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, 2020, the Bank operated 170 branches in select markets in Georgia, Alabama, Florida 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 period ended June 30, 2020 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 and the report of our registered independent public accounting firm included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, as amended.
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 and federal funds sold. The Bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank of Atlanta.
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 and Pending Adoption	Accounting Standards Adopted in 2020 ASU 2018-15 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs incurred in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15"). ASU 2018-15 requires that application development stage implementation costs incurred in a Cloud Computing Arrangement ("CCA") that are service contracts be capitalized and amortized over the term of the hosting arrangement, including renewal option terms if the customer entity is reasonably certain to exercise the option. Costs incurred in the preliminary project and post-implementation stages are expensed as incurred. Training costs and certain data conversion costs also cannot be capitalized for a CCA that is a service contract. Amortization expense of capitalized implementation costs will be presented in the same income statement caption as the CCA fees. Similarly, capitalized implementation costs will be presented in the same balance sheet caption as any prepaid CCA fees, and cash flows from capitalized implementation costs will be classified in the statement of cash flows in the same manner as payments made for the CCA fees. The requirements of ASU 2018-15 should be applied either retrospectively or prospectively to all implementation costs incurred after the adoption date. ASU 2018-15 is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. During the first quarter of 2020, the Company adopted the provision of ASU 2018-15, and the adoption did not have a material impact on the Company's consolidated financial statements. ASU 2018-13 – Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13). ASU 2018-13 changes fair value measurement disclosure requirements by removing certain requirements, modifying certain requirements and adding certain new requirements. Disclosure requirements removed include the following: transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for determining when transfers between any of the three levels have occurred; the valuation processes for Level 3 measurements; and the changes in unrealized gains or losses presented in earnings for Level 3 instruments held at end of the reporting period. Disclosure requirements that have been modified include the following: for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee's assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and clarification that the Level 3 measurement uncertainty disclosure should communicate information about the uncertainty at the balance sheet date. New disclosure requirements include the following: the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 instruments held at the end of the reporting period; and the range and weighted average of significant unobservable inputs used for Level 3 measurements or disclosure of other quantitative information in place of the weighted average to the extent that it would be a more reasonable and rational method to reflect the distribution of unobservable inputs. ASU 2018-13 is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. During the first quarter of 2020, the Company adopted the provision of ASU 2018-13, and the adoption did not have a material impact on the Company's consolidated financial statements. ASU 2017-04 – Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 eliminates Step 2 from the goodwill impairment test to simplify the subsequent measurement of goodwill. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, the income tax effects of tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. ASU 2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The standard must be adopted using a prospective basis and the nature and reason for the change in accounting principle should be disclosed upon transition. ASU 2017-04 is effective for annual or any interim goodwill impairment tests in reporting periods beginning after December 15, 2019. Early adoption is permitted on testing dates after January 1, 2017. During the first quarter of 2020, the Company adopted the provision of ASU 2017-04, and the adoption did not have a material impact on the Company's consolidated financial statements. ASU 2016-13 – Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace the current incurred loss approach with an expected loss model, referred to as the current expected credit loss (“CECL”) model. The new standard will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance-sheet credit exposures, which include, but are not limited to, loans, leases, held-to-maturity securities, loan commitments and financial guarantees. ASU 2016-13 simplifies the accounting for purchased credit-impaired debt securities and loans and expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Upon adoption, ASU 2016-13 provides for a modified retrospective transition by means of a cumulative effect adjustment to equity as of the beginning of the period in which the guidance is effective. The Company adopted ASU 2016-13 and all related subsequent amendments thereto effective January 1, 2020 using the modified retrospective approach. The Company recognized an increase in the allowance for credit losses on loans of $78.7 million, an increase in the allowance for unfunded commitments of $12.7 million and a reduction of retained earnings of $56.7 million, net of the increase in deferred tax assets of $19.0 million. The Company adopted ASU 2016-13 using the prospective transition approach for purchased financial assets with credit deterioration ("PCD") that were previously classified as purchased credit impaired ("PCI") and accounted for under ASU 310-30. In accordance with ASU 2016-13, the Company did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The Company determined $15.6 million of existing discounts on PCD loans was related to credit factors and was reclassified to the ACL upon adoption. The remaining discount on the PCD assets was determined to be related to noncredit factors and will be accreted into interest income on a level-yield method over the life of the loans. In addition, for available-for-sale debt securities, the new methodology replaces the other-than-temporary impairment model and requires the recognition of an allowance for reductions in a security’s fair value attributable to declines in credit quality, instead of a direct write-down of the security, when a valuation decline is determined to be other-than-temporary. There was no financial impact related to this implementation. The Company has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest in other assets in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the three and six months ended June 30, 2020 and 2019. Accrued interest receivable on available-for-sale debt securities totaled $4.5 million as of June 30, 2020. Refer to Note 3 for additional information. Allowance for Credit Losses – Loans Under the current expected credit loss model, the allowance for credit losses (“ACL”) on loans is a valuation allowance estimated at each balance sheet date in accordance with GAAP that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, and net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the measurement of ACL. Accrued interest receivable on loans is reported in other assets on the consolidated balance sheets and totaled $67.7 million at June 30, 2020. Expected credit losses are reflected in the allowance for credit losses through a charge to provision for credit losses. When the Company deems all or a portion of a financial asset to be uncollectible the appropriate amount is written off and the ACL is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible; however, generally speaking, an asset will be considered uncollectible no later than when all efforts at collection have been exhausted. Subsequent recoveries, if any, are credited to the ACL when received. The Company measures expected credit losses of financial assets on a collective (pool) basis, when the financial assets share similar risk characteristics. Depending on the nature of the pool of financial assets with similar risk characteristics, the Company uses the discounted cash flow (“DCF”) method, the vintage method, the PD×LGD method or a qualitative approach as discussed further below. The Company’s methodologies for estimating the ACL 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 financial assets with similar risk characteristics for which the historical loss experience was observed. The Company’s methodologies revert back to historical loss information on a straight-line basis over four quarters when it can no longer develop reasonable and supportable forecasts. The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: Commercial, financial, and agricultural - These loans include both secured and unsecured loans for working capital, expansion, crop production and other business purposes. Commercial, financial and agricultural loans also include certain U.S. Small Business Administration (“SBA”) loans. Short-term working capital loans are secured by non-real estate collateral such as accounts receivable, crops, inventory and equipment. The Bank evaluates the financial strength, cash flow, management, credit history of the borrower and the quality of the collateral securing the loan. The Bank often requires personal guarantees and secondary sources of repayment on commercial, financial and agricultural loans. Consumer installment - These loans include home improvement loans, direct automobile loans, boat and recreational vehicle financing, and both secured and unsecured personal loans. Consumer loans carry greater risks than other loans, as the collateral can consist of rapidly depreciating assets such as automobiles and equipment that may not provide an adequate source of repayment of the loan in the case of default. Indirect automobile - Indirect automobile loans are secured by automobile collateral, generally new and used cars and trucks from auto dealers that operate within selected states. Repayment of these loans depends largely on the personal income of the borrowers which can be affected by changes in economic conditions such as unemployment levels. Collateral consists of rapidly depreciating assets that may not provide an adequate source of repayment of the loan in the event of default. Mortgage warehouse - Mortgage Warehouse facilities are provided to unaffiliated mortgage origination companies and are collateralized by one-to-four family residential loans or mortgage servicing rights. The originator closes new mortgage loans with the intent to sell these loans to third party investors for a profit. The Bank provides funding to the mortgage companies for the period between the origination and their sale of the loan. The Bank has a policy that requires that it separately validate that each residential mortgage loan was underwritten consistent with the underwriting requirements of the final investor or market standards prior to advancing funds. The Bank is repaid with the proceeds received from sale of the mortgage loan to the final investor. Municipal - Municipal loans consists of loans made to counties, municipalities and political subdivisions. The source of repayment for these loans is either general revenue of the municipality or revenues of the project being financed by the loan. These loans may be secured by real estate, machinery, equipment or assignment of certain revenues. Premium Finance - Premium finance provides loans for the acquisition of certain commercial insurance policies. Repayment of these loans is dependent on the cash flow of the insured which can be affected by changes in economic conditions. The Bank has procedures in place to cancel the insurance policy after default by the borrower to minimize the risk of loss. Real Estate - Construction and Development - Construction and development loans include loans for the development of residential neighborhoods, one-to-four family home residential construction loans to builders and consumers, and commercial real estate construction loans, primarily for owner-occupied and investment properties. The Company limits its construction lending risk through adherence to established underwriting procedures. Real Estate - Commercial and Farmland - Commercial real estate loans include loans secured by owner-occupied commercial buildings for office, storage, retail, farmland and warehouse space. They also include non-owner occupied commercial buildings such as leased retail and office space. Commercial real estate loans may be larger in size and may involve a greater degree of risk than one-to-four family residential mortgage loans. Payments on such loans are often dependent on successful operation or management of the properties. Real Estate - Residential - The Company's residential loans represent permanent mortgage financing and are secured by residential properties located within the Bank's market areas. Residential real estate loans also include purchased loan pools secured by residential properties located outside the Bank's market area. Discounted Cash Flow Method The Company uses the discounted cash flow method to estimate expected credit losses for the commercial, financial and agricultural, consumer installment, real estate - construction and development, real estate - commercial and farmland and real estate - residential loan segments. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical internal data adjusted based upon peer data. The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loan pools utilizing the DCF method, the Company uses a combination of national and regional data including gross domestic product, home price indices, unemployment rates, retail sales, and rental vacancy rates depending on the nature of the underlying loan pool and how well that loss driver correlates to expected future losses. For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over four quarters on a straight-line basis. Management leverages economic projections from a reputable and independent third party to inform its loss driver forecasts over the four-quarter forecast period. Other internal and external indicators of economic forecasts are also considered by management when developing the forecast metrics. The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows (“NPV”). An ACL is established for the difference between the instrument’s NPV and amortized cost basis. Vintage Method The Company uses a vintage method to estimate expected credit losses for the indirect automobile loans segment. The Company’s vintage analysis is based on loss rates by origination date and includes data on loan amounts, loan charge-offs and recoveries by date. Using this information, vintage tables are created to evaluate loss rate patterns and develop estimated losses by vintage year. Once the tables have been calculated, reserves are estimated by multiplying the balance of a given origination year by the remaining loss to be experienced by that vintage. PD×LGD Method The Company uses the PD×LGD method to estimate expected credit losses (“EL”) for the premium finance and municipal loan segments. Under the PD×LGD method, the loss rate is a function of two components: (1) the lifetime default rate (“PD”); and (2) the loss given default (“LGD”). For the premium finance loan segment, calculations of lifetime default rates and corresponding loss given default rates of static pools are performed. The PD×LGD method uses the default rates and loss given default rates of different static pools to quantify the relationship between those rates and the credit mix of the pools and applies that relationship on a going forward basis. The Company has not incurred any historical defaults or charge offs in its municipal portfolio. Therefore, in lieu of historical loss rates, the Company applies historical benchmarking PD and LGD ratios provided by a reputable and independent third party to the current municipal loan balance. Qualitative Factors The Company uses qualitative factors for model risk uncertainty as well as for loan segment specific risks that cannot be addressed in the quantitative methods. In particular, the warehouse loan segment uses a qualitative factor for fraud losses based upon historical fraud loss data since the Company has not experienced any credit related losses in this loan segment to date. Individually Evaluated Assets Loans that do not share risk characteristics are evaluated on an individual basis. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are 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. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized costs basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: (1) the borrower is experiencing financial difficulty; and (2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. The Company’s ACL reflects all effects of a TDR when an individual asset is specifically identified as a reasonably expected TDR. The Company has determined that a TDR is reasonably expected no later than the point when the lender concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession from the lender to avoid a default. Reasonably expected TDRs and executed non-performing TDRs are evaluated individually to determine the required ACL. TDRs performing in accordance with their modified contractual terms for a reasonable period of time may be included in the Company’s existing pools based on the underlying risk characteristics of the loan to measure the ACL. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancelable, through a charge to provision for unfunded commitments in the Company’s consolidated statements of income. The ACL on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur as well as any third-party guarantees and is included in other liabilities on the Company’s consolidated balance sheets. Guidance on Non-TDR Loan Modifications due to COVID-19 In April 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System (the "FRB") and the Federal Deposit Insurance Corporation (the "FDIC"), issued a revised interagency statement encouraging financial institutions to work with customers affected by the novel coronavirus pandemic (“COVID-19”) and providing additional information regarding loan modifications. The revised interagency statement clarifies the interaction between the interagency statement issued on March 22, 2020 and the temporary relief provided by Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). Section 4013 of the CARES Act allows financial institutions to suspend the requirements to classify certain loan modifications as TDRs. The revised statement also provides supervisory interpretations on past due and nonaccrual regulatory reporting of loan modification programs and regulatory capital. This interagency guidance is expected to reduce the number of TDRs that will be reported in future periods; however, the amount is indeterminable and will depend on future developments, which are highly uncertain and cannot be accurately predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic. Accounting Standards Pending Adoption ASU No. 2020-04 – Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The amendments, which are elective, provide expedients and exceptions for applying GAAP to contract modifications and hedging relationships affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate that is expected to be discontinued due to reference rate reform. The optional expedients for contract modifications apply consistently for all contracts or transactions within the relevant Codification Topic, Subtopic, or Industry Subtopic that contains the guidance that otherwise would be required to be applied, while those for hedging relationships can be elected on an individual hedging relationship basis. Because the guidance is intended to assist stakeholders during the global market-wide reference rate transition period, it is in effect for a limited time, from March 12, 2020 through December 31, 2022. The Company has established a working committee with representatives from relevant functional areas to inventory the contracts and accounts that are tied to LIBOR and develop a transition plan for the affected items. The Company is currently evaluating the impact of adopting ASU 2020-04 on the consolidated financial statements. ASU 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 simplifies the accounting for income taxes by removing certain technical exceptions. ASU 2019-12 also clarifies and amends the accounting for income taxes in certain areas including, among others: (i) franchise taxes that are partially based on income; (ii) whether step ups in the tax basis of goodwill should be considered part of the acquisition to which it related or recognized as a separate transaction; and (iii) requiring the effect of an enacted change in tax laws or rates to be reflected in the annual effective tax rate computation in the interim period that includes the enactment date. The Company expects to apply the amendments in this update on a modified retrospective basis for the provision related to franchise taxes and prospectively for all other amendments. ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact this ASU will have on the Company’s consolidated balance sheet, consolidated statement of income and comprehensive income, consolidated statement of shareholders’ equity and consolidated statement of cash flows, but it is not expected to have a material impact.

