	Nature of Business and Summary of Significant Accounting Policies
	The consolidated financial statements of State Bank Financial Corporation and Subsidiary (the "Company") include the financial statements of State Bank Financial Corporation and its wholly-owned subsidiary, State Bank and Trust Company (the "Bank"). All intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications of prior year amounts have been made to conform with the current year presentations. These reclassifications had no impact on prior years' net income, as previously reported.
	State Bank and Trust Company was organized as a Georgia-state chartered bank, which opened October 4, 2005 in Pinehurst, Georgia. The Bank is primarily regulated by the FDIC and undergoes periodic examinations by this regulatory authority. On July 24, 2009, State Bank and Trust Company closed on investment agreements under which new investors infused $292.1 million, gross (before expenses), of additional capital into the Bank, which resulted in a successor entity. This significant recapitalization resulted in a change of control and a new basis of accounting was applied. At the annual shareholders' meeting held March 11, 2010, approval was granted through proxy vote for the formation of a bank holding company. The required regulatory approval was obtained in July 2010 and the holding company reorganization was completed July 23, 2010.
	The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America and to prevailing practices within the financial institutions industry. The following is a summary of the significant accounting policies that the Company follows in presenting its consolidated financial statements.
	(a) Nature of Business
	State Bank Financial Corporation is a bank holding company whose primary business is presently conducted through 19 branch offices of State Bank and Trust Company, its wholly-owned banking subsidiary. Through the Bank, the Company operates a full service banking business and offers a broad range of commercial and retail banking products to its customers, which range from Metro Atlanta to middle Georgia, with a significant focus on the resolution of assets acquired from the FDIC. The Company is subject to regulations of certain federal and state agencies and is periodically examined by those regulatory agencies.
	(b) Basis of Presentation
	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenue and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the estimates used for fair value acquisition accounting and the FDIC receivable for loss share agreements, and the assessment for other than temporary impairment of investment securities. In connection with the determination of the allowance for loan losses and the value of real estate owned, management obtains independent appraisals for significant properties. In connection with the assessment for other than temporary impairment of investment securities, management obtains fair value estimates by independent quotations, assesses current credit ratings and related trends, reviews relevant delinquency and default information, assesses expected cash flows and coverage ratios, assesses the relative strength of credit support from less senior tranches of the securities, reviews average credit score data of underlying mortgages, and assesses other current data. 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.
	A substantial portion of the Company's loans are secured by real estate located in its market area. Accordingly, the ultimate collectability of a substantial portion of the Company's loan portfolio is susceptible to changes in the real estate market conditions of this market area.
	As defined by authoritative guidance, segment disclosures require reporting information about a company's operating segments using a “management approach.” Reportable segments are identified as those revenue-producing components for which separate financial information is produced internally and which are subject to evaluation by the chief operating decision maker in deciding how to allocate resources to segments. The Company operates as one reportable segment.
	(c) Cash and Cash Equivalents
	Cash and cash equivalents, as presented in the consolidated financial statements, includes cash on hand, cash items in process of collection and interest-bearing deposits with other financial institutions with maturities less than 90 days.
	(d) Investments
	Management determines the appropriate classifications of investment securities at the time of purchase and reevaluates such designation as needed. At December 31, 2013 and 2012, the Company classified all of its investment securities as available-for-sale. Investments available-for-sale are reported at fair value, as determined by independent quotations. Purchase premiums and discounts on investment securities are amortized and accreted to interest income using the effective interest rate method over the remaining lives of the securities, taking into consideration assumed prepayment patterns. Realized gains and losses are derived using the specific identification method for determining the cost of securities sold and are recognized on the trade date.
	Unrealized holding losses, other than those determined to be other than temporary, and unrealized holding gains are excluded from net income and are reported, net of tax, in other comprehensive income and in accumulated other comprehensive income, a separate component of shareholders' equity. A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for that security. At December 31, 2013 and 2012, the Company did not have any securities with other than temporary impairment.
	Investment in stock of the Federal Home Loan Bank ("FHLB") is required of every federally insured financial institution which utilizes the FHLB's services. The investment in FHLB stock is included in "other assets" at its original cost basis, as cost approximates fair value since there is no readily determinable market value for such investments.
	(e) Noncovered Loans
	Loans, excluding loans covered by FDIC loss share agreements, that management has the intent and ability to hold for the foreseeable future, until maturity, or payoff are reported at their principal amounts outstanding, net of unearned income, deferred loan fees and origination costs, unamortized premiums or discounts on purchased loans, and the allowance for loan losses. Interest income is recognized using the simple interest method on the daily balance of their principal amount outstanding. Unearned income, primarily arising from deferred loan fees, net of certain origination costs is amortized over the lives of the underlying loans using the effective interest rate method.
	Past due status is based on the contractual terms of the loan agreement. Generally, the accrual of interest income is discontinued and loans are placed on nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal. Interest previously accrued but not collected is reversed against current period interest income when such loans are placed on nonaccrual status. Interest on nonaccrual loans when ultimately collected is recorded as a principal reduction. Nonaccrual loans are returned to accrual status when all principal and interest amounts contractually due are brought current. In addition, the future payments must be reasonably assured along with a period of at least six months of repayment performance by the borrower depending on the contractual payment terms. When it has been determined that a loan cannot be collected in whole or in part, then the uncollectible portion will be charged-off.
	The Company considers a loan 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. Additionally, loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings ("TDRs") and are included in impaired loans. The Company's policy requires that all impaired loans with contractual balances of $500,000 and greater be individually reviewed for impairment. Loans are reviewed for impairment based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or the loan's observable market price, or the fair value of the collateral less disposal costs, as applicable, if the loan is collateral dependent. The Company's policy requires that large pools of smaller balance homogeneous loans, such as consumer, residential and installment loans, be collectively evaluated for impairment by the Company. Impairment losses are included in the allowance for loan losses through a charge to the provision for loan losses. All loans considered impaired are placed on nonaccrual status in accordance with policy. The interest portion of cash receipts on impaired loans are recorded as income when received unless full recovery of principal is in doubt whereby cash received is recorded as a reduction to the Company's recorded investment in the loan.
	All impaired loans are reviewed, at minimum, on a quarterly basis. Reviews may be performed more frequently if material information is available before the next scheduled quarterly review. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. The discounts may include the following: length of time to market and sell the property, as well as expected maintenance costs, insurance and taxes and real estate commissions on sale.
	(f) Covered Loans
	Covered loans, defined as loans covered by loss share agreements with the FDIC, 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, if appropriate, an accretable discount. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan when there is reasonable expectation about the amount and timing of such cash flows. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is the nonaccretable discount, which is excluded in the carrying amount of acquired loans. Expected prepayments are treated consistently for cash flows expected to be collected and projections of contractual cash flows such that the nonaccretable discount is not affected. Similarly, the difference between actual prepayments and expected prepayments do not affect the nonaccretable discount. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior applicable loss provisions or a reclassification of the difference from nonaccretable to accretable with a positive impact on the accretable discount.
	The Company accounts for performing loans acquired in business combinations using the contractual cash flows method whereby premiums and discounts are recognized using the interest method. There is no allowance for loan losses established at the acquisition date for purchased performing loans. A provision for loan losses is recorded for any further deterioration in these loans subsequent to the acquisition.
