Accounting Policies and Basis of Presentation	ACCOUNTING POLICIES AND 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 filing 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.

Accounting Policies [Abstract]
Accounting Standards Updates and Recently Adopted Standards	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 will perform parallel runs of its new methodology in 2019 prior to adoption of the ASU. Atlantic Capital is continuing to evaluate the impact of the adoption of ASU 2016-13 on the Company’s consolidated financial statements and disclosures.

Discontinued Operations and Disposal Groups [Abstract]
Acquisitions and Divestitures	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 six months ended June 30, 2019 and 2018, are included in discontinued operations and prior period financial information has been retrospectively adjusted for the impact of discontinued operations.

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 June 30, 2019 , there were 127 available-for-sale 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 June 30, 2019 and December 31, 2018 were attributable to changes in interest rates. No impairment charges on securities available-for-sale were recognized during the six months ended June 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 six months ended June 30, 2019 and 2018 . Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 (in thousands) Proceeds from sales $ 54,938 $ 24 $ 54,938 $ 24 Gross realized gains 1,122 — 1,122 — Gross realized losses (468 ) (2 ) (468 ) (2 ) Net gains (losses) on sales of securities $ 654 $ (2 ) $ 654 $ (2 ) Investment securities with a carrying value of $25.2 million and $65.3 million were pledged to secure public funds and other borrowings at June 30, 2019 and December 31, 2018 , respectively. As of June 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 second quarter of 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.

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 six months ended June 30, 2019 and 2018. For the Three Months Ended For the Six Months Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 (in thousands) Balance at beginning of period $ — $ 2,409 $ — $ 2,316 Accretion — (301 ) — (599 ) Reclassification of nonaccretable discount due to change in expected cash flows — 197 — 293 Other changes, net — 151 — 446 Balance at end of period $ — $ 2,456 $ — $ 2,456 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 June 30, 2019 , the remaining accretable fair value discount on loans acquired through a business combination and not accounted for under ASC 310-30 was $337,000 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 credit losses by portfolio segment for the three and six months ended June 30, 2019 and 2018 . 2019 2018 Three Months Ended June 30, Commercial Residential Consumer Total Commercial Residential Consumer Total (in thousands) Allowance for loan losses: Beginning balance $ 17,397 $ 447 $ 263 $ 18,107 $ 18,797 $ 828 $ 260 $ 19,885 Provision for loan losses 1,055 (283 ) (74 ) 698 (283 ) 85 25 (173 ) Loans charged-off (635 ) — — (635 ) (50 ) (102 ) (10 ) (162 ) Recoveries — — 16 16 27 — 6 33 Total ending allowance balance $ 17,817 $ 164 $ 205 $ 18,186 $ 18,491 $ 811 $ 281 $ 19,583 2019 2018 Six Months Ended June 30, Commercial Residential Consumer Total Commercial Residential Consumer Total (in thousands) Allowance for loan losses: Beginning balance $ 17,322 $ 292 $ 237 $ 17,851 $ 18,267 $ 802 $ 275 $ 19,344 Provision for loan losses 1,662 (127 ) (23 ) 1,512 354 239 6 599 Loans charged-off (1,184 ) (9 ) (37 ) (1,230 ) (176 ) (230 ) (13 ) (419 ) Recoveries 17 8 28 53 46 — 13 59 Total ending allowance balance $ 17,817 $ 164 $ 205 $ 18,186 $ 18,491 $ 811 $ 281 $ 19,583 The general component of the allowance for loan losses is based on the incurred losses inherent in the portfolio. The loss factors are determined through the generation of probabilities of default (“PDs”) and losses given default (“LGDs”) for groups of similar loans with similar credit grades where Loss Rate = PD x LGD. The PDs and LGDs for the loan portfolio are calculated based on Atlantic Capital’s loss history as well as available market-based data. The loss factor for each pool of loans is adjusted based on qualitative and environmental factors to account for conditions in the current environment which management believes are likely to cause a difference between the calculated loss based on historical performance and the incurred loss in the existing portfolio. These factors include: changes in policies and procedures, changes in the economy, changes in nature or volume of the portfolio and in the terms of loans, changes in lending management, changes in past dues and credit migration, changes in the loan review system, changes in the value of collateral and concentration risk and changes in external factors, such as competition, legal and regulatory. Quarterly, management evaluates these factors to determine an adjustment unique to Atlantic Capital and its market. Charge-offs are recognized when the amount of the loss is quantifiable and timing is known. Collateral based loan charge-offs are measured based on the difference between the loan’s carrying value, including deferred fees, and the estimated net realizable value of the loan. When assessing property value for the purpose of determining a charge-off, a third-party appraisal or an independently derived internal evaluation is generally employed. A loan is considered to be impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Loans for which the terms have been modified or granted an economic concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (“TDRs”) and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. A specific allowance is established for individually evaluated impaired loans as needed. Reserves on impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the observable market price, or the fair value of the underlying collateral of the loan if the loan is collateral dependent. Atlantic Capital’s policy is to place loans on nonaccrual status, when, in the opinion of management, the principal and interest on a loan are not likely to be repaid in accordance with the loan terms or when the loan becomes 90 days past due and is not both well secured and in the process of collection. When a loan is classified on nonaccrual status, interest previously accrued but not collected is reversed against current interest revenue. Principal and interest payments received on a nonaccrual loan are applied to reduce outstanding principal. The balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method is presented in the following table as of June 30, 2019 and December 31, 2018 .

