Accounting Policies [Abstract]
Basis of Presentation and Recently Adopted Accounting Standards	NOTE 1: BASIS OF PRESENTATION AND RECENTLY ADOPTED ACCOUNTING STANDARDS Overview State Bank Financial Corporation (the “Company” or "we") is a bank holding company whose business is primarily conducted through its wholly-owned banking subsidiaries. At June 30, 2015, the Company had two wholly-owned bank subsidiaries, State Bank and Trust Company (“State Bank”) and First Bank of Georgia ("First Bank"). We operate a full service banking business and offer a broad range of commercial and retail banking products to our customers, primarily located in metropolitan Atlanta, middle Georgia and Augusta, Georgia. On July 24, 2015, First Bank was merged with State Bank. The accompanying unaudited consolidated financial statements for the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statement presentation. The interim consolidated financial statements included herein are unaudited, but reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the interim period presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the period ended June 30, 2015 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements and notes thereto and the report of our independent registered public accounting firm included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 . Certain amounts have been reclassified to conform to the current period presentation. The reclassifications had no effect on net income or shareholders’ equity as previously reported. Recently Adopted Accounting Standard for Mortgage Loans Held-for-Sale After we acquired First Bank in January 2015, we elected the fair value option of accounting for our mortgage loans held-for-sale which will be applied prospectively to all new mortgage loan originations. There have been no other significant changes to our critical accounting policies from those disclosed in our 2014 Annual Report on Form 10-K. The reader should refer to the notes to our consolidated financial statements in our 2014 Annual Report on Form 10-K for a full disclosure of all critical accounting policies. Loans held-for-sale include the majority of originated residential mortgage loans and certain Small Business Administration ("SBA") loans, which the Company has the intent and ability to sell. The Company has elected to account for residential mortgage loans held-for-sale under the fair value option. The fair value of committed residential mortgage loans held-for-sale is determined by outstanding commitments from investors and the fair value of uncommitted loans is based on current delivery prices in the secondary mortgage market. Origination fees and costs are recognized in earnings at the time of origination for residential mortgage loans held-for-sale. SBA loans held-for-sale are recorded at the lower of cost or market. Any loans subsequently transferred to the held for investment portfolio are transferred at the lower of cost or market at that time. For SBA loans, fair value is determined primarily based on loan performance and available market information. Origination fees and costs for SBA loans held-for-sale are capitalized as a part of the basis of the loan and are included in the calculation of realized gains and losses upon sale. Gains and losses on the sales of both mortgage loans and SBA loans held-for-sale are recognized, based on the difference between the net sales proceeds, including the estimated value associated with servicing assets or liabilities, and the net carrying value of the loans sold. Adjustments to reflect unrealized gains and losses resulting from changes in fair value of residential mortgage loans held-for-sale, as well as realized gains and losses at the sale of the residential mortgage loans, and SBA loans are classified in the Consolidated Statements of Operation as noninterest income from mortgage banking and SBA income. The loan sale agreements for loans sold from our mortgage loans held-for-sale portfolio generally require that we repurchase or indemnify the investors for losses or costs on loans we sell under certain limited conditions. Some of these conditions include underwriting errors or omissions, fraud or material misstatements by the borrower in the loan application or invalid market value on the collateral property due to deficiencies in the appraisal. In addition to these conditions, our loan sale contracts define a condition in which the borrower defaults during a short period of time, typically 120 days to one year, as an Early Payment Default ("EPD"). In the event of an EPD, we are required to return the premium paid by the investor for the loan as well as certain administrative fees, and in certain situations repurchase the loan or indemnify the investor. Any losses related to loans previously sold are charged against our recourse liability for mortgage loans previously sold. The recourse liability is based on historical loss experience adjusted for current information and events when it is probable that a loss will be incurred.

Recent Accounting and Regulatory Pronouncements [Abstract]
Recent Accounting Pronouncements	NOTE 2: RECENT ACCOUNTING PRONOUNCEMENTS In January 2014, the Financial Accounting Standards Board ("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 adoption of this guidance in the first quarter of 2015 did not have a material impact on the Company's results of operations or financial condition, although it did result in additional disclosures. For more information about these disclosures, refer to NOTE 7, Other Real Estate Owned. In June 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The new guidance aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. The amendments in the ASU require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. We adopted the amendments in this ASU effective January 1, 2015. At June 30, 2015, all of our repurchase agreements were typical in nature (i.e., not repurchase-to-maturity transactions or repurchase agreements executed as a repurchase financing) and are accounted for as secured borrowings. As such, the adoption of ASU No. 2014-11 did not have a material impact on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which changes the analysis that a reporting entity must perform to determine whether it should consolidate certain legal entities. The amendments in the standard affect limited partnerships and similar legal entities, evaluating fees paid to a decision maker or a service provider as a variable interest, the effect of fee arrangements on the primary beneficiary determination, the effect of related parties on the primary beneficiary determination, and certain investment funds. This guidance is effective for public business entities for fiscal years, and for interim fiscal periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures. In June 2015, the FASB issued amendments to clarify the Accounting Standards Codification (ASC), correct unintended application of guidance, and make minor improvements to the ASC that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments were effective upon issuance (June 12, 2015) for amendments that do not have transition guidance. Amendments that are subject to transition guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. The Company does not expect these amendments to have a material effect on its financial statements.

Acquisitions	NOTE 3: ACQUISITIONS Acquisition of Boyett Agency, LLC On February 26, 2015, State Bank entered into an Asset Purchase Agreement with Boyett Agency, LLC an independent insurance agency, pursuant to which State Bank acquired substantially all of the assets of Boyett Agency, LLC. The acquisition was not material to the financial results of State Bank. Acquisition of Georgia-Carolina Bancshares Inc. and First Bank of Georgia On January 1, 2015, we completed our merger with Georgia-Carolina Bancshares, Inc., the holding company for First Bank. In the merger, First Bank, a Georgia-state-chartered bank, became a wholly-owned subsidiary bank of the Company. Under the terms of the merger agreement, each share of Georgia-Carolina Bancshares, Inc. common stock was converted into the right to receive $8.85 in cash and .794 shares of the Company's common stock. Total consideration paid was approximately $88.9 million , consisting of $31.8 million in cash and $57.0 million in the Company's common stock. The merger of Georgia-Carolina Bancshares was accounted for under the acquisition method of accounting, using pushdown accounting. Assets acquired, liabilities assumed and consideration exchanged were recorded at their respective acquisition date fair values. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available.

Market changes in interest rates and credit spreads may result in temporary unrealized losses as market prices of securities fluctuate. The Company reviews its investment portfolio on a quarterly basis for indications of other than temporary impairment ("OTTI"). The severity and duration of impairment and the likelihood of potential recovery of impairment is considered along with the intent and ability to hold any impaired security to maturity or recovery of carrying value. More specifically, when analyzing the nonagency portfolio, the Company uses cash flow models that estimate cash flows on security-specific collateral and the transaction structure. Future expected credit losses are determined by using various assumptions, the most significant of which include current default rates, prepayment rates and loss severities. Credit information is available and modeled at the loan level underlying each security during the OTTI analysis; the Company also considers information such as loan to collateral values, FICO scores and geographic considerations, such as home price appreciation or depreciation. These inputs are updated quarterly or as changes occur to ensure that the most current credit and other assumptions are utilized in the analysis. If, based on the analysis, the Company does not expect to recover the entire amortized cost basis of the security, the expected cash flows are discounted at the security's initial effective interest rate to arrive at a present value amount. OTTI credit losses reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of these securities. At June 30, 2015 , there was no intent to sell any of the available-for-sale securities in an unrealized loss position, and it is more likely than not 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 for the periods presented (dollars in thousands) : Three Months Ended Six Months Ended June 30 June 30 Securities Available-For-Sale 2015 2014 2015 2014 Proceeds from sales and calls $ 74,162 $ 3,560 $ 301,887 $ 12,696 Gross gains on sales and calls $ 86 $ 12 $ 585 $ 23 Gross losses on sales and calls (145 ) — (264 ) — Net realized gains (losses) on sales and calls $ (59 ) $ 12 $ 321 $ 23 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 $345.0 million and $283.4 million at June 30, 2015 and December 31, 2014 , respectively, were pledged to secure public deposits and repurchase agreements. Investment securities with an aggregate fair value of $ 27.0 million at June 30, 2015 were pledged as collateral for repurchase agreements totaling $ 11.7 million at June 30, 2015 . The collateral consists of all residential mortgage-backed securities-agency with maturities of greater than three years . The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities which are accounted for as collateralized financing arrangements (i.e., secured borrowings). There were no repurchase agreements at December 31, 2014 .

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. Pass grades are from 1 to 4. Descriptions of the general characteristics of grades 5 and above are 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.

