2016 Restructuring

We anticipate completing the 2016 restructuring program during the second quarter of 2016. During the three months ended April 1, 2016, the Company incurred restructuring costs of $2.5 million related to the 2016 restructuring plan.

2011 Restructuring

In November 2011, the Company announced a strategic initiative (“2011 restructuring”), which aimed to consolidate operations to reduce the Company’s cost structure and improve operational efficiency. As part of this initiative, the Company eliminated facilities through the consolidation of certain manufacturing, sales and distribution facilities and the exit of Semiconductor and Laser Systems businesses. The Company substantially completed the 2011 restructuring program by the end of 2013. In March 2016, the Company sold our previously exited Laser Systems facility located in Orlando, Florida for a net cash consideration of $3.6 million. Restructuring costs for the three months ended April 1, 2016 included facility costs of $0.2 million related to the Orlando, Florida facility. These costs were recorded in the Unallocated Corporate and Shared Services reportable segment.
