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 subsidiary, State Bank and Trust Company ("Bank" or "State 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. 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 March 31, 2016 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, 2015 . 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.

Recent Accounting and Regulatory Pronouncements [Abstract]
Recent Accounting Pronouncements	NOTE 2: RECENT ACCOUNTING PRONOUNCEMENTS Adoption of New Accounting Standards ASU 2015-16 — In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU) No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments . Under current GAAP, the acquirer is required to retrospectively adjust the provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill and is also required to revise comparative information for prior periods presented in the financial statements. The amendments in this ASU, require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in this Update also require that the acquirer record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. An entity is required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustments to the provisional amounts had been recognized as of the acquisition date. We adopted the amendments in this ASU effective January 1, 2016. The adoption of ASU No. 2015-16 did not have a material impact on our consolidated financial statements. ASC Clarification — 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 were adopted effective January 1, 2016. The adoption of these amendments did not have a material effect on our consolidated financial statements. ASU 2015-02 — 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. We adopted the amendments in this ASU effective January 1, 2016. The adoption of ASU No. 2015-02 did not have a material impact on our consolidated financial statements. Recent Accounting Pronouncements ASU 2016-09 — In March 2016, FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU simplify several aspects of share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. Excess tax benefits and tax deficiencies will be recognized as income tax expense or benefit in the income statement in the period exercise or vesting occurs. In the statement of cash flows, excess tax benefits should be classified with other income tax cash flows as an operating activity. Cash paid by an employer for tax withholding when directly withholding shares should be classified as a financing activity. An entity can make an entity-wide policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The threshold for determining whether an award is classified as equity or a liability is raised to permit withholding up to the maximum statutory tax rate in the applicable jurisdiction. The amendment in this update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted and if early adopted, all provisions must be adopted in the same period. The Company is still reviewing the impact the adoption of this guidance will have on its consolidated financial statements. ASU 2016-05 — In March 2016, FASB issued ASU No. 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships . The amendments in this Update clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The amendments in this update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted and the amendments can be adopted either on a prospective basis or a modified retrospective basis. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures. ASU 2016-02 — In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842) . The new standard requires the recognition of assets and liabilities arising from the lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend on the classification of the lease as either a finance or an operating lease. Initial costs directly attributable to negotiating and arranging the lease will be included in the asset. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. Lessees will also be required to provide additional qualitative and quantitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements and provide additional information about the nature of an organization’s leasing activities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is still reviewing the impact the adoption of this guidance will have on its consolidated financial statements. ASU 2016-01 — In January 2016, FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . The amendments in this ASU (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. The accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is prohibited except for the presentation in other comprehensive income of the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk which may be early adopted. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures. ASU 2015-14 and ASU 2014-09 — In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The ASU defers the effective date of previous ASU 2014-09 for all entities by one year. The accounting guidance is now effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and is not expected to have a significant impact on the Company's financial statements.

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 March 31, 2016 , there was no intent to sell any of the 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 are summarized in the following tables for the periods presented (dollars in thousands) : Three Months Ended March 31 Securities Available-For-Sale 2016 2015 Proceeds from sales and calls $ 22,900 $ 227,725 Gross gains on sales and calls $ 13 $ 499 Gross losses on sales and calls — (119 ) Net realized gains on sales and calls $ 13 $ 380 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 $315.0 million and $424.8 million at March 31, 2016 and December 31, 2015 , respectively, were pledged to secure public deposits and repurchase agreements.

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.

Purchased credit impaired loans modified post-acquisition are not removed from their accounting pools and accounted for as TDRs, even if those loans would otherwise be deemed TDRs. During the three months ended March 31, 2016 and 2015 , there were no organic or PNCI loans modified under the terms of a TDR. During the three months ended March 31, 2016 and 2015 , there were no organic or PNCI TDRs that subsequently defaulted within twelve months of their modification dates.

