Restructuring | 14. Restructuring In the fourth quarter of fiscal 2016, the Board of Directors approved a plan of restructuring intended to streamline and flatten the Company’s organization, reduce overall headcount by approximately 30%, and reduce its overall cost structure by approximately $2.5 million per quarter. The restructuring plan resulted in special charges totaling $0.3 million recorded during the three month period ended December 31, 2016. These charges were for primarily related to severance costs and were all paid out by December 31, 2016. In the first quarter of fiscal 2017, the Board of Directors approved an additional restructuring plan intended to further streamline and flatten the Company’s organization, reduce overall headcount by approximately 16%, and reduce its overall cost structure by another $0.9 - $1.0 million per quarter. The restructuring plan will result in special charges totaling approximately $0.3 million to be recorded during the three-month period ending March 31, 2017. These charges are primarily related to severance costs and include $0.1 million of non-cash stock-based compensation severance.
