In Fiscal 2017, we incurred approximately $1.3 million of restructuring costs, as we continued to reduce our overall cost structure to better align our costs with future production requirements. In Fiscal 2016, we incurred approximately $7.9 million of separation costs, of which $3.8 million were separation costs related to the departure of our former Chief Executive Officer in December 2015. Additionally in Fiscal 2016, we incurred approximately $0.5 million of restructuring costs related to a Canadian facility that we leased and exited in the third quarter of Fiscal 2016.
