Notes to consolidated financial statements

(Unaudited)

(Amounts are in thousands except share and per share amounts)

Note (1)—Basis of presentation:

FB Financial Corporation (the “Company”) is a bank holding company, headquartered in Nashville, Tennessee. The Company operates through its wholly owned bank subsidiary, FirstBank (the “Bank”), with 56 full-service bank branches across Tennessee, North Alabama and North Georgia, and a national mortgage business with office locations across the Southeast.

The consolidated financial statements, including the notes thereto of the Company, have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) interim reporting requirements, and therefore do not include all information and notes included in the annual consolidated financial statements in conformity with GAAP. These interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K.

The unaudited consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. The results for interim periods are not necessarily indicative of results for a full year.

The accompanying consolidated financial statements have been prepared in conformity with GAAP and general banking industry. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported results of operations for the periods then ended. Actual results could differ significantly from those estimates.

Certain prior period amounts have been reclassified to conform to the current period presentation without any impact on the reported amounts of net income or shareholders’ equity.

Effective July 31, 2017, the Bank completed its previously announced acquisitions of Clayton Bank and Trust and American City Bank headquartered in Knoxville, Tennessee and Tullahoma, Tennessee, respectively.  See Note 2, “Mergers and acquisitions” in these Notes to the consolidated unaudited financial statements for further details regarding acquisitions.

Prior to May 31, 2018, the Company was considered a “controlled company” and was controlled by the Company’s Executive Chairman and former majority shareholder, James W. Ayers. During the second quarter of 2018, the Company completed a secondary offering of 3,680,000 shares of common stock pursuant to the Company’s effective registration statement on Form S-3 whereby James W. Ayers was the seller. As a result of this transaction, the Company ceased to qualify as a “controlled company” as the selling shareholder’s ownership was reduced to approximately 44% of the voting power of the Company’s issued and outstanding shares of common stock. The Company continues to qualify as an emerging growth company as defined by the “Jumpstart Our Business Startups Art” (“JOBS Act”).

Subsequent events

The Company has evaluated, for consideration of recognition or disclosure, subsequent events that occurred through the date of issuance of these financial statements. The Company has determined that there were no other subsequent events other than described below that occurred after June 30, 2018, but prior to the issuance of these financial statements that would have a material impact on the Company’s consolidated financial statements.

On July 19, 2018, the Company declared a regular quarterly dividend of $0.06 per share to be paid on August 15, 2018 to shareholders of record as of July 31, 2018, totaling approximately $1,909.

On August 7, 2018, the Federal Home Loan Bank of Cincinnati increased the capacity on the Company’s line of credit from $300,000 to $800,000.

Earnings per share

Basic earnings per common share (“EPS”) excludes dilution and is computed by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the dilutive effect of additional potential common shares issuable under the restricted stock units granted but not yet vested and distributable. Diluted EPS is computed by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding for the year, plus an incremental number of common-equivalent shares computed using the treasury stock method.

(Amounts are in thousands except share and per share amounts)

Unvested share-based payment awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered to participate with common shareholders in undistributed earnings for purposes of computing EPS. Companies that have such participating securities, including FB Financial, are required to calculate basic and diluted EPS using the two-class method. Certain restricted stock awards granted by the Company include non-forfeitable dividend equivalents and are considered participating securities. Calculations of EPS under the two-class method (i) exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities and (ii) exclude from the denominator the dilutive impact of the participating securities.

The following is a summary of the basic and diluted earnings per common share calculation for each of the periods presented:

Government National Mortgage Association (“GNMA”) optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing and was the original transferor.  At the servicer’s option and without GNMA’s prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan.  Under FASB ASC Topic 860, “Transfers and Servicing,” this buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional.  When the Company is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as loans held for sale, regardless of whether the Company intends to exercise the buy-back option if the buyback option provides the transferor a more-than-trivial benefit. At June 30, 2018, there were $52,212 of delinquent GNMA loans that had previously been sold; however, the Company determined there was not a “more-than-trivial benefit” based on an analysis of interest rates and an assessment of potential reputational risk associated with these loans. As such, the Company did not rebook the GNMA loans as of June 30, 2018. At December 31, 2017, rebooked GNMA loans held for sale amounted to $43,035 with an offsetting liability included in accrued expenses and other liabilities in the same amount. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option.

Recently adopted accounting principles:

Except as set forth below, the Company did not adopt any new accounting policies that were not disclosed in the Company’s 2017 audited consolidated financial statements included on Form 10-K.

On January 1, 2018, the Company adopted the following newly issued accounting standards:

In May 2014, the FASB issued an update to Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”. The Company adopted this guidance on January 1, 2018 and all subsequent amendments to the ASU (collectively, “ASC 606”) which (i) creates a single framework for recognizing revenue from contracts with

8

(Amounts are in thousands except share and per share amounts)

customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets, such as OREO. The majority of the Company’s revenues come from interest income and other sources, including loans, leases, securities and derivatives that are outside the scope of ASC 606.  The Company’s services that fall within the scope of ASC 606 are presented within Noninterest income and are recognized as revenue as the Company satisfies its obligation to the customer.  Services within the scope of ASC 606 include deposit service charges on deposits, interchange income, investment services and trust income, and the sale of OREO, all within the Banking Segment.  The Company has evaluated the effect of this updated on these fee-based income streams and concluded that adoption did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded.

The following is a summary of the implementation considerations for the revenue streams that fall within the scope of Topic 606:

• Service charges on deposits, investment services and trust income, and interchange fees — Fees from these services are either transaction based, for which the performance obligations are satisfied when the individual transaction is processed, or set periodic service charges, for which the performance obligations are satisfied over the period the service is provided. Transaction based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on the Company's revenue recognition practice for these services.

• Gains on sales of other real estate — ASU 2014-09 creates Topic 610-20, under which a gain on sale should be recognized when a contract for sale exists and control of the asset has been transferred to the buyer. Topic 606 list several criteria which must exist to conclude that a contract for sale exists, including a determination that the institution will collect substantially all of the consideration to which it is entitled. This presents a key difference between the current and new guidance related to the recognition of the gain when the institution finances the sale of the property. Rather than basing recognition on the amount of the buyer's initial investment, which was the primary consideration under prior guidance, the analysis is now based on various factors including not only the loan to value, but also the credit quality of the borrower, the structure of the loan, and any other factors that may affect collectability. While these differences may affect the decision to recognize or defer gains on sales of other real estate in circumstances where the Company has financed the sale, these amounts have not been material to its financial statements.

In January 2016, the FASB released ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.” The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and adjust the fair value disclosures for financial instruments carried at amortized cost such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value such that these securities can be carried at cost less any impairment. Results for reporting periods beginning after January 1, 2018 are presented under this method while prior period disclosures are presented under legacy GAAP. On January 1, 2018, the Company recorded a net loss in beginning retained earnings of $109 in connection with this transition.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230).” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. This adoption did not have an impact on our financial statements.

In May 2017, the FASB issued ASU 2017-09, “Stock Compensation - Scope of Modification Accounting (Topic 718): Scope of Modification Accounting.” The amendments in this ASU provide guidance on when changes to the terms or conditions of a share-based payment award are to be accounted for as modifications. Under ASU 2017-09, entities are not required to apply modification accounting to a share-based payment award when the award’s fair value, vesting conditions, and classification as an entity or a liability instrument remain the same after the change. ASU 2017-09 is effective for all entities beginning after December 15, 2017 including interim periods within the fiscal year. The adoption of this update on January 1, 2018 did not have a significant impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU make more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess

(Amounts are in thousands except share and per share amounts)

effectiveness. There was no impact to the Company’s financial statements or disclosures as a result of this early adoption as of January 1, 2018.

Newly issued not yet effective accounting standards:

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The update will require lessees to recognize right-of-use assets and lease liabilities for all leases not considered short term leases. The provisions of the update also include (a) defining direct costs to only include those incremental costs that would not have been incurred if the lease had not been entered into, (b) circumstances under which the transfer contract in a sale-leaseback transaction should be accounted for as the sale of an asset by the seller-lessee and the purchase of an asset by the buyer-lessor, and (c) additional disclosure requirements. The provisions of this update become effective for interim and annual periods beginning after December 15, 2018. Management is currently evaluating the potential impact of this update.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as, the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will become effective for interim and annual periods beginning after December 15, 2019. Management is currently evaluating the potential impact of this update.

In March 2017, the FASB issued ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. The adoption of this update will not have an impact on the Company’s consolidated financial statements.

Note (2)—Mergers and acquisitions:

Clayton Bank and Trust and American City Bank

On July 31, 2017, the Bank completed its merger with Clayton Bank and Trust (“CBT”) and American City Bank (“ACB” and together with CBT, the “Clayton Banks”), pursuant to the Stock Purchase Agreement with Clayton HC, Inc., a Tennessee corporation (“Seller”), and James L. Clayton, the majority shareholder of Seller, dated February 8, 2017, as amended on May 26, 2017, with a purchase price of approximately $236,484.  The Company issued 1,521,200 shares of common stock and paid cash of $184,200 to purchase all of the outstanding shares of the Clayton Banks.  At closing, the Clayton Banks merged with and into FirstBank, with FirstBank continuing as the surviving banking entity.

Prior to the merger, the Clayton Banks operated 18 banking locations across Tennessee. The merger with the Clayton Banks has allowed the Company to further its strategic initiatives by expanding its geographic footprint in Knoxville and other Tennessee markets and accelerating the growth of the Company’s Banking segment.

Goodwill of $90,323 recorded in connection with the transaction resulted primarily from anticipated synergies arising from the combination of certain operational areas of the Clayton Banks and the Company as well as the purchase premium inherent to buying a complete and successful banking operation. Goodwill is included in the Banking segment as substantially all of the operations resulting from the Clayton Banks merger is included in the Banking segment.

In connection with the transaction, the Company incurred $0 and $1,193 in merger and conversion expenses during the three and six months ended June 30, 2018 compared with $767 and $1,254 for the same periods in 2017.

For income tax purposes, the merger with the Clayton Banks was treated as an asset purchase. As an asset purchase for income tax purposes, the carrying value of assets and liabilities for the Clayton Banks are the same for both financial reporting and income tax purposes; therefore, no deferred taxes were recorded at the date of acquisition. Additionally, this treatment allows for the deductibility of the goodwill and core deposit intangible for income tax purposes over 15 years.

The Company accounted for the Clayton Banks transaction under the acquisition method under ASC Topic 805. Accordingly, the fair value of the assets acquired and liabilities assumed along with the resulting goodwill was recorded as of the date of the merger. The Company’s operating results for the three and six months ended June 30, 2018 include the operating results of the acquired assets and assumed liabilities of the Clayton Banks.

As of December 31, 2017, the Company finalized its valuation of all assets acquired and liabilities assumed, resulting in no material changes to preliminary purchase accounting adjustments. The following tables present the final estimated fair value of net assets acquired as of the July 31, 2017 acquisition date and the consideration paid and an allocation of the purchase price to net assets acquired:

As of June 30, 2018 and December 31, 2017, the Company’s securities portfolio consisted of 329 and 294 securities, 181 and 124 of which were in an unrealized loss position, respectively.

The Company evaluates securities with unrealized losses for other-than-temporary impairment (OTTI) on a quarterly basis and recorded no OTTI for the three or six months ended June 30, 2018 and 2017. Impairment is assessed at the

13

(Amounts are in thousands except share and per share amounts)

individual security level. The Company considers an investment security impaired if the fair value of the security is less than its cost or amortized cost basis. For debt securities, the unrealized losses associated with these investment securities are primarily driven by interest rates and are not due to the credit quality of the securities. The Company currently does not intend to sell those investments with unrealized losses, and it is unlikely that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity.

Note (4)—Loans and allowance for loan losses:

Loans outstanding at June 30, 2018 and December 31, 2017, by major lending classification are as follows:

As of June 30, 2018 and December 31, 2017, $598,522 and $761,197, respectively, of qualifying residential mortgage loans (including loans held for sale) and $539,621 and $207,370, respectively, of qualifying commercial mortgage loans were pledged to the Federal Home Loan Bank of Cincinnati securing advances against the Bank’s line. As of June 30, 2018 and December 31, 2017, $1,218,505 and $724,312, respectively, of qualifying loans were pledged to the Federal Reserve Bank under the Borrower-in-Custody program.

As of June 30, 2018 and December 31, 2017, the carrying value of purchased credit impaired loans (“PCI”) loans accounted for under ASC 310-30 Loans and Debt Securities Acquired with Deteriorated Credit Quality, were $78,313 and $88,835, respectively. The following table presents changes in the value of the accretable yield for PCI loans for the periods indicated.

Included in the ending balance in the table above at June 30, 2018, are PCI loans with a purchase accounting liquidity discount of $4,212. There is also a purchase accounting nonaccretable credit discount of $5,236 related to the PCI loan portfolio at June 30, 2018 and an accretable credit and liquidity discount on non-PCI loans of $9,337 and $3,018, respectively.

Interest revenue, through accretion of the difference between the carrying value of the loans and the expected cash flows, is being recognized on all PCI loans. Accretion of interest income amounting to $2,639 and $4,840 was recognized on purchased credit impaired loans during the three and six months ended June 30, 2018, respectively, compared with $589 and $1,612 for the three and six months ended June 30, 2017, respectively. This includes both the contractual interest income and the purchase accounting contribution through accretion of the liquidity discount and credit mark for changes in

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. The Company’s risk rating definitions include:

Watch.    Loans rated as watch includes loans in which management believes conditions have occurred, or may occur, which could result in the loan being downgraded to a worse rated category. Also included in watch are loans rated as special mention, which have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Substandard.    Loans rated as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so rated 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. Also included in this category are loans considered doubtful, which have all the weaknesses previously described and management believes those weaknesses may make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loans not meeting the criteria above are considered to be pass rated loans.

PCI loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement remains unpaid after the due date of the scheduled payment. However, these loans are considered to be performing, even though they may be contractually past due, as any non-payment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or future period yield adjustments. The accrual of interest is discontinued on PCI loans if management can no longer reliably estimate future cash flows on the loan. No PCI loans were classified as nonaccrual at June 30, 2018 or December 31, 2017 as the carrying value of the respective loan or pool of loans cash flows were considered estimable and probable of collection.

Nonperforming loans include loans that are no longer accruing interest (non-accrual loans) and loans past due ninety or more days and still accruing interest. Nonperforming loans and impaired loans are defined differently. Some loans may be included in both categories, whereas other loans may only be included in one category.

There were no TDRs recorded during the three months ended June 30, 2017. Additionally, there were no loans modified as troubled debt restructurings for which there was a payment default within twelve months following the modification during the six months ended June 30, 2018 or 2017.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

The terms of certain other loans were modified during the six months ended June 30, 2018 and 2017 that did not meet the definition of a troubled debt restructuring. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant.

In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the company’s internal underwriting policy.

Note (8)—Commitments and contingencies:

Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates.

Commitments may expire without being used. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment.

	June 30,		December 31,
	2018		2017
Commitments to extend credit, excluding interest rate lock commitments	$	1,088,486	$	977,276

In connection with the sale of mortgage loans to third party investors, the Bank makes usual and customary representations and warranties as to the propriety of its origination activities. Occasionally, the investors require the Bank to repurchase loans sold to them under the terms of the warranties. When this happens, the loans are recorded at fair value with a corresponding charge to a valuation reserve. The total principal amount of loans repurchased (or indemnified for) was $1,543 and $921 and $2,662 and $1,770for the three and six months ended June 30, 2018 and 2017, respectively. The Bank has established a reserve associated with loan repurchases. This reserve is recorded in accrued expenses and other liabilities on the consolidated balance sheet. The following table summarizes the activity in the repurchase reserve:

	For the three months ended						For the six months ended
	June 30,						June 30,
	2018			2017			2018			2017

Note (9)—Derivatives:

The Company utilizes derivative financial instruments as part of its ongoing efforts to manage its interest rate risk exposure as well as the exposure for its customers. Derivative financial instruments are included in the Consolidated Balance Sheets line item “Other assets” or “Other liabilities” at fair value in accordance with ASC 815, “Derivatives and Hedging.”

The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate-lock commitments). Under such commitments, interest rates for a mortgage loan are typically locked in for forty-five days with the customer. These interest rate lock commitments are recorded at fair value in the Company’s Consolidated Balance Sheets.  The Company also enters into best effort or mandatory delivery forward commitments to sell residential mortgage loans to secondary market investors. Gains and losses arising from changes in the valuation of the rate-lock commitments and forward commitments are recognized currently in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income.

The Company enters into forward commitments, futures and options contracts that are not designated as hedging instruments as economic hedges of the change in the fair value of its MSRs. Gains and losses associated with these instruments are included in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income.

The Company enters into derivative instruments that are not designated as hedging instruments to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with customer contracts, the Company enters into an offsetting derivative contract. The Company manages its credit risk, or potential risk of default by its commercial customers through credit limit approval and monitoring procedures.

In June of 2017, the Company entered into two interest rate swap agreements with notional amounts totaling $30,000 to hedge interest rate exposure on outstanding subordinate debentures included in long-term debt totaling $30,930. Under these agreements, the Company receives a variable rate of interest and pays a fixed rate of interest. The interest rate swap contracts, which mature in June of 2024, are designated as cash flow hedges with the objective of reducing the variability in cash flows resulting from changes in interest rates. As of June 30, 2018 and December 31, 2017, the fair value of these contracts was $1,296 and $305, respectively.

In July of 2017, the Company entered into three interest rate swap contracts on floating rate liabilities at the Bank level with notional amounts of $30,000, $35,000 and $35,000 for a period of three, four and five years, respectively. These interest rate swaps were designated as cash flow hedges with the objective of reducing the variability of cash flows associated with $100,000 of FHLB borrowings obtained in conjunction with the Clayton Bank acquisition. Under these contracts, the Company receives a variable rate of interest and pays a fixed rate of interest. As of December 31, 2017, the fair value of these contracts was $1,127 included in those designated as hedging below. During the six months ended June 30, 2018, these swaps were cancelled, locking in a tax-adjusted gain of $1,564 in other comprehensive income to be accreted over the three, four and five-year terms of the underlying contracts. As of June 30, 2018, there was $1,559 remaining in other comprehensive income to be accreted into income.

Certain financial instruments, including derivatives, may be eligible for offset in the Consolidated Balance Sheet when the “right of setoff” exists or when the instruments are subject to an enforceable master netting agreement, which includes the right of the non-defaulting party or non-affected party to offset recognized amounts, including collateral posted with the counterparty, to determine a net receivable or net payable upon early termination of the agreement. Certain of the Company’s derivative instruments are subject to master netting agreements. The Company has not elected to offset such financial instruments in the Consolidated Balance Sheets.

Most derivative contracts with clients are secured by collateral. Additionally, in accordance with the interest rate agreements with derivatives dealers, the Company may be required to post margin to these counterparties. At June 30, 2018 and December 31, 2017, the Company had minimum collateral posting thresholds with certain of its derivative counterparties and posted collateral of $10,896 and $4,309, respectively, against its obligations under these agreements. Cash collateral related to derivative contracts is recorded in other assets in the consolidated balance sheets.

Note (10)—Fair value of financial instruments:

FASB ASC 820-10 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820-10 also establishes a framework for measuring the fair value of assets and liabilities according to a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that are derived from assumptions based on management’s estimate of assumptions that market participants would use in pricing the asset or liability based on the best information available under the circumstances.

The hierarchy is broken down into the following three levels, based on the reliability of inputs:

Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs for assets or liabilities that are derived from assumptions based on management’s estimate of assumptions that market participants would use in pricing the assets or liabilities.    

The Company records the fair values of financial assets and liabilities on a recurring and non-recurring basis using the following methods and assumptions:

During the first quarter of 2018, the Company adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.” The amendments included within this standard, which are applied prospectively, require the Company to disclose fair value of financial instruments measured at amortized cost on the balance sheet to measure the fair value using an exit price notion. Prior to adopting the amendments included in the standard, the Company measured fair value under an entry price notion.

