NOTE 2 – ACCOUNTING STANDARDS UPDATES AND RECENTLY ADOPTED STANDARDS

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016‑02, “Leases.” Under the new guidance, leases classified as operating leases under previous GAAP must be recorded on the balance sheet. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use (“ROU”) asset representing its right to use the underlying asset for the lease term. In July 2018, the FASB issued ASU No. 2018‑10, “Codification Improvements to Topic 842, Leases and ASU No. 2018‑11, Leases (Topic 842): Targeted Improvements.”  ASU No. 2018‑10 provides improvements related to ASU No. 2016‑02 to increase stakeholders’ awareness of the amendments and to expedite the improvements. The amendments affect narrow aspects of the guidance issued in ASU No. 2016‑02. ASU No. 2018‑11 allows entities adopting ASU No. 2016‑02 to choose an additional (and optional) transition method, under which an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The amendments in these updates became effective for the Company on January 1, 2019. The impact of adoption was recording a lease liability of approximately $18.9 million in other liabilities on the Consolidated Balance Sheets, a ROU asset of approximately $14.5 million in premises and equipment, and a cumulative effect adjustment to retained earnings, net of tax, of approximately $373,000.

Recently Issued Accounting Pronouncements Not Yet Adopted

In May 2019, the FASB issued ASU No. 2019‑05, “Financial Instruments - Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016‑13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of Accounting Standards Codification (“ASC”) 326‑20 if the instruments are eligible for the fair value option under ASC 825‑10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. ASU 2019‑05 has the same effective date as ASU 2016‑13 (i.e., the first quarter of 2020). The Company does not expect to elect the fair value option, and therefore, ASU 2019‑05 is not expected to impact the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018‑13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” The amendments in this update modify the

7

disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The update is effective for interim and annual periods in fiscal years beginning after December 31, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for new disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The adoption will not have a material effect on the Company’s consolidated financial statements.

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.” This guidance shortens the premium amortization period for certain callable debt securities by requiring amortization to the earliest call date. The standard is effective for public companies for annual and interim periods beginning after December 15, 2020. The adoption of this update is not expected to have a material impact on Atlantic Capital’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which intends to simplify goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The update instead requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017‑04 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. Atlantic Capital does not expect the new guidance to have a material impact on its financial condition or results of operations.

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 an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016‑13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. ASU 2016‑13 is effective for public companies for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is implementing a software package supported by a third-party vendor. The Company’s CECL working group is meeting regularly with a CECL Management Group and the Company’s Board of Directors to discuss implementation progress and methodology selections. Progress has been made on life-of-loan loss calculations and on economic forecasting methods that will be utilized in the modeling process. The Company continues to refine its new methodology leading up to the adoption of the ASU and will continue to evaluate the impact of the adoption on the Company’s consolidated financial statements and disclosures.

NOTE 3 – ACQUISITIONS AND DIVESTITURES

Discontinued Operations

On April 5, 2019, the Bank completed the sale of all 14 of its bank branches located in Tennessee and northwest Georgia, including its mortgage banking business, to FirstBank (the “Branch Sale”). FirstBank assumed deposits and customer repurchase agreements of approximately $598 million and purchased approximately $385 million in loans. FirstBank paid a deposit premium equal to 6.25% of the balance of assumed deposits, less a discount of 0.68% of purchased loans.

The income and expenses related to these branches for the three and nine months ended September 30, 2019 and 2018 are included in discontinued operations and prior period financial information has been retrospectively adjusted for the impact of discontinued operations.

Management evaluates securities for other-than-temporary impairment on a quarterly basis. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, among other factors. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and internal and external analyst reviews.

At September 30, 2019, there were 77 available-for-sale securities and 7 held-to-maturity securities that were in an unrealized loss position. Atlantic Capital does not intend to sell and does not believe it will be required to sell securities in an unrealized loss position prior to the recovery of their amortized cost basis. Unrealized losses at September 30, 2019 and December 31, 2018 were attributable to changes in interest rates. No impairment charges on securities were recognized during the three or nine months ended September 30, 2019 or 2018.

Realized gains and losses are derived using the specific identification method for determining the cost of securities sold. The following table summarizes securities sales activity for the three and nine months ended September 30, 2019 and 2018.

	Three Months Ended September 30,				Nine Months Ended September 30,

Investment securities with a carrying value of $32.3 million and $65.3 million were pledged to secure public funds and other borrowings at September 30, 2019 and December 31, 2018, respectively.

12

As of September 30, 2019 and December 31, 2018, Atlantic Capital had investments with a carrying value of $4.4 million and $4.4 million, respectively, in Small Business Investment Companies (“SBICs”) where Atlantic Capital is the limited partner. These investments are included in other assets on the Consolidated Balance Sheets. During the nine months ended September 30, 2019 and 2018, the Company recorded impairments in the amounts of $26,000 and $228,000, respectively, on these SBICs. The impairments resulted from deterioration in the credit quality of one of the SBICs and their inability to pay distributions until their financial position improves. There have been no upward adjustments, cumulatively or year-to-date, on these investments.

NOTE 6 – LOANS AND ALLOWANCE FOR LOAN LOSSES

At December 31, 2018, PCI loans were designated as held for sale for the Branch Sale. The following table presents changes in the value of the accretable yield for acquired loans accounted for under ASC 310‑30 for the three and nine months ended September 30, 2019 and 2018.

	For the Three Months Ended				For the Nine Months Ended

Other changes, net		—		96		—		542
Balance at end of period	$	—	$	2,433	$	—	$	2,433

In addition to the accretable yield on PCI loans, the fair value adjustments on purchased loans outside the scope of ASC 310‑30 are also accreted to interest income over the life of the loans. At September 30, 2019, the remaining accretable fair value discount on loans acquired through a business combination and not accounted for under ASC 310‑30 was $324,000 compared to $3.6 million at December 31, 2018.

The allowance for loan losses represents management’s estimate of probable incurred losses in the loan portfolio as of the end of the period. It is comprised of specific reserves for impaired loans and a general allowance for pools of loans with similar characteristics not individually evaluated. The allowance is regularly evaluated to maintain an adequate level to absorb probable current inherent losses in the loan portfolio. Factors contributing to the determination of the allowance include the credit worthiness of the borrower, changes in the value of pledged collateral, and general economic conditions. Most loan commitments rated substandard or worse are specifically reviewed for loss potential. For loans deemed to be impaired, a specific allocation is assigned based on the losses expected to be realized from those loans.

The following table presents the balance and activity in the allowance for loan losses by portfolio segment for the three and nine months ended September 30, 2019 and 2018.

Atlantic Capital evaluates loans in accordance with ASC 310‑40, Troubled Debt Restructurings by Creditors. TDRs are loans in which Atlantic Capital has modified the terms or granted an economic concession to a borrower who is experiencing financial difficulties. These modifications may include interest rate reductions, term extensions and other concessions intended to minimize losses.

As of September 30, 2019, and December 31, 2018, the Company had a recorded investment in TDRs of $12.8 million and $8.2 million, respectively. The Company had commitments to lend additional funds of $3,000 and $28,000 on loans modified as TDRs, as of September 30, 2019 and December 31, 2018, respectively. During the three months ended September 30, 2019, the Company restructured via bankruptcy one commercial real estate SBA loan, resulting in its

16

reclassification as a TDR. For the nine months ended September 30, 2019, restructurings included modifications such as payment deferrals and interest only forbearance.

Loans, by portfolio class, modified as TDRs during the three and nine months ended September 30, 2019 are as follows.

		Pre-Modification			Post-Modification
		Outstanding			Outstanding

The Company did not forgive any principal on TDRs during the three and nine month periods ended September 30, 2019 and 2018, and there were no subsequent defaults of previously identified TDRs.

Atlantic Capital individually rates loans based on internal credit risk ratings using numerous factors, including thorough analysis of historical and expected cash flows, consumer credit risk scores (FICO scores), rating agency information, LTV ratios, collateral, collection experience, and other internal metrics. Atlantic Capital uses a dual rating system. The likelihood of default of a credit transaction is graded in the Obligor Rating. The risk of loss given default is graded in the Facility Rating. The Obligor Rating is determined through credit analysis. Facility Ratings are used to describe the value to the Company that the collateral represents. Facility Ratings are based on the collateral package or market expectations regarding the value and liquidity of the collateral. Ratings are generally reviewed at least annually or more frequently if there is a material change in creditworthiness. Exceptions to this policy may include well collateralized term loans and loans to individuals with limited exposure or complexity.

Atlantic Capital uses the following definitions for risk ratings:

Pass: Loans that are analyzed individually as part of the above described process and that do not meet the criteria of special mention, substandard or doubtful.

Special Mention: Loans classified as special mention have a potential weakness that requires 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 classified 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 classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

NOTE 8 – SERVICING ASSETS

SBA Servicing Assets

SBA servicing assets are initially recorded at fair value. Subsequently, Atlantic Capital accounts for SBA servicing assets using the amortization method and they are included in other intangibles, net on the Consolidated Balance Sheets. As of September 30, 2019 and December 31, 2018, the balance of SBA loans sold and serviced by Atlantic Capital totaled $184.6 million and $161.5 million, respectively.

Changes in the balance of servicing assets for the three and nine months ended September 30, 2019 and 2018 are presented in the following table.

	Three Months Ended September 30,				Nine Months Ended September 30,
SBA Loan Servicing Assets	2019		2018		2019		2018
	(in thousands)				(in thousands)

At September 30, 2019 and December 31, 2018, the sensitivity of the fair value of the SBA loan servicing assets to immediate changes in key economic assumptions are presented in the table below.

Sensitivity of the SBA Servicing Assets	September 30, 2019			December 31, 2018
	(dollars in thousands)
Fair value of retained servicing assets	$	3,029		$	2,630
Weighted average life		3.90 years			4.83 years
Prepayment speed:		14.71	%		11.92	%
Decline in fair value due to a 10% adverse change	$	(160)		$	(131)
Decline in fair value due to a 20% adverse change	$	(271)		$	(223)
Weighted average discount rate		14.01	%		14.42	%
Decline in fair value due to a 100 bps adverse change	$	(107)		$	(101)
Decline in fair value due to a 200 bps adverse change	$	(169)		$	(165)

The above sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on valuation assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities.

TriNet Servicing Assets

Changes in the balance of TriNet servicing assets for the three and nine months ended September 30, 2019 and 2018 are presented in the following table.

The above sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on valuation assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities.

NOTE 10 – EARNINGS PER COMMON SHARE

Basic earnings per share amounts are computed by dividing net income by the weighted average number of shares of common stock outstanding.

Diluted earnings per share amounts are computed by dividing net income by the weighted average number of shares of common stock outstanding and the dilutive effects of the shares awarded under the stock option plan, based on the treasury stock method using an average fair market value of the stock during the respective periods.

Stock options outstanding of 150 at September 30, 2019 and 244 at September 30, 2018 have not been included in diluted earnings per share because to do so would have been anti-dilutive for the periods presented. These awards were considered anti-dilutive because the exercise price of the award was higher than the market value of the shares.

The Amended and Restated Articles of Incorporation of Atlantic Capital authorize Atlantic Capital to issue 110,000,000 shares of capital stock, of which 10,000,000 shares are designated as preferred stock, no par value per share, and 100,000,000 shares are designated as common stock, no par value per share. At September 30, 2019, 22,193,761 shares of common stock were issued and outstanding. At December 31, 2018, 25,290,419 shares of common stock were issued and outstanding.

The primary source of funds available to Atlantic Capital is payments of dividends from the Bank. The Bank paid dividends totaling $10.0 million and $36.5 million to Atlantic Capital during the three and nine months ended September 30, 2019. No dividends were paid by the Bank during the three or nine months ended September 30, 2018. During the fourth quarter of 2018, the Bank paid a dividend totaling $30.0 million. Banking laws and other regulations limit the amount of dividends a bank subsidiary may pay without prior regulatory approval. Additionally, Atlantic Capital’s ability to pay dividends to its shareholders will depend on the ability of the Bank to pay dividends to Atlantic Capital. The Bank is subject to regulatory restrictions on the payment of cash dividends, which generally may be paid only from current earnings.

On November 14, 2018, the Board of Directors authorized a stock repurchase program pursuant to which the Company may purchase up to $85 million of its issued and outstanding common stock. The timing and amounts of any repurchases depend on certain factors, including but not limited to market conditions and prices, available funds and alternative uses of capital. The stock repurchase program may be carried out through open-market purchases, block trades, negotiated private transactions and pursuant to a trading plan that was adopted in accordance with Rule 10b‑18 and Rule 10b5‑1 under the Securities Exchange Act of 1934. Atlantic Capital repurchased 1,164,063 and 3,242,579 shares during the three and nine months ended September 30, 2019 for a total of $20.1 million and $56.7 million, respectively. Since the announcement of the $85.0 million buyback program in November of 2018, Atlantic Capital has repurchased 4.1 million shares totaling $70.9 million.

NOTE 11 – DERIVATIVES AND HEDGING

Risk Management

Atlantic Capital’s objectives in using interest rate derivatives are to add stability to net interest revenue and to manage its exposure to interest rate movements. To accomplish these objectives, Atlantic Capital primarily uses interest rate swaps as part of its interest rate risk management strategy.

Cash Flow Hedges

At September 30, 2019, Atlantic Capital’s interest rate swaps designated as cash flow hedges involve the payment of floating-rate amounts to a counterparty in exchange for receiving fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. At September 30, 2019 and December 31, 2018, Atlantic Capital had interest rate swaps designated as cash flow hedges with aggregate notional amounts of $175.0 million and $100.0 million, respectively.

