Restructuring

During the three months ended March 31, 2015, we completed a restructuring initiative after the acquisition of DR Systems that reduced our workforce by approximately 6% due to the existence of redundant positions.  We recorded restructuring charges of $1,178 related to this initiative.  The following table sets forth the activity in the three months ended March 31, 2015, related to restructuring activities consisting solely of employee termination costs:
