Accounting Policies [Abstract]
Significant Accounting Policies	Note A
	Significant Accounting Policies
	General: Seacoast Banking Corporation of Florida (“Company”) is a single segment bank holding company with one operating subsidiary bank, Seacoast National Bank (“Seacoast National”, together the “Company”). Seacoast National’s service area includes Okeechobee, Highlands, Hendry, Glades, DeSoto, Palm Beach, Martin, St. Lucie, Brevard, Indian River, Broward, Orange, Lake, Volusia and Seminole counties, which are located in central and southeast Florida. The bank operates full service branches within its markets, and during 2014 acquired 12 additional branches as part of the BANKshares acquisition.
	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.
	Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks, interest-bearing bank balances and federal funds sold and securities purchased under resale agreements. Cash and 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.
	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.
	Use of Estimates: The preparation of these financial statements requires the use of certain estimates by management in determining the Company's assets, liabilities, revenues and expenses, and contingent liabilities. Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, the valuation of investment securities available for sale, fair value of impaired loans, contingent liabilities, other real estate owned, and valuation of deferred tax valuation allowance. Actual results could differ from those estimates.
	Securities: Securities are classified at date of purchase as trading, available for sale or held to maturity. 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. 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. Debt securities that the Company has the ability and intent to hold to maturity are carried at amortized cost.
	Realized gains and losses, including other than temporary impairments, are included in noninterest income as investment securities gains (losses). Interest and dividends on securities, including amortization of premiums and accretion of discounts, 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.
	On a quarterly basis, the Company makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security is impaired on an other-than-temporary basis. Management considers many factors including the length of time the security has had a fair value less than the cost basis; our intent and ability to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, external credit ratings and recent downgrades. Securities on which there is an unrealized loss that is deemed to be other-than temporary are written down to fair value with the write-down recorded as a realized loss or if related to other factors are recorded as other comprehensive income.
	For securities which are transferred into held to maturity from available for sale the unrealized gain or loss at the date of transfer is reported as a component of shareholders’ equity and is amortized over the remaining life as an adjustment of yield using the interest method.
	Seacoast National is a member of the Federal Home Loan Bank system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value.  Both cash and stock dividends are reported as income.
	Loans: Loans 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.
	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.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered held for investment.
	The Company accounts for loans in accordance with ASC topics 310 and 470, when due to a deterioration in a borrower’s financial position, the Company grants concessions that would not otherwise be considered. Troubled debt restructured (TDR) loans are tested for impairment and placed in nonaccrual status. If borrowers perform pursuant to the modified loan terms for at least six months and the remaining loan balances are considered collectible, the loans are returned to accrual status. When the Company modifies the terms of an existing loan that is not considered a troubled debt restructuring, the Company follows the provisions of ASC 310 “Creditor’s Accounting for a Modification or Exchange of Debt Instruments.”
	A loan is considered to be impaired when based on current information; it is probable the Company will not receive all amounts due in accordance with the contractual terms of a loan agreement. The fair value is measured based on either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. A loan is also considered impaired if its terms are modified in a troubled debt restructuring. When the ultimate collectibility of the principal balance of an impaired loan is in doubt, all cash receipts are applied to principal. Once the recorded principal balance has been reduced to zero, future cash receipts are applied to interest income, to the extent any interest has been forgone, and then they are recorded as recoveries of any amounts previously charged off.
	The accrual of interest is generally discontinued on loans and leases, 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. Generally, loans past due 90 days or more are placed on nonaccrual status regardless of 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.
	Purchased loans: As a part of business acquisitions, the Company acquires loans, some of which have shown evidence of credit deterioration since origination and others without specifically identified credit deficiency factors. These acquired loans were recorded at the acquisition date fair value, and after acquisition, any losses are recognized through the allowance for loan losses. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date.
	These loans fall into two groups: purchased credit-impaired (“PCI”) and purchased unimpaired loans (“PUL”). The Company estimates the amount and timing of expected cash flows for each PUL and the expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan. The PUL’s were evaluated to determine estimated fair values as of the acquisition date. Based on management’s estimate of fair value, each PUL was assigned a discount credit mark.
	For PCI loans the Company updates the amount of loan principal and interest cash flows expected to be collected, incorporating assumptions regarding default rates, loss severities, the amounts and timing of prepayments and other factors that are reflective of current market conditions on a quarterly basis. Probable decreases in expected loan principal cash flows trigger the recognition of impairment, which is then measured as the present value of the expected principal loss plus any related foregone interest cash flows discounted at the loan’s effective interest rate. Impairments that occur after the acquisition date are recognized through the provision for loan losses. Probable and significant increases in expected principal cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income. The impacts of (i) prepayments, (ii) changes in variable interest rates, and (iii) any other changes in the timing of expected cash flows are recognized prospectively as adjustments to interest income. Disposals of loans, which may include sales of loans, receipt of payments in full by the borrower, or foreclosure, result in removal of the loan from the purchased credit impaired portfolio. In contrast, PUL’s are evaluated using the same procedures as used for the Company’s non-purchased loan portfolio.
	Derivatives Used for Risk Management: The Company may designate a derivative as either a hedge of the fair value of a recognized fixed rate asset or liability or an unrecognized firm commitment (“fair value” hedge), a hedge of a forecasted transaction or of the variability of future cash flows of a floating rate asset or liability (“cash flow” hedge). All derivatives are recorded as other assets or other liabilities on the balance sheet at their respective fair values with unrealized gains and losses recorded either in other comprehensive income or in the results of operations, depending on the purpose for which the derivative is held. Derivatives that do not meet the criteria for designation as a hedge at inception, or fail to meet the criteria thereafter, are carried at fair value with unrealized gains and losses recorded in the results of operations.
	To the extent of the effectiveness of a cash flow hedge, changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge are recorded in other comprehensive income. The net periodic interest settlement on derivatives is treated as an adjustment to the interest income or interest expense of the hedged assets or liabilities.
	At inception of a hedge transaction, the Company formally documents the hedge relationship and the risk management objective and strategy for undertaking the hedge. This process includes identification of the hedging instrument, hedged item, risk being hedged and the methodology for measuring ineffectiveness. In addition, the Company assesses both at the inception of the hedge and on an ongoing quarterly basis, whether the derivative used in the hedging transaction has been highly effective in offsetting changes in fair value or cash flows of the hedged item, and whether the derivative as a hedging instrument is no longer appropriate.
	The Company discontinues hedge accounting prospectively when either it is determined that the derivative is no longer highly effective in offsetting changes in the fair value or cash flows of a hedged item; the derivative expires or is sold, terminated or exercised; the derivative is de-designated because it is unlikely that a forecasted transaction will occur; or management determines that designation of the derivative as a hedging instrument is no longer appropriate.
	When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted as an adjustment to yield over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transaction are still expected to occur, unrealized gains and losses that are accumulated in other comprehensive income are included in the results of operations in the same period when the results of operations are also affected by the hedged cash flow. They are recognized in the results of operations immediately if the cash flow hedge was discontinued because a forecasted transaction is not expected to occur.
	Certain commitments to sell loans are derivatives. These commitments are recorded as a freestanding derivative and classified as an other asset or liability.
	Loans Held for Sale: Loans are classified as held for sale based on management’s intent to sell the loans, either as part of a core business strategy or related to a risk mitigation strategy. Loans held for sale and any related unfunded lending commitments are recorded at fair value, if elected or the lower of cost (which is the carrying amount net of deferred fees and costs and applicable allowance for loan losses and reserve for unfunded lending commitments) or fair market value less costs to sell. Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as noninterest income in the Consolidated Statements of Income. At the time of the transfer to loans held for sale, if the fair market value is less than cost, the difference is recorded as additional provision for credit losses in the results of operations. Fair market value is determined based on quoted market prices for the same or similar loans, outstanding investor commitments or discounted cash flow analyses using market assumptions.
	Fair market value for substantially all the loans in loans held for sale were obtained by reference to prices for the same or similar loans from recent transactions. For a relationship that includes an unfunded lending commitment, the cost basis is the outstanding balance of the loan net of the allowance for loan losses and net of any reserve for unfunded lending commitments. This cost basis is compared to the fair market value of the entire relationship including the unfunded lending commitment.
