Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill | We test goodwill of our Domestic, Import, and Premium Luxury reporting units for impairment annually as of April 30 or more frequently when events or changes in circumstances indicate that the carrying value of a reporting unit more likely than not exceeds its fair value. Under accounting standards, an entity is permitted to first make a qualitative assessment of any potential goodwill impairment to determine whether it is necessary to calculate the fair value of a reporting unit under the quantitative two-step goodwill impairment test.
Intangible Assets, Indefinite-Lived | Our principal identifiable intangible assets are individual store rights under franchise agreements with vehicle manufacturers, which have indefinite lives and are tested at least annually as of April 30 for impairment. Under accounting standards, an entity is permitted to first make a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it is necessary to perform a quantitative impairment test.
