Impairment of Long-Lived Assets

In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-lived Assets,” we evaluate long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss may be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposal are less than its carrying amount. In such instances, additional analysis is performed and the carrying value of long-lived assets is reduced to the estimated fair value, if this is lower, as determined using an appraisal or discounted cash flows, as appropriate.

In the second quarter of 2006, taking into account the planned divestiture of the Phase II-IV Clinical business, the Company performed an impairment test on the long-lived assets of the Clinical Phase II-IV business. Based on this analysis, the Company determined that the book value of assets assigned to the Clinical Phase II-IV business exceeded its future cash flows, which included the proceeds from the sale of the business, and therefore recorded an impairment of the assets of $3,900.