Upon adoption, ASU 2016-13 provides for a modified retrospective transition by means of a cumulative effect adjustment to equity as of the beginning of the period in which the guidance is effective.

The Company adopted ASU 2016-13 and all related subsequent amendments thereto effective January 1, 2020 using the modified retrospective approach. The Company recognized an increase in the allowance for credit losses on loans of $78.7 million, an increase in the allowance for unfunded commitments of $12.7 million and a reduction of retained earnings of $56.7 million, net of the increase in deferred tax assets of $19.0 million.

The Company adopted ASU 2016-13 using the prospective transition approach for purchased financial assets with credit deterioration ("PCD") that were previously classified as purchased credit impaired ("PCI") and accounted for under ASU 310-30. In accordance with ASU 2016-13, the Company did not reassess whether PCI assets met the criteria of PCD assets as

of the date of adoption. The Company determined $15.6 million of existing discounts on PCD loans was related to credit factors and was reclassified to the ACL upon adoption. The remaining discount on the PCD assets was determined to be related to noncredit factors and will be accreted into interest income on a level-yield method over the life of the loans.

In addition, for available-for-sale debt securities, the new methodology replaces the other-than-temporary impairment model and requires the recognition of an allowance for reductions in a security’s fair value attributable to declines in credit quality, instead of a direct write-down of the security, when a valuation decline is determined to be other-than-temporary. There was no financial impact related to this implementation. The Company has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest in other assets in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the three and six months ended June 30, 2020 and 2019. Accrued interest receivable on available-for-sale debt securities totaled $4.5 million as of June 30, 2020. Refer to Note 3 for additional information.

Allowance for Credit Losses – Loans

Under the current expected credit loss model, the allowance for credit losses (“ACL”) on loans is a valuation allowance estimated at each balance sheet date in accordance with GAAP that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans.

The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, and net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the measurement of ACL. Accrued interest receivable on loans is reported in other assets on the consolidated balance sheets and totaled $67.7 million at June 30, 2020.

Expected credit losses are reflected in the allowance for credit losses through a charge to provision for credit losses. When the Company deems all or a portion of a financial asset to be uncollectible the appropriate amount is written off and the ACL is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible; however, generally speaking, an asset will be considered uncollectible no later than when all efforts at collection have been exhausted. Subsequent recoveries, if any, are credited to the ACL when received.

The Company measures expected credit losses of financial assets on a collective (pool) basis, when the financial assets share similar risk characteristics. Depending on the nature of the pool of financial assets with similar risk characteristics, the Company uses the discounted cash flow (“DCF”) method, the vintage method, the PD×LGD method or a qualitative approach as discussed further below.

The Company’s methodologies for estimating the ACL 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 financial assets with similar risk characteristics for which the historical loss experience was observed. The Company’s methodologies revert back to historical loss information on a straight-line basis over four quarters when it can no longer develop reasonable and supportable forecasts.