Investment securities—Investment securities are recorded at fair value on a recurring basis. Fair values for securities are based on quoted market prices, where available. If quoted prices are not available, fair values are based on quoted market prices of similar instruments or are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the pricing relationship or correlation among other benchmark quoted securities. Investment securities valued using quoted market prices of similar instruments or that are valued using matrix pricing are classified as Level 2. When significant inputs to the valuation are unobservable, the available-for-sale securities are classified within Level 3 of the fair value hierarchy.

Where no active market exists for a security or other benchmark securities, fair value is estimated by the Company with reference to discount margins for other high risk securities.

Loans held for sale—Loans held for sale are carried at fair value. Fair value is determined using current secondary market prices for loans with similar characteristics, that is, using Level 2 inputs.

Derivatives—The fair value of the interest rate swaps are based upon fair values provided from entities that engage in interest rate swap activity and is based upon projected future cash flows and interest rates. Fair value of commitments is based on fees currently charged to enter into similar agreements, and for fixed-rate commitments, the difference between current levels of interest rates and the committed rates is also considered. These financial instruments are classified as Level 2.

Other real estate owned—Other real estate owned (“OREO”) is comprised of commercial and residential real estate obtained in partial or total satisfaction of loan obligations and excess land and facilities held for sale. OREO acquired in settlement of indebtedness is recorded at the lower of the carrying amount of the loan or the fair value of the real estate less costs to sell. Fair value is determined on a nonrecurring basis based on appraisals by qualified licensed appraisers

(Amounts are in thousands except share and per share amounts)

and is adjusted for management’s estimates of costs to sell and holding period discounts. The valuations are classified as Level 3.

Mortgage servicing rights—Servicing rights are carried at fair value. Fair value is determined using an income approach with various assumptions including expected cash flows, market discount rates, prepayment speeds, servicing costs, and other factors. Mortgage servicing rights are disclosed as Level 3.

Impaired loans—Loans considered impaired under FASB ASC 310, Receivables, are loans for which, based on current information and events, it is probable that the creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. Fair value adjustments for impaired loans are recorded on a non-recurring basis as either partial write downs based on observable market prices or current appraisal of the collateral. Impaired loans are classified as Level 3.

The following table contains the estimated fair values and the related carrying values of the Company's financial instruments. Items which are not financial instruments are not included. Due to the adoption of ASU 2016-01 as of January 1, 2018, the fair value as presented below is measured using the exit price notion in the periods after adoption and may not be comparable with prior periods presented as a result of the change in methodology.

(1) See Note 1, “Basis of Presentation” in the Notes to the consolidated financial statements for additional details regarding the adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities.

As of December 31, 2017, there was no established market for certain other securities, and as such, the Company had estimated that historical costs approximated market value. As of January 1, 2018, the Company adopted ASU 2016-01 (See Note 1) and reclassified $3,604 of these other securities without readily determinable market values to other assets.

The following table presents information as of June 30, 2018 about significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis:

The following table presents information as of December 31, 2017 about significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis:

Financial instrument	FairValue		Valuation technique	Significant Unobservable inputs	Range of inputs
Impaired loans	$	77,027	Valuation of collateral	Discount for comparable sales	0%-30%
Other real estate owned	$	13,174	Appraised value of property less costs to sell	Discount for costs to sell	0%-15%

Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the lending administrative department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry wide statistics.

Fair value option:

The Company elected to measure all loans originated for sale at fair value under the fair value option as permitted under ASC 825. Electing to measure these assets at fair value reduces certain timing differences and better matches the changes in fair value of the loans with changes in the fair value of derivative instruments used to economically hedge them.

Net gains of $2,076 and $4,197 and $1,864 and $9,470 and resulting from fair value changes of the mortgage loans were recorded in income during the three and six months ended June 30, 2018 and 2017, respectively. The amount does not reflect changes in fair values of related derivative instruments used to hedge exposure to market-related risks associated with these mortgage loans. The change in fair value of both loans held for sale and the related derivative instruments are recorded in Mortgage Banking Income in the Consolidated Statements of Income. Election of the fair value option allows the Company to reduce the accounting volatility that would otherwise result from the asymmetry created by accounting for the financial instruments at the lower of cost or fair value and the derivatives at fair value. The fair value option election does not apply to the GNMA optional repurchase loans recorded as of December 31, 2017 which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option. At June 30, 2018, there were $52,212 of delinquent GNMA loans that had previously been sold. The Company determined there not to be a more-than-trivial benefit based on an analysis of interest rates and an assessment of potential reputational risk associated with these loans. As such, the Company had $0 in rebooked GNMA loans included in loans held for sale as of June 30, 2018. GNMA optional repurchase loans totaled $43,035 at December 31, 2017 and are included in loans held for sale on the accompanying Consolidated Balance Sheet. See Note 1, “Basis of presentation” in the Notes to the consolidated financial statements for additional details regarding rebooked GNMA loans.

The Company’s valuation of loans held for sale incorporates an assumption for credit risk; however, given the short-term period that the Company holds these loans, valuation adjustments attributable to instrument-specific credit risk is nominal. Interest income on loans held for sale measured at fair value is accrued as it is earned based on contractual rates and is reflected in loan interest income in the Consolidated Statements of Income.

Note (11)—Segment reporting:

The Company and the Bank are engaged in the business of banking and provide a full range of financial services. The Company determines reportable segments based on the significance of the segment’s operating results to the overall Company, the products and services offered, customer characteristics, processes and service delivery of the segments and the regular financial performance review and allocation of resources by the Chief Executive Officer (“CEO”), the Company’s chief operating decision maker. The Company has identified two distinct reportable segments—Banking and Mortgage. The Company’s primary segment is Banking, which provides a full range of deposit and lending products and services to corporate, commercial and consumer customers. The Company offers full-service conforming residential mortgage products, including conforming residential loans and services through the Mortgage segment utilizing mortgage offices outside of the geographic footprint of the Banking operations as well as internet and correspondent delivery channels. Additionally, the Mortgage Segment includes the servicing of residential retail mortgage loans and the packaging and securitization of loans to governmental agencies. The residential mortgage products and services originated in our Banking footprint and related revenues and expenses are included in our Banking segment. The Company’s mortgage division represents a distinct reportable segment which differs from the Company’s primary business of commercial and retail banking.

The financial performance of the Mortgage segment is assessed based on results of operations reflecting direct revenues and expenses and allocated expenses. This approach gives management a better indication of the operating performance of the segment. When assessing the Banking segment’s financial performance, the CEO utilizes reports with indirect revenues and expenses including but not limited to the investment portfolio, electronic delivery channels and areas that primarily support the banking segment operations.  Therefore, these are included in the results of the Banking segment. Other indirect revenue and expenses related to general administrative areas are also included in the internal financial results reports of the Banking segment utilized by the CEO for analysis and are thus included for Banking segment reporting. The Mortgage segment utilizes funding sources from the Banking segment in order to fund mortgage loans that are ultimately sold on the secondary market. The Mortgage segment uses the proceeds from loan sales to repay obligations due to the Banking segment.

Note (12)—Minimum capital requirements:

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

Under regulatory guidance for non-advanced approaches institutions, the Bank is required to maintain minimum amounts and ratios of common equity Tier I capital to risk-weighted assets. Additionally, under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. As of June 30, 2018 and December 31, 2017, the Bank and Company met all capital adequacy requirements to which it is subject. Also, as of June 30, 2018, the most recent notification from the Federal Deposit Insurance Corporation (“FDIC”), the Bank was well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category.

Beginning in 2016, an additional conservation buffer was added to the minimum requirements for capital adequacy purposes, subject to a three year phase-in period. As of June 30, 2018 and December 31, 2017, the buffer was 1.75 percent and 1.25 percent, respectively. The capital conservative buffer will be fully phased in January 1, 2019 at 2.5 percent.

Actual and required capital amounts and ratios are presented below at period-end:

Note (13)—Stock-Based Compensation:

The Company granted shares of common stock and restricted stock units as a part of its initial public offering and compensation arrangements for the benefit of employees, executive officers, and directors. Restricted stock unit grants are subject to time-based vesting. The total number of restricted stock units granted represents the maximum number of restricted stock units eligible to vest based upon the service conditions set forth in the grant agreements.

Following the initial public offering, participants in the EBI Plans were given the option to elect conversion of their outstanding cash-settled EBI Units to stock-settled EBI Units. At June 30, 2018 and December 31, 2017, there were 29,172 and 67,470 units valued at $1,188 and $2,833, respectively, outstanding under the equity based incentive plans for employees who elected cash settlement of EBI units. Expense related to the cash settled EBI was $102 and $219 for the three and six months ended June 30, 2018, respectively, and $184 and $482 for the three and six months ended June 30, 2017, respectively.

The following table summarizes information about vested and unvested restricted stock units, excluding cash-settled EBI units discussed above, outstanding at June 30, 2018 and 2017:

	Six Months Ended June 30,

Cautionary note regarding forward-looking statements

Certain statements contained in this Report are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements include, without limitation, statements relating to the Company’s assets business, cash flows, condition (financial or otherwise), credit quality, financial performance, liquidity, short and long-term performance goals, prospects, results of operations, strategic initiatives, the benefits, cost and synergies of the Clayton Banks acquisition, and the timing, benefits, costs and synergies of future acquisitions, disposition and other growth opportunities. These statements, which are based upon certain assumptions and estimates and describe the Company’s future plans, results, strategies and expectations, can generally be identified by the use of the words and phrases “may,” “will,” “should,” “could,” “would,” “goal,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target,” “aim,” “predict,” “continue,” “seek,” “projection” and other variations of such words and phrases and similar expressions. These forward-looking statements are not historical facts, and are based upon current expectations, estimates and projections about the Company’s industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond the Company’s control. The inclusion of these forward-looking statements should not be regarded as a representation by the Company or any other person that such expectations, estimates and projections will be achieved. Accordingly, the Company cautions investors that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict and that are beyond the Company’s control. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable as of the date of this Report, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this Report including, without limitation, the risks and other factors set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on March 16, 2018 under the captions “Cautionary note regarding forward-looking statements” and “Risk factors.” Many of these factors are beyond the Company’s ability to control or predict. If one or more events related to these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, actual results may differ materially from the forward-looking statements. Accordingly, investors should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this Report, and the Company does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for the Company to predict their occurrence or how they will affect the Company.

Because of these risks and other uncertainties, our actual results, performance or achievement, or industry results, may be materially different from the anticipated or estimated results discussed in the forward-looking statements in this Report.  Our past results of operations are not necessarily indicative of our future results. You should not unduly rely on any forward-looking statements, which represent our beliefs, assumptions and estimates only as of the dates on which they were made, as predictions of future events. We undertake no obligation to update these forward-looking statements as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for us to predict their occurrence or how they will affect us.

We qualify all of our forward-looking statements by these cautionary statements.

Critical accounting policies

Our financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and general practices within the banking industry.  Within our financial statements, certain financial information contains approximate measurements of financial effects of transactions and impacts at the consolidated balance sheet dates and our results of operations for the reporting periods.  As certain accounting policies require significant estimates and assumptions that have a material impact on the carrying value of assets and liabilities, we have established critical accounting policies to facilitate making the judgments necessary to prepare our financial statements.  Our critical accounting policies are described in our Annual Report under the captions “Item 7 – Management’s discussion and

analysis of financial condition and results of operations – Critical accounting policies” and “Item 8 – Financial Statement and Supplementary Data – Notes to consolidated financial statements.” Subsequent adoptions are further described in “Part I. Financial Information – Notes to Consolidated Financial Statements” of this Report.

Overview

We are a bank holding company headquartered in Nashville, Tennessee. We operate primarily through our wholly owned bank subsidiary, FirstBank, the third largest bank headquartered in Tennessee, based on total assets. FirstBank provides a comprehensive suite of commercial and consumer banking services to clients in select markets in Tennessee, North Alabama, and North Georgia. At June 30, 2018, our footprint included 56 full-service bank branches serving the following Metropolitan Statistical Areas (“MSAs”): Nashville, Chattanooga (including North Georgia), Knoxville, Memphis, Jackson, and Huntsville, Alabama and 12 community markets throughout Tennessee. FirstBank also provides mortgage banking services utilizing its bank branch network and mortgage banking offices strategically located throughout the southeastern United States and a national internet delivery channel.

We operate through two segments, Banking and Mortgage. We generate most of our revenue in our Banking segment from interest on loans and investments, loan-related fees, mortgage originations within our banking footprint, trust and investment services and deposit-related fees. We generate most of our revenue in our Mortgage segment from origination fees and gains on sales in the secondary market of mortgage loans that we originate outside our Banking footprint or through our internet delivery channels, from wholesale and third party origination services, and from servicing these mortgage loans. Our primary source of funding for our loans is customer deposits, and, to a lesser extent, Federal Home Loan Bank advances, brokered and internet deposits, and other borrowings.

(1) Book value per share equals our total shareholders’ equity as of the date presented divided by the number of shares of our common stock outstanding as of the date presented. The number of shares of our common stock outstanding as of June 30, 2018 and 2017 was 30,683,353and 28,968,160, respectively, and 30,535,517 as of December 31, 2017.

(2) We have calculated our return on average assets and return on average equity for a period by dividing net income for that period by our average assets and average equity, as the case may be, for that period. We calculate our average assets and average equity for a period by dividing the sum of our total asset balance or total shareholder’s equity balance, as the case may be, as of the close of business on each day in the relevant period and dividing by the number of days in the period.

(3) We calculate our risk-weighted assets using the standardized method of the Basel III Framework for all periods, as implemented by the Federal Reserve and the FDIC.

(4) These measures are not measures prepared in accordance with GAAP, and are therefore considered to be non-GAAP financial measures. See “GAAP reconciliation and management explanation of non-GAAP financial measures” for a reconciliation of these measures to their most comparable GAAP measures.

GAAP reconciliation and management explanation of non-GAAP financial measures

We identify certain financial measures discussed in this Report as being “non-GAAP financial measures.” The non-GAAP financial measures presented in this Report are adjusted efficiency ratio (tax-equivalent basis), tangible book value per common stock and tangible common equity to tangible assets.

In accordance with the SEC’s rules, we classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows.

The non-GAAP financial measures that we discuss in this Report should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures that we discuss in our selected historical consolidated financial data may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures we have presented in our selected historical consolidated financial data when comparing such non-GAAP financial measures. The following discussion and reconciliations provide a more detailed analysis of these non-GAAP financial measures.

Adjusted efficiency ratio (tax-equivalent basis)

The adjusted efficiency ratio (tax-equivalent basis) is a non-GAAP measure that excludes securities gains (losses), merger-related and conversion expenses, one time Initial Public Offering (“IPO”) equity grants and other selected items. Our management uses this measure in its analysis of our performance. Our management believes this measure provides a greater understanding of ongoing operations and enhances comparability of results with prior periods, as well as demonstrates the effects of significant gains and charges. The most directly comparable financial measure calculated in accordance with GAAP is the efficiency ratio.

The following table presents, as of the dates set forth below, a reconciliation of our adjusted efficiency ratio (tax-equivalent basis) to our efficiency ratio:

Tangible book value per common stock and tangible common equity to tangible assets

Tangible book value per common stock and tangible common equity to tangible assets are non-GAAP measures that exclude the impact of goodwill and other intangibles used by the Company’s management to evaluate capital adequacy.  Because intangible assets such as goodwill and other intangibles vary extensively from company to company, we believe

46

that the presentation of this information allows investors to more easily compare the Company’s capital position to other companies.  The most directly comparable financial measures calculated in accordance with GAAP are book value per common stock and our total shareholders’ equity to total assets.

The following table presents, as of the dates set forth below, reconciliations of our tangible common equity to our total shareholders’ equity, our tangible book value per share to our book value per share and our tangible common equity to tangible assets to our total shareholders’ equity to total assets:

Mergers and acquisitions

Clayton Bank and Trust and American City Bank

Effective July 31, 2017, the Company and FirstBank completed the previously announced merger with Clayton Bank and Trust (“CBT”) and American City Bank (“ACB” and together with CBT, the “Clayton Banks”), pursuant to the Stock Purchase Agreement dated February 8, 2017, as amended on May 26, 2017, with Clayton HC, Inc., a Tennessee Corporation (“Seller”), and James L. Clayton, the majority shareholder of Seller. The transaction was valued at approximately $236.5 million. The Company issued 1,521,200 shares of common stock and paid approximately $184.2million to purchase all of the outstanding shares of the Clayton Banks. At closing, the Clayton Banks merged with and into FirstBank, with FirstBank continuing as the surviving banking corporation. After finalizing purchase accounting adjustments, the Clayton Banks merger added approximately $1,215.8million in total assets, $1,059.7million in loans, and $979.5million in deposits. Operating results for the three and six months ended June 30, 2018 include the operating results of the acquired assets and assumed liabilities of the Clayton Banks. Substantially all of the operations of the Clayton Banks are included in the Banking segment. We incurred merger and conversion expenses connected with this transaction amounting to $0and $1.2 million during the three and six months ended June 30, 2018, respectively, and $0.8million and $1.3 million during the three and six months ended June 30, 2017, respectively.

Factors affecting comparability of financial results

Tax legislation changes

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Reform Act”) was enacted into law. The Tax Reform Act provides for significant changes to the U.S. tax code that impact businesses. Effective January 1, 2018, the Tax Reform Act reduces the U.S. federal tax rate for corporations from 35% to 21% for U.S. taxable income and requires a one-time remeasurement of deferred taxes to reflect their value at a lower tax rate of 21%. The Tax Reform Act includes other changes, including, but not limited to, immediate deductions for certain new investments instead of deductions for depreciation expense over time, additional limitations on the deductibility of executive compensation and limitations on the deductibility of interest. For more information regarding the impact of the Tax Reform Act on the Company, see Note 15, “Income Taxes” in the notes to our consolidated financial statements on Form 10-K filed with the SEC on March 16, 2018.

Overview of recent financial performance

Results of operations

For the three months ended June 30, 2018, net income was $22.1 million compared to $11.2 million in the three months ended June 30, 2017. Pre-tax income was $29.9 million in the three months ended June 30, 2018 compared with $17.8 million in the same period in 2017. Diluted earnings per common share were $0.70 and $0.43 for the three months ended June 30, 2018 and 2017, respectively. Our net income represented a ROAA of 1.86% and 1.40% for the three months ended June 30, 2018 and 2017, respectively, and a ROAE of 14.4% and 11.3% for the same periods. Our ratio of average shareholders’ equity to average assets in the three months ended June 30, 2018 and 2017 was 12.9% and 12.4%, respectively.

For the six months ended June 30, 2018, net income was $41.8 million compared to $21.0 million in the six months ended June 30, 2017. Pre-tax income was $55.1 million in the six months ended June 30, 2018 compared with $33.0 million in the same period in 2017. Diluted earnings per common share were $1.33 and $0.82 for the six months ended June 30, 2018 and 2017, respectively. Our net income represented a ROAA of 1.79% and 1.32% for the six months ended June 30, 2018 and 2017, respectively, and a ROAE of 13.9% and 11.6% for the same periods. Our ratio of average shareholders’ equity to average assets in the six months ended June 30, 2018 and 2017 was 12.9% and 11.4%, respectively.

During the three months ended June 30, 2018, net interest income increased to $51.5 million compared to $30.4 million in the three months ended June 30, 2017, which was attributable to an increase in interest income and expense, primarily driven by loan and deposit growth, including the added loan and deposits resulting from the Clayton Banks merger. Our net interest margin, on a tax-equivalent basis, increased to 4.81% for the three months ended June 30, 2018 as compared to 4.19% for the three months ended June 30, 2017, due primarily to the increase in contractual loan yield and fees earned on our loan portfolio while controlling our cost of funds. Noninterest income remained relatively flat for the three months ended June 30, 2018, increasing by $0.1 million to $35.8 million from the same period in the previous year.

48

Noninterest expense increased to $56.4 million for the three months ended June 30, 2018 compared to $49.1 million for the three months ended June 30, 2017. The increase was a result of our overall growth and added operational cost resulting from the merger with the Clayton Banks, in addition to increases in personnel costs associated with our growth.