	All loans acquired in failed bank transactions are considered to have evidence of credit deterioration as limited due diligence is afforded which does not allow a sufficient detailed review to classify the acquired loans into credit deterioration and performing categories.
	At the time of acquisition, loans with evidence of credit deterioration are either accounted for as specifically-reviewed or as part of a loan pool. Loan pools are created by grouping loans with similar risk characteristics, the intent being to create homogeneous pools. Loans are grouped into pools based on a combination of various factors including product type, cohort, risk classification and term. Loans remain in the assigned pool until they are resolved. Gains and losses are deferred and retained in the pools until the pool closes, which is either when all the loans are resolved or the pool’s recorded investment reaches zero.
	(g) Allowance for Loan Losses ("ALL")
	The ALL is a valuation allowance for probable incurred credit losses. The ALL is adjusted through provisions for loan losses charged or credited to operations. All or portions of loans, excluding covered loans, deemed to be uncollectible are charged against the ALL when management believes that collectability of all or some portion of outstanding principal is unlikely. Subsequent recoveries, if any, of loans previously charged-off are credited to the ALL. The ALL for noncovered loans is determined through consideration of such factors as changes in the nature and volume of the portfolio, overall portfolio quality, delinquency trends, adequacy of collateral, loan concentrations, specific problem loans, and economic conditions that may affect the borrowers' ability to pay.
	The ALL for noncovered loans consists of specific and general components. The specific component relates to loans that are individually identified as impaired. The general component covers nonimpaired loans and is based on historical loss experience adjusted for current environmental factors. This qualitative analysis requires judgment by management and is subject to continuous validation. The Company's noncovered loan portfolio has been originated over the past several years. The portfolio has been stringently underwritten and has experienced minimal losses. Beginning with fourth quarter 2011, the Company uses its own historical loss data in the allowance calculation.
	Management separately monitors the covered loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the acquisition date fair value. To the extent that the revised loss estimate exceeds the loss estimate established in the determination of the acquisition date fair values, such deterioration will result in additional provision for loan losses charged to expense.
	The ALL is maintained at a level management believes is adequate to absorb probable incurred losses. The Company has recorded all known and inherent losses that are both probable and reasonable to estimate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's allowance for loan losses. Such agencies may require the Company to adjust the allowance based on their judgment about information available to them at the time of their examination.
	The company assesses the adequacy of the ALL quarterly with respect to noncovered and covered loans. The assessment begins with a standard evaluation and analysis of each loan. All loans are consistently graded and monitored for changes in credit risk and possible deterioration in the borrower's ability to repay the contractual amounts due under the loan agreement.
	If a loan is impaired, under generally accepted accounting principles, the Company may measure the loss, or expected cash flow, either by:
	-1	the observable market price of the loan;
	-2	the present value of expected future cash flows discounted at the loan's effective interest rate; or
	-3	the fair value of the collateral if the loan is collateral dependent.
	Management evaluates the results of the ALL procedures performed, including the results of testing, and makes a conclusion regarding the appropriateness of the ALL in its entirety.
	Allowance for loan losses for noncovered loans:    The ALL for noncovered loans consists of two components:
	-1	a specific amount against identified credit exposures where it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreements; and
	-2	a general amount, based upon historical losses, that is then adjusted for qualitative factors representative of various economic indicators and risk characteristics of the loan portfolio.
	Management establishes the specific amount by examining impaired loans. The majority of the Company's impaired loans are collateral dependent; therefore, nearly all of the specific allowances are calculated based on the fair value of the collateral less disposal costs, if applicable.
	Management establishes the general amount by taking the remaining loan portfolio (excluding those impaired loans discussed above) with allocations based on historical losses. The calculation of the general amount is subjected to stress factors that are somewhat subjective. The stress testing attempts to correlate the historical loss rates with current economic factors and current risks in the portfolio. The stress factors consist of:
	-1	economic factors including changes in the local or national economy;
	-2	the depth of experience in lending staff;
	-3	any concentrations of credit (such as commercial real estate);
	-4	asset quality trends; and
	-5	seasoning of the loan portfolio.
	After assessing the applicable factors, the remaining amount is evaluated based on management's experience and the level of the noncovered ALL is compared with historical trends and peer information as a reasonableness test.
	Allowance for loan losses for covered loans: On the date of acquisition, management estimates the expected credit loss in the acquired loan portfolio and records the present value of the expected cash flows as the fair value of the acquired loans. Management determines which covered loans are placed in homogenous risk pools or reviewed specifically as part of the periodic cash flow re-estimation process. If a loan is placed in a pool, the overall performance of the pool will determine if any future ALL is required.
	The covered loan ALL analysis represents management's estimate of the potential impairment of the acquired loan portfolio over time. Typically, decreased cash flows result in impairment, while increased cash flows result in a full or partial reversal of previously recorded impairment and potentially the calculation of a higher effective yield. Higher actual cash flows than expected will result in a greater pay down of the covered loan, which decreases the recorded investment and therefore may cause an impairment reversal or higher effective yield. Lower actual cash flows than expected will result in a smaller pay down of the loan receivable and a higher recorded investment which may cause further impairment.
	If actual losses exceed the estimated losses, provision for loan losses is recorded on covered loans as an expense on the consolidated statement of income. The Company also records an amount that will be recovered, under the related FDIC loss share agreements, as a reduction of the provision for loan losses on the consolidated statement of income.
	Management reviews the assumptions used in the calculation of the updated expected cash flows, evaluates the impairment based on management's experience, and uses a third party to obtain peer information as part of its reasonableness test for the covered loan ALL.
	(h) Mortgage Loans Held for Sale
	Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Estimated fair value is determined on the basis of existing forward commitments or the current market value of similar loans. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.
	(i) Other Real Estate Owned
	Other real estate owned 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.
	Real estate acquired through foreclosure of noncovered loans, consisting of properties obtained through foreclosure proceedings or acceptance of a deed in lieu of foreclosure, is reported on an individual asset basis at fair value, less disposal costs. Fair value is determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources. When properties are acquired through foreclosure of noncovered loans, any excess of the loan balance at the time of foreclosure over the fair value of the real estate held as collateral is recognized and charged to the allowance for loan losses. Based upon management's evaluation of the real estate acquired through foreclosure, additional expense, when necessary, is recorded in current period earnings in an amount sufficient to reflect any estimated declines in fair value. Gains or losses recognized on the disposition of the properties are recorded in net costs of operations of other real estate in the consolidated statements of income.
	Other real estate acquired through foreclosure of covered loans under loss share agreements with the FDIC is reported exclusive of expected reimbursement cash flows from the FDIC. Subsequent adjustments to the estimated recoverable value of covered other real estate result in a reduction of covered other real estate, and a charge to other expense, and an increase in the FDIC receivable for the estimated amount to be reimbursed, with a corresponding net offsetting amount recorded to other expense.
	Banking premises are transferred at the lower of carrying value or fair value, less estimated selling costs and any write-down is expensed as incurred.
	Costs of improvements to real estate are capitalized, while costs associated with holding the real estate are charged to operations. Costs associating with holding covered other real estate are charged to operations, net of any expected reimbursements from the FDIC relating to covered external expenses.
	(j) Premises and Equipment
	Premises and equipment are stated at cost, less accumulated depreciation, which is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of the assets range from 10 to 25 years for buildings and improvements and 3 to 15 years for furniture, fixtures, and equipment. Costs of improvements are capitalized and depreciated, while operating expenses are charged to current earnings.
	(k) Goodwill and Other Intangibles
Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangibles deemed to have an indefinite life are not amortized but instead are subject to review for impairment annually, or more frequently if deemed necessary. Also in connection with business combinations, the Company records core deposit intangibles, representing the value of the acquired core deposit base, and other identifiable intangible assets. Core deposit intangibles and other identifiable intangible assets are amortized over their estimated useful lives ranging up to 5 years.
