Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for interim periods are not necessarily indicative of actual results achieved for full fiscal years. The consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements at that date but does not include all the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2023 for Credit Acceptance Corporation (the “Company”, “Credit Acceptance”, “we”, “our” or “us”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. We have evaluated events and transactions occurring subsequent to the consolidated balance sheet date of September 30, 2024 for items that could potentially be recognized or disclosed in these financial statements. We did not identify any items that would require disclosure in or adjustment to the consolidated financial statements. Reclassification Certain amounts for prior periods have been reclassified to conform to the current presentation.

Description Of Business [Abstract]
Description of Business	DESCRIPTION OF BUSINESS We make vehicle ownership possible by providing innovative financing solutions that enable automobile dealers to sell vehicles to consumers regardless of their credit history. Our financing programs are offered through a nationwide network of automobile dealers who benefit from sales of vehicles to consumers who otherwise could not obtain financing; from repeat and referral sales generated by these same customers; and from sales to customers responding to advertisements for our financing programs, but who actually end up qualifying for traditional financing. Without our financing programs, consumers are often unable to purchase vehicles or they purchase unreliable ones. Further, as we report to the three national credit reporting agencies, an important ancillary benefit of our programs is that we provide consumers with an opportunity to improve their lives by improving their credit score and move on to more traditional sources of financing. We refer to automobile dealers who participate in our programs and who share our desire to provide an opportunity to consumers to improve their lives as “Dealers.” Upon enrollment in our financing programs, the Dealer enters into a Dealer servicing agreement with us that defines the legal relationship between Credit Acceptance and the Dealer. The Dealer servicing agreement assigns the responsibilities for administering, servicing, and collecting the amounts due on retail installment contracts (referred to as “Consumer Loans”) from the Dealers to us. We are an indirect lender from a legal perspective, meaning the Consumer Loan is originated by the Dealer and assigned to us. The majority of the Consumer Loans assigned to us are made to consumers with impaired or limited credit histories. The following table shows the percentage of Consumer Loans assigned to us with either FICO ® scores below 650 or no FICO ® scores: For the Three Months Ended September 30, For the Nine Months Ended September 30, Consumer Loan Assignment Volume 2024 2023 2024 2023 Percentage of total unit volume with either FICO ® scores below 650 or no FICO ® scores 79.1 % 78.6 % 81.0 % 81.5 % We have two programs: the Portfolio Program and the Purchase Program. Under the Portfolio Program, we advance money to Dealers (referred to as a “Dealer Loan”) in exchange for the right to service the underlying Consumer Loans. Under the Purchase Program, we buy the Consumer Loans from the Dealers (referred to as a “Purchased Loan”) and keep all amounts collected from the consumer. Dealer Loans and Purchased Loans are collectively referred to as “Loans.” The following table shows the percentage of Consumer Loans assigned to us as Dealer Loans and Purchased Loans for each of the last seven quarters: Unit Volume Dollar Volume (1) Three Months Ended Dealer Loans Purchased Loans Dealer Loans Purchased Loans March 31, 2023 72.1 % 27.9 % 68.1 % 31.9 % June 30, 2023 72.4 % 27.6 % 68.6 % 31.4 % September 30, 2023 74.8 % 25.2 % 71.7 % 28.3 % December 31, 2023 77.2 % 22.8 % 75.0 % 25.0 % March 31, 2024 78.2 % 21.8 % 76.6 % 23.4 % June 30, 2024 78.5 % 21.5 % 77.3 % 22.7 % September 30, 2024 79.5 % 20.5 % 78.4 % 21.6 % (1) Represents advances paid to Dealers on Consumer Loans assigned under our Portfolio Program and one-time payments made to Dealers to purchase Consumer Loans assigned under our Purchase Program. Payments of Dealer Holdback (as defined below) and accelerated Dealer Holdback are not included. Portfolio Program As payment for the vehicle, the Dealer generally receives the following: • a down payment from the consumer; • a non-recourse cash payment (“advance”) from us; and • after the advance balance (cash advance and related Dealer Loan fees and costs) has been recovered by us, the cash from payments made on the Consumer Loan, net of certain collection costs and our servicing fee (“Dealer Holdback”). We record the amount advanced to the Dealer as a Dealer Loan, which is classified within Loans receivable in our consolidated balance sheets. Cash advanced to the Dealer is automatically assigned to the Dealer’s open pool of advances. Dealers make an election as to how many Consumer Loans (either 50 or 100) will be assigned to an open pool before it is closed, and subsequent advances are assigned to a new pool. Unless we receive a request from the Dealer to keep a pool open, we automatically close each pool based on the Dealer’s election. All advances within a Dealer’s pool are secured by the future collections on the related Consumer Loans assigned to the pool. For Dealers with more than one pool, the pools are cross-collateralized so the performance of other pools is considered in determining eligibility for Dealer Holdback. We perfect our security interest with respect to the Dealer Loans by obtaining control or taking possession of the Consumer Loans, which list us as lien holder on the vehicle title. The Dealer servicing agreement provides that collections received by us during a calendar month on Consumer Loans assigned by a Dealer are applied on a pool-by-pool basis as follows: • first, to reimburse us for certain collection costs; • second, to pay us our servicing fee, which generally equals 20% of collections; • third, to reduce the aggregate advance balance and to pay any other amounts due from the Dealer to us; and • fourth, to the Dealer as payment of Dealer Holdback. If the collections on Consumer Loans from a Dealer’s pool are not sufficient to repay the advance balance and any other amounts due to us, the Dealer will not receive Dealer Holdback. Certain events may also result in Dealers forfeiting their rights to Dealer Holdback, including becoming inactive before assigning 100 Consumer Loans. Dealers have an opportunity to receive an accelerated Dealer Holdback payment each time a pool of Consumer Loans is closed. The amount paid to the Dealer is calculated using a formula that considers the number of Consumer Loans assigned to the pool and the related forecasted collections and advance balance. Since typically the combination of the advance and the consumer’s down payment provides the Dealer with a cash profit at the time of sale, the Dealer’s risk in the Consumer Loan is limited. We cannot demand repayment of the advance from the Dealer except in the event the Dealer is in default of the Dealer servicing agreement. Advances are made only after the consumer and Dealer have signed a Consumer Loan contract, we have received the executed Consumer Loan contract and supporting documentation in either physical or electronic form, and we have approved all of the related stipulations for funding. For accounting purposes, the transactions described under the Portfolio Program are not considered to be loans to consumers. Instead, our accounting reflects that of a lender to the Dealer. The classification as a Dealer Loan for accounting purposes is primarily a result of (1) the Dealer’s financial interest in the Consumer Loan and (2) certain elements of our legal relationship with the Dealer. Purchase Program The Purchase Program differs from our Portfolio Program in that the Dealer receives a one-time payment from us at the time of assignment to purchase the Consumer Loan instead of a cash advance at the time of assignment and future Dealer Holdback payments. For accounting purposes, the transactions described under the Purchase Program are considered to be originated by the Dealer and then purchased by us. Program Enrollment Dealers are granted access to our Portfolio Program upon enrollment. Access to the Purchase Program is typically only granted to Dealers that meet one of the following: • assigned at least 50 Consumer Loans under the Portfolio Program; • franchise dealership; or • independent dealership that meets certain criteria upon enrollment. Seasonality Our business is seasonal with peak Consumer Loan assignments and collections occurring during the first quarter of the year. This seasonality has a material impact on our interim results, as we are required to recognize a significant provision for credit losses expense at the time of assignment. For additional information, see Note 3.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business Segment Information We currently operate in one reportable segment which represents our core business of offering innovative financing solutions that enable automobile dealers to sell vehicles to consumers regardless of their credit history. The consolidated financial statements reflect the financial results of our one reportable operating segment. Cash and Cash Equivalents and Restricted Cash and Cash Equivalents Cash equivalents consist of readily marketable securities with original maturities at the date of acquisition of three months or less. As of September 30, 2024 and December 31, 2023, we had $158.6 million and $12.8 million, respectively, in cash and cash equivalents that were not insured by the Federal Deposit Insurance Corporation (“FDIC”). Restricted cash and cash equivalents consist of cash pledged as collateral for secured financings and cash held in a trust for future vehicle service contract claims. As of September 30, 2024 and December 31, 2023, we had $551.8 million and $453.7 million, respectively, in restricted cash and cash equivalents that were not insured by the FDIC. The following table provides a reconciliation of cash and cash equivalents and restricted cash and cash equivalents reported in our consolidated balance sheets to the total shown in our consolidated statements of cash flows: (In millions) As of September 30, 2024 December 31, 2023 September 30, 2023 December 31, 2022 Cash and cash equivalents $ 159.7 $ 13.2 $ 3.1 $ 7.7 Restricted cash and cash equivalents 556.6 457.7 435.1 410.0 Total cash and cash equivalents and restricted cash and cash equivalents $ 716.3 $ 470.9 $ 438.2 $ 417.7 Restricted Securities Available for Sale Restricted securities available for sale consist of amounts held in a trust for future vehicle service contract claims. We determine the appropriate classification of our investments in debt securities at the time of purchase and reevaluate such determinations at each balance sheet date. Debt securities for which we do not have the intent or ability to hold to maturity are classified as available for sale, and stated at fair value with unrealized gains and