CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this report that are not statements of historical fact are forward-looking statements. These forward-looking statements, which are based on certain assumptions and describe our future plans, strategies and expectations, can generally be identified by the use of the words "may," "would," "could," "will," "expect," "anticipate," "project," "believe," "intend," "seek," "plan" and "estimate," as well as similar expressions. These forward-looking statements include, but are not limited to, statements related to our proposed merger with Cadence Bancorporation ("Cadence"), including the expected timing to close the transaction, our expectations regarding growth in our markets, our belief that our deposits are attractive sources of funding because of their stability and relative cost, our plan to meet future cash needs through the generation of deposits, our anticipation that a significant portion of our commercial and residential real estate construction and consumer equity lines of credit will not be funded, our expectation regarding the impact of the new capital and liquidity standards on the Company and State Bank, our belief that our recorded deferred tax assets are fully recoverable, as well as statements relating to the anticipated effects on results of operations and financial condition from expected developments or events, and our use of derivatives and their anticipated future effect on our financial statements.

These forward-looking statements involve significant risks and uncertainties that could cause our actual results to differ materially from those anticipated in such statements. Potential risks and uncertainties include those described under "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2017, and the following:

• the occurrence of any event, change or other circumstances that could give rise to the right of Cadence or us to terminate the definitive merger agreement;

• the outcome of any legal proceedings that may be instituted against Cadence or us;

• the failure to obtain necessary regulatory approvals for our merger with Cadence (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction), and approval of our shareholders or to satisfy any of the other conditions to the merger on a timely basis or at all;

• the possibility that the anticipated benefits of the merger with Cadence are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where we and Cadence and do business;

• the possibility that the merger with Cadence may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities;

• potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the merger with Cadence;

• Cadence’s ability to complete the acquisition and integration of the Company and State Bank successfully, and other factors that may affect ours or Cadence’s future results;

• negative reactions to our recent acquisitions of each bank's customers, employees and counterparties or difficulties related to the transition of services;

• general economic conditions (both generally and in our markets) may be less favorable than expected, which could result in, among other things, a deterioration in credit quality, a reduction in demand for credit and a decline in real estate values;

• a general decline in the real estate and lending markets, particularly in our market areas, could negatively affect our financial results;

• risk associated with income taxes including the potential for adverse adjustments and the inability to fully realize deferred tax benefits;

• increased cybersecurity risk, including potential network breaches, business disruptions or financial losses;

• our ability to raise additional capital may be impaired based on conditions in the capital markets;

• costs or difficulties related to the integration of the banks we have acquired may be greater than expected;

• current or future restrictions or conditions imposed by our regulators on our operations may make it more difficult for us to achieve our goals;

• legislative or regulatory changes, including changes in accounting standards and compliance requirements, may adversely affect us;

• competitive pressures among depository and other financial institutions may increase significantly;

• changes in the interest rate environment may reduce the volumes or values of the loans we make or have acquired;

1

• other financial institutions may be able to develop or acquire products that enable them to compete more successfully than we can;

• our ability to attract and retain key personnel can be affected by the increased competition for experienced employees in the banking industry;

• adverse changes may occur in the bond and equity markets;

• war or terrorist activities may cause deterioration in the economy or cause instability in credit markets;

• economic, geopolitical or other factors may prevent the growth we expect in the markets in which we operate; and

• we will or may continue to face the risk factors discussed from time to time in the periodic reports we file with the Securities and Exchange Commission ("SEC").

For these forward-looking statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. You should not place undue reliance on the forward-looking statements, which speak only as of the date of this report. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. See Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2017 and Quarterly Reports on Form 10-Q for a description of some of the important factors that may affect actual outcomes.

STATE BANK FINANCIAL CORPORATION AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: BASIS OF PRESENTATION

Overview

State Bank Financial Corporation (the "Company" or "we") is a bank holding company whose business is primarily conducted through its wholly-owned banking subsidiary, State Bank and Trust Company (the "Bank" or "State Bank"). We operate a full service banking business and offer a broad range of commercial and retail banking products to our customers throughout seven of Georgia's eight largest metropolitan statistical areas, or MSAs.

The accompanying unaudited consolidated financial statements for the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statement presentation. The interim consolidated financial statements included herein are unaudited, but reflect all adjustments, consisting of normal and recurring items, which, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the interim period presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the period ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements and notes thereto and the report of our independent registered public accounting firm included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Certain amounts have been reclassified to conform to the current period presentation. The reclassifications had no effect on net income or shareholders’ equity as previously reported.

Proposed Merger with Cadence Bancorporation

On May 11, 2018, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Cadence Bancorporation, a Delaware corporation ("Cadence"). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, the Company will merge with and into Cadence, with Cadence continuing as the surviving corporation. Immediately following the completion of the merger, the Bank will merge with and into Cadence’s wholly owned bank subsidiary, Cadence Bank, N.A. (“Cadence Bank”), with Cadence Bank continuing as the surviving bank. Subject to the terms and conditions of the Merger Agreement, if the merger is completed, Company shareholders will receive 1.160 shares of Cadence Class A common stock, par value $0.01 per share, for each share of Company common stock, par value $0.01 per share, they hold immediately prior to the merger, plus cash in lieu of fractional shares.

The transaction is expected to close in the fourth quarter of 2018, subject to Company shareholder and regulatory approvals in addition to satisfaction of certain other closing conditions.

ASU 2018-05 — In March 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The purpose of this ASU is to codify the SEC's guidance issued in Staff Accounting Bulletin 118. The amendments in this update were effective upon issuance. The adoption did not have a material impact on our consolidated financial statements.

ASU 2018-04 — In March 2018, FASB issued ASU 2018-04, Investment - Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273. The purpose of this ASU is to codify the SEC's guidance issued in Staff Accounting Bulletin 117. The amendments in this update were effective upon issuance. The adoption did not have a material impact on our consolidated financial statements.

ASU 2017-12 — On August 28, 2017, FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.The purpose of this ASU is to better align a company’s risk management

activities and financial reporting for hedging relationships with the economic objectives of those activities, simplify the hedge accounting requirements, and improve the disclosures of hedging arrangements. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted the amendments in this ASU effective January 1, 2018. The adoption changed the location of changes in fair value of the hedging instrument and hedged item to interest income for periods subsequent to adoption and enhanced disclosures of derivatives and hedging activities. The Company did not elect to modify the measurement methodology for any fair value hedges existing as of the adoption date and there was no cumulative effect adjustment required upon adoption. See Note 8 for enhanced disclosures.

ASU 2018-03 — In February 2018, FASB issued ASU 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10). This Update clarifies certain aspects of the guidance issued in ASU 2016-01 including (i) that an entity measuring an equity security using the measurement alternative may make an irrevocable election to change its measurement approach to a fair value method under Topic 820 for that security and any identical or similar investments of the same issuer, (ii) that fair value adjustments under the measurement alternative should be as of the date the observable transaction for a similar security occurred, (iii) requiring the remeasurement of the entire value of forward contracts and purchased options when observable transactions occur on the underlying equity securities, (iv) that financial liabilities for which the fair value option is elected should follow the guidance in paragraph 825-10-45-5, (v) that changes in the fair value of financial liabilities for which the fair value option is elected relating to the instrument-specific credit risk should first be measured in the currency of denomination and then both components of the change in fair value should be remeasured into the reporting entity's functional currency using end-of-period spot rates, and (vi) that the prospective transition approach should only be applied for instances in which the measurement alternative is applied. The guidance was effective for interim periods beginning after June 15, 2018 and may be early adopted provided ASU 2016-01 was adopted. The Company adopted the amendments in this ASU effective January 1, 2018. The adoption did not have a material impact on our consolidated financial statements.

ASU 2016-01 — In January 2016, FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. The accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted the amendments in this ASU effective January 1, 2018. The adoption of 2016-01 resulted in a reclassification of unrealized loss of $23,000 from accumulated other comprehensive loss to retained earnings.

The new guidance, which does not apply to financial instruments, provides that revenue should be recognized for the transfer of goods or services to customers in an amount equal to the consideration the entity receives or expects to receive in exchange for those goods or services. The guidance also includes expanded disclosure requirements that provide comprehensive information about the nature, amount, timing, and uncertainty of

10

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

revenue and cash flows arising from contracts with customers. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company adopted the amendments in this ASU effective January 1, 2018 using the modified retrospective method. Since there was no change to net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not necessary. See below for additional information related to revenue generated from contracts with customers.

Revenue Recognition

On January 1, 2018 the Company adopted ASC Topic 606, using the modified retrospective method. Disclosures of revenue from contracts with customers for periods beginning after January 1, 2018 are presented under ASC Topic 606 and have not materially changed from the prior year amounts. Consistent with this guidance, noninterest income within the scope of this guidance is recognized as services are transferred to our customers in an amount that reflects the considerations we expect to be entitled to in exchange for those services. The Company's revenue streams that were in scope include service charges on deposits, payroll and insurance income, ATM income and other noninterest income.

Services Charges on Deposits - Service charges on deposits primarily consist of monthly maintenance charges, correspondent bank service charges, analysis charges and NSF charges. The fee for NSF charges and certain service charges are fixed and the performance obligation is typically satisfied at the time of the related transaction. The consideration for analysis charges and monthly maintenance charges are variable as the fee can be reduced if the customer meets certain qualifying metrics. The Company's performance obligations are satisfied either at the time of the transaction or over the course of a month.

Payroll and insurance income - Payroll and insurance income consists principally of payroll processing fees, property and casualty brokerage and employee benefits brokerage. Payroll processing fees are charged as the services are provided and the Company satisfied its performance obligation simultaneously. Property and casualty includes the brokerage of both personal and commercial coverages. The placement of the policy is completion of the Company's performance obligation and revenue is recognized at that time. The Company's commission is a percentage of the premium. Employee benefits brokerage consists of assisting companies in designing and managing comprehensive employee benefit programs. The services provided by the Company are collectively benefit management services which are considered a bundle of services that are highly interrelated. Each of the underlying services are activities to fulfill the benefit management service and are not distinct and separate performance obligations. Revenue is recognized over the contract term as services are rendered on a monthly basis. Customer payments are usually received on a monthly basis.

ATM Income - ATM income represents revenues earned from interchange fees and merchant processing fees. Interchange revenues are earned on debit card transactions conducted with payment networks. ATM fees primarily consist of surcharges assessed to our customers for using a non-Bank ATM or a non-Bank customer using our ATM. Such fees generally are recognized concurrently with the delivery of services on a daily basis.

Other - Other noninterest income primarily consists of certain transaction based fees where the performance obligation is satisfied simultaneously with the revenue recognition.

Contract Costs - Costs associated with revenue from contracts with customers related primarily to contracts that have a period of one year or less. The Company has elected to expense the associated costs as incurred.

Contract Balances - The Company records contract assets when revenue is recognized prior to receipt of consideration from the customer. The Company does not have material contract assets at period-end. The Company records contract liabilities when the consideration is received or due in advance of providing services to customers. The Company typically receives payments for its services during the period or at the time services are provided and does not have material contract liabilities at period-end.

Recent Accounting Pronouncements

ASU 2017-09 — On May 10, 2017, FASB issued ASU 2017-09, Scope of Modification Accounting. This Update amends the scope of modification accounting for share-based payment arrangements. It provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718, Compensation—Stock Compensation. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions and classification of the awards are the same immediately before and after the modification. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after

11

STATE BANK FINANCIAL CORPORATION AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 15, 2017. Early adoption is permitted, including adoption in any interim period. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2017-08 — In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The premium on individual callable debt securities shall be amortized to the earliest call date. This guidance does not apply to securities for which prepayments are estimated on a large number of similar loans where prepayments are probable and reasonably estimable. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. This update should be adopted on a modified retrospective basis with a cumulative-effect adjustment to retained earnings on the date of adoption. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2017-04 — In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The Company should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value. The impairment charge is limited to the amount of goodwill allocated to that reporting unit. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2017-01 — In January 2017, FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The ASU clarifies the definition of a business to assist with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2016-13 — In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU changed the credit loss model on financial instruments measured at amortized cost, available for sale securities and certain purchased financial instruments. Credit losses on financial instruments measured at amortized cost will be determined using a current expected credit loss model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. Purchased financial assets with more-than-insignificant credit deterioration since origination ("PCD assets") measured at amortized cost will have an allowance for credit losses established at acquisition as part of the purchase price. Subsequent increases or decreases to the allowance for credit losses on PCD assets will be recognized in the income statement. Interest income should be recognized on PCD assets based on the effective interest rate, determined excluding the discount attributed to credit losses at acquisition. Credit losses relating to available-for-sale debt securities will be recognized through an allowance for credit losses. The amount of the credit loss is limited to the amount by which fair value is below amortized cost of the available-for-sale debt security. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted and if early adopted, all provisions must be adopted in the same period. The amendments should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the period adopted. A prospective approach is required for securities with other-than-temporary impairment recognized prior to adoption. The Company is still reviewing the impact of the adoption of this guidance and has established a cross-functional implementation team. The Company expects the allowance for credit losses to increase upon adoption with a corresponding adjustment to retained earnings. The ultimate amount of the increase will depend on the portfolio composition, credit quality, economic conditions and reasonable and supportable forecasts at that time.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

ASU 2016-02 — In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires the recognition of assets and liabilities arising from the lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend on the classification of the lease as either a finance or an operating lease. Initial costs directly attributable to negotiating and arranging the lease will be included in the asset. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. Lessees will also be required to provide additional qualitative and quantitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements and provide additional information about the nature of an organization’s leasing activities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company expects to elect the package of practical expedients that allows it to not reassess whether any expired or existing contracts represent leases, the lease classification of any expired or existing lease and initial direct costs for any existing or expired leases. The Company expects this standard will have a material impact on its financial statements through gross-up of the balance sheet for lease assets and liabilities. However, no material change to lease expense recognition is expected.

NOTE 3: ACQUISITIONS

Acquisition of AloStar Bank of Commerce

On September 30, 2017, State Bank completed its acquisition of AloStar Bank of Commerce ("AloStar"). State Bank Interim Corp., a wholly-owned subsidiary of State Bank, merged with and into AloStar, immediately followed by the merger of AloStar with and into State Bank. Under the terms of the merger agreement, each share of AloStar common stock was converted into the right to receive $24.26 in cash. Total consideration paid was approximately $195.0 million and the final merger consideration was distributed in October 2017.

The merger of AloStar was accounted for under the acquisition method of accounting. Assets acquired, liabilities assumed and consideration exchanged were recorded at their respective acquisition date fair values. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available. Goodwill of $7.1 million was generated from the acquisition, all of which is expected to be deductible for income tax purposes.

At June 30, 2018, the Company held 155 debt securities that were in an unrealized loss position. Market changes in interest rates and credit spreads may result in temporary unrealized losses as market prices of securities fluctuate. The Company reviews its investment portfolio on a quarterly basis for indications of other than temporary impairment ("OTTI"). The severity and duration of impairment and the likelihood of potential recovery of impairment is considered along with the intent and ability to hold any impaired security to maturity or recovery of carrying value. More specifically, when analyzing the nonagency portfolio, the Company uses cash flow models that estimate cash flows on security-specific collateral and the transaction structure. Future expected credit losses are determined by using various assumptions, the most significant of which include current default rates, prepayment rates and loss severities. Credit information is available and modeled at the loan level underlying each security during the OTTI analysis; the Company also considers information such as loan to collateral values, FICO scores and geographic considerations, such as home price appreciation or depreciation. These inputs are updated quarterly or as changes occur to ensure that the most current credit and other assumptions are utilized in the analysis. If, based on the analysis, the Company does not expect to recover the entire amortized cost basis of the security, the expected cash flows are discounted at the security's initial effective interest rate to arrive at a present value amount. OTTI credit losses reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of these securities. At June 30, 2018, there was no intent to sell any of the securities in an unrealized loss position, and it is more likely than not the Company will not be required to sell these securities. Furthermore, the present value of cash flows expected to be collected exceeded the Company's amortized cost basis of the debt securities; therefore, these securities are not deemed to be other than temporarily impaired.

During the second quarter of 2018, the Company transferred a $10.1 million corporate security from held-to-maturity to available-for-sale. The issuing corporation is the target of a merger which caused the Company to change its assessment of the issuing corporation's creditworthiness. Subsequently, the Company sold a $4.0 million portion of this debt security's par value.

The composition of debt 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. Debt securities with an aggregate fair value of $103.9 million and $116.1 million at June 30, 2018 and December 31, 2017, respectively, were pledged to secure public deposits and repurchase agreements.

Purchased credit impaired loans are initially recorded at fair value at the acquisition date. The Company re-estimates expected cash flows on purchased credit impaired loans on a quarterly basis. 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 first 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 on purchased credit impaired loans are presented in the following table for the periods presented (dollars in thousands):

	Three Months Ended						Six Months Ended

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 purchased credit impaired loans.

At June 30, 2018 and December 31, 2017, loans with a carrying value of $3.1 billion were pledged for lines of credit. At June 30, 2018, consumer mortgage loans secured by residential real estate properties totaling $104,000 were in formal foreclosure proceedings.