(l) FDIC Receivable for Loss Share Agreements
The FDIC receivable for loss share agreements is measured separately from the related covered assets and is not contractually embedded in the assets or transferable should the assets be sold. Fair value at acquisition was estimated using projected cash flows related to loss share agreements based on the expected reimbursements for losses using the applicable loss share percentages and the estimated true-up payment at the expiration of the loss sharing agreements, if applicable. These cash flows were discounted to reflect the estimated timing of the receipt of the loss share reimbursements from the FDIC. Any applicable true-up payments owed to the FDIC for transactions that include claw-back provisions are discounted to reflect the estimated timing of the payment and such amount is netted against the FDIC receivable. The FDIC receivable is reviewed and updated prospectively as loss estimates related to indemnified assets change and as reimbursements are received or are expected to be received from the FDIC. Improvements in the credit quality or cash flows of loans (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the FDIC receivable, with such decreases being amortized into income over the remaining life of the loan or life of the loss share agreement, whichever is shorter.
(m) Derivative Instruments and Hedging Activities
The Company enters into derivative financial instruments to manage interest rate risk, facilitate asset/liability management strategies and manage other exposures. These instruments may include interest rate swaps and interest rate caps and floors. All derivative financial instruments are recognized on the consolidated balance sheets as other assets or other liabilities, as applicable, at estimated fair value. The Company enters into master netting agreements with counterparties and/or requires collateral to cover exposures. In most cases, counterparties post at a zero threshold regardless of rating.
Interest rate swaps are agreements to exchange interest payments based upon notional amounts. Interest rate swaps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform. Option contracts involve rights to buy or sell financial instruments on a specified date or over a period at a specified price. These rights do not have to be exercised. Some option contracts such as interest rate caps, involve the exchange of cash based on changes in specified indices. Interest rate caps are contracts to hedge interest rate increases based on a notional amount. Interest rate caps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform.
Derivative financial instruments are designated, based on the exposure being hedged, as either fair value or cash flow hedges. Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Under the fair value hedging model, gains or losses attributable to the change in fair value of the derivative instrument, as well as the gains and losses attributable to the change in fair value of the hedged item, are recognized in other noninterest income in the period in which the change in fair value occurs. Hedge ineffectiveness is recognized as other noninterest income to the extent the changes in fair value of the derivative do not offset the changes in fair value of the hedged item. The corresponding adjustment to the hedged asset or liability is included in the basis of the hedged item, while the corresponding change in the fair value of the derivative instrument is recorded as an adjustment to other assets or other liabilities, as applicable. Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. For cash flow hedge relationships, the effective portion of the gain or loss related to the derivative instrument is recognized as a component of accumulated other comprehensive income (loss). The ineffective portion of the gain or loss related to the derivative instrument, if any, is recognized in earnings as other noninterest income during the period of change. Amounts recorded in accumulated other comprehensive income (loss) are recognized in earnings in the period or periods during which the hedged item impacts earnings.
The Company formally documents all hedging relationships between hedging instruments and the hedged items, as well as its risk management objective and strategy for entering into various hedge transactions. Methodologies related to hedge effectiveness and ineffectiveness are consistent between similar types of hedge transactions and typically include (i) statistical regression analysis of changes in the cash flows of the actual derivative and a perfectly effective hypothetical derivative, and (ii) statistical regression analysis of changes in the fair values of the actual derivative and the hedged item. The Company performs retrospective and prospective effectiveness testing using quantitative methods and does not assume perfect effectiveness through the matching of critical terms. Assessments of hedge effectiveness and measurements of hedge ineffectiveness are performed at least quarterly for ongoing effectiveness.
(n) Bank-Owned Life Insurance ("BOLI")
The Company 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 that is probable at settlement. Increases to cash surrender values are recorded as a component of "other noninterest income" on the consolidated statements of income.
(o) Share-Based Compensation
The Company has an equity compensation plan providing for the grant of equity awards, which is described more fully in Note 16. The Company uses the fair value method of recognizing expense for share-based compensation, whereby compensation cost is measured at the grant date based on the value of the award and is recognized on a straight-line basis over the vesting period. Compensation expense relating to equity awards is reflected in net income as part of "salaries and employee benefits" on the consolidated statements of income.
(p) Income Taxes
The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies by jurisdiction and entity in making this assessment.
(q) Comprehensive Income
In addition to net income for the period, comprehensive income for the Company consists of changes in unrealized holding gains and losses on investments classified as available-for-sale and changes in fair value of the effective portion of derivative financial instruments designated as cash flow hedges. The changes are reported net of income taxes and reclassification adjustments.
(r) Acquisitions
Accounting principles generally accepted in the United States of America ("US GAAP") require that the acquisition method of accounting, formerly referred to as the purchase method, be used for all business combinations and that an acquirer be identified for each business combination. Under US GAAP, the acquirer is the entity that obtains control of one or more businesses in the business combination, and the acquisition date is the date the acquirer achieves control. US GAAP requires that the acquirer recognize the fair value of assets acquired, liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date.
(s) Basic and Diluted Net Income Per Share
Basic net income per share excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the net income of the Company. Diluted net income per share is computed by dividing net income by the total of the weighted average number of shares outstanding plus the dilutive effect of the outstanding options, warrants and restricted stock awards.
(t) Recent Accounting Pronouncements
In January 2013, the Financial Accounting Standards Board (FASB) issued ASU 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. This ASU limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods. This guidance did not impact the Company's financial condition or results of operations and only resulted in additional disclosures.
In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the reporting of reclassifications out of accumulated other comprehensive income of various components. ASU 2013-02 requires entities to disclose in a single location, either on the face of financial statement that reports net income or in the notes, the effects of reclassification out of accumulated other comprehensive income (AOCI). For items reclassified out of AOCI and into net income in their entirety, such as realized gains or losses on available-for-sale securities reclassified into net income on sale, entities must disclose the effect on the reclassification on each affected net income item. For AOCI reclassification items that are not reclassified in their entirety into net income, such as actuarial gains or losses amortized into pension cost that may be capitalized into inventory or other assets, entities must provide a cross reference to other required U.S. GAAP disclosures. ASU 2013-02 was effective for the Company on January 1, 2013. This guidance did not have a significant impact on the Company’s financial condition or results of operations, and resulted in additional disclosures.
In July 2013, the FASB issued Accounting Standards Update (ASU) 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in ASU 2013-10 permit the Fed Funds Effective Swap Rate (also referred to as the Overnight Index Swap Rate) to be used as a benchmark interest rate for hedge accounting in addition to United States Treasury Obligations Rate (UST) and the London Interbank Offered Rate (LIBOR). The amendments also remove the restriction on using different benchmark rates for similar hedges. The standard is effective prospectively for qualifying new or re-designated hedging relationships entered into on or after July 17, 2013. The guidance did not have a material impact on the Company's financial position, results of operations or disclosures.
In January 2014, the FASB issued Accounting Standards Update (ASU) 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The new ASU clarifies when an in substance repossession or foreclosure occurs – that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The ASU requires a creditor to reclassify a collateralized consumer mortgage loan to real estate property upon obtaining legal title to the real estate collateral, or when the borrower voluntarily conveys all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. The Company does not expect the impact of this
guidance to be material to its financial position, results of operations, or disclosures.