During the six months ended June 30, 2018, net interest income increased to $99.9 million compared to $60.7 million in the six months ended June 30, 2017, which was attributable to an increase in interest income and expense, primarily driven by loan and deposit growth resulting from the Clayton Banks merger. Our net interest margin, on a tax-equivalent basis, increased to 4.73% for the six months ended June 30, 2018 as compared to 4.24% for the six months ended June 30, 2017 due to loan and deposit growth, including the impact of the product mix acquired from the Clayton Banks, in addition to increased contractual loan yield and fees during the period. Noninterest income for the six months ended June 30, 2018 increased by $2.3 million to $69.0 million from the same period in the previous year primarily due to increased volume of business and our merger with the Clayton Banks.

Noninterest expense also increased to $112.5 million for the six months ended June 30, 2018 compared to $95.6 million for the six months ended June 30, 2017.  The increase was a result of our overall growth and added operational costs resulting from the merger with the Clayton Banks in addition to increases in personnel costs associated with our growth.

Financial condition

Our total assets increased to $4.92 billion at June 30, 2018 as compared to $4.73 billion at December 31, 2017. Loans held for investment increased $248.7 million to $3.42 billion, offset by a decline in loans held for sale of $151.3 million to $374.9 million at June 30, 2018.

We grew total deposits by $245.5 million to $3.91 billion at June 30, 2018 as compared to $3.66 billion at December 31, 2017. Noninterest bearing deposits as a percentage of total deposits was 24.8% at June 30, 2018 compared to 24.2% at December 31, 2017.

Business segment highlights

We operate our business in two business segments: Banking and Mortgage. See “Part I. Financial Information – Notes to Consolidated Financial Statements – Note (11) – Segment reporting” in this Report.

Banking

Income before taxes increased by $13.9 million, or 98.7%, in the three months ended June 30, 2018 to $27.9 million as compared to $14.1 million in the three months ended June 30, 2017 due primarily to increased net interest income of $21.7 million resulting from an increase of $1.3 billion in average loan balances attributable to our growth, including the impact of the merger with the Clayton Banks, combined with rising interest rates. This was partially offset by increased noninterest expense of $7.4 million associated with our growth, including personnel costs resulting from our increased volume of business.

Income before taxes from the Banking segment increased by $25.0 million, or 92.1%, in the six months ended June 30, 2018 to $52.1 million as compared to $27.1 million in the six months ended June 30, 2017. The increase reflects an improvement of $40.6 million in net interest income due to an increase of $1.3 billion in average loan balances driven by our growth including the impact of our merger with the Clayton Banks combined with favorable interest rates and a continuing strong credit environment. Noninterest expense increased $15.9 million, primarily due to increased costs associated with our growth including personnel costs and operational costs resulting from our merger with the Clayton Banks.

Mortgage

Income before taxes from the Mortgage segment decreased 48.9% in the three months ended June 30, 2018 to $1.9 million as compared to $3.7 million in the three months ended June 30, 2017 primarily due to a decrease in noninterest income. Noninterest income decreased $1.5 million to $21.7 million for the three months ended June 30, 2018 as compared to $23.1 million for the three months ended June 30, 2017, driven by decreased interest rate lock commitment volume during the period. Interest rate lock commitment volume decreased $181.6million, or 8.4%, during the three months ended June 30, 2018 due to higher interest rates and overall slow down in the mortgage market. The change in fair value on MSRs and related hedging activities included in mortgage banking income amounted to a loss of $1.8 million mainly due to decay during the three months ended June 30, 2018. Decay exists regardless of MSR hedging activity and is due to the natural aging and paydown of the mortgage servicing portfolio with the payments from customers more than offsetting the decay, resulting in positive gross servicing income of $3.8 million. This compares to a decline in fair value on MSRs and gross servicing income of $1.8million and $0.9 million, respectively for the three months ended

49

June 30, 2017. The asset was not hedged during the three and six months ended June 30, 2017. Interest rate lock commitments in the pipeline at June 30, 2018 were $597.6 million compared with $546.5 million at June 30, 2017 and $504.2 million at December 31, 2017. Noninterest expense declined $0.2 million to $19.6 million for the three months ended June 30, 2018, primarily due to the loss of $0.2 million included in the three months ended June 30, 2017. There were no such sales during the three months ended June 30, 2018.

Income before taxes from the Mortgage segment declined $2.9 million in the six months ended June 30, 2018 to $3.0 million as compared to $5.9 million in the six months ended June 30, 2017. While interest rate lock commitment volume increased $349.2 million for the six months ended June 30, 2018 to $4,105.0 million as compared to $3,755.8 million for the six months ended June 30, 2017, noninterest income decreased $0.5 million to $42.0 million for the six months ended June 30, 2018 as compared to $42.5 million for the six months ended June 30, 2017 driven by a change in the delivery channel mix and overall compressing margins experienced across the market. Noninterest income for the six months ended June 30, 2018 also included a $3.5million charge related to the change in fair value of the MSRs and related hedging activity. This compares to a $2.3 million charge related to the change in fair value of the MSRs during the six months ended June 30, 2017. Noninterest expense for the six months ended June 30, 2018 and 2017 was $38.5 million and $37.5 million, respectively.

Results of operations

Throughout the following discussion of our operating results, we present our net interest income, net interest margin and efficiency ratio on a fully tax-equivalent basis. The fully tax-equivalent basis adjusts for the tax-favored status of net interest income from certain loans and investments. We believe this measure to be the preferred industry measurement of net interest income, which enhances comparability of net interest income arising from taxable and tax-exempt sources. The adjustment to convert certain income to a tax-equivalent basis consists of dividing tax exempt income by one minus the combined federal and blended state statutory income tax rate of 26.06% and 39.23% for the three months ended June 30, 2018 and 2017.

Net interest income

Our net interest income is primarily affected by the interest rate environment and by the volume and the composition of our interest-earning assets and interest-bearing liabilities. We utilize net interest margin (“NIM”) which represents net interest income, on a tax-equivalent basis, divided by average interest-earning assets, to track the performance of our investing and lending activities. We earn interest income from interest, dividends and fees earned on interest-earning assets, as well as from amortization and accretion of discounts on acquired loans. Our interest-earning assets include loans, time deposits in other financial institutions and securities available for sale. We incur interest expense on interest-bearing liabilities, including interest-bearing deposits, borrowings and other forms of indebtedness as well as from amortization of premiums on purchased deposits. Our interest-bearing liabilities include deposits, advances from the FHLB, repurchase agreements and subordinated debt.

Three months ended June 30, 2018 compared to three months ended June 30, 2017

Net interest income increased 69.3% to $51.5 million in the three months ended June 30, 2018 compared to $30.4 million in the three months ended June 30, 2017. On a tax-equivalent basis, net interest income increased $20.8 million to $51.9 million in the three months ended June 30, 2018 as compared to $31.2 million in the three months ended June 30, 2017. The increase in tax-equivalent net interest income in the three months ended June 30, 2018 was primarily driven by increased volume and rates on loans held for investment resulting in a $25.2million increase in interest income from loans held for investment.

Interest income, on a tax-equivalent basis, was $59.4 million for the three months ended June 30, 2018, compared to $34.0 million for the three months ended June 30, 2017, an increase of $25.4 million. The two largest components of interest income are loan income and investment income. Loan income consists primarily of interest earned on our loans held for investment portfolio in addition to loans held for sale. Investment income consists primarily of interest earned on our investment portfolio. Loan income on loans held for investment, on a tax-equivalent basis, increased $25.2 million to $50.2 million from $25.0 million for the three months ended June 30, 2018 and 2017, respectively, primarily due to increased average loan balances of $1,346.4 million. The tax-equivalent yield on loans held for investment was 6.12%, up 93 basis points from the three months ended June 30, 2017. The increase in yield was primarily due to increased contractual interest rates and loan fees which yielded 5.37% and 0.46%, respectively, in the three months ended June 30, 2018 compared with 4.63% and 0.30%, respectively, during the three months ended June 30, 2017. Also included in the loan yield is the purchase accounting contribution of accretion and nonaccrual interest collections, which yielded 0.23% and 0.03%, respectively, in the three months ended June 30, 2018 compared with 0.17% and 0.07%, respectively, in the three  months ended June 30, 2017.

50

The components of our loan yield, a key driver to our NIM for the three months ended June 30, 2018 and 2017, were as follows:

	Three Months Ended June 30, 2018					Three Months Ended June 30, 2017
(dollars in thousands)	Interest income		Average yield			Interest income		Average yield
Loan yield components:
Contractual interest rate on loans held for    investment(1)	$	44,057		5.37	%	$	22,418		4.63	%
Origination and other loan fee income		3,742		0.46	%		1,447		0.30	%
Accretion on purchased loans		1,928		0.23	%		848		0.17	%
Nonaccrual interest collections		250		0.03	%		315		0.07	%
Syndicated fee income		216		0.03	%		87		0.02	%
Total loan yield	$	50,193		6.12	%	$	25,115		5.19	%

(1) Includes tax-equivalent adjustment

Accretion on purchased loans contributed 18 basis points and 11 basis points to the NIM for the three months ended June 30, 2018 and 2017, respectively. Additionally, nonaccrual interest income contributed 2 basis points and 4 basis points and syndicated loan fees contributed 2 and 1 basis points to the NIM for the three months ended June 30, 2018 and 2017, respectively.

For the three months ended June 30, 2018, interest income on loans held for sale remained flat at $4.4 million compared to the three months ended June 30, 2017 due to an increase in rates contributing $0.4 million offset by a decrease in volume of $0.3 million. For the three months ended June 30, 2018, investment income, on a tax-equivalent basis, increased slightly to $4.5 million for the three months ended June 30, 2018 compared to $4.3 million for the three months ended June 30, 2017. The average balance in the investment portfolio for the three months ended June 30, 2018 was $599.4 million compared to $564.9 million in the three months ended June 30, 2017.

Interest expense was $7.5 million for the three months ended June 30, 2018, an increase of $4.7 million compared to the three months ended June 30, 2017. The increase in interest expense was primarily due to increased cost of deposits and interest rate increases in FHLB advances. Anticipated increases in federal funds rates in the second half of 2018 are expected to continue to drive up our cost of funds and apply compression to our NIM. The current period increase in deposit cost was driven by overall increased interest rates and growth in deposit volume driven by our growth, including our merger with the Clayton Banks. Interest expense on deposits was $5.9 million and $2.3 million for the three months ended June 30, 2018 and 2017, respectively. The cost of total deposits was 0.62% and 0.34% for the three months ended June 30, 2018 and 2017, respectively while the cost of interest-bearing deposits was 0.84% and 0.47% for the same periods. The primary driver for the increase in total interest expense is the increase in money market and time deposit interest expense to $2.3 million and $1.9 million, respectively, for the three months ended June 30, 2018 from $0.9 million and $0.6 million, respectively, for the three months ended June 30, 2017 driven by an increase in rate and balances. The rate on money markets was 0.92%, up 43 basis points from the three months ended June 30, 2017. Time deposit interest expense also increased $1.3 million from the three months ended June 30, 2017 driven by increased rates and average time deposit balances, which increased $313.5 million to $704.4 million during the three months ended June 30, 2018 from $390.9 million for the same period in the previous year.  The rate on total time deposits was 1.11%, up 49 basis points from the three months ended June 30, 2017. The increase is partially due to a change in product mix attributable to our merger with the Clayton Banks, which increased average brokered and internet time deposits by $74.3 million during the three months ended June 30, 2018 compared to the same period in 2017. Brokered and internet time deposits carry an inherently higher rate at 1.64% for the three months ended June 30, 2018 than traditional customer time deposits. Our customer time deposits carried a rate of 1.04% during the three months ended June 30, 2018 compared to 0.62% in the same period in the previous year, reflecting the rising rate environment. Interest expense on borrowings was $1.6 million and $0.5 million for the three months ended June 30, 2018 and 2017, respectively, while the cost of total borrowings was 2.15% and 2.16% for the three months ended June 30, 2018 and 2017, respectively. For more information about our borrowings, refer to the discussion in this section under the heading “Financial condition: Borrowed funds.”

Our NIM, on a tax-equivalent basis, increased to 4.81% during the three months ended June 30, 2018 from 4.19% in the three months ended June 30, 2017, primarily a result of increased contractual loan yield while controlling our cost of funds in an increasing rate environment.

Six months ended June 30, 2018 compared to six months ended June 30, 2017

Net interest income increased 64.7% to $99.9 million in the six months ended June 30, 2018 compared to $60.7 million in the six months ended June 30, 2017. On a tax-equivalent basis, net interest income increased $38.6 million to $100.7 million in the six months ended June 30, 2018 as compared to $62.1 million in the six months ended June 30, 2017. The increase in tax-equivalent net interest income in the six months ended June 30, 2018 was primarily driven by increased volume and rates in loans held for investment offset by an increase in deposit volume and rates, both partially driven by the product mix acquired from our merger with the Clayton Banks.  

Interest income, on a tax-equivalent basis, was $114.7 million for the six months ended June 30, 2018, compared to $67.6 million for the six months ended June 30, 2017, an increase of $47.0 million. The two largest components of interest income are loan income and investment income. Loan income consists primarily of interest earned on our loans held for investment portfolio and loans held for sale. Investment income consists primarily of interest earned on our investment portfolio. Interest income on loans held for investment, on a tax-equivalent basis, increased $46.7 million to $96.8 million for the six months ended June 30, 2018 from $50.0 million for the six months ended June 30, 2017 primarily due to increased average loan balances of $1,335.1 million. The tax-equivalent yield on loans was 6.02%, up 73 basis points from the six months ended June 30, 2017. The increase in yield was primarily due to increased contractual interest rates and loan fees which yielded 5.33% and 0.41%, respectively, in the six months ended June 30, 2018 compared with 4.57% and 0.36% during the six months ended June 30, 2017, respectively. Also included in the loan yield is the purchase accounting contribution of accretion and nonaccrual interest collections, which yielded 0.22% and 0.04%, respectively, in the six months ended June 30, 2018 compared with 0.21% and 0.10%, respectively, in the six months ended June 30, 2017.

The components of our loan yield, a key driver to our NIM for the six months ended June 30, 2018 and 2017, were as follows:

	Six Months Ended June 30, 2018					Six Months Ended June 30, 2017
(dollars in thousands)	Interest income		Average yield			Interest income		Average yield
Loan yield components:
Contractual interest rate on loans held for    investment(1)	$	85,593		5.33	%	$	43,257		4.57	%
Origination and other loan fee income		6,609		0.41	%		3,384		0.36	%
Accretion on purchased loans		3,615		0.22	%		2,008		0.21	%
Nonaccrual interest collections		649		0.04	%		934		0.10	%
Syndicated loan fee income		291		0.02	%		440		0.05	%
Total loan yield	$	96,757		6.02	%	$	50,023		5.29	%

(1) Includes tax-equivalent adjustment

Accretion on purchased loans contributed 17 and 14 basis points to the NIM for the six months ended June 30, 2018 and 2017, respectively. Additionally, nonaccrual interest collections and syndicated loan fees contributed 3 and 1 basis points, respectively, to the NIM for the six months ended June 30, 2018 compared to 6 and 3 basis points, respectively, to the NIM for the six months ended June 30, 2017.

For the six months ended June 30, 2018, interest income on loans held for investment increased $46.7 million to $96.8 million as a result of increases in volume and rates partially driven by the product mix acquired in our merger with the Clayton Banks. For the six months ended June 30, 2018, interest income on loans held for sale increased $0.1 million to $8.6 million compared to the six months ended June 30, 2017. This resulted from a decrease in rates of $0.1 million and growth in volume of $0.3 million. Investment income, on a tax-equivalent basis, remained flat at $8.6 million for the six months ended June 30, 2018 and 2017. The average balance in the investment portfolio in the six months ended June 30, 2018 was $582.9 million compared to $569.5 million in the six months ended June 30, 2017.

Interest expense was $13.9 million for the six months ended June 30, 2018, an increase of $8.5 million as compared to the six months ended June 30, 2017. The increase in interest expense was due to an increase in deposit interest expense and interest rate increases on FHLB advances. The increase in deposit cost was driven by overall increased interest rates and growth in deposit volume driven by our merger with the Clayton Banks. Interest expense on deposits was $11.0 million and $4.4 million for the six months ended June 30, 2018 and 2017, respectively. The cost of total deposits was 0.59% and 0.33% for the six months ended June 30, 2018 and 2017, respectively. The cost of interest-bearing deposits was 0.79% and 0.45% for the same periods, respectively. The primary driver for the increase in total interest expense is the increase in money market and time deposit interest expense to $4.2 million and $3.7 million, respectively, from $1.7 million and $1.2 million, respectively, for the six months ended June 30, 2018 and 2017, respectively, driven by an

53

increase in rates and balances. The rate on money markets was 0.86%, up 39 basis points from six months ended June 30, 2017. Time deposit interest expense also increased $2.5 million to $3.7 million from the six months ended June 30, 2017, also as a result of an increase in rates and balances. The rate on time deposits was 1.06%, up 45 basis points from the six months ended June 30, 2017. Average time deposit balances increased $312.6 million to $703.2 million from $390.6 million during the six months ended June 30, 2018. The increase in time deposits from June 30, 2017 is a result of the merger with the Clayton Banks, which contributed to the $78.4 million increase in average brokered and internet time deposits and carry an inherently higher rate at 1.62% during the six months ended June 30, 2018 than our traditional customer time deposits. Our customer time deposits carried a rate of 0.99% during the six months ended June 30, 2018 compared to 0.61% for the same period in the previous year. Interest expense on borrowings was $3.0 and $1.1 million for the six months ended June 30, 2018 and 2017, respectively, while the cost of total borrowings was 2.14% and 2.04% for the six months ended June 30, 2018 and 2017, respectively, reflecting increased FHLB advances, the proceeds of which were used to fund the merger with the Clayton Banks.

Our NIM, on a tax-equivalent basis, increased to 4.73% during the six months ended June 30, 2018 from 4.24% in the six months ended June 30, 2017, primarily as a result of our loan growth and controlling our cost of funds in an increasing rate environment.

(1) Average loans are gross, including non-accrual loans and overdrafts (before deduction of net fees and allowance for loan losses). Loan fees of $3.7 million and $1.5 million, accretion of $1.9 million and $0.8 million, nonaccrual interest collections of $0.3 million and $0.3 million and syndication fee income of $0.2 million and $0.1 million are included in interest income in the three months ended June 30, 2018 and 2017, respectively.

(2) Interest income includes the effects of the tax-equivalent adjustments to increase tax-exempt interest income to a tax-equivalent basis.

As discussed above, the $25.1 million increase in interest income on loans held for investment during the three months ended June 30, 2018 compared to the three months ended June 30, 2017 was the primary driver of the $20.8 million increase in net interest income. The increase in loan interest income on loans held for investment of $25.1million was driven by an increase in average loans held for investment of $1,346.4 million to $3.3 billion as of June 30, 2018, as compared to $1.9 billion as of June 30, 2017, which was largely attributable to our merger with the Clayton Banks and loan growth in our metropolitan markets. The increase in loan income was partially offset by an increase of $4.7 million in interest expense due to increases in rates and volume of interest-bearing deposits and to a lesser extent, FHLB advances.

Loan fees of $6.6 million and $3.4 million, accretion of $3.6 million and $2.0 million, nonaccrual interest collections of $0.6 million and $0.9 million, and syndication fee income of $0.3 million and $0.4 million are included in interest income in the six months ended June 30, 2018 and 2017, respectively.  

(2) Interest income includes the effects of the tax-equivalent adjustments to increase tax-exempt interest income to a tax-equivalent basis.

As discussed above, the $46.7 million increase in loans held for investment interest income during the six months ended June 30, 2018 compared to June 30, 2017 was the primary driver of the $38.6 million increase in net interest income. The increase in loan interest income was driven by an increase in average loans held for investment of $1,335.1 million, or 70.0%, to $3.2 billion as of June 30, 2018, as compared to $1.9 billion as of June 30, 2017, which was largely attributable to our merger with the Clayton Banks in addition to loan growth in our metropolitan markets. The increase in loan income was partially offset by an increase in interest expense of $8.5 million due to increases in rates and volume of interest-bearing deposits and to a lesser extent, FHLB advances.

