Accounting Policies [Abstract]
Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation Simmons First National Corporation (“Company”) is a Mid-South financial holding company headquartered in Pine Bluff, Arkansas, and the parent company of Simmons Bank, an Arkansas state-chartered bank that has been in operation since 1903 (“Simmons Bank” or the “Bank”). Simmons First Insurance Services, Inc. and Simmons First Insurance Services of TN, LLC are wholly-owned subsidiaries of Simmons Bank and are insurance agencies that offer various lines of personal and corporate insurance coverage to individual and commercial customers. The Company, through its subsidiaries, offers, among other things, consumer, real estate and commercial loans; checking, savings and time deposits; and specialized products and services (such as credit cards, trust and fiduciary services, investments, agricultural finance lending, equipment lending, insurance and Small Business Administration (“SBA”) lending) from approximately 199 financial centers as of December 31, 2021, located throughout market areas in Arkansas, Kansas, Missouri, Oklahoma, Tennessee and Texas. The consolidated financial statements include the accounts of the Company and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation. Simmons Bank is an Arkansas state-chartered bank and a member of the Federal Reserve System through the Federal Reserve Bank of St. Louis. Due to the Company’s typical acquisition process, there may be brief periods of time during which the Company may operate another subsidiary bank that the Company acquired through a merger with a target bank holding company as a separate subsidiary while preparing for the merger and integration of that subsidiary bank into Simmons Bank. However, it is the Company’s intent to generally maintain Simmons Bank as the Company’s sole subsidiary bank.
Operating Segments	Operating Segments Operating segments are components of an enterprise about which separate financial information is available that is regularly evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company is organized on a divisional basis, with divisions grouped based on community and metro markets located within the Company’s footprint. Each of the divisions, as well as their respective groups, provide a group of similar community banking services, including such products and services as loans; time deposits, checking and savings accounts; treasury management, personal and corporate trust services; credit cards; investment management; insurance; and securities and investment services. Loan products include consumer, real estate, commercial, agricultural, equipment, warehouse lending and SBA lending. The individual bank divisions have similar operating and economic characteristics. While the chief operating decision maker monitors the revenue streams of the various products, services, branch locations, divisions and groups, operations are managed, financial performance is evaluated, and management makes decisions on how to allocate resources, on a Company-wide basis. Accordingly, the divisions and their respective groups are considered by management to be aggregated into one reportable operating segment. The Company also considers its trust, investment and insurance services to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under Accounting Standards Codification (“ASC”) Topic 280-10-50-12.
Use of Estimates	Use of Estimates The preparation of financial statements, in accordance with US GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income items and expenses and disclosure of contingent assets and liabilities. The estimates and assumptions used in the accompanying consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the consolidated financial statements and actual results may differ from these estimates. Such estimates include, but are not limited to, the Company’s allowance for credit losses. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of acquired loans. Management obtains independent appraisals for significant properties in connection with the determination of the allowance for credit losses and the valuation of foreclosed assets.
Reclassifications	Reclassifications During 2021, certain debit and credit card transaction fees were reclassified from non-interest expense to non-interest income. These transaction fees, as well as additional certain prior year amounts, have been reclassified to conform to the current year financial statement presentation. These changes and reclassifications did not impact previously reported net income or comprehensive income and were not material to the consolidated financial statements. During 2020, the Company moved equity securities from the available-for-sale investment securities into other assets as well as the related income which moved from interest income to non-interest income. The change had no impact on net income. Various items within the accompanying consolidated financial statements for previous years have been reclassified to provide more comparative information. These reclassifications were not material to the consolidated financial statements.
Cash Equivalents	Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. For purposes of the consolidated statements of cash flows, cash and cash equivalents are considered to include cash and non-interest bearing balances due from banks, interest bearing balances due from banks and federal funds sold and securities purchased under agreements to resell. At December 31, 2021, nearly all of the interest-bearing and non-interest bearing deposits were uninsured with nearly all of these balances held at the Federal Reserve Bank.
Investment Securities and Allowance for Credit Losses - Investment Securities	Investment Securities Held-to-maturity securities (“HTM”), which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant effective yield method over the estimated life of the security. Prepayments are anticipated for mortgage-backed and SBA securities. Premiums on callable securities are amortized to their earliest call date. Available-for-sale securities (“AFS”), which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Realized gains and losses, based on specifically identified amortized cost of the individual security, are included in other income. Unrealized gains and losses are recorded, net of related income tax effects, in stockholders’ equity. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant effective yield method over the estimated life of the security. Prepayments are anticipated for mortgage-backed and SBA securities. Premiums on callable securities are amortized to their earliest call date. Trading securities, if any, which include any security held primarily for near-term sale, are carried at fair value. Gains and losses on trading securities are included in other income. Allowance for Credit Losses - Investment Securities Allowance for Credit Losses - HTM Securities - The Company measures expected credit losses on HTM securities on a collective basis by major security type, with each type sharing similar risk characteristics. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Company has made the election to exclude accrued interest receivable on HTM securities from the estimate of credit losses and report accrued interest separately on the consolidated balance sheets. Allowance for Credit Losses - AFS Securities - For AFS securities in an unrealized loss position, the Company first evaluates whether it intends to sell, or whether it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either of these criteria regarding intent or requirement to sell is met, the AFS security amortized cost basis is written down to fair value through income. If the criteria is not met, the Company is required to assess whether the decline in fair value has resulted from credit losses or noncredit-related factors. If the assessment indicates a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists, and an allowance for credit loss is recorded through income as a component of provision for credit loss expense. If the assessment indicates that a credit loss does not exist, the Company records the decline in fair value through other comprehensive income, net of related income tax effects. The Company has made the election to exclude accrued interest receivable on AFS securities from the estimate of credit losses and report accrued interest separately on the consolidated balance sheets. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met.
Mortgage Loans Held For Sale	Mortgage Loans Held For Sale Mortgage Loans Held for Sale are carried at fair value which is determined on an aggregate basis. Adjustments to fair value are recognized monthly and reflected in earnings. The Company regularly sells mortgages into the capital markets to mitigate the effects of interest rate volatility during the period from the time an interest rate lock commitment (“IRLC”) is issued until the IRLC funds creating a mortgage loan held for sale and its subsequent sale into the secondary/capital markets. Loan sales are typically executed on a mandatory basis. Under a mandatory commitment, the Company agrees to deliver a specified dollar amount with predetermined terms by a certain date. Generally, the commitment is not loan specific, and any combination of loans can be delivered into the outstanding commitment provided the terms fall within the parameters of the commitment. Upon failure to deliver, the Company is subject to fees based on market movement. The IRLCs are derivative instruments; their fair values at December 31, 2021 and 2020 were not material. Gains and losses resulting from sales of mortgage loans are recognized when the respective loans are sold to correspondent lenders, investors or aggregators. Gains and losses are determined by the difference between the sale price and the carrying amount in the loans sold, net of discounts collected, or premiums paid. Hedge instruments are, likewise, carried at fair value and associated gains/losses are realized at time of settlement.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-offs are reported at their amortized cost basis, which is the unpaid principal balance outstanding, net of unearned income, deferred loan fees and costs, premiums and discounts associated with acquisition date fair value adjustments on acquired loans, and any direct principal charge-offs. The Company has made a policy election to exclude accrued interest from the amortized cost basis of loans and report accrued interest separately from the related loan balance on the consolidated balance sheets. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on loans, except on certain government guaranteed loans, is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on non-accrual or charged off at an earlier date if collection of principal or interest is considered doubtful. Discounts and premiums on purchased residential real estate loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method. Further information regarding accounting policies related to past due loans, non-accrual loans, and troubled-debt restructurings is presented in Note 5, Loans and Allowance for Credit Losses. Additionally, for discussion of the Company’s accounting for acquired loans, see Acquisition Accounting, Loans later in this section.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses is a reserve established through a provision for credit losses charged to expense, which represents management’s best estimate of lifetime expected losses based on reasonable and supportable forecasts, historical loss experience, and other qualitative considerations. The allowance, in the judgment of management, is necessary to reserve for expected credit losses and risks inherent in the loan portfolio. The Company’s allowance for credit loss methodology includes reserve factors calculated to estimate current expected credit losses to amortized cost balances over the remaining contractual life of the portfolio, adjusted for prepayments, in accordance with ASC Topic 326-20, Financial Instruments - Credit Losses. Accordingly, the methodology is based on the Company’s reasonable and supportable economic forecasts, historical loss experience, and other qualitative adjustments. Management’s evaluation of the allowance for credit losses is inherently subjective as it requires material estimates. It is management’s practice to review the allowance on a monthly basis, and after considering the factors previously noted, to determine the level of provision made to the allowance. Loans with similar risk characteristics such as loan type, collateral type, and internal risk ratings are aggregated into homogeneous segments for assessment. Reserve factors are based on estimated probability of default and loss given default for each segment. The estimates are determined based on economic forecasts over the reasonable and supportable forecast period based on projected performance of economic variables that have a statistical relationship with the historical loss experience of the segments. For contractual periods that extend beyond the one-year forecast period, the estimates revert to average historical loss experiences over a one-year period on a straight-line basis. The Company also includes qualitative adjustments to the allowance based on factors and considerations that have not otherwise been fully accounted for. Qualitative adjustments include, but are not limited to: •Changes in asset quality - Adjustments related to trending credit quality metrics including delinquency, nonperforming loans, charge-offs, and risk ratings that may not be fully accounted for in the reserve factor. •Changes in the nature and volume of the portfolio - Adjustments related to current changes in the loan portfolio that are not fully represented or accounted for in the reserve factors. •Changes in lending and loan monitoring policies and procedures - Adjustments related to current changes in lending and loan monitoring procedures as well as review of specific internal policy compliance metrics. •Changes in the experience, ability, and depth of lending management and other relevant staff - Adjustments to measure increasing or decreasing credit risk related to lending and loan monitoring management. •Changes in the value of underlying collateral of collateralized loans - Adjustments related to improving or deterioration of the value of underlying collateral that are not fully captured in the reserve factors. •Changes in and the existence and effect of any concentrations of credit - Adjustments related to credit risk of specific industries that are not fully captured in the reserve factors. •Changes in regional and local economic and business conditions and developments - Adjustments related to expected and current economic conditions at a regional or local-level that are not fully captured within the Company’s reasonable and supportable forecast. •Data imprecisions due to limited historical loss data - Adjustments related to limited historical loss data that is representative of the collective loan portfolio. Collateral Dependent Loans 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 allowance for credit loss 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 allowance for credit losses may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. For a collateral dependent loan, the Company’s evaluation process includes a valuation by appraisal or other collateral analysis adjusted for selling costs, when appropriate. This valuation is compared to the remaining outstanding principal balance of the loan. If a loss is determined to be probable, the loss is included in the allowance for credit losses as a specific allocation. If the loan is not collateral dependent, the measurement of loss is based on the difference between the expected and contractual future cash flows of the loan.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments In addition to the allowance for credit losses, the Company has established a reserve for unfunded commitments, classified in other liabilities, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. This reserve is maintained at a level management believes to be sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined quarterly based on methodology similar to the methodology for determining the allowance for credit losses. The allowance for credit loss is reported as a component of accrued interest and other liabilities in the consolidated balance sheets. Adjustments to the allowance are reported in the income statement as a component of the provision for credit losses.
Acquisition Accounting, Loans	Acquisition Accounting, Loans The Company accounts for its acquisitions under ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. The fair value for acquired loans at the time of acquisition is based on a variety of factors including discounted expected cash flows, adjusted for estimated prepayments and credit losses. In accordance with ASC 326, the fair value adjustment is recorded as premium or discount to the unpaid principal balance of each acquired loan. Loans that have been identified as having experienced a more-than-insignificant deterioration in credit quality since origination is a purchased credit deteriorated (“PCD”) loan. The net premium or discount on PCD loans is adjusted by the Company’s allowance for credit losses recorded at the time of acquisition. The remaining net premium or discount is accreted or amortized into interest income over the remaining life of the loan using a constant yield method. The net premium or discount on loans that are not classified as PCD (“non-PCD”), that includes credit and non-credit components, is accreted or amortized into interest income over the remaining life of the loan using a constant yield method. The Company then records the necessary allowance for credit losses on the non-PCD loans through provision for credit losses expense. For further discussion of our acquisition and loan accounting, see Note 2, Acquisitions, and Note 5, Loans and Allowance for Credit Losses.
Trust Assets	Trust Assets Trust assets (other than cash deposits) held by the Company in fiduciary or agency capacities for its customers are not included in the accompanying consolidated balance sheets since such items are not assets of the Company.
Premises and Equipment	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized by the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Right-of-use lease assets are operating leases with a term greater than one year and are included in premises and equipment.
Foreclosed Assets Held For Sale	Foreclosed Assets Held For Sale Assets acquired by foreclosure or in settlement of debt and held for sale are valued at estimated fair value less estimated cost to sell as of the date of foreclosure. Management evaluates the value of foreclosed assets held for sale periodically and any decreases in the fair value are charged to other expense.
Bank Owned Life Insurance	Bank Owned Life Insurance The Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of non-interest income in the Company’s consolidated statements of income.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be separately distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The Company performs an annual goodwill impairment test, and more than annually if circumstances warrant, in accordance with ASC Topic 350, Intangibles – Goodwill and Other, as amended by Accounting Standards Update (“ASU”) 2011-08 - Testing Goodwill for Impairment. ASC Topic 350 requires that goodwill and intangible assets that have indefinite lives be reviewed for impairment annually, or more frequently if certain conditions occur. Intangible assets with finite lives are amortized over the estimated life of the asset, and are reviewed for impairment whenever events or changes in circumstances indicated that the carrying value may not be recoverable. Impairment losses on recorded goodwill, if any, will be recorded as operating expenses.
Derivative Financial Instruments	Derivative Financial Instruments The Company may enter into derivative contracts for the purposes of managing exposure to interest rate risk to meet the financing needs of its customers. A derivative instrument is a financial tool which derives its value from the value of some other financial instrument, variable index, including certain hedging instruments embedded in other contracts. These products are primarily designed to reduce interest rate risk for either the Company or its customers who proactively manage these risks. The Company records all derivatives on the balance sheet at fair value. In an effort to meet the financing needs of its customers and mitigate the impact of changing interest rates on the fair value of AFS securities, the Company has entered into fair value hedges. Fair value hedges include interest rate swap agreements on fixed rate loans and fixed rate callable AFS securities. To qualify for hedge accounting, derivatives must be highly effective at reducing the risk associated with the exposure being hedged and must be designated as a hedge at the point of inception of the derivative contract. For derivatives designated as hedging the exposure to changes in the fair value of the hedged item, the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain of the hedging instrument. The fair value hedges are considered to be highly effective and any hedge ineffectiveness was deemed not material. Fair value adjustments related to cash flow hedges are recorded in other comprehensive income and are reclassified to earnings when the hedged transaction is reflected in earnings.
Securities Sold Under Agreements to Repurchase	Securities Sold Under Agreements to Repurchase The Company sells securities under agreements to repurchase to meet customer needs for sweep accounts. At the point funds deposited by customers become investable, those funds are used to purchase securities owned by the Company and held in its general account with the designation of Customers’ Securities. A third party maintains control over the securities underlying overnight repurchase agreements. The securities involved in these transactions are generally U.S. Treasury or Federal Agency issues. Securities sold under agreements to repurchase generally mature on the banking day following that on which the investment was initially purchased and are treated as collateralized financing transactions which are recorded at the amounts at which the securities were sold plus accrued interest. Interest rates and maturity dates of the securities involved vary and are not intended to be matched with funds from customers.
Revenue from Contracts with Customers	Revenue from Contracts with Customers ASC Topic 606, Revenue from Contracts with Customers, applies to all contracts with customers to provide goods or services in the ordinary course of business. However, Topic 606 specifically does not apply to revenue related to financial instruments, guarantees, insurance contracts, leases, or nonmonetary exchanges. Given these scope exceptions, interest income recognition and measurement related to loans and investments securities, the Company’s two largest sources of revenue, are not accounted for under Topic 606. Also, the Company does not use Topic 606 to account for gains or losses on its investments in securities, loans, and derivatives due to the scope exceptions. Certain revenue streams, such as service charges on deposit accounts, gains or losses on the sale of OREO, and trust income, fall under the scope of Topic 606 and the Company must recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. Topic 606 is applied using five steps: 1) identify the contract with the customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company has evaluated the nature of all contracts with customers that fall under the scope of Topic 606 and determined that further disaggregation of revenue from contracts with customers into categories was not necessary. There has not been significant revenue recognized in the current reporting periods resulting from performance obligations satisfied in previous periods. In addition, there has not been a significant change in timing of revenues received from customers. A description of performance obligations for each type of contract with customers is as follows: Service charges on deposit accounts – The Company’s primary source of funding comes from deposit accounts with its customers. Customers pay certain fees to access their cash on deposit including, but not limited to, non-transactional fees such as account maintenance, dormancy or statement rendering fees, and certain transaction-based fees such as ATM, wire transfer, overdraft or returned check fees. The Company generally satisfies its performance obligations as services are rendered. The transaction prices are fixed, and are charged either on a periodic basis or based on activity. Sale of OREO – In the normal course of business, the Company will enter into contracts with customers to sell OREO, which has generally been foreclosed upon by the Company. The Company generally satisfies its performance obligation upon conveyance of property from the Company to the customer, generally by way of an executed agreement. The transaction price is fixed, and on occasion the Company will finance a portion of the proceeds the customers uses to purchase the property. These properties are generally sold without recourse or warranty. Wealth Management Fees – The Company enters into contracts with its customers to manage assets for investment, and/or transact on their accounts. The Company generally satisfies its performance obligations as services are rendered. The management fee is a fixed percentage-based fee calculated upon the average balance of assets under management and is charged to customers on a monthly basis.
Bankcard Fee Income	Bankcard Fee Income – Periodic bankcard fees, net of direct origination costs, are recognized as revenue on a straight-line basis over the period the fee entitles the cardholder to use the card.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance in ASC Topic 740, Income Taxes. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company files consolidated income tax returns with its subsidiaries.
Earnings Per Share	Earnings Per Share Basic earnings per share are computed based on the weighted average number of shares outstanding during each year. Diluted earnings per share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period.
Stock-Based Compensation	Stock-Based Compensation The Company has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and performance stock units. Pursuant to the plans, shares are reserved for future issuance by the Company, upon exercise of stock options or awarding of performance or bonus shares granted to directors, officers and other key employees. In accordance with ASC Topic 718, Compensation – Stock Compensation, the fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses various assumptions. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate.
New Accounting Standards	Recently Adopted Accounting Standards Reference Rate Reform – In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides relief for companies preparing for discontinuation of interest rates such as LIBOR. LIBOR is a benchmark interest rate referenced in a variety of agreements that are used by numerous entities. On March 5, 2021, the U.K. Financial Conduct Authority (“FCA”) announced that the majority of LIBOR rates will no longer be published after December 31, 2021, although a number of key settings will continue until June 2023, to support the rundown of legacy contracts only. As a result, LIBOR should be discontinued as a reference rate. Other interest rates used globally could also be discontinued for similar reasons. ASU 2020-04 provides optional expedients and exceptions to contracts, hedging relationships and other transactions affected by reference rate reform. The main provisions for contract modifications include optional relief by allowing the modification as a continuation of the existing contract without additional analysis and other optional expedients regarding embedded features. Optional expedients for hedge accounting permits changes to critical terms of hedging relationships and to the designated benchmark interest rate in a fair value hedge and also provides relief for assessing hedge effectiveness for cash flow hedges. Companies are able to apply ASU 2020-04 immediately; however, the guidance will only be available for a limited time (generally through December 31, 2022). The Company formed a LIBOR Transition Team in 2020, has created standard LIBOR replacement language for new and modified loan notes, and is monitoring the remaining loans with LIBOR rates monthly to ensure progress in updating these loans with acceptable LIBOR replacement language or converting them to other interest rates. The Company has not been offering LIBOR-indexed rates originated by other banks, subject to the Company’s determination that the LIBOR replacement language in the loan documents meets the Company’s standards. Pursuant to the Interagency Statement on LIBOR Transition issued in November 2020, the Company will not enter into any new LIBOR-based credit agreements after December 31, 2021. The adoption of ASU 2020-04 has not had a material impact on the Company’s financial position or results of operations. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”), which clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the changes in the interest rates used for margining, discounting, or contract price alignment for derivative instruments that are being implemented as part of the market-wide transition to new reference rates (commonly referred to as the “discounting transition”). ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance and generally can be applied through December 31, 2022. ASU 2021-01 did not have a material impact on the Company’s financial position or results of operations. Income Taxes – In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), that removes certain exceptions for investments, intraperiod allocations and interim calculations, and adds guidance to reduce complexity in accounting for income taxes. ASU 2019-12 introduces the following new guidance: i) guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination in which book goodwill was recognized or a separate transaction and ii) a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax. Additionally, ASU 2019-12 changes the following current guidance: i) making an intraperiod allocation, if there is a loss in continuing operations and gains outside of continuing operations, ii) determining when a deferred tax liability is recognized after an investor in a foreign entity transitions to or from the equity method of accounting, iii) accounting for tax law changes and year-to-date losses in interim periods, and iv) determining how to apply the income tax guidance to franchise taxes that are partially based on income. ASU 2019-12 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2020. The adoption of ASU 2019-12 did not have a material impact on the Company’s operations, financial position or disclosures. Fair Value Measurement Disclosures – In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), that eliminates, amends and adds disclosure requirements for fair value measurements. These amendments are part of FASB’s disclosure review project and are expected to reduce costs for preparers while providing more decision-useful information for financial statement users. The eliminated disclosure requirements include the 1) the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy; 2) the policy of timing of transfers between levels of the fair value hierarchy; and 3) the valuation processes for Level 3 fair value measurements. Among other modifications, the amended disclosure requirements remove the term “at a minimum” from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities and clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Under the new disclosure requirements, entities must disclose the changes in unrealized gains or losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The adoption of ASU 2018-13 did not have a material impact on the Company’s fair value disclosures. Credit Losses on Financial Instruments – In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires earlier measurement of credit losses, expands the range of information considered in determining expected credit losses and enhances disclosures. The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments replace the incurred loss impairment methodology in current US GAAP with a methodology (the current expected credit losses, or “CECL”, methodology) that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The CECL methodology utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to-maturity debt securities and other receivables measured at amortized cost at the time the financial asset is originated or acquired. The allowance for credit losses is adjusted each period for changes in expected lifetime credit losses. This methodology replaces the multiple existing impairment methods in current guidance, which generally require that a loss be incurred before it is recognized. Within the life cycle of a loan or other financial asset, this new guidance will generally result in the earlier recognition of the provision for credit losses and the related allowance for credit losses than current practice. For available-for-sale debt securities that the Company intends to hold and where fair value is less than cost, credit-related impairment, if any, will be recognized through an allowance for credit losses and adjusted each period for changes in credit risk. The effective date for these amendments is for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In preparation for implementation of ASU 2016-13, the Company formed a cross functional team that assessed its data and system needs and evaluated the potential impact of adopting the new guidance. The Company anticipated a significant change in the processes and procedures to calculate the loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the prior accounting practice that utilized the incurred loss model. On March 27, 2020, the CARES Act was signed in to law by the President of the United States and allowed the option to temporarily defer or suspend the adoption of ASU 2016-13. During the deferral, a registrant would continue to use the incurred loss model for the allowance for loan and lease losses and would be in accordance with US GAAP. The Company has not elected to temporarily defer the adoption of ASU 2016-13 and adopted the new standard as of January 1, 2020. Upon adoption, the Company recorded an additional allowance for credit losses on loans of approximately $151.4 million and an adjustment to the reserve for unfunded commitments recorded in other liabilities of $24.0 million. The Company also recorded an additional allowance for credit losses on investment securities of $742,000. The impact at adoption was reflected as an adjustment to beginning retained earnings, net of income taxes, in the amount of $128.1 million. The significant impact to the Company’s allowance for credit losses at the date of adoption was driven by the substantial amount of loans acquired held by the Company. The Company had approximately one third of total loans categorized as acquired at the adoption date with very little reserve allocated to them due to the previous incurred loss impairment methodology. As such, the amount of the CECL adoption impact was greater on the Company when compared to a non-acquisitive bank. In December 2018, the Federal Reserve, Office of the Comptroller of the Currency and FDIC (collectively, the “agencies”) issued a final rule revising regulatory capital rules in anticipation of the adoption of ASU 2016-13 that provided an option to phase in over a three year period on a straight line basis the day-one impact on earnings and Tier 1 capital (the “CECL Transition Provision”). In March 2020 and in response to the COVID-19 pandemic, the agencies issued a new regulatory capital rule revising the CECL Transition Provision to delay the estimated impact on regulatory capital stemming from the implementation of ASU 2016-13. The rule provides banking organizations that implement CECL before the end of 2020 the option to delay for two years an estimate of CECL’s effect on regulatory capital, followed by a three-year transition period (the “2020 CECL Transition Provision”). The Company elected to apply the 2020 CECL Transition Provision. Derivatives and Hedging: Targeted Improvements - In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), that changes both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in order to better align a company’s risk management activities and financial reporting for hedging relationships. In summary, this amendment 1) expands the types of transactions eligible for hedge accounting; 2) eliminates the separate measurement and presentation of hedge ineffectiveness; 3) simplifies the requirements around the assessment of hedge effectiveness; 4) provides companies more time to finalize hedge documentation; and 5) enhances presentation and disclosure requirements. The effective date was for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. All transition requirements and elections should be applied to existing hedging relationships on the date of adoption and the effects should be reflected as of the beginning of the fiscal year of adoption. As part of this new guidance, entities are allowed to designate as the hedged item, an amount that is not expected to be affected by prepayments, defaults or other events affecting the timing and amount of cash flows in a closed portfolio of prepayable financial instruments (this is referred to as the “last-of-layer” method). Under the last-of-layer method, entities are able to reclassify, only at the time of adoption, eligible callable debt securities from held-to-maturity to available-for-sale without tainting its intentions to hold future debt securities to maturity. The available-for-sale security must be reported at fair value and any unrealized gain or loss must be recorded as an adjustment to other comprehensive income upon adoption. The Company evaluated its held-to-maturity portfolio during the first quarter 2019 and identified certain municipal bonds with a fair value of $216.4 million that met the last-of-layer criteria under ASU 2017-12 and as a result, reclassified those to available-for-sale and recorded an unrealized gain of $2.5 million in accumulated other comprehensive income during the first quarter of 2019. Leases - In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), that establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. The new guidance results in a more consistent representation of the rights and obligations arising from leases by requiring lessees to recognize the lease asset and lease liabilities that arise from leases in the consolidated balance sheet and to disclose qualitative and quantitative information about lease transactions, such as information about variable lease payments and options to renew and terminate leases. The effective date was for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. ASU 2016-02 requires entities to adopt the new lease standard using a modified retrospective transition method, meaning an entity initially applies the new lease standard at the beginning of the earliest period presented in the financial statements. Due to complexities associated with using this method, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to relieve entities of the requirement to present prior comparative years’ results when they adopt the new lease standard and giving entities the option to recognize the cumulative effect of applying the new standard as an adjustment to the opening balance of retained earnings. Adoption of ASU 2016-02 resulted in the recognition of right-of-use assets of $32.8 million and right-of-use liabilities of $32.8 million on the consolidated balance sheet with no material impact to the results of operations. The Company has elected to adopt the guidance using the optional transition method, which allows for a modified retrospective method of adoption with a cumulative effect adjustment to retained earnings without restating comparable periods. The Company also elected the relief package of practical expedients for which there is no requirement to reassess existence of leases, their classification, and initial direct costs as well as an exemption for short-term leases with a term of less than one year, whereby the Company did not recognize a lease liability or right-of-use asset on the consolidated balance sheet but instead will recognize lease payments as an expense over the lease term as appropriate. See Note 6, Right-of-Use Lease Assets and Lease Liabilities, for additional information related to the Company’s right-of-use lease obligations. Recently Issued Accounting Standards Leases - In July 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors-Certain Leases with Variable Lease Payments (“ASU 2021-05”), that amends lease classification requirements for lessors. In accordance with ASU 2021-05, lessors should classify and account for a lease that have variable lease payments that do not depend on a reference index rate as an operating lease if both of the following criteria are met: i) the lease would have been classified as a sales-type lease or a direct financing lease under the previous lease classification criteria and ii) sales-type or direct financing lease classification would result in a Day 1 loss. ASU 2021-05 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. The Company has evaluated the impact this standard will have on its results of operations, financial position or disclosures, and it is not expected to have a material impact. Presently, the Company is not aware of any other changes to the Accounting Standards Codification that will have a material impact on the Company’s present or future financial position or results of operations.

Summary of Significant Accounting Policies (Policies)

Nature of Operations and Principles of Consolidation

Simmons First National Corporation (“Company”) is a Mid-South financial holding company headquartered in Pine Bluff, Arkansas, and the parent company of Simmons Bank, an Arkansas state-chartered bank that has been in operation since 1903 (“Simmons Bank” or the “Bank”). Simmons First Insurance Services, Inc. and Simmons First Insurance Services of TN, LLC are wholly-owned subsidiaries of Simmons Bank and are insurance agencies that offer various lines of personal and corporate insurance coverage to individual and commercial customers. The Company, through its subsidiaries, offers, among other things, consumer, real estate and commercial loans; checking, savings and time deposits; and specialized products and services (such as credit cards, trust and fiduciary services, investments, agricultural finance lending, equipment lending, insurance and Small Business Administration (“SBA”) lending) from approximately 199 financial centers as of December 31, 2021, located throughout market areas in Arkansas, Kansas, Missouri, Oklahoma, Tennessee and Texas.

The consolidated financial statements include the accounts of the Company and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.

Simmons Bank is an Arkansas state-chartered bank and a member of the Federal Reserve System through the Federal Reserve Bank of St. Louis. Due to the Company’s typical acquisition process, there may be brief periods of time during which the Company may operate another subsidiary bank that the Company acquired through a merger with a target bank holding company as a separate subsidiary while preparing for the merger and integration of that subsidiary bank into Simmons Bank. However, it is the Company’s intent to generally maintain Simmons Bank as the Company’s sole subsidiary bank.

Operating Segments

Operating segments are components of an enterprise about which separate financial information is available that is regularly evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company is organized on a divisional basis, with divisions grouped based on community and metro markets located within the Company’s footprint. Each of the divisions, as well as their respective groups, provide a group of similar community banking services, including such products and services as loans; time deposits, checking and savings accounts; treasury management, personal and corporate trust services; credit cards; investment management; insurance; and securities and investment services. Loan products include consumer, real estate, commercial, agricultural, equipment, warehouse lending and SBA lending. The individual bank divisions have similar operating and economic characteristics. While the chief operating decision maker monitors the revenue streams of the various products, services, branch locations, divisions and groups, operations are managed, financial performance is evaluated, and management makes decisions on how to allocate resources, on a Company-wide basis. Accordingly, the divisions and their respective groups are considered by management to be aggregated into one reportable operating segment.

The Company also considers its trust, investment and insurance services to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under Accounting Standards Codification (“ASC”) Topic 280-10-50-12.

Use of Estimates

The preparation of financial statements, in accordance with US GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income items and expenses and disclosure of contingent assets and liabilities. The estimates and assumptions used in the accompanying consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the consolidated financial statements and actual results may differ from these estimates. Such estimates include, but are not limited to, the Company’s allowance for credit losses.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of acquired loans. Management obtains independent appraisals for significant properties in connection with the determination of the allowance for credit losses and the valuation of foreclosed assets.

Reclassifications

During 2021, certain debit and credit card transaction fees were reclassified from non-interest expense to non-interest income. These transaction fees, as well as additional certain prior year amounts, have been reclassified to conform to the current year financial statement presentation. These changes and reclassifications did not impact previously reported net income or comprehensive income and were not material to the consolidated financial statements.

During 2020, the Company moved equity securities from the available-for-sale investment securities into other assets as well as the related income which moved from interest income to non-interest income. The change had no impact on net income.

Various items within the accompanying consolidated financial statements for previous years have been reclassified to provide more comparative information. These reclassifications were not material to the consolidated financial statements.

Cash Equivalents

The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. For purposes of the consolidated statements of cash flows, cash and cash equivalents are considered to include cash and non-interest bearing balances due from banks, interest bearing balances due from banks and federal funds sold and securities purchased under agreements to resell. At December 31, 2021, nearly all of the interest-bearing and non-interest bearing deposits were uninsured with nearly all of these balances held at the Federal Reserve Bank.

Investment Securities and Allowance for Credit Losses - Investment Securities

Investment Securities

Held-to-maturity securities (“HTM”), which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant effective yield method over the estimated life of the security. Prepayments are anticipated for mortgage-backed and SBA securities. Premiums on callable securities are amortized to their earliest call date.

Available-for-sale securities (“AFS”), which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Realized gains and losses, based on specifically identified amortized cost of the individual security, are included in other income. Unrealized gains and losses are recorded, net of related income tax effects, in stockholders’ equity. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant effective yield method over the estimated life of the security. Prepayments are anticipated for mortgage-backed and SBA securities. Premiums on callable securities are amortized to their earliest call date.

Trading securities, if any, which include any security held primarily for near-term sale, are carried at fair value. Gains and losses on trading securities are included in other income.

Allowance for Credit Losses - Investment Securities

Allowance for Credit Losses - HTM Securities - The Company measures expected credit losses on HTM securities on a collective basis by major security type, with each type sharing similar risk characteristics. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Company has made the election to exclude accrued interest receivable on HTM securities from the estimate of credit losses and report accrued interest separately on the consolidated balance sheets.

Allowance for Credit Losses - AFS Securities - For AFS securities in an unrealized loss position, the Company first evaluates whether it intends to sell, or whether it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either of these criteria regarding intent or requirement to sell is met, the AFS security amortized cost basis is written down to fair value through income. If the criteria is not met, the Company is required to assess whether the decline in fair value has resulted from credit losses or noncredit-related factors. If the assessment indicates a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists, and an allowance for credit loss is recorded through income as a component of provision for credit loss expense. If the assessment indicates that a credit loss does not exist, the Company records the decline in fair value through other comprehensive income, net of related income tax effects. The Company has made the election to exclude accrued interest receivable on AFS securities from the estimate of credit losses and report accrued interest separately on the consolidated balance sheets. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management

believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met.

Mortgage Loans Held For Sale

Mortgage Loans Held for Sale are carried at fair value which is determined on an aggregate basis. Adjustments to fair value are recognized monthly and reflected in earnings. The Company regularly sells mortgages into the capital markets to mitigate the effects of interest rate volatility during the period from the time an interest rate lock commitment (“IRLC”) is issued until the IRLC funds creating a mortgage loan held for sale and its subsequent sale into the secondary/capital markets. Loan sales are typically executed on a mandatory basis. Under a mandatory commitment, the Company agrees to deliver a specified dollar amount with predetermined terms by a certain date. Generally, the commitment is not loan specific, and any combination of loans can be delivered into the outstanding commitment provided the terms fall within the parameters of the commitment. Upon failure to deliver, the Company is subject to fees based on market movement.

The IRLCs are derivative instruments; their fair values at December 31, 2021 and 2020 were not material. Gains and losses resulting from sales of mortgage loans are recognized when the respective loans are sold to correspondent lenders, investors or aggregators. Gains and losses are determined by the difference between the sale price and the carrying amount in the loans sold, net of discounts collected, or premiums paid. Hedge instruments are, likewise, carried at fair value and associated gains/losses are realized at time of settlement.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-offs are reported at their amortized cost basis, which is the unpaid principal balance outstanding, net of unearned income, deferred loan fees and costs, premiums and discounts associated with acquisition date fair value adjustments on acquired loans, and any direct principal charge-offs. The Company has made a policy election to exclude accrued interest from the amortized cost basis of loans and report accrued interest separately from the related loan balance on the consolidated balance sheets.

For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan.

The accrual of interest on loans, except on certain government guaranteed loans, is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on non-accrual or charged off at an earlier date if collection of principal or interest is considered doubtful.

Discounts and premiums on purchased residential real estate loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method.

Further information regarding accounting policies related to past due loans, non-accrual loans, and troubled-debt restructurings is presented in Note 5, Loans and Allowance for Credit Losses. Additionally, for discussion of the Company’s accounting for acquired loans, see Acquisition Accounting, Loans later in this section.

Allowance for Credit Losses

The allowance for credit losses is a reserve established through a provision for credit losses charged to expense, which represents management’s best estimate of lifetime expected losses based on reasonable and supportable forecasts, historical loss experience, and other qualitative considerations. The allowance, in the judgment of management, is necessary to reserve for expected credit losses and risks inherent in the loan portfolio. The Company’s allowance for credit loss methodology includes reserve factors calculated to estimate current expected credit losses to amortized cost balances over the remaining contractual life of the portfolio, adjusted for prepayments, in accordance with ASC Topic 326-20, Financial Instruments - Credit Losses. Accordingly, the methodology is based on the Company’s reasonable and supportable economic forecasts, historical loss experience, and other qualitative adjustments. Management’s evaluation of the allowance for credit losses is inherently subjective as it requires material estimates. It is management’s practice to review the allowance on a monthly basis, and after considering the factors previously noted, to determine the level of provision made to the allowance.

Loans with similar risk characteristics such as loan type, collateral type, and internal risk ratings are aggregated into homogeneous segments for assessment. Reserve factors are based on estimated probability of default and loss given default for each segment. The estimates are determined based on economic forecasts over the reasonable and supportable forecast period based on projected performance of economic variables that have a statistical relationship with the historical loss experience of the segments. For contractual periods that extend beyond the one-year forecast period, the estimates revert to average historical loss experiences over a one-year period on a straight-line basis.

The Company also includes qualitative adjustments to the allowance based on factors and considerations that have not otherwise been fully accounted for. Qualitative adjustments include, but are not limited to:

•Changes in asset quality - Adjustments related to trending credit quality metrics including delinquency, nonperforming loans, charge-offs, and risk ratings that may not be fully accounted for in the reserve factor.

•Changes in the nature and volume of the portfolio - Adjustments related to current changes in the loan portfolio that are not fully represented or accounted for in the reserve factors.

•Changes in lending and loan monitoring policies and procedures - Adjustments related to current changes in lending and loan monitoring procedures as well as review of specific internal policy compliance metrics.

•Changes in the experience, ability, and depth of lending management and other relevant staff - Adjustments to measure increasing or decreasing credit risk related to lending and loan monitoring management.

•Changes in the value of underlying collateral of collateralized loans - Adjustments related to improving or deterioration of the value of underlying collateral that are not fully captured in the reserve factors.

•Changes in and the existence and effect of any concentrations of credit - Adjustments related to credit risk of specific industries that are not fully captured in the reserve factors.

•Changes in regional and local economic and business conditions and developments - Adjustments related to expected and current economic conditions at a regional or local-level that are not fully captured within the Company’s reasonable and supportable forecast.

•Data imprecisions due to limited historical loss data - Adjustments related to limited historical loss data that is representative of the collective loan portfolio.

Collateral Dependent Loans

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 allowance for credit loss 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 allowance for credit losses may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset.

For a collateral dependent loan, the Company’s evaluation process includes a valuation by appraisal or other collateral analysis adjusted for selling costs, when appropriate. This valuation is compared to the remaining outstanding principal balance of the loan. If a loss is determined to be probable, the loss is included in the allowance for credit losses as a specific allocation. If the loan is not collateral dependent, the measurement of loss is based on the difference between the expected and contractual future cash flows of the loan.

Reserve for Unfunded Commitments

In addition to the allowance for credit losses, the Company has established a reserve for unfunded commitments, classified in other liabilities, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. This reserve is maintained at a level management believes to be sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined quarterly based on methodology similar to the methodology for determining the allowance for credit losses. The allowance for credit loss is reported as a component of accrued interest and other liabilities in the consolidated balance sheets. Adjustments to the allowance are reported in the income statement as a component of the provision for credit losses.

Acquisition Accounting, Loans

The Company accounts for its acquisitions under ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. The fair value for acquired loans at the time of acquisition is based on a variety of factors including discounted expected cash flows, adjusted for estimated prepayments and credit losses. In accordance with ASC 326, the fair value adjustment is recorded as premium or discount to the unpaid principal balance of each acquired loan. Loans that have been identified as having experienced a more-than-insignificant deterioration in credit quality since origination is a purchased credit deteriorated (“PCD”) loan. The net premium or discount on PCD loans is adjusted by the Company’s allowance for credit losses recorded at the time of acquisition. The remaining net premium or discount is accreted or amortized into interest income over the remaining life of the loan using a constant yield method. The net premium or discount on loans that are not classified as PCD (“non-PCD”), that includes credit and non-credit components, is accreted or amortized into interest income over the remaining life of the loan using a constant yield method. The Company then records the necessary allowance for credit losses on the non-PCD loans through provision for credit losses expense.

For further discussion of our acquisition and loan accounting, see Note 2, Acquisitions, and Note 5, Loans and Allowance for Credit Losses.

Trust Assets

Trust assets (other than cash deposits) held by the Company in fiduciary or agency capacities for its customers are not included in the accompanying consolidated balance sheets since such items are not assets of the Company.

Premises and Equipment

Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized by the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Right-of-use lease assets are operating leases with a term greater than one year and are included in premises and equipment.

Foreclosed Assets Held For Sale

Assets acquired by foreclosure or in settlement of debt and held for sale are valued at estimated fair value less estimated cost to sell as of the date of foreclosure. Management evaluates the value of foreclosed assets held for sale periodically and any decreases in the fair value are charged to other expense.

Bank Owned Life Insurance

The Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of non-interest income in the Company’s consolidated statements of income.

Goodwill and Intangible Assets

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be separately distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The Company performs an annual goodwill impairment test, and more than annually if circumstances warrant, in accordance with ASC Topic 350, Intangibles – Goodwill and Other, as amended by Accounting Standards Update (“ASU”) 2011-08 - Testing Goodwill for Impairment. ASC Topic 350 requires that goodwill and intangible assets that have indefinite lives be reviewed for impairment annually, or more frequently if certain conditions occur. Intangible assets with finite lives are amortized over the estimated life of the asset, and are reviewed for impairment whenever events or changes in circumstances indicated that the carrying value may not be recoverable. Impairment losses on recorded goodwill, if any, will be recorded as operating expenses.

Derivative Financial Instruments

The Company may enter into derivative contracts for the purposes of managing exposure to interest rate risk to meet the financing needs of its customers. A derivative instrument is a financial tool which derives its value from the value of some other financial

instrument, variable index, including certain hedging instruments embedded in other contracts. These products are primarily designed to reduce interest rate risk for either the Company or its customers who proactively manage these risks.

The Company records all derivatives on the balance sheet at fair value. In an effort to meet the financing needs of its customers and mitigate the impact of changing interest rates on the fair value of AFS securities, the Company has entered into fair value hedges. Fair value hedges include interest rate swap agreements on fixed rate loans and fixed rate callable AFS securities. To qualify for hedge accounting, derivatives must be highly effective at reducing the risk associated with the exposure being hedged and must be designated as a hedge at the point of inception of the derivative contract.

