NOTES TO 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 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. 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 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 2018-16 — In October 2018, FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. This ASU permits the use of the OIS rate based on SOFR as a benchmark interest rate for hedge accounting purposes. 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. The guidance is not expected to have a significant impact on the Company’s financial position, results of operations or disclosures.

ASU 2018-13 — In August 2018, FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This Update is part of the FASB’s ongoing disclosure framework project and modifies disclosure requirements of fair value measurements. The guidance removed the requirement to disclose (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) the policy for timing of transfers between levels and (iii) the valuation processes for Level 3 fair value measurements. The guidance also added required disclosures of the change in unrealized gains and losses for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2019. 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, Leases (Topic 842), ASU 2018-10 Codification Improvements to Topic 842, Leases and ASU 2018-11 Leases (Topic 842): Targeted Improvements — 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The following table presents certain pro forma information as if AloStar had been acquired on January 1, 2017 (dollars in thousands, except per share amounts) . These results combine the historical results of AloStar in the Company’s consolidated statements of income and, while certain adjustments were made for the estimated impact of certain fair value adjustments and other acquisition-related activity, they are not indicative of what would have occurred had the acquisition taken place on January 1, 2017. Merger-related costs are not included in the pro forma statements below.

The following is a summary of the purchased credit impaired loans acquired in the AloStar transaction on September 30, 2017 (dollars in thousands) :

On September 30, 2017, the fair value of the purchased non-credit impaired loans acquired in the AloStar transaction was $641.0 million. The gross contractual amounts receivable of the purchased non-credit impaired loans at acquisition was $707.0 million, of which $9.3 million was the amount of contractual cash flows not expected to be collected.

The amortized cost and estimated fair value of debt securities by contractual maturities are summarized in the tables below (dollars in thousands) :

14

At September 30, 2018, the Company held 152 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 September 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 was 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.