Provision for loan losses

The provision for loan losses charged to operating expense is an amount which, in the judgment of management, is necessary to maintain the allowance for loan losses at a level that is believed to be adequate to meet the inherent risks of losses in our loan portfolio. Factors considered by management in determining the amount of the provision for loan losses include the internal risk rating of individual credits, historical and current trends in net charge-offs, trends in nonperforming loans, trends in past due loans, trends in the market values of underlying collateral securing loans and the current economic conditions in the markets in which we operate. The determination of the amount is complex and involves a high degree of judgment and subjectivity.

Three months ended June 30, 2018 compared to three months ended June 30, 2017    

Our provision for loan losses for the three months ended June 30, 2018 was $1.1 million as compared to a reversal of $0.9 million for the three months ended June 30, 2017, is primarily attributable to our loan growth. Additionally, this increase included $0.7 million of subsequent deterioration on PCI loans during the period.

Six months ended June 30, 2018 compared to six months ended June 30, 2017    

Our provision for loan losses for the six months ended June 30, 2018 was $1.4 million as compared to a reversal of $1.1 million in the same period in the previous year, is primarily attributable to our loan growth and a couple of large recoveries during the six months ended June 30, 2017. This increase in provision expense also included $0.7 million of subsequent deterioration on PCI loans during the six months ended June 30, 2018.

57

Noninterest income

Our noninterest income includes gains on sales of mortgage loans, fees on mortgage loan originations, loan servicing fees, hedging results, fees generated from deposit services, investment services and trust income, gains and losses on securities, other real estate owned and other assets and other miscellaneous noninterest income.

The following table sets forth the components of noninterest income for the periods indicated:

	Three Months Ended June 30,					Six Months Ended June 30,
(dollars in thousands)	2018			2017		2018			2017
Mortgage banking income	$	28,544		$	30,239	$	55,015		$	55,319
Service charges on deposit accounts		2,132			1,796		4,229			3,562

Other		1,345			582		2,718			1,213
Total noninterest income	$	35,763		$	35,657	$	69,038		$	66,744

Three months ended June 30, 2018 compared to three months ended June 30, 2017

Noninterest income was $35.8 million for the three months ended June 30, 2018, an increase of $0.1 million, or 0.3%, as compared to $35.7 million for the three months ended June 30, 2017. Noninterest income to average assets (excluding any gains or losses from sale of securities) was 3.0% in the three months ended June 30, 2018 as compared to 4.4% in the three months ended June 30, 2017.

Mortgage banking income primarily includes origination fees on mortgage loans including fees and realized gains and losses on the sale of mortgage loans, unrealized change in fair value of mortgage loans and derivatives, and mortgage servicing fees. Mortgage banking income is initially driven by the recognition of interest rate lock commitments (IRLCs) at fair value at inception of the IRLCs. This is subsequently adjusted for changes in the overall interest rate environment offset by derivative contracts entered into to offset the interest rate exposure. Upon the sale of the loan, the net fair value gain is reclassified to the realized gain on sale of loan. Mortgage banking income was $28.5 million and $30.2 million for the three months ended June 30, 2018 and 2017, respectively.

During the second quarter of 2018, the Bank’s mortgage operations had sales of $1,706.9 million which generated a sales margin of 1.58%. This compares to $1,535.3 million and a sales margin of 1.56% for the three months ended June 30, 2017. Mortgage banking income from gains on sale and related fair value changes amounted to $24.7 million during the three months ended June 30, 2018 compared to $29.3 million for the same period in the previous year. This activity was driven by an decrease in interest rate lock volume of $181.6million, or 8.4%, to $1,976.0 million for the three months ended June 30, 2018 due to slow down in the mortgage market, change in delivery channel mix, and overall compressing margins. Changes in market conditions have also shifted the mix of interest rate lock commitments by purpose to 71% purchase for the three months ended June 30, 2018 from 64% purchase for the same period in the prior year. Income from mortgage servicing was $5.6 million and $2.7 million for the three months ended June 30, 2018 and 2017, respectively, offset by a decline in fair value on MSRs and related hedging activity of $1.8 million and $1.8 million in the three months ended June 30, 2018 and 2017, respectively.

Mortgage banking income attributable to our Mortgage segment was $21.7 million and $23.1 million for the three months ended June 30, 2018 and 2017, respectively, and mortgage banking income attributable to our Banking segment was $6.9 million and $7.1 million for the three months ended June 30, 2018 and 2017, respectively.

Service charges on deposit accounts include analysis and maintenance fees on accounts, per item charges, non-sufficient funds and overdraft fees. Service charges on deposit accounts were $2.1 million and $1.8 million for the three months ended June 30, 2018 and 2017, respectively. The $0.3 millionincrease is due to our growth in deposits, including contributed deposits of the Clayton Banks.

ATM and interchange fees include debit card interchange, ATM and other consumer fees. These fees increased by $0.5million to $2.6 million during the three months ended June 30, 2018 from $2.1million for the three months ended June 30, 2017, also primarily due to the merger with the Clayton Banks.

Investment services and trust income for the three months ended June 30, 2018 was $1.2 million compared to $0.9 million for the three months ended June 30, 2017. This increase is primarily related to increased trust operations in connection with our merger with the Clayton Banks.

Loss on securities for the three months ended June 30, 2018 was $42 thousand compared to gains on securities for the three months ended June 30, 2017 of $29 thousand. Activity is typically driven by sales activity within our available-for-sale securities portfolio in addition to change in fair value of equity securities with readily determinable market values. Sales activity is attributable to management taking advantage of portfolio structuring opportunities to maintain comparable interest rates and maturities and to fund current loan growth in addition to overall asset liability management. The loss in the three months ended June 30, 2018 includes a $43 thousand charge for decline in fair value on equity securities offset by a $1 thousand gain on early call of available-for-sale debt securities. There were no sales of securities during the three months ended June 30, 2018 while there were $12.2 million of securities sold during the three months ended June 30, 2017.

Net gain on sales or write-downs of other real estate owned for the three months ended June 30, 2018 was $23 thousand compared to a net gain of $23 thousand for the three months ended June 30, 2017. This activity was the result of specific sales and valuation transactions of other real estate.

Other noninterest income for the three months ended June 30, 2018 increased to $1.3 million as compared to $0.6 million for the three months ended June 30, 2017, reflecting the contribution from the Clayton Banks.

Six months ended June 30, 2018 compared to six months ended June 30, 2017

Noninterest income was $69.0 million for the six months ended June 30, 2018, an increase of $2.3 million, or 3.4%, as compared to $66.7 million for the six months ended June 30, 2017. Noninterest income to average assets (excluding any

59

gains or losses from sale of securities) was 3.0% in the six months ended June 30, 2018 as compared to 4.2% in the six months ended June 30, 2017.

Mortgage banking income was relatively flat at $55.0 million and $55.3 million for the six months ended June 30, 2018 and 2017, respectively. Sales of mortgage loans totaled $3,389.7 million, generating a sales margin of 1.49% for the six months ended June 30, 2018 as compared to $3,026.5 million, generating a sales margin of 1.70% for the six months ended June 30, 2017.  This contributed to $48.1 million in mortgage banking income for the six months ended June 30, 2018 compared to $52.2 million for the six months ended June 30, 2017. The decrease in gain was due to different product mix and compressing margins due to competitive pressures in the mortgage marketplace. This activity was driven by an increase in interest rate lock commitment volume of $349.2 million, or 9.3%, to $4,105.0 million for the six months ended June 30, 2018 from the six months ended June 30, 2017. While interest rate lock volume increased year over year, the change in mix by delivery channel and overall compressing margins result in relatively flat income from origination and sales activity. Income from mortgage servicing was $10.4 million for the six months ended June 30, 2018 compared with $5.5 million for the same period in 2017. This income was partially offset by a $3.4 million charge during the six months ended June 30, 2018 related to changes in fair value of MSRs and related hedges compared to a $2.3 million charge for the same period in the previous year.

The components of mortgage banking income for the six months ended June 30, 2018 and 2017 were as follows:

Noninterest expense

Our noninterest expense includes salaries and employee benefits expense, occupancy expense, legal and professional fees, data processing expense, regulatory fees and deposit insurance assessments, advertising and promotion and other real estate owned expense, among others. We monitor the ratio of noninterest expense to the sum of net interest income plus noninterest income, which is commonly known as the efficiency ratio.

The following table sets forth the components of noninterest expense for the periods indicated:

	Three Months Ended June 30,				Six Months Ended June 30,

Three months ended June 30, 2018 compared to three months ended June 30, 2017

Noninterest expense increased by $7.2 million during the three months ended June 30, 2018 to $56.4 million as compared to $49.1 million in the three months ended June 30, 2017. This increase resulted primarily from the $3.7 million increase in salary and employee benefits combined with overall increases associated with our growth and merger with the Clayton Banks.

Salaries and employee benefits expense is the largest component of noninterest expenses representing 61.2% and 62.6% of total noninterest expense in the three months ended June 30, 2018 and 2017, respectively. During the three months ended June 30, 2018, salaries and employee benefits expense increased $3.7 million, or 12.1%, to $34.5 million as compared to $30.8 million for the three months ended June 30, 2017. The increase in the three months ended June 30, 2018 was primarily due to increased costs associated with our growth, including our merger with the Clayton Banks. The Company headcount increased 2.5% to 1,421 employees at June 30, 2018 from 1,386 employees at December 31, 2017 and 1,147 employees at June 30, 2017. Additionally, the Company expects to hire twelve to fifteen revenue producers during the last half of 2018, which will likely increase expenses related to salaries and benefits throughout the remainder of the year.

Salaries and employee benefits also reflects $1.9 million and $1.8 million accrued for equity compensation grants during the three months ended June 30, 2018 and 2017, respectively. These grants comprise restricted stock units that were granted in conjunction with the 2016 IPO to all full-time associates and extended to new associates and retained former Clayton employees at the end of 2017 in addition to accrual of annual stock-based performance grants.

Occupancy and equipment expense in the three months ended June 30, 2018 was $3.7 million, up slightly compared to $3.3 million for the three months ended June 30, 2017, reflecting the impact of the Clayton Banks.

Legal and professional fees increased slightly to $2.0 million for the three months ended June 30, 2018 as compared to $1.0 million for the three months ended June 30, 2017. The increase in legal and professional fees is attributable to our growth and volume of business.

61

Data processing costs increased $0.7 million to $2.1 million for the three months ended June 30, 2018 from $1.5 million for thethree months ended June 30, 2017.

Merger and conversion expenses of $0.8 million for the three months ended June 30, 2017 was related to the merger with the Clayton Banks, which closed on July 31, 2017. There were such expenses for the three months ended June 30, 2018.

Amortization of core deposits and other intangibles totaled $0.8 million for the three months ended June 30, 2018 compared to $0.1 million for the three months ended June 30, 2017. The increase is due to the additional core deposit intangible and other intangibles recognized in our merger with the Clayton Banks.

Regulatory fees and deposit insurance assessments increased slightly to $0.7 million from $0.5 for the three months ended June 30, 2018 and 2017.

During the three months ended June 30, 2017, the Company sold $11,935 of mortgage servicing rights on $1,085,405 of serviced mortgage loans and recognized a loss of $0.03 million in connection with this transaction. There was no such sale during the three months ended June 30, 2018. During the second quarter of 2018, the Company entered into a letter of intent for the sale of certain mortgage servicing rights on $3,217.6 million of serviced mortgage loans, of which the Company will continue to subservice until they can be transferred to the purchaser. The transaction is expected to close during the third quarter of 2018 and the Company does not expect there to be a significant gain or loss related to this transaction.

Other real estate owned expense was $0.6 million and $0.2 million for the three months ended June 30, 2018 and 2017. Sales of other real estate owned amounting to $0.8 million and $0.7 million was the primary driver for the expense during the three months ended June 30, 2018 and 2017, respectively.

Other noninterest expense for three months ended June 30, 2018 was $8.1 million, an increase of $1.1 million from the three months ended June 30, 2017. This increase includes $0.7 million in expenses related to the completion of a $151.8 million follow-on secondary offering during the three months ended June 30, 2018 and reflects our growth, including the impact of the merger with the Clayton Banks.

Six months ended June 30, 2018 compared to six months ended June 30, 2017

Occupancy and fixed asset expense in the six months ended June 30, 2018 increased $0.9 million to $7.3 million from $6.4 million for the six months ended June 30, 2017 as a result of our merger with the Clayton Banks and expansion of our footprint.

Legal and professional fees were $4.0 million for the six months ended June 30, 2018 as compared to $2.5 million for the six months ended June 30, 2017. The increase in legal and professional fees is attributable to additional professional services related to our growth and volume of business.

Efficiency ratio

The efficiency ratio is one measure of productivity in the banking industry. This ratio is calculated to measure the cost of generating one dollar of revenue. That is, the ratio is designed to reflect the percentage of one dollar which must be expended to generate that dollar of revenue. We calculate this ratio by dividing noninterest expense by the sum of net interest income and noninterest income.  For an adjusted efficiency ratio, we exclude certain gains, losses and expenses we do not consider core to our business.

Our efficiency ratio was 64.6% and 74.4% for the three months ended June 30, 2018 and 2017, respectively, and 66.6% and 75.0% for the six months ended June 30, 2018 and 2017, respectively. Our adjusted efficiently ratio, on a tax-equivalent basis, was 62.1% and 70.2% for the three months ended June 30, 2018 and 2017, respectively, and 63.7% and 71.7% for the six months ended June 30, 2018 and 2017, respectively. See “GAAP reconciliation and management explanation of non-GAAP financial measures” for a discussion of the adjusted efficiency ratio.

This reflects the federal rate change enacted by the Tax Reform Act on December 22, 2017. As such, our effective tax rates were 26.10% and 36.91% for the three months ended June 30, 2018 and 2017, respectively, and 24.1% and 36.37% for the six months ended June 30, 2018 and 2017, respectively. The primary differences from the enacted rates are applicable state income

taxes reduced for non-taxable income and additional deductions for equity-based compensation upon the distribution of RSUs and nondeductible stock offering costs.

Financial condition

The following discussion of our financial condition compares the six months ended June 30, 2018 with the year ended December 31, 2017.

Total assets

Our total assets were $4.92 billion at June 30, 2018, an increase of $195.5 million from total assets of $4.73 billion at December 31, 2017. This increase was largely attributable an increase of $248.7 million in loans held for investment, driven by strong demand for our loan products in our markets and the success of our growth initiatives. This growth was partially offset by a $151.3 million decrease in loans held for sale, reflecting the decline in the mortgage market and derecognition of rebooked GNMA delinquent loans, which made up $43.0 million of total loans held for sale as of December 31, 2017.

Loan portfolio

Our loan portfolio is our most significant earning asset, comprising 69.4% and 67.0% of our total assets as of June 30, 2018 and December 31, 2017, respectively. Our strategy is to grow our loan portfolio by originating quality commercial and consumer loans that comply with our credit policies and that produce revenues consistent with our financial objectives. Our overall lending approach is primarily focused on providing credit to our customers directly rather than purchasing loan syndications and loan participations from other banks (collectively, “Participated loans”).  At June 30, 2018 and December 31, 2017, loans held for investment included approximately $93.9million and $62.9million, respectively, related to Participated loans.  Currently, our loan portfolio is diversified relative to industry concentrations across the various loan portfolio categories.  At June 30, 2018 and December 31, 2017, our outstanding loans to the broader healthcare industry made up less than 5% of our total outstanding loans and are spread across nursing homes, assisted living facilities, outpatient mental health and substance abuse centers, home health care services, and medical practices within our geographic markets. We believe our loan portfolio is well-balanced, which provides us with the opportunity to grow while monitoring our loan concentrations.

Loans

Loans increased $248.7 million, or 7.9%, to $3.42 billion as of June 30, 2018 as compared to $3.17 billion as of December 31, 2017. Our loan growth during the six months ended June 30, 2018 has been comprised of increases of $98.0 million, or 13.7%, in commercial and industrial, $74.1 million, or 16.5%, in construction loans, $49.0 million, or 8.9%, in non-owner occupied commercial real estate and $55.8 million, or 7.6%, in residential real estate partially offset by a decrease of  $25.0 million, or 5.0%, in owner occupied commercial real estate and $3.3 million, or 1.5%, in consumer and other, respectively. The increase in loans during the six months ended June 30, 2018 is attributable to continued strong demand in our metropolitan markets, building customer relationships and continued favorable economic conditions throughout much of our geographic footprint.

Loan concentrations are considered to exist when there are amounts loaned to a number of borrowers engaged in similar activities which would cause them to be similarly impacted by economic or other conditions. At June 30, 2018 and December 31, 2017, there were no concentrations of loans exceeding 10% of loans other than the categories of loans disclosed in the table above.

Banking regulators have established thresholds of less than 100% for concentrations in construction lending and less than 300% for concentrations in commercial real estate lending that management monitors as part of the risk management process. The construction concentration ratio is a percentage of the outstanding construction and land development loans to total risk-based capital. The commercial real estate concentration ratio is a percentage of the outstanding balance of non-owner occupied commercial real estate, multifamily, and construction and land development loans to total risk-based capital. Management strives to operate within the thresholds set forth above. When a company’s ratios are in excess of one or both of these guidelines, banking regulators generally require an increased level of monitoring in these lending areas by management. The table below shows concentration ratios for the Bank and Company as of June 30, 2018 and December 31, 2017. At June 30, 2018, FirstBank slightly exceeded the 100% guideline; however, we remain committed to operating within the applicable guidance thresholds over the longer-term.

Loan categories

The principal categories of our loan held for investment portfolio are discussed below:

Commercial and industrial loans. We provide a mix of variable and fixed rate commercial and industrial loans. Our commercial and industrial loans are typically made to small and medium-sized manufacturing, wholesale, retail and service businesses for working capital and operating needs and business expansions, including the purchase of capital equipment and loans made to farmers relating to their operations. This category also includes loans secured by manufactured housing receivables. Commercial and industrial loans generally include lines of credit and loans with maturities of five years or less. The loans are generally made with operating cash flows as the primary source of repayment, but may also include collateralization by inventory, accounts receivable, equipment and personal guarantees. We plan to continue to make commercial and industrial loans an area of emphasis in our lending operations in the future. As of June 30, 2018, our commercial and industrial loans comprised of $813.1 million, or 24% of loans, compared to $715.1 million, or 23%, of loans as of December 31, 2017.

65

Commercial real estate owner-occupied loans.    Our commercial real estate owner-occupied loans include loans to finance commercial real estate owner occupied properties for various purposes including use as offices, warehouses, production facilities, health care facilities, retail centers, restaurants, churches and agricultural based facilities. Commercial real estate owner-occupied loans are typically repaid through the ongoing business operations of the borrower, and hence are dependent on the success of the underlying business for repayment and are more exposed to general economic conditions. As of June 30, 2018, our owner occupied commercial real estate loans comprised $470.9 million, or 14% of loans, compared to $495.9 million, or 16%, of loans as of December 31, 2017.

Commercial real estate non-owner occupied loans.    Our commercial real estate non-owner occupied loans include loans to finance commercial real estate non-owner occupied investment properties for various purposes including use as offices, warehouses, health care facilities, hotels, mixed-use residential/commercial, manufactured housing communities, retail centers, assisted living facilities and agricultural based facilities. Commercial real estate non-owner occupied loans are typically repaid with the funds received from the sale of the completed property or rental proceeds from such property, and are therefore more sensitive to adverse conditions in the real estate market, which can also be affected by general economic conditions. As of June 30, 2018, our non-owner occupied commercial real estate loans comprised $600.6 million, or 18% of loans, compared to $551.6 million, or 17%, of loans as of December 31, 2017.

Residential real estate 1-4 family mortgage loans.    Our residential real estate 1-4 family mortgage loans are primarily made with respect to and secured by single family homes, including manufactured homes with real estate, which are both owner-occupied and investor owned. We intend to continue to make residential 1-4 family housing loans at a similar pace, so long as housing values in our markets do not deteriorate from current prevailing levels and we are able to make such loans consistent with our current credit and underwriting standards. First lien residential 1-4 family mortgages may be affected by unemployment or underemployment and deteriorating market values of real estate. As of June 30, 2018, our residential real estate mortgage loans comprised $528.2 million, or 15% of loans, compared to $481.0 million, or 15%, of loans as of December 31, 2017.

