	In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). The new ASU implements a common revenue standard that clarifies the principles for recognizing revenue from contracts with customers. The new accounting guidance, which does not apply to financial instruments, is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and is not expected to have a significant impact on the Company's financial statements.

	At June 30, 2014, the Company held 23 investment securities that were in an unrealized loss position. Market changes in interest rates and credit spreads may result in temporary unrealized losses as market prices of securities fluctuate. The Company reviews its investment portfolio on a quarterly basis for indications of other than temporary impairment ("OTTI"). The severity and duration of impairment and the likelihood of potential recovery of impairment is considered along with the intent and ability to hold any impaired security to maturity or recovery of carrying value. More specifically, when analyzing the nonagency portfolio, the Company uses cash flow models that estimate cash flows on security-specific collateral and the transaction structure. Future expected credit losses are determined by using various assumptions, the most significant of which include current default rates, prepayment rates and loss severities. Credit information is available and modeled at the loan level underlying each security during the OTTI analysis; the Company also considers information such as loan to collateral values, FICO scores and geographic considerations, such as home price appreciation or depreciation. These inputs are updated quarterly or as changes occur to ensure that the most current credit and other assumptions are utilized in the analysis. If, based on the analysis, the Company does not expect to recover the entire amortized cost basis of the security, the expected cash flows are discounted at the security's initial effective interest rate to arrive at a present value amount. OTTI credit losses reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of these securities. At June 30, 2014, there was no intent to sell any of the securities held as available-for-sale, and it is more likely than not that the Company will not be required to sell these securities. Furthermore, the present value of cash flows expected to be collected exceeded the Company's amortized cost basis of the investment securities. Therefore, these securities are not deemed to be other than temporarily impaired.
	Sales and calls of securities available-for-sale are summarized in the following table (dollars in thousands):
		Three Months Ended				Six Months Ended
		30-Jun				30-Jun
		2014		2013		2014		2013
	Proceeds from sales and calls	$	3,560	$	—	$	12,696	$	3,422
	Gross gains on securities available-for-sale	$	12	$	—	$	23	$	364
	Gross losses on securities available-for-sale	—		—		—		—
	Net realized gains on sales and calls of securities available-for-sale	$	12	$	—	$	23	$	364
	The composition of investment securities reflects the strategy of management to maintain an appropriate level of liquidity while providing a relatively stable source of revenue. The securities portfolio may at times be used to mitigate interest rate risk associated with other areas of the balance sheet while also providing a means for the investment of available funds, providing liquidity and supplying investment securities that are required to be pledged as collateral against specific deposits and for other purposes. Investment securities with an aggregate fair value of $165.4 million and $132.0 million at June 30, 2014 and December 31, 2013, respectively, were pledged to secure public deposits.

	Loans Receivable
	Concurrently with each of the Bank's twelve failed bank acquisitions, the Bank entered into loss share agreements with the FDIC that cover certain of the acquired loans and other real estate owned. The Company refers to loans subject to loss share agreements with the FDIC as "covered loans" and loans that are not subject to loss share agreements with the FDIC as "noncovered loans."
	Noncovered loans are summarized as follows (dollars in thousands):
		June 30, 2014			December 31, 2013
	Construction, land & land development	$	271,525		$	251,043
	Other commercial real estate	616,418			550,474

	Consumer & other	43,994			50,120
	Total noncovered loans	1,230,304			1,123,475
	Allowance for loan losses	(17,885		)	(16,656		)
	Total noncovered loans, net	$	1,212,419		$	1,106,819
	The table above includes net deferred loan fees that totaled approximately $3.6 million and $2.6 million at June 30, 2014 and December 31, 2013, respectively.
	Covered loans, net of related discounts, are summarized as follows (dollars in thousands):
		June 30, 2014			December 31, 2013
	Construction, land & land development	$	23,851		$	35,383