	Individual loans or pools of loans are transferred from the loan portfolio to loans held for sale when the intent to hold the loans has changed and there is a plan to sell the loans within a reasonable period of time. Loans held for sale are reviewed quarterly. Subsequent declines or recoveries of previous declines in the fair market value of loans held for sale are recorded in other fee income in the results of operations. 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. If an unfunded lending commitment expires before a sale occurs, the reserve associated with the unfunded lending commitment is recognized as a credit to other fee income in the results of operations.
	Fair Value Measurements: The Company measures or monitors many of its assets and liabilities on a fair value basis. Certain assets and liabilities are measured on a recurring basis. Examples of these include derivative instruments, available for sale and trading securities, loans held for sale and long-term debt. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. Examples of these non-recurring uses of fair value include certain loans held for sale accounted for on a lower of cost or fair value, mortgage 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 applied 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 or most advantageous 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.
	Other Real Estate Owned: Other real estate owned (“OREO”) consists 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 loan 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.
	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. 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 recorded at fair value.
	Intangible Assets: Mergers and acquisitions are accounted for using the acquisition method of accounting, which requires that acquired assets and liabilities are recorded at their fair values. This often involves estimates based on third party valuations or internal valuations based on discounted cash flow analyses or other valuation techniques, all of which are inherently subjective. The amortization of identified intangible assets is based upon the estimated economic benefits to be received, which is also subjective.
	Goodwill resulting from business combinations is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected October 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the Company’s balance sheet.
	The core deposit intangibles are intangible assets arising from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over a seven-year period on a straight line basis. The Company periodically evaluates whether events and circumstances have occurred that may affect the estimated useful lives or the recoverability of the remaining balance of the intangible assets.
	Bank owned life insurance (BOLI): The Company, through its subsidiary bank, has purchased life insurance policies on certain key executives. Bank owned life insurance 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.
	Revenue Recognition: Revenue is recognized when the earnings process is complete and collectibility is assured. Brokerage fees and commissions are recognized on a trade date basis. Asset management fees, measured by assets at a particular date, are accrued as earned. Commission expenses are recorded when the related revenue is recognized.
	Allowance for Loan Losses and Reserve for Unfunded Lending Commitments: The Company has developed policies and procedures for assessing the adequacy of the allowance for loan losses and reserve for unfunded lending commitments that reflect the evaluation of credit risk after careful consideration of all available information. Where appropriate this assessment includes monitoring qualitative and quantitative trends including changes in levels of past due, criticized and nonperforming loans. In developing this assessment, the Company must necessarily rely on estimates and exercise judgment regarding matters where the ultimate outcome is unknown such as economic factors, developments affecting companies in specific industries and issues with respect to single borrowers. Depending on changes in circumstances, future assessments of credit risk may yield materially different results, which may result in an increase or a decrease in the allowance for loan losses.
	The allowance for loan losses and reserve for unfunded lending commitments is maintained at a level the Company believes is adequate to absorb probable losses incurred in the loan portfolio and unfunded lending commitments as of the date of the consolidated financial statements. The Company employs a variety of modeling and estimation tools in developing the appropriate allowance for loan losses and reserve for unfunded lending commitments. The allowance for loan losses and reserve for unfunded lending commitments consists of formula-based components for both commercial and consumer loans, allowance for impaired commercial loans and allowance related to additional factors that are believed indicative of current trends and business cycle issues.
	If necessary, a specific allowance is established for individually evaluated impaired loans. The specific allowance established for these loans is based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated market value, or the estimated fair value of the underlying collateral depending on the most likely source of repayment. General allowances are established for loans grouped into pools based on similar characteristics. In this process, general allowance factors are based on an analysis of historical charge-off experience, portfolio trends, regional and national economic conditions, and expected loss given default derived from the Company’s internal risk rating process.
	The Company monitors qualitative and quantitative trends in the loan portfolio, including changes in the levels of past due, criticized and nonperforming loans. The distribution of the allowance for loan losses and reserve for unfunded lending commitments between the various components does not diminish the fact that the entire allowance for loan losses and reserve for unfunded lending commitments is available to absorb credit losses in the loan portfolio. The principal focus is, therefore, on the adequacy of the total allowance for loan losses and reserve for unfunded lending commitments.
	In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s bank subsidiary’s allowance for loan losses and reserve for unfunded lending commitments. These agencies may require such subsidiaries to recognize changes to the allowance for loan losses and reserve for unfunded lending commitments based on their judgments about information available to them at the time of their examination.
	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. See Note L, Income Taxes for related disclosures.
	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.
	Stock-Based Compensation: The stock option plans are accounted for under ASC Topic 718 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 five years. (See Note J)
	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 five 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.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Standards, Not Adopted as of December 31, 2014	Note B
	Recently Issued Accounting Standards, Not Adopted as of December 31, 2014
	Accounting Standards Update No. 2014-04 - Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure – In January 2014, FASB issued ASU 2014-04. This amendment is intended to reduce diversity in practice by clarifying when an in substance repossession or foreclosure occurs, and when a creditor should be considered to have received physical possession of residential real estate property. The Update also defines when the accounting change for the loan should take place.
	The amendments in this Update are effective for fiscal years beginning after December 15, 2014. Early adoption is permitted. The Company will adopt the methodologies prescribed by this ASU by the date required, and does not anticipate that the ASU will have a material effect on its financial position or results of operations.
	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-08 (ASU 2014-08) “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. We do not expect the impact of the adoption of ASU 2014-08 to be material to our consolidated financial statements.
	Accounting Standards Update No. 2014-09 - Revenue from Contracts with Customers (Topic 606). In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09. The ASU is a converged standard between the FASB and the IASB that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The primary objective of the ASU is revenue recognition that represents the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU is effective for interim and annual reporting periods beginning after December 15, 2016. The Company is currently assessing the impact of adoption of ASU 2014-09.
	In June 2014, the FASB issued Accounting Standards Update No. 2014-10 (ASU 2014-10) "Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation". ASU 2014-10 removes the definition of a development stage entity from the Master Glossary of the ASC thereby removing the financial reporting distinction between development stage entities and other reporting entities. The amendment eliminating the exception to the sufficiency-of-equity-at-risk criterion for development stage entities should be applied retrospectively for annual reporting periods beginning after December 15, 2015, and interim periods therein. Early application of these amendments is permitted. We do not expect the impact of the adoption of ASU 2014-10 to be material to our consolidated financial statements.
	Accounting Standards Update No. 2014-11 - Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. In June 2014, the FASB issued ASU No. 2014-11. This ASU requires secured borrowing accounting treatment for repurchase-to-maturity transactions and provides guidance on accounting for repurchase financing arrangements. This ASU is effective for interim and annual reporting periods beginning after December 15, 2014. The adoption of this ASU will result in additional disclosures, but is not expected to impact significantly the Company’s consolidated financial position or results of operations.
	Accounting Standards Update No. 2014-12 - Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period. In June 2014, the FASB issued ASU No. 2014-12. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and should not be reflected in estimating the grant-date fair value of the award. This ASU is effective for interim and annual reporting periods beginning after December 15, 2015 with earlier adoption permitted. The adoption of this ASU is not expected to impact significantly the Company’s consolidated financial position or results of operations.
	FASB issued Accounting Standards Update 2014-14 - Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. This update requires creditors to reclassify loans that are within the scope of the ASU to “other receivables” upon foreclosure, rather than reclassifying them to other real estate owned. The separate other receivable recorded upon foreclosure is to be measured based on the amount of the loan balance (principal and interest) the creditor expects to recover from the guarantor. The new guidance is effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The impact of adoption of this ASU by the Company is not expected to impact significantly the Company’s consolidated financial position or results of operations.

