Other Intangible Assets
Other intangible assets consist primarily of trademarks with indefinite lives which are tested for impairment annually or more frequently if indefinite useful lives are no longer appropriate. Definite-lived intangible assets, which mainly consist of contract-based patents and copyrights, are amortized over their estimated useful lives, and are tested for impairment when facts and circumstances indicate that the carrying values may not be recoverable. For further information on other intangible assets, see Note 9. Based on the impairment tests performed there was no impairment of other intangible assets in fiscal 2009, 2008 and 2007.
