16. 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, 2014 and 2013, 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 in 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 to a level necessary to support demand from its Chinese customers. The Company also undertook a workforce reduction in July 2013, reducing its workforce by approximately 7%, impacting primarily selling, engineering and general and administrative functions. During the year ended March 31, 2013, the Company consolidated certain of its business operations to reduce overall facility costs. The Company recorded restructuring charges for severance and other costs of approximately $1.9 million, $1.7 million, and $2.5 million during the years ended March 31, 2015, 2014, and 2013 respectively. The restructuring charge for the fiscal year ended March 31, 2015 primarily represents severance, relocation and lease termination costs associated with closure of the Company’s Middleton, WI facility. From April 1, 2011 through March 31, 2015, the Company’s various restructuring activities resulted in a substantial reduction of its global workforce. Remaining unpaid amounts under these restructuring activities are expected to be paid by August 31, 2015.