	At December 31, 2013, the Company held 31 investment securities that were in an unrealized loss position. Market changes in interest rates and credit spreads may result in temporary unrealized losses as the market price of securities fluctuates. 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. As of December 31, 2013, there was no intent to sell any of the securities 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):
		31-Dec
		2013		2012			2011
	Proceeds from sales and calls	$	28,636	$	24,303		$	57,851

	Net realized gains (losses) on sales and calls of securities available-for-sale	$	1,081	$	318		$	(54	)
	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 $132.0 million and $126.6 million at December 31, 2013 and December 31, 2012, respectively, were pledged to secure public deposits, repurchase agreements, net counterparty exposure and certain borrowing arrangements.

	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 lives of the loans on a level yield basis.

	Description of segment and class risks
	Each of our portfolio segments and the classes within those segments are subject to risks that could have an adverse impact on the credit quality of our loan portfolio. Management has identified the most significant risks as described below which are generally similar among our segments and classes. While the list is not exhaustive, it provides a description of the risks that management has determined are the most significant. At December 31, 2013, approximately 18.6% of our outstanding loan portfolio is covered under FDIC loss share agreements and does not represent the same risk of loss as the noncovered loan portfolio. The risks associated with covered loans are generally consistent with the risks identified for commercial and noncommercial loans and the classes of loans within those segments. In addition to the risks associated with segments and classes, risks specifically associated with covered loans are also described below.
	Real Estate Loans
	Loans secured by real estate are the principal component of our loan portfolio. Real estate loans are subject to the same general risks as other loans and are particularly sensitive to fluctuations in interest rates and the value of real estate. Fluctuations in these factors, as well as others arising after a loan has been made, could negatively affect a borrower's cash flow, creditworthiness and ability to repay the loan. When we make new real estate loans, we typically obtain a security interest in the real estate, as well as other available credit enhancements, to increase the likelihood of the ultimate repayment of the loan. To control concentration risk, we monitor collateral type concentrations within this portfolio.
	In addition to these common risks for the majority of our real estate loans, additional risks are inherent in certain of our classes of real estate loans.
	Commercial Real Estate
	Commercial real estate loans consist of commercial construction and land development loans and other commercial real estate loans. Commercial construction and land development loans are highly dependent upon the supply and demand for commercial real estate in the markets we serve as well as the demand for newly constructed residential homes and lots that our customers are developing. Construction and development loans generally carry a higher degree of risk than long-term financing of existing properties because repayment depends upon the ultimate completion of the project and usually on the subsequent lease-up and/or sale of the property. Additionally, deterioration in demand could result in significant decreases in the underlying collateral values and make repayment of the outstanding loans more difficult for our customers.
	Other commercial real estate loans consist primarily of loans secured by multifamily housing and other nonfarm nonresidential properties such as retail, office and hotel/motel. These loans typically have terms of five years or less, although payments may be structured on a longer amortization basis. We evaluate each borrower on an individual basis and attempt to determine the business risks and credit profile of each borrower. The primary risk associated with loans secured with income-producing property is the inability of that property to produce adequate cash flow to service the debt. High unemployment, generally weak economic conditions and/or an oversupply in the market may result in our customer having difficulty achieving adequate occupancy rates.
	Commercial and Industrial Loans
	Commercial and industrial loans include loans to individuals and businesses for commercial purposes in various lines of business, including manufacturing industries and professional service industries. Repayment is primarily dependent on the ability of the borrower to achieve business results consistent with those projected at loan origination resulting in cash flow sufficient to service the debt. To the extent that a borrower's business results are significantly unfavorable versus the original projections, the ability for the loan to be serviced on a basis consistent with the contractual terms may be at risk. While these loans may have real estate as partial collateral, they are generally considered to have greater risk than first or second mortgages on real estate because these loans may be unsecured or, if they are secured, the value of the non-real estate collateral may be difficult to assess and more likely to decrease than real estate, and the control of the collateral is more at risk.
	Owner-occupied loans consist of loans secured by nonfarm nonresidential properties such as office and industrial properties, churches, convenience stores and restaurants occupied by an affiliated tenant. Like commercial and industrial loans, repayment is primarily dependent on the ability of the operating company to achieve business results consistent with those projected at loan origination resulting in cash flow sufficient to service the debt. Adverse changes in the business's results, specifically declines in cash flows, could jeopardize the ability for the loan to be serviced in accordance with the contractual terms.
	Residential Real Estate
	Residential real estate loans are typically to individuals and are secured by owner-occupied and investor-owned 1-4 family residential property. We generally originate and hold short-term first mortgages, traditional second mortgages and home equity lines of credit. We originate and sell longer-term mortgages in the secondary market. Significant and rapid declines in real estate values can result in residential mortgage loan borrowers having debt levels in excess of the current market value of the collateral.
	Consumer
	The consumer loan portfolio includes loans to individuals for personal, family and household purposes, including secured and unsecured installment loans and revolving lines of credit. Consumer loans not secured by real estate are generally considered to have greater risk than first or second mortgages on real estate because they may be unsecured, or, if they are secured, the value of the collateral may be difficult to assess and more likely to decrease in value, and is more difficult to control, than real estate.
	Covered loans
	The risks associated with covered loans are generally consistent with the risks identified for commercial and noncommercial loans and the classes of loans within those segments. An additional substantive risk with respect to covered loans relates to the FDIC loss share agreements, specifically the ability to receive timely and full reimbursement from the FDIC for losses and related expenses that we believe are covered by the loss share agreements. Further, these loans were underwritten by other institutions with weaker lending standards. Therefore, there is a significant risk that the loans were not adequately supported by the paying capacity of the borrower or the values of underlying collateral at the time of origination. Management separately monitors the covered loan portfolio and periodically evaluates the recorded investment in these loans in comparison to actual losses. This evaluation is made to determine whether additional impairment exists.

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 appropriate 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. A reduction in the loan value, through a provision for loan losses, and an increase in the FDIC receivable, through an adjustment to income, are taken immediately. An increase in the loan value and a reduction in the FDIC receivable results in the reversal of the previously recorded allowance for loan losses and prospective yield adjustment over the remaining life of each asset.

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 this table 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 losses on covered loans plus the discounts to the unpaid principal balances reflected in the recorded investment of each loan.

At December 31, 2013, the Company elected to perform a qualitative assessment to determine if it was more likely than not that the fair value exceeded carrying value. The qualitative assessment indicated that it was more likely than not that the fair value exceeded its carrying value, resulting in no impairment.
	Amortization expense for core deposit and other intangibles for the next five years is expected to be as follows (dollars in thousands):

	Retail repurchase agreements, defined as securities sold under repurchase agreements from our customers, totaled $1.2 million and $4.8 million as of December 31, 2013 and 2012, respectively. These retail repurchase agreements are secured short term borrowings from customers, which may be drawn on demand. The agreements bear interest rates determined by the Company. The weighted average rate of the outstanding agreements was .10% at December 31, 2013 and 2012. The Company had pledged securities with an approximate market value of $2.5 million and $7.7 million as collateral at December 31, 2013 and 2012, respectively.

	The Company has several participation agreements with various provisions regarding collateral position, pricing and other matters where the junior participation interests were sold. The terms of the agreements do not convey proportionate ownership rights with equal priority to each participating interest and entitles the Company to receive principal and interest payments before other participating interest holders. Given the participations sold do not qualify as participating interests, they do not qualify for sale treatment in accordance with generally accepted accounting principles. As a result, the Company recorded the transactions as secured borrowings. At December 31, 2013, the balance of the secured borrowings was $5.7 million, an increase of approximately $3.2 million from December 31, 2012. The loans are recorded at their gross balances outstanding in noncovered loans on the consolidated balance sheet.

	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 and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated in qualifying hedging relationships. 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
		Asset Derivatives										Liability Derivatives
		December 31, 2013						December 31, 2012				December 31, 2013						December 31, 2012

	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. As of December 31, 2013, the Company had 75 interest rate swaps with an aggregate notional amount of $152.0 million that 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, have a five-year life and notional value of $200.0 million. The Company had no active derivative contracts outstanding at December 31, 2012 that were designated as cash flow hedges.
	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 and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2013, such derivatives were used to hedge the variable cash outflows associated with existing liabilities. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. No hedge ineffectiveness was recognized on the Company's cash flow hedge during the year ended December 31, 2013.
	Amounts reported in accumulated other comprehensive income (AOCI) related to derivatives will be reclassified to interest expense as interest payments are received on the Company's cash flow hedge. During the next twelve months, the Company estimates that $259,000 will be reclassified as a decrease to net interest income.
	For derivatives so designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. The change in fair value of the effective portion of cash flow hedges is accounted for in other comprehensive income rather than net income and the premium paid to purchase the cap is amortized into interest expense over the life of the cap.
	During the years ended December 31, 2013, 2012, and 2011, the Company recognized net gains (losses) of $840,000, $(165,000), and $(550,000), respectively, related to hedge ineffectiveness of the fair value hedging relationships. The Company also recognized a net reduction in interest income of $1.5 million, $698,000, and $189,000 for the years ended December 31, 2013, 2012, and 2011, respectively, 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 a net gain (loss) of $125,000 and $(8,000) in noninterest income for the years ended December 31, 2013 and 2012, respectively, related to the unamortized basis in the hedged items. The Company did not recognize a gain or loss in 2011 as there were no early terminations.

	Credit-risk-related Contingent Features
	The Company manages credit exposure on derivatives transactions by entering into a bi-lateral 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 December 31, 2013, there were no derivatives in a net liability position.
	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 would be required to settle its obligations under the agreements.