SBA Servicing Rights	NOTE 8: SBA SERVICING RIGHTS All sales of SBA loans, consisting of the guaranteed portion, are executed on a servicing retained basis. These loans, which are partially guaranteed by the SBA, are generally secured by business property such as real estate, inventory, equipment and accounts receivable. During the three and six months ended June 30, 2015 , the Company sold SBA loans with unpaid principal balances totaling $13.4 million and $19.5 million , respectively, and recognized $1.1 million and $1.8 million in gains on the loan sales, respectively. The Company retains the related loan servicing rights and receives servicing fees on the sold loans. Both the servicing fees and the gains on sales of loans are recorded in SBA income on the consolidated statements of operations. SBA servicing fees totaled $224,000 and $422,000 , respectively, for the three and six months ended June 30, 2015 . The Company began selling and servicing SBA loans in the fourth quarter of 2014; therefore, no sales or servicing income was recognized during the three or six months ended June 30, 2014 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 10: DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Risk Management Objective of Interest Rate Swaps and Caps The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of certain balance sheet assets and liabilities. In the normal course of business, the Company also uses derivative financial instruments to add stability to interest income or expense and to manage its exposure to movements in interest rates. The Company does not use derivatives for trading or speculative purposes and only enters into transactions that have a qualifying hedging relationship. The Company's hedging strategies involving interest rate derivatives are classified as either Fair Value Hedges or Cash Flow Hedges, depending upon 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. Risk Management Objective of Mortgage Lending Activities The Company also maintains a risk management program to manage interest rate risk and pricing risk associated with its mortgage lending activities. The risk management program includes the use of forward contracts and other derivatives that are recorded in the financial statements at fair value and are used to offset changes in value of the mortgage inventory due to changes in market interest rates. As a normal part of our operations, we enter into derivative contracts to economically hedge risks associated with overall price risk related to interest rate lock commitments ("IRLCs") and mortgage loans held-for-sale for which the fair value option has been elected. Fair value changes occur as a result of interest rate movements as well as changes in the value of the associated servicing. Derivative instruments used include forward sale commitments and IRLCs. Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. It is the Company's practice to enter into forward commitments for the future delivery of mortgage loans in order to economically hedge the effect of changes in interest rates resulting from interest rate lock commitments. The table below presents the fair values of the Company's derivative financial instruments designated as hedging instruments as well as their classifications on the consolidated statements of financial condition at the dates presented (dollars in thousands) : Derivatives Designated as Hedging Instruments Fair Value Fair Value Interest Rate Products June 30, 2015 December 31, 2014 Asset Derivatives Other Assets $ 2,322 $ 3,879 Liability Derivatives Other Liabilities $ 1,028 $ 1,666 Derivatives Designated as Hedging Instruments Fair Value Hedges The Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps, designated as fair value hedges, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments over the life of the agreements without the exchange of the underlying notional amount. The gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. At June 30, 2015 , the Company had 93 interest rate swaps with an aggregate notional amount of $160.0 million , designated as fair value hedges associated with the Company's fixed rate loan program. The table below presents the effect of the Company's derivatives in fair value hedging relationships for the periods presented (dollars in thousands) : Three Months Ended Six Months Ended June 30 June 30 Interest Rate Products Location 2015 2014 2015 2014 Amount of gain (loss) recognized in income on derivatives Noninterest income $ 1,538 $ (1,299 ) $ (133 ) $ (2,232 ) Amount of gain (loss) recognized in income on hedged items Noninterest income (1,356 ) 1,124 101 1,813 Total net gain (loss) recognized in income on fair value hedge ineffectiveness $ 182 $ (175 ) $ (32 ) $ (419 ) During the three and six months ended June 30, 2015, the Company recognized a net gain of $182,000 and a net loss of $32,000 , respectively, related to hedge ineffectiveness on the fair value swaps. The Company also recognized a net reduction in interest income of $538,000 and $ 1.1 million for the three and six months ended June 30, 2015 , respectively, related to the fair value hedges, which includes net settlements on derivatives and any amortization adjustment of the basis in the hedged items. Terminations of derivatives and related hedged items for interest rate swap agreements prior to their original maturity date resulted in the recognition of net losses of $20,000 and $ 433,000 in interest income for the three and six months ended June 30, 2015 , respectively, related to the unamortized basis in the hedged items. Cash Flow Hedges The Company uses interest rate caps as part of its interest rate risk management strategy. 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 interest rates paid on deposits, which protects the Company in a rising rate environment. The caps were purchased during the first quarter of 2013 to hedge the variable cash outflows associated with these liabilities; they originally had a five -year life and notional value of $200.0 million . The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (AOCI) and is subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of derivatives that qualify as cash flow hedges is recognized directly in earnings. No hedge ineffectiveness was recognized on the Company's cash flow hedges during the periods ended June 30, 2015 and 2014 . Amounts reported in AOCI related to derivatives are reclassified to interest expense as the interest rate cap premium is amortized over the life of the cap. During the next twelve months, $811,000 is expected to be reclassified as a decrease to net interest income.

At June 30, 2015 , the fair value of the derivative assets and liabilities not designated as hedging instruments was $4,000 and $128,000 , respectively. The income statement effect from the derivatives not designated as a hedging instrument was immaterial for the three and six months ended June 30, 2015 . Mortgage Derivatives At June 30, 2015, the Company had approximately $55.3 million of interest rate lock commitments and $95.9 million of forward commitments for the future delivery of residential mortgage loans. The net gains related to interest rate lock commitments used for risk management were $332,000 for the six months ended June 30, 2015 . The net gains for forward commitments related to these mortgage loans was $769,000 for the six months ended June 30, 2015 . The table below presents the effect of the Company's derivatives not designated as hedging instruments for the periods presented (dollars in thousands) : Three Months Ended Six Months Ended June 30 June 30 Interest Rate Products Location 2015 2014 2015 2014 Amount of gain (loss) recognized in income on interest rate swaps Noninterest income $ 61 $ (5 ) $ (3 ) $ (5 ) Amount of gain (loss) recognized in income on interest rate lock commitments Noninterest income (216 ) — 194 — Amount of loss recognized in income on forward commitments Noninterest income 132 — 132 — Total gain (loss) recognized in income on derivatives not designated as hedging instruments $ (23 ) $ (5 ) $ 323 $ (5 ) Credit-Risk-Related Contingent Features Interest Rate Swaps and Caps The Company manages credit exposure on derivative transactions by entering into a bilateral credit support agreement with each counterparty. The credit support agreements require collateralization of exposures beyond specified minimum threshold amounts. The details of these agreements, including the minimum thresholds, vary by counterparty. At June 30, 2015 , the Company posted no cash collateral under these agreements. The Company’s agreements with its derivative counterparties contain a provision where if either party defaults on any of its indebtedness, then it could also be declared in default on its derivative obligations. The agreements with derivative counterparties also include provisions that if not met, could result in the Company being declared in default. If the Company were to be declared in default, the counterparty could terminate the derivative positions and the Company and the counterparty would be required to settle their obligations under the agreements. At June 30, 2015 , the termination value of derivatives in a net liability position under these agreements was $472,000 . Although the Company did not breach any provisions at June 30, 2015 , had a breach occurred, the Company could have been required to settle obligations under the agreements at their termination values. Mortgage Derivatives The Company’s underlying risks are primarily related to interest rates and forward sales commitments entered into as part of its mortgage banking activities. Forward sales commitments are contracts for the delayed delivery or net settlement of an underlying instrument, such as a mortgage loan, in which the seller agrees to deliver on a specified future date, either a specified instrument at a specified price or yield or the net cash equivalent of an underlying instrument. These hedges are used to preserve the Company’s position relative to future sales of mortgage loans to third parties in an effort to minimize the volatility of the expected gain on sale from changes in interest rate and the associated pricing changes. Balance Sheet Offsetting Certain financial instruments, including derivatives (interest rate caps and swaps), may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The table below presents information about the Company’s financial instruments that are eligible for offset on the consolidated statements of financial condition at the dates presented (dollars in thousands) : Gross Amounts Recognized Gross Amounts Offset on the Statement of Financial Condition Net Amounts Presented on the Statement of Financial Condition Gross Amounts Not Offset on the Statement of Financial Condition Net Amount Financial Instruments Collateral Received/Posted June 30, 2015 Offsetting Derivative Assets Derivatives $ 2,326 $ — $ 2,326 $ 751 $ 1,439 $ 136 Offsetting Derivative Liabilities Derivatives $ 1,156 $ — $ 1,156 $ 751 $ — $ 405 December 31, 2014 Offsetting Derivative Assets Derivatives $ 3,879 $ — $ 3,879 $ 1,244 $ 2,529 $ 106 Offsetting Derivative Liabilities Derivatives $ 1,666 $ — $ 1,666 $ 1,244 $ — $ 422

Regulatory Matters	NOTE 11: REGULATORY MATTERS Regulatory Capital Requirements Beginning on January 1, 2015, the Company and its subsidiary banks became subject to the provisions of the Basel III final rule that governs the regulatory capital calculation, including transitional, or phase-in, provisions. The methods for calculating the risk-based capital ratios will change as the provisions of the Basel III final rule related to the numerator (capital) and denominator (risk-weighted assets) are fully phased in on January 1, 2019. The ongoing methodological changes will result in differences in the reported capital ratios from one reporting period to the next that are independent of applicable changes in the capital base, asset composition, off-balance sheet exposures or risk profile. The minimum regulatory capital ratios and ratios to be considered well-capitalized under prompt corrective action provisions at the dates indicated are presented in the table below: June 30, 2015 December 31, 2014 Capital Ratio Requirements (1) Minimum Requirement Well-capitalized (2) Minimum Requirement Well-capitalized (2) Common Equity Tier 1 Capital (CET1) 4.50% 6.50% N/A N/A Tier 1 Capital 6.00% 8.00% 4.00% 6.00% Total Capital 8.00% 10.00% 8.00% 10.00% Tier 1 Leverage 4.00% 5.00% 4.00% 5.00% (1) June 30, 2015 capital requirements are under Basel III framework.

