[1] 2010 vs. 2009 - The decrease in the domestic loss was due to revenues from legacy Wyeth products and a reduction in domestic restructuring charges partially offset by increased amortization charges primarily related to identifiable intangibles in connection with our acquisition of Wyeth and litigation charges primarily related to our wholly owned subsidiary Quigley Company, Inc. The decrease in international income was due primarily to an increase in international restructuring and amortization charges plus the non-recurrence of the gain in 2009 in connection with the formation of ViiV, partially offset by revenues from legacy Wyeth products.
[2] Income from continuing operations before provision for taxes on income.
[3] For 2011, includes King commencing on the acquisition date of January 31, 2011. For 2009, includes Wyeth commencing on the acquisition date of October 15, 2009.
[4] 2011 vs. 2010 - The decrease in the domestic loss was primarily due to the non-recurrence of a charge of $1.3 billion (pre-tax) in 2010 for asbestos litigation related to our wholly owned subsidiary, Quigley Company, Inc., partially offset by a reduction in revenues due to the loss of exclusivity for several biopharmaceutical products and the impact of the U.S. Healthcare Legislation. The increase in international income was due to the favorable impact of foreign exchange, higher impairment charges in 2010, as well as increased revenues from the biopharmaceutical products such as the Prevnar/Prevenar franchise, Enbrel and Celebrex.
