BASIS OF PRESENTATION AND ACCOUNTING POLICIES
NOTE 1 – BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Nature of Business

Ameris Bancorp (the “Company” or “Ameris”) is a financial holding company headquartered in Atlanta, Georgia. Ameris conducts substantially all of its operations through its wholly owned banking subsidiary, Ameris Bank (the “Bank”). At June 30, 2023, the Bank operated 164 branches in select markets in Georgia, Alabama, Florida, North Carolina and South Carolina. Our business model capitalizes on the efficiencies of a large financial services company, while still providing the community with the personalized banking service expected by our customers. We manage our Bank through a balance of decentralized management responsibilities and efficient centralized operating systems, products and loan underwriting standards. The Company’s Board of Directors and senior managers establish corporate policy, strategy and administrative policies. Within our established guidelines and policies, the banker closest to the customer responds to the differing needs and demands of his or her unique market.

Basis of Presentation

The accompanying unaudited consolidated financial statements for Ameris have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statement presentation. The interim consolidated financial statements included herein are unaudited but reflect all adjustments, consisting of normal recurring adjustments, which, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the interim periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from banks, interest-bearing deposits in banks, federal funds sold and restricted cash. There was no restricted cash held at both June 30, 2023 and December 31, 2022.

Reclassifications

Certain reclassifications of prior year amounts have been made to conform with the current year presentations. The reclassifications had no effect on net income or shareholders' equity as previously reported.

Accounting Standards Adopted in 2023

ASU No. 2022-02 – Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). ASU 2022-02 eliminates the troubled debt restructuring ("TDR") measurement and recognition guidance and requires that entities evaluate whether the modification represents a new loan or a continuation of an existing loan consistent with the accounting for other loan modifications. Additional disclosures relating to modifications to borrowers experiencing financial difficulty are required under ASU 2022-02. ASU 2022-02 also requires disclosure of current-period gross write-offs by year of origination. The Company adopted this ASU effective January 1, 2023 on a prospective basis, except for the amendments related to recognition and measurement of TDRs, which were adopted using the modified retrospective method. The adoption was not material and resulted in a reduction to the allowance for credit losses of $1.7 million and an increase to retained earnings of $1.3 million.
ASU No. 2022-06 - Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU No. 2022-06 extends the temporary relief in Topic 848 from December 31, 2022 to December 31, 2024. Topic 848 provides optional guidance to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The objective of this guidance is to provide temporary relief during the transition period away from LIBOR toward new interest rate benchmarks. This update was effective upon issuance. The Company adopted the guidance in Topic 848 effective January 1, 2023 and the adoption was not material the consolidated financial statements.

As of June 30, 2023, the Company’s held-to-maturity security portfolio consisted of 27 securities, all of which were in an unrealized loss position. At June 30, 2023, the Company held 21 mortgage-backed securities and six state, county and municipal securities that were in an unrealized loss position.

At June 30, 2023 and December 31, 2022, all of the Company’s mortgage-backed securities were obligations of government-sponsored agencies.

Management and the Company’s Asset and Liability Committee (the “ALCO Committee”) evaluate available-for-sale securities in an unrealized loss position on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation, to determine if credit-related impairment exists. Management first evaluates whether they intend to sell or more likely than not will be required to sell an impaired security before recovering its amortized cost basis. If either criteria is met, the entire amount of unrealized loss is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. If either of the above criteria is not met, management evaluates whether the decline in fair value is attributable to credit or resulted from other factors. The Company does not intend to sell these available-for-sale investment securities at an unrealized loss position at June 30, 2023, and it is more likely than not that the Company will not be required to sell these securities prior to recovery or maturity. Based on the results of management's review, at June 30, 2023, management determined that $82,000 was attributable to credit impairment and an allowance for credit losses was recorded. The remaining $64.4 million in unrealized loss was determined to be from factors other than credit.

Accrued interest receivable on loans is reported in other assets on the consolidated balance sheets totaling $69.8 million and $69.3 million at June 30, 2023 and December 31, 2022, respectively. The Company had no recorded allowance for credit related to accrued interest on loans at both June 30, 2023 and December 31, 2022.