The Company and State Bank entered into a Capital Maintenance Agreement with the FDIC on March 14, 2014. Under the terms of the Capital Maintenance Agreement, State Bank is required to maintain a leverage ratio of at least 10 % and a total risk-based capital ratio of at least 12 %. During the term of the agreement, if at any time State Bank's leverage ratio falls below 10 %, or its risk-based capital ratio falls below 12 %, the Company is required to immediately cause sufficient actions to be taken to restore State Bank's leverage and risk-based capital ratios to 10 % and 12 %, respectively. The Capital Maintenance Agreement expires on July 26, 2016. The Company and State Bank were in compliance with the Capital Maintenance Agreement at June 30, 2015 . 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 State 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 banks may distribute without prior regulatory approval. At June 30, 2015 , State Bank and First Bank had $16.3 million and $1.7 million capacity, respectively, to pay dividends to the Company without prior regulatory approval. At June 30, 2015 , the Company had $54.0 million in cash and due from bank accounts, which can be used for additional capital as needed by the subsidiary banks, payment of holding company expenses, payment of dividends to shareholders or for other corporate purposes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	NOTE 12: COMMITMENTS AND CONTINGENT LIABILITIES Commitments In order to meet the financing needs of its customers, the Company maintains financial instruments with off-balance-sheet risk in the normal course of business. These financial instruments include commitments to extend credit and standby letters of credit and involve, to varying degrees, elements of credit, interest rate and/or liquidity risk. Such financial instruments are recorded when they are funded and the related fees are generally recognized when collected. Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed maturity dates or other termination clauses with required fee payments. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The amount of collateral required, if deemed necessary upon extension of credit, is determined on a case by case basis by management through credit evaluation of the customer. Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those guarantees are issued primarily to support public and private borrowing arrangements. In order to minimize its exposure, the Company's credit policies govern the issuance of standby letters of credit. The Company's exposure to credit loss is represented by the contractual amount of those instruments. We use the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments. A summary of the Company's commitments is as follows (dollars in thousands) : June 30, 2015 December 31, 2014 Commitments to extend credit: Fixed $ 45,799 $ 21,276 Variable 505,468 405,956 Standby letters of credit: Fixed 1,289 846 Variable 7,772 4,350 Total commitments $ 560,328 $ 432,428 The fixed rate loan commitments have maturities ranging from one month to ten 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. Contingent Liabilities Mortgage loan sales agreements contain covenants that may, in limited circumstances, require the Company to repurchase or indemnify the investors for losses or costs related to the loans the Company has sold. As a result of the potential recourse provisions, the Company established a recourse liability for mortgage loans held-for-sale during the first quarter of 2015. At June 30, 2015 , the recourse liability was $651,000 . Furthermore, 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	NOTE 13: FAIR VALUE Overview 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 is generated from techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The Company evaluates fair value measurement inputs on an ongoing basis in order to determine if there is a change of sufficient significance to warrant a transfer between levels. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company's valuation process. For the six months ended June 30, 2015 and the year ended December 31, 2014 , there were no transfers between levels. Fair Value Option ASC 820 allows companies to report selected financial assets and liabilities at fair value using the fair value option. The changes in fair value are recognized in earnings and the assets and liabilities measured under this methodology are required to be displayed separately on the balance sheet. Concurrent with the First Bank acquisition, the Company made the election to record mortgage loans held-for-sale at fair value under the fair value option on a prospective basis, which allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to hedge them without the burden of complying with the requirements for hedge accounting. Mortgage loans held-for-sale were previously recorded at the lower of cost or fair value. See NOTE 1 , Basis of Presentation and Recently Adopted Accounting Standards. Financial Assets and Financial Liabilities Measured on a Recurring Basis The Company uses the following methods and assumptions in estimating the fair value of its financial assets and financial liabilities on a recurring basis: Investment Securities Available-for-Sale At June 30, 2015 , the Company's investment portfolio primarily consisted of U.S. government agency mortgage-backed securities, nonagency mortgage-backed securities, U.S. government securities, municipal securities, asset-backed securities, and corporate securities. 