No hedge ineffectiveness gains or losses were recognized on active cash flow hedges for the three and nine months ended September 30, 2019 and 2018. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Atlantic Capital expects that approximately $230,000 will be reclassified as an increase to loan interest income over the next twelve months related to these cash flow hedges.

Customer Swaps

Atlantic Capital also enters into derivative contracts, which consist of interest rate swaps, to facilitate the needs of customers desiring to manage interest rate risk. These swaps are not designated as accounting hedges under ASC 815, Derivatives and Hedging. To economically hedge the interest rate risk associated with offering this product, Atlantic Capital simultaneously enters into derivative contracts with third parties to offset the customer contracts, such that Atlantic Capital minimizes its net risk exposure resulting from such transactions. The derivative contracts are structured such that the notional amounts reduce over time to generally match the expected amortization of the underlying loans. These derivatives are not speculative and arise from a service provided to clients.

Atlantic Capital’s derivative instruments are recorded at fair value in other assets and accrued interest receivable and other liabilities and accrued interest payable in the Consolidated Balance Sheets. The changes in the fair value of the derivative instruments are recognized in derivatives income in the Consolidated Statements of Income. At September 30, 2019 and December 31, 2018, Atlantic Capital had interest rate swaps related to this program with an aggregate notional amount of $92.5 million and $109.5 million, respectively.

Atlantic Capital acquired a loan level hedging program, which First Security Group, Inc. (“First Security”) utilized to accommodate clients preferring a fixed rate loan. The loan documents include an addendum with a zero premium collar. The zero premium collar is a cap and a floor at the same interest rate, resulting in a fixed rate to the borrower. To hedge this embedded option, First Security entered into a dealer facing trade exactly mirroring the terms in the loan addendum. At September 30, 2019 and December 31, 2018, Atlantic Capital had interest rate swaps related to this program with an aggregate notional amount of $150.4 million and $166.8 million, respectively.

Counterparty Credit Risk

As a result of its derivative contracts, Atlantic Capital is exposed to credit risk. Specifically approved counterparties and exposure limits are defined. Quarterly, the customer derivative contracts and related counterparties are evaluated for credit risk and an adjustment is made to the contract’s fair value. This adjustment is recognized in the Consolidated Statements of Income.

Most derivative contracts with clients are secured by collateral. Additionally, in accordance with the interest rate agreements with derivatives dealers, Atlantic Capital may be required to post margin to these counterparties. At

24

September 30, 2019 and December 31, 2018, Atlantic Capital had minimum collateral posting thresholds with certain of its derivative counterparties and posted collateral of $14.3. million and $5.1 million, respectively, against its obligations under these agreements. Cash collateral related to derivative contracts is recorded in other assets in the Consolidated Balance Sheets.

Atlantic Capital has master netting agreements with the derivatives dealers with which it does business, but reflects gross assets and liabilities on the Consolidated Balance Sheets.

In conjunction with the FASB’s fair value measurement guidance, management made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting arrangements on a net basis.

To accommodate clients, Atlantic Capital occasionally enters into credit risk participation agreements with counterparty banks to accept a portion of the credit risk related to interest rate swaps. This allows clients to execute an interest rate swap with one bank while allowing for distribution of the credit risk among participating members. Credit risk participation agreements arise when Atlantic Capital contracts with other financial institutions, as a guarantor, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third party default on the underlying swap. At September 30, 2019 and December 31, 2018, Atlantic Capital had credit risk participation agreements with a notional amount of $8.1 million and $9.5 million, respectively.

The following table reflects the estimated fair value positions of derivative contracts and credit risk participation agreements as of September 30, 2019 and December 31, 2018:

NOTE 12 – OTHER BORROWINGS AND LONG TERM DEBT

There were no Federal Home Loan Bank borrowings outstanding as of December 31, 2018. Federal Home Loan Bank borrowings as of September 30, 2019 are as follows:

	September 30, 2019
	Balance		Interest Rate
	(in thousands)
FHLB short-term borrowings:
Fixed rate advance maturing October 7, 2019	$	45,000	2.08	%
Fixed rate advance maturing October 8, 2019		31,000	2.08
Total	$	76,000

Interest expense for FHLB borrowings for the three and nine months ended September 30, 2019 was $390,000 and $660,000, respectively. Interest expense for FHLB borrowings for the three and nine months ended September 30, 2018 was $637,000 and $1.9 million, respectively.

At September 30, 2019, the Company had available line of credit commitments with the FHLB totaling $716.5 million, with $76.0 million in outstanding FHLB advances. However, based on actual collateral pledged, $163.7 million was available. At September 30, 2019, the Company had an available line of credit based on the collateral available of $367.4 million with the Federal Reserve Bank of Atlanta. Interest expense on federal funds purchased for the three and nine months ended September 30, 2019 totaled $99,000 and $385,000, respectively, and $77,000 and $244,000 for the three and nine months ended September 30, 2018, respectively.

On September 28, 2015, Atlantic Capital issued subordinated notes (the “Notes”) totaling $50.0 million in aggregate principal amount. The Notes are due September 30, 2025 and bear a fixed rate of interest of 6.25% per year until

26

September 29, 2020. From September 30, 2020 to the maturity date, the interest rate will be a floating rate equal to the three-month LIBOR plus 468 basis points. The Notes were priced at 100% of their par value. The Notes qualify as Tier 2 regulatory capital.

Subordinated debt is summarized as follows:

	September 30, 2019		December 31, 2018
	(in thousands)
Floating rate 10 year capital securities, with interest paid semi-annually at an annual fixed rate of 6.25% until September 30, 2020	$	50,000	$	50,000

All subordinated debt outstanding at September 30, 2019 matures after more than five years.

NOTE 13 – SHARE-BASED COMPENSATION

Atlantic Capital sponsors a stock incentive plan for the benefit of directors and employees. Under the Company’s 2015 Stock Incentive Plan (as amended and restated effective May 16, 2018), there were approximately 4,525,000 shares reserved for issuance to directors and employees. The Compensation Committee has the authority to grant the following: an incentive or nonqualified option; a restricted stock award (including a restricted stock award or a restricted unit award); a performance award (including a performance share award or a performance unit award); a phantom stock award; a dividend equivalent award; or any other award granted under the plan.

As of September 30, 2019, approximately 3,345,000 additional awards were available to be granted under the plan. Stock options are granted at a price which is no less than the fair market value of a share of Atlantic Capital common stock on the grant date. Stock options generally vest over three years and expire after ten years.

The Company estimates the fair value of its options awards using the Black-Scholes option pricing model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The table below summarizes the assumptions used to calculate the fair value of options granted/modified during the nine months ended September 30, 2019 and 2018:

	For the nine months ended September 30,
	2019		2018
Risk‑free interest rate	2.27	%	1.66	%
Expected term in years	1.73-1.82		0.25
Expected stock price volatility	26.8	%	24.2	%

⁽¹⁾ During the nine months ended September 30, 2019, the Company modified options for 12,500 shares. The modifications are included as shares granted/modified and as shares forfeited in this table.

Atlantic Capital recognized compensation expense relating to stock options of $18,000 and $151,000 for the three and nine months ended September 30, 2019, respectively, and $70,000 and $167,000 for the three and nine months ended September 30, 2018, respectively. Using the Black-Scholes pricing model, the amount of compensation expense was determined based on the fair value of the options at the time of grant, multiplied by the number of options granted that were expected to vest, which was then amortized over the vesting period. In April 2018, the Company granted performance share awards to members of executive management under Atlantic Capital’s Long Term Incentive Plan (“LTIP”). The Company also granted restricted stock awards to certain employees and directors in 2019 under the 2015 Stock Incentive Plan.

The following table represents restricted stock and performance share award activity for the nine months ended September 30, 2019:

		Weighted Average Grant-
	Shares	Date Fair Value
Outstanding, December 31, 2018	272,695	$	18.09
Granted/modified(1)	158,593		19.19
Vested	(68,198)		16.54
Forfeited(1)	(67,663)		18.34
Outstanding, September 30, 2019	295,427	$	18.97

⁽¹⁾ During the nine months ended September 30, 2019, the Company modified 4,719 restricted stock awards. The modifications are included as shares granted/modified and as shares forfeited in this table.

Compensation expense for restricted stock is based on the fair value of restricted stock awards at the time of grant, which is equal to the value of Atlantic Capital’s common stock on the date of grant. Compensation expense for performance share awards is based on the fair value of Atlantic Capital’s stock at the grant date adjusted for market conditions, as well as the subsequent achievement of performance conditions over the vesting period. The value of restricted stock and performance share grants that are expected to vest is amortized into expense over the vesting period. For the three months ended September 30, 2019 and 2018, compensation expense of $454,000 and $444,000, respectively, was recognized related to restricted stock and performance share awards. For the nine months ended September 30, 2019 and 2018, compensation expense of $1.2 million and $1.3 million respectively, was recognized related to restricted stock and performance share awards.

As of September 30, 2019, there was $2.6 million of unrecognized compensation cost related to restricted stock awards granted under the plan. That cost is expected to be recognized over a weighted-average period of 2.27 years.

During the nine months ended September 30, 2019, the Company modified options for 12,500 shares and 4,719 restricted stock awards to two individuals. The modifications allowed for the immediate vesting of the awards upon retirement, as

28

defined in the 2015 Stock Incentive Plan. The total incremental cost resulting from the modifications was $31,000 for the nine months ended September 30, 2019.

NOTE 14 – FAIR VALUE MEASUREMENTS

Atlantic Capital follows the guidance pursuant to ASC 820‑10, Fair Value Measurements and Disclosures. This guidance defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. This issuance applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances. Atlantic Capital measures its investment securities and interest rate derivative assets and liabilities at fair value on a recurring basis. Fair value is used on a nonrecurring basis either when assets are evaluated for impairment or for disclosure purposes. Atlantic Capital measures its servicing assets, goodwill, intangible assets, SBIC investments, loans held for sale, impaired loans and other real estate owned at fair value on a nonrecurring basis if necessary.

The guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement and defines fair value as the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, this guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Atlantic Capital applied the following fair value hierarchy:

Level 1 – Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts.

Level 2 – Assets or liabilities valued based on observable market data for similar instruments.

Level 3 – Assets or liabilities for which significant valuation assumptions are not readily observable in the market, instruments valued based on the best available data, some of which is internally-developed, and risk premiums that a market participant would require.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement. There were no transfers between Level 1 and Level 2 or Level 2 and Level 3 during the three or nine months ended September 30, 2019 and 2018.

Atlantic Capital records investment securities available-for-sale at fair value on a recurring basis. Investment securities classified as available-for-sale are reported at fair value utilizing Level 2 inputs. For these securities, Atlantic Capital obtains fair value measurements from an independent pricing service. In estimating the fair values for investment securities, Atlantic Capital believes that independent third-party market prices are the best evidence of an exit price. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the Treasury Department yield curve, trade execution data, market consensus prepayment speeds, credit information and the securities’ terms and conditions, among other things.

Derivative instruments are primarily transacted as over-the-counter trades and priced with observable market assumptions. Ongoing measurements include observable market assumptions with appropriate valuation adjustments for liquidity and for credit risk of counterparties and Atlantic Capital’s own credit. For these instruments, Atlantic Capital obtains fair value measurements from an independent pricing service. The fair value measurements consider factors such as the likelihood of default by Atlantic Capital and its counterparties, total exposure and remaining maturities in determining the appropriate fair value adjustments to record. Generally, the expected loss of each client counterparty is estimated using Atlantic Capital’s internal risk rating system. For financial institution counterparties that are rated by national rating agencies, those

29

ratings are used in determining the credit risk. This approach used to estimate exposures to counterparties is also used by Atlantic Capital to estimate its own credit risk on derivative liability positions.

Impaired Loans	$	—	$	—	$	1,836	$	1,836

Level 3 loans consist of impaired loans which have been partially charged-off or have specific valuation allowances. The fair value of Level 3 assets is estimated based on the underlying collateral value. For loans which the cash proceeds from the sale of the underlying collateral is the expected source of repayment, the fair value of these loans was derived from internal estimates of the underlying collateral incorporating market data, including third party appraisals or evaluations, when available. Appraised values may be discounted based on management’s assessment of the level of inactivity in the real estate market and other markets for the underlying collateral, changes in market conditions from the time of the valuation, and other information that in management’s judgment may affect the value. Impaired loans are evaluated on at least a quarterly basis and adjusted accordingly.

Assets and Liabilities Not Measured at Fair Value

For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate, are assumed to have a fair value that approximates the reported book value, after taking into consideration any applicable credit risk. If no market quotes are available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument. For loans held for investment, fair value is measured using the exit price notion. For off-balance sheet derivative instruments, fair value is estimated as the amount that Atlantic Capital would receive or pay to terminate the contracts at the reporting date, taking into account the current unrealized gains or losses on open contracts.

The short maturity of Atlantic Capital’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest-bearing deposits in other banks, other short-term investments, and FHLB stock. The fair value of securities equals quoted market prices, if available.  If a quoted market price is not available, fair value is estimated used quoted market prices for similar securities or dealer quotes. Due to the short-term settlement of accrued interest receivable and payable, the carrying amount closely approximates fair value.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect the premium or discount on any particular financial instrument that could result from the sale of Atlantic Capital’s entire holdings. Because no ready market exists for a significant portion of Atlantic Capital’s financial instruments, fair value estimates are based on many judgments. These estimates are subjective in nature, involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Off-balance sheet financial instruments (commitments to extend credit and standby letters of credit) are generally short-term and at variable rates. Therefore, both the carrying amount and the estimated fair value associated with these instruments are immaterial.