These modifications may include interest rate reductions, term extensions and other concessions intended to minimize losses. As of June 30, 2019 and December 31, 2018 , the Company had a recorded investment in TDRs of $9.2 million and $8.2 million , respectively. The Company had commitments to lend additional funds of $0 and $28,000 on loans modified as TDRs, as of June 30, 2019 and December 31, 2018 , respectively. During the three months ended June 30, 2019 , the Company extended the amortization period for one commercial and industrial SBA loan, resulting in its reclassification as a TDR. Additionally, during the three months ended June 30, 2019 , the Company restructured two commercial and industrial SBA loans to lower the payment amounts, resulting in their reclassification as TDRs. During the six months ended June 30, 2019 , the Company granted payment deferrals on four SBA loans, three classified as commercial and industrial and one classified as commercial real estate, resulting in their reclassification as TDRs. During the same period, the Company granted an interest only forbearance on one commercial real estate loan to allow time for the pledged collateral to sell. This concession resulted in the reclassification of this loan as a TDR. The Company did not modify any loans as TDRs during the three and six months ended June 30, 2018. Loans, by portfolio class, modified as TDRs during the three and six months ended June 30, 2019 are as follows.

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 June 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.

Servicing Assets	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 June 30, 2019 and December 31, 2018 , the balance of SBA loans sold and serviced by Atlantic Capital totaled $175.9 million and $161.5 million , respectively. Changes in the balance of servicing assets for the three and six months ended June 30, 2019 and 2018 are presented in the following table .

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.

Earnings Per Share [Abstract]
Earnings Per Common Share	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 six months ended June 30, 2019 and 2018 . Three Months Ended Six Months Ended June 30, June 30, 2019 2018 2019 2018 (in thousands, except share and per share amounts) Net income from continuing operations $ 7,009 $ 8,378 $ 13,449 $ 13,569 Net income (loss) from discontinued operations 22,143 (227 ) 21,080 (380 ) Net income available to common shareholders $ 29,152 $ 8,151 $ 34,529 $ 13,189 Weighted average shares outstanding Basic (1) 23,888,381 26,010,914 24,369,106 25,881,587 Effect of dilutive securities: Stock options, warrants and performance share awards 152,425 189,112 158,286 192,015 Diluted 24,040,806 26,200,026 24,527,392 26,073,602 Net income (loss) per common share - basic Net income per common share - continuing operations $ 0.29 $ 0.32 $ 0.55 $ 0.52 Net income (loss) per common share - discontinued operations 0.93 (0.01 ) 0.87 (0.01 ) Net income per common share - basic 1.22 0.31 1.42 0.51 Net income (loss) per common share - diluted Net income per common share - continuing operations $ 0.29 $ 0.32 $ 0.55 $ 0.52 Net income (loss) per common share - discontinued operations 0.92 (0.01 ) 0.86 (0.01 ) Net income per common share - diluted 1.21 0.31 1.41 0.51 (1) Unvested restricted shares are participating securities and included in basic share calculations. Stock options outstanding of 150 at June 30, 2019 and 244 at June 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 June 30, 2019 , 23,293,465 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 $26.5 million to Atlantic Capital during the three and six months ended June 30, 2019 . No dividends were paid by the Bank during the three or six months ended June 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 1,121,221 and 2,078,516 shares during the three and six months ended June 30, 2019 for a total of $19.5 million and $36.6 million , respectively. Since the announcement of the $85.0 million buyback program in November of 2018, Atlantic Capital has repurchased 2.9 million shares totaling $50.8 million .

Derivatives and Hedging

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	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 June 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 June 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 six months ended June 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 $24,000 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 June 30, 2019 and December 31, 2018 , Atlantic Capital had interest rate swaps related to this program with an aggregate notional amount of $93.8 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 June 30, 2019 and December 31, 2018 , Atlantic Capital had interest rate swaps related to this program with an aggregate notional amount of $152.7 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 June 30, 2019 and December 31, 2018 , Atlantic Capital had minimum collateral posting thresholds with certain of its derivative counterparties and posted collateral of $5.9 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.

