Accounting Policies [Abstract]
Nature of Business and Summary of Significant Accounting Policies	NOTE 1: NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements of State Bank Financial Corporation and Subsidiary (the "Company") include the financial statements of State Bank Financial Corporation and its wholly-owned subsidiary, State Bank and Trust Company (the "Bank" or "State Bank"). All intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications of prior year amounts have been made to conform with the current year presentations. These reclassifications had no impact on prior years' net income, as previously reported. State Bank and Trust Company was organized as a Georgia-state chartered bank, which opened October 4, 2005 in Pinehurst, Georgia. The Bank is primarily regulated by the FDIC and undergoes periodic examinations by this regulatory authority. On July 24, 2009, State Bank and Trust Company closed on investment agreements under which new investors infused $292.1 million , gross (before expenses), of additional capital into the Bank, which resulted in a successor entity. This significant recapitalization resulted in a change of control and a new basis of accounting was applied. At the annual shareholders' meeting held March 11, 2010, approval was granted through proxy vote for the formation of a bank holding company. The required regulatory approval was obtained in July 2010 and the holding company reorganization was completed July 23, 2010. Between July 24, 2009 and December 31, 2015 , the Company successfully completed 14 bank acquisitions totaling $4.6 billion in assets and $4.1 billion in deposits. The acquisitions include the Company's merger with Georgia-Carolina Bancshares, Inc., the holding company for First Bank of Georgia ("First Bank"), which closed on January 1, 2015. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America and to prevailing practices within the financial institutions industry. The following is a summary of the significant accounting policies that the Company follows in presenting its consolidated financial statements. Nature of Business State Bank Financial Corporation is a bank holding company whose primary business is conducted through 26 branch offices of State Bank and Trust Company, its wholly-owned banking subsidiary. Through the Bank, the Company operates a full service banking business and offers a broad range of commercial and retail banking products to its customers throughout Middle Georgia, Metropolitan Atlanta, and Augusta, Georgia. The Company also operates seven mortgage origination offices. The Company is subject to regulations of certain federal and state agencies and is periodically examined by those regulatory agencies. Basis of Presentation In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenue and expenses for the period. Actual results could differ significantly from those estimates. Significant estimates include the allowance for loan and lease losses, the valuation of other real estate owned, the amount and timing of expected cash flows from purchased credit impaired loans, the fair value of investment securities and other financial instruments, and the valuation of goodwill. A substantial portion of the Company's loans are secured by real estate located in its market area. Accordingly, the ultimate collectability of a substantial portion of the Company's loan portfolio is susceptible to changes in the real estate market conditions. As defined by authoritative guidance, segment disclosures require reporting information about a company's operating segments using a “management approach.” Reportable segments are identified as those revenue-producing components for which separate financial information is produced internally and which are subject to evaluation by the chief operating decision maker in deciding how to allocate resources to segments. The Company operates as one reportable segment. Cash and Cash Equivalents Cash and cash equivalents, as presented in the consolidated financial statements, includes cash on hand, cash items in process of collection and interest-bearing deposits with other financial institutions with maturities less than 90 days. Investments Management determines the appropriate classifications of investment securities at the time of purchase and reevaluates such designation as needed. At December 31, 2015 and 2014 , the Company classified all of its investment securities as available-for-sale. Investments available-for-sale are reported at fair value, as determined by independent quotations. Purchase premiums and discounts on investment securities are amortized and accreted to interest income using the effective interest rate method over the remaining lives of the securities, taking into consideration assumed prepayment patterns. Realized gains and losses are derived using the specific identification method for determining the cost of securities sold and are recognized on the trade date. Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. In connection with the assessment for other than temporary impairment of investment securities, management obtains fair value estimates by independent quotations, assesses current credit ratings and related trends, reviews relevant delinquency and default information, assesses expected cash flows and coverage ratios, assesses the relative strength of credit support from less senior tranches of the securities, reviews average credit score data of underlying mortgages, and assesses other current data. The severity and duration of impairment and the likelihood of potential recovery of impairment is considered along with the intent and ability to hold any impaired security to maturity or recovery of carrying value. Unrealized holding losses, other than those determined to be other than temporary, and unrealized holding gains are excluded from net income and are reported, net of tax, in other comprehensive income and in accumulated other comprehensive income (loss), a separate component of shareholders' equity. A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for that security. At December 31, 2015 and 2014 , the Company did not have any securities with other than temporary impairment. Investment in stock of the Federal Home Loan Bank ("FHLB") is required of every federally insured financial institution which utilizes the FHLB's services. The investment in FHLB stock is included in "other assets" at its original cost basis, as cost approximates fair value since there is no readily determinable market value for such investments. Organic Loans Organic loans, defined as loans not purchased in the acquisition of an institution or credit impaired portfolio, are loans management has the intent and ability to hold for the foreseeable future, until maturity, or until payoff. Organic loans are reported at their principal amounts outstanding, net of unearned income, net of deferred loan fees and origination costs, net of unamortized premiums or discounts on purchased participation loans, and net of the allowance for loan and lease losses. Interest income is recognized using the simple interest method on the daily balance of the principal amount outstanding. Unearned income, primarily arising from deferred loan fees net of certain origination costs, is amortized over the lives of the underlying loans using the effective interest rate method. Past due status is based on the contractual terms of the loan agreement. Generally, the accrual of interest income is discontinued and loans are placed on nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal. Interest previously accrued but not collected is reversed against current period interest income when such loans are placed on nonaccrual status. Interest on nonaccrual loans when ultimately collected is recorded as a principal reduction. Nonaccrual loans are returned to accrual status when all principal and interest amounts contractually due are brought current. In addition, the future payments must be reasonably assured along with a period of at least six months of repayment performance by the borrower depending on the contractual payment terms. When it has been determined that a loan cannot be collected in whole or in part, then the uncollectible portion is charged-off. The Company considers an organic loan impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Additionally, loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings ("TDRs") and are included in impaired loans. The Company's policy requires that all impaired loans with contractual balances of $500,000 and greater be individually reviewed for impairment. Loans are reviewed for impairment based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or the loan's observable market price, or the fair value of the collateral less disposal costs, as applicable, if the loan is collateral dependent. The Company's policy requires that large pools of smaller balance homogeneous loans, such as consumer, residential and installment loans, be collectively evaluated for impairment by the Company. Impairment losses are included in the allowance for loan and lease losses through a provision charge to earnings. All loans considered impaired are placed on nonaccrual status in accordance with policy. The interest portion of cash receipts on impaired loans are recorded as income when received unless full recovery of principal is in doubt whereby cash received is recorded as a reduction to the Company's recorded investment in the loan. All organic impaired loans are reviewed at least quarterly. Reviews may be performed more frequently if material information is available before the next scheduled quarterly review. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. The discounts may include the following: length of time to market and sell the property, as well as expected maintenance costs, insurance and taxes and real estate commissions on sale. Purchased Loans Purchased non-credit impaired loans ("PNCI loans") Loans acquired without evidence of deterioration in credit quality since origination, referred to as purchased non-credit impaired loans, are initially recorded at estimated fair value on the acquisition date. Premiums and discounts created when the loans are recorded at their estimated fair values at acquisition are amortized or accreted over the remaining term of the loan as an adjustment to the related loan's yield. The Company accounts for performing loans acquired in business combinations using the contractual cash flows method whereby premiums and discounts are recognized using the interest method. There is no allowance for loan and lease losses established at the acquisition date for purchased loans. Following the acquisition of these loans, the policies regarding nonaccrual and impaired loan status is consistent with that described above for organic loans. A provision for loan losses is recorded should there be deterioration in these loans subsequent to the acquisition. Purchased credit impaired loans ("PCI loans") Purchased credit impaired loans, defined as acquired loans, which at acquisition, management determined it was probable that the Company would be unable to collect all contractual principal and interest payments due, 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, if appropriate, an accretable discount. The nonaccretable discount, which is excluded from the carrying amount of acquired loans, is the difference between the contractually required payments and the cash flows expected to be collected at acquisition. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan when there is reasonable expectation about the amount and timing of such cash flows. The difference between actual prepayments and expected prepayments does not affect the nonaccretable discount. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows results in either a reversal of the provision for loan losses or a reclassification of the difference from nonaccretable to accretable, both of which have a positive impact on the accretable discount. All loans acquired in failed bank transactions are considered to have evidence of credit deterioration, as limited due diligence is afforded which does not allow a sufficient detailed review to classify the acquired loans into credit deterioration and performing categories. At the time of acquisition, purchased credit impaired loans are either accounted for as specifically-reviewed or as part of a loan pool. Loan pools are created by grouping loans with similar risk characteristics, the intent being to create homogeneous pools. Loans are grouped into pools based on a combination of various factors including product type, cohort, risk classification and term. Loans remain in the assigned pool until the individual pools have resolved. Gains and losses on individual loans within pools are deferred and retained in the pools until the pool closes, which is either when all the loans are resolved or the pool’s aggregate recorded investment reaches zero. Allowance for Loan and Lease Losses ("ALLL") The ALLL represents the amount considered adequate by management to absorb losses inherent in the loan portfolio at the balance sheet date. The ALLL is adjusted through provisions for loan losses charged or credited to operations. The provisions are generated through loss analyses performed on organic loans, estimated additional losses arising on PNCI loans subsequent to acquisition and impairment recognized as a result of decreased expected cash flows on PCI loans due to further credit deterioration since the previous quarterly cash flow re-estimation. The ALLL consists of both specific and general components. Individual loans are charged off against the ALLL when management determines them to be uncollectible. Subsequent recoveries, if any, of loans previously charged-off are credited to the ALLL. All known and inherent losses that are both probable and reasonable to estimate are recorded. While management utilizes available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance. Such agencies may require adjustments to the ALLL based on their judgment about information available at the time of their examination. The Company assesses the adequacy of the ALLL quarterly with respect to organic and purchased loans. The assessment begins with a standard evaluation and analysis of the loan portfolio. All loans are consistently graded and monitored for changes in credit risk and possible deterioration in the borrower’s ability to repay the contractual amounts due under the loan agreements. Allowance for loan and lease losses for organic loans: The ALLL for organic loans consists of two components: (1) a specific amount against identified credit exposures where it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreements; and (2) a general amount based upon historical losses that are then adjusted for qualitative factors representative of various economic indicators and risk characteristics of the loan portfolio. Management establishes the specific amount by examining impaired loans. The majority of the Company's impaired loans are collateral dependent; therefore, nearly all of the specific allowances are calculated based on the fair value of the collateral less disposal costs, if applicable. Management establishes the general amount by reviewing the remaining loan portfolio (excluding those impaired loans discussed above) and incorporating allocations based on historical losses. The calculation of the general amount is subjected to qualitative factors that are somewhat subjective. The qualitative testing attempts to correlate the historical loss rates with current economic factors and current risks in the portfolio. The qualitative factors consist of but are not limited to: (1) economic factors including changes in the local or national economy; (2) the depth of experience in lending staff; (3) asset quality trends; and (4) seasoning and growth rate of the portfolio segments. After assessing the applicable factors, the remaining amount is evaluated based on management's experience and the level of the organic ALLL is compared with historical trends and peer information as a reasonableness test. Allowance for loan and lease losses for purchased loans: Purchased loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan and lease losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for purchased loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, default rates, loss severity, collateral values, discount rates, payment speeds, prepayment risk and liquidity risk. The Company maintains an ALLL on purchased loans based on credit deterioration subsequent to the acquisition date. For purchased credit impaired loans accounted for under ASC 310-30, management establishes an allowance for credit deterioration subsequent to the date of acquisition by quarterly re-estimating expected cash flows with any decline in expected cash flows recorded as impairment in the provision for loan losses. Impairment is measured as the excess of the recorded investment in a loan over the present value of expected future cash flows discounted at the pre-impairment accounting yield of the loan. For any increases in cash flows expected to be collected, the Company first reverses only previously recorded ALLL, then adjusts the amount of accretable yield recognized on a prospective basis over the loan’s remaining life. For purchased loans that are not deemed impaired at acquisition, also referred to as purchased non-credit impaired loans, credit discounts representing the principal losses expected over the life of the loan are a component of the initial fair value and the discount is accreted to interest income over the life of the asset. Subsequent to the purchase date, the method used to evaluate the sufficiency of the credit discount is similar to originated loans, and if necessary, additional reserves are recognized in the allowance for loan and lease losses. Loans Held-for-Sale 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. Mortgage Loans Held-for-Sale Concurrent with the First Bank acquisition in January 2015, the Company made the election to record mortgage loans held-for-sale at fair value under the fair value option on a prospective basis. Mortgage loans held-for-sale were previously recorded at the lower of cost or fair value. 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. Net origination fees and costs are recognized in earnings at the time of origination for residential mortgage loans held-for-sale. Gains and losses on mortgage loan sales 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, are classified on the consolidated statements of income as noninterest income - mortgage banking income. The loan sales agreements 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. SBA Loans Held-for-Sale SBA loans held-for-sale are recoded 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 part of the basis of the loan and are included in the calculation of realized gains and losses upon sale. Gains and losses are classified on the consolidated statements of income as noninterest income - SBA income. All SBA loan sales are executed on a servicing retained basis - refer to Small Business Administration ("SBA") Servicing Rights below for more information . Other Real Estate Owned ("OREO") Other real estate owned consists of real property (a) acquired through mergers and acquisitions, (b) acquired through foreclosure in satisfaction of loans receivable, and (c) banking premises formerly, but no longer, used for a specific business purpose. Other real estate is distinguished between organic, purchased non-credit impaired, or purchased credit impaired, consistent with the categories, respectively, at time of transfer. Real property acquired through mergers and acquisitions are recorded at fair value on Day 1 of the acquisition. Real estate acquired through foreclosure of loans, consisting of properties obtained through foreclosure proceedings or acceptance of a deed in lieu of foreclosure, is reported on an individual asset basis at the lower of cost or fair value, less costs to sell with any excess in loan balance charged against the allowance for loan and lease losses. Banking premises no longer used for a specific business purposes is transferred into OREO at the lower of its carrying value or fair value, less estimated costs to sell with any excess in carrying value charged to noninterest expense. For all fair value estimates of the real estate properties, fair value is determined on the basis of current appraisals, comparable sales, current market conditions, and other estimates of value obtained principally from independent sources. Management periodically reviews the carrying value of OREO for subsequent declines in fair value and adjusts the values as appropriate through noninterest expense. Gains or losses recognized on the disposition of the properties are recorded on the consolidated statements of income as "loan collection costs and OREO activity". Costs of improvements to real estate are capitalized, while costs associated with holding the real estate are charged to income. Prior to termination of the Company's loss share agreements with the FDIC in May 2015, OREO formerly covered under the agreements were reported exclusive of expected reimbursement cash flows from the FDIC. Subsequent adjustments to the estimated recoverable value of the other real estate resulted in a reduction of other real estate and a charge to other expense. The FDIC receivable was increased for the estimated amount to be reimbursed, with a corresponding offsetting amount recorded to other expense. Costs associated with holding the formerly covered other real estate were charged to income, net of any expected reimbursements from the FDIC relating to previously covered external expenses. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation, which is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of the assets range from 10 to 25 years for buildings and improvements and 3 to 15 years for furniture, fixtures, and equipment. Costs of improvements are capitalized and depreciated, while operating expenses are charged to current earnings. Goodwill and Other Intangibles, Net Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangibles deemed to have an indefinite life are not amortized but instead are subject to review for impairment annually, or more frequently if deemed necessary. Also in connection with business combinations, the Company records core deposit intangibles, representing the value of the acquired core deposit base, and other identifiable intangible assets. Core deposit intangibles and other identifiable intangible assets are amortized on a straight-line basis over their estimated useful lives ranging up to 10 years. Small Business Administration ("SBA") Servicing Rights All sales of SBA loans, consisting of the guaranteed portion, are executed on a servicing retained basis. The standard sale structure under the SBA Secondary Participation Guaranty Agreement provides for the Company to retain a portion of the cash flow from the interest payment received on the loan. This cash flow is commonly known as a servicing spread. For any guaranteed loans sold at a premium, SBA regulations require the lender to keep a minimum 100 basis points in servicing spread which includes a minimum service fee of 40 basis points and a minimum premium protection fee of 60 basis points. The servicing spread is recognized as a servicing asset to the extent the spread exceeds adequate compensation for the servicing function. The fair value of the servicing asset is measured on a recurring basis at the present value of future cash flows using market-based discount assumptions. The future cash flows for each asset are based on their unique characteristics and 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. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. FDIC Receivable for Loss Share Agreements and Clawback Liability On May 21, 2015, State Bank entered into an agreement with the FDIC to terminate loss share coverage on all 12 FDIC-assisted acquisitions. The termination resulted in the elimination of both the FDIC receivable for loss share agreements and the associated clawback liability. The FDIC receivable for loss share agreements was measured separately from the related formerly covered assets and was not contractually embedded in the assets or transferable if the assets were sold. The fair value of the FDIC receivable was estimated at acquisition using projected cash flows related to loss share agreements based on the expected reimbursements for losses using the applicable loss share percentages. The cash flows were discounted to reflect the estimated timing of the receipt of the loss share reimbursements from the FDIC. The FDIC receivable was reviewed and updated prospectively as loss estimates related to formerly covered assets changed and as reimbursements were received or were expected to be received from the FDIC. Improvements in the credit quality or cash flows of formerly covered loans (reflected as an adjustment to yield and accreted into income over the remaining life of the covered loans) decreased the basis of the FDIC receivable, with decreases being amortized into income over the remaining life of the loan or life of the loss share agreement, whichever was shorter. Any applicable true-up payments owed the FDIC for loss share agreements with clawback provisions were discounted to reflect the estimated timing of the payment and such amount was reported as a liability in "other liabilities" on the consolidated statements of financial condition. In addition, recoveries of FDIC-indemnified losses on loans were reimbursed to the FDIC during the coverage period under the loss share agreements. Derivative Instruments and Hedging Activities Interest Rate Swaps and Caps The Company enters into derivative financial instruments to manage interest rate risk, facilitate asset/liability management strategies and manage other exposures. These instruments may include interest rate swaps and interest rate caps and floors. All derivative financial instruments are recognized on the consolidated statements of financial condition as other assets or other liabilities, as applicable, at estimated fair value. The Company enters into master netting agreements with counterparties and/or requires collateral to cover exposures. In most cases, counterparties post at a zero threshold regardless of rating. Interest rate swaps are agreements to exchange interest payments based upon notional amounts. Interest rate swaps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform. Option contracts involve rights to buy or sell financial instruments on a specified date or over a period at a specified price. These rights do not have to be exercised. Some option contracts such as interest rate caps, involve the exchange of cash based on changes in specified indices. Interest rate caps are contracts to hedge interest rate increases based on a notional amount. Interest rate caps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform. Derivative financial instruments are designated, based on the exposure being hedged, as either fair value or cash flow hedges. Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Under the fair value hedging model, gains or losses attributable to the change in fair value of the derivative instrument, as well as the gains and losses attributable to the change in fair value of the hedged item, are recognized in other noninterest income in the period in which the change in fair value occurs. Hedge ineffectiveness is recognized as other noninterest income to the extent the changes in fair value of the derivative do not offset the changes in fair value of the hedged item. The corresponding adjustment to the hedged asset or liability is included in the basis of the hedged item, while the corresponding change in the fair value of the derivative instrument is recorded as an adjustmen

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 December 31, 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 (dollars in thousands) : December 31 2015 2014 2013 Proceeds from sales and calls $ 364,023 $ 112,944 $ 28,636 Gross gains on securities available-for-sale $ 618 $ 266 $ 1,081 Gross losses on securities available-for-sale (264 ) (20 ) — Net realized gains on securities available-for-sale $ 354 $ 246 $ 1,081 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 $424.8 million and $283.4 million at December 31, 2015 and 2014 , respectively, were pledged to secure public deposits and repurchase agreements.

Subsequent decreases in the amount of cash expected to be collected from the borrower results in a provision for loan and lease losses and an increase in the allowance for loan and lease losses. Subsequent increases in the amount of cash expected to be collected from the borrower results in the reversal of any previously-recorded provision for loan and lease losses and related allowance for loan and lease losses, and then as a prospective increase in the accretable discount on the purchased credit impaired loans. The accretable discount is accreted into interest income over the estimated life of the related loan on a level yield basis. Changes in the value of the accretable discount are presented in the following table for the periods presented (dollars in thousands) : December 31 Changes in Accretable Discount 2015 2014 2013 Balance, beginning of year $ 120,061 $ 185,024 $ 172,804 Additions from acquisitions 317 7,351 — Accretion (49,830 ) (78,857 ) (122,466 ) Transfers to accretable discounts and exit events, net 15,552 6,543 134,686 Balance, end of year $ 86,100 $ 120,061 $ 185,024 The accretable discount changes over time as the purchased credit impaired loan portfolios season. The change in the accretable discount is a result of the Company's review and re-estimation of loss assumptions and expected cash flows on acquired loans. At December 31, 2015 and 2014 , in accordance with Company policy, there were no loans to executive officers, directors and/or their affiliates.

Management has identified the most significant risks associated with segments and classes as described below. While the list is not exhaustive, it provides a description of the risks that management has determined are the most significant. Real Estate Loans Loans secured by real estate are the principal component of our loan portfolio. Real estate loans are subject to the same general risks as other loans and are particularly sensitive to fluctuations in the value of real estate. Increases in interest rates, decline in occupancy rates, fluctuations in the value of real estate, as well as other factors arising after a loan has been made, could negatively affect a borrower's cash flow, creditworthiness and ability to repay the loan. When we make new real estate loans, we typically obtain a security interest in the real estate, as well as other available credit enhancements, to increase the likelihood of the ultimate repayment of the loan. To control concentration risk, we monitor collateral type concentrations within this portfolio. In addition to these common risks for the majority of our real estate loans, additional risks are inherent in certain of our classes of real estate loans which are addressed below: Commercial Real Estate Commercial real estate loans consist of commercial construction and land development loans and other commercial real estate loans. Commercial construction and land development loans are highly dependent upon the supply and demand for commercial real estate in the markets we serve as well as the demand for newly constructed residential homes and lots that our customers are developing. Construction and development loans generally carry a higher degree of risk than long-term financing of existing properties because repayment depends upon the ultimate completion of the project and usually on the subsequent lease-up and/or sale of the property. Additionally, deterioration in demand could result in significant decreases in the underlying collateral values and make repayment of the outstanding loans more difficult for our customers. Other commercial real estate loans consist primarily of loans secured by other nonfarm nonresidential properties such as retail, office and hotel/motel and multifamily housing. These loans typically have terms of five years or less, although payments may be structured on a longer amortization basis. We evaluate each borrower on an individual basis and attempt to determine the business risks and credit profile of each borrower. The primary risk associated with loans secured with income-producing property is the inability of that property to produce adequate cash flow to service the debt. High unemployment, generally weak economic conditions and/or an oversupply in the market may result in our customer having difficulty achieving adequate occupancy rates. Residential Real Estate Residential real estate loans are typically to individuals and are secured by owner-occupied and investor-owned 1-4 family residential property. We generally originate and hold certain first mortgages and traditional second mortgages, adjustable rate mortgages and home equity lines of credit. We also originate and sell fixed and adjustable rate residential real estate loans in the secondary market. Significant and rapid declines in real estate values can result in residential mortgage loan borrowers having debt levels in excess of the current market value of the collateral. Owner-Occupied Real Estate Owner-occupied loans consist of loans secured by nonfarm nonresidential properties, such as office and industrial properties, churches, convenience stores and restaurants occupied by an affiliated tenant. Loan repayment is primarily dependent on the ability of the operating company to achieve business results consistent with those projected at loan origination resulting in cash flow sufficient to service the debt. Adverse changes in the business's results, specifically declines in cash flows, could jeopardize the ability for the loan to be serviced in accordance with the contractual terms. Commercial, Financial & Agricultural Loans Commercial, financial and industrial loans include loans to individuals and businesses for commercial purposes in various lines of business, including the manufacturing, professional service, and crop production industries. This segment also includes loans to states and political subdivisions. Repayment is primarily dependent on the ability of the borrower to achieve business results consistent with those projected at loan origination resulting in cash flow sufficient to service the debt. To the extent that a borrower's business results are significantly unfavorable versus the original projections, the ability for the loan to be serviced on a basis consistent with the contractual terms may be at risk. While these loans may be partially secured by real estate, they are generally considered to have greater collateral risk than first or second mortgages on real estate because these loans may be unsecured or, if they are secured, the value of the non-real estate collateral may be difficult to assess and less marketable than real estate, and the control of the collateral is more at risk. Leases Leases include equipment finance agreements and purchased commercial, business purpose and municipal leases. Equipment finance agreements are originated and serviced by the Company. These agreements are fully amortizing and recorded at amortized cost. Equipment finance agreements are collateralized by a first security interest in petroleum and convenience store equipment. For purchased leases, the stream of payments and a first security interest in the collateral is assigned to us. Our lease funding is based on a present value of the lease payments at a discounted interest rate, which is determined based on the credit quality of the lessee, the term of the lease compared to expected useful life, and the type of collateral. Types of collateral include, but are not limited to, medical equipment, rolling stock, franchise restaurant equipment and hardware/software. Servicing of purchased leases is primarily retained by the loan originator, as well as ownership of all residuals, if applicable. Lease financing is underwritten by our Specialized Finance or Patriot Capital groups using similar underwriting standards as would be applied to a secured commercial loan requesting high loan-to-value financing. Risks that are involved with lease financing receivables are credit underwriting and borrower industry concentrations. Consumer Loans The consumer loan portfolio includes loans to individuals for personal, family and household purposes, including secured and unsecured installment loans and revolving lines of credit. Consumer loans not secured by real estate are generally considered to have greater risk than first or second mortgages on real estate because they may be unsecured, or, if they are secured, the value of the collateral may be difficult to assess and more likely to decrease in value, and is more difficult to control, than real estate. Consumer loans may be secured by cash value life insurance policies which presents a lower collateral risk than other non-real estate secured consumer loans.

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.

Notes Payable [Abstract]
Notes Payable	NOTE 13: NOTES PAYABLE The Company has several participation agreements with various provisions regarding collateral position, pricing and other matters where the junior participation interests were sold. The terms of the agreements do not convey proportionate ownership rights with equal priority to each participating interest and entitle the Company to receive principal and interest payments before other participating interest holders. Given the participations sold do not qualify as participating interests, they do not qualify for sale treatment in accordance with generally accepted accounting principles. As a result, the Company recorded the transactions as secured borrowings. The balance of the secured borrowings was $1.8 million and $2.8 million at December 31, 2015 and 2014 , respectively. The loans are recorded at their gross balances outstanding and are included in organic loans on the consolidated statements of financial condition.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 14: DERIVATIVES INSTRUMENTS & HEDGING ACTIVITIES Interest Rate Swaps and Caps 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 indicated (dollars in thousands) : Asset Derivatives (1) Liability Derivatives (1) December 31, 2015 December 31, 2014 December 31, 2015 December 31, 2014 Derivatives Designated as Hedging Instruments Interest rate swaps and caps $ 1,262 $ 3,879 $ 1,496 $ 1,666 Derivatives Not Designated as Hedging Instruments Interest rate swaps $ — $ — $ 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 December 31, 2015 , the Company had 94 interest rate swaps with an aggregate notional amount of $162.0 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) : December 31 Interest Rate Products Location 2015 2014 2013 Amount of (loss) gain recognized in income on derivatives Noninterest income $ (956 ) $ (3,031 ) $ 4,589 Amount of gain (loss) recognized in income on hedged items Noninterest income 815 2,422 (3,728 ) Total net (loss) gain recognized in income on fair value hedge ineffectiveness $ (141 ) $ (609 ) $ 861 The Company recognized net (losses) gains of $(141,000) , $(609,000) , and $861,000 during the years ended December 31, 2015 , 2014 , and 2013 , respectively, related to hedge ineffectiveness on the fair value swaps. The Company also recognized a net reduction in interest income of $2.3 million , $2.1 million , and $1.5 million for the years ended December 31, 2015 , 2014 , and 2013 , 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) gains of $(492,000) , $49,000 , and $80,000 in interest income for the years ended December 31, 2015 , 2014 , and 2013 , 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 the 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 years ended December 31, 2015 , 2014 , or 2013 . Amounts reported in AOCI related to derivatives are reclassified to interest expense as the interest rate cap premium is amortized over the life of the cap. During the next twelve months, $1.2 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) : December 31 Interest Rate Products Location 2015 2014 2013 Amount of (loss) gain recognized in income on derivatives (effective portion) OCI $ (2,294 ) $ (2,036 ) $ 1,264 Amount of loss reclassified from AOCI into income (effective portion) Interest expense 546 259 40 Total (loss) gain recognized in consolidated statements of comprehensive income $ (1,748 ) $ (1,777 ) $ 1,304 Interest Rate Swaps Not Designated as Hedging Instruments At December 31, 2015 , the Company had two interest rate swaps with an aggregate notional amount of $6.8 million and liability fair value of $174,000 not designated as fair value hedges associated with the Company's fixed rate loan program. At December 31, 2014 , the Company had no interest rate swaps not designated as fair value hedges. The income statement effect from the derivatives not designated as hedging instruments was net losses of $147,000 , $47,000 , and $21,000 during the years ended December 31, 2015 , 2014 , and 2013 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 in 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 15 , 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 December 31, 2015 , the termination value of derivatives in a net liability position under these agreements was $989,000 , for which the Company posted $330,000 in cash collateral. Although the Company did not breach any provisions at December 31, 2015 , had a breach occurred, the maximum amount of additional collateral the Company would have been required to post to counterparties was $659,000 . 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 December 31, 2015 , the fair value of mortgage derivative assets was $869,000 and the fair value of mortgage derivative liabilities was $505,000 . There were no mortgage derivative fair values or gains/losses in 2014 and 2013. At December 31, 2015 , the Company had approximately $47.3 million of interest rate lock commitments and $85.9 million of forward commitments for the future delivery of residential mortgage loans. The net gain related to interest rate lock commitments used for risk management was $347,000 and the net loss for forward commitments related to these mortgage loans was $34,000 for the year ended December 31, 2015 . The table below presents the effect of the Company's mortgage derivatives not designated as hedging instruments for the periods presented (dollars in thousands) : December 31 Interest Rate Products Location 2015 2014 2013 Amount of gain recognized in income on interest rate lock commitments Noninterest income $ 347 $ — $ — Amount of loss recognized in income on forward commitments Noninterest income (34 ) — — Amount of gain recognized in income on mortgage derivatives not designated as hedging instruments $ 313 $ — $ — 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.

Share-Based Compensation	NOTE 17: SHARE-BASED COMPENSATION The Company maintains an incentive compensation plan that includes share-based compensation. The State Bank Financial Corporation 2011 Omnibus Equity Compensation Plan (the "Plan") was approved by the Company's shareholders in 2011 and authorizes up to 3,160,000 shares of stock for issuance in accordance with the Plan terms. The Plan provides for the granting of Incentive Stock Options, Non-Qualified Stock Options, Performance Awards, Restricted Stock, Restricted Stock Units, Stock Appreciation Rights, Bonus Stock and Stock Awards, or any combination of the foregoing, as the Independent Directors Committee serving as the Compensation Committee determines is best suited to the circumstances of the particular individual. Stock Option Awards Option awards are granted with an exercise price equal to or greater than the market price of the Company's common stock at the date of grant. The options include a vesting period, usually three years, and a ten -year contractual period. Certain option grants provide for accelerated vesting if there is a change in control of the Company or certain other conditions are met, as defined in the Plan document. At all times during the term of the Plan, the Company shall retain the number of shares required to satisfy option exercises as authorized and unissued shares in the Company's treasury. Currently, the Company has a sufficient number of shares allocated to satisfy expected share option exercises. During December 31, 2015 and 2014 , there was no stock option activity. During 2013 , the Company's Board of Directors approved the accelerated vesting of an aggregate of 28,918 unvested stock options upon the retirement of the award holders. The accelerated vesting triggered a modification to the award agreements, the original grants were forfeited and additional grants were awarded based on the new vesting terms. The additional grants awarded were done so at the same exercise price as the original grants. The fair value of each option award is estimated at the grant date using the Black-Scholes option-pricing model. The significant assumptions made and resulting grant-date fair values in utilizing the option-pricing model are noted in the table below: December 31, 2013 Expected volatility 28.6 % Expected dividend yield — % Risk-free interest rate .5 % Expected term (in years) 2.5 Weighted-average grant-date fair value $ 3.48 The 2013 expected volatility, used for the modification of the agreements, was based on the average historical volatility of the Company's stock price. The expected dividend yield is estimated using the current annual dividend level and most recent stock price of the Company's common stock at the date of grant. The risk-free interest rate is determined by using the U.S. Treasury rate for the expected life at the time of grant. The expected term represents the period of time that the stock options granted are expected to be outstanding. There was no compensation expense recognized related to stock options for the years ended December 31, 2015 or 2014 , as all options were vested in 2013 . For the year ended 2013 , the Company recognized compensation expense related to stock options of $14,000 in the consolidated statements of income with a total recognized tax benefit of $5,000 . The amount of compensation expense was determined based on the fair value of options at the time of grant, multiplied by the number of options granted that were expected to vest, which was then amortized over the vesting period. The following table represents a summary of the activity related to stock options: December 31, 2015 Number of Options Weighted Average Exercise Price ($) Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value ($000) Outstanding options, end of year (1) 28,918 $ 14.37 5.65 $ 193 Fully vested and exercisable options, end of year 28,918 $ 14.37 5.65 $ 193 (1) There were no stock option grants, forfeitures or exercises during 2015 . The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2015 . This amount changes based on changes in the market value of the Company’s stock. Restricted Stock Awards The Company has issued both time-based and performance-based shares of restricted stock to certain officers and independent directors under the Plan. The Plan allows for the issuance of restricted stock awards that may not be sold or otherwise transferred until certain restrictions have lapsed. The holders of the restricted stock receive dividends, if applicable, and have the right to vote the shares. The fair value of the restricted stock awarded under the Plan is