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 and at March 31, 2018, the Company is not able to estimate the total or future amount of expected employee separation or exit costs that it will incur in connection with its restructuring activities.

During fiscal 2018, the Company incurred expenses including non-restructuring contract exit costs of $19.5 million for fees associated with transitioning from the public utility provider in Oregon to a lower cost direct access provider. The fee is paid monthly and will depend on the amount of actual energy consumed by the Company's wafer fabrication facility in Oregon over the next five years. In connection with the transition to a direct access provider, the Company signed a ten-year supply agreement to purchase monthly amounts of energy that are less than the current average usage and priced on a per mega watt hour published index rate in effect at those future dates. Also during fiscal 2018, the Company incurred $1.2 million of employee separation costs in connection with the acquisition of Atmel. The Company may continue to incur additional costs in the future as additional synergies or operational efficiencies are identified. The Company is not able to estimate the amount of such future expenses, if any, at this time.

The Company's restructuring expenses during fiscal 2017 were related to the Company's most recent business combinations, including the acquisitions of Atmel and Micrel, and resulted from workforce, property and other operating expense rationalizations as well as combining product roadmaps and manufacturing operations. These expenses were for employee separation costs, contract exit costs, other operating expenses and intangible asset impairment losses. At March 31, 2017, these activities were substantially complete.

All of the Company's restructuring activities occurred in its semiconductor products segment. The Company incurred $52.2 million in costs since the start of fiscal 2015 in connection with employee separation activities, of which $1.2 million, $39.1 million and $9.6 million was incurred during the fiscal years ended March 31, 2018, 2017 and 2016, respectively. These employee separation activities are now substantially complete and any future amounts are not expected to be material. The Company has incurred $45.3 million in costs in connection with contract exit activities since the start of fiscal 2015 which includes $0.7 million, $44.1 million and $0.7 million incurred for the years ended March 31, 2018, 2017 and 2016, respectively. These acquisition-related contract exit activities are substantially complete and any future amounts are not expected to be material.

In the three months ended June 30, 2017, the Company completed the sale of an asset it acquired as part of its acquisition of Micrel for proceeds of $10.0 million and the gain of $4.4 million is included in the gain on sale of assets in the above table. As of March 31, 2017, these assets consisting of property, plant and equipment were presented as held for sale in the Company's consolidated financial statements.

The impairment charges in fiscal 2017 were recognized as a result of changes in the combined product roadmaps after the acquisition of Atmel that affected the use and life of these assets.
