PacifiCare member data is being reviewed by UnitedHealth Group pursuant to the December 20, 2005 merger. As of December 31, 2005, PacifiCare estimated year-end commercial membership of approximately 2.3 million accessing risk-based benefits and 100,000 accessing fee-based benefits. In addition, approximately 750,000 individuals received Medicare-sponsored benefits as of December 31, 2005. The member data reflects projected fourth quarter net sales and dis-enrollment activities and a partial writedown related to the rapid run-off experienced by its 2005 Pacific Life indemnity insurance acquisition, representing a total net reduction of approximately 100,000 commercial members, as well as the discontinuance of approximately 70,000 members to be divested pursuant to a Consent Decree with the Department of Justice and the completed divestiture of PacifiCares Guam-based business. Beginning in the first quarter of 2006, membership for PacifiCare will be included in UnitedHealth Groups reported amounts.
