We use estimates, assumptions, and judgments when assessing the recoverability of goodwill and acquisition-related intangible assets. We test for impairment on an annual basis, or more frequently if a significant event or circumstance indicates the carrying amounts may not be recoverable. We also evaluate the estimated remaining useful lives of acquisition-related intangible assets for changes in circumstances that warrant a revision to the remaining periods of amortization. If the useful life of the intangible asset is shorter than originally estimated, we accelerate the rate of amortization and amortize the remaining carrying value over the new shorter useful life.
