The Company continuously evaluates its existing operations in an attempt to identify and realize cost savings opportunities and operational efficiencies. This same approach is applied to businesses that are acquired by the Company and often the operating models of acquired companies are not as efficient as the Company's operating model which enables the Company to realize significant savings and efficiencies. As a result, following an acquisition, the Company will from time to time incur restructuring expenses; however, the Company is often not able to estimate the timing or amount of such costs in advance of the period in which they occur. The primary reason for this is that the Company regularly reviews and evaluates each position, contract and expense against the Company's strategic objectives, long-term operating targets and other operational priorities. Decisions related to restructuring activities are made on a "rolling basis" during the course of the integration of an acquisition whereby department managers, executives and other leaders work together to evaluate each of these expenses and make recommendations. As a result of this approach, at the time of an acquisition, the Company is not able to estimate the future amount of expected employee separation or exit costs that it will incur in connection with its restructuring activities.

During the fiscal year ended March 31, 2021, the Company incurred net costs of $15.0 million associated with restructuring certain of its wafer fabrication operations consisting of $8.0 million to re-purpose its Colorado Springs (Fab 5) facility and $7.0 million associated with restructuring other acquired operations compared to net costs of $18.0 million during the fiscal year ended March 31, 2020 to re-purpose its Fab 5 facility, primarily consisting of $8.2 million in contract exit costs, $6.6 million in other relocation costs and $2.5 million in asset impairment charges. These wafer fabrication restructuring efforts were substantially completed as of March 31, 2021. The Company's other restructuring activities during the fiscal years ended March 31, 2021, March 31, 2020 and March 31, 2019 were primarily related to the Company's most recent business acquisitions, and resulted from workforce, property and other operating expense rationalizations as well as combining product roadmaps and manufacturing operations. The impairment charges in the fiscal year ended March 31, 2019 were primarily recognized as a result of writing off intangible assets purchased from Microsemi prior to the close of the acquisition and other intangible assets that were impaired as a result of changes in the combined product roadmaps after the acquisition that affected the use and life of the assets. Additional costs will be incurred in the future as additional synergies or operational efficiencies are identified in connection with the Microsemi transaction, other previous acquisitions, or the restructuring of wafer fabrication operations. The Company is not able to estimate the amount of other such future expenses at this time.

During the fiscal year ended March 31, 2020, the Company incurred $15.7 million of net charges related to legal settlements, for which the majority of the cash settlement occurred early in the fiscal year ended March 31, 2021.

All of the Company's restructuring activities occurred in its semiconductor products segment. The Company incurred $71.2 million in costs since the start of the fiscal year ended March 31, 2018 in connection with employee separation activities net of $1.3 million in credits during the fiscal year ended March 31, 2021 and $6.0 million and $65.3 million were incurred during the fiscal years ended March 31, 2020 and 2019, respectively. The Company could incur future expenses as additional synergies or operational efficiencies are identified. Beyond what is already accrued, the Company is not able to estimate future expenses, if any, to be incurred in employee separation costs. The Company has incurred $0.4 million in net credits in connection with contract exit activities since the start of the fiscal year ended March 31, 2018 which includes net credits of $1.6 million and $4.7 million for the fiscal years ended March 31, 2021 and March 31, 2019, respectively, compared to expense of $5.2 million for the fiscal year ended March 31, 2020.

The liability for restructuring and other exit costs of $15.9 million is included in accrued liabilities and other long-term liabilities, on the Company's consolidated balance sheets as of March 31, 2021.
