We substantially completed the 2016 restructuring program during the second quarter of 2016. As of June 30, 2017, the Company incurred cumulative costs related to this restructuring plan totaling $6.4 million.

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 Systems and Laser Systems businesses. The Company substantially completed the 2011 restructuring program by the end of 2013. In March 2016, the Company sold its previously exited Laser Systems 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.