Cash, Dividend and Loan Restrictions [Abstract]
Cash, Dividend and Loan Restrictions	Note C Cash, Dividend and Loan Restrictions
	In the normal course of business, the Company and Seacoast National 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 National is required to maintain average reserve balances with the Federal Reserve Bank. The average amount of those reserve balances was $56.6 million for 2014 and $75.4 million for 2013.
	Under Federal Reserve regulation, Seacoast National 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, 2014, the maximum amount available for transfer from Seacoast National to the Company in the form of loans approximated $41.8 million.
	The approval of the Office of the Comptroller of the Currency (“OCC”) is required if the total of all dividends declared by a national bank in any calendar year exceeds the bank's profits, as defined, for that year combined with its retained net profits for the preceding two calendar years. Under this restriction Seacoast National can distribute dividends of approximately $59.0 million to the Company as of December 31, 2014, without prior approval of the OCC.

	Securities with a carrying and fair value of $107,660,000 and $107,500,000, respectively, at December 31, 2014, were pledged as collateral for United States Treasury deposits, other public deposits and trust deposits. Securities with a carrying and fair value of $232,677,000 and $227,620,000, respectively, were pledged as collateral for repurchase agreements.
	On May 31, 2014, management identified $158.8 million of investment securities available for sale and transferred them to held for investment. The unrealized holding losses at the date of transfer totaled $3.1 million. The securities that were transferred into the held for investment category from the available for sale category, the unrealized losses at the date of transfers will continue to be reported in other comprehensive income, and will be amortized over the remaining life of the secuiruty as an adjustment of yield consistent with the amortization of a discount. The amortization of unrealized holding losses reported in equity will offset the effect or interest income of the amortization of the discount.
	The amortized cost and fair value of securities at December 31, 2014, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or repay obligations with or without call or prepayment penalties.

At December 31, 2014, approximately $1.1 million of the unrealized losses pertain to private label securities secured by collateral originated in 2005 and prior. Their fair value is $71.6 million and is attributable to a combination of factors, including relative changes in interest rates since the time of purchase. The collateral underlying these mortgage investments are 30- and 15-year fixed and 10/1 adjustable rate mortgage loans with low loan to values, subordination and historically have had minimal foreclosures and losses. Based on its assessment of these factors, management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest rate movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.
At December 31, 2014, the Company also had $6.8 million of unrealized losses on collateralized mortgage obligations and mortgage backed securities of government sponsored entities having a fair value of $329.1 million that were attributable to a combination of factors, including relative changes in interest rates since the time of purchase. The contractual cash flows for these securities are guaranteed by U.S. government agencies and U.S. government-sponsored enterprises. Based on its assessment of these factors , management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.
At December 31, 2014, the Company also had $2.2 million of unrealized losses on collateralized loan obligations having a fair value of $125.2 million that were attributable to a combination of factors, including relative changes in interest rates, spreads and interest movements since the time of purchase. Based on its assessment of these factors, management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.
As of December 31, 2014, management does not intend to sell securities that are in unrealized loss positions and it is not more likely than not that the Company will be required to sell these securities before recovery of the amortized cost basis. Therefore, management does not consider any investment to be other-than-temporarily impaired at December 31, 2014.
Included in other assets is $16.3 million of Federal Home Loan Bank and Federal Reserve Bank stock stated at par value. At December 31, 2014, the Company has not identified events or changes in circumstances which may have a significant adverse effect on the fair value of the $16.3 million of cost method investment securities.

	Purchased Loans PCI loans are accounted for pursuant to ASC Topic 310-30. The excess of cash flows expected to be collected over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan in situations where there is a reasonable expectation about the timing and amount of cash flows expected to be collected. The difference between the contractually required payments and the cash flows expected to be collected at acquisition, considering the impact of prepayments, is referred to as the nonaccretable difference.
	We have applied ASC Topic 310-20 accounting treatment to PULs. The unamortized credit mark established at acquisition on the loans has been ascribed as an accretable yield that is accreted into interest income over the estimated remaining life of the loans.
	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 the acquisition date. Contractually required principal and interest payments have been adjusted for estimated prepayments.

	One of the sources of the Company's business is loans to directors and executive officers. The aggregate dollar amount of these loans was approximately $4,514,000 and $4,771,000 at December 31, 2014 and 2013, respectively. During 2014 new loans totaling $867,000 were made and reductions totaled $1,173,000.
	At December 31, 2014 and 2013 loans pledged as collateral for borrowings totaled $130 million and  $50.0 million, respectively.
	Loans are made to individuals, as well as, commercial and tax exempt entities.  Specific loan terms vary as to interest rate, repayment, and collateral requirements based on the type of loan requested and the credit worthiness of the prospective borrower.
	Concentrations of Credit All of the Company’s lending activity occurs within the State of Florida, including Orlando in Central Florida and Southeast coastal counties from Brevard County in the north to Palm Beach County in the south, as well as, all of the counties surrounding Lake Okeechobee in the center of the state. The Company’s loan portfolio consists of approximately one half commercial and commercial real estate loans and one half consumer and residential real estate loans.
	The Company’s extension of credit is governed by the Credit Risk Policy which was established to control the quality of the Company’s loans.  These policies and procedures are reviewed and approved by the Board of Directors on a regular basis.
	Construction and Land Development Loans  The Company defines construction and land development loans as exposures secured by land development and construction (including 1-4 family residential construction), multi-family property, and non-farm nonresidential property where the primary or significant source of repayment is from rental income associated with that property (that is, loans for which 50 percent or more of the source of repayment comes from third party, non-affiliated rental income) or the proceeds of the sale, refinancing, or permanent financing of the property.
	Commercial Real Estate Loans   The Company’s goal is to create and maintain a high quality portfolio of commercial real estate loans with customers who meet the quality and relationship profitability objectives of the Company.  Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans.  These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property.  Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type.
	Residential Real Estate Loans The Company selectively adds residential mortgage loans to its portfolio, primarily loans with adjustable rates, home equity mortgages and home equity lines. Substantially all residential originations have been underwritten to conventional loan agency standards, including loans having balances that exceed agency value limitations. The Company has never offered sub-prime, Alt A, Option ARM or any negative amortizing residential loans, programs or products, although we have originated and hold residential mortgage loans from borrowers with original or current FICO credit scores that are less than “prime.”
Commercial and Financial Loans   Commercial credit is extended primarily to small to medium sized professional firms, retail and wholesale operators and light industrial and manufacturing concerns.   Such credits typically comprise working capital loans, loans for physical asset expansion, asset acquisition and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the businesses’ major owners. Commercial loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower.  The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors.  Minimum standards and underwriting guidelines have been established for all commercial loan types.
Consumer Loans   The Company originates consumer loans including installment loans, loans for automobiles, boats, and other personal, family and household purposes. For each loan type several factors including debt to income, type of collateral and loan to collateral value, credit history and Company relationship with the borrower is considered during the underwriting process.

