Basis of Presentation	'
	NOTE A — BASIS OF PRESENTATION
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U. S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U. S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine-month period ended September 30, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2012.
	Use of Estimates
	The preparation of these condensed consolidated financial statements required the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from those estimates.
	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, fair value of other real estate owned, and the valuation of deferred tax assets. Actual results could differ from those estimates.

Recently Issued Accounting Standards	'
	NOTE B — RECENTLY ISSUED ACCOUNTING STANDARDS
	In February 2013, the FASB issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. The ASU requires the measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement with its co-obligors as well as any additional amount that the entity expects to pay on behalf of its co-obligors. The new standard is effective retrospectively for fiscal years and interim periods within those years, beginning after December 15, 2013, and early adoption is permitted. We are currently evaluating the implications of ASU 2013-04. The Company does not expect it will have a material impact on the Company’s consolidated financial statements.
	On March 4, 2013, the FASB issued ASU 2013-05, Foreign Currency Matters: Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, a consensus of the FASB Emerging Issues Task Force. The ASU requires that the entire amount of a cumulative translation adjustment (CTA) related to an entity’s investment in a foreign entity should be released when there has been a:

		•	sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity,

		•	loss of a controlling financial interest in an investment in a foreign entity (i.e., the foreign entity is deconsolidated), or

		•	step acquisition for a foreign entity (i.e., when an entity has changed from applying the equity method for an investment in a foreign entity to consolidating the foreign entity).
	The ASU does not change the requirement to release a pro rata portion of the CTA of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity. The ASU is effective for fiscal years (and interim periods within those fiscal years) beginning on or after December 15, 2013. The ASU should be applied prospectively from the beginning of the fiscal year of adoption. We are currently evaluating the effect of adopting this standard effective January 1, 2014, but we do not anticipate that our adoption will have a material impact on our consolidated financial condition or results of operations.

Their fair value at September 30, 2013 is $71.5 million and is attributable to a combination of factors, including relative changes in interest rates since the time of purchase and decreased liquidity for investment securities in general. The collateral underlying these mortgage investments are 30- and 15-year fixed and 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 September 30, 2013, the Company also had $13.8 million of unrealized losses on mortgage backed securities of government sponsored entities having a fair value of $410.6 million that were attributable to a combination of factors, including relative changes in interest rates since the time of purchase and higher prepayments compressing prices as a result of the Federal Reserve’s actions to maintain low interest rates. 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.
As of September 30, 2013, management does not intend to sell securities that are in significant 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 September 30, 2013.
Included in other assets is $11.3 million of Federal Home Loan Bank and Federal Reserve Bank stock stated at par value. At September 30, 2013, the Company has not identified events or changes in circumstances which may have a significant adverse effect on the fair value of the $11.3 million of cost method investment securities.

	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 September 30, 2013 and December 31, 2012:

Text Block [Abstract]	'
Impaired Loans and Valuation Allowance for Loan Losses	'
	NOTE F — IMPAIRED LOANS AND VALUATION ALLOWANCE FOR LOAN LOSSES

	During the first, second and third quarters of 2013, newly identified troubled debt restructurings (“TDRs”) totaled $4.4 million, $4.1 million, and $1.7 million, respectively, summing to $10.2 million, of which $3.4 million were accruing commercial real estate loans, $1.0 million were accruing residential real estate mortgages, and $0.1 million were accruing consumer loans. Loans modified, but where full collection under the modified terms is doubtful are classified as nonaccrual loans from the date of modification and are therefore excluded from the tables below.

	The Company’s TDR concessions granted generally do not include forgiveness of principal balances. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements.

	When a loan is modified as a TDR, there is not a direct, material impact on the loans within the Consolidated Balance Sheet, as principal balances are generally not forgiven. Most loans prior to modification were classified as an impaired loan and the allowance for loan losses is determined in accordance with Company’s policy.



	The following table presents loans that were modified within the nine months ending September 30, 2013:

	Accruing loans that were restructured within the twelve months preceding September 30, 2013 and defaulted during the nine months ended September 30, 2013 are presented in the table below. The Company considers a loan to have defaulted when it becomes 60 days or more delinquent under the modified terms, has been transferred to nonaccrual status, or has been transferred to other real estate owned. A defaulted TDR is generally placed on nonaccrual and specific allowance for loan loss is assigned in accordance with the Company’s policy.