Residential line of credit loans.    Our residential line of credit loans are primarily revolving, open-end lines of credit secured by 1-4 family residential properties. We intend to continue to make residential line of credit loans if housing values in our markets do not deteriorate from current prevailing levels and we are able to make such loans consistent with our current credit and underwriting standards. Residential line of credit loans may be affected by unemployment or underemployment and deteriorating market values of real estate. Our home equity loans as of June 30, 2018 comprised $208.7 million, or 6% of loans, compared to $195.0 million, or 6%, of loans as of December 31, 2017.

Multi-family residential loans.    Our multi-family residential loans are primarily secured by multi-family properties, such as apartments and condominium buildings. These loans may be affected by unemployment or underemployment and deteriorating market values of real estate. Our multifamily loans as of June 30, 2018, comprised $57.3 million, or 2% of loans, compared to $62.4 million, or 2%, of loans as of December 31, 2017.

Construction loans.    Our construction loans include commercial construction, land acquisition and land development loans and single-family interim construction loans to small- and medium-sized businesses and individuals. These loans are generally secured by the land or the real property being built and are made based on our assessment of the value of the property on an as-completed basis. We expect to continue to make construction loans at a similar pace so long as demand continues and the market for and values of such properties remain stable or continue to improve in our markets subject to regulatory guidance thresholds. These loans can carry risk of repayment when projects incur cost overruns, have an increase in the price of building materials, encounter zoning and environmental issues, or encounter other factors that may affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively impacted when the market experiences a deterioration in the value of real estate. As of June 30, 2018, our construction loans comprised $522.5 million, or 15% of loans, compared to $448.3 million, or 14%, of loans as of December 31, 2017. 

Consumer and other loans.    Consumer and other loans include consumer loans made to individuals for personal, family and household purposes, including car, boat and other recreational vehicle loans, manufactured homes without real estate and personal lines of credit. Consumer loans are generally secured by vehicles, manufactured homes, or other household goods. The collateral securing consumer loans may depreciate over time. The Company seeks to minimize these risks through its underwriting standards. Other loans also include loans to states and political subdivisions in the U.S. These loans are generally subject to the risk that the borrowing municipality or political subdivision may lose a significant portion of its tax base or that the project for which the loan was made may produce inadequate revenue. None of these categories of loans represents a significant portion of our loan portfolio. As of June 30, 2018, our consumer and other loans comprised $214.4 million, or 6% of loans, compared to $217.7 million, or 7%, of loans as of December 31, 2017.

Loan maturity and sensitivities

The following tables present the contractual maturities of our loan portfolio as of June 30, 2018 and December 31, 2017. Loans with scheduled maturities are reported in the maturity category in which the payment is due. Demand loans with no stated maturity and overdrafts are reported in the “due in 1 year or less” category. Loans that have adjustable rates are shown as amortizing to final maturity rather than when the interest rates are next subject to change. The tables do not include prepayment or scheduled repayments.

Asset quality

In order to operate with a sound risk profile, we focus on originating loans that we believe to be of high quality. We have established loan approval policies and procedures to assist us in maintaining the overall quality of our loan portfolio. When delinquencies in our loans exist, we rigorously monitor the levels of such delinquencies for any negative or adverse trends. From time to time, we may modify loans to extend the term or make other concessions, including extensions or interest rate modifications, to help a borrower with a deteriorating financial condition stay current on their loan and to avoid foreclosure. Furthermore, we are committed to collecting on all of our loans which can result in us carrying higher nonperforming assets. We believe this practice leads to higher recoveries in the long term.

Nonperforming assets

Our nonperforming assets consist of nonperforming loans, other real estate owned and other miscellaneous non-earning assets. Nonperforming loans are those on which the accrual of interest has stopped, as well as loans that are contractually 90 days past due on which interest continues to accrue. Generally, the accrual of interest is discontinued when the full collection of principal or interest is in doubt or when the payment of principal or interest has been contractually 90 days past due, unless the obligation is both well secured and in the process of collection. In our loan review process, we seek to identify and proactively address nonperforming loans.

Purchased credit impaired (“PCI”) loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement remains unpaid after the due date of the scheduled payment. However, these loans are considered as performing, even though they may be contractually past due, as any non-payment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or future period yield adjustments. The accrual of interest is discontinued on PCI loans if management can no longer reliably estimate future cash flows on the loan. No PCI loans were classified as nonaccrual at June 30, 2018 or December 31, 2017 as the carrying value of the respective loan or pool of loans cash flows were considered estimable and probable of collection. Therefore, interest revenue, through accretion of the difference between the carrying value of the loans and the expected cash flows, is being recognized on all PCI loans.

As of June 30, 2018 and December 31, 2017, we had $25.8 million and $72.3 million, respectively, in nonperforming assets. As of June 30, 2018 and December 31, 2017, other real estate owned included $5.4 million and $5.9 million, respectively, of excess land and facilities resulting from the merger with the Clayton Banks that is held for sale. Other nonperforming assets as of June 30, 2018 and December 31, 2017 also included $0.6 million and $0.7 million, respectively, of restricted marketable equity securities received in satisfaction of a previously charged-off loan and $1.8 million and $1.7 million, respectively, in other repossessed assets.

As of December 31, 2017, the amount of loans held for sale that are 90 days or more past due includes government guaranteed GNMA mortgage loans that the Bank, as the original transferor and servicer, has the right, but not obligation, to repurchase totaling $43.0 million at December 31, 2017 with an offsetting liability in the same amount. This option was not exercised and the rebooked GNMA loans were derecognized in 2018. At June 30, 2018, there were $52.2 million of delinquent GNMA loans that had previously been sold; however, we determined there not to be a more-than-trivial benefit of rebooking based on an analysis of interest rates and an assessment of potential reputational risk associated with these loans. As such, we did not rebook the delinquent GNMA loans as of June 30, 2018; however, we continue to assess quarterly going forward.

If our nonperforming assets would have been current during the three and six months ended June 30, 2018, we would have recorded additional income of $0.1 million and $0.3 million, respectively, and $0.1 million and $0.3 million for the three and six months ended June 30, 2017, respectively. We had net interest recoveries of $0.3 million and $0.6 million for the three and six months ended June 30, 2018, respectively, recognized on loans that had previously been charged off or classified as nonperforming in previous periods. This compares to $0.6 million and $0.9 million for the three and six months ended June 30, 2017, respectively.

(1) Amount for December 31, 2017 includes $43.0 million in rebooked GNMA loans for which there is no obligation to repurchase. See the previous discussion of serviced GNMA loans eligible for repurchase and the impact of our repurchases of delinquent mortgage loans under the GNMA optional repurchase program (see Note 1 to the unaudited Consolidated Financial Statements).

Total nonperforming loans as a percentage of total loans were 0.26% as of June 30, 2018 as compared to 0.32% as of December 31, 2017. Our coverage ratio, or our allowance for loan losses as a percentage of our nonperforming loans, was 299.0% as of June 30, 2018 as compared to 238.1% as of December 31, 2017.

Management has evaluated the aforementioned loans and other loans classified as nonperforming and believes that all nonperforming loans have been adequately reserved for in the allowance for loan losses at June 30, 2018. Management also continually monitors past due loans for potential credit quality deterioration. Loans 30-89 days past due were $11.0 million at June 30, 2018, as compared to $15.1 million for the year ended December 31, 2017.

Under acquisition accounting rules, acquired loans were recorded at their estimated fair value. We recorded the loan portfolio acquired from the Clayton Banks at fair value as of the July 31, 2017 acquisition date, which resulted in a discount to the loan portfolio’s previous carrying value. Neither the credit portion nor any other portion of the fair value mark is reflected in the reported allowance for loan and lease losses; however, as of June 30, 2018, the allowance included $0.7 million in reserves related to subsequent deterioration since the acquisition date.

Other real estate owned consists of properties acquired through foreclosure or acceptance of a deed in lieu of foreclosure in addition to excess facilities held for sale. These properties are carried at the lower of cost or fair market value based on appraised value less estimated selling costs. Losses arising at the time of foreclosure of properties are charged against the allowance for loan losses. Reductions in the carrying value subsequent to acquisition are charged to earnings and are included in “Gain/(loss) on sales or write-downs of other real estate owned” in the accompanying consolidated statements of income. During the three and six months ended June 30, 2018, other real estate owned with a cost basis of $0.8 million and $2.2 million, respectively, was sold resulting in a net gain of $23 thousand and net loss of $0.2 million, respectively. For the same periods in the previous year, other real estate owned with a cost basis of $0.7 million and $2.9 million, respectively, was sold resulting in a net gain of $23 thousand and $0.8 million, respectively.

Classified loans

Accounting standards require us to identify loans, where full repayment of principal and interest is doubtful, as impaired loans. These standards require that impaired loans be valued at the present value of expected future cash flows, discounted at the loan’s effective interest rate, or using one of the following methods: the observable market price of the loan or the fair value of the underlying collateral if the loan is collateral dependent. We have implemented these standards in our quarterly review of the adequacy of the allowance for loan losses and identify and value impaired loans in accordance with guidance on these standards. As part of the review process, we also identify loans classified as watch, which have a potential weakness that deserves management’s close attention.

Loans totaling $58.5 million and $55.5 million were classified as substandard under our policy at June 30, 2018 and December 31, 2017, respectively. As of June 30, 2018 and December 31, 2017, $27.6 million and $32.0million of substandard loans were acquired with deteriorated credit quality in connection with our mergers and acquisitions. The following table sets forth information related to the credit quality of our loan portfolio at June 30, 2018 and December 31, 2017.

Allowance for loan losses

The allowance for loan losses is the amount that, based on our judgment, is required to absorb probable credit losses inherent in our loan portfolio and that, in management’s judgment, is appropriate under GAAP. The determination of the amount of the allowance is complex and involves a high degree of judgment and subjectivity. Among the material estimates required to establish the allowance are loss exposure at default, the amount and timing of future cash flows on impacted loans, value of collateral and determination of the loss factors to be applied to the various elements of the portfolio.

Our methodology for assessing the adequacy of the allowance for loan losses includes a general allowance for performing loans, which are grouped based on similar characteristics, and an allocated allowance for individual impaired loans. Actual credit losses or recoveries are charged or credited directly to the allowance.

The appropriate level of the allowance is established on a quarterly basis after input from management and our loan review staff and is based on an ongoing analysis of the credit risk of our loan portfolio. In making our evaluation of the credit risk of the loan portfolio, we consider factors such as the volume, growth and composition of our loan portfolio, the diversification by industry of our commercial loan portfolio, the effect of changes in the local real estate market on collateral values, trends in past dues, our experience as a lender, changes in lending policies, the effects on our loan portfolio of current economic indicators and their probable impact on borrowers, historical loan loss experience, industry loan loss experience, the amount of nonperforming loans and related collateral and the evaluation of our loan portfolio by our loan review function.

In addition, on a regular basis, management and the Company’s Board of Directors review loan ratios. These ratios include the allowance for loan losses as a percentage of loans, net charge-offs as a percentage of average loans, the provision for loan losses as a percentage of average loans, nonperforming loans as a percentage of loans and the allowance coverage on nonperforming loans. Also, management reviews past due ratios by relationship manager, individual markets and the Bank as a whole. The allowance for loan losses was $26.3 million and $24.0 million at June 30, 2018 and December 31, 2017, respectively.

Mortgage loans held for sale

Mortgage loans held for sale were $374.9 million at June 30, 2018 compared to $526.2 million at December 31, 2017. Interest rate lock volume for the three months ended June 30, 2018 and 2017 totaled $1,976.0 million and $2,157.6 million, respectively, and amounted to $4,105.0 million and $3,755.8 million for the six months ended June 30, 2018 and 2017, respectively. Generally, mortgage volume increases in lower interest rate environments and robust housing markets and decreases in rising interest rate environments and slower housing markets. Rising interest rates during the three months ended June 30, 2018 resulted in slow down of interest rate lock volume which is expected to persist through the remainder of 2018. Interest rate lock commitments in the pipeline at June 30, 2018 and December 31, 2017 were $597.6 million and $054.2 million, respectively.

Mortgage loans to be sold are sold either on a “best efforts” basis or under a mandatory delivery sales agreement. Under a “best efforts” sales agreement, residential real estate originations are locked in at a contractual rate with third party private investors or directly with government sponsored agencies, and we are obligated to sell the mortgages to such investors only if the mortgages are closed and funded. The risk we assume is conditioned upon loan underwriting and market conditions in the national mortgage market. Under a mandatory delivery sales agreement, we commit to deliver a certain principal amount of mortgage loans to an investor at a specified price and delivery date. Penalties are paid to the investor if we fail to satisfy the contract. Gains and losses are realized at the time consideration is received and all other criteria for sales treatment have been met. These loans are typically sold within thirty days after the loan is funded. Although loan fees and some interest income are derived from mortgage loans held for sale, the primary source of income is gains from the sale of these loans in the secondary market.

Deposits

Deposits represent the Bank’s primary source of funds. We continue to focus on growing core deposits through our relationship driven banking philosophy, community-focused marketing programs, and initiatives such as the development of our treasury management services.

Total deposits were $3.91 billion and $3.66 billion as of June 30, 2018 and December 31, 2017, respectively. Noninterest-bearing deposits at June 30, 2018 and December 31, 2017 were $970.9 million and $888.2 million, respectively, while interest-bearing deposits were $2,939.0 million and $2,776.2 million at June 30, 2018 and December 31, 2017, respectively. The 6.7% increase in total deposits is mainly attributable to continued focus on deposit growth, seasonal growth in public deposits, and other movements in customer activity including increases from certain large depositors.

Interest-bearing deposits acquired from our merger with the Clayton Banks included brokered and internet time deposits amounting to $85.7 million as of December 31, 2017. These brokered and internet time deposits declined to $65.9 million as of June 30, 2018 and are expected to continue to run-off.

Included in noninterest-bearing deposits are certain mortgage escrow deposits that our third party servicing provider, Cenlar, transfers to the Bank which totaled $88.4 million and $53.7 million at June 30, 2018 and December 31, 2017, respectively. This balance is expected to decrease in the third quarter of 2018 upon the closing of the pending sale of mortgage servicing rights.  See Note 6, “Mortgage Servicing Rights” in these Notes to the consolidated unaudited financial statements for further details regarding this sale.

Additionally, our deposits from municipal and governmental entities (i.e., “public deposits”) totaled $408.7 million at June 30, 2018 compared to $368.5 million at December 31, 2017, which is typical of the seasonal growth from revenue collections and will gradually decline over the remainder of the calendar year.

In connection with the merger of the Clayton Banks, a significant amount of the $184.2 million cash portion of the purchase price together with pre-acquisition dividends were deposited in interest bearing accounts with our Bank.  Since that time, as expected, these deposits balances have declined and should continue to decline over the remainder of 2018 and 2019.

Our deposit base also includes certain commercial and high net worth individuals that periodically place deposits with the Bank for short periods of time and can from period to period cause fluctuations in the overall level of customer deposits outstanding. These fluctuations may include certain deposits from related parties as disclosed in Note 14 to the consolidated unaudited financial statements included in this Form 10-Q. The mix between noninterest bearing and interest bearing as of June 30, 2018 remained consistent with the mix at December 31, 2017; however, management continues to focus on strategic pricing to grow noninterest bearing deposits while allowing more costly funding sources, including certain brokered and internet time deposits, to mature.

Average deposit balances by type, together with the average rates per periods are reflected in the average balance sheet amounts, interest earned and yield analysis tables included above under the discussion of net interest income.

Borrowed funds

Deposits and investment securities available for sale are the primary source of funds for our lending activities and general business purposes. However, we may also obtain advances from the FHLB, purchase federal funds and engage in overnight borrowing from the Federal Reserve, correspondent banks, or enter into client purchase agreements. We also use these sources of funds as part of our asset liability management process to control our long-term interest rate risk exposure, even if it may increase our short-term cost of funds. This may include match funding of fixed-rate loans. Our level of short-term borrowing can fluctuate on a daily basis depending on funding needs and the source of funds to satisfy the needs.

Total borrowings include securities sold under agreements to repurchase, lines of credit, advances from the FHLB, federal funds, junior subordinated debentures and related party subordinated debt.

(1) Includes $100.0 million of FHLB advances with 90 day fixed rate repricing terms used in the funding strategy of the merger with the Clayton Banks.  Given their functional purpose of securing longer-term funding and the intention to utilize them in a longer-term capacity, management categorizes these FHLB advances as long-term debt on our consolidated balance sheets.

Short-term borrowings

The following table summarizes short-term borrowings (borrowings with maturities of one year or less), which consist of federal funds purchased from our correspondent banks on an overnight basis at the prevailing overnight market rates, securities sold under agreements to repurchase and FHLB Cash Management variable rate advances, or CMAs, and the weighted average interest rates paid:

	Three months ended			Six months ended			Year ended

Lines of credit and other borrowings

As a member of the FHLB Cincinnati, the Bank receives advances from the FHLB pursuant to the terms of various agreements that assist in funding its mortgage and loan portfolio balance sheet. Under the agreements, we pledge qualifying residential mortgages of $598.7 million and $761.2 million and qualifying commercial mortgages of $539.6 million and $207.4 million as collateral securing a line of credit with a total borrowing capacity of $700.0 million and $671.5 million as of June 30, 2018 and December 31, 2017, respectively.

Borrowings against the line were $8.4million and $12.4million in long term advances and $185.0 million and $190.0 million in overnight CMAs as of June 30, 2018 and December 31, 2017, respectively. In the third quarter of 2017, we borrowed $100.0 million in variable rate advances as part of the funding strategy for the Clayton Banks merger. The advances have 90 day fixed rate repricing terms. Given their functional purpose of securing longer-term funding and our intention and ability to utilize them in a longer-term capacity, we categorize these FHLB advances as long-term debt on the consolidated balance sheets. An additional line of $300 million has been secured with the FHLB for overnight borrowing; however, additional collateral may be needed to draw on the line. Subsequent to June 30, 2018, the line was

78

increased to $800.0 million.  See Note 1. “Basis of presentation” in the notes to the consolidated unaudited financial statements for further details regarding the line increase.

Additionally, the Bank maintained a line with the Federal Reserve Bank through the Borrower-in-Custody program. As of June 30, 2018 and December 31, 2017, $1,218.5 million and $724.3 million of qualifying loans and $12.8 million and $13.5 million of investment securities were pledged to the Federal Reserve Bank, securing a line of credit of $849.3 million and $529.5 million.

The Bank also maintains lines with certain correspondent banks that provide borrowing capacity in the form of federal fund purchases in the aggregate amount of $240.0 million as of June 30, 2018 and $165.0 million as of December 31, 2017. Borrowings against the lines were $2.5 million and $0 as of June 30, 2018 and December 31, 2017, respectively.

We have two wholly owned subsidiaries that are statutory business trusts (“Trusts”). The Trusts were created for the sole purpose of issuing 30-year capital trust preferred securities to fund the purchase of junior subordinated debentures issued by the Company. As of June 30, 2018 and December 31, 2017, our $0.9 million investment in the Trusts was included in other assets in the accompanying consolidated balance sheets, and our $30.0 million obligation is reflected as junior subordinated debt, respectively. The junior subordinated debt bears interest at floating interest rates based on a spread over 3-month LIBOR plus 315 basis points (5.49% and 4.82% at June 30, 2018 and December 31, 2017, respectively) for the $21.7 million debenture and 3-month LIBOR plus 325 basis points (5.56% and 4.59% at June 30, 2018 and December 31, 2017, respectively) for the remaining $9.3 million. The $9.3 million debenture may be redeemed prior to the 2033 maturity date upon the occurrence of a special event, and the $21.7 million debenture may be redeemed prior to 2033 at our option.

Liquidity and capital resources

Bank liquidity management

We are expected to maintain adequate liquidity at the Bank to meet the cash flow requirements of clients who may be either depositors wishing to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. Our asset and liability management policy is intended to cause the Bank to maintain adequate liquidity and, therefore, enhance our ability to raise funds to support asset growth, meet deposit withdrawals and lending needs, maintain reserve requirements and otherwise sustain our operations. We accomplish this through management of the maturities of our interest-earning assets and interest-bearing liabilities. We believe that our present position is adequate to meet our current and future liquidity needs.