recorded as unearned share-based compensation. The unearned compensation related to time-based shares of restricted stock is amortized to compensation expense over the vesting period, generally five years. The total share-based compensation expense for these awards is determined based on the market price of the Company's common stock at the date of grant applied to the total number of shares granted and is amortized over the vesting period. During 2015 , the Company's Board of Directors approved the accelerated vesting of an aggregate of 57,381 shares of time-based restricted stock to certain award holders based upon either their retirement or termination. The performance-based shares of restricted stock entitle the recipient to receive shares of the Company’s common stock upon the achievement of performance goals that are specified in the award agreement over a specified performance period. The unearned compensation related to performance-based shares of restricted stock is amortized to compensation expense over the vesting period, generally ten years. The total share-based compensation expense for these awards is determined based on the market price of the Company's common stock at the date of grant applied to the total number of shares granted and is amortized over the vesting period. During 2015 , the Company issued 558,000 performance-based shares of restricted stock with a ten year performance period, of which 92,000 were forfeited. Compensation expense recognized in the Company's consolidated statements of income for restricted stock was $3.6 million , $2.0 million and $1.3 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. The total recognized tax benefit related to the share-based compensation was $1.4 million , $692,000 and $444,000 for 2015 , 2014 and 2013 , respectively. Total unrecognized compensation cost related to unvested share-based compensation was $13.0 million at December 31, 2015 and is expected to be recognized over a weighted-average period of 4.7 years. The following table represents a summary of the unvested restricted stock award activity: December 31, 2015 Shares Weighted Average Grant Date Fair Value Balance, beginning of year 475,046 $ 16.43 Granted 664,706 19.33 Forfeited (94,100 ) 19.06 Earned and issued (65,466 ) 16.52 Balance, end of year 980,186 $ 18.14 Restricted stock awards of 664,706 shares, 153,232 shares, and 181,814 shares, respectively, were granted during 2015 , 2014 and 2013 with a weighted-average grant date fair value of $19.33 , $16.60 and $16.33 , respectively.

Banking and Thrift [Abstract]
Regulatory Matters	NOTE 19: REGULATORY MATTERS Regulatory Capital Requirements The Company and State Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company and State Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and State Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Measures of regulatory capital are an important tool used by regulators to monitor the financial health of financial institutions. The primary quantitative measures used to gauge capital adequacy are the Common Equity Tier 1, Tier 1, Total Capital Ratios to risk-weighted assets (risk-based capital ratios) and the ratio of Tier 1 capital to average total assets (leverage ratio). Failure to meet various capital requirements can initiate regulatory action that could have a direct material effect on the Company and State Bank. Beginning on January 1, 2015, the Company and State 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. 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: December 31, 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) December 31, 2015 capital requirements are under the Basel III framework. December 31, 2014 capital requirements are under the Basel I framework. (2) The prompt corrective action provisions are only applicable at the bank level. At December 31, 2015 and 2014 , the Company and State Bank exceeded all regulatory capital adequacy requirements to which they were subject. The Company's regulatory ratios at the dates indicated are presented in the table below (dollars in thousands) : December 31, 2015 December 31, 2014 Actual Required Actual Required Amount Ratio Minimum Amount Amount Ratio Minimum Amount Company CET1 Capital $ 493,294 17.71 % $ 125,372 N/A N/A N/A Tier 1 Capital 493,294 17.71 % 167,162 $ 446,666 23.12 % $ 77,271 Total Capital 522,369 18.75 % 222,883 470,869 24.37 % 154,543 Tier 1 Leverage 493,294 14.48 % 136,315 446,666 15.90 % 112,334 State Bank's regulatory ratios at the dates indicated are presented in the table below (dollars in thousands) : December 31, 2015 December 31, 2014 Actual Required Actual Required Amount Ratio Minimum Amount Well Capitalized Amount Amount Ratio Minimum Amount Well Capitalized Amount State Bank CET1 Capital $ 427,526 15.42 % $ 124,773 $ 180,227 N/A N/A N/A N/A Tier 1 Capital 427,526 15.42 % 166,364 221,818 $ 359,759 18.63 % $ 77,256 $ 115,883 Total Capital 456,601 16.47 % 221,818 277,273 383,957 19.88 % 154,511 193,139 Tier 1 Leverage 427,526 12.62 % 135,507 169,383 359,759 12.84 % 112,112 140,139 The Company and State Bank entered into a Capital Maintenance Agreement with the FDIC. 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 December 31, 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 State Bank may distribute without prior regulatory approval. At December 31, 2015 , State Bank had no capacity to pay dividends to the Company without prior regulatory approval. At December 31, 2015 , the Company had $50.7 million in cash and due from bank accounts, which can be used for additional capital as needed by the subsidiary bank, payment of holding company expenses, payment of dividends to shareholders or for other corporate purposes. Other Regulatory Matters The Company had required reserve balances at the Federal Reserve Bank of $121.3 million and $99.3 million at December 31, 2015 and 2014 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	NOTE 20: 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 for on-balance-sheet instruments. A summary of the Company's commitments is as follows (dollars in thousands) : December 31 2015 2014 Commitments to extend credit: Fixed $ 28,744 $ 21,276 Variable 502,538 405,956 Letters of credit: Fixed 1,907 846 Variable 4,925 4,350 Total commitments $ 538,114 $ 432,428 The fixed rate loan commitments have maturities ranging from one month to five 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 December 31, 2015 , the recourse liability was $342,000 . 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 21: 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 years ended December 31, 2015 and 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 , Summary of Significant Accounting Policies. 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 December 31, 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. After origination and prior to sale, the mortgage loans held-for-sale accrue interest income, recorded in "interest income" on the consolidated statements of income, based on the contractual terms of the loans. Refer to Note 1 , Summary of Significant Accounting Policies, for more information on the accounting for mortgage loans held-for-sale. At December 31, 2015 , the aggregate fair value of the mortgage loans held-for-sale was $48.8 million and the contractual balance including accrued interest was $47.8 million , with a fair value mark totaling $966,000 . None of the loans were 90 days or more past due or on nonaccrual at December 31, 2015 . 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 $182,000 for the year ended December 31, 2015 . Derivative Financial Instruments 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. The interest rate lock commitments with a positive fair value totaled $290,000 at December 31, 2015 . In addition, the interest rate lock commitments with a negative fair value totaled $71,000 at December 31, 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 income. The forward commitments on interest rate lock commitments with a positive fair value totaled $71,000 at December 31, 2015 . Furthermore, the forward commitments on interest rate lock commitments with a negative fair value totaled $290,000 at December 31, 2015 . SBA Servicing Rights The Company has the rights to service a portfolio of Small Business Administration (“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. The following tables present the 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) : 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 (1) — 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: Interest rate swaps and caps $ — $ 1,670 $ — $ 1,670 Mortgage derivatives (1) — 144 361 505 Total recurring liabilities at fair value $ — $ 1,814 $ 361 $ 2,175 (1) Includes mortgage related interest rate lock commitments and forward commitments to sell.

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. 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 December 31, 2015 Impaired loans $ — $ — $ 5,941 $ 5,941 Total nonrecurring assets at fair value $ — $ — $ 5,941 $ 5,941 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 $7.0 million and $5.7 million with respective valuation allowances of $1.0 million and $486,000 at December 31, 2015 and 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 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 December 31, 2015 Other real estate owned $ — $ — $ 12,110 $ 12,110 December 31, 2014 Other real estate owned $ — $ — $ 10,939 $ 10,939 The following table is a reconciliation of the fair value measurement of other real estate owned disclosed in accordance with ASC Topic 820, Fair Value Measurements and Disclosures , to the amount recorded on the consolidated statements of financial condition (dollars in thousands) : December 31 Other Real Estate Owned 2015 2014 Other real estate owned at fair value $ 12,110 $ 10,939 Estimated selling costs and other adjustments (1,580 ) (2,371 ) Other real estate owned $ 10,530 $ 8,568 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) : 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%) 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 $ 10,939 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 estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies; however, considerable judgment is required to interpret market data in order to develop the estimates of fair value. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation techniques may have a material effect on the estimated fair value amounts at December 31, 2015 and 2014 .