losses, net of income taxes included in the determination of comprehensive income and reported as a component of shareholders’ equity. Loans Receivable and Allowance for Credit Losses Consumer Loan Assignment. For legal purposes, a Consumer Loan is considered to have been assigned to us after the following has occurred: • the consumer and Dealer have signed a Consumer Loan contract; and • we have received the executed Consumer Loan contract and supporting documentation in either physical or electronic form. For accounting and financial reporting purposes, a Consumer Loan is considered to have been assigned to us after the following has occurred: • the Consumer Loan has been legally assigned to us; and • we have made a funding decision and generally have provided funding to the Dealer in the form of either an advance under the Portfolio Program or one-time purchase payment under the Purchase Program. Portfolio Segments and Classes. Our Loan portfolio consists of two portfolio segments: Dealer Loans and Purchased Loans. Our determination is based on the following: • We have two financing programs: the Portfolio Program and the Purchase Program. We are considered to be a lender to Dealers for Consumer Loans assigned under the Portfolio Program and a purchaser of Consumer Loans assigned under the Purchase Program. • The Portfolio Program and the Purchase Program have different levels of risk in relation to credit losses. Under the Portfolio Program, the impact of negative variances in Consumer Loan performance is mitigated by Dealer Holdback and the cross-collateralization of Consumer Loan assignments. Under the Purchase Program, we are impacted by the full amount of negative variances in Consumer Loan performance. • Our business model is narrowly focused on Consumer Loan assignments from one industry with expected cash flows that are significantly lower than the contractual cash flows owed to us due to credit quality. We do not believe that it is meaningful to disaggregate our Loan portfolio beyond the Dealer Loans and Purchased Loans portfolio segments. Each portfolio segment consists of one class of Consumer Loan assignments, which is Consumer Loans originated by Dealers to finance purchases of vehicles and related ancillary products by consumers with impaired or limited credit histories. Our determination is based on the following: • All of the Consumer Loans assigned to us have similar risk characteristics in relation to the categorization of borrowers, type of financing receivable, industry sector, and type of collateral. • We only accept Consumer Loan assignments from Dealers located within the United States. Recognition and Measurement Policy. On January 1, 2020, we adopted Accounting Standards Update 2016-13, Measurement of Credit Losses on Financial Instruments, which is known as the current expected credit loss model, or CECL. Loans outstanding prior to the adoption date are no longer material to our consolidated financial statements. Consumer Loans assigned to us on or subsequent to January 1, 2020 are accounted for as originated financial assets (“Originated Method”). Under the Originated Method, at the time of assignment, we: • calculate the effective interest rate based on contractual future net cash flows; • record a Loan receivable equal to the advance paid to the Dealer under the Portfolio Program or purchase price paid to the Dealer under the Purchase Program; and • record an allowance for credit losses equal to the difference between the initial Loan receivable balance and the present value of expected future net cash flows discounted at the effective interest rate. The initial allowance for credit losses is recognized as provision for credit losses expense. The effective interest rate and initial allowance for credit losses are significantly higher for Consumer Loans assigned under the Purchase Program than for Consumer Loans assigned under the Portfolio Program, as contractual net cash flows exceed expected net cash flows by a significantly greater margin under the Purchase Program. Under the Purchase Program, we retain all contractual collections that exceed our initial expectations. Under the Portfolio Program, contractual collections that exceed our initial expectations are substantially offset by additional Dealer Holdback payments. Under the Originated Method, for each reporting period subsequent to assignment, we: • recognize finance charge revenue using the effective interest rate that was calculated at the time of assignment based on contractual future net cash flows; and • adjust the allowance for credit losses so that the net carrying amount of each Loan equals the present value of expected future net cash flows discounted at the effective interest rate. The adjustment to the allowance for credit losses is recognized as either provision for credit losses expense or a reversal of provision for credit losses expense. Loans Receivable . Amounts advanced to Dealers for Consumer Loans assigned under the Portfolio Program are recorded as Dealer Loans and are aggregated by Dealer for purposes of recognizing revenue and measuring credit losses. Amounts paid to Dealers for Consumer Loans assigned under the Purchase Program are recorded as Purchased Loans and, for purposes of recognizing revenue and measuring credit losses, are not aggregated. The outstanding balance of each Loan included in Loans receivable is comprised of the following: • cash paid to the Dealer (or to third-party ancillary product providers on the Dealer’s behalf) for the Consumer Loan assignment (advance under the Portfolio Program or one-time purchase payment under the Purchase Program); • finance charges; • Dealer Holdback payments; • accelerated Dealer Holdback payments; • recoveries; • transfers in; • less: collections (net of certain collection costs); • less: write-offs; and • less: transfers out. Under our Portfolio Program, certain events may result in Dealers forfeiting their rights to Dealer Holdback. We transfer the Dealer’s outstanding Dealer Loan balance and the related allowance for credit losses balance to Purchased Loans in the period this forfeiture occurs. We aggregate these Purchased Loans by Dealer for purposes of recognizing revenue and measuring credit losses. Allowance for Credit Losses. The outstanding balance of the allowance for credit losses of each Loan represents the amount required to reduce net carrying amount of Loans (Loans receivable less allowance for credit losses) to the present value of expected future net cash flows discounted at the effective interest rate. Expected future net cash flows for Dealer Loans are comprised of expected future collections on the assigned Consumer Loans, less any expected future Dealer Holdback payments. Expected future net cash flows for Purchased Loans are comprised of expected future collections on the assigned Consumer Loans. Expected future collections are forecasted for each individual Consumer Loan based on the historical performance of Consumer Loans with similar characteristics, adjusted for recent trends in payment patterns. Our forecast of expected future collections includes estimates for prepayments and post-contractual-term cash flows. Unless the consumer is no longer contractually obligated to pay us, we forecast future collections on each Consumer Loan for a 120 month period after the origination date. Expected future Dealer Holdback payments are forecasted for each individual Dealer based on the expected future collections and current advance balance of each Dealer Loan. We fully write off the outstanding balances of a Loan and the related allowance for credit losses once we are no longer forecasting any expected future net cash flows on the Loan. Under our partial write-off policy, we write off the amount of the outstanding balances of a Loan and the related allowance for credit losses, if any, that exceeds 200% of the present value of expected future net cash flows on the Loan, as we deem this amount to be uncollectable. Credit Quality. The vast majority of the Consumer Loans assigned to us are made to individuals with impaired or limited credit histories. Consumer Loans made to these individuals generally entail a higher risk of delinquency, default, and repossession and higher losses than loans made to consumers with better credit. Since most of our revenue and cash flows are generated from these Consumer Loans, our ability to accurately forecast Consumer Loan performance is critical to our business and financial results. At the time a Consumer Loan is submitted to us for assignment, we forecast future expected cash flows from the Consumer Loan. Based on these forecasts, an advance or one-time purchase payment is made to the related Dealer at a price designed to maximize our economic profit, a non-GAAP financial measure that considers our return on capital, our cost of capital, and the amount of capital invested. We monitor and evaluate the credit quality of Consumer Loans on a monthly basis by comparing our current forecasted collection rates to our initial expectations. We use a statistical model that considers a number of credit quality indicators to estimate the expected collection rate for each Consumer Loan at the time of assignment. The credit quality indicators considered in our model include attributes contained in the consumer’s credit bureau report, data contained in the consumer’s credit application, the structure of the proposed transaction, vehicle information and other factors. We continue to evaluate the expected collection rate for each Consumer Loan subsequent to assignment primarily through the monitoring of consumer payment behavior. Our evaluation becomes more accurate as the Consumer Loans age, as we use actual performance data in our forecast. Since all known, significant credit quality indicators have already been factored into our forecasts and pricing, we are not able to use any specific credit quality indicators to predict or explain variances in actual performance from our initial expectations. Any variances in performance from our initial expectations are a result of Consumer Loans performing differently from historical Consumer Loans with similar characteristics. We periodically adjust our statistical pricing model for new trends that we identify through our evaluation of these forecasted collection rate variances. When overall forecasted collection rates underperform our initial expectations, the decline in forecasted collections has a more adverse impact on the profitability of the Purchased Loans than on the profitability of the Dealer Loans. For Purchased Loans, the decline in forecasted collections is absorbed entirely by us. For Dealer Loans, the decline in the forecasted collections is substantially offset by a decline in forecasted payments of Dealer Holdback. Methodolo gy Changes . During the second quarter of 2024, we applied an adjustment to our methodology for forecasting the amount of future net cash flows from our Loan portfolio, which reduced the forecasted collection rates for Consumer Loans assigned in 2022 through 2024. During the second quarter of 2023, we adjusted our methodology for forecasting the amount and timing of future net cash flows from our Loan portfolio through the utilization of more recent Consumer Loan