Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Summary of Significant Accounting Policies	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Business AutoNation, Inc., through its subsidiaries, is one of the largest automotive retailers in the United States. As of December 31, 2022, we owned and operated 343 new vehicle franchises from 247 stores located in the United States, predominantly in major metropolitan markets in the Sunbelt region. Our stores sell 33 different new vehicle brands. The core brands of new vehicles that we sell, representing approximately 89% of the new vehicles that we sold in 2022, are manufactured by Toyota (including Lexus), Honda, BMW, Ford, Mercedes-Benz, General Motors, Stellantis, and Volkswagen (including Audi and Porsche). As of December 31, 2022, we also owned and operated 55 AutoNation-branded collision centers, 13 AutoNation USA used vehicle stores, 4 AutoNation-branded automotive auction operations, 3 parts distribution centers, and an auto finance company. We offer a diversified range of automotive products and services, including new vehicles, used vehicles, “parts and service” (also referred to as “After-Sales”), which includes automotive repair and maintenance services as well as wholesale parts and collision businesses, and automotive “finance and insurance” products (also referred to as “Customer Financial Services”), which include vehicle service and other protection products, as well as the arranging of financing for vehicle purchases through third-party finance sources. We also offer indirect financing on certain vehicles we sell, as well as on installment contracts acquired by our captive finance company through third-party independent dealers. For convenience, the terms “AutoNation,” “Company,” and “we” are used to refer collectively to AutoNation, Inc. and its subsidiaries, unless otherwise required by the context. Our dealership operations are conducted by our subsidiaries. Basis of Presentation The accompanying Consolidated Financial Statements include the accounts of AutoNation, Inc. and its subsidiaries. All of our automotive dealership subsidiaries are indirectly wholly owned by the parent company, AutoNation, Inc. Intercompany accounts and transactions have been eliminated in the consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. We base our estimates and judgments on historical experience and other assumptions that we believe are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. We periodically evaluate estimates and assumptions used in the preparation of the financial statements and make changes on a prospective basis when adjustments are necessary. Such estimates and assumptions affect, among other things, our goodwill, indefinite-lived intangible asset, and long-lived asset valuations; inventory valuation; equity investment valuation; assets held for sale; assessments of variable consideration and related constraints related to retrospective commissions; accruals for chargebacks against revenue recognized from the sale of finance and insurance products; accruals related to self-insurance programs; the allowance for expected credit losses; certain legal proceedings; assessment of the annual income tax expense; deferred income taxes and income tax contingencies; and measurement of performance-based compensation costs. Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less as of the date of purchase to be cash equivalents unless the investments are legally or contractually restricted for more than three months. Under our cash management system, outstanding checks that are in excess of the cash balances at certain banks are included in Accounts Payable in the Consolidated Balance Sheets and changes in these amounts are reflected in operating cash flows in the accompanying Consolidated Statements of Cash Flows. Auto Loans Receivable Auto loans receivable include amounts due from customers related to retail vehicle sales financed through our recently acquired captive auto finance company (“CIG” or “AutoNation Finance”), as well as retail vehicle installment sales contracts acquired through third-party independent dealers. Auto loans receivable are presented net of an allowance for expected credit losses. See Note 5 of the Notes to Consolidated Financial Statements for additional information on our significant accounting policies related to auto loans receivable and the allowance for expected credit losses. Financing and Securitization Transactions Through wholly-owned, bankruptcy-remote, special purpose entities, we utilize warehouse facilities to fund auto loans receivable originated by our auto finance company. Prior to our acquisition, CIG put in place term securitizations to provide long-term funding for certain auto loans receivable initially funded through the warehouse facilities. These securitizations remain in place following the acquisition. In these transactions, a pool of auto loans receivable is sold to a bankruptcy-remote, special purpose entity that, in turn, transfers the receivables to a special purpose securitization trust. The securitization trust issues asset-backed securities, secured or otherwise supported by the transferred receivables, and the proceeds from the sale of the asset-backed securities are used to finance the securitized receivables. We are required to evaluate the term securitization trusts for consolidation. See Note 10 of the Notes to Consolidated Financial Statements for more information on our non-recourse debt and consolidation of variable interest entities. Inventory Inventory consists primarily of new and used vehicles held for sale, valued at the lower of cost or net realizable value using the specific identification method. Cost includes acquisition, reconditioning, dealer installed accessories, and transportation expenses. Our new vehicle inventory costs are generally reduced by manufacturer holdbacks (percentage of either the manufacturer’s suggested retail price or invoice price of a new vehicle that the manufacturer repays to the dealer), incentives, floorplan assistance, and non-reimbursement-based manufacturer advertising assistance. Parts, accessories, and other inventory are valued at the lower of cost or net realizable value. See Note 6 of the Notes to Consolidated Financial Statements for more detailed information about our inventory. Property and Equipment, net Property and equipment are recorded at cost less accumulated depreciation. Expenditures for major additions and improvements are capitalized, while minor replacements, maintenance, and repairs are charged to expense as incurred. In addition, we capitalize interest on borrowings during the active construction period of capital projects. Capitalized interest is added to the cost of the assets and depreciated over the estimated useful lives of the assets. Leased property meeting certain criteria is capitalized as a finance lease right-of-use asset and the present value of the related lease payments is recorded as a liability and included in current and/or long-term debt based on the lease term. When property is retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in Other (Income) Expense, Net (within Operating Income) in the Consolidated Statements of Income. See Note 7 of the Notes to Consolidated Financial Statements for detailed information about our property and equipment. Depreciation is recorded over the estimated useful lives of the assets involved using the straight-line method. Leasehold improvements and finance lease right-of-use assets are amortized to depreciation expense over the estimated useful life of the asset or the respective lease term used in determining lease classification, whichever is shorter. The range of estimated useful lives