Restructuring

On an ongoing basis, the Company evaluates its business and objectives to ensure that it is properly configured and sized based on changing market conditions. Accordingly, the Company has initiated certain restructuring initiatives, including plant rationalizations and targeted workforce reduction efforts, as deemed appropriate.

In addition to previously initiated actions, in January 2015, the Company announced its intention to further restructure its European manufacturing footprint based on current and anticipated market demands. The total estimated cost of this initiative, which is expected to be completed in 2017, is approximately $125,000, of which approximately $69,000 has been incurred to date.

The Company previously implemented several other restructuring initiatives, including the closure or consolidation of facilities throughout the world and the reorganization of the Company's operating structure. While substantially complete, the Company continues to incur costs on some of these initiatives, primarily related to the disposal of the respective facilities.

The Company's restructuring charges consist of severance, retention and outplacement services, and severance-related postemployment benefits (collectively, “employee separation costs”), other related exit costs and asset impairments related to restructuring activities.
