2. 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. At June 30, 2012, the remaining liability related to these restructuring actions was $1.4 million, which reflects cash payments made in 2012 of $4.4 million and a reversal of $1.6 million of restructuring costs. The company expects activities under these restructuring actions to be substantially complete by the end of 2012.