	Stock Warrants
	The Company has outstanding warrants purchased by executive officers, directors and certain members of senior management. Warrant holders have the right to purchase one share of the Company's common stock at strike prices ranging from $5.00 to $12.00 per share through the ten-year contractual period. The warrants were fully exercisable as of the purchase date; however, they were subject to repurchase agreements should the holder leave his or her employment or role as a director. The repurchase was at the Company's option ranging from a price of $2.00 to $2.32 per warrant depending on the specific warrant agreement as well as $12.00 per share for exercised warrants. If the warrant holder exercised the warrant for shares within the repurchase period, the common stock issued was subject to repurchase until the agreement expired. The repurchase option expired three years from the date of each agreement; therefore, subsequent to November 30, 2013, no remaining unexercised or exercised warrants were subject to repurchase. During 2013 and 2012, there was no new warrant activity and the repurchases during those periods were for unexercised warrants.

Share-Based Compensation	'
	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 stock for issuance in accordance with the Plan terms. The Plan provides for the granting of Incentive Stock Options, Non-Qualified Stock Options, Performance Awards, Restricted Stock, Restricted Stock Units, Stock Appreciation Rights, Bonus Stock and Stock Awards, or any combination of the foregoing, as the Compensation Committee determines is best suited to the circumstances of the particular individual.
	Stock Option Awards
	Option awards are granted with an exercise price equal to or greater than the market price of the Company's common stock at the date of grant. The options include a vesting period, usually three years, and a ten-year contractual period. Certain option grants provide for accelerated vesting if there is a change in control of the Company or certain other conditions are met, as defined in the Plan document. The Company shall, at all times during the term of the Plan, retain as authorized and unissued shares in the Company's treasury, at least the number of shares required to satisfy option exercises. Currently, the Company has a sufficient number of shares allocated to satisfy expected share option exercises.
	During 2013, the Company's Board of Directors approved the accelerated vesting of an aggregate of 28,918 unvested stock options upon the retirement of the award holders. The accelerated vesting triggered a modification to the award agreements, the original grants were forfeited and additional grants were awarded based on the new vesting terms. The additional grants awarded were done so at the same exercise price as the original grants. The fair value of each option award is estimated as of the grant date using the Black-Scholes option-pricing model. The significant assumptions made and resulting grant-date fair values in utilizing the option-pricing model are noted in the following table.
		Years Ended December 31,

	Expected dividend yield	—		%		—		%	—		%

	Expected term (in years)	2.5				—			6.5
	Weighted-average grant-date fair value	$	3.48			$	—		$	7.74
	The 2013 expected volatility, used for the modification of the agreements, is based on the average historical volatility of the Company's stock price. The 2011 expected volatility, used for the original terms of the agreements, is based on the peer group population's stock price. The expected dividend yield is estimated using the current annual dividend level and most recent stock price of the Company’s common stock at the date of grant. The risk-free interest rate is determined by using the U.S. Treasury rate for the expected life at the time of grant. The expected term represents the period of time that the stock options granted are expected to be outstanding.
	For the years ended December 31, 2013, 2012 and 2011, the Company recognized compensation expense related to stock options of $14,000, $69,000 and $17,000, respectively, in the Company's consolidated statements of income. The total recognized tax benefit related to the share-based compensation was $5,000, $24,000 and $6,000 for 2013, 2012 and 2011, respectively. The amount of compensation expense was determined based on the fair value of options at the time of grant, multiplied by the number of options granted that were expected to vest, which was then amortized over the vesting period. There was no unrecognized compensation cost related to stock options as of December 31, 2013 as all options were vested.

	The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2013. This amount changes based on changes in the market value of the Company’s stock.
	Restricted Stock Awards
	The Company issued restricted stock to certain officers under the Plan. The Plan allows for the issuance of restricted stock awards that may not be sold or otherwise transferred until certain restrictions have lapsed. The holders of the restricted stock receive dividends, if applicable, and have the right to vote the shares. The fair value of the restricted stock shares awarded under the Plan is recorded as unearned share-based compensation. The unearned compensation related to these awards is amortized to compensation expense over the vesting period, generally three to five years. The total share-based compensation expense for these awards is determined based on the market price of the Company's common stock at the date of grant applied to the total number of shares granted and is amortized over the vesting period. During 2013, the Company's Board of Directors approved the accelerated vesting of an aggregate of 14,700 shares of restricted stock upon the retirement of the award holders. The accelerated vesting triggered a modification to 12,700 awards, which required a forfeiture and reissuance of the awards at a new fair value. The fair value was calculated using the Company's stock price on the reissue date.
	Compensation expense recognized in the Company's consolidated statements of income for restricted stock was $1,307,000, $710,000 and $171,000 at December 31, 2013, 2012 and 2011, respectively. The total recognized tax benefit related to the share-based compensation was $444,000, $251,000 and $61,000 for 2013, 2012 and 2011, respectively. Total unrecognized compensation cost related to nonvested share-based compensation was $3.2 million at December 31, 2013 and is expected to be recognized over a weighted-average period of 3.4 years.
	The following table represents a summary of the non-vested restricted stock award activity:
		December 31, 2013
		Shares			Weighted Average Grant Date Fair Value
	Balance, beginning of year	279,155			$	15.37

	Earned and issued	(21,700	)		16.01
	Balance, end of year	431,269			$	15.81
	Restricted stock awards of 181,814 shares, 174,000 shares, and 109,655 shares, respectively, were granted during 2013, 2012, and 2011 with a weighted-average grant date fair value of $16.33, $16.31 and $13.87, respectively.

	Employee Benefit Plan
	The Company offers a defined contribution 401(k) Profit Sharing Plan (the "401(k) Plan”) that covers substantially all employees meeting certain eligibility requirements. The 401(k) Plan allows employees to make pre-tax or Roth after-tax salary deferrals to the 401(k) Plan and the Company matches these employee contributions on a discretionary basis equal to a uniform percentage of the salary deferrals. During 2013, 2012 and 2011, the Company matched employee contributions dollar-for-dollar up to 5% of eligible compensation, subject to 401(k) Plan and regulatory limits. Effective January 1, 2013, participants receive matching contributions the first quarter after completing three months of service and matching contributions made after January 1, 2013 are fully vested, regardless of years of service. In 2012 and 2011, participants received matching contributions after completing one year of service and matching contributions made during those years begin vesting after one year of service and are fully vested after five years of service. Compensation expense related to the 401(k) Plan totaled $1.6 million, $1.4 million, and $1.1 million in 2013, 2012 and 2011, respectively.

	Regulatory Capital Requirements
	The Company and the Bank are 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 and the Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
	Measures of regulatory capital are an important tool used by regulators to monitor the financial health of financial institutions. The primary quantitative measures used to gauge capital adequacy are the ratios of total and Tier 1 regulatory capital to risk-weighted assets (risk-based capital ratios) and the ratio of Tier 1 capital to average total assets (leverage ratio). Failure to meet various capital requirements can initiate regulatory action that could have a direct material effect on the Company and the Bank.
	At December 31, 2013 and 2012, the Company and the Bank were categorized as well capitalized under the regulatory framework for prompt corrective action. To be well-capitalized, the Company and the Bank must maintain total risk-based, Tier I risk-based and Tier I leverage ratios as set forth in the table below. There are no conditions or events that have occurred subsequent to year-end that would change the Company and the Bank's classification from well-capitalized. The Company's and the Bank's actual ratios for the periods indicated are as follows (dollars in thousands):

	The Company and the Bank entered into a Capital Maintenance Agreement with the FDIC that terminated on December 31, 2013. Under the terms of the Capital Maintenance Agreement, the Bank was 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 fell below 10%, or its risk-based capital ratio fell below 12%, the Company would have been 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 Bank was in compliance with the Capital Maintenance Agreement at December 31, 2013 and 2012. The Company and the Bank have agreed with the FDIC to enter into a new Capital Maintenance Agreement, which will require the Bank to maintain the same capital requirements as the prior Capital Maintenance Agreement, through July 2016.
	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. As of December 31, 2013, the Bank had no dividend capacity to pay dividends to the Company without prior regulatory approval.
	At December 31, 2013, the Company had $56.4 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. On March 19, 2013, June 18, 2013, September 17, 2013, and December 17, 2013, the Company paid a cash dividend of $.03 per common share to the Company's shareholders.
	Other Regulatory Matters
	At December 31, 2013 and 2012, the Company had required reserve balances at the Federal Reserve Bank of $76.4 million and $66.2 million, respectively.