Nonaccrual and Past-Due Loans

A loan is placed on nonaccrual status when, in management’s judgment, the collection of the interest income appears doubtful. Interest receivable that has been accrued and is subsequently determined to have doubtful collectability is charged to interest income. Interest on loans that are classified as nonaccrual is subsequently applied to principal until the loans are returned to accrual status. The Company’s loan policy states that a nonaccrual loan may be returned to accrual status when (i) none of its principal and interest is due and unpaid, and the Company expects repayment of the remaining contractual principal and interest, or (ii) it otherwise becomes well secured and in the process of collection. Restoration to accrual status on any given loan must be supported by a well-documented credit evaluation of the borrower’s financial condition and the prospects for full repayment, approved by the Company’s Chief Credit Officer. Past-due loans are loans whose principal or interest is past due 30 days or more. In some cases, where borrowers are experiencing financial difficulties, loans may be restructured to provide terms significantly different from the original contractual terms.

The following table presents an analysis of loans accounted for on a nonaccrual basis:

Collateral-Dependent Loans

Collateral-dependent loans are loans where repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. If the Company determines that foreclosure is probable, these loans are written down to the lower of cost or fair value of the collateral less estimated costs to sell. When repayment is expected to be from the operation of the collateral, the allowance for credit losses is calculated as the amount by which the amortized cost basis of the financial asset exceeds the present value of expected cash flows from the operation of the collateral. The Company may, in the alternative, measure the allowance for credit loss as the amount by which the amortized cost basis of the financial asset exceeds the estimated fair value of the collateral.
The following table presents an analysis of individually evaluated collateral-dependent financial assets and related allowance for credit losses:

Credit Quality Indicators

The Company uses a nine category risk grading system to assign a risk grade to each loan in the portfolio. The following is a description of the general characteristics of the grades:

Pass (Grades 1 - 5) – These grades represent acceptable credit risk to the Company based on factors including creditworthiness of the borrower, current performance and nature of the collateral.

Other Assets Especially Mentioned (Grade 6) – This grade includes loans that exhibit potential weaknesses that deserve management’s close attention. If left uncorrected, these weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date.

Substandard (Grade 7) – This grade represents loans which are inadequately protected by the current credit worthiness and paying capacity of the borrower or of the collateral pledged, if any. These assets exhibit a well-defined weakness or are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. These weaknesses may be characterized by past due performance, operating losses or questionable collateral values.

Doubtful (Grade 8) – This grade includes loans which exhibit all of the characteristics of a substandard loan with the added provision that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable or improbable.

Loss (Grade 9) – This grade is assigned to loans which are considered uncollectible and of such little value that their continuance as active assets of the Bank is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing it off.

The following tables present the loan portfolio's amortized cost by class of financing receivable, risk grade and year of origination (in thousands) as of June 30, 2023 and December 31, 2022. Generally, current period renewals of credit are underwritten again at the point of renewal and considered current period originations for purposes of the tables below. The Company had an immaterial amount of revolving loans which converted to term loans and the amortized cost basis of those loans is included in the applicable origination year. There were no loans risk graded 8 or 9 at June 30, 2023 or December 31, 2022.

Allowance for Credit Losses on Loans

The allowance for credit losses represents an allowance for expected losses over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications. The Company segregates the loan portfolio by type of loan and utilizes this segregation in evaluating exposure to risks within the portfolio.

Loan losses are charged against the allowance when management believes the collection of a loan’s principal is unlikely. Subsequent recoveries are credited to the allowance. Consumer loans are charged off in accordance with the Federal Financial Institutions Examination Council’s (the “FFIEC”) Uniform Retail Credit Classification and Account Management Policy. Commercial loans are charged off when they are deemed uncollectible, which usually involves a triggering event within the collection effort. If the loan is collateral dependent, the loss is more easily identified and is charged off when it is identified, usually based upon receipt of an appraisal. However, when a loan has guarantor support, the Company may carry the estimated loss as a reserve against the loan while collection efforts with the guarantor are pursued. If, after collection efforts with the guarantor are complete, the deficiency is still considered uncollectible, the loss is charged off and any further collections are treated as recoveries. In all situations, when a loan is downgraded to an Asset Quality Rating of 9 (Loss per the regulatory guidance), the uncollectible portion is charged off.

The Company’s methodologies for estimating the allowance for credit losses consider available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The methodologies apply historical loss information, adjusted for asset-specific characteristics, economic conditions at the measurement date, and forecasts about future economic conditions expected to exist through the contractual lives of the financial assets that are reasonable and supportable, to the identified pools of loans with similar risk characteristics for which the historical loss experience was observed. The Company utilizes a one year reasonable and supportable forecast period. The Company’s methodologies revert back to historical loss information on a straight-line basis over four quarters after the reasonable and supportable forecast period.

During the six months ended June 30, 2023, the allowance for credit losses increased due to a decline in forecasted macroeconomic factors, particularly residential and commercial real estate price indices and organic loan growth during the period. The allowance for credit losses was determined at June 30, 2023 using a weighting of two economic forecasts from Moody's in order to align with management's best estimate over the reasonable and supportable forecast period. The Moody's baseline scenario was weighted at 75% and the upside 10th percentile S-1 scenario was weighted at 25%. The allowance for
credit losses was determined at December 31, 2022 solely using the Moody's baseline scenario economic forecast. The current forecast reflects, among other things, declines in forecast levels of home prices and commercial real estate prices compared with the forecast at December 31, 2022.

The following tables detail activity and end of period balances in the allowance for credit losses by portfolio segment for the periods indicated. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

Modifications to Borrowers Experiencing Financial Difficulty

The Company periodically provides modifications to borrowers experiencing financial difficulty. These modifications include either payment deferrals, term extensions, interest rate reductions, principal forgiveness or combinations of modification types. The determination of whether the borrower is experiencing financial difficulty is made on the date of the modification. When principal forgiveness is provided, the amount of principal forgiveness is charged off against the allowance for credit losses with a corresponding reduction in the amortized cost basis of the loan.

The following table shows the amortized cost basis of the loans modified to borrowers experiencing financial difficulty, disaggregated by class of financing receivable and type of concession granted:

Fair Value Disclosures [Abstract]  
FAIR VALUE MEASURES
NOTE 7 – FAIR VALUE MEASURES

The fair value of an asset or liability is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various assets and liabilities. In cases where quoted market prices are not available, fair value is based on discounted cash flows or other valuation techniques. These techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the asset or liability. The accounting standard for disclosures about the fair value measures excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.

The Company's loans held for sale under the fair value option are comprised of the following:

(dollars in thousands)June 30, 2023December 31, 2022
Mortgage loans held for sale$391,212 $390,583 
SBA loans held for sale260 1,495 
Total loans held for sale$391,472 $392,078 

The Company has elected to record mortgage loans held for sale at fair value in order to eliminate the complexities and inherent difficulties of achieving hedge accounting and to better align reported results with the underlying economic changes in value of the loans and related hedge instruments. This election impacts the timing and recognition of origination fees and costs, as well as servicing value, which are now recognized in earnings at the time of origination. Interest income on mortgage loans held for sale is recorded on an accrual basis in the consolidated statements of income and comprehensive income under the heading interest income – interest and fees on loans. The servicing value is included in the fair value of the interest rate lock commitments (“IRLCs”) with borrowers. The mark to market adjustments related to mortgage loans held for sale and the associated economic hedges are captured in mortgage banking activities.

A net loss of $3.3 million and a net gain of $2.3 million resulting from changes in fair value of these mortgage loans were recorded in income during the three and six months ended June 30, 2023, respectively. For the three and six months ended June 30, 2022, a net gain of $11.2 million and a net loss of $32.7 million, respectively, resulting from changes in fair value of these mortgage loans were recorded in income. Net gains of $7.9 million and $5.1 million resulting from changes in the fair value of the related derivative financial instruments used to hedge exposure to the market-related risks associated with these mortgage loans were recorded in income during the three and six months ended June 30, 2023, respectively. For the three and six months ended June 30, 2022, net losses of $27.1 million and $1.2 million, respectively, resulting from changes in the fair value of the related derivative financial instruments were recorded in income. The changes in fair value of both mortgage loans held for sale and the related derivative financial instruments are recorded in mortgage banking activity in the consolidated statements of income and comprehensive income. The Company’s valuation of mortgage loans held for sale incorporates an assumption for credit risk; however, given the short-term period that the Company holds these loans, valuation adjustments attributable to instrument-specific credit risk is nominal.