Transfers and Servicing [Abstract]
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 months ended March 31, 2016 and March 31, 2015 , the Company sold SBA loans with unpaid principal balances totaling $11.5 million and $6.1 million , and recognized $1.2 million and $680,000 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 income. SBA servicing fees totaled $277,000 and $198,000 , for the three months ended March 31, 2016 and March 31, 2015 , respectively. At March 31, 2016 and December 31, 2015 , the Company serviced SBA loans with unpaid principal balances totaling $119.6 million and $106.8 million , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 10: DERIVATIVE INSTRUMENTS & 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. Interest Rate Swaps and Caps Fair Values The table below presents the fair values of the Company's interest rate swaps and caps at the dates presented (dollars in thousands) : Asset Derivatives (1) Liability Derivatives (1) March 31, 2016 December 31, 2015 March 31, 2016 December 31, 2015 Derivatives Designated as Hedging Instruments Interest rate swaps and caps $ 369 $ 1,262 $ 4,077 $ 1,496 Derivatives Not Designated as Hedging Instruments Interest rate swaps $ — $ — $ 288 $ 174 (1) All asset derivatives are located in "Other Assets" on the consolidated statements of financial condition and all liability derivatives are located in "Other Liabilities" on the consolidated statements of financial condition. Interest Rate Swaps and Caps 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 March 31, 2016 , the Company had 99 interest rate swaps with an aggregate notional amount of $173.0 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 March 31 Interest Rate Products Location 2016 2015 Amount of loss gain recognized in income on derivatives Noninterest income $ (2,902 ) $ (1,671 ) Amount of gain recognized in income on hedged items Noninterest income 2,707 1,457 Total net loss recognized in income on fair value hedge ineffectiveness $ (195 ) $ (214 ) During the three months ended March 31, 2016 and 2015 , the Company recognized a net loss of $195,000 and $214,000 , respectively, related to hedge ineffectiveness on the fair value swaps. The Company also recognized a net reduction in interest income of $472,000 and $583,000 for the three months ended March 31, 2016 and March 31, 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 $48,000 in interest income for the three months ended March 31, 2016 and net losses of $413,000 for the three months ended March 31, 2015 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 March 31, 2016 and 2015 . 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, $1.4 million is expected to be reclassified as a decrease to net interest income. The table below presents the effect of the Company's derivatives in cash flow hedging relationships for the periods presented (dollars in thousands) : Three Months Ended March 31 Interest Rate Products Location 2016 2015 Amount of loss recognized in AOCI on derivatives (effective portion) OCI $ (682 ) $ (1,300 ) Amount of loss reclassified from AOCI into income (effective portion) Interest expense 218 101 Total loss recognized in consolidated statements of comprehensive income $ (464 ) $ (1,199 ) Interest Rate Swaps Not Designated as Hedging Instruments Interest Rate Swaps At March 31, 2016 , the Company had two interest rate swaps with an aggregate notional amount of $6.8 million not designated as fair value hedges associated with the Company's fixed rate loan program. At March 31, 2016 , the fair value of the interest rate swaps liability not designated as hedging instruments was $288,000 . The net loss recorded in the income statement for the interest rate swaps not designated as hedging instruments was $155,000 and $64,000 for the three months ended March 31, 2016 and 2015 , respectively. Credit and Collateral Risks for Interest Rate Swaps and Caps The Company manages credit exposure on interest rate swap and cap 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. Refer to Note 11 , Balance Sheet Offsetting, for more information on collateral pledged and received under these agreements. The Company’s agreements with its interest rate swap and cap 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 March 31, 2016 , the termination value of derivatives in a net liability position under these agreements was $4.2 million , for which the Company posted $2.3 million in cash collateral. Although the Company did not breach any provisions at March 31, 2016 , if a breach had occurred, the maximum amount of additional collateral the Company would have been required to post to counterparties was $1.9 million . Mortgage Derivatives 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. Mortgage Derivatives Not Designated as Hedging Instruments Mortgage derivative fair value assets and liabilities are recorded in "Other Assets" and "Other Liabilities", respectively, on the consolidated statements of financial condition. At March 31, 2016 and December 31, 2015 , the fair value of mortgage derivative assets was $1.4 million and $869,000 and the fair value of mortgage derivative liabilities was $834,000 and $505,000 , respectively. At March 31, 2016 and December 31, 2015 , the Company had approximately $74.6 million and $47.3 million of interest rate lock commitments and $107.7 million and $85.9 million of forward commitments for the future delivery of residential mortgage loans, respectively. The net gain related to interest rate lock commitments was $571,000 and $690,000 for the three months ended March 31, 2016 and 2015 , respectively. The net loss for forward commitments related to these mortgage loans was $342,000 and $326,000 for the three months ended March 31, 2016 and 2015 , respectively. The table below presents the effect of the Company's mortgage derivatives not designated as hedging instruments for the periods presented (dollars in thousands) : Three Months Ended March 31 Interest Rate Products Location 2016 2015 Amount of gain recognized in income on interest rate lock commitments Noninterest income $ 571 $ 690 Amount of loss recognized in income on forward commitments Noninterest income (342 ) (326 ) Total gain recognized in income on derivatives not designated as hedging instruments $ 229 $ 364 Credit and Collateral Risks for Mortgage Lending Activities 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.