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 The FDIC receivable for loss share agreements was recorded at fair value at each FDIC-assisted 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. 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 formerly covered loan or the life of the loss share agreement. The FDIC receivable for loss share agreements was eliminated as a result of the early termination of loss share coverage in May 2015. 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 The fair value of securities sold under agreements to repurchase approximates the carrying amount because of the short maturity of these borrowings. Notes Payable Notes payable are variable rate subordinated debt for which performance is based on the underlying notes receivable interest rates adjust according to market value; therefore, the carrying amount approximates fair value.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 23: 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) : Years Ended December 31 2015 2014 2013 Numerator: Net income per consolidated statements of income $ 28,423 $ 30,918 $ 12,747 Net income allocated to participating securities (783 ) (434 ) (135 ) Net income allocated to common stock $ 27,640 $ 30,484 $ 12,612 Basic net income per share computation: Net income allocated to common stock $ 27,640 $ 30,484 $ 12,612 Weighted average common shares outstanding, including shares considered participating securities 35,796,497 32,175,363 31,978,844 Less: Average participating securities (985,642 ) (451,392 ) (338,560 ) Weighted average shares 34,810,855 31,723,971 31,640,284 Basic net income per share $ .79 $ .96 $ .40 Diluted net income per share computation: Net income allocated to common stock $ 27,640 $ 30,484 $ 12,612 Weighted average common shares outstanding for basic earnings per share 34,810,855 31,723,971 31,640,284 Weighted average dilutive grants 1,231,864 1,103,972 1,013,820 Weighted average shares and dilutive potential common shares 36,042,719 32,827,943 32,654,104 Diluted net income per share $ .77 $ .93 $ .39 During 2015, the Company identified an error in the computation and disclosure of diluted earnings per share. 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 years ended December 31, 2014 and 2013 .

Nature of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenue and expenses for the period. Actual results could differ significantly from those estimates. Significant estimates include the allowance for loan and lease losses, the valuation of other real estate owned, the amount and timing of expected cash flows from purchased credit impaired loans, the fair value of investment securities and other financial instruments, and the valuation of goodwill. A substantial portion of the Company's loans are secured by real estate located in its market area. Accordingly, the ultimate collectability of a substantial portion of the Company's loan portfolio is susceptible to changes in the real estate market conditions. As defined by authoritative guidance, segment disclosures require reporting information about a company's operating segments using a “management approach.” Reportable segments are identified as those revenue-producing components for which separate financial information is produced internally and which are subject to evaluation by the chief operating decision maker in deciding how to allocate resources to segments. The Company operates as one reportable segment.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents, as presented in the consolidated financial statements, includes cash on hand, cash items in process of collection and interest-bearing deposits with other financial institutions with maturities less than 90 days.
Investments	Investments Management determines the appropriate classifications of investment securities at the time of purchase and reevaluates such designation as needed. At December 31, 2015 and 2014 , the Company classified all of its investment securities as available-for-sale. Investments available-for-sale are reported at fair value, as determined by independent quotations. Purchase premiums and discounts on investment securities are amortized and accreted to interest income using the effective interest rate method over the remaining lives of the securities, taking into consideration assumed prepayment patterns. Realized gains and losses are derived using the specific identification method for determining the cost of securities sold and are recognized on the trade date. Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. In connection with the assessment for other than temporary impairment of investment securities, management obtains fair value estimates by independent quotations, assesses current credit ratings and related trends, reviews relevant delinquency and default information, assesses expected cash flows and coverage ratios, assesses the relative strength of credit support from less senior tranches of the securities, reviews average credit score data of underlying mortgages, and assesses other current data. The severity and duration of impairment and the likelihood of potential recovery of impairment is considered along with the intent and ability to hold any impaired security to maturity or recovery of carrying value. Unrealized holding losses, other than those determined to be other than temporary, and unrealized holding gains are excluded from net income and are reported, net of tax, in other comprehensive income and in accumulated other comprehensive income (loss), a separate component of shareholders' equity. A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for that security. At December 31, 2015 and 2014 , the Company did not have any securities with other than temporary impairment. Investment in stock of the Federal Home Loan Bank ("FHLB") is required of every federally insured financial institution which utilizes the FHLB's services. The investment in FHLB stock is included in "other assets" at its original cost basis, as cost approximates fair value since there is no readily determinable market value for such investments.
Organic Loans	Organic Loans Organic loans, defined as loans not purchased in the acquisition of an institution or credit impaired portfolio, are loans management has the intent and ability to hold for the foreseeable future, until maturity, or until payoff. Organic loans are reported at their principal amounts outstanding, net of unearned income, net of deferred loan fees and origination costs, net of unamortized premiums or discounts on purchased participation loans, and net of the allowance for loan and lease losses. Interest income is recognized using the simple interest method on the daily balance of the principal amount outstanding. Unearned income, primarily arising from deferred loan fees net of certain origination costs, is amortized over the lives of the underlying loans using the effective interest rate method. Past due status is based on the contractual terms of the loan agreement. Generally, the accrual of interest income is discontinued and loans are placed on nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal. Interest previously accrued but not collected is reversed against current period interest income when such loans are placed on nonaccrual status. Interest on nonaccrual loans when ultimately collected is recorded as a principal reduction. Nonaccrual loans are returned to accrual status when all principal and interest amounts contractually due are brought current. In addition, the future payments must be reasonably assured along with a period of at least six months of repayment performance by the borrower depending on the contractual payment terms. When it has been determined that a loan cannot be collected in whole or in part, then the uncollectible portion is charged-off. The Company considers an organic loan impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Additionally, loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings ("TDRs") and are included in impaired loans. The Company's policy requires that all impaired loans with contractual balances of $500,000 and greater be individually reviewed for impairment. Loans are reviewed for impairment based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or the loan's observable market price, or the fair value of the collateral less disposal costs, as applicable, if the loan is collateral dependent. The Company's policy requires that large pools of smaller balance homogeneous loans, such as consumer, residential and installment loans, be collectively evaluated for impairment by the Company. Impairment losses are included in the allowance for loan and lease losses through a provision charge to earnings. All loans considered impaired are placed on nonaccrual status in accordance with policy. The interest portion of cash receipts on impaired loans are recorded as income when received unless full recovery of principal is in doubt whereby cash received is recorded as a reduction to the Company's recorded investment in the loan. All organic impaired loans are reviewed at least quarterly. Reviews may be performed more frequently if material information is available before the next scheduled quarterly review. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. The discounts may include the following: length of time to market and sell the property, as well as expected maintenance costs, insurance and taxes and real estate commissions on sale.
Purchased Loans	Purchased Loans Purchased non-credit impaired loans ("PNCI loans") Loans acquired without evidence of deterioration in credit quality since origination, referred to as purchased non-credit impaired loans, are initially recorded at estimated fair value on the acquisition date. Premiums and discounts created when the loans are recorded at their estimated fair values at acquisition are amortized or accreted over the remaining term of the loan as an adjustment to the related loan's yield. The Company accounts for performing loans acquired in business combinations using the contractual cash flows method whereby premiums and discounts are recognized using the interest method. There is no allowance for loan and lease losses established at the acquisition date for purchased loans. Following the acquisition of these loans, the policies regarding nonaccrual and impaired loan status is consistent with that described above for organic loans. A provision for loan losses is recorded should there be deterioration in these loans subsequent to the acquisition. Purchased credit impaired loans ("PCI loans") Purchased credit impaired loans, defined as acquired loans, which at acquisition, management determined it was probable that the Company would be unable to collect all contractual principal and interest payments due, 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, if appropriate, an accretable discount. The nonaccretable discount, which is excluded from the carrying amount of acquired loans, is the difference between the contractually required payments and the cash flows expected to be collected at acquisition. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan when there is reasonable expectation about the amount and timing of such cash flows. The difference between actual prepayments and expected prepayments does not affect the nonaccretable discount. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows results in either a reversal of the provision for loan losses or a reclassification of the difference from nonaccretable to accretable, both of which have a positive impact on the accretable discount. All loans acquired in failed bank transactions are considered to have evidence of credit deterioration, as limited due diligence is afforded which does not allow a sufficient detailed review to classify the acquired loans into credit deterioration and performing categories. At the time of acquisition, purchased credit impaired loans are either accounted for as specifically-reviewed or as part of a loan pool. Loan pools are created by grouping loans with similar risk characteristics, the intent being to create homogeneous pools. Loans are grouped into pools based on a combination of various factors including product type, cohort, risk classification and term. Loans remain in the assigned pool until the individual pools have resolved. Gains and losses on individual loans within pools are deferred and retained in the pools until the pool closes, which is either when all the loans are resolved or the pool’s aggregate recorded investment reaches zero.
