Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation. The accompanying unaudited interim consolidated financial statements ("Consolidated Financial Statements") have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") and the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2023, which are included in the Company's Annual Report on Form 10-K as filed with the SEC on February 22, 2024 (the "December 31, 2023 Financial Statements"). The significant accounting policies used in preparing these Consolidated Financial Statements were applied on a basis consistent with those reflected in the December 31, 2023 Financial Statements. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, cash flows and changes in stockholders' equity as of the dates and for the periods indicated. The unaudited results of operations for the three months ended March 31, 2024 are not necessarily indicative of results that may be expected for the year ending December 31, 2024.
Use of Estimates | Use of Estimates. The preparation of the accompanying Consolidated Financial Statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates.
Reclassification | Reclassifications. Certain prior year balances have been reclassified to conform to the current year presentation.
Principles of Consolidation | Principles of Consolidation. The accompanying Consolidated Financial Statements include the accounts of Cars.com Inc. and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation.