	-2	All purchased loans disclosed were acquired in 2014 and were therefore not presented as part of this table.
Nonaccrual loans and loans past due ninety days or more were $21.1 million and $27.8 million at December 31, 2014 and 2013, respectively.  The reduction in interest income associated with loans on nonaccrual status was approximately $1.9 million, $1.0 million, and $1.9 million, for the years ended December 31, 2014, 2013, and 2012, respectively.
The Company utilizes an internal asset classification system as a means of reporting problem and potential problem loans.  Under the Company’s risk rating system, the Company classifies problem and potential problem loans as “Special Mention,” “Substandard,” and “Doubtful” and these loans are monitored on an ongoing basis.  Substandard loans include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.  Loans classified as substandard may require a specific allowance, but generally does not exceed 30% of the principal balance. Loans classified as Doubtful, have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses present make 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 generally charged off. Loans that do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses that deserve management’s close attention are deemed to be Special Mention.  Risk ratings are updated any time the situation warrants.
Loans not meeting the criteria above are considered to be pass-rated loans and risk grades are recalculated at least annually by the loan relationship manager.   The following tables present the risk category of loans by class of loans based on the most recent analysis performed as of December 31, 2014 and 2013:

Impaired Loans and Allowance for Loan Losses	Note F    Impaired Loans and Allowance for Loan Losses
	During the twelve months ended December 31, 2014, the total of newly identified TDRs was $5.5 million, of which $4.3 million were accruing commercial real estate loans, $0.7 million were accruing residential real estate mortgage loans and $0.1 million were accruing construction and land development loans.
	The following table presents loans that were modified within the twelve months ending December 31, 2014:

	No accruing loans that were restructured within the twelve months ending December 31, 2014 defaulted during the twelve months ended December 31, 2014. The Company considers a loan to have defaulted when it becomes 90 or more days delinquent under the modified terms, has been transferred to non-accrual status or has been transferred to other real estate owned.
	At December 31, 2014 and 2013, the Company's recorded investment in impaired loans (excluding purchased loans) and related valuation allowance was as follows:

Impaired loans also include loans that have been modified in troubled debt restructurings where concessions to borrowers who experienced financial difficulties have been granted. At December 31, 2014 and 2013, accruing TDRs totaled $25.0 million and $25.1 million, respectively.
The average recorded investment in impaired loans for the years ended December 31, 2014, 2013 and 2012 was $49,602,000, $66,603,000 and $96,439,000, respectively. The impaired loans were measured or impairment based on the value of underlying collateral or the present value of expected future cash flows discounted at the loan's effective interest rate. The valuation allowance is included in the allowance for loan losses.
Interest payments received on impaired loans are recorded as interest income unless collection of the remaining recorded investment is doubtful at which time payments received are recorded as reductions to principal. For the years ended December 31, 2014, 2013 and 2012, the Company recorded $1,345,000, $1,260,000 and $3,054,000, respectively, in interest income on impaired loans.
For impaired loans whose impairment is measured based on the present value of expected future cash flows a total of $456,000, $1.1 million and $1.0 million, respectively, for 2014, 2013 and 2012 was included in interest income and represents the change in present value attributable to the passage of time.
The nonaccrual loans and accruing loans past due 90 days or more (excluding purchased loans) were $18,563,000 and $17,000, respectively, at December 31, 2014, $27,672,000 and $160,000, respectively at the end of 2013, and were $40,955,000 and $1,000, respectively, at year-end 2012.
The purchased nonaccrual loans and accruing loans past due 90 days or more were $2,576,000 and $323,000, respectively, at December 31, 2014. There were no purchased loans prior to 2014.
Activity in the allowance for loans losses (excluding PCI loans) for the three years ended December 31, 2014, 2013 and 2012 are summarized as follows:

Loans collectively evaluated for impairment reported at December 31, 2014 included loans acquired from BANKshares on October 1, 2014 that are not PCI loans. These loans are performing loans recorded at estimated fair value at the acquisition date. The fair value adjustment for loans acquired from BANKshares at the acquisition date was approximately $11.2 million, or approximately 3.56% of the outstanding aggregate loan balances. This amount, which represents the total fair value discount of each PUL, is accreted into interest income over the remaining lives of the related loans on a level yield basis, and remains adequate at December 31,2014, and therefore no provision for loan loss was recorded related to these loans at December 31, 2014. The table below summarizes PCI loans that were individually evaluated for impairment based on expected cash flows.

	During 2007, the Company obtained advances from the Federal Home Loan Bank (FHLB) of $25,000,000 each on September 25, 2007 and November 27, 2007. The advances mature on September 15, 2017 and November 27, 2017, respectively, and have fixed rates of 3.64 percent and 2.70 percent at December 31, 2014, respectively, payable quarterly; the FHLB has a perpetual three-month option to convert the interest rate on either advance to an adjustable rate and the Company has the option to prepay the advance should the FHLB convert the interest rate.
	Seacoast National has unused secured lines of credit of $1,259,345,000 at December 31, 2014.
	The Company issued $20,619,000 in junior subordinated debentures on March 31 and December 16, 2005, an aggregate of $41,238,000. These debentures were issued in conjunction with the formation of a Delaware and Connecticut trust subsidiary, SBCF Capital Trust I, and SBCF Statutory Trust II ("Trusts I and II") which each completed a private sale of $20.0 million of floating rate preferred securities. On June 29, 2007, the Company issued an additional $12,372,000 in junior subordinated debentures which was issued in conjunction with the formation of a Delaware trust subsidiary, SBCF Statutory Trust III ("Trust III"), which completed a private sale of $12.0 million of floating rate trust preferred securities. The rates on the trust preferred securities are the 3-month LIBOR rate plus 175 basis points, the 3-month LIBOR rate plus 133 basis points, and the 3-month LIBOR rate plus 135 basis points, respectively. The rates, which adjust every three months, are currently  2.01 percent, 1.57 percent, and 1.59 percent, respectively, per annum. The trust preferred securities have original maturities of thirty years, and may be redeemed without penalty on or after June 10, 2010, March 15, 2011, and September 15, 2012, respectively, 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 Trusts also issued $619,000, $619,000 and $372,000, respectively, of common equity securities to the Company. The proceeds of the offering of trust preferred securities and common equity securities were used by Trusts I and II to purchase the $41.2 million junior subordinated deferrable interest notes issued by the Company, and by 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.
	As part of the October 1, 2014 BANKshares acquisition the Company acquired three junior subordinated debentures. Correspondingly, at December 31, 2014 the Company has $5,155,000 and $4,124,000 of Floating Rate Junior Subordinated Deferrable Interest Debentures outstanding which are due December 26, 2032 and March 17, 2034, and callable by the Company, at its option, any time after December 26, 2007 and March 17, 2009. The rates on these trust preferred securities are the 3-month LIBOR rate plus 325 basis points and the 3-month LIBOR rate plus 279 basis points, respectively. The rates, which adjust every three months, are currently 3.50 percent and 3.03 percent, respectively, per annum. At December 31, 2014 the Company has $5,155,000 outstanding of Junior Subordinated Debentures due February 23, 2036. The interest rate was fixed at 6.37 percent through February 2011 and thereafter, and the coupon rate floats quarterly at the three month LIBOR rate plus 139 basis points. The junior subordinated debenture is redeemable in certain circumstances after February 2011. The interest rate was 1.62 percent at December 31, 2014. The above three junior subordinated debentures in accordance with ASU 805 Business Combinations have been recorded at their acquisition date fair values which collectively is $3.5 million lower than face value and will be amortized into interest expense over the remaining term to maturity.
	The Company has the right to defer payments of interest on the notes at any time or from time to time for a period of up to twenty consecutive quarterly interest payment periods. Under the terms of the notes, in the event that under certain circumstances there is an event of default under the notes or the Company has elected to defer interest on the notes, the Company 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, 2014, 2013 and 2012, 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.