NOTE 15 – COMMITMENTS AND CONTINGENCIES

Atlantic Capital is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and letters of credit, most of which are standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the Consolidated Balance Sheets. The contract amounts of these instruments reflect the extent of involvement Atlantic Capital has in particular classes of financial instruments.

Standby letters of credit are written conditional commitments issued by Atlantic Capital to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. Most letters of credit expire in less than one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Atlantic Capital’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. Atlantic Capital uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Atlantic Capital’s maximum exposure to credit risk for unfunded loan commitments and standby letters of credit at September 30, 2019 and December 31, 2018 was as follows:

	September 30, 2019		December 31, 2018
	(in thousands)
Financial Instruments whose contract amount represents credit risk:
Commitments to extend credit	$	679,732	$	715,591
Standby letters of credit		7,563		15,650
	$	687,295	$	731,241
Minimum lease payments	$	16,669	$	22,014

The Company also had commitments related to investments in SBICs totaling $2.9 million and $3.2 million at September 30, 2019 and December 31, 2018, respectively.

From time to time, Atlantic Capital, in the normal course of business, is subject to various pending and threatened lawsuits in which claims for monetary damages are asserted. Although it is not possible to predict the outcome of these lawsuits, or the range of any possible loss, management, after consultation with legal counsel, does not anticipate that the ultimate aggregate liability, if any, arising from these lawsuits will have a material adverse effect on Atlantic Capital’s financial position or results of operations.

NOTE 16 – REVENUE RECOGNITION

On January 1, 2018, the Company adopted ASU No. 2014‑09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent ASUs that modified Topic 606. As stated in Note 2, Accounting Standards Updates and Recently Adopted Standards, the implementation of the new standard did not result in any significant changes to the Company’s methodology of recognizing revenue; as such, the Company recorded an immaterial cumulative effect adjustment to first quarter 2018 opening retained earnings. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historic accounting under Topic 605.

Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with financial guarantees and derivatives are not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as service charges on deposit accounts and trust and asset management income. However, the recognition of these revenue streams did not change

33

significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams within the scope of Topic 606 are discussed below.

Service Charges on Deposit Accounts

Service charges represent general service fees for monthly account maintenance and activity, or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed, such as a wire transfer or ATM withdrawal. Payment for such performance obligations are generally received at the time the performance obligations are satisfied. The following table presents service charges by type of service provided for the three and nine months ended September 30, 2019 and 2018:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2019		2018		2019		2018

Service charges - discontinued operations		—		474		527		1,439
Total service charges	$	925	$	1,278	$	3,116	$	3,778

Trust and Asset Management

Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. During the second quarter of 2018, Atlantic Capital sold its trust business, Southeastern Trust Company. The following table presents trust income by type of service provided for the three and nine months ended September 30, 2018:

	For the Three Months Ended September 30,					For the Nine Months Ended September 30,
	2019		2018		2019		2018
Personal trust and agency accounts	$	—	$	—	$	—	$	616

Custody and safekeeping accounts		—		—		—		26
Other		—		—		—		46
	$	—	$	—	$	—	$	1,025

Other

Other noninterest income consists of other recurring revenue streams such as check printing income, safety deposit box rental fees, and other miscellaneous revenue streams. Check printing income is recognized ratably over the contract period

34

as the Company satisfies its performance obligation to sell a specific number of check packages. Safe deposit box rental fees are charged to the customer annually and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation.

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of September 30, 2019 and December 31, 2018, the Company did not have any significant contract balances.

NOTE 17 – LEASES

A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016‑02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842. For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee.

Operating leases in which the Company is the lessee are recorded as operating lease ROU assets and operating lease liabilities, included in premises and equipment and other liabilities, respectively, on the Consolidated Balance Sheets. The Company does not currently have any significant finance leases in which it is the lessee.

Operating lease ROU assets represent the Company’s right to use an underlying asset during the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents the Company’s incremental borrowing rate at the lease commencement date. ROU assets are further adjusted for lease incentives. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in net occupancy expense in the Consolidated Statements of Income.

The Company’s leases relate primarily to office space and bank branches with remaining lease terms of generally 1 to 12 years. Certain lease arrangements contain extension options which typically range from 5 to 10 years at the then fair market rental rates. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. Portions of certain properties are subleased for terms extending through 2024. As of September 30, 2019, operating lease ROU assets and liabilities were $9.9 million and $13.9 million, respectively. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the Consolidated Balance Sheets. Additionally, the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component.

The table below summarizes the Company’s net lease cost:

	Three Months Ended		Nine Months Ended
	September 30, 2019		September 30, 2019

On April 5, 2019, Atlantic Capital completed the sale to FirstBank of its Tennessee and northwest Georgia banking operations, including 14 branches. Eight of these properties were owned by Atlantic Capital and nine were leased. The Company’s ROU asset and lease liability were reduced during the second quarter of 2019 by $3.6 million and $4.1 million, respectively, as a result of this divestiture.

These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “would,” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates, and projections about our industry, management’s beliefs, and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you 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. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.

The following risks, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements:

· costs associated with our growth and hiring initiatives in the Atlanta market area;

· risks associated with increased geographic concentration, borrower concentration and concentration in commercial real estate and commercial and industrial loans resulting from our exit of the Tennessee and northwest Georgia markets and our strategic realignment;

· our strategic decision to increase our focus on SBA and franchise lending may expose us to additional risks associated with these types of lending, including industry concentration risks, our ability to sell the guaranteed portion of SBA loans, the impact of negative economic conditions on small businesses’ ability to repay the non-guaranteed portions of SBA loans, and changes to applicable federal regulations;

· risks associated with our ability to manage the planned growth of our payment processing business, including evolving regulations, security risks, and unforeseen increases in transaction volume resulting from changes in our customers’ businesses and changes in the competitive landscape for payment processing;  

· changes in asset quality and credit risk;

· the cost and availability of capital;

· customer acceptance of our products and services;

· customer borrowing, repayment, investment and deposit practices;

· the introduction, withdrawal, success and timing of business initiatives;

· the impact, extent, and timing of technological changes;

37

· severe catastrophic events in our geographic area;

· a weakening of the economies in which we conduct operations may adversely affect our operating results;

· the U.S. legal and regulatory framework could adversely affect the operating results of the Company;

· the interest rate environment may compress margins and adversely affect net interest income;

· our ability to anticipate or respond to interest rate changes correctly and manage interest rate risk presented through unanticipated changes in our interest rate risk position and/or short- and long-term interest rates;

· changes in trade, monetary and fiscal policies of various governmental bodies and central banks could affect the economic environment in which we operate;

· our ability to determine accurate values of certain assets and liabilities;

· adverse developments in securities, public debt, and capital markets, including changes in market liquidity and volatility;

· unanticipated changes in our liquidity position, including but not limited to our ability to enter the financial markets to manage and respond to any changes to our liquidity position;

· the impact of the transition from LIBOR and our ability to adequately manage such transition;

· adequacy of our risk management program;

· increased competitive pressure due to consolidation in the financial services industry;

· risks related to security breaches, cybersecurity attacks, and other significant disruptions in our information technology systems; and

· other risks and factors identified in our Annual Report on Form 10‑K as filed with the Securities and Exchange Commission on March 14, 2019 (the “Annual Report”) in Part I, Item 1A under the heading “Risk Factors.”

CRITICAL ACCOUNTING POLICIES

The accounting and reporting policies of Atlantic Capital are in accordance with GAAP and conform to general practices within the banking industry. Atlantic Capital’s financial position and results of operations are affected by management’s application of accounting policies, including judgments made to arrive at the carrying value of assets and liabilities and amounts reported for revenues, expenses and related disclosures. Different assumptions in the application of these policies could result in material changes in Atlantic Capital’s consolidated financial position and/or consolidated results of operations. The more critical accounting and reporting policies include Atlantic Capital’s accounting for the allowance for loan losses, fair value measurements, and income tax related items. Significant accounting policies are discussed in the Notes to Consolidated Financial Statements within Atlantic Capital’s Annual Report on Form 10‑K.

Non-GAAP Financial Measures.

This Form 10‑Q contains non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measures to GAAP financial measures. Atlantic Capital management uses non-GAAP financial measures, including: (i) taxable equivalent interest income; (ii) taxable equivalent net interest income; (iii) taxable equivalent net interest margin; (iv) taxable equivalent net interest income from continuing operations; (v) taxable equivalent net interest margin from continuing operations (vi) net interest income after provision for loan losses-taxable equivalent; (vii) income before income taxes-taxable equivalent; and (viii) income tax expense-taxable

38

equivalent. Management uses these non-GAAP financial measures because it believes they provide a greater understanding of ongoing performance and operations, enhance comparability with prior periods, and provide users of our financial information with a meaningful measure for assessing our financial results and credit trends. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as an alternative to any measure of performance or financial condition as determined in accordance with GAAP. In addition, non-GAAP financial measures may not be comparable to similarly titled non-GAAP financial measures presented by other companies. Investors should consider Atlantic Capital’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company. A reconciliation of these non-GAAP financial measures to GAAP financial measures is included in Table 1.

EXECUTIVE OVERVIEW AND EARNINGS SUMMARY

On April 5, 2019, the Bank completed the previously disclosed sale of all 14 of its bank branches located in Tennessee and northwest Georgia, including its mortgage banking business, to FirstBank (the “Branch Sale”). In connection with the Branch Sale, FirstBank assumed deposits and customer repurchase agreements of approximately $598 million and purchased approximately $385 million in loans. FirstBank paid a deposit premium equal to 6.25% of the balance of assumed deposits, less a discount of 0.68% of purchased loans. The income and expenses related to these branches are included in discontinued operations and prior period financial information has been retrospectively adjusted for the impact of discontinued operations. Net income from discontinued operations for the nine months ended September 30, 2019 included a gain on sale of branches of $34.5 million and divestiture expenses of $5.1 million.

Atlantic Capital reported net income from continuing operations of $7.6 million for the third quarter of 2019 compared to net income from continuing operations of $7.0 million for the third quarter of 2018. Diluted income per common share from continuing operations was $0.33 for the third quarter of 2019, compared to $0.27 for the same period in 2018.

For the nine months ended September 30, 2019, Atlantic Capital reported net income from continuing operations of $21.0 million. This compared to net income from continuing operations of $20.6 million for the nine months ended September 30, 2018. Diluted income per common share from continuing operations was $0.88 for the nine months ended September 30, 2019 compared to $0.79 for the same period in 2018.

The increase in net income from continuing operations for the three months ended September 30, 2019, compared to the same period in 2018, was primarily attributable to a $694,000, or 4%, increase in taxable equivalent net interest income from continuing operations and a $432,000 or 51% decrease in the provision for loan losses from continuing operations, partially offset by an $805,000, or 7%, increase in noninterest expense from continuing operations.

The increase in net income from continuing operations for the nine months ended September 30, 2019, compared to the same period in 2018, was primarily attributable to a $5.1 million, or 9%, increase in taxable equivalent net interest income from continuing operations, partially offset by a $1.8 million, or 19%, decrease in noninterest income from continuing operations and a $1.9 million, or 5%, increase in noninterest expense from continuing operations.

Taxable equivalent net interest income from continuing operations was $20.1 million for the third quarter of 2019, compared to $19.4 million for the third quarter of 2018. Taxable equivalent net interest margin from continuing operations increased to 3.52% for the three months ended September 30, 2019 from 3.48% for the three months ended September 30, 2018. For the nine months ended September 30, 2019, taxable equivalent net interest income from continuing operations was $60.6 million compared to $55.5 million for the same period of 2018. Taxable equivalent net interest margin from continuing operations increased to 3.66% for the nine months ended September 30, 2019 from 3.46% for the nine months ended September 30, 2018. The margin increase for the three and nine months ended September 30, 2019 compared to the prior year was primarily due to increases in the Federal Funds rate.

Provision for loan losses for the quarter ended September 30, 2019 totaled $413,000, a decrease of $432,000 from the quarter ended September 30, 2018. The decrease was primarily related to a  decrease in modeled loss rates and a change in loan mix when compared to the prior period. For the nine months ended September 30, 2019, Atlantic Capital’s provision for loan losses was $1.9 million compared to a provision of $1.4 for the first nine months of 2018. The increase was

39

primarily due to higher levels of net charge-offs for the nine months ended September 30, 2019 compared to the first nine months of 2018.

Noninterest income from continuing operations increased $514,000, or 23%, to $2.8 million from the third quarter of 2018. The increase was primarily due to the $253,000 gain on sale of available-for-sale securities and an increase of $268,000, or 30%, in income from SBA lending activities during the third quarter of 2019. Also contributing to the increase was an increase in gain on sales of other assets of $82,000, or 141%, in the third quarter of 2019. This was offset by a decrease in derivatives income of $313,000 in the third quarter of 2019.

For the first nine months of 2019, noninterest income from continuing operations decreased $1.8 million, or 19%, to $8.0 million. The decrease was primarily due to the $1.7 million gain on the sale of Southeastern Trust Company in the second quarter of 2018. Also contributing to the decrease was a $1.0 million, or 100%, decrease in trust income due to the sale of the trust business in the second quarter of 2018. Additionally, derivatives loss for the first nine months of 2019 totaled $637,000 compared to a derivatives gain of $154,000 for the same period in 2018. This was partially offset by a $909,000 increase in the gain on sale of investment securities.

For the third quarter of 2019, noninterest expense from continuing operations increased $805,000 or 7%, to $12.7 million compared to the third quarter of 2018.