For each period indicated, a portion of the Company's purchased credit impaired loans were past due, including many that were 90 days or more past due; however, such delinquencies were included in the Company's performance expectations in determining the fair values of purchased credit impaired loans at each acquisition and at subsequent valuation dates. All purchased credit impaired loan cash flows and the timing of such cash flows continue to be estimable and probable of collection and thus accretion income continues to be recognized on these assets. As such, the referenced purchased credit impaired loans are not considered nonperforming assets.

Asset Quality Grades:

The Company assigns loans into risk categories based on relevant information about the ability of borrowers to pay their debts, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. A loan's risk grade is assigned at inception based upon the strength of the repayment sources and reassessed periodically throughout the year. Loans over certain dollar thresholds identified as having weaknesses are subject to more frequent review. In addition, the Company's internal loan review department provides an ongoing, comprehensive and independent assessment of credit risk within the Company.

Loans are graded on a scale of 1 to 9. 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

32

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

Loss (Grade 9)—Loans classified as loss are considered uncollectible and have little value to the Company and their continuance as an active relationship is not warranted.

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

Total troubled debt restructurings (TDRs) were $6.9 million at June 30, 2018, with $28,000 in related allowance. At December 31, 2017, TDRs totaled $1.5 million with no related allowance. At June 30, 2018, there was one commitment to extend credit to a borrower with an existing troubled debt restructuring totaling $599,000. At December 31, 2017, there were no commitments to extend credit to borrowers with an existing troubled debt restructuring. Purchased credit impaired loans modified post-acquisition are not removed from their accounting pools and accounted for as TDRs, even if those loans would otherwise be deemed TDRs.

There were no loans modified as a TDR during the three months endedJune 30, 2018 or 2017. During the six months endedJune 30, 2018, there was one loan modified as a TDR which subsequently defaulted within twelve months of its modification date with a recorded investment of $848,000. During the six months ended June 30, 2017, there were no TDRs that subsequently defaulted within twelve months of their modification dates.

NOTE 7: SBA SERVICING RIGHTS

All sales of SBA loans, consisting of the guaranteed portion, are executed on a servicing retained basis. These loans, which are partially guaranteed by the SBA, are generally secured by business property such as real estate, inventory, equipment and accounts receivable. During the three and six months ended June 30, 2018, the Company sold SBA loans with unpaid principal balances totaling $9.8 million and $18.4 million, respectively, and recognized $1.0 million and $1.9 million in gains on the loan sales, respectively. During the three and six months ended June 30, 2017, the Company sold SBA loans with unpaid principal balances totaling $16.5 million and $25.0 million, respectively, and recognized $1.6 million and $2.5 million in gains on the loan sales, respectively. The Company retains the related loan servicing rights and receives servicing fees on the sold loans. Both the servicing fees and the gains on sales of loans are recorded in SBA income on the consolidated statements of income. SBA servicing fees totaled $462,000 and $938,000 for the three and six months ended June 30, 2018, respectively. SBA servicing fees totaled $407,000 and $840,000 for the three and six months ended June 30, 2017, respectively. At June 30, 2018 and December 31, 2017, the Company serviced SBA loans for others with unpaid principal balances totaling $184.8 million and $185.6 million, respectively.

The fair value of the SBA servicing rights asset, key metrics, and the sensitivity of the fair value due to adverse changes in key economic assumptions at the periods presented are as follows (dollars in thousands):

Weighted average remaining life (years)	5.9				6.7

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. As indicated, changes in fair value based on adverse changes in model inputs and/or assumptions generally cannot be extrapolated because the relationship of the change in input or assumption to the change in fair value may not be linear. In addition, the effect of an adverse variation in a particular input or assumption on the value of the SBA servicing rights is calculated without changing any other input or assumption. In reality, changes in one factor may magnify or counteract the effect of the change.

The risk inherent in the SBA servicing rights asset includes prepayments at different rates than anticipated or resolution of loans at dates not consistent with the estimated expected lives. These events would cause the value of the servicing asset to decline at a faster or slower rate than originally anticipated.

NOTE 8: DERIVATIVE 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.

Credit and Collateral Risks for Interest Rate Swaps and Caps

The Company manages credit exposure on interest rate swap and cap transactions by entering into a bilateral credit support agreement with each counterparty. The credit support agreements require collateralization of exposures beyond specified minimum threshold amounts. The details of these agreements, including the minimum thresholds, vary by counterparty. Refer to Note 9, 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 June 30, 2018, the Company had no derivatives in a net liability position under these agreements.

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.

STATE BANK FINANCIAL CORPORATION AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

Derivatives Designated as Hedging Instruments

Fair Value Hedges

The Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps, designated as fair value hedges, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments over the life of the agreements without the exchange of the underlying notional amount. The gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. At June 30, 2018 and December 31, 2017, the Company had 72 and 84 interest rate swaps with an aggregate notional amount of $123.0 million and $141.9 million, designated as fair value hedges associated with the Company's fixed rate loan program.

The tables below presents the effect of fair value hedges on the consolidated statements of financial condition for the periods presented (dollars in thousands):

Line Item in the Statement of Financial Condition in Which the Hedged Item Is Included	Carrying Amount of the Hedged Asset				Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Asset
	June 30, 2018		December 31, 2017		June 30, 2018			December 31, 2017
Loans	$	119,559	$	139,391	$	(4,145	)	$	(1,892	)
Total	$	119,559	$	139,391	$	(4,145	)	$	(1,892	)

Cash Flow Hedges

The Company used 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 former cash flow hedges were for the purpose of capping interest rates paid on deposits, which protected 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. These caps expired in the first quarter of 2018. Amounts reported in AOCI related to derivatives were reclassified to interest expense as the interest rate cap premium was amortized over the life of the cap.

(1) The application of collateral cannot reduce the net amount below zero; therefore, excess collateral received/posted is not reflected in this table. All positions are fully collateralized.

Repurchase Agreements

The Company utilizes securities sold under repurchase agreements to facilitate the needs of its customers. Securities sold under repurchase agreements consist of balances in the transaction accounts of commercial customers swept nightly to an overnight investment account and are collateralized with investment securities having a market value no less than the balance borrowed. The investment securities pledged are subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below the balance of the repurchase agreements on a daily basis and may be required to provide additional collateral. Securities pledged as collateral are maintained with a safekeeping agent.

At June 30, 2018 and December 31, 2017, securities sold under repurchase agreements were $13.5 million and $25.2 million, respectively, all of which mature on an overnight and continuous basis. At both June 30, 2018 and December 31, 2017, investment securities pledged for the outstanding repurchase agreements consisted of U.S. government sponsored agency mortgage-backed securities.

NOTE 10: REGULATORY MATTERS

Regulatory Capital Requirements

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.

Beginning on January 1, 2016, the Company and State Bank must maintain a capital conservation buffer to avoid restrictions on capital distributions or discretionary bonus payments. This buffer must consist solely of Common Equity Tier 1 Capital, but the buffer applies to all three measurements (Common Equity Tier 1, Tier 1 capital and total capital) in addition to the minimum risk-based capital requirements. The capital conservation buffer required for 2018 is common equity equal to 1.875% of risk-weighted assets and will increase by .625% per year until reaching 2.5% beginning January 1, 2019.

The minimum regulatory capital ratios and ratios to be considered well-capitalized under prompt corrective action provisions at both June 30, 2018 and December 31, 2017 are presented in the table below:

Capital Ratio Requirements	Minimum Requirement	Well-capitalized (1)
Common Equity Tier 1 (CET1) capital ratio	4.50%	6.50%
Tier 1 risk-based capital ratio	6.00%	8.00%
Total risk-based capital ratio	8.00%	10.00%
Tier 1 leverage ratio	4.00%	5.00%

(1) The prompt corrective action provisions are only applicable at the bank level.

At June 30, 2018 and December 31, 2017, the Company and State Bank exceeded all regulatory capital adequacy requirements to which they were subject.

Regulatory Restrictions on Dividends

Regulatory policy statements provide that generally bank holding companies should pay dividends only out of current operating earnings and that the level of dividends must be consistent with current and expected capital requirements. Dividends received from State Bank have been the primary source of funds available for the declaration and payment of dividends to the Company's common shareholders.

Federal and state banking laws and regulations restrict the amount of dividends banks may distribute without prior regulatory approval. At June 30, 2018, State Bank had no capacity to pay dividends to the Company without prior regulatory approval.

At June 30, 2018, the Company had $66.5 million in cash and due from bank accounts, which can be used for additional capital as needed by State Bank, payment of holding company expenses, payment of dividends to shareholders, or for other corporate purposes.

NOTE 11: COMMITMENTS AND CONTINGENT LIABILITIES

Commitments

In order to meet the financing needs of its customers, the Company maintains financial instruments with off-balance-sheet risk in the normal course of business. These financial instruments include commitments to extend credit and standby letters of credit and involve, to varying degrees, elements of credit, interest rate and/or liquidity risk. Such financial instruments are recorded when they are funded and the related fees are generally recognized when collected.

Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed maturity dates or other termination clauses with required fee payments. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The amount of collateral required, if deemed necessary upon extension of credit, is determined on a case by case basis by management through credit evaluation of the customer.

Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those guarantees are issued primarily to support public and private borrowing arrangements. In order to minimize its exposure, the Company's credit policies govern the issuance of standby letters of credit.

The Company's exposure to credit loss is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments.

A summary of the Company's commitments is as follows (dollars in thousands):

	June 30, 2018		December 31, 2017
Commitments to extend credit:
Fixed	$	91,509	$	65,117
Variable	944,668		914,524
Letters of credit:
Fixed	5,759		5,978
Variable	6,895		11,428
Total commitments	$	1,048,831	$	997,047

The fixed rate loan commitments have maturities ranging from one month to thirteen years. Management takes appropriate actions to mitigate interest rate risk associated with these fixed rate commitments through various measures including, but not limited to, the use of derivative financial instruments.

Contingent Liabilities

Mortgage loan sales agreements contain covenants that may, in limited circumstances, require the Company to repurchase or indemnify the investors for losses or costs related to the loans the Company has sold. As a result of the potential recourse provisions, the Company maintains a recourse liability for mortgage loans sold to investors. At June 30, 2018, the recourse liability was $296,000.

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.

NOTE 12: 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The Company evaluates fair value measurement inputs on an ongoing basis in order to determine if there is a change of sufficient significance to warrant a transfer between levels. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company's valuation process. For the six months endedJune 30, 2018 and the year ended December 31, 2017, there were no transfers between levels.

Fair Value Option

ASC 820 allows companies to report selected financial assets and liabilities at fair value using the fair value option. The changes in fair value are recognized in earnings and the assets and liabilities measured under this methodology are required to be displayed separately on the balance sheet. The Company made the election to record mortgage loans held-for-sale at fair value under the fair value option, which allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to hedge them without the burden of complying with the requirements for hedge accounting.

Financial Assets and Financial Liabilities Measured on a Recurring Basis

The Company uses the following methods and assumptions in estimating the fair value of its financial assets and financial liabilities on a recurring basis:

Investment Securities Available-for-Sale

At June 30, 2018, 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.

Hedged Loans

Loans involved in fair value hedges are recorded at fair value on a recurring basis. The estimated fair value is determined using Level 2 inputs consistent with the valuation methodology for interest rate swaps discussed below. The Company does not record other loans held for investment at fair value on a recurring basis.

Mortgage Loans Held-for-Sale

Mortgage loans held-for-sale are recorded at fair value on a recurring basis. The estimated fair value is determined using Level 2 inputs based on observable data such as the existing forward commitment terms or the current market value of similar loans. Interest income is recorded in interest income on the consolidated statements of income and is based on the contractual terms of the loan. None of these loans were 90 days or more past due or on nonaccrual at June 30, 2018.

46

STATE BANK FINANCIAL CORPORATION AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

At June 30, 2018, the aggregate fair value of the Company's mortgage loans held-for-sale was $39.2 million and the contractual balance including accrued interest was $38.1 million, with a fair value mark totaling $1.2 million. The Company recognized a gain of $251,000 and a gain of $617,000 for the three and six months ended June 30, 2018, respectively, related to the change in fair value of the mortgage loans held-for-sale, included in "mortgage banking income" on the consolidated statements of income. For the three and six months ended June 30, 2017, the amount recognized related to the change in fair value of the mortgage loans held-for-sale was a loss of $243,000 and a gain of $482,000, respectively.

Derivative Financial Instruments

Interest Rate Swaps and Caps

The Company uses interest rate swaps to provide longer-term fixed rate funding to its customers and interest rate caps to mitigate the interest rate risk on its variable rate liabilities. The majority of these derivatives are traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract. Therefore, these derivative contracts are classified as Level 2. The Company utilizes an independent third party valuation company to validate the dealer prices. In cases where significant credit valuation adjustments are incorporated into the estimation of fair value, reported amounts are considered to have been derived utilizing Level 3 inputs.

The Company evaluates the credit risk of its counterparties as well as that of the Company. The Company has considered factors such as the likelihood of default by the Company and its counterparties, its net exposures, and remaining contractual life, among other things, in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting arrangements, as well as considering the amount of collateral securing the position. The Company reviews its counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken to adjust the exposure. The Company also utilizes this approach to estimate its own credit risk on derivative liability positions. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position.

Mortgage Derivatives

Mortgage derivatives include interest rate lock commitments to originate residential mortgage loans held-for-sale. The Company relies on an internal valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held-for-sale. The model groups the interest rate lock commitments by interest rate and term, applies an estimated pull-through rate based on historical experience, and then multiplies by quoted investor prices which were determined to be reasonably applicable to the loan commitment group based on interest rate, term, and rate lock expiration date of the loan commitment group. While there are Level 2 and 3 inputs used in the valuation model, the Company has determined that the majority of the inputs significant in the valuation of the interest rate lock commitments fall within Level 3 of the fair value hierarchy. Changes in the fair values of these derivatives are included in "mortgage banking income" on the consolidated statements of income.

Mortgage derivatives also include forward commitments to sell residential mortgage loans to various investors when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitment to fund loans. The Company also relies on an internal valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e., an estimate of what the Company would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available (Level 2). Changes in the fair values of these derivatives are included in "mortgage banking income" on the consolidated statements of income.

SBA Servicing Rights

The Company has the rights to service a portfolio of SBA loans. The SBA servicing rights are measured at fair value when loans are sold on a servicing retained basis. The servicing rights are subsequently measured at fair value on a recurring basis utilizing Level 3 inputs. Management uses a model operated and maintained by a third party to calculate the present value of future cash flows using the third party's market-based assumptions. The future cash flows for each asset are based on the asset's unique characteristics and the third party's market-based assumptions for prepayment speeds, default and voluntary prepayments. For non-guaranteed portions of servicing assets, future cash flows are estimated using loan specific assumptions for losses and recoveries. Adjustments to fair value are recorded as a component of "SBA income" on the consolidated statements of income. Please reference Note 7 for the roll-forward of the SBA servicing rights asset at fair value utilizing level 3 inputs.

The following tables present financial assets and financial liabilities measured at fair value on a recurring basis at the dates indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Financial Assets Measured on a Nonrecurring Basis

The Company uses the following methods and assumptions in estimating the fair value of its financial assets on a nonrecurring basis:

Impaired Loans

Loans, excluding purchased credit impaired loans, are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The fair values of impaired loans are measured on a nonrecurring basis and are based on the underlying collateral value of each loan if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs that are based on observable market data such as an appraisal. Updated appraisals are obtained on at least an annual basis. Level 3 inputs are based on the Company's customized discounting criteria when management determines the fair value of the collateral is further impaired.

The following table presents financial assets measured at fair value on a nonrecurring basis at the dates indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

	Quoted Market Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total

Total nonrecurring assets at fair value	$	—	$	—	$	11,804	$	11,804

Impaired loans, excluding purchased credit impaired loans, that are measured for impairment using the fair value of collateral for collateral dependent loans had recorded investments of $70.9 million and $13.0 million with respective valuation allowances of $1.9 million and $1.2 million at June 30, 2018 and December 31, 2017, 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.

NOTE 13: 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. There were no anti-dilutive securities excluded from the computation of earnings per share in the periods presented.

Earnings per share have been computed based on the following weighted average number of common shares outstanding (dollars in thousands, except per share data):

Item 2.  Management's Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion analyzes our consolidated financial condition at June 30, 2018 as compared to December 31, 2017 and our results of operations for the three and six months ended June 30, 2018 as compared to the three and six months ended June 30, 2017. This discussion should be read in conjunction with our consolidated financial statements and accompanying footnotes appearing in this report and in conjunction with the financial statements and related notes in our 2017 Annual Report on Form 10-K. 

We have made, and will continue to make, various forward-looking statements with respect to financial and business matters. Comments regarding our business that are not historical facts are considered forward-looking statements, which involve inherent risks and uncertainties. Actual results may differ materially from those contained in these forward-looking statements. For additional information regarding our cautionary disclosures, see the "Cautionary Note Regarding Forward-Looking Statements" beginning on page 1 of this report.

