D. Impairment of Acquired Intangible Assets, Goodwill and Other Long-Lived Assets
SFAS No. 142, Goodwill and Other Intangible Assets, requires that goodwill be tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, sale or disposition of a significant portion of a reporting unit. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for a reporting unit.