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses ("ALLL") The ALLL represents the amount considered adequate by management to absorb losses inherent in the loan portfolio at the balance sheet date. The ALLL is adjusted through provisions for loan losses charged or credited to operations. The provisions are generated through loss analyses performed on organic loans, estimated additional losses arising on PNCI loans subsequent to acquisition and impairment recognized as a result of decreased expected cash flows on PCI loans due to further credit deterioration since the previous quarterly cash flow re-estimation. The ALLL consists of both specific and general components. Individual loans are charged off against the ALLL when management determines them to be uncollectible. Subsequent recoveries, if any, of loans previously charged-off are credited to the ALLL. All known and inherent losses that are both probable and reasonable to estimate are recorded. While management utilizes available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance. Such agencies may require adjustments to the ALLL based on their judgment about information available at the time of their examination. The Company assesses the adequacy of the ALLL quarterly with respect to organic and purchased loans. The assessment begins with a standard evaluation and analysis of the loan portfolio. All loans are consistently graded and monitored for changes in credit risk and possible deterioration in the borrower’s ability to repay the contractual amounts due under the loan agreements. Allowance for loan and lease losses for organic loans: The ALLL for organic loans consists of two components: (1) a specific amount against identified credit exposures where it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreements; and (2) a general amount based upon historical losses that are then adjusted for qualitative factors representative of various economic indicators and risk characteristics of the loan portfolio. Management establishes the specific amount by examining impaired loans. The majority of the Company's impaired loans are collateral dependent; therefore, nearly all of the specific allowances are calculated based on the fair value of the collateral less disposal costs, if applicable. Management establishes the general amount by reviewing the remaining loan portfolio (excluding those impaired loans discussed above) and incorporating allocations based on historical losses. The calculation of the general amount is subjected to qualitative factors that are somewhat subjective. The qualitative testing attempts to correlate the historical loss rates with current economic factors and current risks in the portfolio. The qualitative factors consist of but are not limited to: (1) economic factors including changes in the local or national economy; (2) the depth of experience in lending staff; (3) asset quality trends; and (4) seasoning and growth rate of the portfolio segments. After assessing the applicable factors, the remaining amount is evaluated based on management's experience and the level of the organic ALLL is compared with historical trends and peer information as a reasonableness test. Allowance for loan and lease losses for purchased loans: Purchased loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan and lease losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for purchased loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, default rates, loss severity, collateral values, discount rates, payment speeds, prepayment risk and liquidity risk. The Company maintains an ALLL on purchased loans based on credit deterioration subsequent to the acquisition date. For purchased credit impaired loans accounted for under ASC 310-30, management establishes an allowance for credit deterioration subsequent to the date of acquisition by quarterly re-estimating expected cash flows with any decline in expected cash flows recorded as impairment in the provision for loan losses. Impairment is measured as the excess of the recorded investment in a loan over the present value of expected future cash flows discounted at the pre-impairment accounting yield of the loan. For any increases in cash flows expected to be collected, the Company first reverses only previously recorded ALLL, then adjusts the amount of accretable yield recognized on a prospective basis over the loan’s remaining life. For purchased loans that are not deemed impaired at acquisition, also referred to as purchased non-credit impaired loans, credit discounts representing the principal losses expected over the life of the loan are a component of the initial fair value and the discount is accreted to interest income over the life of the asset. Subsequent to the purchase date, the method used to evaluate the sufficiency of the credit discount is similar to originated loans, and if necessary, additional reserves are recognized in the allowance for loan and lease losses.
Loans Held-for-Sale	Loans Held-for-Sale 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. Mortgage Loans Held-for-Sale Concurrent with the First Bank acquisition in January 2015, the Company made the election to record mortgage loans held-for-sale at fair value under the fair value option on a prospective basis. Mortgage loans held-for-sale were previously recorded at the lower of cost or fair value. 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. Net origination fees and costs are recognized in earnings at the time of origination for residential mortgage loans held-for-sale. Gains and losses on mortgage loan sales 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, are classified on the consolidated statements of income as noninterest income - mortgage banking income. The loan sales agreements 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. SBA Loans Held-for-Sale SBA loans held-for-sale are recoded 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 part of the basis of the loan and are included in the calculation of realized gains and losses upon sale. Gains and losses are classified on the consolidated statements of income as noninterest income - SBA income. All SBA loan sales are executed on a servicing retained basis - refer to Small Business Administration ("SBA") Servicing Rights below for more information .
Other Real Estate Owned (OREO)	Other Real Estate Owned ("OREO") Other real estate owned consists of real property (a) acquired through mergers and acquisitions, (b) acquired through foreclosure in satisfaction of loans receivable, and (c) banking premises formerly, but no longer, used for a specific business purpose. Other real estate is distinguished between organic, purchased non-credit impaired, or purchased credit impaired, consistent with the categories, respectively, at time of transfer. Real property acquired through mergers and acquisitions are recorded at fair value on Day 1 of the acquisition. Real estate acquired through foreclosure of loans, consisting of properties obtained through foreclosure proceedings or acceptance of a deed in lieu of foreclosure, is reported on an individual asset basis at the lower of cost or fair value, less costs to sell with any excess in loan balance charged against the allowance for loan and lease losses. Banking premises no longer used for a specific business purposes is transferred into OREO at the lower of its carrying value or fair value, less estimated costs to sell with any excess in carrying value charged to noninterest expense. For all fair value estimates of the real estate properties, fair value is determined on the basis of current appraisals, comparable sales, current market conditions, and other estimates of value obtained principally from independent sources. Management periodically reviews the carrying value of OREO for subsequent declines in fair value and adjusts the values as appropriate through noninterest expense. Gains or losses recognized on the disposition of the properties are recorded on the consolidated statements of income as "loan collection costs and OREO activity". Costs of improvements to real estate are capitalized, while costs associated with holding the real estate are charged to income. Prior to termination of the Company's loss share agreements with the FDIC in May 2015, OREO formerly covered under the agreements were reported exclusive of expected reimbursement cash flows from the FDIC. Subsequent adjustments to the estimated recoverable value of the other real estate resulted in a reduction of other real estate and a charge to other expense. The FDIC receivable was increased for the estimated amount to be reimbursed, with a corresponding offsetting amount recorded to other expense. Costs associated with holding the formerly covered other real estate were charged to income, net of any expected reimbursements from the FDIC relating to previously covered external expenses.
Premises and Equipment	remises and Equipment Premises and equipment are stated at cost, less accumulated depreciation, which is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of the assets range from 10 to 25 years for buildings and improvements and 3 to 15 years for furniture, fixtures, and equipment. Costs of improvements are capitalized and depreciated, while operating expenses are charged to current earnings.
Goodwill and Other Intangibles, Net	oodwill and Other Intangibles, Net Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangibles deemed to have an indefinite life are not amortized but instead are subject to review for impairment annually, or more frequently if deemed necessary. Also in connection with business combinations, the Company records core deposit intangibles, representing the value of the acquired core deposit base, and other identifiable intangible assets. Core deposit intangibles and other identifiable intangible assets are amortized on a straight-line basis over their estimated useful lives ranging up to 10 years.
Small Business Administration (SBA) Servicing Rights	mall Business Administration ("SBA") Servicing Rights All sales of SBA loans, consisting of the guaranteed portion, are executed on a servicing retained basis. The standard sale structure under the SBA Secondary Participation Guaranty Agreement provides for the Company to retain a portion of the cash flow from the interest payment received on the loan. This cash flow is commonly known as a servicing spread. For any guaranteed loans sold at a premium, SBA regulations require the lender to keep a minimum 100 basis points in servicing spread which includes a minimum service fee of 40 basis points and a minimum premium protection fee of 60 basis points. The servicing spread is recognized as a servicing asset to the extent the spread exceeds adequate compensation for the servicing function. The fair value of the servicing asset is measured on a recurring basis at the present value of future cash flows using market-based discount assumptions. The future cash flows for each asset are based on their unique characteristics and 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. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned.