We continuously monitor our liquidity position to ensure that assets and liabilities are managed in a manner that will meet all of our short-term and long-term cash requirements. We manage our liquidity position to meet the daily cash flow needs of clients, while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of our shareholders. We also monitor our liquidity requirements in light of interest rate trends, changes in the economy and the scheduled maturity and interest rate sensitivity of the investment and loan portfolios and deposits.

As part of our liquidity management strategy, we are also focused on minimizing our costs of liquidity and attempt to decrease these costs by growing our noninterest bearing and other low-cost deposits. While we do not control the types of deposit instruments our clients choose, we do influence those choices with the rates and the deposit specials we offer. As a result of these strategies, we have been able to maintain a relatively low cost of funds in an increasing rate environment.

Our investment portfolio is another alternative for meeting liquidity needs. These assets generally have readily available markets that offer conversions to cash as needed. Securities within our investment portfolio are also used to secure certain deposit types and short-term borrowings. At June 30, 2018 and December 31, 2017, securities with a carrying value of $433.8 million and $337.6 million, respectively, were pledged to secure government, public, trust and other deposits and as collateral for short-term borrowings, letters of credit and derivative instruments.

Additional sources of liquidity include federal funds purchased and lines of credit. Interest is charged at the prevailing market rate on federal funds purchased and FHLB advances. Funds and advances obtained from the FHLB are used primarily to match-fund fixed rate loans in order to minimize interest rate risk and also used to meet day to day liquidity needs, particularly when the cost of such borrowing compares favorably to the rates that we would be required to pay to attract deposits. The balance of outstanding overnight CMAs at June 30, 2018 and December 31, 2017 were $185.0 million and $190.0 million, respectively. During the third quarter of 2017, $100.0 million of 90 day fixed-rate advances were borrowed as part of the funding strategy of merger with the Clayton Banks as described in management’s discussion and analysis on lines of credit and other borrowings. Given their functional purpose of securing longer-term funding and our intention to utilize them in a longer-term capacity, we categorize these FHLB advances as long-term debt on our consolidated balance sheets. At June 30, 2018 and December 31, 2017, the balance of our outstanding additional long-term advances with the FHLB were $8.4 million and $12.4  million, respectively. The remaining balance available with the FHLB was $406.5 million and $369.1 million at June 30, 2018 and December 31, 2017. We also maintain lines of credit

79

with other commercial banks in the form of fed funds purchased totaling $240.0 million and $165.0 million June 30, 2018 and December 31, 2017. These are unsecured, uncommitted lines of credit typically maturing at various times within the next twelve months. Borrowings against the lines were $2.5 million and $0 as of June 30, 2018 and December 31, 2017, respectively.

See discussion of deposit composition and seasonality in management’s discussion and analysis of deposits.

Holding company liquidity management

The Company is a corporation separate and apart from the Bank and, therefore, it must provide for its own liquidity. The Company’s main source of funding is dividends declared and paid to it by the Bank. Statutory and regulatory limitations exist that affect the ability of the Bank to pay dividends to the Company. Management believes that these limitations will not impact the Company’s ability to meet its ongoing short-term cash obligations. For additional information regarding dividend restrictions, see “Item 1. Business — Supervision and regulation,” “Item 1A. Risk Factors — Risks related to our business,” and “Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities — Dividend Policy,” each of which is set forth in our Annual Report.

Due to state banking laws, the Bank may not declare dividends in any calendar year in an amount exceeding the total of its net income for that year combined with its retained net income of the preceding two years, without the prior approval of the Tennessee Department of Financial Institutions (“TDFI”). Based upon this regulation, as of June 30, 2018 and December 31, 2017, $82.0 million and $105.5 million of the Bank’s retained earnings were available for the payment of dividends without such prior approval. In addition, dividends paid by the Bank to the Company would be prohibited if the effect thereof would cause the Bank’s capital to be reduced below applicable minimum capital requirements.

In the second quarter of 2018, the Company declared the initiation of a regular quarterly dividend of $0.06 per share, or $1.9 million. Subsequent to June 30, 2018, the Company declared its third quarter dividend in the same amount payable to stockholders of record as of July 31, 2018 on August 15, 2018.

The Company had cash balances on deposit totaling $22.4 million and $25.8 million at June 30, 2018 and December 31, 2017, respectively, for ongoing corporate needs.

The Company is party to a registration rights agreement with its former majority shareholder entered into in connection with the 2016 IPO, under which the Company is responsible for payment of expenses (other than underwriting discounts and commissions) relating to sales to the public by the shareholder of shares of the Company’s common stock beneficially owned by him. Such expenses include registration fees, legal and accounting fees, and printing costs payable by the Company and expensed when incurred.During the second quarter of 2018, the Company paid expenses totaling $0.7 million related to the completion of a follow-on secondary offering whereby the former majority shareholder was the seller.

Capital management and regulatory capital requirements

Our capital management consists of providing adequate equity to support our current and future operations. We are subject to various regulatory capital requirements administered by state and federal banking agencies, including the TDFI, Federal Reserve and the FDIC. Failure to meet minimum capital requirements may prompt certain actions by regulators that, if undertaken, could have a direct material adverse effect on our financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Our capital amounts and classification are also subject to qualitative judgments by the regulators about components of capital, risk weightings and other factors.

As a result of recent developments such as the Dodd-Frank Act and Basel III, we became subject to increasingly stringent regulatory capital requirements beginning in 2015. For further discussion of the changing regulatory framework in which we operate, see “Item 1. Business — Supervision and regulation” in our Annual Report.

80

The Federal Reserve, the FDIC and the Office of the Comptroller of the Currency have issued guidelines governing the levels of capital that banks must maintain. Those guidelines specify capital tiers, which include the classifications set forth in the following table. As of June 30, 2018 and December 31, 2017, we exceeded all regulatory requirements for capital ratios, as detailed in the table below:

	Actual						Required for capital adequacy purposes							To be well capitalized under prompt corrective action provision

We also have outstanding junior subordinated debentures with a carrying value of $30.9 million at June 30, 2018 and December 31, 2017, of which $30.0 million are included in our Tier 1 capital. The Federal Reserve Board issued rules in March 2005 providing stricter quantitative limits on the amount of securities that, similar to our junior subordinated debentures, are includable in Tier 1 capital. This guidance, which became fully effective in March 2009, did not impact the amount of debentures we include in Tier 1 capital. While our existing junior subordinated debentures are unaffected and are included in our Tier 1 capital, the Dodd-Frank Act specifies that any such securities issued after May 19, 2010 may not be included in Tier 1 capital.

In July 2013, the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency approved the implementation of the Basel III regulatory capital reforms and issued rules affecting certain changes required by the Dodd-Frank Act, which we refer to as the Basel III Rules, that call for broad and comprehensive revision of regulatory capital standards for U.S. banking organizations. The Basel III Rules implement a new common equity Tier 1 minimum capital requirement, a higher minimum Tier 1 capital requirement and other items that will affect the calculation of the numerator of a banking organization’s risk-based capital ratios. Additionally, the Basel III Rules apply limits to a banking organization’s capital distributions and certain discretionary bonus payments if the banking organization does not hold a specified amount of common equity Tier 1 capital in addition to the amount necessary to meet its minimum risk-based capital requirements.

The new common equity Tier 1 capital ratio includes common equity as defined under GAAP and does not include any type of non-common equity. When the Basel III Rules are fully effective in 2019, banks will be required to have common equity Tier 1 capital of 4.5% of average assets, Tier 1 capital of 6% of average assets, as compared to the current 4%, and total capital of 8% of risk-weighted assets to be categorized as adequately capitalized.

The Basel III Rules do not require the phase-out of trust preferred securities as Tier 1 capital of bank holding companies whose asset size is under $15 billion.

81

Further, the Basel III Rules changed the agencies’ general risk-based capital requirements for determining risk-weighted assets, which will affect the calculation of the denominator of a banking organization’s risk-based capital ratios. The Basel III Rules have revised the agencies’ rules for calculating risk-weighted assets to enhance risk sensitivity and incorporate certain international capital standards of the Basel Committee on Banking Supervision set forth in the standardized approach of the “International Convergence of Capital Measurement and Capital Standards: A Revised Framework”.

The calculation of risk-weighted assets in the denominator of the Basel III capital ratios is adjusted to reflect the higher risk nature of certain types of loans. Specifically, as applicable to the Company and the Bank:

• Commercial mortgages: Replaced the current 100% risk weight with a 150% risk weight for certain high volatility commercial real estate acquisition, development and construction loans.

• Nonperforming loans: Replaced the current 100% risk weight with a 150% risk weight for loans, other than residential mortgages, that are 90 days past due or on nonaccrual status.

• Securities pledged to overnight repurchase agreements: Replaced the current 0% risk weight with a 20% risk weight for repurchase agreements secured by mortgage back securities

• Unfunded lines of credit: Replaced the current 0% risk weight with 20% for unfunded lines of credit maturing in one year or less.

Certain calculations under the rules related to deductions from capital have phase-in periods through 2018.  Specifically, the capital treatment of MSRs is phased in through the transition periods. Under the prior rules, the Bank deducted 10% of the value of MSRs (net of deferred tax) from Tier 1 capital ratios. However, under Basel III, the Bank and the Company must deduct a much larger portion of the value of MSRs from Tier 1 capital.

• MSRs (net of deferred tax in excess of 10% of Tier 1 capital before threshold based deductions must be deducted from common equity. The disallowable portion of MSRs will be phased in incrementally (40% in 2015; 60% in 2016: 80% in 2017 and beyond).

• In addition, the combined balance of MSRs and deferred tax assets is limited to approximately 15% of the Bank’s and the Company’s common equity Tier 1 capital. These combined assets must be deducted from common equity to the extent that they exceed the 15% threshold.

• Any portion of the Bank’s and the Company’s MSRs that are not deducted from the calculation of common equity Tier 1 is subject to a 100% risk weight.

Generally, the new Basel III rules became effective on January 1, 2015, although parts of the Basel III Rules will be phased in through 2019.

On November 21, 2017, the federal banking regulators finalized a halt in the phase-in of certain provisions of the Rule for certain banks including FirstBank. The final rules had provided for a number of adjustments to deductions from Tier 1 capital. Deductions included, for example, the requirement that MSRs, certain deferred tax assets not dependent upon future taxable income and significant investments in non-consolidated financial entities be deducted from Tier 1 Capital to the extent that any one such category exceeds 10% of Tier 1 capital or all such categories in the aggregate exceed 15% of Tier 1 capital. Effective on January 1, 2018, the 2017 rule paused the full transition to the Basel III treatment.

As of June 30, 2018 and December 31, 2017, the Bank and Company met all capital adequacy requirements to which they are subject. Also, as of June 30, 2016, the date of the most recent notification from the FDIC, the Bank was well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category.

As part of our ongoing balance sheet and capital management during the quarter, the Company entered into a letter of intent to sell a portion of its mortgage servicing rights portfolio. The transaction provides for the sale of the rights on $3,217.6 million of serviced mortgage loans, of which the Company will continue to subservice until they can be transferred to the purchaser. The sale is expected to close during the third quarter of 2018 and is projected to make additional regulatory capital available to support the continued growth in the Banking segment of our business.

On May 24, 2018, The Economic Growth, Regulatory Relief, and Consumer Protection Act, also known as the Crapo Bill, was into law and will exempt banks with less than $10 billion in assets from certain regulatory requirements. For those banks, it establishes a Community Bank Leverage Ratio (“CBLR”), which is calculated as tangible equity capital divided by the average total assets. The CBLR minimum requirement would be set between 8% and 10%, and if an exempt bank maintains CBLR above the threshold, it can opt out of reporting or complying with other regulatory capital ratios. We will continue to monitor this new regulatory capital framework and evaluate as further details and guidance of the Crapo Bill are released.

82

Capital expenditures

Currently, we have not entered into any capital commitments exceeding $1 million; however, over the next twelve months we plan on investing approximately $5.5 million in branch improvements and expansion across our markets.

Shareholders’ equity

Our total shareholders’ equity was $631.0 million at June 30, 2018 and $596.7 million, at December 31, 2017. Book value per share was $20.56 at June 30, 2018 and $19.54 at December 31, 2017. The growth in shareholders’ equity was attributable to earnings retention offset by declared dividends, changes in accumulated other comprehensive income and activity related to equity-based compensation.

Off-balance sheet transactions

We enter into loan commitments and standby letters of credit in the normal course of our business. Loan commitments are made to accommodate the financial needs of our clients. Standby letters of credit commit us to make payments on behalf of clients when certain specified future events occur. Both arrangements have credit risk essentially the same as that involved in extending loans to clients and are subject to our normal credit policies. Collateral (e.g., securities, receivables, inventory, equipment, etc.) is obtained based on management’s credit assessment of the client.

Loan commitments and standby letters of credit do not necessarily represent our future cash requirements because while the borrower has the ability to draw upon these commitments at any time, these commitments often expire without being drawn upon. Our unfunded loan commitments and standby letters of credit outstanding at the dates indicated were as follows:

	June 30,		December 31,
	2018		2017
Loan commitments	$	1,088,486	$	977,276
Standby letters of credit		18,555		22,882

We closely monitor the amount of our remaining future commitments to borrowers in light of prevailing economic conditions and adjust these commitments as necessary. We will continue this process as new commitments are entered into or existing commitments are renewed.

For more information about our off-balance sheet transactions, see “Part I. Financial Information — Notes to Consolidated Unaudited Financial Statements — Note (8) – Commitments and contingencies” in this Report.

Risk management

There have been no significant changes in our Risk Management practices as described in “Item 1. Business — Risk Management” in our Annual Report.  

Credit risk

There have been no significant changes in our Credit Risk Management practices as described in our “Item 1. Business — Risk Management — Credit risk management” in our Annual Report.  

ITEM 3—QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate sensitivity

Our market risk arises primarily from interest rate risk inherent in the normal course of lending and deposit-taking activities. Management believes that our ability to successfully respond to changes in interest rates will have a significant impact on our financial results. To that end, management actively monitors and manages our interest rate risk exposure.

The Asset Liability Management Committee (“ALMC”), which is authorized by the Company’s Board of Directors, monitors our interest rate sensitivity and makes decisions relating to that process. The ALMC’s goal is to structure our asset/ liability composition to maximize net interest income while managing interest rate risk so as to minimize the adverse impact of changes in interest rates on net interest income and capital in either a rising or declining interest rate environment. Profitability is affected by fluctuations in interest rates. A sudden and substantial change in interest rates may adversely impact our earnings because the interest rates borne by assets and liabilities do not change at the same speed, to the same extent or on the same basis.

83

We monitor the impact of changes in interest rates on our net interest income and economic value of equity (“EVE”), using rate shock analysis. Net interest income simulations measure the short-term earnings exposure from changes in market rates of interest in a rigorous and explicit fashion. Our current financial position is combined with assumptions regarding future business to calculate net interest income under varying hypothetical rate scenarios. EVE measures our long-term earnings exposure from changes in market rates of interest. EVE is defined as the present value of assets minus the present value of liabilities at a point in time. A decrease in EVE due to a specified rate change indicates a decline in the long-term earnings capacity of the balance sheet assuming that the rate change remains in affect over the life of the current balance sheet.

The following analysis depicts the estimated impact on net interest income and EVE of immediate changes in interest rates at the specified levels for the periods presented:

	Percentage change in:
Change in interest rates	Net interest income(1)
	Year 1						Year 2
	June 30,			December 31,			June 30,			December 31,
(in basis points)	2018			2017			2018			2017
+400		4.5	%		8.8	%		8.8	%		13.9	%
+300		3.5	%		6.6	%		6.8	%		10.6	%
+200		2.5	%		4.4	%		4.9	%		7.3	%
+100		1.1	%		2.0	%		2.4	%		3.6	%
-100		(5.1	)%		(6.7	)%		(7.2	)%		(9.2	)%
-200		(13.8	)%		(13.4	)%		(17.7	)%		(17.5	)%

	Percentage change in:
Change in interest rates	Economic value of equity(2)
	June 30,			December 31,
(in basis points)	2018			2017
+400		(5.0	)%		(8.8	)%
+300		(3.4	)%		(6.2	)%
+200		(1.6	)%		(3.5	)%
+100		(0.5	)%		(1.6	)%
-100		(3.1	)%		(3.3	)%
-200		(13.0	)%		(15.1	)%

(1) The percentage change represents the projected net interest income for 12 months and 24 months on a flat balance sheet in a stable interest rate environment versus the projected net income in the various rate scenarios.

(2) The percentage change in this column represents our EVE in a stable interest rate environment versus EVE in the various rate scenarios.

The results for the net interest income simulations for June 30, 2018 and December 31, 2017 resulted in an asset sensitive position. One of the primary influences of our asset sensitivity is the variability in our loans held for sale balances. As our mortgage loans held for sale increase, we become more asset sensitive. Conversely, as mortgage rates rise, we expect our mortgage originations and mortgage loans held for sale to decline, which will make us less asset sensitive. Beta assumptions on loans and deposits were consistent for both time periods. The ALMC also reviewed beta assumptions for time deposits and loans with industry standards and revised them accordingly.

The preceding measures assume no change in the size or asset/liability compositions of the balance she et. Thus, the measures do not reflect the actions the ALMC may undertake in response to such changes in interest rates. The scenarios assume instantaneous movements in interest rates in increments of 100, 200, 300 and 400 basis points. With the present position of the target federal funds rate, the declining rate scenarios seem improbable. Furthermore, it has been the Federal Reserve’s policy to adjust the target federal funds rate incrementally over time. As interest rates are adjusted over a period of time, it is our strategy to proactively change the volume and mix of our balance sheet in order to mitigate our interest rate risk. The computation of the prospective effects of hypothetical interest rate changes requires numerous assumptions regarding characteristics of new business and the behavior of existing positions. These business assumptions are based upon our experience, business plans and published industry experience. Key assumptions employed in the model include asset prepayment speeds, competitive factors, the relative price sensitivity of certain assets and liabilities and the expected life of non-maturity deposits. Because these assumptions are inherently uncertain, actual results may differ from simulated results.

We utilize derivative financial instruments as part of an ongoing effort to mitigate interest rate risk exposure to interest rate fluctuations and facilitate the needs of our customers.

84

The Company enters into derivative instruments that are not designated as hedging instruments to help its commercial customers manage their exposure to interest rate fluctuations.  To mitigate the interest rate risk associated with customer contracts, the Company enters into an offsetting derivative contract.  The Company manages its credit risk, or potential risk of default by its commercial customers through credit limit approval and monitoring procedures.  

The Company has entered into interest rate swap contracts to hedge interest rate exposure on short term liabilities, as well as interest rate swap contracts to hedge interest rate exposure on subordinated debentures.  These interest rate swaps are all accounted for as cash flow hedges, with the Company receiving a variable rate of interest and paying a fixed rate of interest.  

The Company enters into rate lock commitments and forward loan sales contracts as part of our ongoing efforts to mitigate our interest rate risk exposure inherent in our mortgage pipeline and held for sale portfolio. Under the interest rate lock commitments, interest rates for a mortgage loan are locked in with the client for a period of time, typically thirty days. Once an interest rate lock commitment is entered into with a client, we also enter into a forward commitment to sell the residential mortgage loan to secondary market investors. Forward loan sale contracts are contracts for delayed sale and delivery of mortgage loans to a counter party. We agree to deliver on a specified future date, a specified instrument, at a specified price or yield. The credit risk inherent to us arises from the potential inability of counterparties to meet the terms of their contracts. In the event of non-acceptance by the counterparty, we would be subject to the credit and inherent (or market) risk of the loans retained.

Additionally, the Company enters into forward commitments, options and futures contracts that are not designated as hedging instruments, which serve as economic hedges of the change in fair value of its MSRs.

For more information about our derivative financial instruments, see Note 9, “Derivative Instruments,” in the notes to our consolidated financial statements.  

ITEM 4—CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report was carried out under the supervision and with the participation of the Company’s Chief Executive Officer, Chief Financial Officer and other members of the Company’s senior management. The Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Report, the Company’s disclosure controls and procedures were effective in ensuring that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is: (i) accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure; and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) or Rule 15d-15(f) under the Exchange Act) that occurred during the the fiscal quarter ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company does not expect that its disclosure controls and procedures and internal control over financial reporting will prevent all errors and fraud. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met. Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any control procedure also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.