	Balance, end of period	$	193,580		$	316,053		$	193,580		$	316,053
	Covered loans are reported at their recorded investment excluding the expected reimbursement from the FDIC. Covered loans are initially recorded at fair value at the acquisition date. Prospective losses incurred on covered loans are eligible for partial reimbursement by the FDIC under loss share agreements. Subsequent decreases in the amount of cash expected to be collected from the borrower result in a provision for loan losses, an increase in the allowance for loan losses and a proportional adjustment to the FDIC receivable for the estimated amount to be reimbursed, discounted to present value. Subsequent increases in the amount of cash expected to be collected from the borrower result in the reversal of any previously-recorded provision for loan losses and related allowance for loan losses and a downward adjustment to the FDIC receivable, or a prospective increase in the accretable discount on the covered loans if no provision for loan losses had been recorded. The accretable discount is accreted into interest income over the estimated life of the related loan on a level yield basis.
	Changes in the value of the accretable discount allocated by acquired bank are presented in the following tables as of the dates indicated (dollars in thousands):

For each period indicated, a significant portion of the Company's covered loans were past due, including many that were 90 days or more past due; however, such delinquencies were included in the Company's performance expectations in determining the fair values of covered loans at each acquisition and at subsequent valuation dates. All covered loan cash flows and the timing of such cash flows continue to be estimable and probable of collection and thus accretion income continues to be recognized on these covered assets. As such, the referenced covered loans are not considered nonperforming assets.
Approved credit losses are expected to be reimbursed for covered loans under the FDIC loss share agreements at either 80 or 95 percent, in accordance with the applicable corresponding loss share agreement. The Company uses a symmetrical accounting approach in recording the loan carrying values and the FDIC receivable on covered loans. Subsequent decreases in the amount of cash expected to be collected on covered loans results in a provision for loan losses and an increase in the FDIC receivable, through an adjustment to income, which are taken immediately. Subsequent increases in the amount of cash expected to be collected on covered loans results in the reversal of any previously-recorded provision for loan losses and related allowance for loan losses and a downward adjustment to the FDIC receivable, or a prospective increase in the accretable discount on the covered loans if no provision for loan losses had been recorded.

Asset Quality Grades:
The Company assigns loans into risk categories based on relevant information about the ability of borrowers to pay their debts, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. A loan's risk grade is assigned at inception based upon the strength of the repayment sources and reassessed periodically throughout the year. Loans over certain dollar thresholds identified as having weaknesses are subject to more frequent review. In addition, the Company's internal loan review department provides an ongoing, comprehensive, and independent assessment of credit risk within the Company.
Loans are graded on a scale of 1 to 8. A description of the general characteristics of grades 5 and above is as follows:
Watch (Grade 5)—Loans graded Watch are pass credits that have not met performance expectations or that have higher inherent risk characteristics warranting continued supervision and attention.
OAEM (Grade 6)—Loans graded OAEM (other assets especially mentioned) have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the Company's credit position at some future date. OAEM loans are not adversely classified and do not expose the institution to sufficient risk to warrant adverse classification.
Substandard (Grade 7)—Loans classified as substandard are inadequately protected by the current sound worth and payment capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
Doubtful (Grade 8)—Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Classifications on covered loans are based upon the borrower's ability to pay the current unpaid principal balance without regard to loss share coverage or the net carrying value of the loan on the Company's balance sheet. Because the values shown in the table below are based on each loan's estimated cash flows, any expected losses should be covered by a combination of the specific reserves established in the allowance for loan losses on covered loans plus the discounts to the unpaid principal balances reflected in the recorded investment of each loan.

Total noncovered troubled debt restructurings (TDRs) were $875,000 at June 30, 2014 and $869,000 at December 31, 2013. The Company had no unfunded commitment obligations to lend to customers that underwent troubled debt restructuring at June 30, 2014 and December 31, 2013. Acquired and covered impaired loans modified post-acquisition are not removed from their accounting pools and accounted for as TDRs, even if those loans would otherwise be deemed TDRs.
There was no noncovered allowance for loan losses for identified TDRs during the three and six months ended June 30, 2014 and June 30, 2013. During the three and six months ended June 30, 2014 and 2013, there were no noncovered loans modified under the terms of a TDR. During the three and six months ended June 30, 2014 and 2013, there were no noncovered TDRs that subsequently defaulted within twelve months of their modification dates.

