each of which represents a performance obligation, are satisfied. Service fees may be assessed monthly, quarterly, or annually; however, the account agreements to which these fees relate can be canceled at any time by Seacoast and/or the customer. Therefore, the contract term is considered a single day (a day-to-day contract).
Wealth Management Income: The Company earns trust fees from fiduciary services provided to trust customers, which include custody of assets, recordkeeping, collection and distribution of funds. Fees are earned over time and accrued monthly as the Company provides services, and are generally assessed based on the market value of the trust assets under management at a particular date or over a particular period. The Company also earns commissions and fees from investment brokerage services provided to its customers through an arrangement with a third-party service provider. Commissions received from the third-party service provider are recorded monthly and are based upon customer activity. Fees are earned over time and accrued monthly as services are provided. The Company acts as an agent in this arrangement and therefore presents the brokerage commissions and fees net of related costs.
•Interchange Income: Fees earned on card transactions depend upon the volume of activity, as well as the fees permitted by the payment network. Such fees are recognized by the Company upon fulfilling its performance obligation to approve the card transaction.
Treasury Stock Treasury Stock: The Company's repurchase of shares of its common stock are recorded at cost as treasury stock and result in a reduction of shareholders' equity. Activity in treasury stock represents shares traded to offset employee payroll taxes on vested shares. Shares held in treasury are used for employee share purchases through the Company's stock purchase plan.
Stock-Based Compensation Stock-Based Compensation: The stock option plans are accounted for under ASC Topic 718 - Compensation - Stock Compensation and the fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with market assumptions. This amount is amortized on a straight-line basis over the vesting period, generally 5 years. For restricted stock awards, which generally vest based on continued service with the Company, the deferred compensation is measured as the fair value of the shares on the date of grant, and the deferred compensation is amortized as salaries and employee benefits in accordance with the applicable vesting schedule, generally straight-line over three years. Some shares vest based upon the Company achieving certain performance goals and salary amortization expense is based on an estimate of the most likely results on a straight line basis. The Company accounts for forfeitures as they occur.
Income Taxes Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and their related tax bases and are measured using the enacted tax rates and laws that are in effect. A valuation allowance is recognized for a deferred tax asset if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. The effect on deferred tax assets and liabilities of a change in rates is recognized as income or expense in the period in which the change occurs.
Earnings per Share Earnings per Share: Basic earnings per share are computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share are based on the weighted-average number of common shares outstanding during each period, plus common share equivalents calculated for stock options and performance restricted stock outstanding using the treasury stock method.