is as follows: Buildings and improvements 5 to 40 years Furniture, fixtures, and equipment 3 to 10 years We continually evaluate property and equipment, including leasehold improvements, to determine whether events or changes in circumstances have occurred that may warrant revision of the estimated useful life or whether the remaining balance should be evaluated for possible impairment. Such events or changes in circumstances may include a significant decrease in market value, a significant change in the business climate in a particular market, a current expectation that more-likely-than-not a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life, or a current-period operating or cash flow loss combined with historical losses or projected future losses. We use an estimate of the related undiscounted cash flows over the remaining life of the asset (asset group) in assessing whether an asset (asset group) is recoverable. If the asset (asset group) is not recoverable, we determine the fair value of the asset (asset group) based on Level 3 inputs, and measure impairment losses based upon the amount by which the carrying amount of the asset (asset group) exceeds the fair value. If we recognize an impairment loss on a depreciable long-lived asset, the adjusted carrying amount of the asset becomes its new cost basis, which is depreciated over the remaining useful life of that asset. When property and equipment are identified as held for sale, we reclassify the held for sale assets to Other Current Assets and cease recording depreciation. We measure each long-lived asset or disposal group at the lower of its carrying amount or fair value less cost to sell and recognize a loss for any initial adjustment of the long-lived asset’s or disposal group’s carrying amount to fair value less cost to sell in the period the “held for sale” criteria are met. Such valuations include estimations of fair values and incremental direct costs to transact a sale. The fair value measurements for our long-lived assets held for sale are based on Level 3 inputs, which consider information obtained from third-party real estate valuation sources, or, in certain cases, pending agreements to sell the related assets. We recognize an impairment loss if the amount of the asset’s or disposal group’s carrying amount exceeds the asset’s or disposal group’s estimated fair value less cost to sell. Assets held for sale in both continuing operations and discontinued operations are reported in the “Corporate and other” category of our segment information. We had assets held for sale in continuing operations of $5.7 million at December 31, 2022, and $53.3 million at December 31, 2021. We had assets held for sale in discontinued operations of $1.1 million at December 31, 2022, and $1.1 million at December 31, 2021. See Note 20 of the Notes to Consolidated Financial Statements for information about our fair value measurement valuation process and impairment charges that were recorded during 2022, 2021, and 2020. Leases We lease numerous facilities and various types of equipment relating to our operations. See Note 9 of the Notes to Consolidated Financial Statements for a discussion of our significant accounting policies related to leases. Goodwill and Other Intangible Assets, net Goodwill consists of the cost of acquired businesses in excess of the fair value of the net assets acquired. Additionally, other intangible assets are separately recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed, rented, or exchanged, regardless of our intent to do so. Our principal identifiable intangible assets are rights under franchise agreements with vehicle manufacturers. We generally expect our franchise agreements to survive for the foreseeable future and, when the agreements do not have indefinite terms, anticipate routine renewals of the agreements without substantial cost. The contractual terms of our franchise agreements provide for various durations, ranging from one year to no expiration date, and in certain cases, manufacturers have undertaken to renew such franchises upon expiration so long as the dealership is in compliance with the terms of the agreement. However, in general, the states in which we operate have automotive dealership franchise laws that provide that, notwithstanding the terms of any franchise agreement, it is unlawful for a manufacturer to terminate or not renew a franchise unless “good cause” exists. It is generally difficult, outside of bankruptcy, for a manufacturer to terminate or not renew a franchise under these franchise laws, which were designed to protect dealers. In addition, in our experience and historically in the automotive retail industry, dealership franchise agreements are rarely involuntarily terminated or not renewed by the manufacturer outside of bankruptcy. Accordingly, we believe that our franchise agreements will contribute to cash flows for the foreseeable future and have indefinite lives. Other intangible assets are amortized using a straight-line method over their useful lives, generally ranging from three to thirty years. We do not amortize goodwill or franchise rights assets. Goodwill and franchise rights are tested for impairment annually or more frequently when events or changes in circumstances indicate that impairment may have occurred. During 2022 and 2021, we did not record any goodwill or franchise rights impairment charges. See Note 8 of the Notes to Consolidated Financial Statements for more information about our goodwill and other intangible assets and Note 20 of the Notes to Consolidated Financial Statements for information about our annual impairment tests of goodwill and franchise rights. Other Current Assets Other current assets consist of various items, including, among other items, prepaid expenses, contract assets, and deposits. Other current assets also includes restricted cash on deposit in reserve accounts for the benefit of holders of certain non-recourse debt. These funds are not expected to be available to the company or its creditors. Other Assets Other assets consist of various items, including, among other items, service loaner and rental vehicle inventory, net, the cash surrender value of corporate-owned life insurance held in a Rabbi Trust for deferred compensation plan participants, and investments in equity securities. Other Current Liabilities Other current liabilities consist of various items payable within one year including, among other items, accruals for sales taxes, the current portions of finance and insurance chargeback liabilities, operating lease liabilities, contract liabilities, and deferred revenue, customer deposits, accrued expenses, and accrued interest payable. Other Liabilities Other liabilities consist of various items payable beyond one year including, among other items, the long-term portions of deferred compensation obligations, finance and insurance chargeback liabilities, contract liabilities, and self-insurance liabilities. Employee Savings Plans We offer a 401(k) plan to all of our associates and provided a matching contribution to certain associates that participate in the plan of $19.9 million in 2022, $14.3 million in 2021, and $4.5 million in 2020. Effective in April 2020, we suspended matching contributions to the 401(k) plan in light of the uncertain economic conditions resulting from the COVID-19 pandemic. A matching contribution to the 401k plan was reinstated effective January 2021. Employer matching are fully vested immediately upon contribution. We offer a deferred compensation plan (the “Plan”) to provide certain associates and non-employee directors with the opportunity to accumulate assets for retirement on a tax-deferred basis. Participants in the Plan are allowed