	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. The Company uses the same credit policies in making commitments and conditional obligations as for on-balance-sheet instruments.
	A summary of the Company's commitments is as follows (dollars in thousands):
		December 31
		2013		2012
	Commitments to extend credit:
	Fixed	$	9,848	$	8,188
	Variable	290,079		248,310
	Financial standby letters of credit:
	Fixed	379		437
	Variable	1,274		1,399
	Total	$	301,580	$	258,334
	The fixed rate loan commitments have maturities ranging from 1 month to 9 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 years ended December 31, 2013 and 2012, 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 December 31, 2013, 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 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 considered impaired are loans for which, based on current information and events, it is probable that the creditor 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 December 31, 2013 and 2012, 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 a principal balance of $2.3 million with a valuation allowance of $303,000 at December 31, 2013. The Company also had one loan classified as a troubled debt restructuring that was not collateral dependent at December 31, 2013 with a principal balance of $73,000. The fair value of the troubled debt restructuring was measured by discounting expected future cash flows at the effective interest rates, or the original contractual loan rate, resulting in a valuation allowance totaling $11,000.
Noncovered impaired collateral dependent loans that are measured for impairment using the fair value of collateral for collateral dependent loans, had a principal balance of $3.5 million with a valuation allowance of $1.1 million at December 31, 2012. The Company also had two loans that were classified as troubled debt restructurings that were not collateral dependent at December 31, 2012 with principal balances totaling $1.3 million. The fair values of the troubled debt restructurings were measured by discounting expected future cash flows at the effective interest rate, or the original contractual loan rate, resulting in valuation allowances totaling $189,000.
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.

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 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 December 31, 2013 and 2012.

Cash and Cash Equivalents
The carrying amount approximates fair value because of the short maturity of these instruments.
Mortgage Loans Held for Sale
Mortgage loans held for sale are recorded at the lower of cost or fair value. Estimated fair value is determined on the basis of existing forward commitments, or the current market value of similar loans. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.
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. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan when there is reasonable expectation about the amount and timing of such cash flows.
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 cash flows based on the maturity date. 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.

