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, costs associated with discontinuing our radiology product line and reducing redundant costs due to productivity cost savings and business volume reductions. 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.