Employee Benefits and Stock Compensation

Note J

Employee Benefits and Stock Compensation

The Company’s profit sharing and retirement plan covers substantially all employees after one year of service and includes a matching benefit feature for employees electing to defer the elective portion of their profit sharing compensation. In addition, amounts of compensation contributed by employees are matched on a percentage basis under the plan. The profit sharing and retirement contributions charged to operations were $1,198,000 in 2014, $807,000 in 2013, and $771,000 in 2012.

The Company’s stock option and stock appreciation rights plans were approved by the Company’s shareholders on April 25, 1991, April 25, 1996, April 20, 2000, May 8, 2008 and May 23, 2013. The number of shares of common stock that may be granted pursuant to the 1991 and 1996 plans shall not exceed 198,000 shares for each plan, pursuant to the 2000 plan shall not exceed 264,000 shares, pursuant to the 2008 plan shall not exceed 300,000 shares, and pursuant to the 2013 plan shall not exceed 1,300,000 shares. The Company has granted options and stock appreciation rights (“SSARs”) on 166,000, 187,000, and 158,000 shares for the 1991, 1996, and 2000 plans, respectively, through December 31, 2014; no options or SSARs have been granted under the 2008 plan and  462,000 shares have been granted under the 2013 plan. Under the 2008 plan the Company issued 229,000 of restricted stock awards at $7.10 per share during 2011 and 15,000 of restricted stock awards at $8.10 per share during 2012. Under the 2013 plan, the Company issued 195,000 of restricted stock units at $11.00 per share during 2013 and 28,000 of restricted stock units at $10.19 per share during 2014. The restricted stock units allow the grantee to earn 0-160 percent of the target award as determined by two criteria, the Company’s after-tax earnings and its classified assets ratio. Any restricted stock units that become eligible for vesting pursuant to the performance requirements will vest by one-third on each of the first, second and third anniversaries of the last day of the performance period, December 31, 2016, 2017 and 2018, respectively. If the Company does not achieve the target performance goal for both criteria by December 31, 2015, then none of the restricted stock units will vest and they will be forfeited. Under the plans, the options, stock awards, SSARs or restricted stock units’ exercise price equals the common stock’s market price on the date of the grant. All options or SSARs issued after December 31, 2002 have a vesting period of three to five years and a contractual life of ten years. All stock awards and restricted stock units have a contractual life of three or five years. To the extent the Company has treasury shares available, stock options exercised or stock grants awarded may be issued from treasury shares or, if treasury shares are insufficient, the Company can issue new shares. The Company has a single share repurchase program in place, approved on September 18, 2001, authorizing the repurchase of up to 165,000 shares. On May 20, 2014 the Company authorized an additional 250,000 shares for the repurchase program; the maximum number of shares that may yet be purchased under these programs is 237,000.

The Company granted stock options totaling 413,000 shares in 2014 and 49,000 shares in 2013 at weighted average fair value per share of $2.26 and $3.10, respectively, but did not grant any stock options or SSARs in 2012. Stock option fair value is measured on the date of grant using the Black-Scholes option pricing model with market assumptions. Option pricing models require the use of highly subjective assumptions, including expected price volatility, which when changed can materially affect fair value estimates. Accordingly, the model does not necessarily provide a reliable single measure of the fair value of the Company’s stock options or SSARs. The more significant assumptions used in estimating the fair value of stock options granted in 2014 include: a weighted average risk-free interest rate of 2.7 percent; no dividends; weighted average expected life of 5 years; and a weighted average volatility of the Company’s common stock of 17.0 percent. The 2014 estimated fair value of stock options was not reduced by an estimate of forfeiture experience due to the relatively small pool of stock option recipients and short vesting terms.

	At December 31, 2014, the Company's deferred tax assets of $66.8 million consists of approximately $52.6 million of net U.S. federal deferred tax assets and $14.2 million of net state deferred tax assets.
	Management assesses the necessity of a valuation allowance recorded against deferred tax assets at each reporting period. The determination of whether a valuation allowance for net deferred tax assets 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 deferred tax assets 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 confidently and 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 deferred tax asset.
	Management expects to realize the $66.8 million in net deferred tax assets well in advance of the statutory carryforward period. At December 31, 2014, approximately $38.7 million of deferred tax assets relate to federal net operating losses which will expire in annual installments beginning in 2029 through 2032. Additionally, $7.5 million of the deferred tax assets relate to state net operating losses which will expire in annual installments beginning in 2028 through 2034. Tax credit carryforwards at December 31, 2014 include federal alternative minimum tax credits totaling $2.1 million which have an unlimited carryforward period. Remaining deferred tax assets are not related to net operating losses or credits and therefore, have no expiration date.
	Prior to the third quarter of 2013, the Company was unable to conclude that there was sufficient evidence to support that the deferred tax asset was more likely than not realizable and to support the reversal of its deferred tax asset valuation allowance of $44.8 million. The deferred tax asset valuation allowance was reversed after the achievement of operating results for the third quarter and nine months of 2013 that demonstrated the continuation of increasing income before tax results.
	A valuation allowance could be required in future periods based on the assessment of positive and negative evidence. Management’s conclusion at December 31, 2014 that it is more likely than not that the net deferred tax asset of $66.8 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 deferred tax assets. Such an increase to the deferred tax asset valuation allowance could have a material adverse effect on the Company’s financial condition and results of operations.
	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, 2014.
	The Company has no unrecognized income tax benefits or provisions due to uncertain income tax positions. The Internal Revenue Service (IRS) examined the federal income tax returns for the years 2006, 2007, 2008 and 2009. The IRS did not propose any adjustments related to this examination. The following are the major tax jurisdictions in which the Company operates and the earliest tax year subject to examination:
	Jurisdiction		Tax Year
	United States of America		2011
	Florida		2011
	Income taxes related to securities transactions were $181,000, $162,000 and $2,939,000 in 2014, 2013 and 2012, respectively.

