Accounting Policies [Abstract] |
Unusual Risks and Uncertainties | Recent Accounting Pronouncements – Please refer to Note 1, “Description of Business and Summary of Significant Accounting Policies,” to the consolidated financial statements in Sonic’s Annual Report on Form 10-K for the year ended December 31, 2022 for further discussion of recent accounting pronouncements. Change in Accounting Principle – During the first quarter of 2023, Sonic voluntarily changed the date of its annual goodwill impairment test and other intangible assets impairment test from October 1 to April 30. This change is preferable under the circumstances as it provides Sonic with better alignment of the annual impairment test with the availability of final approved prospective financial information for use in projecting future cash flows in our impairment models. We intend to utilize the same valuation approach and do not expect the change in valuation date to produce different impairment results. This change is not applied retrospectively as it is impracticable to do so because retrospective application would require the application of significant estimates and assumptions with the use of hindsight. Accordingly, the change was applied prospectively, beginning with the April 30, 2023 impairment test date.