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. Mortgage Loans Held-for-Sale Mortgage loans held-for-sale are recorded at fair value on a recurring basis. The 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. See NOTE 1 , Basis of Presentation and Recently Adopted Accounting Standards. Interest income is recorded in interest income on the consolidated statements of operation and is based on the contractual terms of the loan. None of these loans were 90 days or more past due or on nonaccrual at June 30, 2015 . At June 30, 2015 , the aggregate fair value of the mortgage loans held-for-sale was $ 58.2 million , the contractual balance including accrued interest was $ 57.7 million and the gain recorded from the change in fair value was $ 524,000 . Derivative Financial Instruments Interest Rate Swaps and Caps 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. Mortgage Derivatives Mortgage derivatives include interest rate lock commitments to originate residential mortgage loans held-for-sale. The Company relies on an internal valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held-for-sale. The model groups the interest rate lock commitments by interest rate and term, applies an estimated pull-through rate based on historical experience, and then multiplies by quoted investor prices which were determined to be reasonably applicable to the loan commitment group based on interest rate, term, and rate lock expiration date of the loan commitment group. While there are Level 2 and 3 inputs used in the valuation model, the Company has determined that the majority of the inputs significant in the valuation of the interest rate lock commitments fall within Level 3 of the fair value hierarchy. Changes in the fair values of these derivatives are included in "mortgage banking income" on the consolidated statements of operation. The interest rate lock commitments with a positive fair value totaled $85,000 at June 30, 2015 . In addition, the interest rate lock commitments with a negative fair value totaled $217,000 at June 30, 2015 . Mortgage derivatives also include forward commitments to sell residential mortgage loans to various investors when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitment to fund loans. The Company also relies on an internal valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e., an estimate of what the Company would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available (Level 2). Changes in the fair values of these derivatives are included in "mortgage banking income" on the consolidated statements of operation. The forward commitments on interest rate lock commitments with a positive fair value totaled $ 217,000 at June 30, 2015 . Furthermore, the forward commitments on interest rate lock commitments with a negative fair value totaled $ 85,000 at June 30, 2015 . SBA Servicing Rights The Company has the rights to service a portfolio of SBA loans. The SBA servicing rights are measured at fair value when loans are sold on a servicing retained basis. The servicing rights are subsequently measured at fair value on a recurring basis utilizing Level 3 inputs. Management uses a model operated and maintained by a third party to calculate the present value of future cash flows using the third party's market-based assumptions. The future cash flows for each asset are based on the asset's unique characteristics and the third party's market-based assumptions for prepayment speeds, default and voluntary prepayments. For non-guaranteed portions of servicing assets, future cash flows are estimated using loan specific assumptions for losses and recoveries. Adjustments to fair value are recorded as a component of "other noninterest expense" on the consolidated statements of operation. Please reference NOTE 8 for the rollforward of the SBA servicing rights asset at fair value utilizing level 3 inputs. The following tables present financial assets and financial liabilities measured at fair value on a recurring basis at the dates indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands) : June 30, 2015 Quoted Market Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: U.S. Government securities $ — $ 115,298 $ — $ 115,298 States and political subdivisions — 5,824 — 5,824 Residential mortgage-backed securities — nonagency — 132,044 — 132,044 Residential mortgage-backed securities — agency — 459,762 — 459,762 Asset-backed securities — 46,571 — 46,571 Corporate securities — 55,778 — 55,778 Mortgage loans held-for-sale — 58,187 — 58,187 Mortgage derivatives (1) — 684 766 1,450 Interest rate swaps and caps — 2,326 — 2,326 SBA servicing rights — — 2,185 2,185 Total recurring assets at fair value $ — $ 876,474 $ 2,951 $ 879,425 Liabilities: Interest rate swaps and caps $ — $ 1,156 $ — $ 1,156 Mortgage derivatives (1) — 34 302 336 Total recurring liabilities at fair value $ — $ 1,190 $ 302 $ 1,492 (1) Includes mortgage related interest rate lock commitments and commitments to sell.

