Restructuring and Other

During the six months ended June 30, 2018 and 2017, we continued to analyze our cost structure and re-align our cost structure following our business acquisitions. These charges primarily relate to integrating recently acquired businesses, consolidating facilities, eliminating redundancies, and lowering our operating expense run rate. Restructuring and other consists primarily of restructuring, severance, short-term retention costs, facility downsizing and relocation, and acquisition integration expenses.

Restructuring and other costs were $3.0 and $7.7 million during the three and six months ended June 30, 2018, respectively, and were $3.7 and $4.6 million during the three and six months ended June 30, 2017, respectively. Restructuring and other costs include severance charges of $1.3 and $4.4 million related to reductions in head count of 28 and 83 during the three and six months ended June 30, 2018, respectively; and $3.1 and $3.5 million related to reductions in head count of 95 and 113 during the three and six months ended June 30, 2017, respectively. Severance costs include severance payments, related employee benefits, outplacement fees, recruiting, and employee relocation costs.

Facilities relocation and downsizing expenses were $0.5 and $1.0 million during the three and six months ended June 30, 2018, respectively; and were $0.2 and $0.2 million during the three and six months ended June 30, 2017, respectively. These expenses were primarily related to the relocation of certain manufacturing and administrative locations due to reduced space requirements. Integration expenses of $1.1 and $2.3 million during the three and six months ended June 30, 2018, respectively, and $0.4 and $0.8 million during the three and six months ended June 30, 2017, respectively, were incurred for the integration of our business acquisitions.
