Restructuring, Impairment and Disposal Charges
Restructuring Charges
The following is a summary of significant restructuring expense recognized in continuing operations, primarily in operating expenses:
•
During fiscal year 2019, we initiated cost reduction activities associated with the CA Merger. As a result, we recognized $740 million of restructuring expense primarily related to employee termination and lease and other exit costs during fiscal year 2019. We expect these restructuring activities to be substantially completed by the end of fiscal year 2020.
•
During fiscal year 2018, we initiated cost reduction activities associated with the Brocade Merger. As a result, we recognized $2 million and $176 million of restructuring expense in fiscal years 2019 and 2018, respectively. These charges primarily related to employee termination costs. We have substantially completed the restructuring activities related to the acquisition of Brocade.
•
In connection with cost reduction activities associated with the acquisition of BRCM, we recognized $4 million, $50 million and $124 million of restructuring expense in fiscal years 2019, 2018 and 2017, respectively. These restructuring expenses primarily related to lease and other exit costs for fiscal years 2019 and 2018 and employee termination costs for fiscal year 2017. We have substantially completed the restructuring activities related to the acquisition of BRCM.
