Restructuring Plan	Restructuring Plan In July 2018, we established a restructuring plan related to our operations in the Netherlands, which are part of our Solar operating segment (the “Plan”). The goal of the Plan is to reduce operating costs and better align our workforce with the current needs of our solar business and enhance our competitive position for long-term success. Once fully implemented, we expect the Plan to reduce operating costs by approximately $3.0 million on an annualized basis. Under the Plan, we will reduce our Solar workforce by approximately 35-40 employees (approximately 20%). The affected employees are covered by a collective bargaining agreement, which defines the amount due to employees in the event of involuntary termination. We recorded $0.9 million of one-time termination costs in the fourth quarter of fiscal 2018. It is expected that these efforts will be completed by the end of our third quarter of fiscal 2019.