Nature of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenue and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the estimates used for fair value acquisition accounting and the FDIC receivable for loss share agreements, and the assessment for other than temporary impairment of investment securities. In connection with the determination of the allowance for loan losses and the value of real estate owned, management obtains independent appraisals for significant properties. In connection with the assessment for other than temporary impairment of investment securities, management obtains fair value estimates by independent quotations, assesses current credit ratings and related trends, reviews relevant delinquency and default information, assesses expected cash flows and coverage ratios, assesses the relative strength of credit support from less senior tranches of the securities, reviews average credit score data of underlying mortgages, and assesses other current data. 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.
	A substantial portion of the Company's loans are secured by real estate located in its market area. Accordingly, the ultimate collectability of a substantial portion of the Company's loan portfolio is susceptible to changes in the real estate market conditions of this market area.
	As defined by authoritative guidance, segment disclosures require reporting information about a company's operating segments using a “management approach.” Reportable segments are identified as those revenue-producing components for which separate financial information is produced internally and which are subject to evaluation by the chief operating decision maker in deciding how to allocate resources to segments. The Company operates as one reportable segment.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents, as presented in the consolidated financial statements, includes cash on hand, cash items in process of collection and interest-bearing deposits with other financial institutions with maturities less than 90 days.
Investments	'
	Investments
	Management determines the appropriate classifications of investment securities at the time of purchase and reevaluates such designation as needed. At December 31, 2013 and 2012, the Company classified all of its investment securities as available-for-sale. Investments available-for-sale are reported at fair value, as determined by independent quotations. Purchase premiums and discounts on investment securities are amortized and accreted to interest income using the effective interest rate method over the remaining lives of the securities, taking into consideration assumed prepayment patterns. Realized gains and losses are derived using the specific identification method for determining the cost of securities sold and are recognized on the trade date.
	Unrealized holding losses, other than those determined to be other than temporary, and unrealized holding gains are excluded from net income and are reported, net of tax, in other comprehensive income and in accumulated other comprehensive income, a separate component of shareholders' equity. A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for that security. At December 31, 2013 and 2012, the Company did not have any securities with other than temporary impairment.
	Investment in stock of the Federal Home Loan Bank ("FHLB") is required of every federally insured financial institution which utilizes the FHLB's services. The investment in FHLB stock is included in "other assets" at its original cost basis, as cost approximates fair value since there is no readily determinable market value for such investments.
Noncovered Loans	'
	Noncovered Loans
	Loans, excluding loans covered by FDIC loss share agreements, that management has the intent and ability to hold for the foreseeable future, until maturity, or payoff are reported at their principal amounts outstanding, net of unearned income, deferred loan fees and origination costs, unamortized premiums or discounts on purchased loans, and the allowance for loan losses. Interest income is recognized using the simple interest method on the daily balance of their principal amount outstanding. Unearned income, primarily arising from deferred loan fees, net of certain origination costs is amortized over the lives of the underlying loans using the effective interest rate method.
	Past due status is based on the contractual terms of the loan agreement. Generally, the accrual of interest income is discontinued and loans are placed on nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal. Interest previously accrued but not collected is reversed against current period interest income when such loans are placed on nonaccrual status. Interest on nonaccrual loans when ultimately collected is recorded as a principal reduction. Nonaccrual loans are returned to accrual status when all principal and interest amounts contractually due are brought current. In addition, the future payments must be reasonably assured along with a period of at least six months of repayment performance by the borrower depending on the contractual payment terms. When it has been determined that a loan cannot be collected in whole or in part, then the uncollectible portion will be charged-off.
	The Company considers a loan 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. Additionally, loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings ("TDRs") and are included in impaired loans. The Company's policy requires that all impaired loans with contractual balances of $500,000 and greater be individually reviewed for impairment. Loans are reviewed for impairment based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or the loan's observable market price, or the fair value of the collateral less disposal costs, as applicable, if the loan is collateral dependent. The Company's policy requires that large pools of smaller balance homogeneous loans, such as consumer, residential and installment loans, be collectively evaluated for impairment by the Company. Impairment losses are included in the allowance for loan losses through a charge to the provision for loan losses. All loans considered impaired are placed on nonaccrual status in accordance with policy. The interest portion of cash receipts on impaired loans are recorded as income when received unless full recovery of principal is in doubt whereby cash received is recorded as a reduction to the Company's recorded investment in the loan.
	All impaired loans are reviewed, at minimum, on a quarterly basis. Reviews may be performed more frequently if material information is available before the next scheduled quarterly review. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. The discounts may include the following: length of time to market and sell the property, as well as expected maintenance costs, insurance and taxes and real estate commissions on sale.
Covered Loans	'
	Covered Loans
	Covered loans, defined as loans covered by loss share agreements with the FDIC, 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, if appropriate, an accretable discount. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan when there is reasonable expectation about the amount and timing of such cash flows. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is the nonaccretable discount, which is excluded in the carrying amount of acquired loans. Expected prepayments are treated consistently for cash flows expected to be collected and projections of contractual cash flows such that the nonaccretable discount is not affected. Similarly, the difference between actual prepayments and expected prepayments do not affect the nonaccretable discount. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior applicable loss provisions or a reclassification of the difference from nonaccretable to accretable with a positive impact on the accretable discount.
	The Company accounts for performing loans acquired in business combinations using the contractual cash flows method whereby premiums and discounts are recognized using the interest method. There is no allowance for loan losses established at the acquisition date for purchased performing loans. A provision for loan losses is recorded for any further deterioration in these loans subsequent to the acquisition.
	All loans acquired in failed bank transactions are considered to have evidence of credit deterioration as limited due diligence is afforded which does not allow a sufficient detailed review to classify the acquired loans into credit deterioration and performing categories.
	At the time of acquisition, loans with evidence of credit deterioration are either accounted for as specifically-reviewed or as part of a loan pool. Loan pools are created by grouping loans with similar risk characteristics, the intent being to create homogeneous pools. Loans are grouped into pools based on a combination of various factors including product type, cohort, risk classification and term. Loans remain in the assigned pool until they are resolved. Gains and losses are deferred and retained in the pools until the pool closes, which is either when all the loans are resolved or the pool’s recorded investment reaches zero.
Allowance for Loan Losses	'
	Allowance for Loan Losses ("ALL")
	The ALL is a valuation allowance for probable incurred credit losses. The ALL is adjusted through provisions for loan losses charged or credited to operations. All or portions of loans, excluding covered loans, deemed to be uncollectible are charged against the ALL when management believes that collectability of all or some portion of outstanding principal is unlikely. Subsequent recoveries, if any, of loans previously charged-off are credited to the ALL. The ALL for noncovered loans is determined through consideration of such factors as changes in the nature and volume of the portfolio, overall portfolio quality, delinquency trends, adequacy of collateral, loan concentrations, specific problem loans, and economic conditions that may affect the borrowers' ability to pay.
	The ALL for noncovered loans consists of specific and general components. The specific component relates to loans that are individually identified as impaired. The general component covers nonimpaired loans and is based on historical loss experience adjusted for current environmental factors. This qualitative analysis requires judgment by management and is subject to continuous validation. The Company's noncovered loan portfolio has been originated over the past several years. The portfolio has been stringently underwritten and has experienced minimal losses. Beginning with fourth quarter 2011, the Company uses its own historical loss data in the allowance calculation.
	Management separately monitors the covered loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the acquisition date fair value. To the extent that the revised loss estimate exceeds the loss estimate established in the determination of the acquisition date fair values, such deterioration will result in additional provision for loan losses charged to expense.
	The ALL is maintained at a level management believes is adequate to absorb probable incurred losses. The Company has recorded all known and inherent losses that are both probable and reasonable to estimate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's allowance for loan losses. Such agencies may require the Company to adjust the allowance based on their judgment about information available to them at the time of their examination.
	The company assesses the adequacy of the ALL quarterly with respect to noncovered and covered loans. The assessment begins with a standard evaluation and analysis of each loan. All loans are consistently graded and monitored for changes in credit risk and possible deterioration in the borrower's ability to repay the contractual amounts due under the loan agreement.
	If a loan is impaired, under generally accepted accounting principles, the Company may measure the loss, or expected cash flow, either by:
	-1	the observable market price of the loan;
	-2	the present value of expected future cash flows discounted at the loan's effective interest rate; or
	-3	the fair value of the collateral if the loan is collateral dependent.
	Management evaluates the results of the ALL procedures performed, including the results of testing, and makes a conclusion regarding the appropriateness of the ALL in its entirety.
	Allowance for loan losses for noncovered loans:    The ALL for noncovered loans consists of two components:
	-1	a specific amount against identified credit exposures where it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreements; and
	-2	a general amount, based upon historical losses, that is then adjusted for qualitative factors representative of various economic indicators and risk characteristics of the loan portfolio.
	Management establishes the specific amount by examining impaired loans. The majority of the Company's impaired loans are collateral dependent; therefore, nearly all of the specific allowances are calculated based on the fair value of the collateral less disposal costs, if applicable.
	Management establishes the general amount by taking the remaining loan portfolio (excluding those impaired loans discussed above) with allocations based on historical losses. The calculation of the general amount is subjected to stress factors that are somewhat subjective. The stress testing attempts to correlate the historical loss rates with current economic factors and current risks in the portfolio. The stress factors consist of:
	-1	economic factors including changes in the local or national economy;
	-2	the depth of experience in lending staff;
	-3	any concentrations of credit (such as commercial real estate);
	-4	asset quality trends; and
	-5	seasoning of the loan portfolio.
	After assessing the applicable factors, the remaining amount is evaluated based on management's experience and the level of the noncovered ALL is compared with historical trends and peer information as a reasonableness test.
	Allowance for loan losses for covered loans: On the date of acquisition, management estimates the expected credit loss in the acquired loan portfolio and records the present value of the expected cash flows as the fair value of the acquired loans. Management determines which covered loans are placed in homogenous risk pools or reviewed specifically as part of the periodic cash flow re-estimation process. If a loan is placed in a pool, the overall performance of the pool will determine if any future ALL is required.
	The covered loan ALL analysis represents management's estimate of the potential impairment of the acquired loan portfolio over time. Typically, decreased cash flows result in impairment, while increased cash flows result in a full or partial reversal of previously recorded impairment and potentially the calculation of a higher effective yield. Higher actual cash flows than expected will result in a greater pay down of the covered loan, which decreases the recorded investment and therefore may cause an impairment reversal or higher effective yield. Lower actual cash flows than expected will result in a smaller pay down of the loan receivable and a higher recorded investment which may cause further impairment.
