9. Restructuring

The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420, Exit or Disposal Cost Obligations (“ASC 420”) and ASC Topic 712, Compensation—Nonretirement Postemployment Benefits (“ASC 712”). In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet.

During the years ended March 31, 2015 and 2014, the Company undertook restructuring activities, approved by the Board of Directors, in order to reorganize its global operations, streamline various functions of the business, and reduce its global workforce to better reflect the demand for its products. During the year ended March 31, 2014, the Company undertook a plan to consolidate its Grid manufacturing activities into its Devens, Massachusetts facility and close its facility in Middleton, Wisconsin which was completed during the year ended March 31, 2015. In addition, the Company established a new Wind manufacturing facility in Romania and as a result, reduced the headcount in its operation in China. The Company is maintaining its headcount in China at a level necessary to support demand from its Chinese customers. The Company recorded restructuring charges for severance and other costs of approximately $0.5 million and $1.9 million during the three and nine months ended December 31, 2014, respectively, primarily associated with the consolidation of the Company’s Grid manufacturing activities in the United States. From April 1, 2011 through December 31, 2015, the Company’s various restructuring activities resulted in a substantial reduction of its global workforce. All amounts related to these restructuring activities have been paid as of December 31, 2015.