FDIC Receivable for Loss Share Agreements	DIC Receivable for Loss Share Agreements and Clawback Liability On May 21, 2015, State Bank entered into an agreement with the FDIC to terminate loss share coverage on all 12 FDIC-assisted acquisitions. The termination resulted in the elimination of both the FDIC receivable for loss share agreements and the associated clawback liability. The FDIC receivable for loss share agreements was measured separately from the related formerly covered assets and was not contractually embedded in the assets or transferable if the assets were sold. The fair value of the FDIC receivable was estimated at acquisition using projected cash flows related to loss share agreements based on the expected reimbursements for losses using the applicable loss share percentages. The cash flows were discounted to reflect the estimated timing of the receipt of the loss share reimbursements from the FDIC. The FDIC receivable was reviewed and updated prospectively as loss estimates related to formerly covered assets changed and as reimbursements were received or were expected to be received from the FDIC. Improvements in the credit quality or cash flows of formerly covered loans (reflected as an adjustment to yield and accreted into income over the remaining life of the covered loans) decreased the basis of the FDIC receivable, with decreases being amortized into income over the remaining life of the loan or life of the loss share agreement, whichever was shorter. Any applicable true-up payments owed the FDIC for loss share agreements with clawback provisions were discounted to reflect the estimated timing of the payment and such amount was reported as a liability in "other liabilities" on the consolidated statements of financial condition. In addition, recoveries of FDIC-indemnified losses on loans were reimbursed to the FDIC during the coverage period under the loss share agreements.
Derivative Instruments and Hedging Activities	erivative Instruments and Hedging Activities Interest Rate Swaps and Caps The Company enters into derivative financial instruments to manage interest rate risk, facilitate asset/liability management strategies and manage other exposures. These instruments may include interest rate swaps and interest rate caps and floors. All derivative financial instruments are recognized on the consolidated statements of financial condition as other assets or other liabilities, as applicable, at estimated fair value. The Company enters into master netting agreements with counterparties and/or requires collateral to cover exposures. In most cases, counterparties post at a zero threshold regardless of rating. Interest rate swaps are agreements to exchange interest payments based upon notional amounts. Interest rate swaps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform. Option contracts involve rights to buy or sell financial instruments on a specified date or over a period at a specified price. These rights do not have to be exercised. Some option contracts such as interest rate caps, involve the exchange of cash based on changes in specified indices. Interest rate caps are contracts to hedge interest rate increases based on a notional amount. Interest rate caps subject the Company to market risk associated with changes in interest rates, as well as the credit risk that the counterparty will fail to perform. Derivative financial instruments are designated, based on the exposure being hedged, as either fair value or cash flow hedges. Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Under the fair value hedging model, gains or losses attributable to the change in fair value of the derivative instrument, as well as the gains and losses attributable to the change in fair value of the hedged item, are recognized in other noninterest income in the period in which the change in fair value occurs. Hedge ineffectiveness is recognized as other noninterest income to the extent the changes in fair value of the derivative do not offset the changes in fair value of the hedged item. The corresponding adjustment to the hedged asset or liability is included in the basis of the hedged item, while the corresponding change in the fair value of the derivative instrument is recorded as an adjustment to other assets or other liabilities, as applicable. Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. For cash flow hedge relationships, the effective portion of the gain or loss related to the derivative instrument is recognized as a component of accumulated other comprehensive income (loss). The ineffective portion of the gain or loss related to the derivative instrument, if any, is recognized in earnings as other noninterest income during the period of change. Amounts recorded in accumulated other comprehensive income (loss) are recognized in earnings in the period or periods during which the hedged item impacts earnings. The Company formally documents all hedging relationships between hedging instruments and the hedged items, as well as its risk management objective and strategy for entering into various hedge transactions. Methodologies related to hedge effectiveness and ineffectiveness are consistent between similar types of hedge transactions and typically include (i) statistical regression analysis of changes in the cash flows of the actual derivative and a perfectly effective hypothetical derivative, and (ii) statistical regression analysis of changes in the fair values of the actual derivative and the hedged item. The Company performs retrospective and prospective effectiveness testing using quantitative methods and does not assume perfect effectiveness through the matching of critical terms. Assessments of hedge effectiveness and measurements of hedge ineffectiveness are performed at least quarterly for ongoing effectiveness. Hedge accounting is discontinued prospectively when (i) a derivative is no longer highly effective in offsetting changes in the fair value or cash flows of a hedged item, (ii) a derivative expires or is sold, terminated or exercised, (iii) we elect to discontinue the designation of a derivative as a hedge, or (iv) in a cash flow hedge, a derivative is de-designated because it is not probable that a forecasted transaction will occur. If a derivative that qualifies as a fair value or cash flow hedge is terminated or the designation removed, the realized or then unrealized gain or loss is recognized in income over the life of the hedged item (fair value hedge) or in the period in which the hedged item affects earnings (cash flow hedge). Immediate recognition in earnings is required upon sale or extinguishment of the hedged item (fair value hedge) or if it is probable that the hedged cash flows will not occur (cash flow hedge). Derivatives continued to be held after hedge accounting ceases are carried at fair value on the consolidated statements of financial condition with changes in fair value including in earnings. Mortgage Derivatives The Company enters derivative financial instruments to manage interest rate risk and pricing risk associated with is mortgage banking activities. These instruments may include interest rate lock commitments and forward commitments. All mortgage derivatives are recognized on the consolidated statements of financial condition as other assets or other liabilities, as applicable, at estimated fair value and are not accounted for as hedges. Interest rate lock commitments are agreements to fund fixed-rate mortgage loans to customers. Forward commitments are agreements to sell fixed-rate mortgage loans to investors. Changes in fair value are recognized "mortgage banking income" on the consolidated statements of income.
Bank-Owned Life Insurance (BOLI)	ank-Owned Life Insurance ("BOLI") The Company has purchased life insurance policies on certain key executives. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value that is probable at settlement. Increases to cash surrender values are recorded as "Bank-owned life insurance income" on the consolidated statements of income. The Company has entered into a split dollar agreement with certain of its executives whereby the executive’s designated beneficiary will receive a portion of the death benefit upon the executive officer’s death. The Company uses the cost of insurance method whereby a liability is recorded relating to the benefit provided that extends to post-retirement periods.
Share-Based Compensation	hare-Based Compensation The Company has an equity compensation plan providing for the grant of equity awards, which is described more fully in Note 17 . The Company uses the fair value method of recognizing expense for share-based compensation, whereby compensation cost is measured at the grant date based on the value of the award and is recognized on a straight-line basis over the vesting period. Compensation expense relating to equity awards is reflected in net income as part of "salaries and employee benefits" on the consolidated statements of income.
Income Taxes	ncome Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies by jurisdiction and entity in making this assessment. Interest and penalties related to the Company’s tax positions are recognized as a component of the income tax provision.
Comprehensive Income	omprehensive Income In addition to net income for the period, comprehensive income for the Company consists of changes in unrealized holding gains and losses on investments classified as available-for-sale and changes in fair value of the effective portion of derivative financial instruments designated as cash flow hedges. The changes are reported net of income taxes and reclassification adjustments.
Acquisitions	cquisitions Accounting principles generally accepted in the United States of America ("US GAAP") require that the acquisition method of accounting, formerly referred to as the purchase method, be used for all business combinations and that an acquirer be identified for each business combination. Under US GAAP, the acquirer is the entity that obtains control of one or more businesses in the business combination, and the acquisition date is the date the acquirer achieves control. US GAAP requires that the acquirer recognize the fair value of assets acquired, liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date.
Basic and Diluted Net Income Per Share	asic and Diluted Net Income Per Share Basic net income per share is calculated using the two-class method to determine income attributable to common shareholders. Unvested share-based payment awards that contain nonforfeitable rights to dividends are considered participating securities under the two-class method. Net income attributable to common shareholders is then divided by the weighted average common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the net income of the Company. Diluted net income per share is computed by dividing net income attributable to common shareholders by the total of the weighted average number of shares outstanding plus the dilutive effect of the outstanding options and warrants.
Adoption of New Accounting Standards and Recent Accounting Pronouncements	Adoption of New Accounting Standards ASU 2014-04 — In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU) No. 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 6 , Other Real Estate Owned. ASU 2014-11 — In June 2014, 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 September 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, although it did result in additional disclosures. For more information about these disclosures, refer to Note 15 , Balance Sheet Offsetting. Recent Accounting Pronouncements ASU 2016-01 — In January 2016, FASB issued Accounting Standards Update (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 (viii) 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 2015-16 — In September 2015, 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. The accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and 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. ASU 2015-14 and ASU 2014-09 — In August 2015, FASB issued Accounting Standards Update (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. ASU 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 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. 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. 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.
