This investigation was part of an ongoing industry-wide investigation by the states and the federal government of commercial practices. The comprehensive settlements with federal and state agencies will conclude all liabilities to the government in connection with the investigation. In April 2005, the company announced that it had taken a $725 million provision to cover the settlement and related costs. The provision, which was recorded as an exceptional charge in the company's earnings report for the first quarter of 2005, will be sufficient to cover the comprehensive settlements and related costs. The comprehensive settlements also include a Corporate Integrity Agreement, administered through the Office of the Inspector General. "This settlement concludes a four-year government investigation into commercial practices related to Serostim, and we are pleased to put the matter behind us," said Thomas G. Gunning, Vice President and General Counsel, Serono U.S. "The activities described in the settlement were confined to one unit in our U.S. operations and cover a brief period in our history. Serono takes compliance issues very seriously and has a rigorous compliance program to ensure that its employees meet the highest ethical standards. We now look forward to continuing to focus and devote our energies on our core mission of developing treatments to meet unmet medical needs." ### ABOUT SERONO Serono is a global biotechnology leader.