Share-Based Compensation

Share-Based Compensation	6 Months Ended

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	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 June 30, 2019 , approximately 3,379,000 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 six months ended June 30, 2019 and 2018: For the six months ended June 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 six months ended June 30, 2019 : Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding, December 31, 2018 442,454 $ 12.02 Granted/modified (1) 12,500 10.00 Exercised (41,920 ) 11.48 Forfeited (1) (38,500 ) 13.17 Expired (7,594 ) 12.43 Outstanding, June 30, 2019 366,940 $ 11.87 2.59 $ 1,934 Exercisable, June 30, 2019 346,940 $ 11.69 2.37 $ 1,891 (1) During the six months ended June 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 $52,000 and $133,000 for the three and six months ended June 30, 2019 , respectively, and $40,000 and $98,000 for the three and six months ended June 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 six months ended June 30, 2019 : Shares Weighted Average Grant-Date Fair Value Outstanding, December 31, 2018 272,695 $ 18.09 Granted/modified (1) 130,093 19.54 Exercised (64,011 ) 16.54 Forfeited (1) (65,750 ) 18.38 Outstanding, June 30, 2019 273,027 $ 19.07 (1) During the six months ended June 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 June 30, 2019 and 2018, compensation expense of $216,000 and $413,000 , respectively, was recognized related to restricted stock and performance share awards. For the six months ended June 30, 2019 and 2018, compensation expense of $707,000 and $814,000 , respectively, was recognized related to restricted stock and performance share awards. As of June 30, 2019 , there was $ 2.4 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 2.17 years. During the six months ended June 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 termination of service. The total incremental cost resulting from the modifications was $31,000 for the six months ended June 30, 2019.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	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 six months ended June 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. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents the assets that were measured at fair value on a recurring basis by level within the fair value hierarchy as reported in the Consolidated Balance Sheets at June 30, 2019 and December 31, 2018 .

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 June 30, 2019 and December 31, 2018 . June 30, 2019 Level 1 Fair Value Measurement Level 2 Fair Value Measurement Level 3 Fair Value Measurement Total (in thousands) Impaired Loans $ — $ — $ 1,842 $ 1,842 SBIC Investments — — 4,433 4,433 Totals $ — $ — $ 6,275 $ 6,275 December 31, 2018 Level 1 Fair Value Measurement Level 2 Fair Value Measurement Level 3 Fair Value Measurement Total (in thousands) 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 available-for-sale equals the balance sheet value. 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 and 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 June 30, 2019 and December 31, 2018 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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 June 30, 2019 and December 31, 2018 was as follows: June 30, December 31, (in thousands) Financial Instruments whose contract amount represents credit risk: Commitments to extend credit $ 628,801 $ 715,591 Standby letters of credit 8,758 15,650 $ 637,559 $ 731,241 Minimum lease payments $ 17,220 $ 22,014 The Company also had commitments related to investments in SBICs totaling $2.9 million and $3.2 million at June 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.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	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 also 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 six months ended June 30, 2019 and 2018: For the Three Months Ended June 30, For the Six Months Ended June 30, 2019 2018 2019 2018 (in thousands) Deposit account analysis fees and charges $ 676 $ 550 $ 1,222 $ 1,036 ATM fees (8 ) 56 39 106 NSF fees 8 28 22 66 Wire fees 102 102 212 193 Foreign exchange fees 92 89 165 126 Other — 3 4 8 Total service charges - continuing operations 870 828 1,664 1,535 Service charges - discontinued operations 46 480 527 965 Total service charges $ 916 $ 1,308 $ 2,191 $ 2,500 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 six months ended June 30, 2018 : For the Three Months Ended June 30, For the Six Months Ended June 30, 2019 2018 2019 2018 (in thousands) Personal trust and agency accounts $ — $ 303 $ — $ 616 Employee benefit and retirement-related trust and agency accounts — 60 — 120 Investment management and investment advisory agency accounts — 110 — 217 Custody and safekeeping accounts — 13 — 26 Other — 21 — 46 $ — $ 507 $ — $ 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 June 30, 2019 and December 31, 2018 , the Company did not have any significant contract balances.

Leases [Abstract]
Leases	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 June 30, 2019 , operating lease ROU assets and liabilities were $10.4 million and $14.4 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 Six Months Ended June 30, 2019 June 30, 2019 (in thousands) Operating lease cost $ 461 $ 1,126 Short-term lease cost 12 26 Sublease income (42 ) (116 ) Net lease cost $ 431 $ 1,036 The tables below summarize other information related to the Company’s operating leases: Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 (in thousands) Operating cash paid for amounts included in the measurement of lease liabilities $ 522 $ 1,043 Right-of-use assets obtained in exchange for new finance lease liabilities 716 15,207 June 30, 2019 Weighted-average remaining lease term - operating leases 9.2 years Weighted-average discount rate - operating leases 3.3 % The table below summarizes the maturity of remaining lease liabilities: June 30, 2019 Twelve Months Ended: (in thousands) June 30, 2020 $ 2,227 June 30, 2021 1,886 June 30, 2022 1,935 June 30, 2023 1,780 June 30, 2024 1,523 Thereafter 7,869 Total future minimum lease payments 17,220 Less: Interest (2,777 ) Present value of net future minimum lease payments $ 14,443 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 six 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 filing 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 will perform parallel runs of its new methodology in 2019 prior to adoption of the ASU. Atlantic Capital is continuing to evaluate the impact of the adoption of ASU 2016-13 on the Company’s consolidated financial statements and disclosures.