The following table summarizes the difference between the fair value and the principal balance for mortgage loans held for sale measured at fair value as of June 30, 2023 and December 31, 2022:

The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale, loans held for sale under the fair value option and derivative financial instruments are recorded at fair value on a recurring basis. From time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as collateral-dependent loans, loan servicing rights and OREO. Additionally, the Company is required to disclose, but not record, the fair value of other financial instruments.

The following table presents the fair value measurements of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall as of June 30, 2023 and December 31, 2022:

COMMITMENTS AND CONTINGENCIES
NOTE 8 – COMMITMENTS AND CONTINGENCIES

Loan Commitments

The Company 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 standby letters of credit. They involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amount recognized in the Company’s balance sheets.

The Company’s exposure to credit loss is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. A summary of the Company’s commitments is as follows:

(dollars in thousands)June 30, 2023December 31, 2022
Commitments to extend credit$5,398,013 $6,318,039 
Unused home equity lines of credit376,944 345,001 
Financial standby letters of credit39,096 33,557 
Mortgage interest rate lock commitments302,208 148,148 

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments, predominantly at variable interest rates, generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral
obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Collateral is required in instances which the Company deems necessary. The Company has not been required to perform on any material financial standby letters of credit and the Company has not incurred any losses on financial standby letters of credit for the six months ended June 30, 2023 and the year ended December 31, 2022.

The Company maintains an allowance for credit losses on unfunded commitments which is recorded in other liabilities on the consolidated balance sheets. The following table presents activity in the allowance for unfunded commitments for the periods presented:

Other Commitments

As of June 30, 2023, letters of credit issued by the FHLB totaling $900.0 million were used to guarantee the Bank’s performance related to a portion of its public fund deposit balances.

Litigation and Regulatory Contingencies

The Company has been involved in various legal proceedings with William J. Villari, who formerly owned US Premium Finance Holding Company (“USPF”), a provider of commercial insurance premium finance loans that the Company acquired in January 2018. First, on December 13, 2018, Mr. Villari filed a demand for arbitration, claiming that the Bank’s termination of his employment for “cause” was improper and that he was entitled to additional compensation from the Company and the Bank under his employment agreement. Second, on December 28, 2018, Mr. Villari and his wholly owned company, P1 Finance Holdings LLC (“P1”), filed a lawsuit against the Bank in Broward County, Florida, seeking additional compensation for his service while an employee, as well as other relief. Third, on May 30, 2019, CEBV LLC (“CEBV”), which also is wholly owned by Mr. Villari, filed a lawsuit against the Bank in Duval County, Florida, arising out of a loan purchase agreement with the Bank dated May 8, 2018. CEBV’s complaint in that lawsuit, which also named as a defendant the Company’s former Chief Executive Officer, Dennis J. Zember Jr., sought unspecified damages and other relief related to asserted claims for fraudulent inducement and breach of contract based on the Bank’s alleged failure to provide sufficient assistance to CEBV in collecting on loans purchased by CEBV from the Bank. In addition, on January 30, 2019, the Company and the Bank filed a lawsuit against Mr. Villari in Dekalb County, Georgia, asserting claims for unspecified damages arising from Mr. Villari’s alleged failure to disclose material information in connection with the sale of USPF to the Company and the Bank.

In the first of these proceedings to be adjudicated, the Company and the Bank received on November 20, 2019, an Order and Award from the American Arbitration Association in which the arbitrator ruled that the Company and the Bank had cause to terminate Mr. Villari and had properly exercised that right and that, as a result, Mr. Villari is not entitled to any additional payments under his employment agreement or a separate management and licensing agreement with the Bank.