Business Overview

The Company is a bank holding company that was incorporated under the laws of the State of Georgia in January 2010 to serve as the holding company for State Bank and Trust Company ("State Bank"). State Bank is a Georgia state-chartered bank that opened in October 2005. Between July 24, 2009 and June 30, 2018, we successfully completed 17 bank acquisitions totaling $6.0 billion in assets and $5.2 billion in deposits.

In this report, unless the context indicates otherwise, all references to "we," "us," and "our" refer to State Bank Financial Corporation and our wholly-owned subsidiary, State Bank.

As a result of our acquisitions, we were transformed from a small community bank to a much larger commercial bank. We are now operating 32 full-service branches throughout seven of Georgia's eight largest metropolitan statistical areas, or MSAs. At June 30, 2018, our total assets were $5.0 billion, our total loans receivable were $3.6 billion, our total deposits were $4.3 billion and our total shareholders' equity was $656.9 million.

Recent Developments

Proposed Merger with Cadence Bancorporation

On May 11, 2018, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Cadence Bancorporation, a Delaware corporation ("Cadence"). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, the Company will merge with and into Cadence, with Cadence continuing as the surviving corporation. Immediately following the completion of the merger, the Bank will merge with and into Cadence’s wholly owned bank subsidiary, Cadence Bank, N.A. ("Cadence Bank"), with Cadence Bank continuing as the surviving bank. Subject to the terms and conditions of the Merger Agreement, if the merger is completed, Company shareholders will receive 1.160 shares of Cadence Class A common stock, par value $0.01 per share, for each share of Company common stock, par value $0.01 per share, they hold immediately prior to the merger, plus cash in lieu of fractional shares.

The transaction is expected to close in the fourth quarter of 2018, subject to Company shareholder and regulatory approvals in addition to satisfaction of certain other closing conditions.

Acquisition of AloStar Bank of Commerce

On September 30, 2017, State Bank completed its acquisition of AloStar Bank of Commerce ("AloStar"), an Alabama banking corporation. State Bank Interim Corp., a wholly-owned subsidiary of State Bank, merged with and into AloStar with AloStar as the surviving bank and immediately thereafter, AloStar merged with and into State Bank, with State Bank as the surviving bank. We paid total cash consideration of approximately $195.0 million for all outstanding shares of AloStar. With the acquisition of AloStar, we acquired banking operations in Birmingham, Alabama and Atlanta, Georgia. Banking operations in Birmingham were closed on January 31, 2018.

Quarterly Highlights

The following provides an overview of the major factors impacting our financial performance for the quarter ended June 30, 2018:

• Net income for the quarter ended June 30, 2018 was $18.8 million, or $.48 per diluted share, compared to net income of $15.2 million, or $.39 per diluted share, for the quarter ended June 30, 2017.

• Our net interest income on a taxable equivalent basis was $56.1 million for the quarter ended June 30, 2018, an increase of $9.5 million, or 20.4%, from the quarter ended June 30, 2017. Our interest income increased$13.7 million for the quarter ended June 30, 2018, compared to the quarter ended June 30, 2017, primarily attributable to a $15.4 millionincrease in loan interest income and a $930,000increase in interest income on invested funds, partially offset by a $2.6 milliondecline in accretion income on loans primarily due to lower recovery income.

• We continued to benefit from the strong loan growth of the first quarter of 2018. At June 30, 2018, total loans were $3.6 billion, an increase of $73.1 million, or 2.1%, from December 31, 2017. During the quarter ended June 30, 2018, loan balances contracted slightly as decreases in our purchased credit impaired and purchased non-credit impaired loans offset organic loan growth.

• The accretable discount on purchased credit impaired loansdecreased$4.4 millionto$53.5 millionatJune 30, 2018, compared to$57.9 millionatDecember 31, 2017. We recognized$12.5 million in accretion income on purchased credit impaired loans during the six months ended June 30, 2018, offset by transfers from nonaccretable to accretable discount of $8.2 million.

• Asset quality remained sound atJune 30, 2018with annualized net charge-offs of.06%for thesix months ended June 30, 2018.

• The average cost of funds increased33 basis points to 71 basis points for the quarter ended June 30, 2018, compared to the same period in 2017, primarily due to an increase in the balance and rate on money market deposits, as well as time deposits acquired from AloStar during 2017. This compares favorably to the 75 basis point increase in the Federal Funds target rate over the same period.

• The Company's capital ratios exceeded all regulatory "well capitalized" guidelines, with a Tier 1 leverage ratio of 11.75%, CET1 and Tier 1 risk-based capital ratios of 12.79%, and a Total risk-based capital ratio of 13.53% at June 30, 2018.

• During the second quarter of 2018, we declared and paid a cash dividend of $0.20 per common share to our shareholders.

GAAP Reconciliation and Management Explanation of Non-GAAP Financial Measures

Certain financial measures included in this report, tangible book value per common share and average tangible equity, are financial measures that are not recognized by generally accepted accounting principles in the United States, or GAAP. These non-GAAP financial measures exclude the effect of the period end or average balance of intangible assets. Management believes that these non-GAAP financial measures provides additional useful information to investors, particularly since these measure are widely used by industry analysts for companies with prior merger and acquisition activities, such as us.

A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measure is presented in the accompanying table. Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied, and are not audited. These non-GAAP financial measures should not be considered as a substitute for GAAP financial measures, and we strongly encourage investors to review the GAAP financial measures included in this report and not to place undue reliance upon any single financial measure. In addition, because non-GAAP financial measures are not standardized, it may not be possible to compare the non-GAAP financial measures presented in this report with other companies’ non-GAAP financial measures having the same or similar names.

Results of Operations

Net Income

We reported net income of $18.8 million and $36.1 million for the three and six months ended June 30, 2018, respectively, compared to net income of $15.2 million and $26.8 million for the same periods in 2017. Diluted earnings per common share were $.48 and $.92 for the three and six months ended June 30, 2018, respectively, compared to diluted earnings per common share of $.39 and $.69 for the same periods in 2017.

Net Interest Income (Taxable Equivalent)

       Net interest income, which is our primary source of earnings, is the difference between interest earned on interest-earning assets, as well as accretion income on purchased credit impaired loans and interest incurred on interest-bearing liabilities. Net interest income depends upon the relative mix of interest-earning assets and interest-bearing liabilities, the ratio of interest-earning assets to total assets and of interest-bearing liabilities to total funding sources, and movements in market interest rates.

Three Months Ended June 30, 2018 and 2017

Our net interest income on a taxable equivalent basis was $56.1 million for the three months ended June 30, 2018, an increase of $9.5 million, or 20.4%, from the three months ended June 30, 2017. This increase was primarily attributable to an increase in average loans, excluding purchased credit impaired loans, of $744.6 million compared to the three months ended June 30, 2017. An increase in average interest bearing deposits of $609.5 million, compared to the three months ended June 30, 2017, partially offset the impact of the increases in average loans, excluding purchased credit impaired loans.

Our net interest spread on a taxable equivalent basis, which is the difference between the yields earned on average earning assets and the rates paid on average interest-bearing liabilities, was 4.49% for the three months ended June 30, 2018, compared to 4.58% for the same period in 2017, a decrease of nine basis points. Our net interest margin on a taxable equivalent basis, which is net interest income divided by average interest-earning assets, was 4.82% for the three months ended June 30, 2018 compared to 4.76% for the same period in 2017, an increase of six basis points.

The yield on average earning assets was 5.47% for the three months ended June 30, 2018, compared to 5.11% for the three months ended June 30, 2017, an increase of 36 basis points, driven primarily by an increase in the yield on loans, excluding purchased credit impaired loans, and investment securities, partially offset by a decrease in the yield on purchased credit impaired loans. The yield on our purchased credit impaired loans can vary significantly from period to period depending largely on the timing of loan pool closings for our purchased credit impaired loans that are accounted for in pools, recoveries received on purchased credit impaired loans and the timing of customer payments. The decrease of 887 basis points in our yield on purchased credit impaired loans was primarily due to a decrease in loan recovery income of $2.0 million in the second quarter of 2018 compared to the same period in 2017, as well as the lower yield on the purchased credit impaired portfolios acquired in our recent acquisitions. Our yield on loans, excluding purchased credit impaired loans, was 5.77% for the three months ended June 30, 2018, compared to 5.08% for the same period in 2017, an increase of 69 basis points. The increase primarily resulted from a combination of higher rates on new loan originations and variable rate loans repricing at higher rates due to increases in index rates. The yield on our investment portfolio was 2.86% and 2.39% for the three months ended June 30, 2018 and 2017, respectively. The increase of 47 basis points compared to the prior period was primarily driven by variable rate securities repricing at higher rates due to increases in index rates and the reinvestment of some cash flows from securities into higher yielding bonds as market rates have increased.

The average rate on interest-bearing liabilities was .98% for the three months ended June 30, 2018, an increase of 45 basis points from the same period in 2017. The average rate paid on interest-bearing deposits was .96% and .51% for the three months ended June 30, 2018 and 2017, respectively. The increase of 45 basis points was primarily the result of an increase in the rate paid on savings and money market accounts, the assumption of higher-yielding internet time deposits in our acquisition of AloStar and a shift in the mix of interest-bearing deposits to time deposits. Also contributing to the increase in the rate paid on interest-bearing liabilities was a 77 basis point increase in the rate paid on other borrowings compared to the same period in 2017. Our cost of funds was 71 basis points for the three months ended June 30, 2018, an increase of 33 basis points from the same period in 2017.

Six Months Ended June 30, 2018 and 2017

Our net interest income on a taxable equivalent basis was $111.0 million for the six months ended June 30, 2018, an increase of $20.3 million, or 22.4%, from the six months ended June 30, 2017. This increase was primarily attributable to an

61

increase in average loans, excluding purchased credit impaired loans, of $742.2 million compared to the six months ended June 30, 2017. An increase in average interest bearing deposits of $572.1 million, compared to the six months ended June 30, 2017, partially offset the impact of the increases in average loans, excluding purchased credit impaired loans.

Our net interest spread on a taxable equivalent basis, which is the difference between the yields earned on average earning assets and the rates paid on average interest-bearing liabilities, was 4.55% for the six months ended June 30, 2018, compared to 4.50% for the same period in 2017, an increase of five basis points. Our net interest margin on a taxable equivalent basis, which is net interest income divided by average interest-earning assets, was 4.84% for the six months ended June 30, 2018 compared to 4.68% for the same period in 2017, an increase of 16 basis points.

The yield on average earning assets was 5.41% for the six months ended June 30, 2018, compared to 5.02% for the six months ended June 30, 2017, an increase of 39 basis points, driven primarily by an increase in the yield on loans, excluding purchased credit impaired loans, and investment securities, partially offset by a decrease in the yield on purchased credit impaired loans. The yield on our purchased credit impaired loans can vary significantly from period to period depending largely on the timing of loan pool closings for our purchased credit impaired loans that are accounted for in pools, recoveries received on purchased credit impaired loans and the timing of customer payments. The decrease of 731 basis points in our yield on purchased credit impaired loans was primarily due to a decrease in loan recovery income of $3.3 million for the six months ended June 30, 2018, compared to the same period in 2017, as well as the lower yield on the purchased credit impaired portfolios acquired in our recent acquisitions. Our yield on loans, excluding purchased credit impaired loans, was 5.75% for the six months ended June 30, 2018, compared to 5.12% for the same period in 2017, an increase of 63 basis points. The increase primarily resulted from a combination of higher rates on new loan originations and variable rate loans repricing at higher rates due to increases in index rates. The yield on our investment portfolio was 2.79% and 2.33% for the six months ended June 30, 2018 and 2017, respectively. The increase of 46 basis points compared to the prior period was primarily driven by variable rate securities repricing at higher rates due to increases in index rates and the reinvestment of some cash flows from securities into higher yielding bonds as market rates have increased.

The average rate on interest-bearing liabilities was .86% for the six months ended June 30, 2018, an increase of 34 basis points from the same period in 2017. The average rate paid on interest-bearing deposits was .85% and .51% for the six months ended June 30, 2018 and 2017, respectively. The increase of 34 basis points was primarily the result of an increase in the rate paid on savings and money market accounts, the assumption of higher-yielding internet time deposits in our acquisition of AloStar and a shift in the mix of interest-bearing deposits to time deposits. Also contributing to the increase in the rate paid on interest-bearing liabilities was a 66 basis point increase in the rate paid on other borrowings compared to the same period in 2017. Our cost of funds was 63 basis points for the six months ended June 30, 2018, an increase of 25 basis points from the same period in 2017.

Rate/Volume Analysis on a Taxable Equivalent Basis

Net interest income can be analyzed in terms of the impact of changing interest rates and changing volumes. The following table reflects the effect that varying levels of interest-earning assets and interest-bearing liabilities and the applicable rates have had on changes in net interest income for the periods presented (dollars in thousands):

	Three Months Ended									Six Months Ended

Provision for Loan and Lease Losses

The provision for loan and lease losses is the amount of expense that, based on our judgment, is required to maintain the allowance for loan and lease losses (ALLL) at an adequate level to absorb probable losses inherent in the loan portfolio at the balance sheet date and that, in management's judgment, is appropriate under U.S. generally accepted accounting principles. The determination of the amount of the ALLL is complex and involves a high degree of judgment and subjectivity. Our determination of the amount of the ALLL and corresponding provision for loan and lease losses considers ongoing evaluations of the credit quality and level of credit risk inherent in various segments of the loan portfolio, levels of nonperforming loans and charge-offs, statistical trends and economic and other relevant factors. Please see the discussion below entitled "Allowance for Loan and Lease Losses (ALLL)" under "Balance Sheet Review" for a description of the factors we consider in determining the amount of periodic provision expense to maintain this allowance.

Organic Loans

For the three months ended June 30, 2018 and 2017, we recorded a provision for loan and lease losses related to organic loans of $1.6 million and $1.1 million, respectively. For the six months ended June 30, 2018 and 2017, we recorded provisions of $3.0 million and $2.4 million, respectively. The amount of provision for loan and lease losses recorded for organic loans was the amount required such that the total allowance for loan and lease losses reflected the appropriate balance, in management’s opinion, to sufficiently cover probable losses in the organic loan portfolio. This determination includes, but is not limited to, factors such as loan growth, asset quality, changes in loan portfolio composition, and national and local economic conditions.

65

Purchased Non-Credit Impaired Loans

We did not record an ALLL at acquisition for our purchased non-credit impaired loans because the loans were recorded at fair value based on a discounted cash flow methodology at the date of each respective acquisition. Subsequent to the purchase date, the ALLL for purchased non-credit impaired loans is evaluated quarterly similar to the method described above for organic loans, and if necessary, additional reserves are recognized in the ALLL. We recorded a provision for loan and lease losses related to purchased non-credit impaired loans of $1.0 million for the three months ended June 30, 2018, compared to $372,000 for the three months ended June 30, 2017. We recorded a provision of $2.2 million and $471,000 for the six months ended June 30, 2018 and 2017, respectively.

Purchased Credit Impaired Loans

Similar to our purchased non-credit impaired loans, we did not record an ALLL at acquisition for our purchased credit impaired loans as the loans were recorded at fair valued based on a discounted cash flow methodology at the date of each respective acquisition. We re-estimate expected cash flows on our purchased credit impaired loans on a quarterly basis. 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 ALLL. Subsequent significant increases in the amount of cash expected to be collected from the borrower results first in the reversal of any previously-recorded provision for loan and lease losses and related ALLL, and then as a prospective increase in the accretable discount on the purchased credit impaired loans. We recorded a negative provision for loan and lease losses related to purchased credit impaired loans of $163,000 for the three months ended June 30, 2018, compared to a provision for loan and lease losses on such loans of $375,000 for the three months ended June 30, 2017. For the six months ended June 30, 2018 and 2017, we recorded a provision for loan and lease losses of $395,000 and $16,000, respectively.

66

Noninterest Income

Noninterest income for the three months ended June 30, 2018 totaled $10.9 million, compared to $10.5 million for the same period in 2017, an increase of $441,000. For the six months ended June 30, 2018, noninterest income was $21.4 million, compared to $19.9 million for the same period in 2017, an increase of $1.4 million. The following table presents the components of noninterest income for the periods indicated (dollars in thousands):

	Three Months Ended June 30				Six Months Ended June 30
	2018		2017		2018		2017
Service charges on deposits	$	1,462	$	1,471	$	3,087	$	2,938
Mortgage banking income	3,125		3,096		6,050		5,990
SBA income	1,252		1,983		2,444		3,161
Payroll and insurance income	1,608		1,418		3,368		2,913
ATM income	919		864		1,789		1,696
Bank-owned life insurance income	463		465		918		949
Gain on sale of investment securities	250		13		250		25
Other	1,838		1,166		3,472		2,263
Total noninterest income	$	10,917	$	10,476	$	21,378	$	19,935

SBA income decreased$731,000, or 36.9%, for the three months ended June 30, 2018 from the same period in 2017. For the six months endedJune 30, 2018, SBA income decreased$717,000, or 22.7%, compared to the same period in 2017. The decreases for the three and six months endedJune 30, 2018 were primarily attributable to a reduction in gains on sales of loans of $668,000 and $601,000, respectively, compared to the same periods in 2017. The reduction in gains on sales of loans is primarily due to a reduction in the volume of loans sold compared to the same periods in 2017 as many loans are pending sale because the balance has not been fully drawn by the clients. These decreases were partially offset by increases in SBA servicing fees of $55,000 and $98,000 for the three and six months endedJune 30, 2018, compared to the same periods in 2017.