Equity [Abstract]
Shareholders' Equity	Note N    Shareholders' Equity
	The Company has reserved 300,000 common shares for issuance in connection with an employee stock purchase plan and 1,000,000 common shares for issuance in connection with an employee profit sharing plan. At December 31, 2014, an aggregate of 183,360 shares and 0 shares, respectively, have been issued as a result of employee participation in these plans.
	A 1 for 5 reverse stock split was effective as of December 13, 2013. Each five shares of the Company's common stock was automatically converted to one share of the Company's common stock. Any fractional post-split shares as a result of the reverse split were rounded up to the nearest whole post-split share. Shareholders of the Company previously authorized the Board of Directors to approve a reverse stock split at the annual meeting in May 2013. All share amounts have been restated for all years presented.
	In December 2008, in connection with the Troubled Asset Relief Program (TARP) Capital Purchase Program, established as part of the Emergency Economic Stabilization Act of 2008, the Company issued to the U.S. Treasury Department (U.S. Treasury) 2,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (“Series A Preferred Stock”) with a par value of $0.10 per share and a 10-year warrant to purchase approximately 117,925 shares of common stock at an exercise price of $31.80 per share. The proceeds received were allocated to the preferred stock and additional paid-in-capital based on their relative fair values. The Series A Preferred Stock initially paid quarterly dividends at a five percent annual rate that increased to nine percent after five years on a liquidation preference of $25,000 per share. Upon the request of the U.S. Treasury, at any time, the Company agreed to enter into a deposit arrangement pursuant to which the Series A Preferred Stock may be deposited and depository shares may be issued. The Company registered the Series A Preferred Stock, the warrant, the shares of common stock underlying the warrant and the depository shares, if any, for resale under the Securities Act of 1933. On March 28, 2012, the U.S. Treasury publicly offered through an auction process their investment in the Series A Preferred Stock. The auction concluded on April 3, 2012, thereby transferring all of the U.S. Treasury's ownership in the Series A Preferred Stock to third party investors. The warrant to purchase shares of common stock was acquired by the Company on May 30, 2012 for $81,000, including related expenses. On December 31, 2013, the full amount of the Series A Preferred Stock was redeemed at par for $50 million plus accrued dividends through the date of redemption of $319,000 .
	A common stock offering was completed during November 2013 adding $75 million to capital, with approximately $47 million (net of issuance costs) received during November 2013, and $25 million received in January 2014 from a single investor that was required to obtain approval of the Federal Reserve Bank for its investment. Of the funds received, $50 million was utilized to redeem the Series A Preferred Stock at December 31, 2013, with the remainder available for future growth and general corporate purposes.
	Holders of common stock are entitled to one vote per share on all matters presented to shareholders as provided in the Company’s Articles of Incorporation. The Company implemented a dividend reinvestment plan during 2007, issuing no shares from treasury stock during 2014 and 2013.
	The Company was subject to certain standards for executive compensation while its preferred shares were owned by the U.S. Treasury that included (a) prohibiting “golden parachute” payments as defined in the Emergency Economic Stabilization Act of 2008 (EESA) to senior executive officers; (b) requiring recovery of any compensation paid to senior executive officers based on criteria that is later proven to be materially inaccurate; (c) prohibiting incentive compensation that encourages unnecessary and excessive risks that threaten the value of the financial institution, and (d) accepting restrictions on the payment of dividends and the repurchase of common stock. Seacoast believes it complied with all TARP standards and restrictions during the time the Company was a participant.

	The Company is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company's assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. 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 and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital to average assets (as defined). Management believes, as of December 31, 2014, that the Company meets all capital adequacy requirements to which it is subject.
	The Company is well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Company must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth above. At December 31, 2014, the Company’s deposit-taking bank subsidiary met the capital and leverage ratio requirements for well capitalized banks.

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities and Commitments with Off-Balance Sheet Risk	Note P
	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. 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. Of the $238,130,000 in commitments to extend credit outstanding at December 31, 2014, $98,646,000 is secured by 1-4 family residential properties for individuals with approximately $10,052,000 at fixed interest rates ranging from 3.25 to 5.125%.
	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. The extent of collateral held for secured standby letters of credit at December 31, 2014 and 2013 amounted to $2,617,000 and $3,187,000 respectively.
	Unfunded limited partner equity commitments at December 31, 2014 totaled $3,715,000 that the Company has committed to small business investment companies under the SBIC Act to be used to provide capital to small businesses.

	Fair Value
	Fair Value Instruments Measured at Fair Value
	In certain circumstances, fair value enables the Company to more accurately align its financial performance with the market value of actively traded or hedged assets and liabilities. Fair values enable a company to mitigate the non-economic earnings volatility caused from financial assets and financial liabilities being carried at different bases of accounting, as well as to more accurately portray the active and dynamic management of a company’s balance sheet. ASC 820 provides additional guidance for estimating fair value when the volume and level of activity for an asset or liability has significantly decreased. In addition, it includes guidance on identifying circumstances that indicate a transaction is not orderly. Under ASC 820, fair value measurements for items measured at fair value on a recurring and nonrecurring basis at December 31, 2014 and 2013 included:

	(1) See Note E. Nonrecurring fair value adjustments to loans identified as impaired reflect full or partial write-downs that are based on the loan's observable market price or current appraised value of the collateral in accordance with ASC 310.
	(2) Fair value is measured on a nonrecurring basis in accordance with ASC 360.
	(3) See Note D for further detail of recurring fair value basis of individual investment categories.
	(4) Recurring fair value basis determined using observable market data.
	The fair value of impaired loans which are not troubled debt restructurings is based on recent real estate appraisals less estimated costs of sale. For residential real estate impaired loans, appraised values or internal evaluation are based on the comparative sales approach. These impaired loans are considered level 2 in the fair value hierarchy. For commercial and commercial real estate impaired 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, 2014 the range of capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 8.2%. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time. As such, the fair value of these impaired loans is considered level 3 in the fair value hierarchy.
	Fair value of available for sale securities are determined using valuation techniques for individual investments as described in Note A.
	When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of 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.
	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.
	During 2014, there were no transfers between level 1 and level 2 assets carried at fair value.
	For loans classified as level 3 the transfers in totaled $0.5 million consisting of loans that became impaired during 2014. Transfers out consisted of charge offs of $0.2 million, and loan foreclosures migrating to OREO and other reductions (including principal payments) totaling $5.2 million. No sales were recorded.
	Charge-offs recognized upon loan foreclosures are generally offset by general or specific allocations of the allowance for loan losses and generally do not, and did not during the reported periods, significantly impact the Company's provision for loan losses.
	For OREO classified as level 3 during 2014 transfers out totaled $2.3 million consisting of valuation write-downs of $0.3 million and sales of $2.0 million, and transfers in consisted of foreclosed loans totaling $2.9 million.
	The carrying amount and fair value of the Company's other significant financial instruments that are not measured at fair value on a recurring basis in the balance sheet as of December 31 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 cash equivalents, interest bearing deposits with other banks, federal funds purchased and securities sold under agreement to repurchase, maturing within 30 days.
	The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at December 31, 2014 and 2013:
	Securities: U.S. Treasury securities are reported at fair value utilizing Level 1 inputs. Other securities are reported at fair value utilizing Level 2 inputs. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things.
	The Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, the Company does not purchase investment portfolio securities that are esoteric or that have a complicated structure. The Company’s entire portfolio consists of traditional investments, the majority of which are U.S. Treasury obligations, federal agency bullet or mortgage pass-through securities, or general obligation or revenue based municipal bonds. Pricing for such instruments is fairly generic and is easily obtained. The fair value of the collateralized loan obligations are determined from broker quotes. From time to time, the Company will validate, on a sample basis, prices supplied by brokers and the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models.
	Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, 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, except residential mortgages, is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risks inherent in the loan. For residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusting for prepayment assumptions using discount rates based on secondary market sources. The estimated fair value is not an exit price fair value under ASC 820 when this valuation technique is used.
	Loans held for sale: Fair values are based upon estimated values to be received from independent third party purchasers.
	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.
Borrowings: The fair value of floating rate borrowings is the amount payable on demand at the reporting date. The fair value of fixed rate borrowings is estimated using the rates currently offered for borrowings of similar remaining maturities.
Subordinated debt: The fair value of the floating rate subordinated debt is estimated using discounted cash flow analysis, estimates of the Company’s current incremental borrowing rate for similar instruments and dealer quotes for similar debt.