performance and Consumer Loan prepayment data. For additional information, see Note 6. For the three and nine months ended September 30, 2024 and 2023, we did not make any other methodology changes for Loans that had a material impact on our financial statements. Finance Charges Sources of Revenue. Finance charges is comprised of: (1) interest income earned on Loans; (2) administrative fees earned from ancillary products; (3) program fees charged to Dealers under the Portfolio Program; (4) Consumer Loan assignment fees charged to Dealers; and (5) direct origination costs incurred on Dealer Loans. We provide Dealers the ability to offer vehicle service contracts to consumers through our relationships with Third-Party Providers (“TPPs”). A vehicle service contract provides the consumer protection by paying for the repair or replacement of certain components of the vehicle in the event of a mechanical failure. The retail price of the vehicle service contract is included in the principal balance of the Consumer Loan. The wholesale cost of the vehicle service contract is paid to the TPP, net of an administrative fee retained by us. The difference between the wholesale cost and the retail price to the consumer is paid to the Dealer as a commission. Under the Portfolio Program, the wholesale cost of the vehicle service contract and the commission paid to the Dealer are charged to the Dealer’s advance balance. TPPs process claims on vehicle service contracts that are underwritten by third-party insurers. We bear the risk of loss for claims on certain vehicle service contracts that are reinsured by us. We market the vehicle service contracts directly to Dealers. We provide Dealers the ability to offer Guaranteed Asset Protection (“GAP”) to consumers through our relationships with TPPs. GAP provides the consumer protection by paying the difference between the loan balance and the amount covered by the consumer’s insurance policy in the event of a total loss of the vehicle due to severe damage or theft. The retail price of GAP is included in the principal balance of the Consumer Loan. The wholesale cost of GAP is paid to the TPP, net of an administrative fee retained by us. The difference between the wholesale cost and the retail price to the consumer is paid to the Dealer as a commission. Under the Portfolio Program, the wholesale cost of GAP and the commission paid to the Dealer are charged to the Dealer’s advance balance. TPPs process claims on GAP contracts that are underwritten by third-party insurers. Program fees represent monthly fees charged to Dealers for access to our Credit Approval Processing System (“CAPS”); administration, servicing, and collection services offered by us; documentation related to or affecting our program; and all tangible and intangible property owned by Credit Acceptance. We charge a monthly fee of $599 to Dealers participating in our Portfolio Program and we collect it from future Dealer Holdback payments. Recognition Policy. We recognize finance charges under the interest method such that revenue is recognized on a level-yield basis over the life of the Loan. We calculate finance charges on a monthly basis by applying the effective interest rate of the Loan to the net carrying amount of the Loan (Loan receivable less the related allowance for credit losses). The effective interest rate is based on contractual future net cash flows. We report the change in the present value of credit losses attributable to the passage of time as a reduction to finance charges. Accordingly, we allocate finance charges recognized on each Loan between the Loan receivable and the related allowance for credit losses. The amount of finance charges allocated to the Loan receivable is equal to the effective interest rate applied to the Loans receivable balance. The reduction of finance charges allocated to the allowance for credit losses is equal to the effective interest rate applied to the allowance for credit losses balance. Reinsurance Our wholly owned subsidiary VSC Re Company (“VSC Re”) is engaged in the business of reinsuring coverage under vehicle service contracts sold to consumers by Dealers on vehicles financed by us. VSC Re currently reinsures vehicle service contracts that are offered through one of our TPPs. Vehicle service contract premiums, which represent the selling price of the vehicle service contract to the consumer, less fees and certain administrative costs, are contributed to a trust account controlled by VSC Re. These premiums are used to fund claims covered under the vehicle service contracts. VSC Re is a bankruptcy remote entity. As such, our exposure to fund claims is limited to the trust assets controlled by VSC Re and our net investment in VSC Re. Premiums from the reinsurance of vehicle service contracts are recognized over the life of the policy in proportion to expected costs of servicing those contracts. Expected costs are determined based on our historical claims experience. Claims are expensed through a provision for claims in the period the claim was incurred. Capitalized acquisition costs are comprised of premium taxes and are amortized as general and administrative expense over the life of the contracts in proportion to premiums earned. We have consolidated the trust within our financial statements based on our determination of the following: • We have a variable interest in the trust. We have a residual interest in the assets of the trust, which is variable in nature, given that it increases or decreases based upon the actual loss experience of the related service contracts. In addition, VSC Re is required to absorb any losses in excess of the trust’s assets. • The trust is a variable interest entity. The trust has insufficient equity at risk as no parties to the trust were required to contribute assets that provide them with any ownership interest. • We are the primary beneficiary of the trust. We control the amount of premiums written and placed in the trust through Consumer Loan assignments under our Programs, which is the activity that most significantly impacts the economic performance of the trust. We have the right to receive benefits from the trust that could potentially be significant. In addition, VSC Re has the obligation to absorb losses of the trust that could potentially be significant. New Accounting Updates Not Yet Adopted Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the “Codification”). The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If, by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. We are currently evaluating the impact the adoption of ASU 2023-06 will have on our consolidated financial statements and related disclosures. Improvements to Reportable Segment Disclosures. In November 2023, the FASB issued ASU 2023-07, which enhances the required disclosures for operating segments in our annual and interim consolidated financial statements. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted but we have not yet adopted ASU 2023-07. We are currently evaluating the impact the adoption of ASU 2023-07 will have on our consolidated financial statements and related disclosures. Improvements to Income Tax Disclosures. In December 2023, the FASB issued ASU 2023-09, which intends to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments intended to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted, but we have not yet adopted ASU 2023-09. We are currently evaluating the impact the adoption of ASU 2023-09 will have on our consolidated financial statements and related disclosures.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate their value. Cash and Cash Equivalents and Restricted Cash and Cash Equivalents . The carrying amounts approximate their fair value due to the short maturity of these instruments. Restricted Securities Available for Sale. The fair value of U.S. Government and agency securities, corporate bonds, and municipal securities is based on quoted market values in active markets. For asset-backed securities, mortgage-backed securities, and commercial paper, we use model-based valuation techniques for which all significant assumptions are observable in the market. Loans Receivable, net. The fair value is determined by calculating the present value of expected future net cash flows estimated by us by utilizing the discount rate used to calculate the value of our Loans under our non-GAAP floating yield methodology. Revolving Secured Lines of Credit. The fair value is determined by calculating the present value of the debt instrument based on current rates for debt with a similar risk profile and maturity. Secured Financing. The fair value of certain asset-backed secured financings (“Term ABS” financings) is determined using quoted market prices in an active market. For our warehouse facilities and certain other Term ABS financings, the fair values are determined by calculating the present value of each debt instrument based on current rates for debt with similar risk profiles and maturities. Senior Notes. The fair value is determined using quoted market prices in an active market. Mortgage Note. The fair value was determined by calculating the present value of the debt instrument based on current rates for debt with a similar risk profile and maturity. A comparison of the carrying amount and estimated fair value of these financial instruments is as follows: (In millions) As of September 30, 2024 As of December 31, 2023 Carrying Estimated Fair Carrying Estimated Fair Assets Cash and cash equivalents $ 159.7 $ 159.7 $ 13.2 $ 13.2 Restricted cash and cash equivalents 556.6 556.6 457.7 457.7 Restricted securities available for sale 113.9 113.9 93.2 93.2 Loans receivable, net 7,781.5 8,882.3 6,955.3 7,759.1 Liabilities Revolving secured lines of credit $ 1.0 $ 1.0 $ 79.2 $ 79.2 Secured financing 5,257.1 5,360.4 3,990.9 4,025.9 Senior notes 990.8 1,042.8 989.0 1,039.8 Mortgage note — — 8.4 8.4 Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. We group assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates or assumptions that market participants would use in pricing the asset or liability. The following table provides the level of measurement used to determine the fair value for each of our financial instruments measured or disclosed at fair value: (In millions) As of September 30, 2024 Level 1 Level 2 Level 3 Total Fair Value Assets Cash and cash equivalents (1) $ 159.7 $ — $ — $ 159.7 Restricted cash and cash equivalents (1) 556.6 — — 556.6 Restricted securities available for sale (2) 90.7 23.2 — 113.9 Loans receivable, net (1) — — 8,882.3 8,882.3 Liabilities Revolving secured lines of credit (1) $ — $ 1.0 $ — $ 1.0 Secured financing (1) 4,460.2 900.2 — 5,360.4 Senior notes (1) 1,042.8 — — 1,042.8 (In millions) As of December 31, 2023 Level 1 Level 2 Level 3 Total Fair Value Assets Cash and cash equivalents (1) $ 13.2 $ — $ — $ 13.2 Restricted cash and cash equivalents (1) 457.7 — — 457.7 Restricted securities available for sale (2) 75.1 18.1 — 93.2 Loans receivable, net (1) — — 7,759.1 7,759.1 Liabilities Revolving secured lines of credit (1) $ — $ 79.2 $ — $ 79.2 Secured financing (1) 3,225.8 800.1 — 4,025.9 Senior notes (1) 1,039.8 — — 1,039.8 Mortgage note (1) — 8.4 — 8.4 (1) Measured at amortized cost with fair value disclosed.

