Basis Of Presentation [Abstract]

Basis Of Presentation

1. Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles ("GAAP") and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements of Sonic Corp. (the "Company"). In the opinion of management, these financial statements reflect all adjustments of a normal recurring nature, including recurring accruals, necessary for the fair presentation of the Company's financial position, results of operations and cash flows for the interim periods presented in conformity with GAAP. In certain situations, recurring accruals, including franchise royalties, are based on more limited information at interim reporting dates than at the Company's fiscal year end due to the abbreviated reporting period. Actual results may differ from these estimates. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the fiscal year ended August 31, 2012 included in the Company's Annual Report on Form 10-K. Interim results are not necessarily indicative of the results that may be expected for a full year or any other interim period.

Principles of Consolidation

     The accompanying financial statements include the accounts of the Company, its wholly owned subsidiaries and a number of Company Drive-Ins in which a subsidiary has a controlling ownership interest. All intercompany accounts and transactions have been eliminated.

Reclassifications

     Certain amounts reported in previous years, which are not material, have been combined and reclassified to conform to the current year presentation.