	The Company, through its subsidiary bank, purchased The BANKshares Inc. (“BANKshares”) in Winter Park, Florida on October 1, 2014. The acquisition related costs were approximately $4,361,000 and these expenses are reported in noninterest expenses in the consolidated statement of income. As a result of this acquisition, the Company expects to further solidify its market share in the Florida market, expand its customer base to enhance deposit fee income, and leverage operating costs through economies of scale.
	The Company acquired 100% of the outstanding common stock of BANKshares. Each share of BANKshares common stock was exchanged for 0.4975 shares of the Company’s common stock. Based on the closing price of the Company’s common stock on September 30, 2014, the resulting purchase price was $76.8 million. The table below summarizes the purchase price calculation.

	The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. Both the purchased assets and liabilities assumed are recorded at their respective acquisition date fair values. Determining the fair values of assets and liabilities, especially the loan portfolio and foreclosed real estate, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.
	For the loans acquired we first, segregated all acquired loans with specifically identified credit deficiency factor(s). The factors we considered to identify loans as Purchase Credit Impaired (“PCI”) loans were all acquired loans that were non-accrual, 60 days or more past due, designated as Trouble Debt Restructured (“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, we are accounting for these loans pursuant to ASC Topic 310-30.
	Second, for those loans without specifically identified credit deficiency factors are referred to as Purchased Unimpaired Loans (“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. Based on management’s estimate of fair value, each of the PUL’s were assigned a discount credit mark. We have applied ASC Topic 310-20 accounting treatment to PULs.
	The operating results of the Company for the year ended December 31, 2014 includes the operating results of the acquired assets and assumed liabilities since the acquisition date of October 1, 2014.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
General	General: Seacoast Banking Corporation of Florida (“Company”) is a single segment bank holding company with one operating subsidiary bank, Seacoast National Bank (“Seacoast National”, together the “Company”). Seacoast National’s service area includes Okeechobee, Highlands, Hendry, Glades, DeSoto, Palm Beach, Martin, St. Lucie, Brevard, Indian River, Broward, Orange, Lake, Volusia and Seminole counties, which are located in central and southeast Florida. The bank operates full service branches within its markets, and during 2014 acquired 12 additional branches as part of the BANKshares acquisition.
	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.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks, interest-bearing bank balances and federal funds sold and securities purchased under resale agreements. Cash and 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.
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.
Use of Estimates	Use of Estimates: The preparation of these financial statements requires the use of certain estimates by management in determining the Company's assets, liabilities, revenues and expenses, and contingent liabilities. Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, the valuation of investment securities available for sale, fair value of impaired loans, contingent liabilities, other real estate owned, and valuation of deferred tax valuation allowance. Actual results could differ from those estimates.
Securities	Securities: Securities are classified at date of purchase as trading, available for sale or held to maturity. 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. 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. Debt securities that the Company has the ability and intent to hold to maturity are carried at amortized cost.
	Realized gains and losses, including other than temporary impairments, are included in noninterest income as investment securities gains (losses). Interest and dividends on securities, including amortization of premiums and accretion of discounts, 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.
	On a quarterly basis, the Company makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security is impaired on an other-than-temporary basis. Management considers many factors including the length of time the security has had a fair value less than the cost basis; our intent and ability to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, external credit ratings and recent downgrades. Securities on which there is an unrealized loss that is deemed to be other-than temporary are written down to fair value with the write-down recorded as a realized loss or if related to other factors are recorded as other comprehensive income.
	For securities which are transferred into held to maturity from available for sale the unrealized gain or loss at the date of transfer is reported as a component of shareholders’ equity and is amortized over the remaining life as an adjustment of yield using the interest method.
	Seacoast National is a member of the Federal Home Loan Bank system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value.  Both cash and stock dividends are reported as income.
Loans	Loans: Loans 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.
	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.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered held for investment.
	The Company accounts for loans in accordance with ASC topics 310 and 470, when due to a deterioration in a borrower’s financial position, the Company grants concessions that would not otherwise be considered. Troubled debt restructured (TDR) loans are tested for impairment and placed in nonaccrual status. If borrowers perform pursuant to the modified loan terms for at least six months and the remaining loan balances are considered collectible, the loans are returned to accrual status. When the Company modifies the terms of an existing loan that is not considered a troubled debt restructuring, the Company follows the provisions of ASC 310 “Creditor’s Accounting for a Modification or Exchange of Debt Instruments.”
	A loan is considered to be impaired when based on current information; it is probable the Company will not receive all amounts due in accordance with the contractual terms of a loan agreement. The fair value is measured based on either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. A loan is also considered impaired if its terms are modified in a troubled debt restructuring. When the ultimate collectibility of the principal balance of an impaired loan is in doubt, all cash receipts are applied to principal. Once the recorded principal balance has been reduced to zero, future cash receipts are applied to interest income, to the extent any interest has been forgone, and then they are recorded as recoveries of any amounts previously charged off.
	The accrual of interest is generally discontinued on loans and leases, 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. Generally, loans past due 90 days or more are placed on nonaccrual status regardless of 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.
Purchased loans	Purchased loans: As a part of business acquisitions, the Company acquires loans, some of which have shown evidence of credit deterioration since origination and others without specifically identified credit deficiency factors. These acquired loans were recorded at the acquisition date fair value, and after acquisition, any losses are recognized through the allowance for loan losses. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date.
	These loans fall into two groups: purchased credit-impaired (“PCI”) and purchased unimpaired loans (“PUL”). The Company estimates the amount and timing of expected cash flows for each PUL and the expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan. The PUL’s were evaluated to determine estimated fair values as of the acquisition date. Based on management’s estimate of fair value, each PUL was assigned a discount credit mark.
	For PCI loans the Company updates the amount of loan principal and interest cash flows expected to be collected, incorporating assumptions regarding default rates, loss severities, the amounts and timing of prepayments and other factors that are reflective of current market conditions on a quarterly basis. Probable decreases in expected loan principal cash flows trigger the recognition of impairment, which is then measured as the present value of the expected principal loss plus any related foregone interest cash flows discounted at the loan’s effective interest rate. Impairments that occur after the acquisition date are recognized through the provision for loan losses. Probable and significant increases in expected principal cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income. The impacts of (i) prepayments, (ii) changes in variable interest rates, and (iii) any other changes in the timing of expected cash flows are recognized prospectively as adjustments to interest income. Disposals of loans, which may include sales of loans, receipt of payments in full by the borrower, or foreclosure, result in removal of the loan from the purchased credit impaired portfolio. In contrast, PUL’s are evaluated using the same procedures as used for the Company’s non-purchased loan portfolio.
Derivatives Used for Risk Management	Derivatives Used for Risk Management: The Company may designate a derivative as either a hedge of the fair value of a recognized fixed rate asset or liability or an unrecognized firm commitment (“fair value” hedge), a hedge of a forecasted transaction or of the variability of future cash flows of a floating rate asset or liability (“cash flow” hedge). All derivatives are recorded as other assets or other liabilities on the balance sheet at their respective fair values with unrealized gains and losses recorded either in other comprehensive income or in the results of operations, depending on the purpose for which the derivative is held. Derivatives that do not meet the criteria for designation as a hedge at inception, or fail to meet the criteria thereafter, are carried at fair value with unrealized gains and losses recorded in the results of operations.
	To the extent of the effectiveness of a cash flow hedge, changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge are recorded in other comprehensive income. The net periodic interest settlement on derivatives is treated as an adjustment to the interest income or interest expense of the hedged assets or liabilities.