Consumer Loans assigned in 2022 had continued to underperform our expectations for several quarters. More recently, Consumer Loans assigned in 2023 had also begun exhibiting similar trends of underperformance, although not as severe as Consumer Loans assigned in 2022. During the second quarter of 2024, we determined that we had sufficient Consumer Loan performance experience to estimate the magnitude by which we expected Consumer Loans assigned in 2022 through 2024 would likely underperform our historical collection rates on Consumer Loans with similar characteristics. Accordingly, we applied an adjustment to Consumer Loans assigned in 2022 through 2024 to reduce forecasted collection rates to what we believed the ultimate collection rates would be based on these trends. Changes in the amount and timing of forecasted net cash flows are recognized in the period of change as a provision for credit losses. The implementation of this forecast adjustment during the second quarter of 2024 reduced forecasted net cash flows by $147.2 million, or 1.4%, and increased provision for credit losses by $127.5 million. During the second quarter of 2023, we adjusted our methodology for forecasting the amount and timing of future net cash flows from our Loan portfolio through the utilization of more recent Consumer Loan performance and Consumer Loan prepayment data. We had experienced a decrease in Consumer Loan prepayments to below-average levels and as a result, slowed our forecasted net cash flow timing. Historically, Consumer Loan prepayments have been lower in periods with less availability of consumer credit. Changes in the amount and timing of forecasted net cash flows are recognized in the period of change as a provision for credit losses. The implementation of the adjustment to our forecasting methodology during the second quarter of 2023 reduced forecasted net cash flows by $44.5 million, or 0.5%, and increased provision for credit losses by $71.3 million.

Revolving Secured Lines of Credit We have two revolving secured lines of credit: (1) a $390.0 million revolving secured line of credit facility, to which we refer as our revolving secured line of credit facility, with a commercial bank syndicate and (2) an uncommitted $20.0 million revolving secured line of credit facility, to which we refer as the RTP facility, with a lender for use solely in facilitating payments by the Company through the lender’s real-time payments service. Borrowings under our revolving secured line of credit facility, including any letters of credit issued under the facility, are subject to a borrowing-base limitation. This limitation equals 80% of the value of Loans, as defined in the agreement governing our revolving secured line of credit facility, less a hedging reserve (not exceeding $1.0 million), and the amount of other debt secured by the collateral that secures our revolving secured line of credit facility. Borrowings under our revolving secured line of credit facility are secured by a lien on most of our assets that do not secure obligations under our Warehouse facilities or Term ABS financings. Borrowings under the RTP facility are secured by a lien on the same collateral that secures obligations under our revolving secured line of credit facility. The RTP facility terminates automatically if the lender ceases to be part of the commercial bank syndicate under our revolving secured line of credit facility or if its lending commitments under our revolving secured line of credit facility are terminated. Warehouse Facilities We have five Warehouse facilities with total borrowing capacity of $1,275.0 million. Each of the facilities is with a different lender or group of lenders. Under each Warehouse facility, we can convey Loans to the applicable wholly owned subsidiary in return for cash and/or an increase in the value of our equity in such subsidiary. In turn, each such subsidiary pledges the Loans as collateral to secure financing that will fund the cash portion of the purchase price of the Loans. The financing provided to each such subsidiary under the applicable facility is generally limited to the lesser of 80% of the outstanding balance of the conveyed Loans, as determined in accordance with the applicable agreement, plus certain restricted cash and cash equivalents pledged as collateral, or the facility limit. The financings create indebtedness for which the subsidiaries are liable and which is secured by all the assets of each subsidiary. Such indebtedness is non-recourse to us (other than customary, limited recourse to us in the form of repurchase obligations or indemnification obligations for any violations by us of our representations or obligations as seller, servicer, or custodian), even though we are consolidated for financial reporting purposes with the subsidiaries. Because the subsidiaries are organized as bankruptcy-remote legal entities separate from us, their assets (including the conveyed Loans) are not available to any creditors other than the creditors of the applicable subsidiary. The subsidiaries pay us a monthly servicing fee equal to either 4% or 6%, depending upon the facility, of the collections received with respect to the conveyed Loans. The servicing fee is paid out of the collections. Except for the servicing fee and holdback payments due to Dealers, if a facility is amortizing, we do not have any rights in any portion of such collections until all outstanding principal, accrued and unpaid interest, fees, and other related costs have been paid in full. If a facility is in its revolving period, the applicable subsidiary is entitled to the portion of such collections available after the payment of interest and transaction expenses under the facility, provided that the borrowing base requirements of the facility are satisfied. Term ABS Financings We have wholly owned subsidiaries (the “Funding LLCs”) that have completed secured financing transactions with qualified institutional investors or lenders. In connection with each of these transactions, we conveyed Loans on an arms-length basis to a Funding LLC for cash and the sole membership interest in that Funding LLC. In turn, each Funding LLC, other than the Funding LLCs for the Term ABS 2019-2, 2021-1, 2022-2, and 2023-A financings, conveyed the Loans to the respective trusts that issued notes to qualified institutional investors. The Funding LLCs for the Term ABS 2019-2, 2021-1, 2022-2, and 2023-A financings pledged the Loans for the benefit of their respective lenders. The Term ABS 2021-3, 2021-4, 2023-1, 2023-2, 2023-3, 2023-A, 2023-5, 2024-A, 2024-1, 2024-2, and 2024-3 financings each consist of three classes of notes (or, in the case of the Term ABS 2023-A, three classes of loans), while the Term ABS 2022-1 and Term ABS 2022-3 financings consist of four classes of notes. Each Term ABS financing at the time of issuance has a specified revolving period during which we are likely to convey additional Loans to the applicable Funding LLC. Each Funding LLC (other than the Funding LLCs of the Term ABS 2019-2, 2021-1, 2022-2, and 2023-A financings) will then convey the Loans to its respective trust. At the end of the applicable revolving period, the debt outstanding under each financing will begin to amortize. The Term ABS financings create indebtedness for which the applicable trust or Funding LLC is liable and which is secured by all the assets of the applicable trust or Funding LLC. Such indebtedness is non-recourse to us (other than customary, limited recourse to us in the form of repurchase obligations or indemnification obligations for any violations by us of our representations or obligations as seller, servicer, or custodian), even though we are consolidated for financial reporting purposes with the trusts and the Funding LLCs. Because the trusts and the Funding LLCs are organized as bankruptcy-remote legal entities separate from us, their assets (including the conveyed Loans) are not available to any creditors other than the creditors of the applicable subsidiary. We receive a monthly servicing fee on each financing equal to either 4% or 6%, depending upon the financing, of the collections received with respect to the conveyed Loans. The fee is paid out of the collections. Except for the servicing fee and Dealer Holdback payments due to Dealers, if a Term ABS financing is amortizing, we do not have any rights in any portion of such collections until