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. Restructuring costs for the three and nine months ended October 2, 2015 included facility costs related to the Company’s vacant Orlando, Florida facility, which the Company owns and was previously occupied by the Laser Systems business. These costs were recorded in the Unallocated Corporate and Shared Services Costs segment.

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. During the nine months ended October 2, 2015, the Company incurred restructuring costs of $1.5 million related to the 2015 restructuring plan. Restructuring costs incurred during the nine months ended October 2, 2015 of $0.6 million, $0.5 million, $0.1 million and $0.3 million related to the Laser Products, Vision Technologies, Precision Motion and Unallocated Corporate and Shared Services Costs reportable segments, respectively.

2016 Restructuring

During the third quarter of 2015, the Company initiated a program targeting annualized savings of $4.5 million to $5.5 million after the program is fully executed. The 2016 restructuring program includes consolidating 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. We expect to incur cash charges of $3.5 million to $4.5 million related to this program, which we anticipate completing during the second quarter of 2016. During the three and nine months ended October 2, 2015, the Company incurred restructuring costs of $0.8 million related to the 2016 restructuring plan. Restructuring costs incurred during the three and nine months ended October 2, 2015 of $0.4 million, $0.1 million and $0.3 million related to the Vision Technologies, Precision Motion and Unallocated Corporate and Shared Services Costs reportable segments, respectively.
