The December 31, 2012 balance sheet information has been derived from the audited financial statements at that date but does not include all disclosures required by GAAP.     In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are normal and recurring, necessary for a fair presentation of the statement of results of operations, financial position, other comprehensive income and cash flows. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission (SEC) on February 26, 2013. Operating results for the three and six months ended June 30, 2013 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2013.     The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosures of contingent amounts in our consolidated financial statements and the accompanying notes. Actual results could differ from those estimates. </div> </div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for basis of accounting, or basis of presentation, used to prepare the financial statements (for example, US Generally Accepted Accounting Principles, Other Comprehensive Basis of Accounting, IFRS).No definition available.false0Basis Of PresentationfalseBusiness Description And Basis Of Presentation (Policy)UnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.dealertrack.com/2010-09-30/role/DisclosureBusinessDescriptionAndBasisOfPresentationPolicy12