PART II—OTHER INFORMATION

ITEM 1—LEGAL PROCEEDINGS

Various legal proceedings to which we or our subsidiaries are party arise from time to time in the normal course of business. As of the date of this Report, there are no material pending legal proceedings to which we or any of our subsidiaries is a party or of which any of our or our subsidiaries’ properties are subject.

ITEM 1A—RISK FACTORS

The discussion of the Company’s business and operations should be read together with the risk factor described below and the risk factors contained in Item 1A of its Annual Report on Form 10-K for the year ended December 31, 2017, previously filed with the SEC, which describes various risks and uncertainties to which the Company is or may be subject. These risks and uncertainties have the potential to affect the Company’s business, financial condition, results of operations, and prospects in a material adverse manner.

Our deposit portfolio includes significant concentrations and a large percentage of our deposits are attributable to a relatively small number of clients.

As a commercial bank, we provide services to a number of clients whose deposit levels may vary considerably and have seasonality based on their nature. At June 30, 2018, 6 commercial and individual clients, maintained balances (aggregating all related accounts, including multiple business entities and personal funds of business owners) in excess of $25.0 million. Which amounted to $484.3 million in total deposits at June 30, 2018.  These clients are not concentrated in any particular industry or business but include certain related parties of the Company. In addition, mortgage escrow deposits that our third-party servicing provider, Cenlar, transfer to the Bank totaled $88.4 million at June 30, 2018. This balance is expected to decrease in the third quarter of 2018 upon the closing of the pending sale of mortgage servicing rights. See Note 6, “Mortgage Servicing Rights” in these Notes to the consolidated unaudited financial statements for further details regarding this sale. Further, our deposits from municipal and governmental entities (i.e., “public deposits”) totaled $408.7 million at June 30, 2018.  Of these public deposits, 3 public entities maintained balances in excess of $25.0 million at June 30, 2018 totaling $152.8 million. These deposits can and do fluctuate substantially. The loss of any combination of these depositors, or a significant decline in the deposit balances due to unexpected fluctuations related to these customers’ businesses, would adversely affect our liquidity and may require us to raise deposit rates to quickly attract new customer deposits, purchase brokered deposits, purchase federal funds or borrow funds on a short-term basis to replace such deposits. Depending on the interest rate environment and competitive factors, lower cost deposits may need to be replaced with higher cost funding, resulting in a decrease in net interest income and net income. While these events could have a material impact on the Bank’s results, the Bank expects, in the ordinary course of business, that these deposits will fluctuate and believes it is capable of mitigating this risk, as well as the risk of losing one of these depositors, through additional liquidity, and business generation in the future. However, should a significant number of these customers leave the Bank, it could have a material adverse impact on the Bank.

ITEM 2—UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Initial Public Offering

On September 15, 2016, our registration statement on Form S-1 (Registration No. 333-213210) was declared effective by the SEC for our underwritten initial public offering in which we sold a total of 6,764,704 shares of our common stock at a price to the public of $19.00 per share. J.P. Morgan Securities LLC, UBS Securities LLC, and Keefe, Bruyette & Woods, Inc., acted as the joint book-running managers for the offering, and Raymond James & Associates, Inc., Sandler O’Neill & Partners, L.P., and Stephens Inc. acted as co-managers.

The offering commenced on September 15, 2016 and closed on September 21, 2016. All of the shares registered pursuant to the registration statement were sold at an aggregate offering price of $128.5 million. We received net proceeds of approximately $115.5 million after deducting underwriting discounts and commissions of $9.0 million and other offering expenses of $4.0 million. No payments with respect to expenses were made by us to directors, officers or persons owning ten percent or more of either class of our common stock or to their associates, or to our affiliates. However, $55 million of the net proceeds from the offering were used to fund a cash distribution to James W. Ayers, our former majority shareholder and executive chairman, which cash distribution was intended to be non-taxable to Mr. Ayers, and $10.1 million of the net proceeds from the offering were used to fund the repayment of all amounts outstanding under our subordinated notes held by Mr. Ayers. During the third quarter of 2017, a portion was used to fund the merger with the Clayton Banks. Remaining Proceeds of approximately $22.4 million from the offering remain in interest bearing deposits in other financial institutions and may be used for general business purposes or to fund future acquisitions.

Accounting Policies [Abstract]

Basis of presentation

Note (1)—Basis of presentation:

FB Financial Corporation (the “Company”) is a bank holding company, headquartered in Nashville, Tennessee. The Company operates through its wholly owned bank subsidiary, FirstBank (the “Bank”), with 56 full-service bank branches across Tennessee, North Alabama and North Georgia, and a national mortgage business with office locations across the Southeast.

The consolidated financial statements, including the notes thereto of the Company, have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) interim reporting requirements, and therefore do not include all information and notes included in the annual consolidated financial statements in conformity with GAAP. These interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K.

The unaudited consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. The results for interim periods are not necessarily indicative of results for a full year.

The accompanying consolidated financial statements have been prepared in conformity with GAAP and general banking industry. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported results of operations for the periods then ended. Actual results could differ significantly from those estimates.

Certain prior period amounts have been reclassified to conform to the current period presentation without any impact on the reported amounts of net income or shareholders’ equity.

Effective July 31, 2017, the Bank completed its previously announced acquisitions of Clayton Bank and Trust and American City Bank headquartered in Knoxville, Tennessee and Tullahoma, Tennessee, respectively.  See Note 2, “Mergers and acquisitions” in these Notes to the consolidated unaudited financial statements for further details regarding acquisitions.

Prior to May 31, 2018, the Company was considered a “controlled company” and was controlled by the Company’s Executive Chairman and former majority shareholder, James W. Ayers. During the second quarter of 2018, the Company completed a secondary offering of 3,680,000 shares of common stock pursuant to the Company’s effective registration statement on Form S-3 whereby James W. Ayers was the seller. As a result of this transaction, the Company ceased to qualify as a “controlled company” as the selling shareholder’s ownership was reduced to approximately 44% of the voting power of the Company’s issued and outstanding shares of common stock. The Company continues to qualify as an emerging growth company as defined by the “Jumpstart Our Business Startups Art” (“JOBS Act”).

Subsequent events

The Company has evaluated, for consideration of recognition or disclosure, subsequent events that occurred through the date of issuance of these financial statements. The Company has determined that there were no other subsequent events other than described below that occurred after June 30, 2018, but prior to the issuance of these financial statements that would have a material impact on the Company’s consolidated financial statements.

On July 19, 2018, the Company declared a regular quarterly dividend of $0.06 per share to be paid on August 15, 2018 to shareholders of record as of July 31, 2018, totaling approximately $1,909.

On August 7, 2018, the Federal Home Loan Bank of Cincinnati increased the capacity on the Company’s line of credit from $300,000 to $800,000.

Earnings per share

Basic earnings per common share (“EPS”) excludes dilution and is computed by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the dilutive effect of additional potential common shares issuable under the restricted stock units granted but not yet vested and distributable. Diluted EPS is computed by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding for the year, plus an incremental number of common-equivalent shares computed using the treasury stock method.

Unvested share-based payment awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered to participate with common shareholders in undistributed earnings for purposes of computing EPS. Companies that have such participating securities, including FB Financial, are required to calculate basic and diluted EPS using the two-class method. Certain restricted stock awards granted by the Company include non-forfeitable dividend equivalents and are considered participating securities. Calculations of EPS under the two-class method (i) exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities and (ii) exclude from the denominator the dilutive impact of the participating securities.

The following is a summary of the basic and diluted earnings per common share calculation for each of the periods presented:

Rebooked GNMA loans included in loans held for sale

Government National Mortgage Association (“GNMA”) optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing and was the original transferor.  At the servicer’s option and without GNMA’s prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan.  Under FASB ASC Topic 860, “Transfers and Servicing,” this buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional.  When the Company is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as loans held for sale, regardless of whether the Company intends to exercise the buy-back option if the buyback option provides the transferor a more-than-trivial benefit. At June 30, 2018, there were $52,212 of delinquent GNMA loans that had previously been sold; however, the Company determined there was not a “more-than-trivial benefit” based on an analysis of interest rates and an assessment of potential reputational risk associated with these loans. As such, the Company did not rebook the GNMA loans as of June 30, 2018. At December 31, 2017, rebooked GNMA loans held for sale amounted to $43,035 with an offsetting liability included in accrued expenses and other liabilities in the same amount. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option.

Recently adopted accounting principles:

Except as set forth below, the Company did not adopt any new accounting policies that were not disclosed in the Company’s 2017 audited consolidated financial statements included on Form 10-K.

On January 1, 2018, the Company adopted the following newly issued accounting standards:

In May 2014, the FASB issued an update to Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”. The Company adopted this guidance on January 1, 2018 and all subsequent amendments to the ASU (collectively, “ASC 606”) which (i) creates a single framework for recognizing revenue from contracts with customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets, such as OREO.  The majority of the Company’s revenues come from interest income and other sources, including loans, leases, securities and derivatives that are outside the scope of ASC 606.  The Company’s services that fall within the scope of ASC 606 are presented within Noninterest income and are recognized as revenue as the Company satisfies its obligation to the customer.  Services within the scope of ASC 606 include deposit service charges on deposits, interchange income, investment services and trust income, and the sale of OREO, all within the Banking Segment.  The Company has evaluated the effect of this updated on these fee-based income streams and concluded that adoption did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded.

The following is a summary of the implementation considerations for the revenue streams that fall within the scope of Topic 606:

• Service charges on deposits, investment services and trust income, and interchange fees — Fees from these services are either transaction based, for which the performance obligations are satisfied when the individual transaction is processed, or set periodic service charges, for which the performance obligations are satisfied over the period the service is provided. Transaction based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on the Company's revenue recognition practice for these services.

• Gains on sales of other real estate — ASU 2014-09 creates Topic 610-20, under which a gain on sale should be recognized when a contract for sale exists and control of the asset has been transferred to the buyer. Topic 606 list several criteria which must exist to conclude that a contract for sale exists, including a determination that the institution will collect substantially all of the consideration to which it is entitled. This presents a key difference between the current and new guidance related to the recognition of the gain when the institution finances the sale of the property. Rather than basing recognition on the amount of the buyer's initial investment, which was the primary consideration under prior guidance, the analysis is now based on various factors including not only the loan to value, but also the credit quality of the borrower, the structure of the loan, and any other factors that may affect collectability. While these differences may affect the decision to recognize or defer gains on sales of other real estate in circumstances where the Company has financed the sale, these amounts have not been material to its financial statements.

In January 2016, the FASB released ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.” The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and adjust the fair value disclosures for financial instruments carried at amortized cost such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value such that these securities can be carried at cost less any impairment. Results for reporting periods beginning after January 1, 2018 are presented under this method while prior period disclosures are presented under legacy GAAP. On January 1, 2018, the Company recorded a net loss in beginning retained earnings of $109 in connection with this transition.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230).” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. This adoption did not have an impact on our financial statements.

In May 2017, the FASB issued ASU 2017-09, “Stock Compensation - Scope of Modification Accounting (Topic 718): Scope of Modification Accounting.” The amendments in this ASU provide guidance on when changes to the terms or conditions of a share-based payment award are to be accounted for as modifications. Under ASU 2017-09, entities are not required to apply modification accounting to a share-based payment award when the award’s fair value, vesting conditions, and classification as an entity or a liability instrument remain the same after the change. ASU 2017-09 is effective for all entities beginning after December 15, 2017 including interim periods within the fiscal year. The adoption of this update on January 1, 2018 did not have a significant impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU make more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. There was no impact to the Company’s financial statements or disclosures as a result of this early adoption as of January 1, 2018.

Newly issued not yet effective accounting standards:

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The update will require lessees to recognize right-of-use assets and lease liabilities for all leases not considered short term leases. The provisions of the update also include (a) defining direct costs to only include those incremental costs that would not have been incurred if the lease had not been entered into, (b) circumstances under which the transfer contract in a sale-leaseback transaction should be accounted for as the sale of an asset by the seller-lessee and the purchase of an asset by the buyer-lessor, and (c) additional disclosure requirements. The provisions of this update become effective for interim and annual periods beginning after December 15, 2018. Management is currently evaluating the potential impact of this update.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as, the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will become effective for interim and annual periods beginning after December 15, 2019. Management is currently evaluating the potential impact of this update.

In March 2017, the FASB issued ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. The adoption of this update will not have an impact on the Company’s consolidated financial statements.

Mergers and acquisitions

Business Combinations [Abstract]

Mergers and acquisitions

Note (2)—Mergers and acquisitions:

Clayton Bank and Trust and American City Bank

On July 31, 2017, the Bank completed its merger with Clayton Bank and Trust (“CBT”) and American City Bank (“ACB” and together with CBT, the “Clayton Banks”), pursuant to the Stock Purchase Agreement with Clayton HC, Inc., a Tennessee corporation (“Seller”), and James L. Clayton, the majority shareholder of Seller, dated February 8, 2017, as amended on May 26, 2017, with a purchase price of approximately $236,484.  The Company issued 1,521,200 shares of common stock and paid cash of $184,200 to purchase all of the outstanding shares of the Clayton Banks.  At closing, the Clayton Banks merged with and into FirstBank, with FirstBank continuing as the surviving banking entity.

Prior to the merger, the Clayton Banks operated 18 banking locations across Tennessee. The merger with the Clayton Banks has allowed the Company to further its strategic initiatives by expanding its geographic footprint in Knoxville and other Tennessee markets and accelerating the growth of the Company’s Banking segment.

Goodwill of $90,323 recorded in connection with the transaction resulted primarily from anticipated synergies arising from the combination of certain operational areas of the Clayton Banks and the Company as well as the purchase premium inherent to buying a complete and successful banking operation. Goodwill is included in the Banking segment as substantially all of the operations resulting from the Clayton Banks merger is included in the Banking segment.

In connection with the transaction, the Company incurred $0 and $1,193 in merger and conversion expenses during the three and six months ended June 30, 2018 compared with $767 and $1,254 for the same periods in 2017.

For income tax purposes, the merger with the Clayton Banks was treated as an asset purchase. As an asset purchase for income tax purposes, the carrying value of assets and liabilities for the Clayton Banks are the same for both financial reporting and income tax purposes; therefore, no deferred taxes were recorded at the date of acquisition. Additionally, this treatment allows for the deductibility of the goodwill and core deposit intangible for income tax purposes over 15 years.

The Company accounted for the Clayton Banks transaction under the acquisition method under ASC Topic 805. Accordingly, the fair value of the assets acquired and liabilities assumed along with the resulting goodwill was recorded as of the date of the merger. The Company’s operating results for the three and six months ended June 30, 2018 include the operating results of the acquired assets and assumed liabilities of the Clayton Banks.

As of December 31, 2017, the Company finalized its valuation of all assets acquired and liabilities assumed, resulting in no material changes to preliminary purchase accounting adjustments. The following tables present the final estimated fair value of net assets acquired as of the July 31, 2017 acquisition date and the consideration paid and an allocation of the purchase price to net assets acquired:

The amortized cost and fair value of debt securities by contractual maturity at June 30, 2018 and December 31, 2017 are shown below. Maturities may differ from contractual maturities in mortgage-backed securities because the mortgage underlying the security may be called or repaid without any penalties. Therefore, mortgage-backed securities are not included in the maturity categories in the following maturity summary.

As of June 30, 2018 and December 31, 2017, the Company’s securities portfolio consisted of 329 and 294 securities, 181 and 124 of which were in an unrealized loss position, respectively.

The Company evaluates securities with unrealized losses for other-than-temporary impairment (OTTI) on a quarterly basis and recorded no OTTI for the three or six months ended June 30, 2018 and 2017. Impairment is assessed at the individual security level. The Company considers an investment security impaired if the fair value of the security is less than its cost or amortized cost basis. For debt securities, the unrealized losses associated with these investment securities are primarily driven by interest rates and are not due to the credit quality of the securities. The Company currently does not intend to sell those investments with unrealized losses, and it is unlikely that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity.

Interest revenue, through accretion of the difference between the carrying value of the loans and the expected cash flows, is being recognized on all PCI loans. Accretion of interest income amounting to $2,639 and $4,840 was recognized on purchased credit impaired loans during the three and six months ended June 30, 2018, respectively, compared with $589 and $1,612 for the three and six months ended June 30, 2017, respectively. This includes both the contractual interest income and the purchase accounting contribution through accretion of the liquidity discount and credit mark for changes in estimated cash flows. The total purchase accounting contribution through accretion for all purchased loans was $1,928 and $3,615 for three and six months ended June 30, 2018, respectively, compared with $848 and $2,008 for the three and six months ended June 30, 2017.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. The Company’s risk rating definitions include:

Watch.    Loans rated as watch includes loans in which management believes conditions have occurred, or may occur, which could result in the loan being downgraded to a worse rated category. Also included in watch are loans rated as special mention, which have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Substandard.    Loans rated as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so rated 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. Also included in this category are loans considered doubtful, which have all the weaknesses previously described and management believes those weaknesses may make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loans not meeting the criteria above are considered to be pass rated loans.

The following table shows credit quality indicators by portfolio class at June 30, 2018 and December 31, 2017:

PCI loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement remains unpaid after the due date of the scheduled payment. However, these loans are considered to be performing, even though they may be contractually past due, as any non-payment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or future period yield adjustments. The accrual of interest is discontinued on PCI loans if management can no longer reliably estimate future cash flows on the loan. No PCI loans were classified as nonaccrual at June 30, 2018 or December 31, 2017 as the carrying value of the respective loan or pool of loans cash flows were considered estimable and probable of collection.

Nonperforming loans include loans that are no longer accruing interest (non-accrual loans) and loans past due ninety or more days and still accruing interest. Nonperforming loans and impaired loans are defined differently. Some loans may be included in both categories, whereas other loans may only be included in one category.

The following table provides the period-end amounts of loans that are past due thirty to eighty-nine days, past due ninety or more days and still accruing interest, loans not accruing interest, loans current on payments accruing interest and purchased credit impaired loans by category at June 30, 2018 and December 31, 2017:

As of June 30, 2018 and December 31, 2017, the Company has a recorded investment in troubled debt restructurings of $8,603 and $8,604, respectively. The modifications included extensions of the maturity date and/or a stated rate of interest to one lower than the current market rate. The Company has allocated $90 and $172 of specific reserves for those loans at June 30, 2018 and December 31, 2017, respectively, and has committed to lend additional amounts totaling up to $4 and $2, respectively to these customers. Of these loans, $3,000 and $3,205 were classified as non-accrual loans as of June 30, 2018 and December 31, 2017, respectively.

The following tables present the financial effect of TDRs recorded during the periods indicated:

There were no TDRs recorded during the three months ended June 30, 2017. Additionally, there were no loans modified as troubled debt restructurings for which there was a payment default within twelve months following the modification during the six months ended June 30, 2018 or 2017.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

The terms of certain other loans were modified during the six months ended June 30, 2018 and 2017 that did not meet the definition of a troubled debt restructuring. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant.

In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the company’s internal underwriting policy.

Commitments and Contingencies

Note (8)—Commitments and contingencies:

Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates.

Commitments may expire without being used. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment.

In connection with the sale of mortgage loans to third party investors, the Bank makes usual and customary representations and warranties as to the propriety of its origination activities. Occasionally, the investors require the Bank to repurchase loans sold to them under the terms of the warranties. When this happens, the loans are recorded at fair value with a corresponding charge to a valuation reserve. The total principal amount of loans repurchased (or indemnified for) was $1,543 and $921 and $2,662 and $1,770for the three and six months ended June 30, 2018 and 2017, respectively. The Bank has established a reserve associated with loan repurchases. This reserve is recorded in accrued expenses and other liabilities on the consolidated balance sheet. The following table summarizes the activity in the repurchase reserve:

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives

Note (9)—Derivatives:

The Company utilizes derivative financial instruments as part of its ongoing efforts to manage its interest rate risk exposure as well as the exposure for its customers. Derivative financial instruments are included in the Consolidated Balance Sheets line item “Other assets” or “Other liabilities” at fair value in accordance with ASC 815, “Derivatives and Hedging.”