	Derivative Instruments and Hedging Activities
	Risk Management Objective of Using Derivatives
	The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of certain balance sheet assets and liabilities. In the normal course of business, the Company also uses derivative financial instruments to add stability to interest income or expense and to manage its exposure to movements in interest rates. The Company does not use derivatives for trading or speculative purposes and only enters into transactions that have a qualifying hedging relationship. The Company's hedging strategies involving interest rate derivatives are classified as either Fair Value Hedges or Cash Flow Hedges, depending on the rate characteristic of the hedged item.
	Fair Value Hedge: As a result of interest rate fluctuations, fixed-rate assets and liabilities will appreciate or depreciate in fair value. When effectively hedged, this appreciation or depreciation will generally be offset by fluctuations in the fair value of the derivative instruments that are linked to the hedged assets and liabilities. This strategy is referred to as a fair value hedge.
	Cash Flow Hedge: Cash flows related to floating-rate assets and liabilities will fluctuate with changes in an underlying rate index. When effectively hedged, the increases or decreases in cash flows related to the floating rate asset or liability will generally be offset by changes in cash flows of the derivative instrument designated as a hedge. This strategy is referred to as a cash flow hedge.
	The table below presents the fair value of the Company's derivative financial instruments (dollars in thousands):
		Derivatives designated as hedging instruments

	The Company uses interest rate swaps and caps as part of its interest rate risk management strategy. Interest rate swaps, designated as fair value hedges, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments over the life of the agreements without the exchange of the underlying notional amount. The gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. As of June 30, 2014, the Company had 83 interest rate swaps with an aggregate notional amount of $161.9 million, all but one of which, were designated as fair value hedges associated with the Company's fixed rate loan program.
	Interest rate caps, designated as cash flow hedges, involve the payment of a premium to a counterparty based on the notional size and cap strike rate. The Company's current cash flow hedges are for the purpose of capping the interest rate paid on variable rate liabilities which protect the Company in a rising rate environment. The caps were purchased during the first quarter of 2013 to hedge the variable cash outflows associated with these liabilities; they originally had a five-year life and notional value of $200.0 million.
	The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (AOCI) and is subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of derivatives that qualify as cash flow hedges is recognized directly in earnings. No hedge ineffectiveness was recognized on the Company's cash flow hedge during the periods ended June 30, 2014 and 2013.
	Amounts reported in AOCI related to derivatives are reclassified to interest expense as the interest rate cap premium is amortized over the life of the cap. During the next twelve months, $382,000 is expected to be reclassified as a decrease to net interest income.
	During the three and six months ended June 30, 2014, the Company recognized net losses of $175,000 and $418,000, respectively, and during the three and six months ended June 30, 2013, the Company recognized net gains of $455,000 and $546,000, respectively, related to hedge ineffectiveness of the fair value hedging relationships. The Company also recognized a net reduction in interest income of $508,000 and $947,000, respectively, for the three and six months ended June 30, 2014 and a net reduction in interest income of $360,000 and $632,000, respectively, for the three and six months ended June 30, 2013 related to the Company's fair value hedges, which include net settlements on the derivatives and any amortization adjustment of the basis in the hedged items. Terminations of derivatives and related hedged items for interest rate swap agreements prior to their original maturity date resulted in the recognition of net gains of $21,000 and $23,000 in noninterest income for the three and six months ended June 30, 2014, respectively, and recognition of net (losses) gains of $(18,000) and $2,000 in noninterest income for the three and six months ended June 30, 2013, respectively, related to the unamortized basis in the hedged items.