RESULTS OF OPERATIONS

Net Interest Income and Net Interest Margin

Taxable equivalent net interest income from continuing operations for the third quarter of 2019 totaled $20.1 million, a $694,000, or 4%, increase compared to the third quarter of 2018. This increase was primarily driven by a $2.5 million, or 10%, increase in taxable equivalent interest income from continuing operations. This was offset by an increase in interest expense from continuing operations for the third quarter of 2019 of $1.8 million, or 38%, when compared to the third quarter of 2018.  The change in taxable equivalent interest income from continuing operations was primarily due to a $3.4 million, or 17%, increase in interest income on loans, resulting from an increase in average loan balances. The change in interest expense from continuing operations was primarily due to an increase in interest expense on deposits of $2.0

42

million, or 64%, resulting from an increase in deposit costs and an increase in average interest-bearing deposit balances.  Net accretion income on the acquired loans discount totaled $35,000 for the three months ended September 30, 2019, compared to $336,000 for the same period in 2018.

During the second quarter of 2019, due to the $167 million in cash paid to the buyer at the closing of the Branch Sale, Atlantic Capital restructured the balance sheet following the transaction with a combination of excess cash, proceeds from sold securities, FHLB borrowings, and brokered deposits.

Interest expense from continuing operations for the three months ended September 30, 2019 totaled $6.5 million, a $2.0 million, or 64%, increase from the same period of 2018. The rate paid on interest bearing liabilities from continuing operations increased 32 basis points from the third quarter of 2018 to the third quarter of 2019, driven by an increase in interest rates on deposits and other borrowings resulting from increases in the Federal Funds rate during 2018.

Taxable equivalent net interest income from continuing operation for the nine months ended September 30, 2019 totaled $60.6 million, a $5.1 million, or 9%, increase compared to the same period in 2018. This increase was primarily driven by an $11.2 million, or 16%, increase in taxable equivalent interest income from continuing operations. The change in taxable equivalent interest income from continuing operations primarily resulted from a $12.5 million, or 22%, increase in interest income on loans, resulting from increases in the Fed Funds rate during 2018 and an increase in average loan balances.

Interest expense from continuing operations for the nine months ended September 30, 2019 totaled $19.0 million, a $6.1 million, or 47%, increase from the same period of 2018, primarily due to a $7.2 million, or 86%, increase in interest paid on deposits. The rate paid on interest bearing liabilities from continuing operations increased 50 basis points from the first nine months of 2018 to the same period of 2019, driven by an increase in interest rates on deposits and other borrowings.

Taxable equivalent net interest margin from continuing operations increased to 3.52% for the three months ended September 30, 2019 compared to 3.48% for the three months ended September 30, 2018. Taxable equivalent net interest margin from continuing operations for the nine months ended September 30, 2019 increased to 3.66% compared to 3.46% for the nine months ended September 30, 2018. The primary reason for the increase in taxable equivalent net interest margin from continuing operations for the three and nine month periods was higher interest rates on loans resulting from Federal Funds rate increases during 2018.

The following table presents information regarding average balances for assets and liabilities, the total dollar amounts of interest income and dividends from average interest-earning assets, the total dollar amounts of interest expense on average interest-bearing liabilities, and the resulting average yields and costs. The yields and costs for the periods indicated are derived by dividing the income or expense by the average balances for assets or liabilities, respectively, for the periods presented. Loan fees are included in interest income on loans.

Provision for Loan Losses

Management considers a number of factors in determining the required level of the allowance for loan losses and the provision required to achieve what is believed to be appropriate reserve level, including historical loss experience, loan growth, credit risk rating trends, nonperforming loan levels, delinquencies, loan portfolio concentrations, and economic and market trends. The provision for loan losses represents management’s determination of the amount necessary to be charged against the current period’s earnings to maintain the allowance for loan losses at a level that it considered adequate in relation to the estimated losses inherent in the loan portfolio.

For the three months ended September 30, 2019, the provision for loan losses from continuing operations was $413,000, a decrease of $432,000 compared to the three months ended September 30, 2018. For the nine months ended September 30, 2019, the provision for loan losses from continuing operations was $1.9 million, an increase of $481,000 compared to the nine months ended September 30, 2018.

46

The lower provision for the third quarter of 2019 compared to the third quarter of 2018 was due to a change in loan mix and lower modeled loss rates. The higher provision for the nine months ended September 30, 2019, compared to the same period in 2018, was primarily related to an increase in net charge-offs as well as an increase in specific reserve impairments during the first two quarters of 2019. At September 30, 2019, nonperforming loans totaled $6.8 million compared to $2.7 million at September 30, 2018. Net loan charge-offs were 0.11% and 0.12%, respectively, of average loans (annualized) for the three and nine months ended September 30, 2019 compared to 0.00% and 0.02%, respectively, for the three and nine months ended September 30, 2018. The increase in net charge-offs was due to commercial and industrial SBA loans charged off in 2019. The allowance for loan losses to total loans at September 30, 2019 was 0.98%, compared to 1.03% at December 31, 2018.

Noninterest Income

Noninterest income from continuing operations for the three and nine months ended September 30, 2019 was $2.8 million and $8.0 million, respectively, compared to $2.3 million and $9.9 million for the comparable periods of the prior year; representing an increase of $514,000 for the three month period and a decrease of $1.9 million for the nine month period. The following table presents the components of noninterest income.

Service charges from continuing operations for the three months ended September 30, 2019 totaled $925,000, an increase of $121,000, or 15%, from the same period in 2018. For the nine months ended September 30, 2019, service charges from continuing operations totaled $2.6 million, an increase of $250,000, or 11%, from the first nine months of 2018. The increase for the three and nine months ended September 30, 2019 compared to the same periods in 2018 was primarily due to higher fees in the payments business and higher foreign exchange fees.

Securities gains from continuing operations for the three and nine months ended September 30, 2019 increased $253,000, and $909,000, respectively from the comparable periods in 2018, as a result of the balance sheet realignment due to the Branch Sale and interest rate risk initiatives.

Trust income for the nine months ended September 30, 2019 decreased $1.0 million, or 100%, compared to the same period in 2018 due to the sale of the trust business in the second quarter of 2018.

Derivatives income (loss) for the third quarter of 2019 was a loss of $293,000, compared to a gain of $20,000 for the same period in 2018. For the nine months ended September 30, 2019, derivatives income decreased $791,000 from the same period in 2018. The decrease in income for both periods was due to changes in the derivatives credit valuation adjustment.

Income from SBA lending activities for the third quarter of 2019 increased $268,000, or 30%, from the same period in 2018, due to an increase in loan balances sold. During the three months ended September 30, 2019 and 2018, guaranteed portions of SBA loans totaling $17.0 million and $11.4 million, respectively, were sold in the secondary market. Income

47

from SBA lending activities for the first nine months of 2019 increased $151,000, or 5%, from the same period in 2018, due to an increase in loan balances sold. During the nine months ended September 30, 2019 and 2018, guaranteed portions of SBA loans with principal balances of $49.7 million and $43.0 million, respectively, were sold in the secondary market.

Noninterest income from discontinued operations increased $32.8 million for the nine months ended September 30, 2019 compared to the same periods in 2018 due to a $34.5 million gain in connection with the Branch Sale.

Noninterest Expense

Noninterest expense from continuing operations for the three and nine months ended September 30, 2019 was $12.7 million and $39.7 million, respectively, compared to $11.9 million and $37.8 million for the comparable periods of the prior year. The following table presents the components of noninterest expense.

Salaries and employee benefits expense from continuing operations for the three months ended September 30, 2019 totaled $8.3 million, an increase of $963,000 or 13%, from the same period in 2018. For the first nine months of 2019, salaries and employee benefits totaled $26.0 million, an increase of $1.8 million, or 8%, from the first nine months of 2018. The increase for the three and nine months ended September 30, 2019, was primarily attributable to severance expense unrelated to the Branch Sale, an increase in medical insurance expense, and new hires made in 2019. Full time equivalent headcount totaled 197 at September 30, 2019, compared to 334 at September 30, 2018, a net decrease of 137 positions, primarily due to a reduction in retail and support staff related to the Branch Sale.

Occupancy costs from continuing operations were $722,000 for the third quarter of 2019, a decrease of $10,000, or 1%, compared to the third quarter of 2018. For the nine months ended September 30, 2019, occupancy costs were $2.1 million, a decrease of $267,000, or 12%, from the first nine months of 2018. The decrease for the nine months ended September 30, 2019, was the result of higher rent expense in the third quarter of 2018 due to the overlap of leases and their expenses from the relocation of the Atlanta headquarters.

Equipment and software costs from continuing operations were $842,000 for the third quarter of 2019, an increase of $95,000, or 13%, compared to the third quarter of 2018. For the nine months ended September 30, 2019, equipment and software costs from continuing operations were $2.3 million, an increase of $300,000, or 15%, from the first nine months of 2018. The increase for both periods was the result of additional investments in technology.

48

Professional services costs from continuing operations were $764,000 for the third quarter of 2019, a decrease of $32,000, or 4%, compared to the third quarter of 2018. For the nine months ended September 30, 2019, professional services costs from continuing operations were $2.3 million, a decrease of $233,000, or 9%, from the first nine months of 2018. The decrease for both periods was primarily due to lower consultant fees.

FDIC premiums expense from continuing operations was ($193,000) for the third quarter of 2019, a decrease of $347,000, compared to the third quarter of 2018. For the nine months ended September 30, 2019, FDIC premiums were $217,000, a decrease of $188,000, or 46%, from the first nine months of 2018. The decrease for the three and nine months ended September 30, 2019 was due to small bank assessment credits issued in the third quarter of 2019.

Income Taxes

Atlantic Capital monitors and evaluates the potential impact of current events on the estimates used to establish income tax expenses and income tax liabilities. On a periodic basis, Atlantic Capital evaluates its income tax positions based on current tax law and positions taken by various tax auditors within the jurisdictions where Atlantic Capital is required to file income tax returns.

The income tax expense from continuing operations for the three and nine months ended September 30, 2019 was $2.1 million and $5.7 million, respectively, compared to $1.8 million and $5.3 million for the same periods in 2018. The effective tax rate (as a percentage of pre-tax earnings) was 21.7% and 21.3%, respectively, for the three and nine months ended September 30, 2019 compared to 20.8% and 20.4%, respectively, for the same period in 2018.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts and their respective tax basis including operating losses and tax credit carryforwards. Net deferred tax assets (deferred tax assets net of deferred tax liabilities and valuation allowance) are reported in the Consolidated Balance Sheets as a component of other assets.

Accounting Standards Codification Topic 740, Income Taxes, requires that companies assess whether a valuation allowance should be established against their deferred tax assets based on the consideration of all available evidence using a “more likely than not” standard. The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires an evaluation of all positive and negative evidence with more weight given to evidence that can be objectively verified. Each quarter, management considers both positive and negative evidence and analyzes changes in near-term market conditions as well as other factors which may impact future operating results.

Based on all evidence considered, as of September 30, 2019 and 2018, management concluded that it was more likely than not that the net deferred tax asset would be realized, except as outlined in the following discussion. At September 30, 2019 and 2018, Atlantic Capital recorded a deferred tax asset valuation allowance totaling $6.8 million and $8.5 million, respectively, on certain net operating loss carryforwards due to the fact that certain tax attributes are subject to an annual limitation as a result of the acquisition of First Security in 2015, which constituted a change of ownership as defined under Internal Revenue Code Section 382. Management expects to generate future taxable income and believes this will allow for full utilization of Atlantic Capital’s remaining net operating loss carryforwards within the statutory carryforward periods.

FINANCIAL CONDITION

Total assets at September 30, 2019 and December 31, 2018 were $2.41 billion and $2.96 billion, respectively. Average total assets for the third quarter of 2019 were $2.45 billion, compared to $2.81 billion in the third quarter of 2018. The decrease in total assets was primarily due to the sale of loans and other assets in connection with the Branch Sale in the second quarter of 2019.

Loans

At September 30, 2019, total loans held for investment increased $108,000, or 6%, to $1.84 billion compared to $1.73 billion at December 31, 2018. Commercial and industrial loans as of September 30, 2019 increased $52.0 million, or 8%,

49

compared to December 31, 2018, and owner occupied commercial real estate loans increased $54.6 million, or 18%, for the same periods. Table 6 provides additional information regarding Atlantic Capital’s loan portfolio.

Nonperforming Assets

Nonperforming assets include nonaccrual loans, accruing loans past due 90 days or more, and other real estate owned. Loans are considered to be past due when payment is not received from the borrower by the contractually specified due date. Interest accruals on loans are discontinued when interest or principal has been in default 90 days or more, unless the loan is both secured by collateral that is sufficient to repay the debt in full and the loan is in the process of collection. When a loan is placed on nonaccrual status, interest accrued and not paid in the current accounting period is reversed against current period income. Interest accrued and not paid in prior periods, if significant, is reversed against the allowance for loan losses.

Income on such loans is subsequently recognized on a cash basis as long as the future collection of principal is deemed probable or after all principal payments are received. Commercial loans are placed back on accrual status after sustained performance of timely and current principal and interest payments and it is probable that all remaining amounts due, both principal and interest, are fully collectible according to the terms of the loan agreement. Residential loans and consumer loans are generally placed back on accrual status when they are no longer past due.

50

Purchased Credit Impaired (“PCI”) loans accounted for under ASC 310‑30 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. PCI loans were not classified as nonaccrual for periods ended prior to December 31, 2018, as the carrying value of the respective loan or pool of loans cash flows were considered estimable and collection was probable. Therefore, interest revenue, through accretion of the difference between the carrying value of the loans and the expected cash flows, was recognized on all PCI loans. As of December 31, 2018, PCI loans were designated as held-for-sale and subsequently sold in the Branch Sale.

At September 30, 2019, Atlantic Capital’s nonperforming assets totaled $7.0 million, or 0.29% of total assets, compared to $6.1 million, or 0.20% of total assets, at December 31, 2018. The increase was primarily due to two loan relationships that were placed on nonaccrual status, offset by the sale of an other real estate property in the third quarter of 2019.

Nonaccrual loans totaled $6.8 million and $4.7 million as of September 30, 2019 and December 31, 2018, respectively. There were no loans past due 90 days and still accruing at September 30, 2019 compared to $479,000 at December 31, 2018. Table 7 provides details on nonperforming assets and other risk elements.

⁽¹⁾ Nonperforming loans as of September 30, 2018 exclude those loans which are PCI loans. As of December 31, 2018, PCI loans were designated as held for sale in the upcoming Branch Sale. As a result, nonperforming loans held for sale which were previously designated as PCI loans are included in total nonperforming loans as of March 31, 2019 and December 31, 2018. Those PCI loans were sold in connection with the closing of the Branch Sale in April 2019.

Troubled Debt Restructurings

Troubled Debt Restructurings (“TDRs”) are selectively made to provide relief to customers experiencing liquidity challenges or other circumstances that could affect their ability to meet their debt obligations. Typical modifications include short-term deferral of interest or modification of payment terms. Nonperforming TDRs are not accruing interest and are included as nonperforming assets within nonaccrual loans. TDRs which are accruing interest based on the restructured terms are considered performing. Table 8 summarizes TDRs.

During the three months ended September 30, 2019, the Company restructured via bankruptcy one commercial real estate SBA loan, resulting in its reclassification as a TDR. For the nine months ended September 30, 2019, restructurings included modifications such as payment deferrals and interest only forbearance.

Potential Problem Loans

Management identifies and maintains a list of potential problem loans. These are loans that are internally risk graded special mention or below but which are not included in nonaccrual status and are not past due 90 days or more. A loan is added to the potential problem list when management becomes aware of information about possible credit problems of the borrower which raises doubts as to the ability of such borrower to comply with the current loan repayment terms. Potential problem loans totaled $52.5 million and $58.2 million as of September 30, 2019 and December 31, 2018, respectively. Management closely tracks the financial performance of the borrower and the current values of collateral when assessing the collectability of these loans.

Allowance for Loan Losses

At September 30, 2019, the allowance for loan losses totaled $18.0 million, or 0.98% of loans, compared to $17.9 million, or 1.03% of loans, at December 31, 2018. The increase in the allowance was primarily related to an increase in outstanding loan balances as well as an increase in specific reserves.

Net charge-offs for the three months ended September 30, 2019 were $519,000 and a net recovery of $15,000 for the three months ended September 30, 2018. Net charge-offs for the nine months ended September 30, 2019 and 2018 were $1.7 million and $345,000, respectively. The increase related primarily to three charge-offs in 2019: a $330,000 net charge-off for a Tennessee commercial and industrial loan not included in the Branch Sale and two net charge-offs on commercial and industrial SBA loans totaling $1.0 million. Table 9 provides details concerning the allowance for loan losses during the past five quarters.

Investment Securities

Investment securities totaled $329.6 million at September 30, 2019, compared to $402.5 million at December 31, 2018. Held-to-maturity securities are carried at amortized cost. Available-for-sale securities are reported at their aggregate fair value, and unrealized gains and losses are included as a component of other comprehensive income, net of deferred taxes. As of September 30, 2019, investment securities available-for-sale had a net unrealized gain of $3.7 million, compared to a net unrealized loss of $11.8 million as of December 31, 2018. Changes in interest rates and credit spreads result in temporary unrealized losses as the market price of securities fluctuate. After evaluating the securities with unrealized losses, management concluded that no other-than-temporary impairment existed as of September 30, 2019.

Changes in the amount of Atlantic Capital’s securities portfolio result primarily from balance sheet trends including loans, deposit balances, and short-term borrowings. When inflows arising from deposits and short-term borrowings exceed loan demand, Atlantic Capital invests excess funds in the securities portfolio or in short-term investments. Conversely, when loan demand exceeds growth in deposits and short-term borrowings, Atlantic Capital allows interest-bearing balances with

53

other banks to decline and uses proceeds from maturing or sold securities to fund loan demand. During the third quarter of 2019, the Company purchased $42.9 million in held-to-maturity municipal securities, in order to extend the duration of the securities portfolio, as well as to reduce the asset sensitivity of the balance sheet.

Details of investment securities at September 30, 2019 and December 31, 2018 are provided in Table 10.

The effective duration of Atlantic Capital’s securities was 5.44 years and 5.26 years at September 30, 2019 and December 31, 2018, respectively.

Goodwill and Other Intangible Assets

Goodwill represents the premium paid for acquired companies above the fair value of the assets acquired and liabilities assumed, including separately identifiable intangible assets. Atlantic Capital evaluates its goodwill annually, or more frequently if necessary, to determine if any impairment exists. Factors that management considers in this assessment includes macroeconomic conditions, industry and market considerations, overall financial performance of the Company, and changes in the composition or carrying amount of net assets. Management concluded that the 2018 annual qualitative impairment assessment indicated that it is more likely than not that the estimated fair value exceeded the carrying value (including goodwill).

On April 5, 2019, the Bank completed the Branch Sale. In accordance with GAAP, Atlantic Capital allocated a proportionate share of its goodwill balance to the discontinued operations on a relative fair value basis and performed an impairment test for the goodwill remaining in the reporting unit to be retained. This impairment analysis of goodwill remaining in the retained reporting unit resulted in no impairment. The Company monitored events from the date of the assessment through September 30, 2019 and no events or circumstances led management to believe any impairment existed at the balance sheet date.

Atlantic Capital’s core deposit intangible representing the value of the acquired deposit base, was an amortizing intangible asset that was required to be tested for impairment only when events or circumstances indicated that impairment may exist. This core deposit intangible was fully amortized in the second quarter of 2019 as a result of the Branch Sale.

LIQUIDITY AND CAPITAL RESOURCES

Deposits

At September 30, 2019, total deposits from continuing operations were $1.9 billion, a decrease of $98.2 million, or 5%, from December 31, 2018. Money market deposits decreased $66.1 million, or 7%, from December 31, 2018 to September 30, 2019. The decrease was the result of seasonal volatility and a large increase in temporary deposits during the quarter ended December 31, 2018.

Total average deposits from continuing operations for the quarter ended September 30, 2019 were $1.95 billion, an increase of $297.0 million, or 18%, from the same period in 2018. For the quarter ended September 30, 2019 compared to the same period in 2018, average noninterest-bearing demand deposits from continuing operations increased $76.5 million, or 14%, and average money market deposits from continuing operations increased $197.5 million, or 28%. Table 11 provides additional information regarding deposits during the past five quarters.

Short-Term Borrowings

At September 30, 2019 and December 31, 2018, balances of federal funds purchased were $57.0 million and $0, respectively. There were securities sold under repurchase agreements with commercial checking customers totaling $0 and $6.2 million as of September 30, 2019 and December 31, 2018, respectively. This balance was classified as discontinued operations in the Consolidated Balance Sheets as of December 31, 2018.

As a member of the Federal Home Loan Bank of Atlanta (“FHLB”), Atlantic Capital has the ability to acquire short and long-term advances through a blanket agreement secured by our unencumbered qualifying 1‑4 family first mortgage loans and by pledging investment securities or individual, qualified loans, subject to approval of the FHLB. At September 30, 2019 and December 31, 2018, Atlantic Capital had FHLB advances of $76.0 million and $0, respectively. FHLB borrowings increased due to an increase in short-term funding needs.

Long-Term Debt

During the third quarter of 2015, Atlantic Capital issued $50.0 million in fixed-to-floating rate subordinated notes due in 2025, and callable on September 30, 2020, all of which were outstanding at September 30, 2019. The notes bear a fixed rate of 6.25% per year until September 29, 2020, and then bear a floating rate of three month LIBOR plus 468 basis points until maturity.

Liquidity Risk Management

Liquidity risk is the risk that an institution will be unable to generate or obtain sufficient funding, at a reasonable cost, to meet operational cash needs and to take advantage of revenue producing opportunities as they arise. Other forms of liquidity risk include market constraints on the ability to convert assets into cash at expected levels, an inability to access funding sources at sufficient levels at a reasonable cost, and changes in economic conditions or exposure to credit, market, operational, legal, and reputation risks that can affect an institution’s liquidity risk profile. Liquidity management involves maintaining Atlantic Capital’s ability to meet the daily cash flow requirements of Atlantic Capital’s customers, both depositors and borrowers.

Atlantic Capital utilizes various measures to monitor and control liquidity risk across three different types of liquidity:

· tactical liquidity measures the risk of a negative cash flow position whereby cash outflows exceed cash inflows over a short-term horizon;

· structural liquidity measures the amount by which illiquid assets are supported by long-term funding; and

· contingent liquidity utilizes cash flow stress testing across four crisis scenarios to determine the adequacy of Atlantic Capital’s liquidity.

Atlantic Capital aims to maintain a diverse mix of existing and potential liquidity sources to support the liquidity management function. At its core is a reliance on the customer deposit book, due to the low cost it offers. Other sources of liquidity include asset-based liquidity in the form of cash and unencumbered securities, as well as access to wholesale funding from external counterparties, primarily advances from the FHLB of Atlanta, federal funds lines and other borrowing facilities. Atlantic Capital aims to avoid funding concentrations by diversifying external secured and unsecured funding with respect to maturities, counterparties and nature. At September 30, 2019, management believed that Atlantic Capital had sufficient on-balance sheet liquidity to meet its funding needs.

On April 5, 2019, the Bank completed the Branch Sale. FirstBank assumed deposits and customer repurchase agreements of approximately $598 million and purchased approximately $385 million in loans and $12 million in other assets. Since Atlantic Capital divested a larger amount of deposits than assets, it made a cash payment of approximately $167 million to FirstBank at the closing of the Branch Sale. The Company restructured the balance sheet following the Branch Sale with a combination of excess cash, proceeds from sold securities, FHLB borrowings, and brokered deposits.

56

At September 30, 2019, Atlantic Capital had access to $438.0 million in unsecured borrowings and $592.7 million in secured borrowings through various sources, including FHLB advances and access to Federal Funds. Atlantic Capital also has the ability to attract more deposits by increasing rates.

Shareholders’ Equity and Capital Adequacy

Shareholders’ equity at September 30, 2019 was $328.7 million, an increase of $5.0 million, or 2%, from December 31, 2018. Net income of $42.7 million for the first nine months of 2019, and an increase of $16.8 million in accumulated other comprehensive income, were offset by $56.7 million in share repurchases. Atlantic Capital and the Bank are required to meet minimum capital requirements imposed by regulatory authorities. Failure to meet certain capital requirements may result in actions by regulatory agencies that could have a material impact on Atlantic Capital’s consolidated financial statements. Tables 12 and 13 provide additional information regarding regulatory capital requirements and Atlantic Capital’s and the Bank’s capital levels. Accumulated other comprehensive income, which includes unrealized gains and losses on securities available-for-sale and unrealized gains and losses on derivatives qualifying as cash flow hedges, is excluded in the calculation of regulatory capital ratios.

As of September 30, 2019, Atlantic Capital continued to exceed minimum capital standards and the Bank remained “well-capitalized” under regulatory guidelines.

In July 2013, bank regulatory agencies approved the Basel III capital guidelines, which are aimed at strengthening existing capital requirements for bank holding companies through a combination of higher minimum capital requirements, new capital conservation buffers and more conservative definitions of capital and balance sheet exposure. Atlantic Capital and the Bank became subject to the requirements of Basel III effective January 1, 2015, subject to a transition period providing for full compliance after January 1, 2019 for several aspects of the rule.

Management continues to monitor Basel III developments and remains committed to managing Atlantic Capital’s capital levels in a prudent manner.

Off-Balance Sheet Arrangements

Atlantic Capital makes contractual commitments to extend credit and issues standby letters of credit in the ordinary course of its business activities. These commitments are legally binding agreements to lend money to customers at predetermined interest rates for a specified period of time. In addition to commitments to extend credit, Atlantic Capital also issues standby letters of credit which are assurances to a third party that it will not suffer a loss if the customer fails to meet a contractual obligation to the third party. At September 30, 2019, Atlantic Capital had issued commitments to extend credit of approximately $679.7 million and standby letters of credit of approximately $7.6 million through various types of commercial lending arrangements.

Based on historical experience, many of the commitments and letters of credit will expire unfunded. Through its various sources of liquidity, Atlantic Capital believes it will be able to fund these obligations as they arise. Atlantic Capital evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on Atlantic Capital’s credit evaluation of the borrower. Collateral varies but may include accounts receivable, inventory, property, plant and equipment, and commercial and residential real estate.

Contractual Obligations

There have been no significant changes in Atlantic Capital’s contractual obligations at September 30, 2019 compared to December 31, 2018.

RISK MANAGEMENT

Effective risk management is critical to Atlantic Capital’s success. The Dodd-Frank Act requires that bank holding companies with total assets in excess of $10 billion establish an enterprise-wide risk committee consisting of members of its board of directors. Although Atlantic Capital does not have total assets in excess of $10 billion, the Bank’s board of directors has an Audit and Risk Committee that, among other responsibilities, provides oversight of enterprise-wide risk management activities. The Audit and Risk Committee reviews the Bank’s activities in identifying, measuring, and mitigating existing and emerging risks (including credit, liquidity, interest-rate, compliance, operational, strategic, and reputational risks.) The committee monitors management’s execution of risk management practices in accordance with the board of directors’ risk appetite, reviews supervisory examination reports together with management’s response to such examinations and discusses legal matters that may have a material impact on the financial statements or Atlantic Capital’s compliance policies. With guidance from and oversight by the Audit and Risk Committee, management continually refines and enhances its risk management policies and procedures to maintain effective risk management programs and processes.