	At inception of a hedge transaction, the Company formally documents the hedge relationship and the risk management objective and strategy for undertaking the hedge. This process includes identification of the hedging instrument, hedged item, risk being hedged and the methodology for measuring ineffectiveness. In addition, the Company assesses both at the inception of the hedge and on an ongoing quarterly basis, whether the derivative used in the hedging transaction has been highly effective in offsetting changes in fair value or cash flows of the hedged item, and whether the derivative as a hedging instrument is no longer appropriate.
	The Company discontinues hedge accounting prospectively when either it is determined that the derivative is no longer highly effective in offsetting changes in the fair value or cash flows of a hedged item; the derivative expires or is sold, terminated or exercised; the derivative is de-designated because it is unlikely that a forecasted transaction will occur; or management determines that designation of the derivative as a hedging instrument is no longer appropriate.
	When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted as an adjustment to yield over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transaction are still expected to occur, unrealized gains and losses that are accumulated in other comprehensive income are included in the results of operations in the same period when the results of operations are also affected by the hedged cash flow. They are recognized in the results of operations immediately if the cash flow hedge was discontinued because a forecasted transaction is not expected to occur.
	Certain commitments to sell loans are derivatives. These commitments are recorded as a freestanding derivative and classified as an other asset or liability.
Loans Held for Sale	Loans Held for Sale: Loans are classified as held for sale based on management’s intent to sell the loans, either as part of a core business strategy or related to a risk mitigation strategy. Loans held for sale and any related unfunded lending commitments are recorded at fair value, if elected or the lower of cost (which is the carrying amount net of deferred fees and costs and applicable allowance for loan losses and reserve for unfunded lending commitments) or fair market value less costs to sell. Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as noninterest income in the Consolidated Statements of Income. At the time of the transfer to loans held for sale, if the fair market value is less than cost, the difference is recorded as additional provision for credit losses in the results of operations. Fair market value is determined based on quoted market prices for the same or similar loans, outstanding investor commitments or discounted cash flow analyses using market assumptions.
	Fair market value for substantially all the loans in loans held for sale were obtained by reference to prices for the same or similar loans from recent transactions. For a relationship that includes an unfunded lending commitment, the cost basis is the outstanding balance of the loan net of the allowance for loan losses and net of any reserve for unfunded lending commitments. This cost basis is compared to the fair market value of the entire relationship including the unfunded lending commitment.
	Individual loans or pools of loans are transferred from the loan portfolio to loans held for sale when the intent to hold the loans has changed and there is a plan to sell the loans within a reasonable period of time. Loans held for sale are reviewed quarterly. Subsequent declines or recoveries of previous declines in the fair market value of loans held for sale are recorded in other fee income in the results of operations. 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. If an unfunded lending commitment expires before a sale occurs, the reserve associated with the unfunded lending commitment is recognized as a credit to other fee income in the results of operations.
Fair Value Measurements	Fair Value Measurements: The Company measures or monitors many of its assets and liabilities on a fair value basis. Certain assets and liabilities are measured on a recurring basis. Examples of these include derivative instruments, available for sale and trading securities, loans held for sale and long-term debt. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. Examples of these non-recurring uses of fair value include certain loans held for sale accounted for on a lower of cost or fair value, mortgage 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 applied 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 or most advantageous 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.
Other Real Estate Owned	Other Real Estate Owned: Other real estate owned (“OREO”) consists 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 loan 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.
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. 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 recorded at fair value.
Intangible Assets	Intangible Assets: Mergers and acquisitions are accounted for using the acquisition method of accounting, which requires that acquired assets and liabilities are recorded at their fair values. This often involves estimates based on third party valuations or internal valuations based on discounted cash flow analyses or other valuation techniques, all of which are inherently subjective. The amortization of identified intangible assets is based upon the estimated economic benefits to be received, which is also subjective.
	Goodwill resulting from business combinations is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected October 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the Company’s balance sheet.
	The core deposit intangibles are intangible assets arising from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over a seven-year period on a straight line basis. The Company periodically evaluates whether events and circumstances have occurred that may affect the estimated useful lives or the recoverability of the remaining balance of the intangible assets.
Bank owned life insurance (BOLI)	Bank owned life insurance (BOLI): The Company, through its subsidiary bank, has purchased life insurance policies on certain key executives. Bank owned life insurance 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.
Revenue Recognition	Revenue Recognition: Revenue is recognized when the earnings process is complete and collectibility is assured. Brokerage fees and commissions are recognized on a trade date basis. Asset management fees, measured by assets at a particular date, are accrued as earned. Commission expenses are recorded when the related revenue is recognized.
Allowance for Loan Losses and Reserve for Unfunded Lending Commitments	Allowance for Loan Losses and Reserve for Unfunded Lending Commitments: The Company has developed policies and procedures for assessing the adequacy of the allowance for loan losses and reserve for unfunded lending commitments that reflect the evaluation of credit risk after careful consideration of all available information. Where appropriate this assessment includes monitoring qualitative and quantitative trends including changes in levels of past due, criticized and nonperforming loans. In developing this assessment, the Company must necessarily rely on estimates and exercise judgment regarding matters where the ultimate outcome is unknown such as economic factors, developments affecting companies in specific industries and issues with respect to single borrowers. Depending on changes in circumstances, future assessments of credit risk may yield materially different results, which may result in an increase or a decrease in the allowance for loan losses.
	The allowance for loan losses and reserve for unfunded lending commitments is maintained at a level the Company believes is adequate to absorb probable losses incurred in the loan portfolio and unfunded lending commitments as of the date of the consolidated financial statements. The Company employs a variety of modeling and estimation tools in developing the appropriate allowance for loan losses and reserve for unfunded lending commitments. The allowance for loan losses and reserve for unfunded lending commitments consists of formula-based components for both commercial and consumer loans, allowance for impaired commercial loans and allowance related to additional factors that are believed indicative of current trends and business cycle issues.
	If necessary, a specific allowance is established for individually evaluated impaired loans. The specific allowance established for these loans is based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated market value, or the estimated fair value of the underlying collateral depending on the most likely source of repayment. General allowances are established for loans grouped into pools based on similar characteristics. In this process, general allowance factors are based on an analysis of historical charge-off experience, portfolio trends, regional and national economic conditions, and expected loss given default derived from the Company’s internal risk rating process.
	The Company monitors qualitative and quantitative trends in the loan portfolio, including changes in the levels of past due, criticized and nonperforming loans. The distribution of the allowance for loan losses and reserve for unfunded lending commitments between the various components does not diminish the fact that the entire allowance for loan losses and reserve for unfunded lending commitments is available to absorb credit losses in the loan portfolio. The principal focus is, therefore, on the adequacy of the total allowance for loan losses and reserve for unfunded lending commitments.
	In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s bank subsidiary’s allowance for loan losses and reserve for unfunded lending commitments. These agencies may require such subsidiaries to recognize changes to the allowance for loan losses and reserve for unfunded lending commitments based on their judgments about information available to them at the time of their examination.
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. See Note L, Income Taxes for related disclosures.
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.
Stock-Based Compensation	Stock-Based Compensation: The stock option plans are accounted for under ASC Topic 718 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 five years. (See Note J)
	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 five 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.