	If actual losses exceed the estimated losses, provision for loan losses is recorded on covered loans as an expense on the consolidated statement of income. The Company also records an amount that will be recovered, under the related FDIC loss share agreements, as a reduction of the provision for loan losses on the consolidated statement of income.
	Management reviews the assumptions used in the calculation of the updated expected cash flows, evaluates the impairment based on management's experience, and uses a third party to obtain peer information as part of its reasonableness test for the covered loan ALL.
Mortgage Loans Held for Sale	'
	Mortgage Loans Held for Sale
	Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Estimated fair value is determined on the basis of existing forward commitments or the current market value of similar loans. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.
Other Real Estate Owned	'
	Other Real Estate Owned
	Other real estate owned 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.
	Real estate acquired through foreclosure of noncovered loans, consisting of properties obtained through foreclosure proceedings or acceptance of a deed in lieu of foreclosure, is reported on an individual asset basis at fair value, less disposal costs. Fair value is determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources. When properties are acquired through foreclosure of noncovered loans, any excess of the loan balance at the time of foreclosure over the fair value of the real estate held as collateral is recognized and charged to the allowance for loan losses. Based upon management's evaluation of the real estate acquired through foreclosure, additional expense, when necessary, is recorded in current period earnings in an amount sufficient to reflect any estimated declines in fair value. Gains or losses recognized on the disposition of the properties are recorded in net costs of operations of other real estate in the consolidated statements of income.
	Other real estate acquired through foreclosure of covered loans under loss share agreements with the FDIC is reported exclusive of expected reimbursement cash flows from the FDIC. Subsequent adjustments to the estimated recoverable value of covered other real estate result in a reduction of covered other real estate, and a charge to other expense, and an increase in the FDIC receivable for the estimated amount to be reimbursed, with a corresponding net offsetting amount recorded to other expense.
	Banking premises are transferred at the lower of carrying value or fair value, less estimated selling costs and any write-down is expensed as incurred.
	Costs of improvements to real estate are capitalized, while costs associated with holding the real estate are charged to operations. Costs associating with holding covered other real estate are charged to operations, net of any expected reimbursements from the FDIC relating to covered external expenses.
Premises and Equipment	'
	Premises and Equipment
	Premises and equipment are stated at cost, less accumulated depreciation, which is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of the assets range from 10 to 25 years for buildings and improvements and 3 to 15 years for furniture, fixtures, and equipment. Costs of improvements are capitalized and depreciated, while operating expenses are charged to current earnings.
Goodwill and other Intangible Assets	'
	Goodwill and Other Intangibles
	Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangibles deemed to have an indefinite life are not amortized but instead are subject to review for impairment annually, or more frequently if deemed necessary. Also in connection with business combinations, the Company records core deposit intangibles, representing the value of the acquired core deposit base, and other identifiable intangible assets. Core deposit intangibles and other identifiable intangible assets are amortized over their estimated useful lives ranging up to 5 years.
FDIC Receivable for Loss Share Agreements	'
	FDIC Receivable for Loss Share Agreements
	The FDIC receivable for loss share agreements is measured separately from the related covered assets and is not contractually embedded in the assets or transferable should the assets be sold. Fair value at acquisition was estimated using projected cash flows related to loss share agreements based on the expected reimbursements for losses using the applicable loss share percentages and the estimated true-up payment at the expiration of the loss sharing agreements, if applicable. These cash flows were discounted to reflect the estimated timing of the receipt of the loss share reimbursements from the FDIC. Any applicable true-up payments owed to the FDIC for transactions that include claw-back provisions are discounted to reflect the estimated timing of the payment and such amount is netted against the FDIC receivable. The FDIC receivable is reviewed and updated prospectively as loss estimates related to indemnified assets change and as reimbursements are received or are expected to be received from the FDIC. Improvements in the credit quality or cash flows of loans (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the FDIC receivable, with such decreases being amortized into income over the remaining life of the loan or life of the loss share agreement, whichever is shorter.
Derivative Instruments and Hedging Activities	'
	Derivative Instruments and Hedging Activities
	The Company enters into derivative financial instruments to manage interest rate risk, facilitate asset/liability management strategies and manage other exposures. These instruments may include interest rate swaps and interest rate caps and floors. All derivative financial instruments are recognized on the consolidated balance sheets as other assets or other liabilities, as applicable, at estimated fair value. The Company enters into master netting agreements with counterparties and/or requires collateral to cover exposures. In most cases, counterparties post at a zero threshold regardless of rating.
	Interest rate swaps are agreements to exchange interest payments based upon notional amounts. Interest rate swaps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform. Option contracts involve rights to buy or sell financial instruments on a specified date or over a period at a specified price. These rights do not have to be exercised. Some option contracts such as interest rate caps, involve the exchange of cash based on changes in specified indices. Interest rate caps are contracts to hedge interest rate increases based on a notional amount. Interest rate caps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform.
	Derivative financial instruments are designated, based on the exposure being hedged, as either fair value or cash flow hedges. Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Under the fair value hedging model, gains or losses attributable to the change in fair value of the derivative instrument, as well as the gains and losses attributable to the change in fair value of the hedged item, are recognized in other noninterest income in the period in which the change in fair value occurs. Hedge ineffectiveness is recognized as other noninterest income to the extent the changes in fair value of the derivative do not offset the changes in fair value of the hedged item. The corresponding adjustment to the hedged asset or liability is included in the basis of the hedged item, while the corresponding change in the fair value of the derivative instrument is recorded as an adjustment to other assets or other liabilities, as applicable. Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. For cash flow hedge relationships, the effective portion of the gain or loss related to the derivative instrument is recognized as a component of accumulated other comprehensive income (loss). The ineffective portion of the gain or loss related to the derivative instrument, if any, is recognized in earnings as other noninterest income during the period of change. Amounts recorded in accumulated other comprehensive income (loss) are recognized in earnings in the period or periods during which the hedged item impacts earnings.
	The Company formally documents all hedging relationships between hedging instruments and the hedged items, as well as its risk management objective and strategy for entering into various hedge transactions. Methodologies related to hedge effectiveness and ineffectiveness are consistent between similar types of hedge transactions and typically include (i) statistical regression analysis of changes in the cash flows of the actual derivative and a perfectly effective hypothetical derivative, and (ii) statistical regression analysis of changes in the fair values of the actual derivative and the hedged item. The Company performs retrospective and prospective effectiveness testing using quantitative methods and does not assume perfect effectiveness through the matching of critical terms. Assessments of hedge effectiveness and measurements of hedge ineffectiveness are performed at least quarterly for ongoing effectiveness.
Bank-Owned Life Insurance	'
	Bank-Owned Life Insurance ("BOLI")
	The Company 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 that is probable at settlement. Increases to cash surrender values are recorded as a component of "other noninterest income" on the consolidated statements of income.
Share-Based Compensation	'
	Share-Based Compensation
	The Company has an equity compensation plan providing for the grant of equity awards, which is described more fully in Note 16. The Company uses the fair value method of recognizing expense for share-based compensation, whereby compensation cost is measured at the grant date based on the value of the award and is recognized on a straight-line basis over the vesting period. Compensation expense relating to equity awards is reflected in net income as part of "salaries and employee benefits" on the consolidated statements of income.
Income Taxes	'
	Income Taxes
	The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies by jurisdiction and entity in making this assessment.
Comprehensive Income	'
	Comprehensive Income
	In addition to net income for the period, comprehensive income for the Company consists of changes in unrealized holding gains and losses on investments classified as available-for-sale and changes in fair value of the effective portion of derivative financial instruments designated as cash flow hedges. The changes are reported net of income taxes and reclassification adjustments.
Acquisitions	'
	Acquisitions
	Accounting principles generally accepted in the United States of America ("US GAAP") require that the acquisition method of accounting, formerly referred to as the purchase method, be used for all business combinations and that an acquirer be identified for each business combination. Under US GAAP, the acquirer is the entity that obtains control of one or more businesses in the business combination, and the acquisition date is the date the acquirer achieves control. US GAAP requires that the acquirer recognize the fair value of assets acquired, liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date.
Basic and Diluted Net Income Per Share	'
	Basic and Diluted Net Income Per Share
	Basic net income per share excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the net income of the Company. Diluted net income per share is computed by dividing net income by the total of the weighted average number of shares outstanding plus the dilutive effect of the outstanding options, warrants and restricted stock awards.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In January 2013, the Financial Accounting Standards Board (FASB) issued ASU 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. This ASU limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods. This guidance did not impact the Company's financial condition or results of operations and only resulted in additional disclosures.
	In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the reporting of reclassifications out of accumulated other comprehensive income of various components. ASU 2013-02 requires entities to disclose in a single location, either on the face of financial statement that reports net income or in the notes, the effects of reclassification out of accumulated other comprehensive income (AOCI). For items reclassified out of AOCI and into net income in their entirety, such as realized gains or losses on available-for-sale securities reclassified into net income on sale, entities must disclose the effect on the reclassification on each affected net income item. For AOCI reclassification items that are not reclassified in their entirety into net income, such as actuarial gains or losses amortized into pension cost that may be capitalized into inventory or other assets, entities must provide a cross reference to other required U.S. GAAP disclosures. ASU 2013-02 was effective for the Company on January 1, 2013. This guidance did not have a significant impact on the Company’s financial condition or results of operations, and resulted in additional disclosures.
	In July 2013, the FASB issued Accounting Standards Update (ASU) 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in ASU 2013-10 permit the Fed Funds Effective Swap Rate (also referred to as the Overnight Index Swap Rate) to be used as a benchmark interest rate for hedge accounting in addition to United States Treasury Obligations Rate (UST) and the London Interbank Offered Rate (LIBOR). The amendments also remove the restriction on using different benchmark rates for similar hedges. The standard is effective prospectively for qualifying new or re-designated hedging relationships entered into on or after July 17, 2013. The guidance did not have a material impact on the Company's financial position, results of operations or disclosures.
	In January 2014, the FASB issued Accounting Standards Update (ASU) 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The new ASU clarifies when an in substance repossession or foreclosure occurs – that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The ASU requires a creditor to reclassify a collateralized consumer mortgage loan to real estate property upon obtaining legal title to the real estate collateral, or when the borrower voluntarily conveys all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. The Company does not expect the impact of this
	guidance to be material to its financial position, results of operations, or disclosures.

Financing Receivable Covered by Loss Sharing Agreements Credit Quality Indicators	'
	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 this table 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 losses on covered loans plus the discounts to the unpaid principal balances reflected in the recorded investment of each loan.
	The following table presents the risk grades of the covered loan portfolio, by class of loans, as of December 31, 2013 (dollars in thousands):
