These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date and the amounts of revenues and expenses recognized during the reporting period. Management analyzes the Company’s estimates based on historical experience and other assumptions that are believed to be reasonable under the circumstances, however, actual results could differ materially from such estimates. The significant estimates made by management in the accompanying Consolidated Financial Statements include, but are not limited to, inventory valuation adjustments, reserves for future chargebacks on finance, insurance and VSC fees, self-insured property and casualty insurance exposure, the fair value of assets acquired and liabilities assumed in business combinations, the valuation of goodwill and intangible franchise rights, and reserves for potential litigation.
