Restructuring [Abstract]
Restructuring	3. Restructuring During the second half of 2011, the company initiated certain restructuring actions in order to improve its overall cost structure and enhance operational effectiveness. These actions included the realignment of certain sales functions in the United States. In connection with these actions, the company recorded employee separation costs under the company's existing severance programs of $12.0 million ($8.1 million after tax). Substantially all of these costs are expected to be cash expenditures. At December 31, 2011, the remaining liability related to this restructuring charge was $7.4 million, which reflects cash payments of $3.0 million and a reversal of $1.6 million of these costs. The company expects activities under these actions to be substantially complete by the end of 2012. In December 2010, the company committed to a plan (the "2010 Restructuring Plan") to improve its overall cost structure and enhance operational effectiveness. The 2010 Restructuring Plan included the realignment of certain manufacturing, sales and marketing, and administrative functions. In connection with this plan, the company recorded employee separation costs under the company's existing severance programs and other costs related to one-time employee termination benefits of $16.7 million ($11.4 million after tax). Substantially all of these costs were cash expenditures paid during 2011. In addition, $2.6 million of these restructuring costs were reversed in 2011. In April 2009, the company announced a plan (the "2009 Restructuring Plan") to reduce its overall cost structure and improve efficiency. The 2009 Restructuring Plan included the consolidation of certain businesses in the United States and the realignment of certain sales and marketing functions outside the United States. The 2009 Restructuring Plan resulted in the elimination of certain positions and other employee terminations worldwide. The company recorded employee separation costs under the company's existing severance programs and other costs primarily related to one-time termination benefits offered under this plan. The total cost of the 2009 Restructuring Plan was $15.4 million ($10.2 million after tax). Substantially all of these costs were cash expenditures and were paid during 2010.