For derivatives designated as hedging the exposure to changes in the fair value of the hedged item, the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain of the hedging instrument. The fair value hedges are considered to be highly effective and any hedge ineffectiveness was deemed not material. Fair value adjustments related to cash flow hedges are recorded in other comprehensive income and are reclassified to earnings when the hedged transaction is reflected in earnings.

Securities Sold Under Agreements to Repurchase

The Company sells securities under agreements to repurchase to meet customer needs for sweep accounts. At the point funds deposited by customers become investable, those funds are used to purchase securities owned by the Company and held in its general account with the designation of Customers’ Securities. A third party maintains control over the securities underlying overnight repurchase agreements. The securities involved in these transactions are generally U.S. Treasury or Federal Agency issues. Securities sold under agreements to repurchase generally mature on the banking day following that on which the investment was initially purchased and are treated as collateralized financing transactions which are recorded at the amounts at which the securities were sold plus accrued interest. Interest rates and maturity dates of the securities involved vary and are not intended to be matched with funds from customers.

Revenue from Contracts with Customers

ASC Topic 606, Revenue from Contracts with Customers, applies to all contracts with customers to provide goods or services in the ordinary course of business. However, Topic 606 specifically does not apply to revenue related to financial instruments, guarantees, insurance contracts, leases, or nonmonetary exchanges. Given these scope exceptions, interest income recognition and measurement related to loans and investments securities, the Company’s two largest sources of revenue, are not accounted for under Topic 606. Also, the Company does not use Topic 606 to account for gains or losses on its investments in securities, loans, and derivatives due to the scope exceptions.

Certain revenue streams, such as service charges on deposit accounts, gains or losses on the sale of OREO, and trust income, fall under the scope of Topic 606 and the Company must recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. Topic 606 is applied using five steps: 1) identify the contract with the customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company has evaluated the nature of all contracts with customers that fall under the scope of Topic 606 and determined that further disaggregation of revenue from contracts with customers into categories was not necessary. There has not been significant revenue recognized in the current reporting periods resulting from performance obligations satisfied in previous periods. In addition, there has not been a significant change in timing of revenues received from customers.

A description of performance obligations for each type of contract with customers is as follows:

Service charges on deposit accounts – The Company’s primary source of funding comes from deposit accounts with its customers. Customers pay certain fees to access their cash on deposit including, but not limited to, non-transactional fees such as account maintenance, dormancy or statement rendering fees, and certain transaction-based fees such as ATM, wire transfer, overdraft or returned check fees. The Company generally satisfies its performance obligations as services are rendered. The transaction prices are fixed, and are charged either on a periodic basis or based on activity.

Sale of OREO – In the normal course of business, the Company will enter into contracts with customers to sell OREO, which has generally been foreclosed upon by the Company. The Company generally satisfies its performance obligation upon conveyance of property from the Company to the customer, generally by way of an executed agreement. The transaction price is fixed, and on

occasion the Company will finance a portion of the proceeds the customers uses to purchase the property. These properties are generally sold without recourse or warranty.

Wealth Management Fees – The Company enters into contracts with its customers to manage assets for investment, and/or transact on their accounts. The Company generally satisfies its performance obligations as services are rendered. The management fee is a fixed percentage-based fee calculated upon the average balance of assets under management and is charged to customers on a monthly basis.

Bankcard Fee Income

Bankcard Fee Income – Periodic bankcard fees, net of direct origination costs, are recognized as revenue on a straight-line basis over the period the fee entitles the cardholder to use the card.

Income Taxes

The Company accounts for income taxes in accordance with income tax accounting guidance in ASC Topic 740, Income Taxes. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.

Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The Company files consolidated income tax returns with its subsidiaries.

Earnings Per Share

Basic earnings per share are computed based on the weighted average number of shares outstanding during each year. Diluted earnings per share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period.

Stock-Based Compensation

The Company has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and performance stock units. Pursuant to the plans, shares are reserved for future issuance by the Company, upon exercise of stock options or awarding of performance or bonus shares granted to directors, officers and other key employees. In accordance with ASC Topic 718, Compensation – Stock Compensation, the fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses various assumptions. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate.

New Accounting Standards

Recently Adopted Accounting Standards

Reference Rate Reform – In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides relief for companies preparing for discontinuation of interest rates such as LIBOR. LIBOR is a benchmark interest rate referenced in a variety of agreements that are used by numerous entities. On March 5, 2021, the U.K. Financial Conduct Authority (“FCA”) announced that the majority of LIBOR rates will no longer be published after December 31, 2021, although a number of key settings will continue until June 2023, to support the rundown of legacy contracts only. As a result, LIBOR should be discontinued as a reference rate.

Other interest rates used globally could also be discontinued for similar reasons. ASU 2020-04 provides optional expedients and exceptions to contracts, hedging relationships and other transactions affected by reference rate reform. The main provisions for contract modifications include optional relief by allowing the modification as a continuation of the existing contract without additional analysis and other optional expedients regarding embedded features. Optional expedients for hedge accounting permits changes to critical terms of hedging relationships and to the designated benchmark interest rate in a fair value hedge and also provides relief for assessing hedge effectiveness for cash flow hedges. Companies are able to apply ASU 2020-04 immediately; however, the guidance will only be available for a limited time (generally through December 31, 2022). The Company formed a LIBOR Transition Team in 2020, has created standard LIBOR replacement language for new and modified loan notes, and is monitoring the remaining loans with LIBOR rates monthly to ensure progress in updating these loans with acceptable LIBOR replacement language or converting them to other interest rates. The Company has not been offering LIBOR-indexed rates originated by other banks, subject to the Company’s determination that the LIBOR replacement language in the loan documents meets the Company’s standards. Pursuant to the Interagency Statement on LIBOR Transition issued in November 2020, the Company will not enter into any new LIBOR-based credit agreements after December 31, 2021. The adoption of ASU 2020-04 has not had a material impact on the Company’s financial position or results of operations.

In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”), which clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the changes in the interest rates used for margining, discounting, or contract price alignment for derivative instruments that are being implemented as part of the market-wide transition to new reference rates (commonly referred to as the “discounting transition”). ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance and generally can be applied through December 31, 2022. ASU 2021-01 did not have a material impact on the Company’s financial position or results of operations.

Income Taxes – In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), that removes certain exceptions for investments, intraperiod allocations and interim calculations, and adds guidance to reduce complexity in accounting for income taxes. ASU 2019-12 introduces the following new guidance: i) guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination in which book goodwill was recognized or a separate transaction and ii) a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax. Additionally, ASU 2019-12 changes the following current guidance: i) making an intraperiod allocation, if there is a loss in continuing operations and gains outside of continuing operations, ii) determining when a deferred tax liability is recognized after an investor in a foreign entity transitions to or from the equity method of accounting, iii) accounting for tax law changes and year-to-date losses in interim periods, and iv) determining how to apply the income tax guidance to franchise taxes that are partially based on income. ASU 2019-12 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2020. The adoption of ASU 2019-12 did not have a material impact on the Company’s operations, financial position or disclosures.

