Restructuring Costs

During the years ended December 31, 2018, 2017 and 2016, the Company recorded net pre-tax restructuring expenses totaling $8.2 million, $0.6 million and $1.4 million, respectively. In 2013, the Company initiated a realignment plan that included closing six not-to-scale sites in the United States and Europe and a transfer of those operations to the Company's larger facilities ("the 2013 Realignment Program"). The Company also consolidated its optics and laser manufacturing businesses to better realize the benefits of vertical integration in these areas. The 2013 Realignment Program was concluded in 2018. During the years ended December 31, 2018, 2017 and 2016, the Company also incurred other restructuring charges associated with cost reduction initiatives that were not related to the 2013 Realignment Program.