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 September 30, 2013 and December 31, 2012, accruing TDRs totaled $25.5 million and $41.9 million, respectively.

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 nine months ended September 30, 2013 and 2012, the Company recorded $910,000 and $2,400,000, 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 $1,069,000 and $759,000, respectively, was included in interest income for the nine months ended September 30, 2013 and 2012, and represents the change in present value attributable to the passage of time.

	The Company has net deferred tax assets (“DTA”) of $65.9 million at September 30, 2013, and is included as a component of other assets. Although not assured, the Company believes that the realization of the recognized current carrying value of the DTA is more likely than not based on expectations as to future taxable income and available tax planning strategies, as defined in ASC 740 “Income Taxes”, which could be implemented if necessary to prevent a carryforward from expiring. The Company’s credit losses have moderated, the Company no longer has a three year cumulative loss and the Company’s taxable earnings should result in realization of additional future tax benefits from net operating loss carryforwards. The net operating loss carryforwards expire in various amounts beginning in 2029 and run through 2032. For the three months ended September 30, 2013 the Company recorded the benefit from the reversal of approximately $44.8 million of deferred tax valuation allowance previously recorded during years 2007-10.

Fair Value	'
	NOTE J — 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 September 30, 2013 and 2012 included:

	-1	See Note F. 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 fair value 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 September 30, 2013 the range of capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 9 percent. 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 D.

	When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of other real estate owned (“OREO”) is classified as a level 2 input. When the fair value of OREO is based on appraisals which require significant adjustments to market-based valuation inputs or apply an income approach based on unobservable cash flows, OREO is classified as Level 3 inputs.

	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 quarterly valuation process.

	During the nine months ended September 30, 2013, 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 $2.2 million for the first nine months of 2013, consisting of loans that became impaired during 2013. Transfers out consisted of charge offs of $1.2 million, foreclosures migrating to OREO of $1.3 million, and other reductions (primarily principal payments) totaling $3.4 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 the first nine months of 2013, transfers in totaled $1.3 million. Transfers out totaled $5.2 million, consisting of valuation write-downs of $0.5 million and sales of $4.7 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 September 30, 2013 and 2012 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 September 30, 2013 and 2012:

Securities: U.S. Treasury securities are reported at fair value utilizing Level 1 inputs. Other securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. 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, nearly all 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. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from 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 and estimates of the Company’s current incremental borrowing rate for similar instruments.

	Use of Estimates
	The preparation of these condensed consolidated financial statements required the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from those estimates.
	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, fair value of other real estate owned, and the valuation of deferred tax assets. Actual results could differ from those estimates.
Fair Value Policy	'
	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.
Recently Issued Accounting Standards	'
	In February 2013, the FASB issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. The ASU requires the measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement with its co-obligors as well as any additional amount that the entity expects to pay on behalf of its co-obligors. The new standard is effective retrospectively for fiscal years and interim periods within those years, beginning after December 15, 2013, and early adoption is permitted. We are currently evaluating the implications of ASU 2013-04. The Company does not expect it will have a material impact on the Company’s consolidated financial statements.
	On March 4, 2013, the FASB issued ASU 2013-05, Foreign Currency Matters: Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, a consensus of the FASB Emerging Issues Task Force. The ASU requires that the entire amount of a cumulative translation adjustment (CTA) related to an entity’s investment in a foreign entity should be released when there has been a:

		•	sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity,

		•	loss of a controlling financial interest in an investment in a foreign entity (i.e., the foreign entity is deconsolidated), or

		•	step acquisition for a foreign entity (i.e., when an entity has changed from applying the equity method for an investment in a foreign entity to consolidating the foreign entity).
	The ASU does not change the requirement to release a pro rata portion of the CTA of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity. The ASU is effective for fiscal years (and interim periods within those fiscal years) beginning on or after December 15, 2013. The ASU should be applied prospectively from the beginning of the fiscal year of adoption. We are currently evaluating the effect of adopting this standard effective January 1, 2014, but we do not anticipate that our adoption will have a material impact on our consolidated financial condition or results of operations.
Income Taxes	'
	The Company has net deferred tax assets (“DTA”) of $65.9 million at September 30, 2013, and is included as a component of other assets. Although not assured, the Company believes that the realization of the recognized current carrying value of the DTA is more likely than not based on expectations as to future taxable income and available tax planning strategies, as defined in ASC 740 “Income Taxes”, which could be implemented if necessary to prevent a carryforward from expiring.