Credit Risk

Credit risk is the risk of not collecting payments pursuant to the contractual terms of loans, leases, investment securities, and derivative instruments. Atlantic Capital’s independent loan review function conducts risk reviews and analyses of loans to help assure compliance with credit policies and to monitor asset quality trends. The risk reviews include portfolio analysis by industry, collateral type and product. Atlantic Capital strives to identify potential problem loans as early as

58

possible, to record charge-offs or write-downs as appropriate and to maintain adequate allowances for loan losses that are inherent in the loan portfolio.

Market Risk

Market risk reflects the risk of economic loss resulting from adverse changes in market prices and interest rates. This risk of loss can be reflected in diminished current market values and/or reduced potential nets interest income in future periods. Atlantic Capital’s market risk arises primarily from interest rate risk inherent in Atlantic Capital’s lending and deposit-taking activities. The structure of Atlantic Capital’s loan and deposit portfolios is such that a significant decline in interest rates may adversely impact net market values and net interest income. Atlantic Capital does not maintain a trading account nor is Atlantic Capital subject to currency exchange risk or commodity price risk.

Interest Rate Risk

Interest rate risk results principally from assets and liabilities maturing or repricing at different points in time, from assets and liabilities repricing at the same point in time but in different amounts and from short-term and long-term interest rates changing in different magnitudes. Market interest rates also have an impact on the interest rate and repricing characteristics of loans that are originated as well as the rate characteristics of interest-bearing liabilities. Atlantic Capital assesses interest rate risk by forecasting net interest income under various interest rate scenarios and comparing those results to forecasted net interest income assuming stable rates. With rates rising, the estimated increase in net interest income is primarily due to the short-term repricing characteristics of the loan portfolio, combined with a favorable funding mix. Atlantic Capital’s loan book consists mainly of floating rate loans. Atlantic Capital’s core client deposits are likely to allow Atlantic Capital to lag short-term interbank rate indices when pricing deposits. Transaction accounts comprise a significant amount of Atlantic Capital’s total deposits.

Table 14 provides the impact on net interest income resulting from various interest rate shock scenarios as of September 30, 2019 and December 31, 2018.

+200	13.78		13.52

Atlantic Capital also utilizes the market value of equity (“MVE”) as a tool in measuring and managing interest rate risk. Long-term interest rate risk exposure is measured using the MVE sensitivity analysis to study the impact of long-term cash flows on capital. Table 15 presents the MVE profile as of September 30, 2019 and December 31, 2018.

ITEM 3.              QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information required by this item is included in Part I, Item 2 of this report under “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Risk Management.”

ITEM 4.              CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures as required under Rule 13a‑15 promulgated under the Exchange Act, that are designed to ensure that information required to be disclosed in the Company’s Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. As of September 30, 2019, the Company’s management carried out an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of its disclosure controls and procedures. Based on their evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2019. No changes were made to the Company’s internal control over financial reporting (as defined in Rule 13a‑15(f) promulgated under the Exchange Act) during the quarter ended September 30, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1.              LEGAL PROCEEDINGS

In the ordinary course of operations, Atlantic Capital and the Bank are, from time to time, defendants in various legal proceedings. Additionally, in the ordinary course of business, Atlantic Capital and the Bank are subject to regulatory examinations and investigations. Based on our current knowledge and advice of counsel, in the opinion of management there is no such pending or threatened legal or regulatory matter which would result in a material adverse change, either individually or in the aggregate, in the consolidated financial condition or results of operations of Atlantic Capital.

ITEM 1A.           RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in the Company’s Annual Report on Form 10‑K for the period ended December 31, 2018, under Part I, Item 1A “Risk Factors,” because these risk factors may affect the operations and financial results of the Company. Our evaluation of our risk factors has not changed materially since those discussed in the Annual Report. The risks described in the Annual Report are not the only risks facing the Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, and operating results.

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

(a)          None.

(b)          Not applicable.

(c)          On November 14, 2018, the Company announced that the Board of Directors authorized a stock repurchase program pursuant to which the Company may purchase up to $85 million of its issued and outstanding common stock. The repurchase program commenced immediately with respect to $40 million of stock. In September 2019, the Bank received regulatory approval to pay a dividend of $20 million to Atlantic Capital. We may need to seek regulatory approval for additional dividends by the Bank in order to repurchase all shares that we are currently authorized to repurchase. The timing and amounts of any repurchases will depend on certain factors, including but not limited to market conditions and prices, available funds and alternative uses of capital. The stock repurchase program may be carried out through open-market purchases, block trades, negotiated private transactions and pursuant to a trading plan adopted in accordance with Rule 10b‑18 or Rule 10b5‑1 under the Securities Exchange Act of 1934. The stock repurchase program may be suspended or discontinued at any time and will automatically expire on November 14, 2020. Any repurchased shares will constitute authorized but unissued shares.

During the three months ended September 30, 2019, the Company repurchased 1.2 million shares of common stock for $20.1 million. The following table presents information with respect to repurchases of our common shares during the periods indicated:

Revenue Recognition

NOTE 16 – REVENUE RECOGNITION

On January 1, 2018, the Company adopted ASU No. 2014‑09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent ASUs that modified Topic 606. As stated in Note 2, Accounting Standards Updates and Recently Adopted Standards, the implementation of the new standard did not result in any significant changes to the Company’s methodology of recognizing revenue; as such, the Company recorded an immaterial cumulative effect adjustment to first quarter 2018 opening retained earnings. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historic accounting under Topic 605.

Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with financial guarantees and derivatives are not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as service charges on deposit accounts and trust and asset management income. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams within the scope of Topic 606 are discussed below.

Service Charges on Deposit Accounts

Service charges represent general service fees for monthly account maintenance and activity, or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed, such as a wire transfer or ATM withdrawal. Payment for such performance obligations are generally received at the time the performance obligations are satisfied. The following table presents service charges by type of service provided for the three and nine months ended September 30, 2019 and 2018:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2019		2018		2019		2018
Deposit account analysis fees and charges	$	672	$	566	$	1,894	$	1,601
ATM fees		—		56		39		162
NSF fees		18		20		40		86
Wire fees		124		110		336		303
Foreign exchange fees		110		50		275		176
Other		1		2		5		11
Total service charges - continuing operations		925		804		2,589		2,339
Service charges - discontinued operations		—		474		527		1,439
Total service charges	$	925	$	1,278	$	3,116	$	3,778

Trust and Asset Management

Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. During the second quarter of 2018, Atlantic Capital sold its trust business, Southeastern Trust Company. The following table presents trust income by type of service provided for the three and nine months ended September 30, 2018:

	For the Three Months Ended September 30,					For the Nine Months Ended September 30,
	2019		2018		2019		2018
Personal trust and agency accounts	$	—	$	—	$	—	$	616
Employee benefit and retirement-related trust and agency accounts		—		—		—		120
Investment management and investment advisory agency accounts		—		—		—		217
Custody and safekeeping accounts		—		—		—		26
Other		—		—		—		46
	$	—	$	—	$	—	$	1,025

Other

Other noninterest income consists of other recurring revenue streams such as check printing income, safety deposit box rental fees, and other miscellaneous revenue streams. Check printing income is recognized ratably over the contract period as the Company satisfies its performance obligation to sell a specific number of check packages. Safe deposit box rental fees are charged to the customer annually and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation.

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of September 30, 2019 and December 31, 2018, the Company did not have any significant contract balances.

NOTE 8 – SERVICING ASSETS

SBA Servicing Assets

SBA servicing assets are initially recorded at fair value. Subsequently, Atlantic Capital accounts for SBA servicing assets using the amortization method and they are included in other intangibles, net on the Consolidated Balance Sheets. As of September 30, 2019 and December 31, 2018, the balance of SBA loans sold and serviced by Atlantic Capital totaled $184.6 million and $161.5 million, respectively.

Changes in the balance of servicing assets for the three and nine months ended September 30, 2019 and 2018 are presented in the following table.

	Three Months Ended September 30,				Nine Months Ended September 30,
SBA Loan Servicing Assets	2019		2018		2019		2018
	(in thousands)				(in thousands)
Beginning carrying value, net	$	2,726	$	2,827	$	2,539	$	2,635
Additions		350		120		975		739
Amortization		(296)		(239)		(734)		(666)
Impairment		—		—		—		—
Ending carrying value	$	2,780	$	2,708	$	2,780	$	2,708

At September 30, 2019 and December 31, 2018, the sensitivity of the fair value of the SBA loan servicing assets to immediate changes in key economic assumptions are presented in the table below.

Sensitivity of the SBA Servicing Assets	September 30, 2019			December 31, 2018
	(dollars in thousands)
Fair value of retained servicing assets	$	3,029		$	2,630
Weighted average life		3.90 years			4.83 years
Prepayment speed:		14.71	%		11.92	%
Decline in fair value due to a 10% adverse change	$	(160)		$	(131)
Decline in fair value due to a 20% adverse change	$	(271)		$	(223)
Weighted average discount rate		14.01	%		14.42	%
Decline in fair value due to a 100 bps adverse change	$	(107)		$	(101)
Decline in fair value due to a 200 bps adverse change	$	(169)		$	(165)

The above sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on valuation assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities.

TriNet Servicing Assets

Changes in the balance of TriNet servicing assets for the three and nine months ended September 30, 2019 and 2018 are presented in the following table.

	Three Months Ended September 30,				Nine Months Ended September 30,

At September 30, 2019 and December 31, 2018, the sensitivity of the fair value of the TriNet servicing assets to immediate changes in key economic assumptions are presented in the table below.

Sensitivity of the TriNet Servicing Assets	September 30, 2019			December 31, 2018
	(dollars in thousands)
Fair value of retained servicing assets	$	453		$	515
Weighted average life		5.77 years			6.48 years

Decline in fair value due to a 100 bps adverse change	$	(10)		$	(13)
Decline in fair value due to a 200 bps adverse change	$	(20)		$	(25)

The above sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on valuation assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated without changing any other assumption.

Management evaluates securities for other-than-temporary impairment on a quarterly basis. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, among other factors. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and internal and external analyst reviews.

At September 30, 2019, there were 77 available-for-sale securities and 7 held-to-maturity securities that were in an unrealized loss position. Atlantic Capital does not intend to sell and does not believe it will be required to sell securities in an unrealized loss position prior to the recovery of their amortized cost basis. Unrealized losses at September 30, 2019 and December 31, 2018 were attributable to changes in interest rates. No impairment charges on securities were recognized during the three or nine months ended September 30, 2019 or 2018.

Realized gains and losses are derived using the specific identification method for determining the cost of securities sold. The following table summarizes securities sales activity for the three and nine months ended September 30, 2019 and 2018.

Investment securities with a carrying value of $32.3 million and $65.3 million were pledged to secure public funds and other borrowings at September 30, 2019 and December 31, 2018, respectively.

As of September 30, 2019 and December 31, 2018, Atlantic Capital had investments with a carrying value of $4.4 million and $4.4 million, respectively, in Small Business Investment Companies (“SBICs”) where Atlantic Capital is the limited partner. These investments are included in other assets on the Consolidated Balance Sheets. During the nine months ended September 30, 2019 and 2018, the Company recorded impairments in the amounts of $26,000 and $228,000, respectively, on these SBICs. The impairments resulted from deterioration in the credit quality of one of the SBICs and their inability to pay distributions until their financial position improves.

Leases

NOTE 17 – LEASES

A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016‑02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842. For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee.

Operating leases in which the Company is the lessee are recorded as operating lease ROU assets and operating lease liabilities, included in premises and equipment and other liabilities, respectively, on the Consolidated Balance Sheets. The Company does not currently have any significant finance leases in which it is the lessee.

Operating lease ROU assets represent the Company’s right to use an underlying asset during the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents the Company’s incremental borrowing rate at the lease commencement date. ROU assets are further adjusted for lease incentives. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in net occupancy expense in the Consolidated Statements of Income.

The Company’s leases relate primarily to office space and bank branches with remaining lease terms of generally 1 to 12 years. Certain lease arrangements contain extension options which typically range from 5 to 10 years at the then fair market rental rates. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. Portions of certain properties are subleased for terms extending through 2024. As of September 30, 2019, operating lease ROU assets and liabilities were $9.9 million and $13.9 million, respectively. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the Consolidated Balance Sheets. Additionally, the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component.

The table below summarizes the Company’s net lease cost:

	Three Months Ended		Nine Months Ended

On April 5, 2019, Atlantic Capital completed the sale to FirstBank of its Tennessee and northwest Georgia banking operations, including 14 branches. Eight of these properties were owned by Atlantic Capital and nine were leased. The Company’s ROU asset and lease liability were reduced during the second quarter of 2019 by $3.6 million and $4.1 million, respectively, as a result of this divestiture.

Share-Based Compensation

Share-Based Compensation

NOTE 13 – SHARE-BASED COMPENSATION

Atlantic Capital sponsors a stock incentive plan for the benefit of directors and employees. Under the Company’s 2015 Stock Incentive Plan (as amended and restated effective May 16, 2018), there were approximately 4,525,000 shares reserved for issuance to directors and employees. The Compensation Committee has the authority to grant the following: an incentive or nonqualified option; a restricted stock award (including a restricted stock award or a restricted unit award); a performance award (including a performance share award or a performance unit award); a phantom stock award; a dividend equivalent award; or any other award granted under the plan.

