[1] Restructuring:In fiscal year 2012, the Company announced a multi-year strategic cost reduction initiative (“structural cost improvement initiative”). This initiative impacts both segments as well as the Corporate Services Group. The goal of this initiative is to properly position the Company’s cost structure globally to perform in the current economic environment without adversely impacting its growth or innovation potential. Key components of the structural cost improvement initiative include:•the strategic alignment of manufacturing, sales and R&D facilities to cost-effectively deliver high-quality products and superior service to the Company’s customers worldwide,•creation of regional shared financial services centers for the handling of accounting transaction processing and other accounting functions,•reorganization of sales functions, to more cost-efficiently deliver superior service to the Company’s customers globally, and•reductions in headcount across all functional areas, enabled by efficiencies gained through the Company’s ERP systems, as well as in order to align to economic conditions.Restructuring charges recorded in fiscal year 2014 primarily reflect the expenses incurred in connection with the Company’s structural cost improvement initiative as discussed above. Restructuring charges in fiscal year 2014 also includes the impairment of assets of $4,002 related to the discontinuance of a specific manufacturing line due to excess capacity as a result of recent acquisitions.Restructuring charges recorded in fiscal year 2013 primarily reflect the expenses incurred in connection with the Company’s structural cost improvement initiative as discussed above.Restructuring charges recorded in fiscal year 2012 primarily reflect the expenses incurred in connection with the Company’s structural cost improvement initiative as discussed above. Restructuring charges in fiscal year 2012 also include asset impairment charges related to the above mentioned initiative, partly offset by a gain on the divestiture of a non-strategic asset group.