all outstanding principal, accrued and unpaid interest, fees, and other related costs have been paid in full. If a Term ABS financing is in its revolving period, the applicable trust or Funding LLC is entitled to the portion of such collections available after application of any amounts necessary to acquire additional Loans from us and to pay accrued interest on the debt and any other transaction expenses, provided that any necessary principal payments are made to compensate for certain reductions in the balance of eligible loans or, in the case of the Term ABS 2019-2 financing and Term ABS financings occurring after the Term ABS 2021-3 financing, certain reductions in forecasted collections. In addition, in our capacity as servicer of the Loans, we have a limited right to exercise a “clean-up call” option to purchase Loans from the Funding LLCs and/or the trusts under certain specified circumstances. For those Funding LLCs with a trust, when the trust’s indebtedness is paid in full, either through collections or through a prepayment of the indebtedness, the trust is to pay any remaining collections over to its Funding LLC as the sole beneficiary of the trust. For all Funding LLCs, after the indebtedness is paid in full, any remaining collections will ultimately be available to be distributed to us as the sole member of the respective Funding LLC. Senior Notes On December 19, 2023, we issued $600.0 million aggregate principal amount of 9.250% senior notes due 2028 (the “2028 senior notes”). The 2028 senior notes were issued pursuant to an indenture, dated as of December 19, 2023, among the Company, as issuer, the Company’s subsidiaries Buyers Vehicle Protection Plan, Inc. and Vehicle Remarketing Services, Inc., as guarantors (collectively, the “Guarantors”), and the trustee under the indenture. The 2028 senior notes mature on December 15, 2028 and bear interest at a rate of 9.250% per annum, computed on the basis of a 360-day year composed of twelve 30-day months and payable semi-annually on June 15 and December 15 of each year, beginning on June 15, 2024. We used a portion of the net proceeds from the 2028 senior notes to repurchase or redeem all of the $400.0 million outstanding principal amount of our 5.125% senior notes due 2024 (the “2024 senior notes”), of which $322.3 million was repurchased on December 19, 2023 and the remaining $77.7 million was redeemed on December 31, 2023. We used the remaining net proceeds from the 2028 senior notes for general corporate purposes. During the fourth quarter of 2023, we recognized a pre-tax loss on extinguishment of debt of $1.8 million related to the repurchase and redemption of the 2024 senior notes. On March 7, 2019, we issued $400.0 million aggregate principal amount of 6.625% senior notes due 2026 (the “2026 senior notes”). The 2026 senior notes were issued pursuant to an indenture, dated as of March 7, 2019, among the Company, as issuer, the Guarantors, and the trustee under the indenture. The 2026 senior notes mature on March 15, 2026 and bear interest at a rate of 6.625% per annum, computed on the basis of a 360-day year composed of twelve 30-day months and payable semi-annually on March 15 and September 15 of each year, beginning on September 15, 2019. We used the net proceeds from the offering of the 2026 senior notes for general corporate purposes, including repayment of outstanding borrowings under our revolving secured line of credit facility. The 2028 senior notes and 2026 senior notes (the “senior notes”) are guaranteed on a senior basis by the Guarantors, which are also guarantors of obligations under our revolving secured line of credit facility. Other existing and future subsidiaries of ours may become guarantors of the senior notes in the future. The indentures for the senior notes provide for a guarantor of the senior notes to be released from its obligations under its guarantee of the senior notes under specified circumstances. Mortgage Note We had a $9.0 million mortgage note with a commercial bank that was secured by a first mortgage lien on a building acquired by us and an assignment of all leases, rents, revenues, and profits under all present and future leases of the building. The note was paid off in full during the second quarter of 2024 in connection with the sale of the related building. Debt Covenants As of September 30, 2024, we were in compliance with our covenants under our revolving secured line of credit facility and our Warehouse facilities, including those that require the maintenance of certain financial ratios and other financial conditions. These covenants require a minimum ratio of (1) our net earnings, adjusted for specified items, before income taxes, depreciation, amortization, and fixed charges to (2) our fixed charges, as defined in the agreements. These covenants also limit the maximum ratio of our funded debt less unrestricted cash and cash equivalents to tangible net worth. Some of these covenants may indirectly limit the repurchase of common stock or payment of dividends on common stock. Our Warehouse facilities also contain covenants that measure the performance of the conveyed assets. Our Term ABS financings also contain covenants that measure the performance of the conveyed assets. As of September 30, 2024, we were in compliance with our covenants under our Term ABS financings, the senior notes indentures, and the RTP facility.

Income Taxes	INCOME TAXES A reconciliation of the U.S. federal statutory income tax rate to our effective income tax rate is as follows: For the Three Months Ended For the Nine Months Ended 2024 2023 2024 2023 U.S. federal statutory income tax rate 21.0 % 21.0 % 21.0 % 21.0 % State and local income taxes 3.6 % 4.3 % 6.6 % 2.8 % Non-deductible executive compensation expense 1.4 % 1.2 % 2.9 % 1.6 % Excess tax benefits from stock-based compensation 0.0 % 0.0 % -0.4 % -2.1 % Other 0.0 % 0.1 % 0.1 % 0.1 % Effective income tax rate 26.0 % 26.6 % 30.2 % 23.4 % State and local income taxes For the three months ended September 30, 2024, the impact of state and local income taxes on our effective income tax rate decreased from the same period in 2023, primarily due to the settlement of an uncertain tax position during the third quarter of 2024. For the nine months ended September 30, 2024, the impact of state and local income taxes on our effective income tax rate increased from the same period in 2023, primarily due to: • An adjustment to an uncertain tax position estimate during the second quarter of 2024, which increased our effective income tax rate by 230 basis points for the nine months ended September 30, 2024. • Changes in state tax laws that were enacted during the second quarter of 2024, which are expected to increase our long-term effective tax rate by approximately 10 basis points. The enactment of these tax law changes increased our effective income tax rate by 70 basis points for the nine months ended September 30, 2024. Non-deductible executive compensation expense We recognize non-deductible executive compensation expense as an increase of provision for income taxes or a reduction of benefit for income taxes. For the nine months ended September 30, 2024, the impact of non-deductible executive compensation expense on our effective income tax rate increased from the same period in 2023, primarily due to a decrease in pre-tax income. Excess tax benefits from stock-based compensation We recognize an excess tax benefit or tax deficiency when the deduction for the stock-based compensation expense of a stock award for tax purposes differs from the cumulative stock-based compensation expense recognized in the financial statements. The excess tax benefit or tax deficiency is recognized in provision for income taxes in the period in which the amount of the deduction is determined, which is when restricted stock units are settled in common stock or stock options are exercised. Excess tax benefits reduce our effective income tax rate, while tax deficiencies increase our effective income tax rate. The decrease in the impact of excess tax benefits on our effective income tax rate for the nine months ended September 30, 2024 was primarily due to a decrease in the number of restricted stock units that were settled in common stock during the first quarter of 2024 as compared to the first quarter of 2023 due to the timing of long-term stock award grants, partially offset by a decrease in pre-tax income.