On April 24, 2023, all parties to the remaining cases entered into a settlement and release agreement resolving all remaining disputes between them. Subsequently all pending actions and claims concerning those cases were dismissed with prejudice. The terms of the parties’ settlement do not have a material adverse effect on the consolidated results of operations or financial condition of the Company.

Additionally, from time to time, the Company and the Bank are subject to various legal proceedings, claims and disputes that arise in the ordinary course of business. The Company and the Bank are also subject to regulatory examinations, information gathering requests, inquiries and investigations in the ordinary course of business. Based on the Company’s current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal and regulatory matters will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.
However, it is possible that the ultimate resolution of these legal and regulatory matters could have a material adverse effect on the Company’s results of operations and financial condition for any particular period.

The Company’s management and its legal counsel periodically assess contingent liabilities, which may result in a loss to the Company but which will only be resolved when one or more future events occur or fail to occur, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company or unasserted claims that may result in such proceedings, the Company evaluates the perceived merits of any legal proceedings or unasserted claims, as well as the perceived merits of the amount of relief sought or expected to be sought therein. If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Company’s financial statements. If the assessment indicates that a potentially material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the nature of the guarantee would be disclosed.

Transfers and Servicing [Abstract]  
LOAN SERVICING RIGHTS
NOTE 10 – LOAN SERVICING RIGHTS

The Company sells certain residential mortgage loans and SBA loans to third parties. All such transfers are accounted for as sales and the continuing involvement in the loans sold is limited to certain servicing responsibilities. The Company has also acquired servicing portfolios of residential mortgage and SBA loans. Loan servicing rights are initially recorded at fair value and subsequently recorded at the lower of cost or fair value and are amortized over the remaining service life of the loans, with consideration given to prepayment assumptions. Loan servicing rights are recorded in other assets on the consolidated balance sheets.

The carrying value of the loan servicing rights assets is shown in the table below:

Residential Mortgage Loans

The Company sells certain first-lien residential mortgage loans to third party investors, primarily the Federal National Mortgage Association (“FNMA”), the Government National Mortgage Association (“GNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”). The Company retains the related mortgage servicing rights (“MSRs”) and receives servicing fees on certain of these loans. The net gain on loan sales, MSRs amortization and recoveries/impairment, and ongoing servicing fees on the portfolio of loans serviced for others are recorded in the consolidated statements of income and comprehensive income as part of mortgage banking activity.

During the three- and six-months ended June 30, 2023, the Company recorded servicing fee income of $15.0 million and $29.2 million, respectively. During the three- and six-months ended June 30, 2022, the Company recorded servicing fee income of $18.9 million and $36.3 million, respectively. Servicing fee income includes servicing fees, late fees and ancillary fees earned for each period.
The table below is an analysis of the activity in the Company’s MSRs and valuation allowance:

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

SBA Loans

All sales of SBA loans, consisting of the guaranteed portion, are executed on a servicing retained basis. These loans, which are partially guaranteed by the SBA, are generally secured by business property such as real estate, inventory, equipment and accounts receivable. The net gain on SBA loan sales, amortization and impairment/recoveries of servicing rights, and ongoing servicing fees are recorded in the consolidated statements of income and comprehensive income as part of other noninterest income.
During the three- and six-months ended June 30, 2023, the Company recorded servicing fee income of $758,000 and $1.5 million, respectively. During the three- and six-months ended June 30, 2022, the Company recorded servicing fee income of $1.0 million and $1.9 million, respectively. Servicing fee income includes servicing fees, late fees and ancillary fees earned for each period.

Goodwill and Intangible Assets Disclosure [Abstract]  
GOODWILL GOODWILL
The Company has goodwill at its Banking Division and Premium Finance Division (collectively "the divisions"). The carrying value of goodwill at the Banking Division was $951.1 million at both June 30, 2023 and December 31, 2022. The carrying value of goodwill at the Premium Finance Division was $64.5 million at both June 30, 2023 and December 31, 2022. The Company performs its annual impairment test at December 31 of each year and more frequently if a triggering event occurs. At December 31, 2022, the Company performed a qualitative assessment of goodwill at the divisions and determined it was more likely than not that, in each case, the reporting unit's fair value exceeded its carrying value. The Company performed an interim qualitative assessment at March 31, 2023 considering the decline in the Company's stock price relative to book value and the impact of recent bank failures on the economy and again determined that it was more likely than not that each reporting unit's fair value exceeded its carrying value.