to defer a portion of their compensation and are fully vested in their respective deferrals and earnings. Participants may choose from a variety of investment options, which determine their earnings credits. Effective in January 2021, we suspended matching contributions to the Plan, which were reinstated effective January 2022. We provided a matching contribution to employee participants in the Plan of $1.3 million for 2022 and $1.5 million for 2020. One-third of the matching contribution is vested and credited to participants on the first day of the subsequent calendar year, and an additional one-third vests and is credited on each of the first and second anniversaries of such date. We may also make discretionary contributions, which vest three years after the effective date of the discretionary contribution. The balances due to participants in the Plan were $107.8 million as of December 31, 2022, and $117.2 million as of December 31, 2021, and are included in Other Current Liabilities and Other Liabilities in the accompanying Consolidated Balance Sheets. Stock-Based Compensation We grant stock-based awards in the form of time-based and performance-based restricted stock units (“RSUs”), which are issued from our treasury stock upon vesting. Compensation cost for RSUs is based on the closing price of our common stock on the date of grant. Prior to 2017, we also granted stock options and restricted stock, which were fully vested as of December 31, 2020. Certain of our equity-based compensation plans contain provisions that provide for vesting of awards upon retirement. Accordingly, compensation cost for time-based RSUs is, and for restricted stock awards and stock options was, recognized on a straight-line basis over the shorter of the stated vesting period or the period until associates become retirement-eligible. Compensation cost for performance-based RSUs is recognized over the requisite service period based on the expected achievement level of the performance goals, which is evaluated over the performance period. We account for forfeitures of stock-based awards as they occur. See Note 15 of the Notes to Consolidated Financial Statements for more information about our stock-based compensation arrangements. Revenue Recognition Revenue consists of the sales of new and used vehicles, sales of parts and automotive services, commissions for the placement of finance and insurance products, and sales of other products. See Note 2 of the Notes to Consolidated Financial Statements for a discussion of our significant accounting policies related to revenue recognition. Insurance Under our self-insurance programs, we retain various levels of aggregate loss limits, per claim deductibles, and claims-handling expenses as part of our various insurance programs, including property and casualty, automobile, workers’ compensation, and employee medical benefits. Costs in excess of this retained risk per claim may be insured under various contracts with third-party insurance carriers. We review our claim and loss history on a periodic basis to assist in assessing our future liability. The ultimate costs of these retained insurance risks are estimated by management and by third-party actuarial evaluation of historical claims experience, adjusted for current trends and changes in claims-handling procedures. See Note 12 of the Notes to Consolidated Financial Statements for more information on our self-insurance liabilities. Manufacturer Incentives and Other Rebates We receive various incentives from manufacturers based on achieving certain objectives, such as specified sales volume targets, as well as other objectives, including maintaining standards of a particular vehicle brand, which may include but are not limited to facility image and design requirements, customer satisfaction survey results, and training standards, among others. These incentives are typically based upon units purchased or sold. These manufacturer incentives are recognized as a reduction of new vehicle cost of sales when earned, generally at the time the related vehicles are sold or upon attainment of the particular program goals, whichever is later. We also receive manufacturer rebates and assistance for holdbacks, floorplan interest, and non-reimbursement-based advertising expenses (described below), which are reflected as a reduction in the carrying value of each vehicle purchased by us. We recognize holdbacks, floorplan interest assistance, non-reimbursement-based advertising rebates, cash incentives, and other rebates received from manufacturers that are tied to specific vehicles as a reduction to cost of sales as the related vehicles are sold. Advertising We generally expense the cost of advertising as incurred, net of earned manufacturer reimbursements for specific advertising costs and other discounts. Advertising expense, net of manufacturer advertising reimbursements, was $184.3 million in 2022, $170.3 million in 2021, and $161.7 million in 2020, and is reflected as a component of Selling, General, and Administrative Expenses in the accompanying Consolidated Statements of Income. Manufacturer advertising rebates that are reimbursements of costs associated with specific advertising expenses are earned in accordance with the respective manufacturers’ reimbursement-based advertising assistance programs, which is typically after we have incurred the corresponding advertising expenses, and are reflected as a reduction of advertising expense. Manufacturer advertising reimbursements classified as an offset to advertising expenses were $58.2 million in 2022, $51.4 million in 2021, and $48.2 million in 2020. All other non-reimbursement-based manufacturer advertising rebates that are not associated with specific advertising expenses are recorded as a reduction of inventory and recognized as a reduction of new vehicle cost of sales in the period the related vehicle is sold. Parts and Service Internal Profit Our parts and service departments recondition the majority of used vehicles acquired by our used vehicle departments and perform preparatory work and accessory installation on new vehicles acquired by our new vehicle departments. The parts and service departments charge the new and used vehicle departments as if they were third parties in order to account for total activity performed by that department. Revenues and costs of sales associated with the internal work performed by our parts and service departments are reflected in our parts and service results in our Consolidated Statements of Income. New and used vehicle revenues and costs of sales are reduced by the amount of the intracompany charge. As a result, the revenues and costs of sales associated with the internal work performed by our parts and service departments are eliminated in consolidation. We also defer internal profit associated with the internal work performed by our parts and service departments on our vehicle inventory until such vehicles have been sold. Income Taxes We file a consolidated federal income tax return. Deferred income taxes have been provided for temporary differences between the recognition of revenue and expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities and their reported amounts in the financial statements. See Note 13 of the Notes to Consolidated Financial Statements for more detailed information related to income taxes. Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding for the period, including vested RSU awards. Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding, noted above, adjusted for the dilutive effect of unvested RSU awards and stock options. See Note 3 of the Notes to Consolidated Financial Statements for more information on the computation of earnings per share.