Offsetting [Abstract]
Balance Sheet Offsetting and Repurchase Agreements	NOTE 11: BALANCE SHEET OFFSETTING AND REPURCHASE AGREEMENTS Balance Sheet Offsetting Certain financial instruments, including repurchase agreements and derivatives (interest rate swaps and caps), may be eligible for offset in the consolidated statements of financial condition and/or subject to master netting arrangements or similar agreements; 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 in 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 (1) March 31, 2016 Offsetting Assets Interest rate swaps and caps $ 369 $ — $ 369 $ (369 ) $ — $ — Offsetting Liabilities Interest rate swaps and caps $ 4,365 $ — $ 4,365 $ (369 ) $ (2,330 ) $ 1,666 Repurchase agreements 33,503 — 33,503 — (33,503 ) — Total liabilities $ 37,868 $ — $ 37,868 $ (369 ) $ (35,833 ) $ 1,666 December 31, 2015 Offsetting Assets Interest rate swaps and caps $ 1,262 $ — $ 1,262 $ (883 ) $ (150 ) $ 229 Offsetting Liabilities Interest rate swaps and caps $ 1,670 $ — $ 1,670 $ (883 ) $ (269 ) $ 518 Repurchase agreements 32,179 — 32,179 — (32,179 ) — Total liabilities $ 33,849 $ — $ 33,849 $ (883 ) $ (32,448 ) $ 518 (1) The application of collateral cannot reduce the net amount below zero; therefore, excess collateral received/posted is not reflected in this table. All positions are fully collateralized. Repurchase Agreements The Company utilizes securities sold under repurchase agreements to facilitate the needs of our customers. Securities sold under repurchase agreements consist of balances in the transaction accounts of commercial customers swept nightly to an overnight investment account and are collateralized with investment securities having a market value no less than the balance borrowed. The investment securities pledged are subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below the balance of the repurchase agreements on a daily basis and may be required to provide additional collateral. Securities pledged as collateral are maintained with our safekeeping agent. At March 31, 2016 and December 31, 2015 , securities sold under repurchase agreements were $33.5 million and $32.2 million , respectively, all of which mature on an overnight and continuous basis. At both March 31, 2016 and December 31, 2015 , investment securities pledged for the outstanding repurchase agreements consisted of U.S. government sponsored agency mortgage-backed securities.

Banking and Thrift [Abstract]
Regulatory Matters	NOTE 12: REGULATORY MATTERS Regulatory Capital Requirements Beginning on January 1, 2015, the Company and its subsidiary bank 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. Beginning on January 1, 2016, the Company and its subsidiary bank must maintain a capital conservation buffer to avoid restrictions on capital distributions or discretionary bonus payments. This buffer must consist solely of Common Equity Tier 1 Capital, but the buffer applies to all three measurements (Common Equity Tier 1, Tier 1 capital and total capital) in addition to the minimum risk-based capital requirements. The capital conservation buffer required for 2016 is common equity equal to .625% of risk-weighted assets and will increase by .625% per year until reaching 2.5% beginning January 1, 2019. The minimum regulatory capital ratios and ratios to be considered well-capitalized under prompt corrective action provisions at both March 31, 2016 and December 31, 2015 are presented in the table below: Capital Ratio Requirements Minimum Requirement Well-capitalized (1) Common Equity Tier 1 Capital (CET1) 4.50% 6.50% Tier 1 Capital 6.00% 8.00% Total Capital 8.00% 10.00% Tier 1 Leverage 4.00% 5.00% (1) The prompt corrective action provisions are only applicable at the bank level. At March 31, 2016 and December 31, 2015 , the Company and State Bank exceeded all regulatory capital adequacy requirements to which they were subject.

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 March 31, 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 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 March 31, 2016 , State Bank had capacity to pay $17.0 million in dividends to the Company without prior regulatory approval. At March 31, 2016 , the Company had $49.6 million in cash and due from bank accounts, which can be used for additional capital as needed by State Bank, 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 13: 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. The Company uses 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) : March 31, 2016 December 31, 2015 Commitments to extend credit: Fixed $ 26,501 $ 28,744 Variable 534,082 502,538 Letters of credit: Fixed 2,762 1,907 Variable 4,276 4,925 Total commitments $ 567,621 $ 538,114 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 maintains a recourse liability for mortgage loans sold to investors. At March 31, 2016 , the recourse liability was $381,000 . 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

Fair Value Disclosures [Abstract]
Fair Value	NOTE 14: 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 three months ended March 31, 2016 and the year ended December 31, 2015 , 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. The Company made the election to record mortgage loans held-for-sale at fair value under the fair value option, 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. 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 March 31, 2016 , 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. Interest income is recorded in interest income on the consolidated statements of income 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 March 31, 2016 . At March 31, 2016 , the aggregate fair value of the mortgage loans held-for-sale was $47.9 million and the contractual balance including accrued interest was $46.4 million , with a fair value mark totaling $1.4 million . The gain recognized for the change in fair value of the mortgage loans held-for-sale, included in "mortgage banking income" on the consolidated statements of income, was $455,000 for the three months ended March 31, 2016 . 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 income. 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 income. 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 "SBA income" on the consolidated statements of income. 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) : March 31, 2016 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 $ — $ 94,791 $ — $ 94,791 States and political subdivisions — 1,797 — 1,797 Residential mortgage-backed securities — nonagency — 162,167 — 162,167 Residential mortgage-backed securities — agency — 513,135 — 513,135 Corporate securities — 77,686 — 77,686 Mortgage loans held-for-sale — 47,854 — 47,854 Mortgage derivatives — 77 1,350 1,427 Interest rate swaps and caps — 369 — 369 SBA servicing rights — — 2,882 2,882 Total recurring assets at fair value $ — $ 897,876 $ 4,232 $ 902,108 Liabilities: Interest rate swaps and caps $ — $ 4,365 $ — $ 4,365 Mortgage derivatives — 199 635 834 Total recurring liabilities at fair value $ — $ 4,564 $ 635 $ 5,199 December 31, 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 $ — $ 103,272 $ — $ 103,272 States and political subdivisions — 1,813 — 1,813 Residential mortgage-backed securities — nonagency — 150,702 — 150,702 Residential mortgage-backed securities — agency — 503,688 — 503,688 Asset-backed securities — 46,245 — 46,245 Corporate securities — 81,985 — 81,985 Mortgage loans held for sale — 48,803 — 48,803 Mortgage derivatives — 218 651 869 Interest rate swaps and caps — 1,262 — 1,262 SBA servicing rights — — 2,626 2,626 Total recurring assets at fair value $ — $ 937,988 $ 3,277 $ 941,265 Liabilities: Derivative financial instruments $ — $ 1,670 $ — $ 1,670 Mortgage derivatives — 144 361 505 Total recurring liabilities at fair value $ — $ 1,814 $ 361 $ 2,175 Three Months Ended March 31 2016 Mortgage Derivatives Other Assets Other Liabilities Balance, beginning of period $ 651 $ 361 Acquired — — Issuances (1) 1,051 627 Settlements and closed loans (1) (352 ) (353 ) Balance, end of period $ 1,350 $ 635 Three Months Ended March 31 2015 Mortgage Derivatives Other Assets Other Liabilities Balance, beginning of period $ — $ — Acquired 272 135 Issuances (1) 785 351 Settlements and closed loans (1) (131 ) (131 ) Balance, end of period $ 926 $ 355 (1) Total gain on the change in fair value, recorded as a component of "mortgage banking income" on the consolidated statements of income, was $425,000 and $434,000 for the three months ended March 31, 2016 and March 31, 2015 , respectively. Financial Assets Measured on a Nonrecurring Basis The Company uses the following methods and assumptions in estimating the fair value of its financial assets on a nonrecurring basis: Impaired Loans Loans, excluding purchased credit impaired loans, are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The fair values of impaired 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. 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 March 31, 2016 Impaired loans $ — $ — $ 8,641 $ 8,641 Total nonrecurring assets at fair value $ — $ — $ 8,641 $ 8,641 December 31, 2015 Impaired loans $ — $ — $ 5,941 $ 5,941 Total nonrecurring assets at fair value $ — $ — $ 5,941 $ 5,941 Impaired loans, excluding purchased credit impaired loans, that are measured for impairment using the fair value of collateral for collateral dependent loans had recorded investments of $12.0 million and $7.0 million with respective valuation allowances of $3.4 million and $1.0 million at March 31, 2016 and December 31, 2015 , 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 Other real estate owned ("OREO") consists of real estate acquired through foreclosure or a deed in lieu of foreclosure in satisfaction of a loan, OREO acquired in a business acquisition, and banking premises no longer used for a specific business purpose. Real estate obtained 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 with any excess in loan balance charged against the allowance for loan and lease losses. OREO acquired in a business acquisition is recorded at fair value on Day 1 of the acquisition. Banking premises no longer used for a specific business purpose is transferred into OREO at the lower of its carrying value or fair value less estimated costs to sell with any excess in the carrying value charged to noninterest expense. For all fair value estimates of the real estate properties, management considers a number of factors such as appraised values, estimated selling prices, and current market conditions, resulting in a Level 3 classification. Management periodically reviews the carrying value of OREO for impairment and adjusts the values as appropriate through noninterest expense. 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 March 31, 2016 Other real estate owned $ — $ — $ 13,998 $ 13,998 December 31, 2015 Other real estate owned $ — $ — $ 12,110 $ 12,110 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) : March 31, 2016 December 31, 2015 Other real estate owned: Other real estate owned at fair value $ 13,998 $ 12,110 Estimated selling costs and other adjustments (2,408 ) (1,580 ) Other real estate owned $ 11,590 $ 10,530 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) : March 31, 2016 Fair Value Valuation Technique Unobservable Inputs Range (Weighted Average) SBA servicing rights $ 2,882 Discounted cash flows Discount rate 9% - 18% (12%) Prepayment speed 4% - 11% (8%) Mortgage derivatives - asset $ 1,350 Pricing model Pull-through rate 83% Mortgage derivatives - liability $ 635 Pricing model Pull-through rate 83% Impaired loans - collateral dependent $ 8,641 Third party appraisal Management discount for property type and recent market volatility 0% - 50% (30%) Other real estate owned $ 13,998 Third party appraisal Management discount for property type and recent market volatility 0% - 68% (16%) December 31, 2015 Fair Value Valuation Technique Unobservable Inputs Range (Weighted Average) SBA servicing rights $ 2,626 Discounted cash flows Discount rate 9% - 17% (12%) Prepayment speed 4% - 10% (8%) Mortgage derivatives - asset $ 651 Pricing model Pull-through rate 81% Mortgage derivatives - liability $ 361 Pricing model Pull-through rate 81% Impaired loans - collateral dependent $ 5,941 Third party appraisal Management discount for property type and recent market volatility 0% - 50% (15%) Other real estate owned $ 12,110 Third party appraisal Management discount for property type and recent market volatility 0% - 75% (33%) 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 March 31, 2016 and December 31, 2015 .

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. 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. 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 Repurchase Agreements and Notes Payable The fair value of securities sold under repurchase agreements 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.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 15: EARNINGS PER SHARE The Company has granted stock compensation awards with nonforfeitable dividend rights which are considered participating securities. As such, earnings per share is calculated using the two-class method. Basic earnings per share is calculated by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period which excludes the participating securities. Diluted earnings per share includes the dilutive effect of additional potential common shares from stock compensation awards and warrants. Earnings per share have been computed based on the following weighted average number of common shares outstanding (dollars in thousands, except per share data) : Three Months Ended March 31 2016 2015 Numerator: Net income per consolidated statements of income $ 10,838 $ 9,204 Net income allocated to participating securities (285 ) (209 ) Net income allocated to common stock $ 10,553 $ 8,995 Basic earnings per share computation: Net income allocated to common stock $ 10,553 $ 8,995 Weighted average common shares outstanding, including shares considered participating securities 37,065,427 34,373,665 Less: Average participating securities (973,158 ) (779,978 ) Weighted average shares 36,092,269 33,593,687 Basic earnings per share $ .29 $ .27 Diluted earnings per share computation: Net income allocated to common stock $ 10,553 $ 8,995 Weighted average common shares outstanding for basic earnings per share 36,092,269 33,593,687 Weighted average dilutive grants 95,393 1,268,637 Weighted average shares and dilutive potential common shares 36,187,662 34,862,324 Diluted earnings per share $ .29 $ .26 In connection with the preparation of the consolidated financial statements for the three and nine month periods ended September 30, 2015, an error in the computation and disclosure of diluted earnings per share was identified. The error resulted from the inclusion of restricted stock as outstanding in the basic weighted average common shares outstanding, as well as the dilutive effect of the restricted stock in the calculation of weighted average diluted shares outstanding in prior periods. The Company evaluated the materiality of the error in accordance with SEC Staff Accounting Bulletin No. 99, Materiality , SEC Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements , and Accounting Standards Codification 250, Accounting for Changes and Error Corrections, and concluded the error was immaterial to all prior periods impacted. While the adjustments were immaterial, the Company has elected to revise its previously reported diluted earnings per share. Earnings per share increased $.01 on a diluted basis for the three months ended March 31, 2015 .