Fair Value Measurement Disclosures – In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), that eliminates, amends and adds disclosure requirements for fair value measurements. These amendments are part of FASB’s disclosure review project and are expected to reduce costs for preparers while providing more decision-useful information for financial statement users. The eliminated disclosure requirements include the 1) the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy; 2) the policy of timing of transfers between levels of the fair value hierarchy; and 3) the valuation processes for Level 3 fair value measurements. Among other modifications, the amended disclosure requirements remove the term “at a minimum” from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities and clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Under the new disclosure requirements, entities must disclose the changes in

unrealized gains or losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The adoption of ASU 2018-13 did not have a material impact on the Company’s fair value disclosures.

Credit Losses on Financial Instruments – In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires earlier measurement of credit losses, expands the range of information considered in determining expected credit losses and enhances disclosures. The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments replace the incurred loss impairment methodology in current US GAAP with a methodology (the current expected credit losses, or “CECL”, methodology) that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.

The CECL methodology utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to-maturity debt securities and other receivables measured at amortized cost at the time the financial asset is originated or acquired. The allowance for credit losses is adjusted each period for changes in expected lifetime credit losses. This methodology replaces the multiple existing impairment methods in current guidance, which generally require that a loss be incurred before it is recognized. Within the life cycle of a loan or other financial asset, this new guidance will generally result in the earlier recognition of the provision for credit losses and the related allowance for credit losses than current practice. For available-for-sale debt securities that the Company intends to hold and where fair value is less than cost, credit-related impairment, if any, will be recognized through an allowance for credit losses and adjusted each period for changes in credit risk.

The effective date for these amendments is for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In preparation for implementation of ASU 2016-13, the Company formed a cross functional team that assessed its data and system needs and evaluated the potential impact of adopting the new guidance. The Company anticipated a significant change in the processes and procedures to calculate the loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the prior accounting practice that utilized the incurred loss model.

On March 27, 2020, the CARES Act was signed in to law by the President of the United States and allowed the option to temporarily defer or suspend the adoption of ASU 2016-13. During the deferral, a registrant would continue to use the incurred loss model for the allowance for loan and lease losses and would be in accordance with US GAAP. The Company has not elected to temporarily defer the adoption of ASU 2016-13 and adopted the new standard as of January 1, 2020. Upon adoption, the Company recorded an additional allowance for credit losses on loans of approximately $151.4 million and an adjustment to the reserve for unfunded commitments recorded in other liabilities of $24.0 million. The Company also recorded an additional allowance for credit losses on investment securities of $742,000. The impact at adoption was reflected as an adjustment to beginning retained earnings, net of income taxes, in the amount of $128.1 million.

The significant impact to the Company’s allowance for credit losses at the date of adoption was driven by the substantial amount of loans acquired held by the Company. The Company had approximately one third of total loans categorized as acquired at the adoption date with very little reserve allocated to them due to the previous incurred loss impairment methodology. As such, the amount of the CECL adoption impact was greater on the Company when compared to a non-acquisitive bank.

In December 2018, the Federal Reserve, Office of the Comptroller of the Currency and FDIC (collectively, the “agencies”) issued a final rule revising regulatory capital rules in anticipation of the adoption of ASU 2016-13 that provided an option to phase in over a three year period on a straight line basis the day-one impact on earnings and Tier 1 capital (the “CECL Transition Provision”).

In March 2020 and in response to the COVID-19 pandemic, the agencies issued a new regulatory capital rule revising the CECL Transition Provision to delay the estimated impact on regulatory capital stemming from the implementation of ASU 2016-13. The rule provides banking organizations that implement CECL before the end of 2020 the option to delay for two years an estimate of CECL’s effect on regulatory capital, followed by a three-year transition period (the “2020 CECL Transition Provision”). The Company elected to apply the 2020 CECL Transition Provision.

Derivatives and Hedging: Targeted Improvements - In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), that changes both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in order to better align a company’s risk management activities and financial reporting for hedging relationships. In summary, this amendment 1) expands the types of transactions eligible for hedge accounting; 2) eliminates the separate measurement and presentation of hedge ineffectiveness; 3) simplifies the requirements around the assessment of hedge effectiveness; 4) provides companies more time to finalize hedge documentation; and 5) enhances presentation and disclosure requirements. The effective date was for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. All transition requirements and elections should be applied to existing hedging relationships on the date of adoption and the effects should be reflected as of the beginning of the fiscal year of adoption. As part of this new guidance, entities are allowed to designate as the hedged item, an amount that is not expected to be affected by prepayments, defaults or other events affecting the timing and amount of cash flows in a closed portfolio of prepayable financial instruments (this is referred to as the “last-of-layer” method). Under the last-of-layer method, entities are able to reclassify, only at the time of adoption, eligible callable debt securities from held-to-maturity to available-for-sale without tainting its intentions to hold future debt securities to maturity. The available-for-sale security must be reported at fair value and any unrealized gain or loss must be recorded as an adjustment to other comprehensive income upon adoption. The Company evaluated its held-to-maturity portfolio during the first quarter 2019 and identified certain municipal bonds with a fair value of $216.4 million that met the last-of-layer criteria under ASU 2017-12 and as a result, reclassified those to available-for-sale and recorded an unrealized gain of $2.5 million in accumulated other comprehensive income during the first quarter of 2019.

Leases - In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), that establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. The new guidance results in a more consistent representation of the rights and obligations arising from leases by requiring lessees to recognize the lease asset and lease liabilities that arise from leases in the consolidated balance sheet and to disclose qualitative and quantitative information about lease transactions, such as information about variable lease payments and options to renew and terminate leases. The effective date was for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. ASU 2016-02 requires entities to adopt the new lease standard using a modified retrospective transition method, meaning an entity initially applies the new lease standard at the beginning of the earliest period presented in the financial statements. Due to complexities associated with using this method, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to relieve entities of the requirement to present prior comparative years’ results when they adopt the new lease standard and giving entities the option to recognize the cumulative effect of applying the new standard as an adjustment to the opening balance of retained earnings. Adoption of ASU 2016-02 resulted in the recognition of right-of-use assets of $32.8 million and right-of-use liabilities of $32.8 million on the consolidated balance sheet with no material impact to the results of operations. The Company has elected to adopt the guidance using the optional transition method, which allows for a modified retrospective method of adoption with a cumulative effect adjustment to retained earnings without restating comparable periods. The Company also elected the relief package of practical expedients for which there is no requirement to reassess existence of leases, their classification, and initial direct costs as well as an exemption for short-term leases with a term of less than one year, whereby the Company did not recognize a lease liability or right-of-use asset on the consolidated balance sheet but instead will recognize lease payments as an expense over the lease term as appropriate. See Note 6, Right-of-Use Lease Assets and Lease Liabilities, for additional information related to the Company’s right-of-use lease obligations.

Recently Issued Accounting Standards

Leases - In July 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors-Certain Leases with Variable Lease Payments (“ASU 2021-05”), that amends lease classification requirements for lessors. In accordance with ASU 2021-05, lessors should classify and account for a lease that have variable lease payments that do not depend on a reference index rate as an operating lease if both of the following criteria are met: i) the lease would have been classified as a sales-type lease or a direct financing lease under the previous lease classification criteria and ii) sales-type or direct financing lease classification would result in a Day 1 loss. ASU 2021-05 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. The Company has evaluated the impact this standard will have on its results of operations, financial position or disclosures, and it is not expected to have a material impact.

Presently, the Company is not aware of any other changes to the Accounting Standards Codification that will have a material impact on the Company’s present or future financial position or results of operations.