AutoNation, Inc., through its subsidiaries, is one of the largest automotive retailers in the United States. As of December 31, 2022, we owned and operated 343 new vehicle franchises from 247 stores located in the United States, predominantly in major metropolitan markets in the Sunbelt region. Our stores sell 33 different new vehicle brands. The core brands of new vehicles that we sell, representing approximately 89% of the new vehicles that we sold in 2022, are manufactured by Toyota (including Lexus), Honda, BMW, Ford, Mercedes-Benz, General Motors, Stellantis, and Volkswagen (including Audi and Porsche). As of December 31, 2022, we also owned and operated 55 AutoNation-branded collision centers, 13 AutoNation USA used vehicle stores, 4 AutoNation-branded automotive auction operations, 3 parts distribution centers, and an auto finance company.

We offer a diversified range of automotive products and services, including new vehicles, used vehicles, “parts and service” (also referred to as “After-Sales”), which includes automotive repair and maintenance services as well as wholesale parts and collision businesses, and automotive “finance and insurance” products (also referred to as “Customer Financial Services”), which include vehicle service and other protection products, as well as the arranging of financing for vehicle purchases through third-party finance sources. We also offer indirect financing on certain vehicles we sell, as well as on installment contracts acquired by our captive finance company through third-party independent dealers. For convenience, the terms “AutoNation,” “Company,” and “we” are used to refer collectively to AutoNation, Inc. and its subsidiaries, unless otherwise required by the context. Our dealership operations are conducted by our subsidiaries.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. We base our estimates and judgments on historical experience and other assumptions that we believe are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. We periodically evaluate estimates and assumptions used in the preparation of the financial statements and make changes on a prospective basis when adjustments are necessary. Such estimates and assumptions affect, among other things, our goodwill, indefinite-lived intangible asset, and long-lived asset valuations; inventory valuation; equity investment valuation; assets held for sale; assessments of variable consideration and related constraints related to retrospective commissions; accruals for chargebacks against revenue recognized from the sale of finance and insurance products; accruals related to self-insurance programs; the allowance for expected credit losses; certain legal proceedings; assessment of the annual income tax expense; deferred income taxes and income tax contingencies; and measurement of performance-based compensation costs.