Litigation and Contingent Liabilities	COMMITMENTS AND CONTINGENCIES Litigation and Other Legal Matters In the normal course of business and as a result of the consumer-oriented nature of the industry in which we operate, we and other industry participants are frequently subject to various consumer claims, litigation, and regulatory investigations seeking damages, fines, and statutory penalties. The claims allege, among other theories of liability, violations of state, federal, and foreign truth-in-lending, credit availability, credit reporting, consumer protection, warranty, debt collection, insurance, and other consumer-oriented laws and regulations, including claims seeking damages for alleged physical and mental harm relating to the repossession and sale of consumers’ vehicles and other debt collection activities. As the assignee of Consumer Loans originated by Dealers, we may also be named as a co-defendant in lawsuits filed by consumers principally against Dealers. We may also have disputes and litigation with Dealers. The claims may allege, among other theories of liability, that we breached the Dealer servicing agreement. We may also have disputes and litigation with vendors and other third parties. The claims may allege, among other theories of liability, that we breached a license agreement or contract. The damages, fines, and penalties that may be claimed by consumers, regulatory agencies, Dealers, vendors, or other third parties in these types of matters can be substantial. The relief requested by plaintiffs varies but may include requests for compensatory, statutory, and punitive damages and injunctive relief, and plaintiffs may seek treatment as purported class actions or they may file individual arbitration demands for which arbitration providers may request separate filing fees. The following matters include current actions to which we are a party and updates to matters that were disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023. On December 1, 2021, we received a subpoena from the Office of the Attorney General for the State of California seeking documents and information regarding GAP products, GAP product administration, and refunds. We are cooperating with this inquiry and cannot predict the eventual scope, duration, or outcome at this time. As a result, we are unable to estimate the reasonably possible loss or range of reasonably possible loss arising from this investigation. On May 7, 2019, we received a subpoena from the Consumer Frauds and Protection Bureau of the Office of the New York State Attorney General, relating to the Company’s origination and collection policies and procedures in the state of New York. After May 7, 2019 through April 30, 2021, we received additional subpoenas from the Office of the New York State Attorney General relating to the Company’s origination, collection, and securitization practices. On November 19, 2020 and August 23, 2022, we received letters from the Office of the New York State Attorney General indicating that it may commence litigation against the Company asserting violations of New York Executive Law § 63(12) and New York General Business Law §§ 349 and 352 et seq. and applicable federal laws, including but not limited to claims that the Company engaged in unfair and deceptive trade practices in auto lending, debt collection, and asset-backed securitizations in the State of New York in violation of the Dodd-Frank Wall Street Reform and Consumer Protection Act, New York Executive Law § 63(12), the New York Martin Act, and New York General Business Law § 349. See the description below of the lawsuit commenced by the Office of the New York State Attorney General on January 4, 2023. On April 22, 2019, we received a civil investigative demand from the Consumer Financial Protection Bureau (“Bureau”) seeking, among other things, certain information relating to the Company’s origination and collection of Consumer Loans, TPPs, and credit reporting. After April 22, 2019 through March 7, 2022, we received additional subpoenas from the Bureau. On December 6, 2021, we received a Notice and Opportunity to Respond and Advise letter from the Staff of the Office of Enforcement (“Staff”) of the Bureau, stating that the Staff was considering whether to recommend that the Bureau take legal action against the Company for alleged violations of the Consumer Financial Protection Act of 2010 (the “CFPA”) in connection with the Company’s consumer loan origination practices. See the description below of the lawsuit commenced by the Bureau on January 4, 2023. On January 4, 2023, the Office of the New York State Attorney General and the Bureau jointly filed a complaint in the United States District Court for the Southern District of New York alleging that the Company engaged in deceptive practices, fraud, illegality, and securities fraud in violation of New York Executive Law § 63(12) and New York General Business Law §§ 349 and 352, and that the Company engaged in deceptive and abusive acts and provided substantial assistance to a covered person or service provider in violation of the CFPA, 12 U.S.C. § 5531 and 12 U.S.C. § 5536(a)(1)(B). The complaint seeks injunctive relief, an accounting of all consumers for whom the Company provided financing, restitution, damages, disgorgement, civil penalties, and payment of costs. On March 14, 2023, the Company filed a motion to dismiss the complaint. On August 7, 2023, the court stayed the action pending the U.S. Supreme Court’s decision in Consumer Financial Protection Bureau v. Community Financial Services Association of America, Ltd. , No. 22-448 (“CFSA”). On July 1, 2024, the court lifted the stay in view of the decision in CFSA and requested revised briefing on the Company’s motion to dismiss that would address the intervening legal developments and sharpen the issues for resolution. As of October 29, 2024, the Company's motion to dismiss has been fully briefed. We are unable to estimate the reasonably possible loss or range of reasonably possible loss arising from this litigation. The Company intends to vigorously defend itself in this matter. On March 18, 2016, we received a subpoena from the Attorney General of the State of Maryland, relating to the Company’s repossession and sale policies and procedures in the state of Maryland. On April 3, 2020, we received a subpoena from the Attorney General of the State of Maryland relating to the Company’s origination and collection policies and procedures in the state of Maryland. On August 11, 2020, we received a subpoena from the Attorney General of the State of Maryland restating most of the requests contained in the March 18, 2016 and April 3, 2020 subpoenas, making additional requests, and expanding the inquiry to include 41 other states (Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Michigan, Minnesota, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, and Wisconsin) and the District of Columbia. Also on August 11, 2020, we received from the Attorney General of the State of New Jersey a subpoena that is essentially identical to the August 11, 2020 Maryland subpoena, both as to substance and as to the jurisdictions identified. The Company has been informed that the State of Kansas, the State of Texas, and the State of Iowa have withdrawn from the multistate investigation. We are cooperating with these investigations and cannot predict their eventual scope, duration, or outcome at this time. As a result, we are unable to estimate the reasonably possible loss or range of reasonably possible loss arising from these investigations. On December 9, 2014, we received a civil investigative subpoena from the U.S. Department of Justice pursuant to the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 directing us to produce certain information relating to subprime automotive finance and related securitization activities. We have cooperated with the inquiry, but cannot predict the eventual scope, duration, or outcome at this time. As a result, we are unable to estimate the reasonably possible loss or range of reasonably possible loss arising from this investigation. An adverse ultimate disposition in any action to which we are a party or otherwise subject could have a material adverse impact on our financial position, liquidity, and results of operations.

Accounting Policies [Abstract]
Business Segment Information	Business Segment Information We currently operate in one reportable segment which represents our core business of offering innovative financing solutions that enable automobile dealers to sell vehicles to consumers regardless of their credit history. The consolidated financial statements reflect the financial results of our one reportable operating segment.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents	Cash and Cash Equivalents and Restricted Cash and Cash Equivalents Cash equivalents consist of readily marketable securities with original maturities at the date of acquisition of three months or less. As of September 30, 2024 and December 31, 2023, we had $158.6 million and $12.8 million, respectively, in cash and cash equivalents that were not insured by the Federal Deposit Insurance Corporation (“FDIC”). Restricted cash and cash equivalents consist of cash pledged as collateral for secured financings and cash held in a trust for future vehicle service contract claims. As of September 30, 2024 and December 31, 2023, we had $551.8 million and $453.7 million, respectively, in restricted cash and cash equivalents that were not insured by the FDIC. The following table provides a reconciliation of cash and cash equivalents and restricted cash and cash equivalents reported in our consolidated balance sheets to the total shown in our consolidated statements of cash flows: (In millions) As of September 30, 2024 December 31, 2023 September 30, 2023 December 31, 2022 Cash and cash equivalents $ 159.7 $ 13.2 $ 3.1 $ 7.7 Restricted cash and cash equivalents 556.6 457.7 435.1 410.0 Total cash and cash equivalents and restricted cash and cash equivalents $ 716.3 $ 470.9 $ 438.2 $ 417.7
Restricted Securities, Available-for-sale	Restricted Securities Available for Sale Restricted securities available for sale consist of amounts held in a trust for future vehicle service contract claims. We determine the appropriate classification of our investments in debt securities at the time of purchase and reevaluate such determinations at each balance sheet date. Debt securities for which we do not have the intent or ability to hold to maturity are classified as available for sale, and stated at fair value with unrealized gains and losses, net of income taxes included in the determination of comprehensive income and reported as a component of shareholders’ equity.