The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses:

Commercial, financial, and agricultural - These loans include both secured and unsecured loans for working capital, expansion, crop production and other business purposes. Commercial, financial and agricultural loans also include certain U.S. Small Business Administration (“SBA”) loans. Short-term working capital loans are secured by non-real estate collateral such as accounts receivable, crops, inventory and equipment. The Bank evaluates the financial strength, cash flow, management, credit history of the borrower and the quality of the collateral securing the loan. The Bank often requires personal guarantees and secondary sources of repayment on commercial, financial and agricultural loans.

Consumer installment - These loans include home improvement loans, direct automobile loans, boat and recreational vehicle financing, and both secured and unsecured personal loans. Consumer loans carry greater risks than other loans, as the collateral

can consist of rapidly depreciating assets such as automobiles and equipment that may not provide an adequate source of repayment of the loan in the case of default.

Indirect automobile - Indirect automobile loans are secured by automobile collateral, generally new and used cars and trucks from auto dealers that operate within selected states. Repayment of these loans depends largely on the personal income of the borrowers which can be affected by changes in economic conditions such as unemployment levels. Collateral consists of rapidly depreciating assets that may not provide an adequate source of repayment of the loan in the event of default.

Mortgage warehouse - Mortgage Warehouse facilities are provided to unaffiliated mortgage origination companies and are collateralized by one-to-four family residential loans or mortgage servicing rights. The originator closes new mortgage loans with the intent to sell these loans to third party investors for a profit. The Bank provides funding to the mortgage companies for the period between the origination and their sale of the loan. The Bank has a policy that requires that it separately validate that each residential mortgage loan was underwritten consistent with the underwriting requirements of the final investor or market standards prior to advancing funds. The Bank is repaid with the proceeds received from sale of the mortgage loan to the final investor.

Municipal - Municipal loans consists of loans made to counties, municipalities and political subdivisions. The source of repayment for these loans is either general revenue of the municipality or revenues of the project being financed by the loan. These loans may be secured by real estate, machinery, equipment or assignment of certain revenues.

Premium Finance - Premium finance provides loans for the acquisition of certain commercial insurance policies. Repayment of these loans is dependent on the cash flow of the insured which can be affected by changes in economic conditions. The Bank has procedures in place to cancel the insurance policy after default by the borrower to minimize the risk of loss.

Real Estate - Construction and Development - Construction and development loans include loans for the development of residential neighborhoods, one-to-four family home residential construction loans to builders and consumers, and commercial real estate construction loans, primarily for owner-occupied and investment properties. The Company limits its construction lending risk through adherence to established underwriting procedures.

Real Estate - Commercial and Farmland - Commercial real estate loans include loans secured by owner-occupied commercial buildings for office, storage, retail, farmland and warehouse space. They also include non-owner occupied commercial buildings such as leased retail and office space. Commercial real estate loans may be larger in size and may involve a greater degree of risk than one-to-four family residential mortgage loans. Payments on such loans are often dependent on successful operation or management of the properties.

Real Estate - Residential - The Company's residential loans represent permanent mortgage financing and are secured by residential properties located within the Bank's market areas. Residential real estate loans also include purchased loan pools secured by residential properties located outside the Bank's market area.

Discounted Cash Flow Method

The Company uses the discounted cash flow method to estimate expected credit losses for the commercial, financial and agricultural, consumer installment, real estate - construction and development, real estate - commercial and farmland and real estate - residential loan segments. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical internal data adjusted based upon peer data.

The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loan pools utilizing the DCF method, the Company uses a combination of national and regional data including gross domestic product, home price indices, unemployment rates, retail sales, and rental vacancy rates depending on the nature of the underlying loan pool and how well that loss driver correlates to expected future losses.

For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over four quarters on a straight-line basis. Management leverages economic projections from a reputable and independent third party to inform its loss driver forecasts over the four-quarter forecast period. Other internal and external indicators of economic forecasts are also considered by management when developing the forecast metrics.

The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows (“NPV”). An ACL is established for the difference between the instrument’s NPV and amortized cost basis.

Vintage Method

The Company uses a vintage method to estimate expected credit losses for the indirect automobile loans segment. The Company’s vintage analysis is based on loss rates by origination date and includes data on loan amounts, loan charge-offs and recoveries by date. Using this information, vintage tables are created to evaluate loss rate patterns and develop estimated losses by vintage year. Once the tables have been calculated, reserves are estimated by multiplying the balance of a given origination year by the remaining loss to be experienced by that vintage.

