2016 Restructuring

During the third quarter of 2015, the Company initiated the 2016 restructuring program, which includes consolidating certain of our manufacturing operations to optimize our facility footprint and better utilize resources, and reducing redundant costs due to productivity cost savings and business volume reductions. Restructuring costs incurred in 2016 of $2.4 million, $(0.2) million and $0.8 million were related to severance, facility, and other, respectively. We substantially completed the 2016 restructuring program during the second quarter of 2016. In August 2016, the Company sold our facility in Chatsworth, California for a net cash consideration of $3.4 million and recognized a gain on sale of $1.6 million as part of restructuring, acquisition and divestiture related costs. As of December 31, 2016, the Company incurred cumulative costs related to this restructuring plan totaling $6.2 million, net of the gain on sale of the Chatsworth, California facility. The Company expects to incur additional restructuring charges of $0.2 million to $0.3 million related to the 2016 restructuring plan in the next twelve months.

2015 Restructuring

During the first quarter of 2015, the Company implemented a program to eliminate redundant costs, as a result of acquisition and divestiture activities, to better align our operations to our strategic growth plans, to further integrate our business lines, and as a consequence of our productivity initiatives.

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. In total, eleven facilities have been exited as part of the 2011 restructuring plan. These eliminations resulted in the consolidation of the manufacturing facilities of the Scientific Lasers business and the optics products, the consolidation of the Company’s German operations into one facility, the consolidation of the laser scanners business into the Company’s Bedford, Massachusetts facility and the consolidation of the Company’s Japan operation into one facility. Included in the eleven facilities exited are five facilities exited as part of the Semiconductor and Laser Systems business divestitures. The restructuring costs for the Semiconductor and Laser Systems businesses have been excluded from the table below as they have been reported as part of the operating results from discontinued operations. The Company substantially completed the 2011 restructuring program in 2013. In March 2016, the Company sold our previously exited facility located in Orlando, Florida for cash at the net carrying value of $3.5 million. In December 2016, the lease agreement for the Company’s previously exited laser scanner business facility was terminated, which resulted in a benefit of $0.2 million. Restructuring costs from the 2011 restructuring program recognized in 2016 are primarily depreciation and other costs related to the Orlando, Florida facility and the previously exited laser scanners business facility.