The fair values of impaired 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 Prior to the acquisition of First Bank, mortgage loans held-for-sale were measured on a nonrecurring basis and recorded at the lower of cost or fair value. The estimated fair value was determined using Level 2 inputs based on observable data such as the existing forward commitment terms or the current market values of similar loans. Subsequent to the acquisition of First Bank, mortgage loans held-for-sale are recorded at fair value on a recurring basis under the fair value option. The following table presents financial assets measured at fair value on a nonrecurring basis at the dates indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands) : Quoted Market Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total June 30, 2015 Impaired loans $ — $ — $ 4,485 $ 4,485 Total nonrecurring assets at fair value $ — $ — $ 4,485 $ 4,485 December 31, 2014 Impaired loans $ — $ — $ 5,167 $ 5,167 Mortgage loans held-for-sale — 3,174 — 3,174 Total nonrecurring assets at fair value $ — $ 3,174 $ 5,167 $ 8,341 Impaired loans, excluding purchased credit impaired loans, that are measured for impairment using the fair value of collateral for collateral dependent loans had principal balances of $5.2 million and $5.7 million with respective valuation allowances of $718,000 and $486,000 at June 30, 2015 and December 31, 2014 , respectively. Nonfinancial Assets Measured on a Nonrecurring Basis The Company uses the following methods and assumptions in estimating the fair values of its nonfinancial assets on a nonrecurring basis: Other Real Estate Owned The fair value of other real estate owned "OREO" is determined when the asset is transferred to foreclosed assets. Fair values of foreclosed assets held-for-sale are generally based on third party appraisals, broker price opinions or other valuations of property, resulting in a Level 3 classification. Management requires updated valuations for all other real estate owned on an annual basis. The following table presents nonfinancial assets measured at fair value on a nonrecurring basis at the dates indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value ( dollars in thousands ): Quoted Market Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total June 30, 2015 Other real estate owned $ — $ — $ 160 $ 160 Acquired other real estate owned $ — $ — $ 17,209 $ 17,209 Total other real estate owned $ — $ — $ 17,369 $ 17,369 December 31, 2014 Other real estate owned $ — $ — $ 80 $ 80 Acquired other real estate owned — — 10,859 10,859 Total other real estate owned $ — $ — $ 10,939 $ 10,939 Other real estate owned includes real property that has been acquired in satisfaction of loans receivable, organic and acquired, 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. Bank premises are transferred at the lower of carrying value or fair value, less estimated selling costs. 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. The following table is a reconciliation of the fair value measurement of other real estate owned disclosed in accordance with ASC 820 to the amount recorded on the consolidated statement of financial condition at the dates indicated (dollars in thousands) : June 30, 2015 December 31, 2014 Other real estate owned: Other real estate owned at fair value $ 160 $ 80 Estimated selling costs — (6 ) Other real estate owned $ 160 $ 74 Acquired other real estate owned: Other real estate owned at fair value $ 17,209 $ 10,859 Estimated selling costs and other adjustments (2,314 ) (2,365 ) Other real estate owned $ 14,895 $ 8,494 Unobservable Inputs for Level 3 Fair Value Measurements The following tables provide information describing the unobservable inputs used in Level 3 fair value measurements at the dates indicated (dollars in thousands) : June 30, 2015 Fair Value Valuation Technique Unobservable Inputs Range (Weighted Average) SBA servicing rights $ 2,185 Discounted cash flows Discount rate 6% - 14% (10%) Prepayment speed 4% - 9% (7%) Mortgage derivatives - asset $ 766 Pricing model Pull-through rate 82% Mortgage derivatives - liability $ 302 Pricing model Pull-through rate 82% Impaired loans - collateral dependent $ 4,485 Third party appraisal Management discount for property type and recent market volatility 0% - 50% (14%) Other real estate owned $ 160 Third party appraisal Management discount for property type and recent market volatility 0% - 0% (0%) Acquired other real estate owned $ 17,209 Third party appraisal Management discount for property type and recent market volatility 0% - 76% (38%) December 31, 2014 Fair Value Valuation Technique Unobservable Inputs Range (Weighted Average) SBA servicing rights $ 1,516 Discounted cash flows Discount rate 8% - 14% (11%) Prepayment speed 4% - 9% (7%) Impaired loans - collateral dependent $ 5,167 Third party appraisal Management discount for property type and recent market volatility 0% - 50% (9%) Other real estate owned $ 80 Third party appraisal Management discount for property type and recent market volatility 0% - 0% (0%) Acquired other real estate owned $ 10,859 Third party appraisal Management discount for property type and recent market volatility 0% - 76% (45%) Fair Value of Financial Assets and Financial Liabilities The following table includes the estimated fair value of the Company's financial assets and financial liabilities (dollars in thousands) . The methodologies for estimating the fair value of financial assets and financial liabilities measured on a recurring and nonrecurring basis are discussed above. The methodologies for estimating the fair value for other financial assets and financial liabilities are discussed below. The Company has determined the estimated fair value amounts using available market information and appropriate valuation methodologies; however, considerable judgment is required to interpret market data in order to develop the estimates of fair value. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation techniques may have a material effect on the estimated fair value amounts at June 30, 2015 and December 31, 2014 . June 30, 2015 December 31, 2014 Fair Value Hierarchy Level Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value Assets: Cash and cash equivalents Level 1 $ 201,734 $ 201,734 $ 481,158 $ 481,158 Investment securities available-for-sale Level 2 815,277 815,277 640,086 640,086 Loans held-for-sale Level 2 64,047 64,047 3,174 3,245 Loans, net Level 3 2,012,617 2,193,120 1,605,891 1,646,222 Other real estate owned Level 3 15,055 17,369 8,568 10,939 FDIC receivable for loss share agreements Level 3 — — 22,320 7,572 Interest rate swaps and caps Level 2 2,326 2,326 3,879 3,879 Mortgage derivatives Levels 2 & 3 1,450 1,450 — — SBA servicing rights Level 3 2,185 2,185 1,516 1,516 Accrued interest receivable Level 2 8,138 8,138 5,989 5,989 Federal Home Loan Bank stock Level 3 3,058 3,058 2,512 2,512 Liabilities: Deposits Level 2 $ 2,736,285 $ 2,736,679 $ 2,391,682 $ 2,391,805 Securities sold under agreements to repurchase Level 2 11,747 11,747 — — Notes payable Level 2 2,765 2,765 2,771 2,771 Interest rate swaps and caps Level 2 1,156 1,156 1,666 1,666 Mortgage derivatives Levels 2 & 3 336 336 — — Accrued interest payable Level 2 1,177 1,177 887 887 Cash and Cash Equivalents The carrying amount approximates fair value because of the short maturity of these instruments. Organic and Purchased Non-Credit Impaired Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type. The fair value of performing 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. Purchased Credit Impaired Loans Purchased credit impaired loans are recorded at fair value at the date of acquisition, exclusive of expected cash flow reimbursements from the FDIC for any loans covered by loss share agreements. 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 and lease losses. Subsequent increases to the expected cash flows results in a reversal of the provision for loan and lease losses to the extent of prior changes or a reclassification of the difference from the nonaccretable to accretable discount with a positive impact on the accretable discount. FDIC Receivable for Loss Share Agreements Prior to the Company terminating its loss share agreements with the FDIC during the second quarter of 2015, the FDIC receivable was recorded at fair value at the acquisition date. The FDIC receivable was recognized at the same time as the purchased loans, and measured on the same basis, subject to collectability or contractual limitations. The FDIC receivable was impacted by changes in estimated cash flows associated with the previously covered loans. Previous increases in the amount expected to be collected from the FDIC were recognized immediately whereas decreases were amortized over the lesser of the life of the loan or the life of the loss share agreement. Accrued Interest Receivable and Accrued Interest Payable The carrying amounts are a reasonable estimate of fair values. Federal Home Loan Bank Stock Federal Home Loan Bank stock, classified as a restricted equity security, is considered a Level 3 asset as little or no market activity exists for the security; therefore, the security's value is not market observable and is carried at original cost basis as cost approximates fair value. Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, interest-bearing deposits, and savings and money market deposits, is equal to the amount payable on demand. The fair value of time deposits is estimated by discounting the expected life. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. Securities Sold Under Agreements to Repurchase and Notes Payable The fair value of securities sold under agreements to repurchase approximates the carrying amount because of the short maturity of these borrowings. The discount rate is estimated using the rates currently offered for borrowings of similar remaining maturities. Notes payable are variable rate subordinated debt for which performance is based on the underlying notes receivable and interest rates adjust according to market value; therefore, the carrying amount approximates fair value.