As of September 30, 2019, approximately 3,345,000 additional awards were available to be granted under the plan. Stock options are granted at a price which is no less than the fair market value of a share of Atlantic Capital common stock on the grant date. Stock options generally vest over three years and expire after ten years.

The Company estimates the fair value of its options awards using the Black-Scholes option pricing model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The table below summarizes the assumptions used to calculate the fair value of options granted/modified during the nine months ended September 30, 2019 and 2018:

	For the nine months ended September 30,
	2019		2018
Risk‑free interest rate	2.27	%	1.66	%
Expected term in years	1.73-1.82		0.25
Expected stock price volatility	26.8	%	24.2	%
Dividend yield	—	%	—	%

The following table represents stock option activity for the nine months ended September 30, 2019:

					Weighted  Average

			Average		Contractual Term	Intrinsic Value

Outstanding, December 31, 2018		442,454	$	12.02

Forfeited(1)		(38,500)		13.17

Exercisable, September 30, 2019		309,330	$	11.21	2.38	$	1,971

⁽¹⁾ During the nine months ended September 30, 2019, the Company modified options for 12,500 shares. The modifications are included as shares granted/modified and as shares forfeited in this table.

Atlantic Capital recognized compensation expense relating to stock options of $18,000 and $151,000 for the three and nine months ended September 30, 2019, respectively, and $70,000 and $167,000 for the three and nine months ended September 30, 2018, respectively. Using the Black-Scholes pricing model, the amount of compensation expense was determined based on the fair value of the options at the time of grant, multiplied by the number of options granted that were expected to vest, which was then amortized over the vesting period. In April 2018, the Company granted performance share awards to members of executive management under Atlantic Capital’s Long Term Incentive Plan (“LTIP”). The Company also granted restricted stock awards to certain employees and directors in 2019 under the 2015 Stock Incentive Plan.

The following table represents restricted stock and performance share award activity for the nine months ended September 30, 2019:

		Weighted Average Grant-
	Shares	Date Fair Value
Outstanding, December 31, 2018	272,695	$	18.09
Granted/modified(1)	158,593		19.19
Vested	(68,198)		16.54
Forfeited(1)	(67,663)		18.34
Outstanding, September 30, 2019	295,427	$	18.97

⁽¹⁾ During the nine months ended September 30, 2019, the Company modified 4,719 restricted stock awards. The modifications are included as shares granted/modified and as shares forfeited in this table.

Compensation expense for restricted stock is based on the fair value of restricted stock awards at the time of grant, which is equal to the value of Atlantic Capital’s common stock on the date of grant. Compensation expense for performance share awards is based on the fair value of Atlantic Capital’s stock at the grant date adjusted for market conditions, as well as the subsequent achievement of performance conditions over the vesting period. The value of restricted stock and performance share grants that are expected to vest is amortized into expense over the vesting period. For the three months ended September 30, 2019 and 2018, compensation expense of $454,000 and $444,000, respectively, was recognized related to restricted stock and performance share awards. For the nine months ended September 30, 2019 and 2018, compensation expense of $1.2 million and $1.3 million respectively, was recognized related to restricted stock and performance share awards.

As of September 30, 2019, there was $2.6 million of unrecognized compensation cost related to restricted stock awards granted under the plan. That cost is expected to be recognized over a weighted-average period of 2.27 years.

During the nine months ended September 30, 2019, the Company modified options for 12,500 shares and 4,719 restricted stock awards to two individuals. The modifications allowed for the immediate vesting of the awards upon retirement, as defined in the 2015 Stock Incentive Plan. The total incremental cost resulting from the modifications was $31,000 for the nine months ended September 30, 2019.

Derivatives and Hedging

NOTE 11 – DERIVATIVES AND HEDGING

Risk Management

Atlantic Capital’s objectives in using interest rate derivatives are to add stability to net interest revenue and to manage its exposure to interest rate movements. To accomplish these objectives, Atlantic Capital primarily uses interest rate swaps as part of its interest rate risk management strategy.

Cash Flow Hedges

At September 30, 2019, Atlantic Capital’s interest rate swaps designated as cash flow hedges involve the payment of floating-rate amounts to a counterparty in exchange for receiving fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. At September 30, 2019 and December 31, 2018, Atlantic Capital had interest rate swaps designated as cash flow hedges with aggregate notional amounts of $175.0 million and $100.0 million, respectively.

No hedge ineffectiveness gains or losses were recognized on active cash flow hedges for the three and nine months ended September 30, 2019 and 2018. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Atlantic Capital expects that approximately $230,000 will be reclassified as an increase to loan interest income over the next twelve months related to these cash flow hedges.

Customer Swaps

Atlantic Capital also enters into derivative contracts, which consist of interest rate swaps, to facilitate the needs of customers desiring to manage interest rate risk. These swaps are not designated as accounting hedges under ASC 815, Derivatives and Hedging. To economically hedge the interest rate risk associated with offering this product, Atlantic Capital simultaneously enters into derivative contracts with third parties to offset the customer contracts, such that Atlantic Capital minimizes its net risk exposure resulting from such transactions. The derivative contracts are structured such that the notional amounts reduce over time to generally match the expected amortization of the underlying loans. These derivatives are not speculative and arise from a service provided to clients.

Atlantic Capital’s derivative instruments are recorded at fair value in other assets and accrued interest receivable and other liabilities and accrued interest payable in the Consolidated Balance Sheets. The changes in the fair value of the derivative instruments are recognized in derivatives income in the Consolidated Statements of Income. At September 30, 2019 and December 31, 2018, Atlantic Capital had interest rate swaps related to this program with an aggregate notional amount of $92.5 million and $109.5 million, respectively.

Atlantic Capital acquired a loan level hedging program, which First Security Group, Inc. (“First Security”) utilized to accommodate clients preferring a fixed rate loan. The loan documents include an addendum with a zero premium collar. The zero premium collar is a cap and a floor at the same interest rate, resulting in a fixed rate to the borrower. To hedge this embedded option, First Security entered into a dealer facing trade exactly mirroring the terms in the loan addendum. At September 30, 2019 and December 31, 2018, Atlantic Capital had interest rate swaps related to this program with an aggregate notional amount of $150.4 million and $166.8 million, respectively.

Counterparty Credit Risk

As a result of its derivative contracts, Atlantic Capital is exposed to credit risk. Specifically approved counterparties and exposure limits are defined. Quarterly, the customer derivative contracts and related counterparties are evaluated for credit risk and an adjustment is made to the contract’s fair value. This adjustment is recognized in the Consolidated Statements of Income.

Most derivative contracts with clients are secured by collateral. Additionally, in accordance with the interest rate agreements with derivatives dealers, Atlantic Capital may be required to post margin to these counterparties. At September 30, 2019 and December 31, 2018, Atlantic Capital had minimum collateral posting thresholds with certain of its derivative counterparties and posted collateral of $14.3. million and $5.1 million, respectively, against its obligations under these agreements. Cash collateral related to derivative contracts is recorded in other assets in the Consolidated Balance Sheets.

Atlantic Capital has master netting agreements with the derivatives dealers with which it does business, but reflects gross assets and liabilities on the Consolidated Balance Sheets.

In conjunction with the FASB’s fair value measurement guidance, management made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting arrangements on a net basis.

To accommodate clients, Atlantic Capital occasionally enters into credit risk participation agreements with counterparty banks to accept a portion of the credit risk related to interest rate swaps. This allows clients to execute an interest rate swap with one bank while allowing for distribution of the credit risk among participating members. Credit risk participation agreements arise when Atlantic Capital contracts with other financial institutions, as a guarantor, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third party default on the underlying swap. At September 30, 2019 and December 31, 2018, Atlantic Capital had credit risk participation agreements with a notional amount of $8.1 million and $9.5 million, respectively.

The following table reflects the estimated fair value positions of derivative contracts and credit risk participation agreements as of September 30, 2019 and December 31, 2018:

Commitments and Contingencies

NOTE 15 – COMMITMENTS AND CONTINGENCIES

Atlantic Capital is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and letters of credit, most of which are standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the Consolidated Balance Sheets. The contract amounts of these instruments reflect the extent of involvement Atlantic Capital has in particular classes of financial instruments.

Standby letters of credit are written conditional commitments issued by Atlantic Capital to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. Most letters of credit expire in less than one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Atlantic Capital’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. Atlantic Capital uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Atlantic Capital’s maximum exposure to credit risk for unfunded loan commitments and standby letters of credit at September 30, 2019 and December 31, 2018 was as follows:

	September 30, 2019		December 31, 2018
	(in thousands)
Financial Instruments whose contract amount represents credit risk:
Commitments to extend credit	$	679,732	$	715,591
Standby letters of credit		7,563		15,650
	$	687,295	$	731,241
Minimum lease payments	$	16,669	$	22,014

The Company also had commitments related to investments in SBICs totaling $2.9 million and $3.2 million at September 30, 2019 and December 31, 2018, respectively.

From time to time, Atlantic Capital, in the normal course of business, is subject to various pending and threatened lawsuits in which claims for monetary damages are asserted. Although it is not possible to predict the outcome of these lawsuits, or the range of any possible loss, management, after consultation with legal counsel, does not anticipate that the ultimate aggregate liability, if any, arising from these lawsuits will have a material adverse effect on Atlantic Capital’s financial position or results of operations.

Accounting Standards Updates and Recently Adopted Standards

Basis of Presentation

Basis of Presentation

The accounting and financial reporting policies of Atlantic Capital Bancshares, Inc. (“Atlantic Capital” or the “Company”) and its subsidiary, Atlantic Capital Bank, N.A. (the “Bank”), conform to accounting principles generally accepted in the United States of America (“GAAP”) and general banking industry practices. The accompanying interim consolidated financial statements have not been audited. All material intercompany balances and transactions have been eliminated.

In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in Atlantic Capital’s Annual Report on Form 10‑K. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. Certain prior period amounts have been reclassified to conform to the current year presentation

Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016‑02, “Leases.” Under the new guidance, leases classified as operating leases under previous GAAP must be recorded on the balance sheet. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use (“ROU”) asset representing its right to use the underlying asset for the lease term. In July 2018, the FASB issued ASU No. 2018‑10, “Codification Improvements to Topic 842, Leases and ASU No. 2018‑11, Leases (Topic 842): Targeted Improvements.”  ASU No. 2018‑10 provides improvements related to ASU No. 2016‑02 to increase stakeholders’ awareness of the amendments and to expedite the improvements. The amendments affect narrow aspects of the guidance issued in ASU No. 2016‑02. ASU No. 2018‑11 allows entities adopting ASU No. 2016‑02 to choose an additional (and optional) transition method, under which an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The amendments in these updates became effective for the Company on January 1, 2019. The impact of adoption was recording a lease liability of approximately $18.9 million in other liabilities on the Consolidated Balance Sheets, a ROU asset of approximately $14.5 million in premises and equipment, and a cumulative effect adjustment to retained earnings, net of tax, of approximately $373,000.

Recently Issued Accounting Pronouncements Not Yet Adopted

In May 2019, the FASB issued ASU No. 2019‑05, “Financial Instruments - Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016‑13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of Accounting Standards Codification (“ASC”) 326‑20 if the instruments are eligible for the fair value option under ASC 825‑10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. ASU 2019‑05 has the same effective date as ASU 2016‑13 (i.e., the first quarter of 2020). The Company does not expect to elect the fair value option, and therefore, ASU 2019‑05 is not expected to impact the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018‑13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” The amendments in this update modify the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The update is effective for interim and annual periods in fiscal years beginning after December 31, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for new disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The adoption will not have a material effect on the Company’s consolidated financial statements.

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.” This guidance shortens the premium amortization period for certain callable debt securities by requiring amortization to the earliest call date. The standard is effective for public companies for annual and interim periods beginning after December 15, 2020. The adoption of this update is not expected to have a material impact on Atlantic Capital’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which intends to simplify goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The update instead requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017‑04 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. Atlantic Capital does not expect the new guidance to have a material impact on its financial condition or results of operations.

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 an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016‑13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. ASU 2016‑13 is effective for public companies for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is implementing a software package supported by a third-party vendor. The Company’s CECL working group is meeting regularly with a CECL Management Group and the Company’s Board of Directors to discuss implementation progress and methodology selections. Progress has been made on life-of-loan loss calculations and on economic forecasting methods that will be utilized in the modeling process. The Company continues to refine its new methodology leading up to the adoption of the ASU and will continue to evaluate the impact of the adoption on the Company’s consolidated financial statements and disclosures.

Fair Value Measurements

NOTE 14 – FAIR VALUE MEASUREMENTS

Atlantic Capital follows the guidance pursuant to ASC 820‑10, Fair Value Measurements and Disclosures. This guidance defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. This issuance applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances. Atlantic Capital measures its investment securities and interest rate derivative assets and liabilities at fair value on a recurring basis. Fair value is used on a nonrecurring basis either when assets are evaluated for impairment or for disclosure purposes. Atlantic Capital measures its servicing assets, goodwill, intangible assets, SBIC investments, loans held for sale, impaired loans and other real estate owned at fair value on a nonrecurring basis if necessary.

The guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement and defines fair value as the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, this guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Atlantic Capital applied the following fair value hierarchy:

Level 1 – Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts.

Level 2 – Assets or liabilities valued based on observable market data for similar instruments.