	Credit-Risk-Related Contingent Features
	The Company manages credit exposure on derivatives transactions by entering into a bilateral credit support agreement with each counterparty. The credit support agreements require collateralization of exposures beyond specified minimum threshold amounts. The details of these agreements, including the minimum thresholds, vary by counterparty. As of June 30, 2014, the Company has received $4.2 million in cash collateral under these agreements.
	The Company’s agreements with its derivative counterparties contain a provision where if either party defaults on any of its indebtedness, then it could also be declared in default on its derivative obligations. The agreements with derivative counterparties also include provisions that if not met, could result in the Company being declared in default. If the Company were to be declared in default, the counterparty could terminate the derivative positions and the Company and the counterparty would be required to settle their obligations under the agreements. As of June 30, 2014, the termination value of derivatives in a net liability position under these agreements was $237,000. Although the Company did not breach any provisions at June 30, 2014, had a breach occurred, the Company could have been required to settle obligations under the agreements at their termination value.

	Share-Based Compensation
	The Company maintains an incentive compensation plan that includes share-based compensation. The State Bank Financial Corporation 2011 Omnibus Equity Compensation Plan (the "Plan") was approved by the Company's shareholders in 2011 and authorizes up to 3,160,000 shares of common stock for issuance in accordance with the Plan terms. Descriptions of these grants and the Plan, including the terms of awards and the number of shares authorized for issuance, were included in Note 16 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.
	The Company issued 7,000 shares of restricted stock under the Plan to its independent directors during the six months ended June 30, 2014. There were 12,000 shares of restricted stock that vested and 4,000 shares of restricted stock that were forfeited during the six months ended June 30, 2014.
	The Company recognized compensation expense related to equity awards of $353,000 and $828,000 for three and six months ended June 30, 2014, compared to $324,000 and $636,000 for the same periods in 2013, respectively. Unearned share-based compensation associated with these equity awards totaled $4.2 million at June 30, 2014.

Under the terms of the Capital Maintenance Agreement, the Bank is required to maintain a leverage ratio of at least 10% and a total risk-based capital ratio of at least 12%. During the term of the agreement, if at any time the Bank's leverage ratio falls below 10%, or its risk-based capital ratio falls below 12%, the Company is required to immediately cause sufficient actions to be taken to restore the Bank's leverage and risk-based capital ratios to 10% and 12%, respectively. The Capital Maintenance Agreement expires on July 26, 2016. The Company and the Bank were in compliance with the Capital Maintenance Agreement at June 30, 2014.
	Regulatory Restrictions on Dividends
	Regulatory policy statements provide that generally bank holding companies should pay dividends only out of current operating earnings and that the level of dividends must be consistent with current and expected capital requirements. Dividends received from the Bank have been the primary source of funds available for the declaration and payment of dividends to the Company's common shareholders.
	Federal and state banking laws and regulations restrict the amount of dividends the Bank may distribute without prior regulatory approval. At June 30, 2014, the Bank had the capacity to pay $6.9 million in dividends to the Company without prior regulatory approval.
	At June 30, 2014, the Company had $54.5 million in cash and due from bank accounts, which can be used for additional capital as needed by the Bank, payment of holding company expenses, payment of dividends to shareholders, or for other corporate purposes. The Company declared a cash dividend of $.04 per common share to the Company's shareholders for the quarter ended June 30, 2014 and has declared a cash dividend of $.03 per common share every quarter from the quarter ended September 30, 2012 through the quarter ended March 31, 2014.