Loans Receivable and Allowance for Credit Losses	Loans Receivable and Allowance for Credit Losses Consumer Loan Assignment. For legal purposes, a Consumer Loan is considered to have been assigned to us after the following has occurred: • the consumer and Dealer have signed a Consumer Loan contract; and • we have received the executed Consumer Loan contract and supporting documentation in either physical or electronic form. For accounting and financial reporting purposes, a Consumer Loan is considered to have been assigned to us after the following has occurred: • the Consumer Loan has been legally assigned to us; and • we have made a funding decision and generally have provided funding to the Dealer in the form of either an advance under the Portfolio Program or one-time purchase payment under the Purchase Program. Portfolio Segments and Classes. Our Loan portfolio consists of two portfolio segments: Dealer Loans and Purchased Loans. Our determination is based on the following: • We have two financing programs: the Portfolio Program and the Purchase Program. We are considered to be a lender to Dealers for Consumer Loans assigned under the Portfolio Program and a purchaser of Consumer Loans assigned under the Purchase Program. • The Portfolio Program and the Purchase Program have different levels of risk in relation to credit losses. Under the Portfolio Program, the impact of negative variances in Consumer Loan performance is mitigated by Dealer Holdback and the cross-collateralization of Consumer Loan assignments. Under the Purchase Program, we are impacted by the full amount of negative variances in Consumer Loan performance. • Our business model is narrowly focused on Consumer Loan assignments from one industry with expected cash flows that are significantly lower than the contractual cash flows owed to us due to credit quality. We do not believe that it is meaningful to disaggregate our Loan portfolio beyond the Dealer Loans and Purchased Loans portfolio segments. Each portfolio segment consists of one class of Consumer Loan assignments, which is Consumer Loans originated by Dealers to finance purchases of vehicles and related ancillary products by consumers with impaired or limited credit histories. Our determination is based on the following: • All of the Consumer Loans assigned to us have similar risk characteristics in relation to the categorization of borrowers, type of financing receivable, industry sector, and type of collateral. • We only accept Consumer Loan assignments from Dealers located within the United States. Recognition and Measurement Policy. On January 1, 2020, we adopted Accounting Standards Update 2016-13, Measurement of Credit Losses on Financial Instruments, which is known as the current expected credit loss model, or CECL. Loans outstanding prior to the adoption date are no longer material to our consolidated financial statements. Consumer Loans assigned to us on or subsequent to January 1, 2020 are accounted for as originated financial assets (“Originated Method”). Under the Originated Method, at the time of assignment, we: • calculate the effective interest rate based on contractual future net cash flows; • record a Loan receivable equal to the advance paid to the Dealer under the Portfolio Program or purchase price paid to the Dealer under the Purchase Program; and • record an allowance for credit losses equal to the difference between the initial Loan receivable balance and the present value of expected future net cash flows discounted at the effective interest rate. The initial allowance for credit losses is recognized as provision for credit losses expense. The effective interest rate and initial allowance for credit losses are significantly higher for Consumer Loans assigned under the Purchase Program than for Consumer Loans assigned under the Portfolio Program, as contractual net cash flows exceed expected net cash flows by a significantly greater margin under the Purchase Program. Under the Purchase Program, we retain all contractual collections that exceed our initial expectations. Under the Portfolio Program, contractual collections that exceed our initial expectations are substantially offset by additional Dealer Holdback payments. Under the Originated Method, for each reporting period subsequent to assignment, we: • recognize finance charge revenue using the effective interest rate that was calculated at the time of assignment based on contractual future net cash flows; and • adjust the allowance for credit losses so that the net carrying amount of each Loan equals the present value of expected future net cash flows discounted at the effective interest rate. The adjustment to the allowance for credit losses is recognized as either provision for credit losses expense or a reversal of provision for credit losses expense. Loans Receivable . Amounts advanced to Dealers for Consumer Loans assigned under the Portfolio Program are recorded as Dealer Loans and are aggregated by Dealer for purposes of recognizing revenue and measuring credit losses. Amounts paid to Dealers for Consumer Loans assigned under the Purchase Program are recorded as Purchased Loans and, for purposes of recognizing revenue and measuring credit losses, are not aggregated. The outstanding balance of each Loan included in Loans receivable is comprised of the following: • cash paid to the Dealer (or to third-party ancillary product providers on the Dealer’s behalf) for the Consumer Loan assignment (advance under the Portfolio Program or one-time purchase payment under the Purchase Program); • finance charges; • Dealer Holdback payments; • accelerated Dealer Holdback payments; • recoveries; • transfers in; • less: collections (net of certain collection costs); • less: write-offs; and • less: transfers out. Under our Portfolio Program, certain events may result in Dealers forfeiting their rights to Dealer Holdback. We transfer the Dealer’s outstanding Dealer Loan balance and the related allowance for credit losses balance to Purchased Loans in the period this forfeiture occurs. We aggregate these Purchased Loans by Dealer for purposes of recognizing revenue and measuring credit losses. Allowance for Credit Losses. The outstanding balance of the allowance for credit losses of each Loan represents the amount required to reduce net carrying amount of Loans (Loans receivable less allowance for credit losses) to the present value of expected future net cash flows discounted at the effective interest rate. Expected future net cash flows for Dealer Loans are comprised of expected future collections on the assigned Consumer Loans, less any expected future Dealer Holdback payments. Expected future net cash flows for Purchased Loans are comprised of expected future collections on the assigned Consumer Loans. Expected future collections are forecasted for each individual Consumer Loan based on the historical performance of Consumer Loans with similar characteristics, adjusted for recent trends in payment patterns. Our forecast of expected future collections includes estimates for prepayments and post-contractual-term cash flows. Unless the consumer is no longer contractually obligated to pay us, we forecast future collections on each Consumer Loan for a 120 month period after the origination date. Expected future Dealer Holdback payments are forecasted for each individual Dealer based on the expected future collections and current advance balance of each Dealer Loan. We fully write off the outstanding balances of a Loan and the related allowance for credit losses once we are no longer forecasting any expected future net cash flows on the Loan. Under our partial write-off policy, we write off the amount of the outstanding balances of a Loan and the related allowance for credit losses, if any, that exceeds 200% of the present value of expected future net cash flows on the Loan, as we deem this amount to be uncollectable. Credit Quality. The vast majority of the Consumer Loans assigned to us are made to individuals with impaired or limited credit histories. Consumer Loans made to these individuals generally entail a higher risk of delinquency, default, and repossession and higher losses than loans made to consumers with better credit. Since most of our revenue and cash flows are generated from these Consumer Loans, our ability to accurately forecast Consumer Loan performance is critical to our business and financial results. At the time a Consumer Loan is submitted to us for assignment, we forecast future expected cash flows from the Consumer Loan. Based on these forecasts, an advance or one-time purchase payment is made to the related Dealer at a price designed to maximize our economic profit, a non-GAAP financial measure that considers our return on capital, our cost of capital, and the amount of capital invested. We monitor and evaluate the credit quality of Consumer Loans on a monthly basis by comparing our current forecasted collection rates to our initial expectations. We use a statistical model that considers a number of credit quality indicators to estimate the expected collection rate for each Consumer Loan at the time of assignment. The credit quality indicators considered in our model include attributes contained in the consumer’s credit bureau report, data contained in the consumer’s credit application, the structure of the proposed transaction, vehicle information and other factors. We continue to evaluate the expected collection rate for each Consumer Loan subsequent to assignment primarily through the monitoring of consumer payment behavior. Our evaluation becomes more accurate as the Consumer Loans age, as we use actual performance data in our forecast. Since all known, significant credit quality indicators have already been factored into our forecasts and pricing, we are not able to use any specific credit quality indicators to predict or explain variances in actual performance from our initial expectations. Any variances in performance from our initial expectations are a result of Consumer Loans performing differently from historical Consumer Loans with similar characteristics. We periodically adjust our statistical pricing model for new trends that we identify through our evaluation of these forecasted collection rate variances. When overall forecasted collection rates underperform our initial expectations, the decline in forecasted collections has a more adverse impact on the profitability of the Purchased Loans than on the profitability of the Dealer Loans. For Purchased Loans, the decline in forecasted collections is absorbed entirely by us. For Dealer Loans, the decline in the forecasted collections is substantially offset by a decline in forecasted payments of Dealer Holdback. Methodolo gy Changes . During the second quarter of 2024, we applied an adjustment to our methodology for forecasting the amount of future net cash flows from our Loan portfolio, which reduced the forecasted collection rates for Consumer Loans assigned in 2022 through 2024. During the second quarter of 2023, we adjusted our methodology for forecasting the amount and timing of future net cash flows from our Loan portfolio through the utilization of more recent Consumer Loan performance and Consumer Loan prepayment data. For additional information, see Note 6. For the three and nine months ended September 30, 2024 and 2023, we did not make any other methodology changes for Loans that had a material impact on our financial statements.
