Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING During fiscal years 2019, 2018 and 2017, the Company recorded restructuring expenses totaling approximately $50.7 million, $67.7 million, and $2.1 million, respectively, related to (1) fiscal 2019 actions to reduce operating expenses and improve manufacturing cost structure, (2) fiscal 2018 actions to improve operating efficiencies, and (3) actions resulting from the Business Combination. In the third quarter of fiscal 2019, the Company initiated restructuring actions to reduce operating expenses and improve its manufacturing cost structure, including the phased closure of a wafer fabrication facility in Florida and idling production at a wafer fabrication facility in Texas. As a result of these actions, the Company recorded approximately $7.7 million of expenses primarily related to employee termination benefits in "Other operating expense" in the Consolidated Statement of Operations. Additionally, the Company recorded accelerated depreciation of $21.3 million (to reflect changes in estimated useful lives of certain property and equipment, pursuant to ASC 360) and impairment charges of $15.9 million (to adjust the carrying value of certain of its property and equipment to reflect its fair value, pursuant to ASC 360), which were recorded in "Cost of goods sold" and "Other operating expense," respectively, in the Consolidated Statement of Operations. The fair value of the real property was derived based upon a market approach with substantial input from market participants, including brokers, investors, developers and appraisers. The fair value of the personal property was determined using a market approach based upon quoted market prices from auction data for comparable assets. Factors such as age, condition, capacity and manufacturer were considered to adjust the auction price and determine an orderly liquidation value of the personal property assets. The significant inputs related to valuing these assets are classified as Level 2 in the fair value measurement hierarchy. During fiscal 2020, the Company expects to record additional charges associated with these restructuring actions, including approximately $45.0 million to $55.0 million related to accelerated depreciation, approximately $5.0 million to $10.0 million related to employee termination benefits and approximately $5.0 million to $10.0 million related to other exit costs. During fiscal 2018, the Company initiated restructuring actions to improve operating efficiencies. As a result of these actions, the Company (1) recorded approximately $4.5 million of expenses primarily related to employee termination benefits in "Other operating expense" in the Consolidated Statement of Operations in fiscal 2019, (2) recorded approximately $18.7 million of expenses primarily related to employee termination benefits in "Other operating expense" in the Consolidated Statement of Operations in fiscal 2018, and (3) adjusted the carrying value of certain of its held for sale assets located in China and the U.S. to fair market value in fiscal 2018 (resulting in impairment charges totaling approximately $46.3 million, pursuant to ASC 360). The fair value of the assets was based on quotes from third parties. Primarily as a result of the Business Combination (see Note 6), during fiscal years 2019, 2018 and 2017, the Company recorded restructuring expenses (including employee termination benefits and ongoing expenses related to exited leased facilities) of approximately $1.3 million, $2.7 million and $2.1 million, respectively. As of March 30, 2019, the restructuring obligations associated with the above actions total $8.6 million (related to employee termination benefits of $7.0 million and lease termination costs of $1.6 million), and are included in "Accrued liabilities" and "Other long-term liabilities," respectively, in the Consolidated Balance Sheets. At March 31, 2018, the restructuring obligations related to the above actions totaled $6.1 million (related to employee termination benefits), and $2.6 million (related to lease termination costs) and are included in "Accrued liabilities" and "Other long-term liabilities," respectively, in the Consolidated Balance Sheets.