We consider all highly liquid investments with a maturity of three months or less as of the date of purchase to be cash equivalents unless the investments are legally or contractually restricted for more than three months. Under our cash management system, outstanding checks that are in excess of the cash balances at certain banks are included in Accounts

Auto loans receivable include amounts due from customers related to retail vehicle sales financed through our recently acquired captive auto finance company (“CIG” or “AutoNation Finance”), as well as retail vehicle installment sales contracts acquired through third-party independent dealers. Auto loans receivable are presented net of an allowance for expected credit losses. See Note 5 of the Notes to Consolidated Financial Statements for additional information on our significant accounting policies related to auto loans receivable and the allowance for expected credit losses.

Through wholly-owned, bankruptcy-remote, special purpose entities, we utilize warehouse facilities to fund auto loans receivable originated by our auto finance company. Prior to our acquisition, CIG put in place term securitizations to provide long-term funding for certain auto loans receivable initially funded through the warehouse facilities. These securitizations remain in place following the acquisition. In these transactions, a pool of auto loans receivable is sold to a bankruptcy-remote, special purpose entity that, in turn, transfers the receivables to a special purpose securitization trust. The securitization trust issues asset-backed securities, secured or otherwise supported by the transferred receivables, and the proceeds from the sale of the asset-backed securities are used to finance the securitized receivables. We are required to evaluate the term securitization trusts for consolidation. See Note 10 of the Notes to Consolidated Financial Statements for more information on our non-recourse debt and consolidation of variable interest entities.

Inventory consists primarily of new and used vehicles held for sale, valued at the lower of cost or net realizable value using the specific identification method. Cost includes acquisition, reconditioning, dealer installed accessories, and transportation expenses. Our new vehicle inventory costs are generally reduced by manufacturer holdbacks (percentage of either the manufacturer’s suggested retail price or invoice price of a new vehicle that the manufacturer repays to the dealer), incentives, floorplan assistance, and non-reimbursement-based manufacturer advertising assistance. Parts, accessories, and other inventory are valued at the lower of cost or net realizable value. See Note 6 of the Notes to Consolidated Financial Statements for more detailed information about our inventory.

Property and equipment are recorded at cost less accumulated depreciation. Expenditures for major additions and improvements are capitalized, while minor replacements, maintenance, and repairs are charged to expense as incurred. In addition, we capitalize interest on borrowings during the active construction period of capital projects. Capitalized interest is added to the cost of the assets and depreciated over the estimated useful lives of the assets. Leased property meeting certain criteria is capitalized as a finance lease right-of-use asset and the present value of the related lease payments is recorded as a liability and included in current and/or long-term debt based on the lease term. When property is retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in Other (Income) Expense, Net (within Operating Income) in the Consolidated Statements of Income. See Note 7 of the Notes to Consolidated Financial Statements for detailed information about our property and equipment.

Depreciation is recorded over the estimated useful lives of the assets involved using the straight-line method. Leasehold improvements and finance lease right-of-use assets are amortized to depreciation expense over the estimated useful life of the asset or the respective lease term used in determining lease classification, whichever is shorter. The range of estimated useful lives is as follows:

We continually evaluate property and equipment, including leasehold improvements, to determine whether events or changes in circumstances have occurred that may warrant revision of the estimated useful life or whether the remaining balance should be evaluated for possible impairment. Such events or changes in circumstances may include a significant decrease in market value, a significant change in the business climate in a particular market, a current expectation that more-likely-than-not a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life, or a current-period operating or cash flow loss combined with historical losses or projected future losses. We use an estimate of the related undiscounted cash flows over the remaining life of the asset (asset group) in assessing whether an asset (asset group) is recoverable. If the asset (asset group) is not recoverable, we determine the fair value of the asset (asset group) based on Level 3 inputs, and measure impairment losses based upon the amount by which the carrying amount of the asset (asset group) exceeds the fair value. If we recognize an impairment loss on a depreciable long-lived asset, the adjusted carrying amount of the asset becomes its new cost basis, which is depreciated over the remaining useful life of that asset.

When property and equipment are identified as held for sale, we reclassify the held for sale assets to Other Current Assets and cease recording depreciation. We measure each long-lived asset or disposal group at the lower of its carrying amount or fair value less cost to sell and recognize a loss for any initial adjustment of the long-lived asset’s or disposal group’s carrying amount to fair value less cost to sell in the period the “held for sale” criteria are met. Such valuations include estimations of fair values and incremental direct costs to transact a sale. The fair value measurements for our long-lived assets held for sale are based on Level 3 inputs, which consider information obtained from third-party real estate valuation sources, or, in certain cases, pending agreements to sell the related assets. We recognize an impairment loss if the amount of the asset’s or disposal group’s carrying amount exceeds the asset’s or disposal group’s estimated fair value less cost to sell.

Assets held for sale in both continuing operations and discontinued operations are reported in the “Corporate and other” category of our segment information. We had assets held for sale in continuing operations of $5.7 million at December 31, 2022, and $53.3 million at December 31, 2021. We had assets held for sale in discontinued operations of $1.1 million at December 31, 2022, and $1.1 million at December 31, 2021.

Goodwill consists of the cost of acquired businesses in excess of the fair value of the net assets acquired. Additionally, other intangible assets are separately recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed, rented, or exchanged, regardless of our intent to do so.

Our principal identifiable intangible assets are rights under franchise agreements with vehicle manufacturers. We generally expect our franchise agreements to survive for the foreseeable future and, when the agreements do not have indefinite terms, anticipate routine renewals of the agreements without substantial cost. The contractual terms of our franchise agreements provide for various durations, ranging from one year to no expiration date, and in certain cases, manufacturers have undertaken to renew such franchises upon expiration so long as the dealership is in compliance with the terms of the agreement. However, in general, the states in which we operate have automotive dealership franchise laws that provide that, notwithstanding the terms of any franchise agreement, it is unlawful for a manufacturer to terminate or not renew a franchise unless “good cause” exists. It is generally difficult, outside of bankruptcy, for a manufacturer to terminate or not renew a franchise under these franchise laws, which were designed to protect dealers.