Finance Charges	Finance Charges Sources of Revenue. Finance charges is comprised of: (1) interest income earned on Loans; (2) administrative fees earned from ancillary products; (3) program fees charged to Dealers under the Portfolio Program; (4) Consumer Loan assignment fees charged to Dealers; and (5) direct origination costs incurred on Dealer Loans. We provide Dealers the ability to offer vehicle service contracts to consumers through our relationships with Third-Party Providers (“TPPs”). A vehicle service contract provides the consumer protection by paying for the repair or replacement of certain components of the vehicle in the event of a mechanical failure. The retail price of the vehicle service contract is included in the principal balance of the Consumer Loan. The wholesale cost of the vehicle service contract is paid to the TPP, net of an administrative fee retained by us. The difference between the wholesale cost and the retail price to the consumer is paid to the Dealer as a commission. Under the Portfolio Program, the wholesale cost of the vehicle service contract and the commission paid to the Dealer are charged to the Dealer’s advance balance. TPPs process claims on vehicle service contracts that are underwritten by third-party insurers. We bear the risk of loss for claims on certain vehicle service contracts that are reinsured by us. We market the vehicle service contracts directly to Dealers. We provide Dealers the ability to offer Guaranteed Asset Protection (“GAP”) to consumers through our relationships with TPPs. GAP provides the consumer protection by paying the difference between the loan balance and the amount covered by the consumer’s insurance policy in the event of a total loss of the vehicle due to severe damage or theft. The retail price of GAP is included in the principal balance of the Consumer Loan. The wholesale cost of GAP is paid to the TPP, net of an administrative fee retained by us. The difference between the wholesale cost and the retail price to the consumer is paid to the Dealer as a commission. Under the Portfolio Program, the wholesale cost of GAP and the commission paid to the Dealer are charged to the Dealer’s advance balance. TPPs process claims on GAP contracts that are underwritten by third-party insurers. Program fees represent monthly fees charged to Dealers for access to our Credit Approval Processing System (“CAPS”); administration, servicing, and collection services offered by us; documentation related to or affecting our program; and all tangible and intangible property owned by Credit Acceptance. We charge a monthly fee of $599 to Dealers participating in our Portfolio Program and we collect it from future Dealer Holdback payments. Recognition Policy. We recognize finance charges under the interest method such that revenue is recognized on a level-yield basis over the life of the Loan. We calculate finance charges on a monthly basis by applying the effective interest rate of the Loan to the net carrying amount of the Loan (Loan receivable less the related allowance for credit losses). The effective interest rate is based on contractual future net cash flows. We report the change in the present value of credit losses attributable to the passage of time as a reduction to finance charges. Accordingly, we allocate finance charges recognized on each Loan between the Loan receivable and the related allowance for credit losses. The amount of finance charges allocated to the Loan receivable is equal to the effective interest rate applied to the Loans receivable balance. The reduction of finance charges allocated to the allowance for credit losses is equal to the effective interest rate applied to the allowance for credit losses balance.
Reinsurance	Reinsurance Our wholly owned subsidiary VSC Re Company (“VSC Re”) is engaged in the business of reinsuring coverage under vehicle service contracts sold to consumers by Dealers on vehicles financed by us. VSC Re currently reinsures vehicle service contracts that are offered through one of our TPPs. Vehicle service contract premiums, which represent the selling price of the vehicle service contract to the consumer, less fees and certain administrative costs, are contributed to a trust account controlled by VSC Re. These premiums are used to fund claims covered under the vehicle service contracts. VSC Re is a bankruptcy remote entity. As such, our exposure to fund claims is limited to the trust assets controlled by VSC Re and our net investment in VSC Re. Premiums from the reinsurance of vehicle service contracts are recognized over the life of the policy in proportion to expected costs of servicing those contracts. Expected costs are determined based on our historical claims experience. Claims are expensed through a provision for claims in the period the claim was incurred. Capitalized acquisition costs are comprised of premium taxes and are amortized as general and administrative expense over the life of the contracts in proportion to premiums earned. We have consolidated the trust within our financial statements based on our determination of the following: • We have a variable interest in the trust. We have a residual interest in the assets of the trust, which is variable in nature, given that it increases or decreases based upon the actual loss experience of the related service contracts. In addition, VSC Re is required to absorb any losses in excess of the trust’s assets. • The trust is a variable interest entity. The trust has insufficient equity at risk as no parties to the trust were required to contribute assets that provide them with any ownership interest. • We are the primary beneficiary of the trust. We control the amount of premiums written and placed in the trust through Consumer Loan assignments under our Programs, which is the activity that most significantly impacts the economic performance of the trust. We have the right to receive benefits from the trust that could potentially be significant. In addition, VSC Re has the obligation to absorb losses of the trust that could potentially be significant.
New Accounting Updates	New Accounting Updates Not Yet Adopted Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the “Codification”). The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If, by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. We are currently evaluating the impact the adoption of ASU 2023-06 will have on our consolidated financial statements and related disclosures. Improvements to Reportable Segment Disclosures. In November 2023, the FASB issued ASU 2023-07, which enhances the required disclosures for operating segments in our annual and interim consolidated financial statements. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted but we have not yet adopted ASU 2023-07. We are currently evaluating the impact the adoption of ASU 2023-07 will have on our consolidated financial statements and related disclosures. Improvements to Income Tax Disclosures. In December 2023, the FASB issued ASU 2023-09, which intends to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments intended to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted, but we have not yet adopted ASU 2023-09. We are currently evaluating the impact the adoption of ASU 2023-09 will have on our consolidated financial statements and related disclosures.

Consumer Loans assigned in 2022 had continued to underperform our expectations for several quarters. More recently, Consumer Loans assigned in 2023 had also begun exhibiting similar trends of underperformance, although not as severe as Consumer Loans assigned in 2022. During the second quarter of 2024, we determined that we had sufficient Consumer Loan performance experience to estimate the magnitude by which we expected Consumer Loans assigned in 2022 through 2024 would likely underperform our historical collection rates on Consumer Loans with similar characteristics. Accordingly, we applied an adjustment to Consumer Loans assigned in 2022 through 2024 to reduce forecasted collection rates to what we believed the ultimate collection rates would be based on these trends. Changes in the amount and timing of forecasted net cash flows are recognized in the period of change as a provision for credit losses. The implementation of this forecast adjustment during the second quarter of 2024 reduced forecasted net cash flows by $147.2 million, or 1.4%, and increased provision for credit losses by $127.5 million. During the second quarter of 2023, we adjusted our methodology for forecasting the amount and timing of future net cash flows from our Loan portfolio through the utilization of more recent Consumer Loan performance and Consumer Loan prepayment data. We had experienced a decrease in Consumer Loan prepayments to below-average levels and as a result, slowed our forecasted net cash flow timing. Historically, Consumer Loan prepayments have been lower in periods with less availability of consumer credit. Changes in the amount and timing of forecasted net cash flows are recognized in the period of change as a provision for credit losses. The implementation of the adjustment to our forecasting methodology during the second quarter of 2023 reduced forecasted net cash flows by $44.5 million, or 0.5%, and increased provision for credit losses by $71.3 million.

[1] Represents the total forecasted collections we expect to collect on the Consumer Loans as a percentage of the repayments that we were contractually owed on the Consumer Loans at the time of assignment. Contractual repayments include both principal and interest. Forecasted collection rates are negatively impacted by canceled Consumer Loans as the contractual amount owed is not removed from the denominator for purposes of computing forecasted collection rates in the table. The forecasted collection rates presented for Dealer Loans and Purchased Loans reflect the Consumer Loan classification at the time of assignment.

[1] As Consumer Loans are aggregated by Dealer for purposes of recognizing revenue and measuring credit losses, the Dealer Loan amount was estimated by allocating the balance of each Dealer Loan to the underlying Consumer Loans based on the forecasted future collections of each Consumer Loan. As certain Consumer Loans are aggregated by Dealer or month of purchase for purposes of recognizing revenue and measuring credit losses, the Purchased Loan amount was estimated by allocating the balance of certain Purchased Loans to the underlying Consumer Loans based on the forecasted future collections of each Consumer Loan. Represents the Loan balance attributable to Consumer Loans outstanding within their initial loan terms. We consider a Consumer Loan to be current for purposes of forecasting expected collection rates if contractual repayments are less than 11 days past due. Represents the Loan balance attributable to Consumer Loans outstanding beyond their initial loan terms.
