10. 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 year ended March 31, 2012, the Company initiated restructuring activities 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. These activities resulted in the reduction of its global workforce by approximately 50%. During the six months ended September 30, 2012, the Company incurred restructuring costs of $0.1 million. These additional charges were paid as of September 30, 2012 and the remaining balance of accrued restructuring is expected to be paid through March 2013.
