3. CESSATION OF SFAS NO. 142 AMORTIZATION
Effective January 1, 2002, we adopted SFAS No. 142. It requires that goodwill and certain intangible assets will no longer be subject to amortization, but instead will be subject to a periodic impairment assessment by applying a fair value based test based upon a two-step method. The first step is to identify potential goodwill impairment by comparing the estimated fair value of the reporting units to their carrying amounts. The second step measures the amount of the impairment based upon a comparison of implied fair value of goodwill with its carrying value. The balance of goodwill was $192.1 million and $123.1 million as December 31, 2004 and 2003, respectively.