	Commitments and Contingent Liabilities
	In order to meet the financing needs of its customers, the Company maintains financial instruments with off-balance-sheet risk in the normal course of business. These financial instruments include commitments to extend credit and standby letters of credit; and involve, to varying degrees, elements of credit, interest rate and/or liquidity risk. Such financial instruments are recorded when they are funded and the related fees are generally recognized when collected.
	Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed maturity dates or other termination clauses with required fee payments. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The amount of collateral required, if deemed necessary upon extension of credit, is determined on a case by case basis by management through credit evaluation of the customer.
	Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those guarantees are issued primarily to support public and private borrowing arrangements. In order to minimize its exposure, the Company's credit policies govern the issuance of standby letters of credit.
	The Company's exposure to credit loss is represented by the contractual amount of those instruments. We use the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments.
	A summary of the Company's commitments is as follows (dollars in thousands):
		June 30, 2014		December 31, 2013
	Commitments to extend credit:
	Fixed	$	15,043	$	9,848
	Variable	331,317		290,079
	Standby letters of credit:
	Fixed	488		379
	Variable	772		1,274
	Total	$	347,620	$	301,580
	The fixed rate loan commitments have maturities ranging from one month to nine years. Management takes appropriate actions to mitigate interest rate risk associated with these fixed rate commitments through various measures including, but not limited to, the use of derivative financial instruments.
	In the normal course of business, the Company is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material effect on the Company's financial statements.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Fair Value
	Fair value measurements are determined based on the assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, the Financial Accounting Standards Board's Accounting Standards Codification Topic 820 ("ASC 820") Fair Value Measurements and Disclosures establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs classified within Level 3 of the hierarchy).
	Fair Value Hierarchy
	Level 1
	Valuation is based on inputs that are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
	Level 2
	Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as interest rates, yield curves observable at commonly quoted intervals, and other market-corroborated inputs.
	Level 3
	Valuation inputs are unobservable inputs for the asset or liability, which are used to measure fair value to the extent that observable inputs are not available. The inputs reflect the Company's own assumptions about the assumptions that market participants would use in pricing the asset or liability.
	In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The Company evaluates fair value measurement inputs on an ongoing basis in order to determine if there is a change of sufficient significance to warrant a transfer between levels. 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 valuation process. For the six months ended June 30, 2014 and the year ended December 31, 2013, there were no transfers between levels.
	Financial Assets and Financial Liabilities Measured on a Recurring Basis
	The following methods and assumptions are used by the Company in estimating the fair value of its financial assets and financial liabilities on a recurring basis:
	Investment Securities Available-for-Sale
	At June 30, 2014, the Company's investment portfolio primarily consisted of U.S. government agency mortgage-backed securities, nonagency mortgage-backed securities, U.S. government securities, municipal securities, asset-backed securities and equity securities. The fair values for U.S. Treasury and equity securities are determined by obtaining quoted prices on nationally recognized securities exchanges utilizing Level 1 inputs. Other securities classified as available-for-sale are reported at fair value utilizing Level 2 inputs. The fair value of other securities classified as available-for-sale are determined using widely accepted valuation techniques including matrix pricing and broker-quote-based applications. Inputs 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 relevant items. 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. From time to time, the Company validates the appropriateness of the valuations provided by the independent pricing service to prices obtained from an additional third party or prices derived using internal models.
	Derivative Instruments and Hedging Activities
	The Company uses interest-rate swaps to provide longer-term fixed rate funding to its customers and interest-rate caps to mitigate the interest rate risk on its variable rate liabilities. The majority of these derivatives are traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract. Therefore, these derivative contracts are classified as Level 2. The Company utilizes an independent third party valuation company to validate the dealer prices. In cases where significant credit valuation adjustments are incorporated into the estimation of fair value, reported amounts are considered to have been derived utilizing Level 3 inputs.
	The Company evaluates the credit risk of its counterparties as well as that of the Company. The Company has considered factors such as the likelihood of default by the Company and its counterparties, its net exposures, and remaining contractual life, among other things, in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting arrangements, as well as considering the amount of collateral securing the position. The Company reviews its counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken to adjust the exposure. The Company also utilizes this approach to estimate its own credit risk on derivative liability positions. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position.