Payroll and insurance income increased$190,000, or 13.4%, for the three months ended June 30, 2018 from the same period in 2017. For the six months endedJune 30, 2018, payroll and insurance income increased $455,000, or 15.6%, compared to the same period in 2017. The increase in both periods was primarily due to an increase in commissions on new insurance policies written.

Other noninterest income increased$672,000, or 57.6%, for the three months ended June 30, 2018, compared to the same period in 2017. For the six months endedJune 30, 2018, other noninterest income increased$1.2 million, or 53.4%, compared to the same period in 2017. The increases in other noninterest income were primarily attributable to $753,000 and $1.4 million in fee income on our asset based lending portfolio for the three and six months endedJune 30, 2018, respectively, that we acquired in our acquisition of AloStar in the third quarter of 2017. The fee income on asset based lending was partially offset by decreases in gains on sale of equipment finance loans of $223,000 and $262,000 for the three and six months endedJune 30, 2018, respectively, compared to the same periods in 2017.

67

Noninterest Expense

Noninterest expense for the three months ended June 30, 2018 totaled $40.0 million, up$8.0 million from the same period in 2017. Noninterest expense for the six months ended June 30, 2018 totaled $79.3 million, up$12.7 million from the same period in 2017.

The following table presents the components of noninterest expense for the periods indicated (dollars in thousands):

	Three Months Ended June 30						Six Months Ended June 30
	2018			2017			2018		2017

Amortization of intangibles	654			697			1,305		1,393
Other	3,952			2,553			7,041		5,056
Total noninterest expense	$	39,983		$	31,997		$	79,251	$	66,562

Salaries and employee benefits expense increased$3.1 million, or 14.6%, and $7.8 million, or 18.2%, for the three and six months endedJune 30, 2018, respectively, from the same periods in 2017. These increases were primarily attributable to $2.6 million and $6.8 million, respectively, related to our acquisition of AloStar.

Data processing expenses increased$314,000, or 13.2%, and $571,000 or 11.4%, for the three and six months endedJune 30, 2018, respectively, from the same periods in 2017. These increases were primarily attributable to data processing expenses that we incurred related to our acquisition of AloStar and continued investments in our technology. Legal and professional fees increased$69,000, or 7.7%, for the three months ended June 30, 2018, from the same period in 2017. For the six months endedJune 30, 2018, legal and professional fees decreased $1.0 million, or 36.9%, from the same period in 2017. The decrease in legal and professional fees for the six months endedJune 30, 2018 is primarily attributable to a support system project which was completed during the first quarter of 2017.

Marketing expenses increased$537,000, or 133.3%, and $298,000, or 27.9%, for the three and six months endedJune 30, 2018, respectively, from the same periods in 2017. The increases were primarily related to the timing of marketing campaigns.

Loan collection costs and OREO activity, which are net of rental fees on OREO properties as well as gains and losses on OREO, increased $97,000 and $1.3 million for the three and six months endedJune 30, 2018, respectively, compared to the same periods in 2017. The increase for the six months ended was attributable to a $1.1 million decrease in gains on sale of OREO, a $101,000 increase in loan collection and OREO expenses, and a $100,000 decrease in rental fees, as compared to the same period in 2017. The decrease in rental fees was primarily due to the sale of two OREO properties during the first quarter of 2017.

Merger-related expenses increased$2.2 million, or 599.2%, and $1.3 million, or 48.3%, for the three and six months endedJune 30, 2018, respectively, compared to the same periods in 2017. Merger-related expenses in 2018 were primarily attributable to our acquisition and integration of AloStar and our proposed merger with Cadence. Merger-related expenses in 2017 were related to our acquisitions and integrations of NBG Bancorp, Inc. and S Bankshares, Inc. These expenses include, among other things, liquidating damages from contract terminations, system conversion costs, severance, and professional fees.

Income Taxes

       Income tax expense is comprised of both state and federal income tax expense. The effective tax rate was 23.9% and 34.2% for the three months ended June 30, 2018 and 2017, respectively. The effective tax rate was 24.0% and 34.7% for the six months ended June 30, 2018 and 2017, respectively. The decrease in the effective tax rate for the three and six months ended June 30, 2018 was due to the reduction in the federal corporate tax rate from 35% to 21% effective January 1, 2018.

Balance Sheet Review

General

At June 30, 2018, we had total assets of approximately $5.0 billion, consisting principally of $2.6 billion in net organic loans, $790.1 million in net purchased non-credit impaired loans, $144.5 million in net purchased credit impaired loans, $853.9 million in investment securities and $238.3 million in cash and cash equivalents. Our liabilities at June 30, 2018 totaled $4.4 billion, consisting principally of $4.3 billion in deposits. At June 30, 2018, our shareholders' equity was $656.9 million.

At December 31, 2017, we had total assets of approximately $5.0 billion, consisting principally of $2.3 billion in net organic loans, $1.0 billion in net purchased non-credit impaired loans, $171.9 million in net purchased credit impaired loans, $906.8 million in investment securities and $230.9 million in cash and cash equivalents. Our liabilities at December 31, 2017 totaled $4.3 billion, consisting principally of $4.2 billion in deposits. At December 31, 2017, our shareholders' equity was $641.6 million.

Investments

Our investment portfolio consists of U.S. Government agency securities, municipal securities, nonagency mortgage-backed securities, U.S. Government sponsored agency mortgage-backed securities, asset-backed securities and corporate bonds. The composition of our portfolio reflects our investment strategy of maintaining an appropriate level of liquidity while providing a relatively stable source of revenue. The portfolio also provides a balance to interest rate risk, while providing a vehicle for the investment of available funds, furnishing liquidity and supplying securities to pledge as required collateral. At June 30, 2018, we had $835.7 million in debt securities available-for-sale representing approximately 16.7% of total assets, compared to $872.5 million, or 17.6% of total assets, at December 31, 2017. The decrease in debt securities available-for-sale of $36.8 million, or 4.2%, from December 31, 2017 to June 30, 2018, was primarily due to cash flows from securities used to fund loan growth during the period. At June 30, 2018 and December 31, 2017, we had $16.7 million and $32.9 million, respectively, in debt securities held-to-maturity.

At June 30, 2018, $66.7 million, or 7.8%, of our debt securities were invested in securities of U.S. Government agencies, compared to $69.6 million, or 7.7%, at December 31, 2017. U.S Government agency securities consist of debt obligations issued by the Government Sponsored Enterprises or collateralized by loans that are guaranteed by the SBA and are, therefore, backed by the full faith and credit of the U.S. Government. At June 30, 2018, $543.0 million, or 63.7%, of our debt securities were invested in agency mortgage-backed securities, compared to $575.8 million, or 63.6%, at December 31, 2017. Agency mortgage-backed securities are securities that have been developed by pooling a number of real estate mortgages and are principally issued by "quasi-federal" agencies such as the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac). The contractual monthly cash flows of principal and interest are guaranteed by the issuing agencies. Although investors generally assume that the federal government will support these agencies, it is under no obligation to do so. Other agency mortgage-backed securities are issued by Government National Mortgage Association (Ginnie Mae), which is a federal agency, and are guaranteed by the U.S. Government. The actual maturities of these mortgage-backed securities will differ from their contractual maturities because the loans underlying the securities can prepay.

At June 30, 2018, $99.2 million, or 11.6%, of our debt securities were invested in nonagency mortgage-backed securities, compared to $118.7 million, or 13.1%, at December 31, 2017. The underlying collateral consists of mortgages originated prior to 2006 with the majority being 2004 and earlier. None of the collateral is sub-prime and we own the senior tranche of each bond.

At June 30, 2018, $16.7 million, or 2.0%, of our debt securities were invested in asset-backed securities, compared to $22.7 million, or 2.5%, at December 31, 2017. Asset-backed securities currently consist of highly-rated collateralized loan obligations. The investment in this asset class was due to management's decision to invest in securities with significant credit support and variable rate structures that could provide higher returns than other variable rate securities without adding significant risk. At June 30, 2018, $126.8 million, or 14.9%, of our debt securities were invested in corporate securities, compared to $118.5 million, or 13.1%, at December 31, 2017. Corporate securities currently consist of short duration debt and longer term financial institution subordinated debt securities. We evaluate and underwrite each issuer prior to purchase and periodically review the issuers after purchase.

Loans

We had total net loans outstanding, including organic and purchased loans, of $3.6 billion and $3.5 billion at June 30, 2018 and December 31, 2017, respectively. Loans secured by real estate, consisting of commercial or residential property, are the principal component of our loan portfolio. Even if the principal purpose of the loan is not to finance real estate, when reasonable, we obtain a security interest in the real estate in addition to any other available collateral to increase the likelihood of ultimate repayment or collection of the loan.

Organic Loans

Organic loans increased$297.9 million, or 12.6%, to $2.7 billion at June 30, 2018 from December 31, 2017. The $297.9 million increase was a result of strong economic conditions and traction in asset generating verticals. Also contributing to organic loan growth was the reclassification of purchased non-credit impaired and purchased credit impaired loans which renewed and met our current underwriting standards for organic loans.

Purchased Loans

Purchased non-credit impaired loans were $793.1 million at June 30, 2018, down$197.6 million, or 19.9%, from December 31, 2017. The decrease in purchased non-credit impaired loans from December 31, 2017 was primarily due to purchased non-credit impaired loans which were paid down or refinanced. Our purchased credit impaired loans decreased$27.2 million, or 15.5%, to $148.5 million at June 30, 2018 from December 31, 2017. Our purchased credit impaired loans decreased due to loans which were paid down or refinanced.

Allowance for Loan and Lease Losses (ALLL)

The ALLL represents the amount that management believes is necessary to absorb probable losses inherent in the loan portfolio at the balance sheet date and involves a high degree of judgment and complexity. The ALLL is critical to the portrayal and understanding of our financial condition, liquidity and results of operations. The determination and application of the ALLL accounting policy involves judgments, estimates and uncertainties that are subject to change. Changes in these assumptions, estimates or the conditions surrounding them may have a material impact on our financial condition, liquidity and results of operations.

At June 30, 2018, our total ALLL for the loan portfolio was $33.3 million, an increase of $4.6 million compared to December 31, 2017. The ALLL reflected $1.0 million of net charge-offs and a $5.6 millionprovision for loan and lease losses on our total loan portfolio for the six months endedJune 30, 2018.

Organic loans

The ALLL on our organic loan portfolio is determined based on factors such as changes in the nature and volume of the portfolio, overall portfolio quality, delinquency trends, adequacy of collateral, loan concentrations, specific problem loans and economic conditions that may affect the borrowers' ability to pay. The ALLL for organic loans consists of two components: a specific reserve and a general reserve. The specific reserve is representative of identified credit exposures that are readily predictable by the current performance of the borrower and the underlying collateral and relates to loans that are individually determined to be impaired. The general reserve is based on historical loss experience adjusted for current economic factors and relates to nonimpaired loans. Historical losses are adjusted by a qualitative analysis that reflects several key economic indicators such as gross domestic product, unemployment and core inflation as well as asset quality trends, rate risk and unusual events or significant changes in personnel, policies and procedures. The qualitative analysis requires judgment by management and is subject to continuous validation.

At June 30, 2018, our organic ALLL increased$2.3 million to $26.4 million, compared to $24.0 million at December 31, 2017. The increase in our organic ALLL at June 30, 2018 is largely from $3.0 million of provision for loan and lease losses charged to expense for the six months endedJune 30, 2018, primarily due to organic loan growth and net charge-offs. Net charge-offs on organic loans for the six months endedJune 30, 2018, decreased $254,000 compared to the same period in 2017.

Purchased loans

We maintain an allowance for loan and lease losses on purchased loans based on credit deterioration after the acquisition date. In accordance with the accounting guidance for business combinations, we recorded no allowance for loan and lease losses on any of our purchased loans at the acquisition date because any credit deterioration evident in the loans was included in the determination of the fair value of the loans.

For 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. For amortizing loans, the discount is accreted to interest income over the life of the loan on an effective yield basis. Purchase discounts on lines of credit accrete on a straight line basis over the life of the loan. After the purchase date, the method used to evaluate the sufficiency of the credit discount is similar to organic loans, and if necessary, additional reserves are recognized in the allowance for loan and lease losses. At June 30, 2018, our purchased non-credit impaired ALLL was $3.0 million, an increase of $2.0 million, compared to December 31, 2017. The increase in the purchased non-credit impaired ALLL was primarily due to lines of credits acquired in our acquisition of AloStar which accreted the discount on a straight line basis while the corresponding balances did not decline proportionately and a specific provision on one purchased non-credit impaired relationship which was downgraded during the quarter.

We determine the ALLL on our purchased credit impaired loan portfolio based on expected future cash flows. On the date of acquisition, management determines which purchased credit impaired loans are placed in homogeneous risk pools or reviewed specifically as part of the periodic cash flow re-estimation process. If a loan is placed in a pool, the overall performance of the pool will determine if any future ALLL is required.

The ALLL analysis on purchased credit impaired loans represents management's estimate of the potential impairment of the acquired loans, or pools of acquired loans, after the original acquisition date. We established the purchased credit impaired ALLL due to additional credit deterioration in our purchased credit impaired loan portfolio after initial fair value estimates. Typically, decreased estimated cash flows result in impairment, while increased estimated cash flows result in a

74

full or partial reversal of previously recorded impairment and potentially the calculation of a higher effective yield. The potentially higher yield is recorded as accretion income on our consolidated statements of income. If actual losses exceed the estimated losses, we record a provision for loan and lease losses on purchased credit impaired loans as an expense on our consolidated statements of income. If actual losses are less than our previously estimated losses, we reduce the purchased credit impaired ALLL by recording a negative provision for loan and lease losses on purchased credit impaired loans up to the amount of the ALLL previously recorded.

At June 30, 2018, our purchased credit impaired ALLL was $4.0 million, compared to $3.7 million at December 31, 2017. The provision for loan and lease losses charged to expense for the six months endedJune 30, 2018 was $395,000, compared to $16,000 for the same period in 2017. The increase in purchased credit impaired ALLL was primarily due to a decline in expected cash flows on a small number of specifically reviewed loans during the period. The overall purchased credit impaired loan portfolio continues to perform better than our initial projections at each applicable acquisition date, although the performance is not uniform across all asset classes within specifically reviewed loans and loan pools.

For organic loans and purchased non-credit impaired loans, the provision for loan and lease losses will be affected by the loss potential on distressed loans and trends in the delinquency of loans, nonperforming loans and net charge-offs, which may be higher than our historical experience. For purchased credit impaired loans, the provision for loan and lease losses will be most significantly influenced by differences in actual credit losses resulting from the resolution of purchased credit impaired loans from the estimated credit losses used in determining the estimated fair values of such purchased credit impaired loans as of their acquisition or re-estimation dates.

Nonperforming assets consist of nonaccrual loans, troubled debt restructurings ("TDRs"), other real estate owned and foreclosed property. For organic and purchased non-credit impaired loans, management continuously monitors loans and transfers loans to nonaccrual status when they are 90 days past due.

77

We do not consider our purchased credit impaired loans acquired with evidence of deteriorated credit quality to be nonperforming assets as long as their cash flows continue to be estimable and probable of collection. Therefore, interest income is recognized through accretion of the difference between the carrying value of these loans and the present value of expected future cash flows. As a result, management has excluded purchased credit impaired loans from the table in this section.

Loans, other than purchased credit impaired loans, that are either (a) $500,000 or greater and that have been placed on nonaccrual, (b) less than $500,000 and 180 days past due or greater that have been placed on nonaccrual or (c) modified in a troubled debt restructuring are considered impaired and are individually evaluated for impairment at either the observable market price of the loan, the present value of expected future cash flows or the fair value of the collateral less estimated costs to sell, if the loan is collateral dependent. The majority of these loans are collateral dependent and, therefore, are valued using the fair value of collateral method. The fair value of collateral is determined through a review of the appraised value and an assessment of the recovery value of the collateral through discounts related to various factors noted below. When a loan reaches nonaccrual status, we review the appraisal on file and determine if the appraisal is current and valid. A current appraisal is one that has been performed in the last twelve months, and a valid appraisal is one that we believe accurately and appropriately addresses current market conditions. If the appraisal is more than twelve months old or if market conditions have deteriorated since the last appraisal, we will order a new appraisal. In addition, we require a new appraisal at the time of foreclosure or repossession of the underlying collateral. Upon determining that an appraisal is both current and valid, management assesses the recovery value of the collateral, which involves the application of various discounts to the market value. These 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.

For nonaccrual organic impaired loans, we will record either a specific allowance or a charge-off against the ALLL if an impairment analysis indicates a collateral deficiency. For nonaccrual purchased non-credit impaired loans, if an impairment analysis indicates a collateral deficiency, a specific allowance or charge-off against the ALLL is recorded only if the collateral deficiency exceeds the fair value mark recognized at acquisition. The ALLL is evaluated at least quarterly to ensure it is sufficient to absorb all estimated credit losses in the loan portfolio given the facts and circumstances as of the evaluation date.

Loans, other than purchased credit impaired loans, that are nonperforming remain on nonaccrual status until the factors that previously indicated doubtful collectability on a timely basis no longer exist. Specifically, we look at the following factors before returning a nonperforming loan to performing status: documented evidence of debt service capacity; adequate collateral; and a minimum of six months of satisfactory payment performance.

Loan modifications on organic and purchased non-credit impaired loans constitute a troubled debt restructuring if we, for economic or legal reasons related to the borrower's financial difficulties, grant a concession to the borrower that we would not otherwise consider. For loans that are considered troubled debt restructurings, we either compute the present value of expected future cash flows discounted at the original loan's effective interest rate or we may measure impairment based on the observable market price of the loan or the fair value of the collateral when the troubled debt restructuring is deemed collateral dependent. We record the difference between the carrying value and fair value of the loan as a charge-off or valuation allowance, as the situation may warrant.

Loan modifications on purchased credit impaired loans accounted for within a pool under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, do not result in the removal of the loan from the pool even if the modification of the loan would otherwise be considered a troubled debt restructuring. At June 30, 2018, we did not have any purchased credit impaired loans classified as troubled debt restructurings.

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 are transferred into OREO at the lower of their 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. Management periodically reviews the carrying value of OREO for impairment and adjusts the values as appropriate through noninterest expense. At June 30, 2018, OREO totaled $5.0 million, an increase of $4.1 million from December 31, 2017. The increase is mainly attributed to OREO acquired through foreclosure of loans receivable totaling $4.8 million.

The following table set forth our nonperforming assets at the dates indicated (dollars in thousands):

	June 30, 2018												December 31, 2017

Nonperforming assets to total loans and other real estate owned	.48		%	3.20		%	.59		%	1.08		%	.31		%	.59		%	.42		%	.39		%

Nonperforming assets, defined as nonaccrual organic and purchased non-credit impaired loans, troubled debt restructurings and other real estate owned, totaled $39.0 million, or 1.08%, of total loans and other real estate owned at June 30, 2018, compared to $13.9 million, or .39%, at December 31, 2017. The $25.0 millionincrease in nonperforming assets is primarily related to $26.2 million in additions to nonaccrual loans and a $2.8 million addition to accruing troubled debt restructurings, respectively, partially offset by paydowns and charge-offs on existing nonperforming assets. The increase in OREO was primarily related to one property which was moved to OREO during the first quarter of 2018.

At June 30, 2018 and December 31, 2017, we did not have any organic or purchased non-credit impaired loans greater than 90 days past due and still accruing interest. At June 30, 2018 and December 31, 2017, a considerable portion of our purchased credit impaired loans were past due, including many that were 90 days or greater past due; however, as noted above, under ASC 310-30, our purchased credit impaired loans are classified as performing, even though they are contractually past due, as long as their cash flows and the timing of such cash flows are estimable and probable of collection.

The amount of interest that would have been recorded on organic and purchased non-credit impaired nonaccrual loans, had the loans not been classified as nonaccrual, totaled approximately $551,000 for the six months endedJune 30, 2018. Interest income recognized on impaired loans totaled $1.0 million during the six months endedJune 30, 2018.

Potential problem loans are organic and purchased non-credit impaired loans which management has serious doubts as to the ability of the borrowers to comply with the present loan repayment terms. Potential problem loans not included in the nonperforming assets table above, consist of accruing, non-TDR organic and purchased non-credit impaired loans rated "Substandard" or "Doubtful," and totaled $29.6 million, or .9%, of total organic and purchased non-credit impaired loans outstanding at June 30, 2018, compared to $13.9 million, or .4%, at December 31, 2017. The increase in potential problem loans from December 31, 2017 is primarily attributable to our asset-based lending. The majority of these loans were individually evaluated at June 30, 2018 for impairment with no resulting allowance for loan and lease loss.

79

Deferred Tax Asset

At June 30, 2018, we had $17.9 million in net deferred tax assets. Deferred tax assets are subject to an evaluation of whether it is more likely than not that they will be realized. In making such judgments, significant weight is given to evidence that can be objectively verified. Although realization is not assured, management believes the recorded deferred tax assets are fully recoverable based on the current forecast of taxable income that is sufficient to realize the net deferred tax assets. If we are unable to demonstrate that we can continue to generate sufficient taxable income in the near future, then we may not be able to conclude it is more likely than not that the benefits of the deferred tax assets will be fully realized and we may be required to recognize a valuation allowance against our deferred tax assets with a corresponding decrease in income.

Deposits

Total deposits at June 30, 2018 were $4.3 billion, an increase of $59.6 million from December 31, 2017. Interest rates paid on specific deposit types are determined based on (a) interest rates offered by competitors, (b) anticipated amount and timing of funding needs, (c) availability and cost of alternative sources of funding, and (d) anticipated future economic conditions and interest rates. We regard our deposits as attractive sources of funding because of their stability and relative cost. Additionally, we regard our deposits as an important part of our overall client relationship, that provide us with opportunities to cross sell other services.

Noninterest-bearing deposits were $1.2 billion at June 30, 2018, representing 27.6% of total deposits. Noninterest-bearing deposits decreased $4.1 million from December 31, 2017 to June 30, 2018, primarily as a result of reductions in correspondent banking client balances of $28.7 million as we exited the clearing business during the first quarter partially offset by growth in certain of our commercial real estate clients. Average noninterest-bearing deposits increased$152.1 million, or 15.8%, for the six months endedJune 30, 2018 compared to the same period in 2017.

Our interest-bearing transaction accounts decreased$13.9 million from December 31, 2017 to June 30, 2018. The decrease was primarily due to a reduction in public fund balances compared to December 31, 2017. Interest-bearing deposits in savings and money market accounts decreased$39.0 million from December 31, 2017, primarily resulting from reductions in balances of a small number of relationships. Time deposits, excluding brokered and wholesale, decreased$16.8 million from December 31, 2017, primarily as a result of a reduction in internet time deposits acquired in our acquisition of AloStar.

The following table shows the composition of deposits at the dates indicated (dollars in thousands):

	June 30, 2018				December 31, 2017
	Amount		% of  Total		Amount		% of  Total

Capital Resources

We believe that our capital base is adequate to support our activities in a safe manner while at the same time attempting to maximize shareholder returns. At June 30, 2018, shareholders' equity was $656.9 million, or 13.1% of total assets, compared to $641.6 million, or 12.9% of total assets, at December 31, 2017. The primary factors affecting changes in shareholders' equity was our net income, offset by dividends declared during the six months endedJune 30, 2018.

Federal regulations impose minimum regulatory capital requirements on all institutions with deposits insured by the FDIC. The Federal Reserve Board imposes similar capital regulations on bank holding companies. On January 1, 2015, the U.S. Basel III final rule replaced the existing Basel I-based approach for calculating risk-weighted assets. Basel III introduced a new minimum ratio of common equity Tier 1 capital (CET1) and raised the minimum ratios for Tier 1 capital, total capital, and Tier 1 leverage. The final rule emphasizes common equity Tier 1 capital and implements strict eligibility criteria for regulatory capital instruments and improves the methodology for calculating risk-weighted assets to enhance risk sensitivity. The methods for calculating the risk-based capital ratios have changed and 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 by 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. In addition, in order to avoid restrictions on capital distributions or discretionary bonus payments to executives, a covered banking organization must maintain a "capital conservation buffer" on top of its minimum risk-based capital requirements. This buffer must consist solely of Tier 1 Common Equity, but the buffer applies to all three measurements (Common Equity Tier 1, Tier 1 capital and total capital). The capital conservation buffer will be phased in incrementally over time, becoming fully effective on January 1, 2019, and will consist of an additional amount of common equity equal to 2.5% of risk-weighted assets. Implementation of the new capital and liquidity standards did not and is not expected to significantly impact the Company or State Bank because our current capital levels materially exceed those required under the new rules.

The minimum regulatory capital ratios and ratios to be considered well-capitalized under prompt corrective action provisions at the both June 30, 2018 and December 31, 2017 are presented in the table below:

Capital Ratio Requirements	Minimum Requirement	Well-capitalized (1)
CET1 capital ratio	4.50%	6.50%
Tier 1 risk-based capital ratio	6.00%	8.00%
Total risk-based capital ratio	8.00%	10.00%
Tier 1 leverage ratio	4.00%	5.00%

(1) The prompt corrective action provisions are only applicable at the bank level.

81

At June 30, 2018 and December 31, 2017, the Company and State Bank exceeded all regulatory capital adequacy requirements to which they were subject. The following table shows the Company's and State Bank's regulatory capital ratios at the dates indicated:

	June 30, 2018		December 31, 2017
Company
Tier 1 leverage ratio	11.75	%	11.24	%
CET1 capital ratio	12.79		12.61
Tier 1 risk-based capital ratio	12.79		12.61
Total risk-based capital ratio	13.53		13.28
State Bank
Tier 1 leverage ratio	10.21	%	9.90	%
CET1 capital ratio	11.13		11.10
Tier 1 risk-based capital ratio	11.13		11.10
Total risk-based capital ratio	11.88		11.77

Regulatory policy statements generally provide that 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 our primary source of funds available for the payment of dividends to our shareholders. Federal and state banking laws and regulations restrict the amount of dividends subsidiary banks may distribute without prior regulatory approval. During the quarter ended June 30, 2018, State Bank declared and paid a $24.0 million dividend to the Company. At June 30, 2018, State Bank had no capacity to pay dividends to the Company without prior regulatory approval.

At June 30, 2018, the Company had $66.5 million in cash and due from bank accounts, which could be used for additional capital as needed by State Bank, payment of holding company expenses, payment of dividends to shareholders, or for other corporate purposes.

Off-Balance Sheet Arrangements

       Commitments to extend credit are agreements to lend to a customer as long as the customer has not violated any material condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee by the borrower. At June 30, 2018, unfunded commitments to extend credit were $1.0 billion. A significant portion of the unfunded commitments related to commercial and residential real estate construction, commercial lines of credit, including asset based lending and lender finance loans, and consumer equity lines of credit. Based on experience, we anticipate that a significant portion of these lines of credit will not be funded. We evaluate each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by us upon extension of credit, is based on our credit evaluation of the borrower. The type of collateral varies but may include accounts receivable, inventory, property, plant and equipment, and commercial and residential real estate.

       At June 30, 2018, there were commitments totaling approximately $12.7 million under letters of credit. The credit risk and collateral involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Because most of the letters of credit are expected to expire without being drawn upon, they do not necessarily represent future cash requirements.

      Except as disclosed in Note 11 to our consolidated financial statements located in Part I, Item 1 of this Quarterly Report on Form 10-Q, we are not involved in off-balance sheet contractual relationships or commitments, unconsolidated related entities that have off-balance sheet arrangements, or other off-balance sheet transactions that could result in liquidity needs that significantly impact earnings.

82

Contractual Obligations

       In the normal course of business, we have various outstanding contractual obligations that will require future cash outflows. The following table presents our largest contractual obligations (dollarsin thousands):

			Payments Due by Period
June 30, 2018	Total		Less Than 1 Year		1 to 3 Years		3 to 5 Years		More Than 5 Years
Contractual Obligations:
Time deposits, including accrued interest payable	$	857,670	$	635,630	$	208,669	$	13,371	$	—
Operating lease obligations	19,159		4,161		6,666		6,334		1,998
Total contractual obligations	$	876,829	$	639,791	$	215,335	$	19,705	$	1,998

Liquidity

Liquidity represents the ability of a company to convert assets into cash or cash equivalents without significant loss, and the ability to raise additional funds by increasing liabilities. Liquidity management involves monitoring our sources and uses of funds to meet the operating, capital and strategic needs of the Company and State Bank. Liquidity management is made more complicated because different balance sheet components are subject to varying degrees of management control. For example, the timing of maturities of our investment portfolio is fairly predictable and subject to a high degree of control when we make investment decisions. Net deposit inflows and outflows, however, are far less predictable and are not subject to the same degree of certainty.

The asset portion of the balance sheet provides liquidity primarily through scheduled payments, maturities and repayments of loans and investment securities. Cash and short-term investments such as federal funds sold and interest-bearing deposits with other banks are also sources of funding.

At June 30, 2018, our liquid assets, which consist of cash and amounts due from banks, interest-bearing deposits in other financial institutions and federal funds sold, amounted to $238.3 million, or 4.8% of total assets, compared to $230.9 million, or 4.7% of total assets, at December 31, 2017. The decrease in our liquid assets was primarily due to organic loan growth. Our debt securities available-for-sale at June 30, 2018 were $835.7 million, or 16.7% of total assets, compared to $872.5 million, or 17.6% of total assets, at December 31, 2017. Debt securities with an aggregate fair value of $103.9 million and $116.1 million at June 30, 2018 and December 31, 2017, respectively, were pledged to secure public deposits and repurchase agreements. The decrease in our unpledged securities was due to decreases in public funds and repurchase agreements.

The liability portion of the balance sheet serves as our primary source of liquidity. We plan to meet our future cash needs through the generation of deposits. Customer deposits have historically provided a sizeable source of relatively stable and low-cost funds. At June 30, 2018, customer deposits, excluding brokered deposits and time deposits greater than $250,000, were 112.8% of net loans, compared with 116.2% at December 31, 2017. We maintain ten federal funds lines of credit with correspondent banks totaling $200.0 million. We are also a member of the Federal Home Loan Bank of Atlanta (FHLB), from which we can borrow for leverage or liquidity purposes. The FHLB requires that securities and qualifying loans be pledged to secure any advances. At June 30, 2018, we had no advances from the FHLB and a remaining credit availability of $129.6 million. In addition, we maintain a $605.2 million line with the Federal Reserve Bank's discount window that is secured by certain loans from our loan portfolio.

Asset/Liability Management

Market risk is the risk of loss from adverse changes in market prices and rates, which principally arise from interest rate risk inherent in our lending, investing, deposit gathering and borrowing activities. Other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not generally arise in the normal course of our business. Asset/liability management is the process by which we monitor and control the mix and maturities of our assets and liabilities. The essential purposes of asset/liability management are to ensure adequate liquidity and to maintain an appropriate balance between interest sensitive assets and liabilities to minimize potentially adverse effects on earnings from changes in market interest rates. Our Risk Committee monitors and considers methods of managing exposure to interest rate risk and is responsible for maintaining the level of interest rate sensitivity of our interest-sensitive assets and liabilities within Board-approved limits.

83

Interest rate sensitivity is a function of the repricing characteristics of the portfolio of assets and liabilities. Interest rate sensitivity management focuses on the maturity structure of assets and liabilities and their repricing characteristics during periods of changes in market interest rates. Effective interest rate sensitivity management seeks to ensure that both assets and liabilities respond to changes in interest rates within an acceptable time-frame that minimizes the changes in net interest income.

In the event of a shift in interest rates, management may take certain actions intended to mitigate negative impacts on net interest income or to maximize positive impacts on net interest income. These actions may include, but are not limited to, restructuring of interest-earning assets and interest-bearing liabilities, seeking alternative funding sources or investment opportunities, modifying the pricing or terms of loans and deposits, and using derivatives. 

Through the use of derivatives designated as hedging instruments, we seek to efficiently manage the interest rate risk identified in specific assets and liabilities on our balance sheet. At June 30, 2018, we had interest rate swaps with aggregate notional amounts of $123.0 million. The fair value of the derivative financial assets designated as hedging instruments was $4.2 million at June 30, 2018, compared to $2.0 million at December 31, 2017. The fair value of the derivative financial liabilities designated as hedging instruments was $0 at June 30, 2018, compared to $116,000 at December 31, 2017. The change in the values of our derivatives was directly related to changes in the index rates. Note 8 to our consolidated financial statements located in Part I, Item 1 of this Quarterly Report on Form 10-Q provides additional information on these contracts.

We regularly review our exposure to changes in interest rates. Among the factors we consider are changes in the mix of interest-earning assets and interest-bearing liabilities, interest rate spreads and repricing periods. Our Risk Committee reviews, on at least a quarterly basis, our interest rate risk position. The primary tool used to analyze our interest rate risk and interest rate sensitivity is an earnings simulation model.