Level 3 – Assets or liabilities for which significant valuation assumptions are not readily observable in the market, instruments valued based on the best available data, some of which is internally-developed, and risk premiums that a market participant would require.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement. There were no transfers between Level 1 and Level 2 or Level 2 and Level 3 during the three or nine months ended September 30, 2019 and 2018.

Atlantic Capital records investment securities available-for-sale at fair value on a recurring basis. Investment securities classified as available-for-sale are reported at fair value utilizing Level 2 inputs. For these securities, Atlantic Capital obtains fair value measurements from an independent pricing service. In estimating the fair values for investment securities, Atlantic Capital believes that independent third-party market prices are the best evidence of an exit price. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the Treasury Department yield curve, trade execution data, market consensus prepayment speeds, credit information and the securities’ terms and conditions, among other things.

Derivative instruments are primarily transacted as over-the-counter trades and priced with observable market assumptions. Ongoing measurements include observable market assumptions with appropriate valuation adjustments for liquidity and for credit risk of counterparties and Atlantic Capital’s own credit. For these instruments, Atlantic Capital obtains fair value measurements from an independent pricing service. The fair value measurements consider factors such as the likelihood of default by Atlantic Capital and its counterparties, total exposure and remaining maturities in determining the appropriate fair value adjustments to record. Generally, the expected loss of each client counterparty is estimated using Atlantic Capital’s internal risk rating system. For financial institution counterparties that are rated by national rating agencies, those ratings are used in determining the credit risk. This approach used to estimate exposures to counterparties is also used by Atlantic Capital to estimate its own credit risk on derivative liability positions.

For the nine months ended September 30, 2019 and 2018, there was not a change in the methods and significant assumptions used to estimate fair value.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

The following table presents the assets that were measured at fair value on a nonrecurring basis by level within the fair value hierarchy as reported in the Consolidated Balance Sheets at September 30, 2019 and December 31, 2018.

Level 3 loans consist of impaired loans which have been partially charged-off or have specific valuation allowances. The fair value of Level 3 assets is estimated based on the underlying collateral value. For loans which the cash proceeds from the sale of the underlying collateral is the expected source of repayment, the fair value of these loans was derived from internal estimates of the underlying collateral incorporating market data, including third party appraisals or evaluations, when available. Appraised values may be discounted based on management’s assessment of the level of inactivity in the real estate market and other markets for the underlying collateral, changes in market conditions from the time of the valuation, and other information that in management’s judgment may affect the value. Impaired loans are evaluated on at least a quarterly basis and adjusted accordingly.

Assets and Liabilities Not Measured at Fair Value

For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate, are assumed to have a fair value that approximates the reported book value, after taking into consideration any applicable credit risk. If no market quotes are available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument. For loans held for investment, fair value is measured using the exit price notion. For off-balance sheet derivative instruments, fair value is estimated as the amount that Atlantic Capital would receive or pay to terminate the contracts at the reporting date, taking into account the current unrealized gains or losses on open contracts.

The short maturity of Atlantic Capital’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest-bearing deposits in other banks, other short-term investments, and FHLB stock. The fair value of securities equals quoted market prices, if available.  If a quoted market price is not available, fair value is estimated used quoted market prices for similar securities or dealer quotes. Due to the short-term settlement of accrued interest receivable and payable, the carrying amount closely approximates fair value.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect the premium or discount on any particular financial instrument that could result from the sale of Atlantic Capital’s entire holdings. Because no ready market exists for a significant portion of Atlantic Capital’s financial instruments, fair value estimates are based on many judgments. These estimates are subjective in nature, involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Off-balance sheet financial instruments (commitments to extend credit and standby letters of credit) are generally short-term and at variable rates. Therefore, both the carrying amount and the estimated fair value associated with these instruments are immaterial.

The following table presents the estimated fair values of Atlantic Capital’s financial instruments at September 30, 2019 and December 31, 2018.

Earnings Per Common Share

NOTE 10 – EARNINGS PER COMMON SHARE

Basic earnings per share amounts are computed by dividing net income by the weighted average number of shares of common stock outstanding.

Diluted earnings per share amounts are computed by dividing net income by the weighted average number of shares of common stock outstanding and the dilutive effects of the shares awarded under the stock option plan, based on the treasury stock method using an average fair market value of the stock during the respective periods.

The following table represents the earnings per share calculations for the three and nine months ended September 30, 2019 and 2018.

⁽¹⁾ Unvested restricted shares are participating securities and included in basic share calculations.

Stock options outstanding of 150 at September 30, 2019 and 244 at September 30, 2018 have not been included in diluted earnings per share because to do so would have been anti-dilutive for the periods presented. These awards were considered anti-dilutive because the exercise price of the award was higher than the market value of the shares.

The Amended and Restated Articles of Incorporation of Atlantic Capital authorize Atlantic Capital to issue 110,000,000 shares of capital stock, of which 10,000,000 shares are designated as preferred stock, no par value per share, and 100,000,000 shares are designated as common stock, no par value per share. At September 30, 2019, 22,193,761 shares of common stock were issued and outstanding. At December 31, 2018, 25,290,419 shares of common stock were issued and outstanding.

The primary source of funds available to Atlantic Capital is payments of dividends from the Bank. The Bank paid dividends totaling $10.0 million and $36.5 million to Atlantic Capital during the three and nine months ended September 30, 2019. No dividends were paid by the Bank during the three or nine months ended September 30, 2018. During the fourth quarter of 2018, the Bank paid a dividend totaling $30.0 million. Banking laws and other regulations limit the amount of dividends a bank subsidiary may pay without prior regulatory approval. Additionally, Atlantic Capital’s ability to pay dividends to its shareholders will depend on the ability of the Bank to pay dividends to Atlantic Capital. The Bank is subject to regulatory restrictions on the payment of cash dividends, which generally may be paid only from current earnings.

On November 14, 2018, the Board of Directors authorized a stock repurchase program pursuant to which the Company may purchase up to $85 million of its issued and outstanding common stock. The timing and amounts of any repurchases depend on certain factors, including but not limited to market conditions and prices, available funds and alternative uses of capital. The stock repurchase program may be carried out through open-market purchases, block trades, negotiated private transactions and pursuant to a trading plan that was adopted in accordance with Rule 10b‑18 and Rule 10b5‑1 under the Securities Exchange Act of 1934. Atlantic Capital repurchased 1,164,063 and 3,242,579 shares during the three and nine months ended September 30, 2019 for a total of $20.1 million and $56.7 million, respectively. Since the announcement of the $85.0 million buyback program in November of 2018, Atlantic Capital has repurchased 4.1 million shares totaling $70.9 million.

At September 30, 2019 and December 31, 2018, loans with a carrying value of $689.0 million and $752.7 million, respectively, were pledged as collateral to secure Federal Home Loan Bank of Atlanta (“FHLB”) advances and the Federal Reserve discount window.

At December 31, 2018, PCI loans were designated as held for sale for the Branch Sale. The following table presents changes in the value of the accretable yield for acquired loans accounted for under ASC 310‑30 for the three and nine months ended September 30, 2019 and 2018.

	For the Three Months Ended				For the Nine Months Ended

Other changes, net		—		96		—		542
Balance at end of period	$	—	$	2,433	$	—	$	2,433

In addition to the accretable yield on PCI loans, the fair value adjustments on purchased loans outside the scope of ASC 310‑30 are also accreted to interest income over the life of the loans. At September 30, 2019, the remaining accretable fair value discount on loans acquired through a business combination and not accounted for under ASC 310‑30 was $324,000 compared to $3.6 million at December 31, 2018.

The allowance for loan losses represents management’s estimate of probable incurred losses in the loan portfolio as of the end of the period. It is comprised of specific reserves for impaired loans and a general allowance for pools of loans with similar characteristics not individually evaluated. The allowance is regularly evaluated to maintain an adequate level to absorb probable current inherent losses in the loan portfolio. Factors contributing to the determination of the allowance include the credit worthiness of the borrower, changes in the value of pledged collateral, and general economic conditions. Most loan commitments rated substandard or worse are specifically reviewed for loss potential. For loans deemed to be impaired, a specific allocation is assigned based on the losses expected to be realized from those loans.

The following table presents the balance and activity in the allowance for loan losses by portfolio segment for the three and nine months ended September 30, 2019 and 2018.

Atlantic Capital evaluates loans in accordance with ASC 310‑40, Troubled Debt Restructurings by Creditors. TDRs are loans in which Atlantic Capital has modified the terms or granted an economic concession to a borrower who is experiencing financial difficulties. These modifications may include interest rate reductions, term extensions and other concessions intended to minimize losses.

As of September 30, 2019, and December 31, 2018, the Company had a recorded investment in TDRs of $12.8 million and $8.2 million, respectively. The Company had commitments to lend additional funds of $3,000 and $28,000 on loans modified as TDRs, as of September 30, 2019 and December 31, 2018, respectively. During the three months ended September 30, 2019, the Company restructured via bankruptcy one commercial real estate SBA loan, resulting in its reclassification as a TDR. For the nine months ended September 30, 2019, restructurings included modifications such as payment deferrals and interest only forbearance.

Loans, by portfolio class, modified as TDRs during the three and nine months ended September 30, 2019 are as follows.

		Pre-Modification			Post-Modification
		Outstanding			Outstanding
	Number of Loans	Recorded Investment		Recorded Investment

Three Months Ended September 30, 2019
Commercial real estate	1	$	1,512	$	1,512

Commercial and industrial	6	$	1,235	$	1,235
Commercial real estate	3		2,438		2,438
Total	9	$	3,673	$	3,673

The Company did not forgive any principal on TDRs during the three and nine month periods ended September 30, 2019 and 2018, and there were no subsequent defaults of previously identified TDRs.

Atlantic Capital individually rates loans based on internal credit risk ratings using numerous factors, including thorough analysis of historical and expected cash flows, consumer credit risk scores (FICO scores), rating agency information, LTV ratios, collateral, collection experience, and other internal metrics. Atlantic Capital uses a dual rating system. The likelihood of default of a credit transaction is graded in the Obligor Rating. The risk of loss given default is graded in the Facility Rating. The Obligor Rating is determined through credit analysis. Facility Ratings are used to describe the value to the Company that the collateral represents. Facility Ratings are based on the collateral package or market expectations regarding the value and liquidity of the collateral. Ratings are generally reviewed at least annually or more frequently if there is a material change in creditworthiness. Exceptions to this policy may include well collateralized term loans and loans to individuals with limited exposure or complexity.

Atlantic Capital uses the following definitions for risk ratings:

Pass: Loans that are analyzed individually as part of the above described process and that do not meet the criteria of special mention, substandard or doubtful.

Special Mention: Loans classified as special mention have a potential weakness that requires 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 classified 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 classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

As of September 30, 2019 and December 31, 2018, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows. Total loans at December 31, 2018 includes loans held for sale - discontinued operations.

Accounting Standards Updates and Recently Adopted Standards

Accounting Standards Updates and Recently Adopted Standards

NOTE 2 – ACCOUNTING STANDARDS UPDATES AND RECENTLY ADOPTED STANDARDS

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016‑02, “Leases.” Under the new guidance, leases classified as operating leases under previous GAAP must be recorded on the balance sheet. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use (“ROU”) asset representing its right to use the underlying asset for the lease term. In July 2018, the FASB issued ASU No. 2018‑10, “Codification Improvements to Topic 842, Leases and ASU No. 2018‑11, Leases (Topic 842): Targeted Improvements.”  ASU No. 2018‑10 provides improvements related to ASU No. 2016‑02 to increase stakeholders’ awareness of the amendments and to expedite the improvements. The amendments affect narrow aspects of the guidance issued in ASU No. 2016‑02. ASU No. 2018‑11 allows entities adopting ASU No. 2016‑02 to choose an additional (and optional) transition method, under which an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The amendments in these updates became effective for the Company on January 1, 2019. The impact of adoption was recording a lease liability of approximately $18.9 million in other liabilities on the Consolidated Balance Sheets, a ROU asset of approximately $14.5 million in premises and equipment, and a cumulative effect adjustment to retained earnings, net of tax, of approximately $373,000.

Recently Issued Accounting Pronouncements Not Yet Adopted

In May 2019, the FASB issued ASU No. 2019‑05, “Financial Instruments - Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016‑13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of Accounting Standards Codification (“ASC”) 326‑20 if the instruments are eligible for the fair value option under ASC 825‑10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. ASU 2019‑05 has the same effective date as ASU 2016‑13 (i.e., the first quarter of 2020). The Company does not expect to elect the fair value option, and therefore, ASU 2019‑05 is not expected to impact the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018‑13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” The amendments in this update modify the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The update is effective for interim and annual periods in fiscal years beginning after December 31, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for new disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The adoption will not have a material effect on the Company’s consolidated financial statements.

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.” This guidance shortens the premium amortization period for certain callable debt securities by requiring amortization to the earliest call date. The standard is effective for public companies for annual and interim periods beginning after December 15, 2020. The adoption of this update is not expected to have a material impact on Atlantic Capital’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which intends to simplify goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The update instead requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017‑04 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. Atlantic Capital does not expect the new guidance to have a material impact on its financial condition or results of operations.

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 an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016‑13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. ASU 2016‑13 is effective for public companies for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is implementing a software package supported by a third-party vendor. The Company’s CECL working group is meeting regularly with a CECL Management Group and the Company’s Board of Directors to discuss implementation progress and methodology selections. Progress has been made on life-of-loan loss calculations and on economic forecasting methods that will be utilized in the modeling process. The Company continues to refine its new methodology leading up to the adoption of the ASU and will continue to evaluate the impact of the adoption on the Company’s consolidated financial statements and disclosures.