	Financial Assets Measured on a Nonrecurring Basis
	The following methods and assumptions are used by the Company in estimating the fair value of its financial assets on a nonrecurring basis:
	Impaired Noncovered Loans
	Noncovered loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The fair values of impaired noncovered loans are measured on a nonrecurring basis and are based on the underlying collateral value of each loan if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs that are based on observable market data such as an appraisal. Updated appraisals are obtained on at least an annual basis. Level 3 inputs are based on the Company's customized discounting criteria when management determines the fair value of the collateral is further impaired.
	Mortgage Loans Held for Sale
	Mortgage loans held for sale are recorded at the lower of cost or fair value. The fair values of mortgage loans held for sale are measured on a nonrecurring basis. Estimated fair value is determined using Level 2 inputs based on observable data such as the existing forward commitment terms or the current market value of similar loans.
	The following table presents the fair value measurements of financial assets measured at fair value on a nonrecurring basis as of June 30, 2014 and December 31, 2013, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Noncovered impaired loans that are measured for impairment using the fair value of collateral for collateral dependent loans had principal balances of $1.9 million and $2.3 million with respective valuation allowances of $385,000 and $303,000 at June 30, 2014 and December 31, 2013, respectively.
Nonfinancial Assets Measured on a Nonrecurring Basis
The following methods and assumptions are used by the Company in estimating the fair value of its nonfinancial assets on a nonrecurring basis:
Other Real Estate Owned
The fair value of other real estate owned is determined when the asset is transferred to foreclosed assets. Fair value is based on appraised values of the collateral. When the value is based on observable market prices such as an appraisal, the asset is recorded in Level 2 hierarchy. When an appraised value is not available or management determines the fair value of the collateral is further impaired, the asset is recorded as a nonrecurring Level 3 hierarchy. Management requires a new appraisal at the time of foreclosure or repossession of the underlying collateral. Updated appraisals are obtained on at least an annual basis on all other real estate owned.
The following table presents the fair value measurements of nonfinancial assets measured at fair value on a nonrecurring basis for the periods indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Other real estate owned (OREO) includes real property that has been acquired in satisfaction of loans receivable, noncovered and covered, and bank premises formerly, but no longer, used for a specific business purpose. Property acquired in satisfaction of loans receivable, consisting of real estate acquired through foreclosure or a deed in lieu of foreclosure in satisfaction of a loan, is initially recorded at the lower of the principal investment in the loan or the fair value of the collateral less estimated costs to sell at the time of foreclosure. Management considers a number of factors in estimating fair value including appraised value, estimated selling prices and current market conditions. Any excess of the loan balance over the fair value less estimated costs to sell is treated as a charge against the allowance for loan losses at the time of foreclosure. For acquired OREO, the loan is transferred into OREO at its fair value not to exceed the carrying value of the loan at foreclosure. Management periodically reviews the carrying value of OREO for impairment and adjusts the values as appropriate through noninterest expense. Bank premises are transferred at the lower of carrying value or fair value, less estimated selling costs.
The following table is a reconciliation of the fair value measurement of other real estate owned disclosed in accordance with ASC Topic 820, Fair Value Measurements and Disclosures, to the amount recorded on the consolidated statement of financial condition (dollars in thousands):

Fair Value of Financial Assets and Financial Liabilities
The following table includes the estimated fair value of the Company's financial assets and financial liabilities (dollars in thousands). The methodologies for estimating the fair value of financial assets and financial liabilities measured on a recurring and nonrecurring basis are discussed above. The methodologies for estimating the fair value for other financial assets and financial liabilities are discussed below. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies; however, considerable judgment is required to interpret market data in order to develop the estimates of fair value. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation techniques may have a material effect on the estimated fair value amounts at June 30, 2014 and December 31, 2013.

Accrued interest payable	Level 2		743				743				865				865
Cash and Cash Equivalents
The carrying amount approximates fair value because of the short maturity of these instruments.
Noncovered Loans
Fair values are estimated for portfolios of noncovered loans with similar financial characteristics. Loans are segregated by type. The fair value of performing noncovered loans is calculated by discounting scheduled cash flows through the estimated maturities using estimated market discount rates that reflect observable market information incorporating the credit, liquidity, yield, and other risks inherent in the loan. The estimate of maturity is based on the Company's historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of the current economic and lending conditions.
Covered Loans
Covered loans are recorded at fair value at the date of acquisition exclusive of expected cash flow reimbursements from the FDIC. The fair values of loans with evidence of credit deterioration are recorded net of a nonaccretable discount and an accretable discount. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases to the expected cash flows result in a reversal of the provision for loan losses to the extent of prior changes or a reclassification of the difference from the nonaccretable to accretable discount with a positive impact on the accretable discount.
FDIC Receivable for Loss Share Agreements
The FDIC receivable is recorded at fair value at the acquisition date. The FDIC receivable is recognized at the same time as the covered loans, and measured on the same basis, subject to collectibility or contractual limitations, and the FDIC receivable is impacted by changes in estimated cash flows associated with these loans.
Accrued Interest Receivable and Accrued Interest Payable
The carrying amounts are a reasonable estimate of fair values.
Federal Home Loan Bank stock
Federal Home Loan Bank stock, classified as a restricted equity security, is considered a Level 3 asset as little or no market activity exists for the security; therefore, the security's value is not market observable and is carried at original cost basis as cost approximates fair value.
Deposits
The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, interest-bearing deposits, and savings and money market deposits, is equal to the amount payable on demand. The fair value of time deposits is estimated by discounting the expected life. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities.
Securities Sold Under Agreements to Repurchase and Notes Payable
The fair value of securities sold under agreements to repurchase approximates the carrying amount because of the short maturity of these borrowings. The discount rate is estimated using the rates currently offered for borrowings of similar remaining maturities. Notes payable are variable rate subordinated debt for which performance is based on the underlying notes receivable and adjust accordingly.

	Proposed Acquisition of Atlanta Bancorporation, Inc.
	On April 25, 2014, the Company entered into a definitive agreement to acquire Atlanta Bancorporation, Inc. and its wholly-owned subsidiary, Bank of Atlanta. Upon the closing of the transaction, Atlanta Bancorporation, Inc. will merge into State Bank Financial Corporation, immediately followed by the merger of Bank of Atlanta into State Bank and Trust Company.
	At March 31, 2014, Bank of Atlanta had approximately $198.3 million of total assets, $123.1 million of loans and $161.2 million of deposits. Bank of Atlanta is headquartered in midtown Atlanta and operates one additional banking office in Duluth, Georgia.
	State Bank Financial Corporation has agreed to pay approximately $25.2 million in cash for all outstanding shares of Atlanta Bancorporation, Inc. The definitive agreement has been unanimously approved by the Boards of Directors of both companies and approved by Atlanta Bancorporation, Inc. shareholders. The acquisition is expected to close no later than the fourth quarter of 2014. Completion of the transaction is subject to certain closing conditions, including customary regulatory approvals.
	Proposed Acquisition of Georgia-Carolina Bancshares, Inc.
	On June 23, 2014, the Company entered into a definitive agreement to acquire Georgia-Carolina Bancshares, Inc. and its wholly-owned subsidiary, First Bank of Georgia, in a cash and stock transaction with a purchase price of approximately $82.4 million, or $22.35 per share of Georgia-Carolina Bancshares, Inc. stock. The transaction value at the time of the merger may change due to fluctuations in the price of the Company's common stock. Each share of Georgia-Carolina common stock will be converted into the right to receive $8.85 in cash and a number of shares of the Company's common stock equal to an exchange ratio, subject to the limitations that, if the aggregate value of the stock consideration is less than 40% of the aggregate merger consideration, the exchange ratio will be adjusted such that the aggregate stock consideration is at least 40% of the aggregate merger consideration. The exchange ratio will depend on the average closing price of the Company’s common stock during the twenty trading day period ending five business days before the closing of the transaction (the "Final State Bank Price"). If the Final State Bank Price is above $14.00 but below $17.00, the exchange ratio will be equal to $13.50 divided by the Final State Bank Price. If the Final State Bank Price is at or above $17.00, the exchange ratio will be 0.794. If the Final State Bank Price is at or below $14.00, the exchange ratio will be 0.964.
	At March 31, 2014, First Bank of Georgia had total assets of approximately $523.1 million, total loans, including mortgage loans held for sale, of approximately $316.5 million, total deposits of approximately $427.2 million and total shareholder's equity of approximately $59.5 million. First Bank of Georgia is headquartered in Augusta, Georgia and operates seven banking offices in the Augusta metropolitan statistical area. In addition, the bank operates mortgage origination offices in the Augusta and Savannah, Georgia markets.
	The definitive agreement has been unanimously approved by the Boards of Directors of both companies and is anticipated to close in the first quarter of 2015. Completion of the transaction is subject to certain closing conditions, including customary regulatory approvals and the approval by shareholders of Georgia-Carolina Bancshares, Inc.
