Contingent Liabilities	Contingent Liabilities Litigation. On October 31, 2017, Joshua Sabanovich v. CarMax Superstores California, LLC et al., a putative class action, was filed in the Superior Court of California, County of Stanislaus asserting wage and hour claims with respect to CarMax sales consultants and non-exempt employees in California. The asserted claims include failure to pay minimum wage; provide meal periods and rest breaks; pay statutory/contractual wages; reimburse for work-related expenses and provide accurate itemized wage statements; unfair competition; and Private Attorneys General Act (“PAGA”) claims. The Sabanovich lawsuit seeks unspecified damages, restitution, statutory penalties, interest, cost and attorneys’ fees. Based upon our evaluation of information currently available, we believe that the ultimate resolution of the Sabanovich lawsuit will not have a material adverse effect on our financial condition, results of operations or cash flows. CarMax entities are defendants in three proceedings asserting wage and hour claims with respect to non-exempt CarMax employees in California. The asserted claims include failure to provide meal periods and rest breaks; pay statutory or contractual wages; reimburse for work-related expenses; and PAGA claims. Two of these claims have been filed in court, whereas one has yet to be filed in court. On July 9, 2021, Daniel Bendure v. CarMax Auto Superstores California, LLC et al., a putative class action, was filed in the Superior Court of California, County of San Bernardino. The Bendure lawsuit seeks civil penalties for violation of the Labor Code, attorneys’ fees, costs, restitution of unpaid wages, interest, injunctive and equitable relief, general damages, and special damages. On August 12, 2021, Jordon Miller v. CarMax Auto Superstores California, LLC et al., a putative class action, was filed in the Superior Court of California, County of Riverside. The Miller lawsuit also seeks civil penalties for violation of the Labor Code, attorneys’ fees, costs, restitution of unpaid wages, interest, injunctive and equitable relief, general damages, and special damages. On August 3, 2021, Charles Walker filed a notice with the California Labor Workforce Development Agency, which is a prerequisite to filing a PAGA action in court. To date, Walker has not yet filed a lawsuit. We are unable to make a reasonable estimate of the amount or range of loss that could result from an unfavorable outcome in these matters. The company was a class member in a consolidated and settled class action lawsuit (In re: Takata Airbag Product Liability Litigation (U.S. District Court, Southern District of Florida)) against Toyota, Mazda, Subaru, BMW, Honda, Nissan and Ford related to the economic loss associated with defective Takata airbags installed as original equipment in certain model vehicles from model years 2000-2018. On April 15, 2020, CarMax received $40.3 million in net recoveries from the Toyota, Mazda, Subaru, BMW, Honda and Nissan settlement funds. CarMax remains a class member for the Ford settlement fund. We are unable to make a reasonable estimate of the amount or range of gain that could result from CarMax’s participation in the Ford settlement fund. The company is a class member in a consolidated and settled class action lawsuit (In re: General Motors Ignition Switch Litigation (U.S. District Court, Southern District of New York)) against General Motors related to the economic loss associated with certain model vehicles previously subject to recall for ignition switches, electronic power steering, and side impact airbags, for model years 1997-2014. On November 30, 2021, CarMax received $22.6 million in net recoveries from the GM settlement fund. We are involved in various other legal proceedings in the normal course of business. Based upon our evaluation of information currently available, we believe that the ultimate resolution of any such proceedings will not have a material adverse effect, either individually or in the aggregate, on our financial condition, results of operations or cash flows. Other Matters. In accordance with the terms of real estate lease agreements, we generally agree to indemnify the lessor from certain liabilities arising as a result of the use of the leased premises, including environmental liabilities and repairs to leased property upon termination of the lease. Additionally, in accordance with the terms of agreements entered into for the sale of properties, we generally agree to indemnify the buyer from certain liabilities and costs arising subsequent to the date of the sale, including environmental liabilities and liabilities resulting from the breach of representations or warranties made in accordance with the agreements. We do not have any known material environmental commitments, contingencies or other indemnification issues arising from these arrangements. As part of our customer service strategy, we guarantee the used vehicles we retail with a 90-day/4,000 mile limited warranty. A vehicle in need of repair within this period will be repaired free of charge. As a result, each vehicle sold has an implied liability associated with it. Accordingly, based on historical trends, we record a provision for estimated future repairs during the guarantee period for each vehicle sold. The liability for this guarantee was $19.3 million as of November 30, 2021, and $15.2 million as of February 28, 2021, and is included in accrued expenses and other current liabilities.