During the second quarter of 2023, the Company assessed the indicators of goodwill impairment and determined a triggering event had occurred due to the sustained decline in the Company's stock price. The Company performed a quantitative analysis of goodwill at the divisions as of June 30, 2023. The Premium Finance Division was measured utilizing a discounted cash flow approach. The Banking Division was measured using multiple approaches. The primary approach for the Banking Division was the discounted cash flow approach, and the Company also used a market approach comparing to similar public companies' multiples and control premiums from transactions during prior distressed periods. The results from each of the primary approaches showed valuation of the reporting unit in excess of carrying value at June 30, 2023. The discounted cash flow approach for the Premium Finance Division resulted in a fair value approximately 8% higher than its carrying value. The discounted cash flow approach for the Banking Division indicated a fair value approximately 20% higher than its carrying
value, and the market approach indicated a fair value approximately 9% higher than its carrying value. As a result, management determined no impairment existed at June 30, 2023.

Each of the valuation methods used by the Company requires significant assumptions. Depending on the specific method, assumptions are made regarding growth rates, discount rates for cash flows, control premiums, and selected multiples. Changes to any of the assumptions could result in significantly different results.

Nature of Business
Nature of Business

Ameris Bancorp (the “Company” or “Ameris”) is a financial holding company headquartered in Atlanta, Georgia. Ameris conducts substantially all of its operations through its wholly owned banking subsidiary, Ameris Bank (the “Bank”). At June 30, 2023, the Bank operated 164 branches in select markets in Georgia, Alabama, Florida, North Carolina and South Carolina. Our business model capitalizes on the efficiencies of a large financial services company, while still providing the community with the personalized banking service expected by our customers. We manage our Bank through a balance of decentralized management responsibilities and efficient centralized operating systems, products and loan underwriting standards. The Company’s Board of Directors and senior managers establish corporate policy, strategy and administrative policies. Within our established guidelines and policies, the banker closest to the customer responds to the differing needs and demands of his or her unique market.
Basis of Presentation
Basis of Presentation

The accompanying unaudited consolidated financial statements for Ameris have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statement presentation. The interim consolidated financial statements included herein are unaudited but reflect all adjustments, consisting of normal recurring adjustments, which, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the interim periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents Cash and Cash EquivalentsFor purposes of reporting cash flows, cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from banks, interest-bearing deposits in banks, federal funds sold and restricted cash. There was no restricted cash held at both June 30, 2023 and December 31, 2022.
Reclassifications ReclassificationsCertain reclassifications of prior year amounts have been made to conform with the current year presentations. The reclassifications had no effect on net income or shareholders' equity as previously reported.
Accounting Standards Adopted in 2023
Accounting Standards Adopted in 2023

ASU No. 2022-02 – Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). ASU 2022-02 eliminates the troubled debt restructuring ("TDR") measurement and recognition guidance and requires that entities evaluate whether the modification represents a new loan or a continuation of an existing loan consistent with the accounting for other loan modifications. Additional disclosures relating to modifications to borrowers experiencing financial difficulty are required under ASU 2022-02. ASU 2022-02 also requires disclosure of current-period gross write-offs by year of origination. The Company adopted this ASU effective January 1, 2023 on a prospective basis, except for the amendments related to recognition and measurement of TDRs, which were adopted using the modified retrospective method. The adoption was not material and resulted in a reduction to the allowance for credit losses of $1.7 million and an increase to retained earnings of $1.3 million.
ASU No. 2022-06 - Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU No. 2022-06 extends the temporary relief in Topic 848 from December 31, 2022 to December 31, 2024. Topic 848 provides optional guidance to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The objective of this guidance is to provide temporary relief during the transition period away from LIBOR toward new interest rate benchmarks. This update was effective upon issuance. The Company adopted the guidance in Topic 848 effective January 1, 2023 and the adoption was not material the consolidated financial statements.