This earnings simulation model projects a baseline net interest income (assuming no changes in interest rate levels) and estimates changes to that baseline net interest income resulting from changes in interest rate levels. We rely primarily on the results of this model in evaluating our interest rate risk. This model incorporates a number of additional factors including: (1) the expected exercise of call features on various assets and liabilities, (2) the expected rates at which various rate-sensitive assets and rate-sensitive liabilities will reprice, (3) the expected growth in various interest-earning assets and interest-bearing liabilities and the expected interest rates on new assets and liabilities, (4) the expected relative movements in different interest rate indexes which are used as the basis for pricing or repricing various assets and liabilities, (5) existing and expected contractual cap and floor rates on various assets and liabilities, (6) expected changes in administered rates on interest-bearing transaction, savings, money market and time deposit accounts and the expected impact of competition on the pricing or repricing of such accounts, (7) cash flow and accretion expectations from purchased credit impaired loans, and (8) other relevant factors. Inclusion of these factors in the model is intended to more accurately project our expected changes in net interest income resulting from interest rate changes. We typically model our changes in net interest income assuming interest rates go up 100 basis points, up 200 basis points, down 100 basis points and down 200 basis points. We also model more extreme rises in interest rates (e.g. up 500 basis points). For purposes of this model, we have assumed that the changes in interest rates are instantaneously shocked up or down. While we believe this model provides a reasonably accurate projection of our interest rate risk, the model includes a number of assumptions and predictions which may or may not be correct and may impact the model results. These assumptions and predictions include inputs to compute baseline net interest income, growth rates, expected changes in administered rates on interest-bearing deposit accounts, competition and a variety of other factors that are difficult to accurately predict. Accordingly, there can be no assurance the earnings simulation model will accurately reflect future results.

84

The following table presents the earnings simulation model's projected impact of a change in interest rates on the projected baseline net interest income for the 12-month period commencing July 1, 2018. Based on the simulation run at June 30, 2018, annual net interest income would be expected to increase approximately 5.87%, if rates increased from current rates by 100 basis points. If rates increased 200 basis points from current rates, net interest income is projected to increase approximately 11.53%. If rates decreased 100 basis points from current rates, net interest income is projected to decrease approximately 6.50%. The change in interest rates assumes parallel shifts in the yield curve and does not take into account changes in the slope of the yield curve. The small changes in asset sensitivity at June 30, 2018 were primarily due to changes in our deposit mix as low beta deposits grew during the quarter.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

The information required by Item 305 of Regulation S-K is contained in the Management's Discussion and Analysis of Financial Condition and Results of Operations section of this Quarterly Report on Form 10-Q under the heading "Asset/Liability Management," which information is incorporated herein by reference.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures 

Based on management's evaluation, with the participation of the Chief Executive Officer and Chief Financial Officer, as of June 30, 2018, the end of the period covered by this report, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the "Exchange Act")) were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls 

There has been no change in our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any system will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

PART II

Item 1. Legal Proceedings.

In the ordinary course of operations, we may be party to various legal proceedings from time to time. We do not believe that there are any pending or threatened proceedings against us, which, if determined adversely, would have a material effect on our business, results of operations or financial condition.

Item 1A. Risk Factors.

Except as described below, there have been no material changes to the risk factors disclosed in Item 1A. of Part I in our Annual Report on Form 10-K for the year ended December 31, 2017.

Risks Related to Our Proposed Merger with Cadence Bancorporation

We will be subject to business uncertainties and contractual restrictions while the merger with Cadence is pending.

Uncertainty about the effect of the proposed merger with Cadence (which we refer to herein as, the “merger”) on employees and customers may have an adverse effect on the Company. These uncertainties may impair our ability to attract, retain, and motivate key personnel until the merger is completed, and could cause customers and others that deal with us to seek to change existing business relationships. Retention of certain of our employees may be challenging while the merger is pending, as certain employees may experience uncertainty about their future roles with the combined company. If key employees depart because of issues relating to the uncertainty and difficulty of integration, or a desire not to remain with the business, our business could be harmed. In addition, subject to certain exceptions, we have each agreed to operate our business in the ordinary course and use commercially reasonable efforts to preserve our business organization, employees and advantageous business relationships prior to closing. These restrictions may prevent us from pursuing attractive business opportunities that may arise prior to the completion of the merger.

The Merger Agreement limits our ability to pursue acquisition proposals and requires us to pay a termination fee of $37.5 million under limited circumstances, including circumstances relating to acquisition proposals.

The Merger Agreement prohibits us from initiating, soliciting, knowingly encouraging, or knowingly facilitating certain third-party acquisition proposals. The Merger Agreement also provides that we will be required to pay a termination fee in the amount of $37.5 million in the event that the Merger Agreement is terminated under certain circumstances, including an adverse recommendation change of our board of directors. These provisions might discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of the Company from considering or proposing such an acquisition.

If the merger is not completed, we will have incurred substantial expenses without realizing the expected benefits of the merger.

We have incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the Merger Agreement. If the merger is not completed, we would have to recognize these expenses without realizing the expected benefits of the merger.

Regulatory approvals may not be received, may take longer than expected, or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the merger.

Before the merger and before the merger of State Bank with and into Cadence Bank N.A. (which we refer to as the “bank merger”) may be completed, Cadence and the Company must obtain all necessary approvals or waivers from the Federal Reserve Board, the Office of the Comptroller of the Currency and the Georgia Department of Banking and Finance. Other approvals, waivers or consents from regulators may also be required. In determining whether to grant these approvals the regulators consider a variety of factors, including the regulatory standing of each party. An adverse development in either party’s regulatory standing or these factors could result in an inability to obtain approval or delay their receipt. These regulators may impose conditions on the completion of the merger or the bank merger or require changes to the terms of the merger or the bank merger. Such conditions or changes could have the effect of delaying or preventing completion of the merger or the bank merger or imposing additional costs on or limiting the revenues of the combined company following the merger and the bank merger, any of which might have an adverse effect on the combined company following the merger.

86

The Federal Reserve Board has stated that if material weaknesses are identified by examiners before a banking organization applies to engage in expansionary activity, the Federal Reserve Board will not in the future allow the application to remain pending while the banking organization addresses its weaknesses. The Federal Reserve Board explained that, in the future, if issues arise during the processing of an application, it will require the applicant banking organization to withdraw its application pending resolution of any supervisory concerns. Accordingly, if there is an adverse development in either party’s regulatory standing, Cadence may be required to withdraw some or all of the applications for approval of the proposed mergers and, if possible, resubmit it after the applicable supervisory concerns have been resolved.

Termination of the Merger Agreement could negatively impact the Company.

If the Merger Agreement with Cadence is terminated, there may be various consequences. For example, our business may be impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. Additionally, if the Merger Agreement is terminated, the market price of our common stock could decline to the extent that the current market prices reflect a market assumption that the merger will be completed. If the merger agreement is terminated under certain circumstances, we may be required to pay to Cadence a termination fee of $37.5 million, and under certain circumstances, Cadence may be required to pay us an expense reimbursement of $2 million.

Because the market price of Cadence Class A common stock will fluctuate, our shareholders cannot be certain of the market value of the merger consideration they will receive in the merger.

Upon completion of the merger, each outstanding share of our common stock (except for treasury stock or shares owned by the Company or Cadence (in each case other than in a fiduciary or agency capacity or as a result of debts previously contracted)) will be converted into 1.160 shares of Cadence Class A common stock. The market value of the merger consideration will vary from the closing price of Cadence Class A common stock on the date Cadence and the Company announced the merger, on the date that the joint information statement/proxy statement and prospectus was mailed to our shareholders, on the date of our special meeting, and on the date the merger is completed. Any change in the market price of Cadence Class A common stock prior to the completion of the merger will affect the market value of the merger consideration that our shareholders will receive upon completion of the merger, and there will be no adjustment to the merger consideration for changes in the market price of either shares of Cadence Class A common stock or shares of our common stock, provided that we may terminate the Merger Agreement in certain circumstances relating to a decline in the price of Cadence Class A common stock relative to such price as of the date of the Merger Agreement or to a bank stock index.

The market price of Cadence Class A common stock after the merger may be affected by factors different from those affecting the shares of our common stock currently.

Upon completion of the merger, holders of our common stock will become holders of Cadence Class A common stock. Cadence’s business differs in important respects from that of the Company, and, accordingly, the results of operations of the combined company and the market price of Cadence Class A common stock after the completion of the merger may be affected by factors different from those currently affecting the independent results of operations of each of Cadence and the Company.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Repurchases of Company Common Stock

No shares were repurchased by the Company in the three months ended June 30, 2018. On February 10, 2016, the board of directors authorized the repurchase of up to 1.5 million shares of the Company's outstanding common stock. On February 25, 2016, the Company announced it entered into a written trading plan with a broker for the purpose of purchasing up to 1.5 million shares of the Company's outstanding common stock in accordance with the guidelines specified in Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. On February 9, 2018, the Company extended this existing written trading plan for an additional year. The trading plan expires on the earlier of (a) February 24, 2019, (b) the date on which the maximum aggregate number of shares authorized to be repurchased has been repurchased, or (c) after written notice by the broker or the Company as specified in the trading plan. To date, 270,715 shares have been repurchased and 1,229,285 shares may still be repurchased by the Company under the plan. No shares were repurchased under the plan for the three months ended June 30, 2018.

EX-10.1

RESTRICTED STOCK AGREEMENT

STATE BANK FINANCIAL CORPORATION
2011 OMNIBUS EQUITY COMPENSATION PLAN

GRANTEE: [Ÿ]

NO. OF SHARES: [Ÿ]

GRANT DATE: May 23, 2018

This Restricted Stock Agreement (the “Agreement”) evidences the grant to the Grantee named above (“you”) of the number of restricted shares set forth above (each, an “Award Share,” and collectively, the “Award Shares”) of the $0.01 par value common stock of State Bank Financial Corporation, a Georgia corporation (the “Company”) as of the date of grant set forth above (the “Grant Date”), pursuant to the State Bank Financial Corporation 2011 Omnibus Equity Compensation Plan (the “Plan”) and conditioned upon your agreement to the terms described below. All of the provisions of the Plan are expressly incorporated into this Agreement.

1.Terminology. Capitalized words used in this Agreement and not defined herein shall have the meaning set forth in the Plan.

2.Vesting.

(a)As of the Grant Date, all Award Shares are unvested. All Award Shares shall become vested on the date of the Company’s 2019 annual shareholders’ meeting, unless vested earlier in accordance with this Agreement or as directed by the Committee.

(b)Notwithstanding anything herein or in the Plan to the contrary, all Award Shares shall become vested concurrent with the consummation of a Change of Control as defined in Section 2.1(f) of the Plan, provided that consummation of a Change of Control described in Section 2.1(f)(iii) of the Plan shall occur on the closing date of such Change of Control.

3.Termination of Employment. If your service as a member of the board of directors of the Company (including any Affiliate of the Company) ceases for any reason, all Award Shares that are not then vested will be immediately and automatically forfeited and cancelled upon the date your service as a director terminates. Notwithstanding the preceding sentence, (a) if your service as a director ends on account of your death; or (b) if your service as a director ends on account of your Permanent Disability, you shall vest in the number of Award Shares determined by dividing the total number of Award Shares by 12, and then multiplying that result by the number of months you served as a director between May 23, 2018 and the date your service as a director terminated (with any partial month of service rounded up).

4.Restrictions on Transfer.

(a)Until an Award Share becomes vested, it may not be assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process.

(b)The Company shall not be required to (i) transfer on its books any Award Shares that have been sold or transferred in contravention of this Agreement or (ii) treat as the owner of Award

1

Shares, or otherwise accord voting, dividend or liquidation rights to, any transferee to whom Award Shares have been transferred in contravention of this Agreement.

(c)Upon vesting, an Award Share shall be transferred to you without restrictions on further transfer in accordance with Section 5.

5.Stock Certificates. You will be reflected as the owner of record of the Award Shares as of the Grant Date on the Company’s books. The Company, or its transfer agent, will hold the share certificates for safekeeping, or otherwise retain the Award Shares in uncertificated book entry form, until all the Award Shares become vested or have otherwise been forfeited in accordance with Section 3. Once all of the Award Shares have vested or have otherwise been forfeited in accordance with Section 3, the Company, or its transfer agent, will deliver a stock certificate to you for the outstanding vested Award Shares. Until the Award Shares become vested, any share certificates representing such shares will include a legend to the effect that you may not sell, assign, transfer, pledge, or hypothecate the Award Shares pursuant to this Agreement and the Plan. At the execution of this Agreement, you shall deliver to the Company a stock power, endorsed in blank, with respect to any Award Shares that may be forfeited pursuant to this Agreement.

6.Taxes: Election and Withholding.

(a)  You hereby agree to make adequate provision for foreign, federal, state and local taxes required by law to be withheld, if any, which arise in connection with the grant or vesting of the Award Shares. You may elect to deduct from any compensation or any other payment of any kind (including withholding the issuance of shares of Stock) due you the amount of any federal, state, local or foreign taxes required by law to be withheld as a result of the grant or vesting of the Award Shares in whole or in part up to the highest marginal tax rate required for such taxes; provided, however, that such withholding does not trigger liability accounting under FASB ASC Topic 718. If the Company is required to withhold any amount of tax with respect to such vesting or grant of the Award Shares, the Company shall have the right to require you to pay to the Company the amount of such tax, or, in lieu thereof, to retain or to sell without notice, a sufficient number of shares of the Award Shares to cover the maximum amount of taxes required to be withheld. The Company may report any income to the Internal Revenue Service and any other applicable governmental entity, even if you refuse to make any tax or withholding payments. The value of Award Shares deducted is based on the Fair Market Value of the shares of Stock on the applicable date of vesting.

(b)  You hereby acknowledge that you have been advised by the Company to seek independent tax advice from your own advisors regarding the availability and advisability of making an election under Section 83(b) of the Code, and that any such election, if made, must be made within 30 days of the Grant Date. If you make an election under 83(b) of the Code, you agree to promptly deliver a copy of such election to the Company. You expressly acknowledge that you are solely responsible for filing any such Section 83(b) election with the appropriate governmental authorities, irrespective of the fact that such election is also delivered to the Company. You may not rely on the Company or any of its officers, directors or employees for tax or legal advice regarding this award.

7.Adjustments for Corporate Transactions and Other Events.

(a)    Stock Dividend, Stock Split, Reverse Stock Split and Other Changes.Upon a stock dividend of, or stock split or reverse stock split affecting, the Stock, the number of unvested Award Shares shall, without further action of the Committee or Administrative Agent, be adjusted to reflect such event. The Award Shares shall be adjusted for other changes in the number or kind of outstanding Stock by the

2

Committee in accordance with Sections 4 and/or 12 of the Plan. The Administrative Agent may make adjustments, in its discretion, to address the treatment of fractional shares with respect to the Award Shares as a result of the stock dividend, stock split or reverse stock split. Adjustments under this Section 7 will be made by the Committee, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional Award Shares will result from any such adjustments.

(b)Binding Nature of Agreement. The terms and conditions of this Agreement shall apply with equal force to any additional and/or substitute securities received by you in exchange for, or by virtue of your ownership of, the Award Shares, whether as a result of any spin-off, stock split-up, stock dividend, stock distribution, other reclassification of the Stock of the Company, or similar event, except as otherwise determined by the Committee. If the Award Shares are converted into or exchanged for, or shareholders of the Company receive by reason of any distribution in total or partial liquidation or pursuant to any merger of the Company or acquisition of its assets, securities of another entity, or other property (including cash), then the rights of the Company under this Agreement shall inure to the benefit of the Company’s successor, and this Agreement shall apply to the securities or other property received upon such conversion, exchange or distribution in the same manner and to the same extent as the Award Shares and such securities or other property shall be considered “Award Shares” for all purposes under this Agreement.

(c)Required Forfeitures and Clawbacks. Each Award Share is conditioned on your forfeiting, waiving, or repaying to the Company any amount or Award Share as may be required in compliance with Section 304 of the Sarbanes-Oxley Act, Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the Company’s clawback compliance policy as in effect from time to time and as directed by the Committee. You agree to execute any documents to effect any required forfeiture, waiver or clawback. You agree to assign any Award Shares to the Company or pay any cash amount in lieu thereof as may be required for such compliance.

(d)Non-Guarantee of Employment or Service Relationship. Nothing in the Plan or this Agreement shall alter your at-will or other employment status or other service relationship with the Company, nor be construed as a contract of employment or service relationship between the Company and you, or as a contractual right of you to continue in the employ of, or in a service relationship with, the Company for any period of time, or as a limitation of the right of the Company to discharge you at any time with or without cause or notice and whether or not such discharge results in the forfeiture of any Award Shares or any other adverse effect on your interests under the Plan.

(e)Rights as Shareholder. Except as otherwise provided in this Agreement with respect to the Award Shares which have not vested, you are entitled to all rights of a shareholder of the Company, including the right to vote the Award Shares (subject to any applicable Voting Agreement or similar arrangement to which you may be a party) and receive dividends and/or other distributions declared on the Award Shares.

(f)The Company’s Rights. The existence of the Award Shares shall not affect in any way the right or power of the Company or its shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

3

(g)Notices. All notices and other communications made or given pursuant to this Agreement shall be in writing and shall be sufficiently made or given if hand delivered, mailed by certified mail, transmitted by facsimile or email, addressed to you at the address contained in the records of the Company, or addressed to the Administrative Agent, care of the Company for the attention of its Corporate Secretary at its principal executive office.

(h)Entire Agreement. This Agreement, together with the Plan, contains the entire agreement between the parties with respect to the Award Shares granted hereunder. Any oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement with respect to the Award Shares granted hereunder shall be void and ineffective for all purposes.

(i)Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

(j)Amendment. This Agreement may be amended from time to time by the Committee in its discretion; provided, however, that this Agreement may not be modified in a manner that would have an adverse effect on the Award Shares as determined in the discretion of the Committee, except as provided in the Plan or in a written document signed by each of the parties hereto.

(k)Conformity with Plan. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan. Inconsistencies between this Agreement and the Plan shall be resolved in accordance with the terms of this Agreement. A copy of the Plan has been made available to you.

(l)Governing Law. The validity, construction and effect of this Agreement, and of any determinations or decisions made by the Committee or the Administrative Agent relating to this Agreement, and the rights of any and all persons having or claiming to have any interest under this Agreement, shall be determined exclusively in accordance with the laws of the State of Georgia, without regard to its provisions concerning the applicability of laws of other jurisdictions.

(m)Headings. The headings in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

(n)Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

NOTE 1: BASIS OF PRESENTATION

Overview

State Bank Financial Corporation (the "Company" or "we") is a bank holding company whose business is primarily conducted through its wholly-owned banking subsidiary, State Bank and Trust Company (the "Bank" or "State Bank"). We operate a full service banking business and offer a broad range of commercial and retail banking products to our customers throughout seven of Georgia's eight largest metropolitan statistical areas, or MSAs.

The accompanying unaudited consolidated financial statements for the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statement presentation. The interim consolidated financial statements included herein are unaudited, but reflect all adjustments, consisting of normal and recurring items, which, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the interim period presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the period ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements and notes thereto and the report of our independent registered public accounting firm included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Certain amounts have been reclassified to conform to the current period presentation. The reclassifications had no effect on net income or shareholders’ equity as previously reported.

Proposed Merger with Cadence Bancorporation

On May 11, 2018, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Cadence Bancorporation, a Delaware corporation ("Cadence"). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, the Company will merge with and into Cadence, with Cadence continuing as the surviving corporation. Immediately following the completion of the merger, the Bank will merge with and into Cadence’s wholly owned bank subsidiary, Cadence Bank, N.A. (“Cadence Bank”), with Cadence Bank continuing as the surviving bank. Subject to the terms and conditions of the Merger Agreement, if the merger is completed, Company shareholders will receive 1.160 shares of Cadence Class A common stock, par value $0.01 per share, for each share of Company common stock, par value $0.01 per share, they hold immediately prior to the merger, plus cash in lieu of fractional shares.

The transaction is expected to close in the fourth quarter of 2018, subject to Company shareholder and regulatory approvals in addition to satisfaction of certain other closing conditions.

Accounting Changes and Error Corrections [Abstract]

Adoption of New Accounting Standards and Recent Accounting Pronouncements

NOTE 2: ADOPTION OF NEW ACCOUNTING STANDARDS AND RECENT ACCOUNTING PRONOUNCEMENTS

Adoption of New Accounting Standards

ASU 2018-05 — In March 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The purpose of this ASU is to codify the SEC's guidance issued in Staff Accounting Bulletin 118. The amendments in this update were effective upon issuance. The adoption did not have a material impact on our consolidated financial statements.

ASU 2018-04 — In March 2018, FASB issued ASU 2018-04, Investment - Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273. The purpose of this ASU is to codify the SEC's guidance issued in Staff Accounting Bulletin 117. The amendments in this update were effective upon issuance. The adoption did not have a material impact on our consolidated financial statements.

ASU 2017-12 — On August 28, 2017, FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.The purpose of this ASU is to better align a company’s risk management activities and financial reporting for hedging relationships with the economic objectives of those activities, simplify the hedge accounting requirements, and improve the disclosures of hedging arrangements. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted the amendments in this ASU effective January 1, 2018. The adoption changed the location of changes in fair value of the hedging instrument and hedged item to interest income for periods subsequent to adoption and enhanced disclosures of derivatives and hedging activities. The Company did not elect to modify the measurement methodology for any fair value hedges existing as of the adoption date and there was no cumulative effect adjustment required upon adoption. See Note 8 for enhanced disclosures.

ASU 2018-03 — In February 2018, FASB issued ASU 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10). This Update clarifies certain aspects of the guidance issued in ASU 2016-01 including (i) that an entity measuring an equity security using the measurement alternative may make an irrevocable election to change its measurement approach to a fair value method under Topic 820 for that security and any identical or similar investments of the same issuer, (ii) that fair value adjustments under the measurement alternative should be as of the date the observable transaction for a similar security occurred, (iii) requiring the remeasurement of the entire value of forward contracts and purchased options when observable transactions occur on the underlying equity securities, (iv) that financial liabilities for which the fair value option is elected should follow the guidance in paragraph 825-10-45-5, (v) that changes in the fair value of financial liabilities for which the fair value option is elected relating to the instrument-specific credit risk should first be measured in the currency of denomination and then both components of the change in fair value should be remeasured into the reporting entity's functional currency using end-of-period spot rates, and (vi) that the prospective transition approach should only be applied for instances in which the measurement alternative is applied. The guidance was effective for interim periods beginning after June 15, 2018 and may be early adopted provided ASU 2016-01 was adopted. The Company adopted the amendments in this ASU effective January 1, 2018. The adoption did not have a material impact on our consolidated financial statements.

ASU 2016-01 — In January 2016, FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. The accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted the amendments in this ASU effective January 1, 2018. The adoption of 2016-01 resulted in a reclassification of unrealized loss of $23,000 from accumulated other comprehensive loss to retained earnings.

The new guidance, which does not apply to financial instruments, provides that revenue should be recognized for the transfer of goods or services to customers in an amount equal to the consideration the entity receives or expects to receive in exchange for those goods or services. The guidance also includes expanded disclosure requirements that provide comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company adopted the amendments in this ASU effective January 1, 2018 using the modified retrospective method. Since there was no change to net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not necessary. See below for additional information related to revenue generated from contracts with customers.

Revenue Recognition

On January 1, 2018 the Company adopted ASC Topic 606, using the modified retrospective method. Disclosures of revenue from contracts with customers for periods beginning after January 1, 2018 are presented under ASC Topic 606 and have not materially changed from the prior year amounts. Consistent with this guidance, noninterest income within the scope of this guidance is recognized as services are transferred to our customers in an amount that reflects the considerations we expect to be entitled to in exchange for those services. The Company's revenue streams that were in scope include service charges on deposits, payroll and insurance income, ATM income and other noninterest income.

Services Charges on Deposits - Service charges on deposits primarily consist of monthly maintenance charges, correspondent bank service charges, analysis charges and NSF charges. The fee for NSF charges and certain service charges are fixed and the performance obligation is typically satisfied at the time of the related transaction. The consideration for analysis charges and monthly maintenance charges are variable as the fee can be reduced if the customer meets certain qualifying metrics. The Company's performance obligations are satisfied either at the time of the transaction or over the course of a month.

Payroll and insurance income - Payroll and insurance income consists principally of payroll processing fees, property and casualty brokerage and employee benefits brokerage. Payroll processing fees are charged as the services are provided and the Company satisfied its performance obligation simultaneously. Property and casualty includes the brokerage of both personal and commercial coverages. The placement of the policy is completion of the Company's performance obligation and revenue is recognized at that time. The Company's commission is a percentage of the premium. Employee benefits brokerage consists of assisting companies in designing and managing comprehensive employee benefit programs. The services provided by the Company are collectively benefit management services which are considered a bundle of services that are highly interrelated. Each of the underlying services are activities to fulfill the benefit management service and are not distinct and separate performance obligations. Revenue is recognized over the contract term as services are rendered on a monthly basis. Customer payments are usually received on a monthly basis.

ATM Income - ATM income represents revenues earned from interchange fees and merchant processing fees. Interchange revenues are earned on debit card transactions conducted with payment networks. ATM fees primarily consist of surcharges assessed to our customers for using a non-Bank ATM or a non-Bank customer using our ATM. Such fees generally are recognized concurrently with the delivery of services on a daily basis.

Other - Other noninterest income primarily consists of certain transaction based fees where the performance obligation is satisfied simultaneously with the revenue recognition.

Contract Costs - Costs associated with revenue from contracts with customers related primarily to contracts that have a period of one year or less. The Company has elected to expense the associated costs as incurred.

Contract Balances - The Company records contract assets when revenue is recognized prior to receipt of consideration from the customer. The Company does not have material contract assets at period-end. The Company records contract liabilities when the consideration is received or due in advance of providing services to customers. The Company typically receives payments for its services during the period or at the time services are provided and does not have material contract liabilities at period-end.

Recent Accounting Pronouncements

ASU 2017-09 — On May 10, 2017, FASB issued ASU 2017-09, Scope of Modification Accounting. This Update amends the scope of modification accounting for share-based payment arrangements. It provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718, Compensation—Stock Compensation. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions and classification of the awards are the same immediately before and after the modification. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2017-08 — In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The premium on individual callable debt securities shall be amortized to the earliest call date. This guidance does not apply to securities for which prepayments are estimated on a large number of similar loans where prepayments are probable and reasonably estimable. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. This update should be adopted on a modified retrospective basis with a cumulative-effect adjustment to retained earnings on the date of adoption. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2017-04 — In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The Company should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value. The impairment charge is limited to the amount of goodwill allocated to that reporting unit. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2017-01 — In January 2017, FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The ASU clarifies the definition of a business to assist with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The guidance is not expected to have a significant impact on the Company's financial position, results of operations or disclosures.

ASU 2016-13 — In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU changed the credit loss model on financial instruments measured at amortized cost, available for sale securities and certain purchased financial instruments. Credit losses on financial instruments measured at amortized cost will be determined using a current expected credit loss model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. Purchased financial assets with more-than-insignificant credit deterioration since origination ("PCD assets") measured at amortized cost will have an allowance for credit losses established at acquisition as part of the purchase price. Subsequent increases or decreases to the allowance for credit losses on PCD assets will be recognized in the income statement. Interest income should be recognized on PCD assets based on the effective interest rate, determined excluding the discount attributed to credit losses at acquisition. Credit losses relating to available-for-sale debt securities will be recognized through an allowance for credit losses. The amount of the credit loss is limited to the amount by which fair value is below amortized cost of the available-for-sale debt security. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted and if early adopted, all provisions must be adopted in the same period. The amendments should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the period adopted. A prospective approach is required for securities with other-than-temporary impairment recognized prior to adoption. The Company is still reviewing the impact of the adoption of this guidance and has established a cross-functional implementation team. The Company expects the allowance for credit losses to increase upon adoption with a corresponding adjustment to retained earnings. The ultimate amount of the increase will depend on the portfolio composition, credit quality, economic conditions and reasonable and supportable forecasts at that time.

ASU 2016-02 — In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires the recognition of assets and liabilities arising from the lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend on the classification of the lease as either a finance or an operating lease. Initial costs directly attributable to negotiating and arranging the lease will be included in the asset. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. Lessees will also be required to provide additional qualitative and quantitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements and provide additional information about the nature of an organization’s leasing activities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company expects to elect the package of practical expedients that allows it to not reassess whether any expired or existing contracts represent leases, the lease classification of any expired or existing lease and initial direct costs for any existing or expired leases. The Company expects this standard will have a material impact on its financial statements through gross-up of the balance sheet for lease assets and liabilities. However, no material change to lease expense recognition is expected.

Acquisitions

NOTE 3: ACQUISITIONS

Acquisition of AloStar Bank of Commerce

On September 30, 2017, State Bank completed its acquisition of AloStar Bank of Commerce ("AloStar"). State Bank Interim Corp., a wholly-owned subsidiary of State Bank, merged with and into AloStar, immediately followed by the merger of AloStar with and into State Bank. Under the terms of the merger agreement, each share of AloStar common stock was converted into the right to receive $24.26 in cash. Total consideration paid was approximately $195.0 million and the final merger consideration was distributed in October 2017.

The merger of AloStar was accounted for under the acquisition method of accounting. Assets acquired, liabilities assumed and consideration exchanged were recorded at their respective acquisition date fair values. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available. Goodwill of $7.1 million was generated from the acquisition, all of which is expected to be deductible for income tax purposes.

The following table summarizes the assets acquired and liabilities assumed and the consideration payable by the Company at the acquisition date (dollars in thousands):

At June 30, 2018, the Company held 155 debt securities that were in an unrealized loss position. Market changes in interest rates and credit spreads may result in temporary unrealized losses as market prices of securities fluctuate. The Company reviews its investment portfolio on a quarterly basis for indications of other than temporary impairment ("OTTI"). The severity and duration of impairment and the likelihood of potential recovery of impairment is considered along with the intent and ability to hold any impaired security to maturity or recovery of carrying value. More specifically, when analyzing the nonagency portfolio, the Company uses cash flow models that estimate cash flows on security-specific collateral and the transaction structure. Future expected credit losses are determined by using various assumptions, the most significant of which include current default rates, prepayment rates and loss severities. Credit information is available and modeled at the loan level underlying each security during the OTTI analysis; the Company also considers information such as loan to collateral values, FICO scores and geographic considerations, such as home price appreciation or depreciation. These inputs are updated quarterly or as changes occur to ensure that the most current credit and other assumptions are utilized in the analysis. If, based on the analysis, the Company does not expect to recover the entire amortized cost basis of the security, the expected cash flows are discounted at the security's initial effective interest rate to arrive at a present value amount. OTTI credit losses reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of these securities. At June 30, 2018, there was no intent to sell any of the securities in an unrealized loss position, and it is more likely than not the Company will not be required to sell these securities. Furthermore, the present value of cash flows expected to be collected exceeded the Company's amortized cost basis of the debt securities; therefore, these securities are not deemed to be other than temporarily impaired.

During the second quarter of 2018, the Company transferred a $10.1 million corporate security from held-to-maturity to available-for-sale. The issuing corporation is the target of a merger which caused the Company to change its assessment of the issuing corporation's creditworthiness. Subsequently, the Company sold a $4.0 million portion of this debt security's par value.

Sales and calls of securities are summarized in the following table for the periods presented (dollars in thousands):

	Three Months Ended					Six Months Ended
	June 30					June 30
Debt Securities Available-For-Sale	2018		2017			2018		2017
Proceeds from sales and calls	$	4,275	$	21,942		$	4,275	$	64,778

Gross losses on sales and calls	—		(76		)	—		(93		)
Net realized gains on sales and calls	$	250	$	13		$	250	$	25

The composition of debt 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. Debt securities with an aggregate fair value of $103.9 million and $116.1 million at June 30, 2018 and December 31, 2017, respectively, were pledged to secure public deposits and repurchase agreements.

Balance, end of period	$	144,474		$	130,837		$	144,474		$	130,837

Purchased credit impaired loans are initially recorded at fair value at the acquisition date. The Company re-estimates expected cash flows on purchased credit impaired loans on a quarterly basis. 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 first 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 on purchased credit impaired loans are presented in the following table for the periods presented (dollars in thousands):

	Three Months Ended						Six Months Ended
	June 30						June 30
Changes in Accretable Discount	2018			2017			2018			2017
Balance, beginning of period	$	57,854		$	63,066		$	57,927		$	69,301

Transfers to accretable discounts and exit events, net	2,279			5,970			8,152			7,412
Balance, end of period	$	53,538		$	59,808		$	53,538		$	59,808

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 purchased credit impaired loans.

At June 30, 2018 and December 31, 2017, loans with a carrying value of $3.1 billion were pledged for lines of credit. At June 30, 2018, consumer mortgage loans secured by residential real estate properties totaling $104,000 were in formal foreclosure proceedings.

For each period indicated, a portion of the Company's purchased credit impaired loans were past due, including many that were 90 days or more past due; however, such delinquencies were included in the Company's performance expectations in determining the fair values of purchased credit impaired loans at each acquisition and at subsequent valuation dates. All purchased credit impaired loan cash flows and the timing of such cash flows continue to be estimable and probable of collection and thus accretion income continues to be recognized on these assets. As such, the referenced purchased credit impaired loans are not considered nonperforming assets.

Asset Quality Grades:

The Company assigns loans into risk categories based on relevant information about the ability of borrowers to pay their debts, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. A loan's risk grade is assigned at inception based upon the strength of the repayment sources and reassessed periodically throughout the year. Loans over certain dollar thresholds identified as having weaknesses are subject to more frequent review. In addition, the Company's internal loan review department provides an ongoing, comprehensive and independent assessment of credit risk within the Company.

Loans are graded on a scale of 1 to 9. 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.

Loss (Grade 9)—Loans classified as loss are considered uncollectible and have little value to the Company and their continuance as an active relationship is not warranted.

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

The following table presents the risk grades of the purchased credit impaired loan portfolio, by class of loans (dollars in thousands):

Troubled Debt Restructurings (TDRs)

Total troubled debt restructurings (TDRs) were $6.9 million at June 30, 2018, with $28,000 in related allowance. At December 31, 2017, TDRs totaled $1.5 million with no related allowance. At June 30, 2018, there was one commitment to extend credit to a borrower with an existing troubled debt restructuring totaling $599,000. At December 31, 2017, there were no commitments to extend credit to borrowers with an existing troubled debt restructuring. Purchased credit impaired loans modified post-acquisition are not removed from their accounting pools and accounted for as TDRs, even if those loans would otherwise be deemed TDRs.

The following table provides information on loans that were modified as TDRs during the periods presented (dollars in thousands):

	June 30, 2018					June 30, 2017

(1) The pre-modification and post-modification recorded investment amount represents the recorded investment on the date of the loan modification. Since the modifications on these loans were either an interest rate concession or payment term extension, not principal reductions, the pre-modification and post-modification recorded investment amount is the same.

There were no loans modified as a TDR during the three months endedJune 30, 2018 or 2017. During the six months endedJune 30, 2018, there was one loan modified as a TDR which subsequently defaulted within twelve months of its modification date with a recorded investment of $848,000. During the six months ended June 30, 2017, there were no TDRs that subsequently defaulted within twelve months of their modification dates.

Transfers and Servicing [Abstract]

SBA Servicing Rights

NOTE 7: SBA SERVICING RIGHTS

All sales of SBA loans, consisting of the guaranteed portion, are executed on a servicing retained basis. These loans, which are partially guaranteed by the SBA, are generally secured by business property such as real estate, inventory, equipment and accounts receivable. During the three and six months ended June 30, 2018, the Company sold SBA loans with unpaid principal balances totaling $9.8 million and $18.4 million, respectively, and recognized $1.0 million and $1.9 million in gains on the loan sales, respectively. During the three and six months ended June 30, 2017, the Company sold SBA loans with unpaid principal balances totaling $16.5 million and $25.0 million, respectively, and recognized $1.6 million and $2.5 million in gains on the loan sales, respectively. The Company retains the related loan servicing rights and receives servicing fees on the sold loans. Both the servicing fees and the gains on sales of loans are recorded in SBA income on the consolidated statements of income. SBA servicing fees totaled $462,000 and $938,000 for the three and six months ended June 30, 2018, respectively. SBA servicing fees totaled $407,000 and $840,000 for the three and six months ended June 30, 2017, respectively. At June 30, 2018 and December 31, 2017, the Company serviced SBA loans for others with unpaid principal balances totaling $184.8 million and $185.6 million, respectively.

The table below summarizes the activity in the SBA servicing rights asset for the periods presented (dollars in thousands):

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. As indicated, changes in fair value based on adverse changes in model inputs and/or assumptions generally cannot be extrapolated because the relationship of the change in input or assumption to the change in fair value may not be linear. In addition, the effect of an adverse variation in a particular input or assumption on the value of the SBA servicing rights is calculated without changing any other input or assumption. In reality, changes in one factor may magnify or counteract the effect of the change.

The risk inherent in the SBA servicing rights asset includes prepayments at different rates than anticipated or resolution of loans at dates not consistent with the estimated expected lives. These events would cause the value of the servicing asset to decline at a faster or slower rate than originally anticipated.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE INSTRUMENTS & HEDGING ACTIVITIES

NOTE 8: DERIVATIVE 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.

Credit and Collateral Risks for Interest Rate Swaps and Caps

The Company manages credit exposure on interest rate swap and cap transactions by entering into a bilateral credit support agreement with each counterparty. The credit support agreements require collateralization of exposures beyond specified minimum threshold amounts. The details of these agreements, including the minimum thresholds, vary by counterparty. Refer to Note 9, 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 June 30, 2018, the Company had no derivatives in a net liability position under these agreements.

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.

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.

Derivatives Designated as Hedging Instruments

Fair Value Hedges

The Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps, designated as fair value hedges, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments over the life of the agreements without the exchange of the underlying notional amount. The gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. At June 30, 2018 and December 31, 2017, the Company had 72 and 84 interest rate swaps with an aggregate notional amount of $123.0 million and $141.9 million, designated as fair value hedges associated with the Company's fixed rate loan program.

The tables below presents the effect of fair value hedges on the consolidated statements of financial condition for the periods presented (dollars in thousands):

Line Item in the Statement of Financial Condition in Which the Hedged Item Is Included	Carrying Amount of the Hedged Asset				Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Asset

Loans	$	119,559	$	139,391	$	(4,145	)	$	(1,892	)
Total	$	119,559	$	139,391	$	(4,145	)	$	(1,892	)

Cash Flow Hedges

The Company used 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 former cash flow hedges were for the purpose of capping interest rates paid on deposits, which protected 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. These caps expired in the first quarter of 2018. Amounts reported in AOCI related to derivatives were reclassified to interest expense as the interest rate cap premium was amortized over the life of the cap.

Balance Sheet Offsetting and Repurchase Agreements

NOTE 9: BALANCE SHEET OFFSETTING AND REPURCHASE AGREEMENTS

Balance Sheet Offsetting

Certain financial instruments, including repurchase agreements and derivatives (interest rate swaps and caps), may be eligible for offset in the consolidated statements of financial condition and/or subject to master netting arrangements or similar agreements; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes.

The table below presents information about the Company’s financial instruments that are eligible for offset in the consolidated statements of financial condition at the dates presented (dollars in thousands):

(1) The application of collateral cannot reduce the net amount below zero; therefore, excess collateral received/posted is not reflected in this table. All positions are fully collateralized.

Repurchase Agreements

The Company utilizes securities sold under repurchase agreements to facilitate the needs of its customers. Securities sold under repurchase agreements consist of balances in the transaction accounts of commercial customers swept nightly to an overnight investment account and are collateralized with investment securities having a market value no less than the balance borrowed. The investment securities pledged are subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below the balance of the repurchase agreements on a daily basis and may be required to provide additional collateral. Securities pledged as collateral are maintained with a safekeeping agent.

At June 30, 2018 and December 31, 2017, securities sold under repurchase agreements were $13.5 million and $25.2 million, respectively, all of which mature on an overnight and continuous basis. At both June 30, 2018 and December 31, 2017, investment securities pledged for the outstanding repurchase agreements consisted of U.S. government sponsored agency mortgage-backed securities.

Regulatory Matters

NOTE 10: REGULATORY MATTERS

Regulatory Capital Requirements

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.

Beginning on January 1, 2016, the Company and State Bank must maintain a capital conservation buffer to avoid restrictions on capital distributions or discretionary bonus payments. This buffer must consist solely of Common Equity Tier 1 Capital, but the buffer applies to all three measurements (Common Equity Tier 1, Tier 1 capital and total capital) in addition to the minimum risk-based capital requirements. The capital conservation buffer required for 2018 is common equity equal to 1.875% of risk-weighted assets and will increase by .625% per year until reaching 2.5% beginning January 1, 2019.

The minimum regulatory capital ratios and ratios to be considered well-capitalized under prompt corrective action provisions at both June 30, 2018 and December 31, 2017 are presented in the table below:

Capital Ratio Requirements	Minimum Requirement	Well-capitalized (1)
Common Equity Tier 1 (CET1) capital ratio	4.50%	6.50%
Tier 1 risk-based capital ratio	6.00%	8.00%
Total risk-based capital ratio	8.00%	10.00%
Tier 1 leverage ratio	4.00%	5.00%

(1) The prompt corrective action provisions are only applicable at the bank level.

At June 30, 2018 and December 31, 2017, the Company and State Bank exceeded all regulatory capital adequacy requirements to which they were subject.

Regulatory Restrictions on Dividends

Regulatory policy statements provide that generally bank holding companies should pay dividends only out of current operating earnings and that the level of dividends must be consistent with current and expected capital requirements. Dividends received from State Bank have been the primary source of funds available for the declaration and payment of dividends to the Company's common shareholders.

Federal and state banking laws and regulations restrict the amount of dividends banks may distribute without prior regulatory approval. At June 30, 2018, State Bank had no capacity to pay dividends to the Company without prior regulatory approval.

At June 30, 2018, the Company had $66.5 million in cash and due from bank accounts, which can be used for additional capital as needed by State Bank, payment of holding company expenses, payment of dividends to shareholders, or for other corporate purposes.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

NOTE 11: COMMITMENTS AND CONTINGENT LIABILITIES

Commitments

In order to meet the financing needs of its customers, the Company maintains financial instruments with off-balance-sheet risk in the normal course of business. These financial instruments include commitments to extend credit and standby letters of credit and involve, to varying degrees, elements of credit, interest rate and/or liquidity risk. Such financial instruments are recorded when they are funded and the related fees are generally recognized when collected.

Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed maturity dates or other termination clauses with required fee payments. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The amount of collateral required, if deemed necessary upon extension of credit, is determined on a case by case basis by management through credit evaluation of the customer.

Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those guarantees are issued primarily to support public and private borrowing arrangements. In order to minimize its exposure, the Company's credit policies govern the issuance of standby letters of credit.

The Company's exposure to credit loss is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments.

A summary of the Company's commitments is as follows (dollars in thousands):

	June 30, 2018		December 31, 2017
Commitments to extend credit:
Fixed	$	91,509	$	65,117
Variable	944,668		914,524
Letters of credit:
Fixed	5,759		5,978
Variable	6,895		11,428
Total commitments	$	1,048,831	$	997,047

The fixed rate loan commitments have maturities ranging from one month to thirteen years. Management takes appropriate actions to mitigate interest rate risk associated with these fixed rate commitments through various measures including, but not limited to, the use of derivative financial instruments.

Contingent Liabilities

Mortgage loan sales agreements contain covenants that may, in limited circumstances, require the Company to repurchase or indemnify the investors for losses or costs related to the loans the Company has sold. As a result of the potential recourse provisions, the Company maintains a recourse liability for mortgage loans sold to investors. At June 30, 2018, the recourse liability was $296,000.

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 12: FAIR VALUE

Overview

Fair value measurements are determined based on the assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, the Financial Accounting Standards Board's Accounting Standards Codification Topic 820 ("ASC 820") Fair Value Measurements and Disclosures establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs classified within Level 3 of the hierarchy).

Fair Value Hierarchy

Level 1

Valuation is based on inputs that are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2

Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as interest rates, yield curves observable at commonly quoted intervals, and other market-corroborated inputs.

Level 3

Valuation is generated from techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The Company evaluates fair value measurement inputs on an ongoing basis in order to determine if there is a change of sufficient significance to warrant a transfer between levels. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company's valuation process. For the six months endedJune 30, 2018 and the year ended December 31, 2017, there were no transfers between levels.

Fair Value Option

ASC 820 allows companies to report selected financial assets and liabilities at fair value using the fair value option. The changes in fair value are recognized in earnings and the assets and liabilities measured under this methodology are required to be displayed separately on the balance sheet. The Company made the election to record mortgage loans held-for-sale at fair value under the fair value option, which allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to hedge them without the burden of complying with the requirements for hedge accounting.

Financial Assets and Financial Liabilities Measured on a Recurring Basis

The Company uses the following methods and assumptions in estimating the fair value of its financial assets and financial liabilities on a recurring basis:

Investment Securities Available-for-Sale

At June 30, 2018, 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.

Hedged Loans

Loans involved in fair value hedges are recorded at fair value on a recurring basis. The estimated fair value is determined using Level 2 inputs consistent with the valuation methodology for interest rate swaps discussed below. The Company does not record other loans held for investment at fair value on a recurring basis.

Mortgage Loans Held-for-Sale

Mortgage loans held-for-sale are recorded at fair value on a recurring basis. The estimated fair value is determined using Level 2 inputs based on observable data such as the existing forward commitment terms or the current market value of similar loans. Interest income is recorded in interest income on the consolidated statements of income and is based on the contractual terms of the loan. None of these loans were 90 days or more past due or on nonaccrual at June 30, 2018.

At June 30, 2018, the aggregate fair value of the Company's mortgage loans held-for-sale was $39.2 million and the contractual balance including accrued interest was $38.1 million, with a fair value mark totaling $1.2 million. The Company recognized a gain of $251,000 and a gain of $617,000 for the three and six months ended June 30, 2018, respectively, related to the change in fair value of the mortgage loans held-for-sale, included in "mortgage banking income" on the consolidated statements of income. For the three and six months ended June 30, 2017, the amount recognized related to the change in fair value of the mortgage loans held-for-sale was a loss of $243,000 and a gain of $482,000, respectively.

Derivative Financial Instruments

Interest Rate Swaps and Caps

The Company uses interest rate swaps to provide longer-term fixed rate funding to its customers and interest rate caps to mitigate the interest rate risk on its variable rate liabilities. The majority of these derivatives are traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract. Therefore, these derivative contracts are classified as Level 2. The Company utilizes an independent third party valuation company to validate the dealer prices. In cases where significant credit valuation adjustments are incorporated into the estimation of fair value, reported amounts are considered to have been derived utilizing Level 3 inputs.

The Company evaluates the credit risk of its counterparties as well as that of the Company. The Company has considered factors such as the likelihood of default by the Company and its counterparties, its net exposures, and remaining contractual life, among other things, in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting arrangements, as well as considering the amount of collateral securing the position. The Company reviews its counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken to adjust the exposure. The Company also utilizes this approach to estimate its own credit risk on derivative liability positions. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position.

Mortgage Derivatives

Mortgage derivatives include interest rate lock commitments to originate residential mortgage loans held-for-sale. The Company relies on an internal valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held-for-sale. The model groups the interest rate lock commitments by interest rate and term, applies an estimated pull-through rate based on historical experience, and then multiplies by quoted investor prices which were determined to be reasonably applicable to the loan commitment group based on interest rate, term, and rate lock expiration date of the loan commitment group. While there are Level 2 and 3 inputs used in the valuation model, the Company has determined that the majority of the inputs significant in the valuation of the interest rate lock commitments fall within Level 3 of the fair value hierarchy. Changes in the fair values of these derivatives are included in "mortgage banking income" on the consolidated statements of income.

Mortgage derivatives also include forward commitments to sell residential mortgage loans to various investors when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitment to fund loans. The Company also relies on an internal valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e., an estimate of what the Company would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available (Level 2). Changes in the fair values of these derivatives are included in "mortgage banking income" on the consolidated statements of income.

SBA Servicing Rights

The Company has the rights to service a portfolio of SBA loans. The SBA servicing rights are measured at fair value when loans are sold on a servicing retained basis. The servicing rights are subsequently measured at fair value on a recurring basis utilizing Level 3 inputs. Management uses a model operated and maintained by a third party to calculate the present value of future cash flows using the third party's market-based assumptions. The future cash flows for each asset are based on the asset's unique characteristics and the third party's market-based assumptions for prepayment speeds, default and voluntary prepayments. For non-guaranteed portions of servicing assets, future cash flows are estimated using loan specific assumptions for losses and recoveries. Adjustments to fair value are recorded as a component of "SBA income" on the consolidated statements of income. Please reference Note 7 for the roll-forward of the SBA servicing rights asset at fair value utilizing level 3 inputs.

Financial Assets Measured on a Nonrecurring Basis

The Company uses the following methods and assumptions in estimating the fair value of its financial assets on a nonrecurring basis:

Impaired Loans

Loans, excluding purchased credit impaired loans, are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The fair values of impaired loans are measured on a nonrecurring basis and are based on the underlying collateral value of each loan if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs that are based on observable market data such as an appraisal. Updated appraisals are obtained on at least an annual basis. Level 3 inputs are based on the Company's customized discounting criteria when management determines the fair value of the collateral is further impaired.

The following table presents financial assets measured at fair value on a nonrecurring basis at the dates indicated, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

	Quoted Market Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
June 30, 2018
Impaired loans	$	—	$	—	$	68,969	$	68,969

Impaired loans	$	—	$	—	$	11,804	$	11,804
Total nonrecurring assets at fair value	$	—	$	—	$	11,804	$	11,804

Impaired loans, excluding purchased credit impaired loans, that are measured for impairment using the fair value of collateral for collateral dependent loans had recorded investments of $70.9 million and $13.0 million with respective valuation allowances of $1.9 million and $1.2 million at June 30, 2018 and December 31, 2017, 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):

Earnings Per Share

NOTE 13: 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. There were no anti-dilutive securities excluded from the computation of earnings per share in the periods presented.

Earnings per share have been computed based on the following weighted average number of common shares outstanding (dollars in thousands, except per share data):

Equity [Abstract]

Accumulated Other Comprehensive Income

NOTE 14: ACCUMULATED OTHER COMPREHENSIVE INCOME

Accumulated other comprehensive income, or AOCI, is reported as a component of shareholders' equity. AOCI can include, among other items, unrealized holding gains and losses on investment securities available-for-sale, unrealized gains and losses on investment securities available-for-sale transferred to held-to-maturity, and gains and losses on derivative instruments that are designated as, and qualify as, cash flow hedges. Unrealized holding gains and losses on securities transferred to held-to-maturity are amortized over the estimated remaining life of the security as an adjustment to yield, offsetting the related amortization/accretion of the net premium/discount created in the transfer. The components of AOCI are reported net of related tax effects.

The components of AOCI and changes in those components for the periods presented are as follows (dollars in thousands):