We grant stock-based awards in the form of time-based and performance-based restricted stock units (“RSUs”), which are issued from our treasury stock upon vesting. Compensation cost for RSUs is based on the closing price of our common stock on the date of grant. Prior to 2017, we also granted stock options and restricted stock, which were fully vested as of December 31, 2020.

Certain of our equity-based compensation plans contain provisions that provide for vesting of awards upon retirement. Accordingly, compensation cost for time-based RSUs is, and for restricted stock awards and stock options was, recognized on a straight-line basis over the shorter of the stated vesting period or the period until associates become retirement-eligible. Compensation cost for performance-based RSUs is recognized over the requisite service period based on the expected achievement level of the performance goals, which is evaluated over the performance period. We account for forfeitures of stock-based awards as they occur. See Note 15 of the Notes to Consolidated Financial Statements for more information about our stock-based compensation arrangements.

Under our self-insurance programs, we retain various levels of aggregate loss limits, per claim deductibles, and claims-handling expenses as part of our various insurance programs, including property and casualty, automobile, workers’ compensation, and employee medical benefits. Costs in excess of this retained risk per claim may be insured under various contracts with third-party insurance carriers. We review our claim and loss history on a periodic basis to assist in assessing our future liability. The ultimate costs of these retained insurance risks are estimated by management and by third-party actuarial evaluation of historical claims experience, adjusted for current trends and changes in claims-handling procedures. See Note 12 of the Notes to Consolidated Financial Statements for more information on our self-insurance liabilities.

We receive various incentives from manufacturers based on achieving certain objectives, such as specified sales volume targets, as well as other objectives, including maintaining standards of a particular vehicle brand, which may include but are not limited to facility image and design requirements, customer satisfaction survey results, and training standards, among others. These incentives are typically based upon units purchased or sold. These manufacturer incentives are recognized as a reduction of new vehicle cost of sales when earned, generally at the time the related vehicles are sold or upon attainment of the particular program goals, whichever is later.

We also receive manufacturer rebates and assistance for holdbacks, floorplan interest, and non-reimbursement-based advertising expenses (described below), which are reflected as a reduction in the carrying value of each vehicle purchased by us. We recognize holdbacks, floorplan interest assistance, non-reimbursement-based advertising rebates, cash incentives, and other rebates received from manufacturers that are tied to specific vehicles as a reduction to cost of sales as the related vehicles are sold.

Manufacturer advertising rebates that are reimbursements of costs associated with specific advertising expenses are earned in accordance with the respective manufacturers’ reimbursement-based advertising assistance programs, which is typically after we have incurred the corresponding advertising expenses, and are reflected as a reduction of advertising expense. Manufacturer advertising reimbursements classified as an offset to advertising expenses were $58.2 million in 2022, $51.4 million in 2021, and $48.2 million in 2020. All other non-reimbursement-based manufacturer advertising rebates that are not associated with specific advertising expenses are recorded as a reduction of inventory and recognized as a reduction of new vehicle cost of sales in the period the related vehicle is sold.

Our parts and service departments recondition the majority of used vehicles acquired by our used vehicle departments and perform preparatory work and accessory installation on new vehicles acquired by our new vehicle departments. The parts and service departments charge the new and used vehicle departments as if they were third parties in order to account for total activity performed by that department. Revenues and costs of sales associated with the internal work performed by our parts and service departments are reflected in our parts and service results in our Consolidated Statements of Income. New and used vehicle revenues and costs of sales are reduced by the amount of the intracompany charge. As a result, the revenues and costs of sales associated with the internal work performed by our parts and service departments are eliminated in consolidation. We also defer internal profit associated with the internal work performed by our parts and service departments on our vehicle inventory until such vehicles have been sold.

We file a consolidated federal income tax return. Deferred income taxes have been provided for temporary differences between the recognition of revenue and expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities and their reported amounts in the financial statements. See Note 13 of the Notes to Consolidated Financial Statements for more detailed information related to income taxes.

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding for the period, including vested RSU awards. Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding, noted above, adjusted for the dilutive effect of unvested RSU awards and stock options. See Note 3 of the Notes to Consolidated Financial Statements for more information on the computation of earnings per share.