The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate-lock commitments). Under such commitments, interest rates for a mortgage loan are typically locked in for forty-five days with the customer. These interest rate lock commitments are recorded at fair value in the Company’s Consolidated Balance Sheets.  The Company also enters into best effort or mandatory delivery forward commitments to sell residential mortgage loans to secondary market investors. Gains and losses arising from changes in the valuation of the rate-lock commitments and forward commitments are recognized currently in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income.

The Company enters into forward commitments, futures and options contracts that are not designated as hedging instruments as economic hedges of the change in the fair value of its MSRs. Gains and losses associated with these instruments are included in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income.

The Company enters into derivative instruments that are not designated as hedging instruments to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with customer contracts, the Company enters into an offsetting derivative contract. The Company manages its credit risk, or potential risk of default by its commercial customers through credit limit approval and monitoring procedures.

In June of 2017, the Company entered into two interest rate swap agreements with notional amounts totaling $30,000 to hedge interest rate exposure on outstanding subordinate debentures included in long-term debt totaling $30,930. Under these agreements, the Company receives a variable rate of interest and pays a fixed rate of interest. The interest rate swap contracts, which mature in June of 2024, are designated as cash flow hedges with the objective of reducing the variability in cash flows resulting from changes in interest rates. As of June 30, 2018 and December 31, 2017, the fair value of these contracts was $1,296 and $305, respectively.

In July of 2017, the Company entered into three interest rate swap contracts on floating rate liabilities at the Bank level with notional amounts of $30,000, $35,000 and $35,000 for a period of three, four and five years, respectively. These interest rate swaps were designated as cash flow hedges with the objective of reducing the variability of cash flows associated with $100,000 of FHLB borrowings obtained in conjunction with the Clayton Bank acquisition. Under these contracts, the Company receives a variable rate of interest and pays a fixed rate of interest. As of December 31, 2017, the fair value of these contracts was $1,127 included in those designated as hedging below. During the six months ended June 30, 2018, these swaps were cancelled, locking in a tax-adjusted gain of $1,564 in other comprehensive income to be accreted over the three, four and five-year terms of the underlying contracts. As of June 30, 2018, there was $1,559 remaining in other comprehensive income to be accreted into income.

Certain financial instruments, including derivatives, may be eligible for offset in the Consolidated Balance Sheet when the “right of setoff” exists or when the instruments are subject to an enforceable master netting agreement, which includes the right of the non-defaulting party or non-affected party to offset recognized amounts, including collateral posted with the counterparty, to determine a net receivable or net payable upon early termination of the agreement. Certain of the Company’s derivative instruments are subject to master netting agreements. The Company has not elected to offset such financial instruments in the Consolidated Balance Sheets.

Most derivative contracts with clients are secured by collateral. Additionally, in accordance with the interest rate agreements with derivatives dealers, the Company may be required to post margin to these counterparties. At June 30, 2018 and December 31, 2017, the Company had minimum collateral posting thresholds with certain of its derivative counterparties and posted collateral of $10,896 and $4,309, respectively, against its obligations under these agreements. Cash collateral related to derivative contracts is recorded in other assets in the consolidated balance sheets.

Fair Value of Financial Instruments

6 Months Ended

Jun. 30, 2018

Fair Value Disclosures [Abstract]

Fair value of financial instruments

Note (10)—Fair value of financial instruments:

FASB ASC 820-10 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820-10 also establishes a framework for measuring the fair value of assets and liabilities according to a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that are derived from assumptions based on management’s estimate of assumptions that market participants would use in pricing the asset or liability based on the best information available under the circumstances.

The hierarchy is broken down into the following three levels, based on the reliability of inputs:

Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs for assets or liabilities that are derived from assumptions based on management’s estimate of assumptions that market participants would use in pricing the assets or liabilities.    

The Company records the fair values of financial assets and liabilities on a recurring and non-recurring basis using the following methods and assumptions:

During the first quarter of 2018, the Company adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.” The amendments included within this standard, which are applied prospectively, require the Company to disclose fair value of financial instruments measured at amortized cost on the balance sheet to measure the fair value using an exit price notion. Prior to adopting the amendments included in the standard, the Company measured fair value under an entry price notion.

Investment securities—Investment securities are recorded at fair value on a recurring basis. Fair values for securities are based on quoted market prices, where available. If quoted prices are not available, fair values are based on quoted market prices of similar instruments or are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the pricing relationship or correlation among other benchmark quoted securities. Investment securities valued using quoted market prices of similar instruments or that are valued using matrix pricing are classified as Level 2. When significant inputs to the valuation are unobservable, the available-for-sale securities are classified within Level 3 of the fair value hierarchy.

Where no active market exists for a security or other benchmark securities, fair value is estimated by the Company with reference to discount margins for other high risk securities.

Loans held for sale—Loans held for sale are carried at fair value. Fair value is determined using current secondary market prices for loans with similar characteristics, that is, using Level 2 inputs.

Derivatives—The fair value of the interest rate swaps are based upon fair values provided from entities that engage in interest rate swap activity and is based upon projected future cash flows and interest rates. Fair value of commitments is based on fees currently charged to enter into similar agreements, and for fixed-rate commitments, the difference between current levels of interest rates and the committed rates is also considered. These financial instruments are classified as Level 2.

Other real estate owned—Other real estate owned (“OREO”) is comprised of commercial and residential real estate obtained in partial or total satisfaction of loan obligations and excess land and facilities held for sale. OREO acquired in settlement of indebtedness is recorded at the lower of the carrying amount of the loan or the fair value of the real estate less costs to sell. Fair value is determined on a nonrecurring basis based on appraisals by qualified licensed appraisers and is adjusted for management’s estimates of costs to sell and holding period discounts. The valuations are classified as Level 3.

Mortgage servicing rights—Servicing rights are carried at fair value. Fair value is determined using an income approach with various assumptions including expected cash flows, market discount rates, prepayment speeds, servicing costs, and other factors. Mortgage servicing rights are disclosed as Level 3.

Impaired loans—Loans considered impaired under FASB ASC 310, Receivables, are loans for which, based on current information and events, it is probable that the creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. Fair value adjustments for impaired loans are recorded on a non-recurring basis as either partial write downs based on observable market prices or current appraisal of the collateral. Impaired loans are classified as Level 3.

The following table contains the estimated fair values and the related carrying values of the Company's financial instruments. Items which are not financial instruments are not included. Due to the adoption of ASU 2016-01 as of January 1, 2018, the fair value as presented below is measured using the exit price notion in the periods after adoption and may not be comparable with prior periods presented as a result of the change in methodology.

(1) See Note 1, “Basis of Presentation” in the Notes to the consolidated financial statements for additional details regarding the adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities.

As of December 31, 2017, there was no established market for certain other securities, and as such, the Company had estimated that historical costs approximated market value. As of January 1, 2018, the Company adopted ASU 2016-01 (See Note 1) and reclassified $3,604 of these other securities without readily determinable market values to other assets.

The following table presents information as of June 30, 2018 about significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis:

Financial instrument	Fair Value		Valuation technique	Significant Unobservable inputs	Range of inputs
Impaired loans	$	431	Valuation of collateral	Discount for comparable sales	0%-30%
Other real estate owned	$	798	Appraised value of property less costs to sell	Discount for costs to sell	0%-15%

The following table presents information as of December 31, 2017 about significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis:

Financial instrument	FairValue		Valuation technique	Significant Unobservable inputs	Range of inputs
Impaired loans	$	77,027	Valuation of collateral	Discount for comparable sales	0%-30%
Other real estate owned	$	13,174	Appraised value of property less costs to sell	Discount for costs to sell	0%-15%

Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the lending administrative department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry wide statistics.

Fair value option:

The Company elected to measure all loans originated for sale at fair value under the fair value option as permitted under ASC 825. Electing to measure these assets at fair value reduces certain timing differences and better matches the changes in fair value of the loans with changes in the fair value of derivative instruments used to economically hedge them.

Net gains of $2,076 and $4,197 and $1,864 and $9,470 and resulting from fair value changes of the mortgage loans were recorded in income during the three and six months ended June 30, 2018 and 2017, respectively. The amount does not reflect changes in fair values of related derivative instruments used to hedge exposure to market-related risks associated with these mortgage loans. The change in fair value of both loans held for sale and the related derivative instruments are recorded in Mortgage Banking Income in the Consolidated Statements of Income. Election of the fair value option allows the Company to reduce the accounting volatility that would otherwise result from the asymmetry created by accounting for the financial instruments at the lower of cost or fair value and the derivatives at fair value. The fair value option election does not apply to the GNMA optional repurchase loans recorded as of December 31, 2017 which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option. At June 30, 2018, there were $52,212 of delinquent GNMA loans that had previously been sold. The Company determined there not to be a more-than-trivial benefit based on an analysis of interest rates and an assessment of potential reputational risk associated with these loans. As such, the Company had $0 in rebooked GNMA loans included in loans held for sale as of June 30, 2018. GNMA optional repurchase loans totaled $43,035 at December 31, 2017 and are included in loans held for sale on the accompanying Consolidated Balance Sheet. See Note 1, “Basis of presentation” in the Notes to the consolidated financial statements for additional details regarding rebooked GNMA loans.

The Company’s valuation of loans held for sale incorporates an assumption for credit risk; however, given the short-term period that the Company holds these loans, valuation adjustments attributable to instrument-specific credit risk is nominal. Interest income on loans held for sale measured at fair value is accrued as it is earned based on contractual rates and is reflected in loan interest income in the Consolidated Statements of Income.

The following table summarizes the differences between the fair value and the principal balance for loans held for sale measured at fair value as of June 30, 2018 and December 31, 2017:

June 30, 2018	Aggregate fair value		Aggregate Unpaid Principal Balance		Difference

Segment Reporting [Abstract]

Segment Reporting

Note (11)—Segment reporting:

The Company and the Bank are engaged in the business of banking and provide a full range of financial services. The Company determines reportable segments based on the significance of the segment’s operating results to the overall Company, the products and services offered, customer characteristics, processes and service delivery of the segments and the regular financial performance review and allocation of resources by the Chief Executive Officer (“CEO”), the Company’s chief operating decision maker. The Company has identified two distinct reportable segments—Banking and Mortgage. The Company’s primary segment is Banking, which provides a full range of deposit and lending products and services to corporate, commercial and consumer customers. The Company offers full-service conforming residential mortgage products, including conforming residential loans and services through the Mortgage segment utilizing mortgage offices outside of the geographic footprint of the Banking operations as well as internet and correspondent delivery channels. Additionally, the Mortgage Segment includes the servicing of residential retail mortgage loans and the packaging and securitization of loans to governmental agencies. The residential mortgage products and services originated in our Banking footprint and related revenues and expenses are included in our Banking segment. The Company’s mortgage division represents a distinct reportable segment which differs from the Company’s primary business of commercial and retail banking.

The financial performance of the Mortgage segment is assessed based on results of operations reflecting direct revenues and expenses and allocated expenses. This approach gives management a better indication of the operating performance of the segment. When assessing the Banking segment’s financial performance, the CEO utilizes reports with indirect revenues and expenses including but not limited to the investment portfolio, electronic delivery channels and areas that primarily support the banking segment operations.  Therefore, these are included in the results of the Banking segment. Other indirect revenue and expenses related to general administrative areas are also included in the internal financial results reports of the Banking segment utilized by the CEO for analysis and are thus included for Banking segment reporting. The Mortgage segment utilizes funding sources from the Banking segment in order to fund mortgage loans that are ultimately sold on the secondary market. The Mortgage segment uses the proceeds from loan sales to repay obligations due to the Banking segment.

The following tables provides segment financial information for the three and six months ended June 30, 2018 and 2017 follows:

Minimum Capital Requirements

Banking And Thrift [Abstract]

Minimum capital requirements

Note (12)—Minimum capital requirements:

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

Under regulatory guidance for non-advanced approaches institutions, the Bank is required to maintain minimum amounts and ratios of common equity Tier I capital to risk-weighted assets. Additionally, under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. As of June 30, 2018 and December 31, 2017, the Bank and Company met all capital adequacy requirements to which it is subject. Also, as of June 30, 2018, the most recent notification from the Federal Deposit Insurance Corporation (“FDIC”), the Bank was well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category.

Beginning in 2016, an additional conservation buffer was added to the minimum requirements for capital adequacy purposes, subject to a three year phase-in period. As of June 30, 2018 and December 31, 2017, the buffer was 1.75 percent and 1.25 percent, respectively. The capital conservative buffer will be fully phased in January 1, 2019 at 2.5 percent.

Actual and required capital amounts and ratios are presented below at period-end:

Stock-Based Compensation

Note (13)—Stock-Based Compensation:

The Company granted shares of common stock and restricted stock units as a part of its initial public offering and compensation arrangements for the benefit of employees, executive officers, and directors. Restricted stock unit grants are subject to time-based vesting. The total number of restricted stock units granted represents the maximum number of restricted stock units eligible to vest based upon the service conditions set forth in the grant agreements.

Following the initial public offering, participants in the EBI Plans were given the option to elect conversion of their outstanding cash-settled EBI Units to stock-settled EBI Units. At June 30, 2018 and December 31, 2017, there were 29,172 and 67,470 units valued at $1,188 and $2,833, respectively, outstanding under the equity based incentive plans for employees who elected cash settlement of EBI units. Expense related to the cash settled EBI was $102 and $219 for the three and six months ended June 30, 2018, respectively, and $184 and $482 for the three and six months ended June 30, 2017, respectively.

The following table summarizes information about vested and unvested restricted stock units, excluding cash-settled EBI units discussed above, outstanding at June 30, 2018 and 2017:

	Six Months Ended June 30,

The compensation cost related to stock grants and vesting of restricted stock units, excluding cash-settled EBI units discussed above, was $1,861and $3,819 for the three and six months ended June 30, 2018, respectively, and $1,802 and $3,154 for the three and six months ended June 30, 2017, respectively. The current period included a one-time expense of $249 related to the modification of vesting terms of certain grants during the six months ended June 30, 2018.

As of June 30, 2018 and December 31, 2017, there were $14,061 and $12,950, respectively, of total unrecognized compensation cost related to nonvested restricted stock units (excluding cash-settled EBI units discussed above) which is expected to be recognized over a weighted-average period of 2.78years and 2.80 years, respectively.At June 30, 2018, there was $70 accrued in other liabilities related to dividends declared to be paid upon vesting and distribution of the underlying RSUs.

Employee Stock Purchase Plan:

In 2016, the Company adopted an employee stock purchase plan (“ESPP”) under which employees, through payroll deductions, are able to purchase shares of Company common stock. The purchase price is 95% of the lower of the market price on the first or last day of the offering period. The maximum number of shares issuable during any offering period is 200,000 shares, and a participant may not purchase more than 725 shares during any offering period (and, in any event, no more than $25,000 worth of common stock in any calendar year). There were 0 and 16,537 shares issued under the ESPP during the three and six months ended June 30, 2018, respectively. There were no such issuances during the three or six months ended June 30, 2017. As of June 30, 2018 and December 31, 2017, there were 2,444,428 shares and 2,460,965 shares, respectively, available for issuance under the ESPP.

Earnings Per Share

Earnings per share

Basic earnings per common share (“EPS”) excludes dilution and is computed by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the dilutive effect of additional potential common shares issuable under the restricted stock units granted but not yet vested and distributable. Diluted EPS is computed by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding for the year, plus an incremental number of common-equivalent shares computed using the treasury stock method.

Unvested share-based payment awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered to participate with common shareholders in undistributed earnings for purposes of computing EPS. Companies that have such participating securities, including FB Financial, are required to calculate basic and diluted EPS using the two-class method. Certain restricted stock awards granted by the Company include non-forfeitable dividend equivalents and are considered participating securities. Calculations of EPS under the two-class method (i) exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities and (ii) exclude from the denominator the dilutive impact of the participating securities.

The following is a summary of the basic and diluted earnings per common share calculation for each of the periods presented:

Recently Adopted Accounting Principles

Recently adopted accounting principles:

Except as set forth below, the Company did not adopt any new accounting policies that were not disclosed in the Company’s 2017 audited consolidated financial statements included on Form 10-K.

On January 1, 2018, the Company adopted the following newly issued accounting standards:

In May 2014, the FASB issued an update to Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”. The Company adopted this guidance on January 1, 2018 and all subsequent amendments to the ASU (collectively, “ASC 606”) which (i) creates a single framework for recognizing revenue from contracts with customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets, such as OREO.  The majority of the Company’s revenues come from interest income and other sources, including loans, leases, securities and derivatives that are outside the scope of ASC 606.  The Company’s services that fall within the scope of ASC 606 are presented within Noninterest income and are recognized as revenue as the Company satisfies its obligation to the customer.  Services within the scope of ASC 606 include deposit service charges on deposits, interchange income, investment services and trust income, and the sale of OREO, all within the Banking Segment.  The Company has evaluated the effect of this updated on these fee-based income streams and concluded that adoption did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded.

The following is a summary of the implementation considerations for the revenue streams that fall within the scope of Topic 606:

• Service charges on deposits, investment services and trust income, and interchange fees — Fees from these services are either transaction based, for which the performance obligations are satisfied when the individual transaction is processed, or set periodic service charges, for which the performance obligations are satisfied over the period the service is provided. Transaction based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on the Company's revenue recognition practice for these services.

• Gains on sales of other real estate — ASU 2014-09 creates Topic 610-20, under which a gain on sale should be recognized when a contract for sale exists and control of the asset has been transferred to the buyer. Topic 606 list several criteria which must exist to conclude that a contract for sale exists, including a determination that the institution will collect substantially all of the consideration to which it is entitled. This presents a key difference between the current and new guidance related to the recognition of the gain when the institution finances the sale of the property. Rather than basing recognition on the amount of the buyer's initial investment, which was the primary consideration under prior guidance, the analysis is now based on various factors including not only the loan to value, but also the credit quality of the borrower, the structure of the loan, and any other factors that may affect collectability. While these differences may affect the decision to recognize or defer gains on sales of other real estate in circumstances where the Company has financed the sale, these amounts have not been material to its financial statements.

In January 2016, the FASB released ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.” The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and adjust the fair value disclosures for financial instruments carried at amortized cost such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value such that these securities can be carried at cost less any impairment. Results for reporting periods beginning after January 1, 2018 are presented under this method while prior period disclosures are presented under legacy GAAP. On January 1, 2018, the Company recorded a net loss in beginning retained earnings of $109 in connection with this transition.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (Topic 230).” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. This adoption did not have an impact on our financial statements.

In May 2017, the FASB issued ASU 2017-09, “Stock Compensation - Scope of Modification Accounting (Topic 718): Scope of Modification Accounting.” The amendments in this ASU provide guidance on when changes to the terms or conditions of a share-based payment award are to be accounted for as modifications. Under ASU 2017-09, entities are not required to apply modification accounting to a share-based payment award when the award’s fair value, vesting conditions, and classification as an entity or a liability instrument remain the same after the change. ASU 2017-09 is effective for all entities beginning after December 15, 2017 including interim periods within the fiscal year. The adoption of this update on January 1, 2018 did not have a significant impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU make more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. There was no impact to the Company’s financial statements or disclosures as a result of this early adoption as of January 1, 2018.

Newly issued not yet effective accounting standards:

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The update will require lessees to recognize right-of-use assets and lease liabilities for all leases not considered short term leases. The provisions of the update also include (a) defining direct costs to only include those incremental costs that would not have been incurred if the lease had not been entered into, (b) circumstances under which the transfer contract in a sale-leaseback transaction should be accounted for as the sale of an asset by the seller-lessee and the purchase of an asset by the buyer-lessor, and (c) additional disclosure requirements. The provisions of this update become effective for interim and annual periods beginning after December 15, 2018. Management is currently evaluating the potential impact of this update.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as, the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will become effective for interim and annual periods beginning after December 15, 2019. Management is currently evaluating the potential impact of this update.

In March 2017, the FASB issued ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. The adoption of this update will not have an impact on the Company’s consolidated financial statements.