PD×LGD Method

The Company uses the PD×LGD method to estimate expected credit losses (“EL”) for the premium finance and municipal loan segments. Under the PD×LGD method, the loss rate is a function of two components: (1) the lifetime default rate (“PD”); and (2) the loss given default (“LGD”). For the premium finance loan segment, calculations of lifetime default rates and corresponding loss given default rates of static pools are performed. The PD×LGD method uses the default rates and loss given default rates of different static pools to quantify the relationship between those rates and the credit mix of the pools and applies that relationship on a going forward basis. The Company has not incurred any historical defaults or charge offs in its municipal portfolio. Therefore, in lieu of historical loss rates, the Company applies historical benchmarking PD and LGD ratios provided by a reputable and independent third party to the current municipal loan balance.

Qualitative Factors

The Company uses qualitative factors for model risk uncertainty as well as for loan segment specific risks that cannot be addressed in the quantitative methods. In particular, the warehouse loan segment uses a qualitative factor for fraud losses based upon historical fraud loss data since the Company has not experienced any credit related losses in this loan segment to date.

Individually Evaluated Assets

Loans that do not share risk characteristics are evaluated on an individual basis. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are 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. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized costs basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset.

The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring.

A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: (1) the borrower is experiencing financial difficulty; and (2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. The Company’s ACL reflects all effects of a TDR when an individual asset is specifically identified as a reasonably expected TDR. The Company has determined that a TDR is reasonably expected no later than the point when the lender concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession from the lender to avoid a default. Reasonably expected TDRs and executed non-performing TDRs are evaluated individually to determine the required ACL. TDRs performing in accordance with their modified contractual terms for a reasonable period of time may be included in the Company’s existing pools based on the underlying risk characteristics of the loan to measure the ACL.

Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded.

The Company records an allowance for credit losses on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancelable, through a charge to provision for unfunded commitments in the Company’s consolidated statements of income. The ACL on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur as well as any third-party guarantees and is included in other liabilities on the Company’s consolidated balance sheets.

Guidance on Non-TDR Loan Modifications due to COVID-19

In April 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System (the "FRB") and the Federal Deposit Insurance Corporation (the "FDIC"), issued a revised interagency statement encouraging financial institutions to work with customers affected by the novel coronavirus pandemic (“COVID-19”) and providing additional information regarding loan modifications. The revised interagency statement clarifies the interaction between the interagency statement issued on March 22, 2020 and the temporary relief provided by Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). Section 4013 of the CARES Act allows financial institutions to suspend the requirements to classify certain loan modifications as TDRs. The revised statement also provides supervisory interpretations on past due and nonaccrual regulatory reporting of loan modification programs and regulatory capital. This interagency guidance is expected to reduce the number of TDRs that will be reported in future periods; however, the amount is indeterminable and will depend on future developments, which are highly uncertain and cannot be accurately predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

Accounting Standards Pending Adoption

ASU No. 2020-04 – Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The amendments, which are elective, provide expedients and exceptions for applying GAAP to contract modifications and hedging relationships affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate that is expected to be discontinued due to reference rate reform. The optional expedients for contract modifications apply consistently for all contracts or transactions within the relevant Codification Topic, Subtopic, or Industry Subtopic that contains the guidance that otherwise would be required to be applied, while those for hedging relationships can be elected on an individual hedging relationship basis. Because the guidance is intended to assist stakeholders during the global market-wide reference rate transition period, it is in effect for a limited time, from March 12, 2020 through December 31, 2022. The Company has established a working committee with representatives from relevant functional areas to inventory the contracts and accounts that are tied to LIBOR and develop a transition plan for the affected items. The Company is currently evaluating the impact of adopting ASU 2020-04 on the consolidated financial statements.

ASU 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 simplifies the accounting for income taxes by removing certain technical exceptions. ASU 2019-12 also clarifies and amends the accounting for income taxes in certain areas including, among others: (i) franchise taxes that are partially based on income; (ii) whether step ups in the tax basis of goodwill should be considered part of the acquisition to which it related or recognized as a separate transaction; and (iii) requiring the effect of an enacted change in tax laws or rates to be reflected in the annual effective tax rate computation in the interim period that includes the enactment date. The Company expects to apply the amendments in this update on a modified retrospective basis for the provision related to franchise taxes and prospectively for all other amendments. ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact this ASU will have on the Company’s consolidated balance sheet, consolidated statement of income and comprehensive income, consolidated statement of shareholders’ equity and consolidated statement of cash flows, but it is not expected to have a material impact.
