2018 Restructuring

The Company announced and began executing a reduction-in-force in its third and fourth fiscal quarters as a result of the acquisitions of the Campus Fabric Business and the Data Center Business. The Company recorded $7.9 million related to employee severance and benefits expenses during the year ended June 30, 2018.

2017 Restructuring

In conjunction with the Company’s restructuring activities noted below, the Company incurred $8.9 million of restructuring charges, net of reversals during fiscal 2017 which is reflected in “Restructuring and related charges, net of reversals” in the consolidated statements of operations.

Pursuant with the WLAN Business acquisition from Zebra, the Company assumed a facility lease located at 6480 Via del Oro in San Jose, California (“Via del Oro”) and transferred the Company’s headquarters from Rio Robles Drive in San Jose, California (“Rio Robles”) to Via del Oro. The Company consolidated its existing workforce with employees assumed from Zebra at the Via del Oro site and exited the Rio Robles site on January 31, 2017. Due to the Company’s move from the Rio Robles facility and abandonment of all leasehold improvements, it accelerated the amortization of the remaining leasehold improvements balance for this site over the shortened service period such that the leasehold improvements were fully amortized on the cease-use date. The Company recorded accelerated amortization expense for the year ended June 30, 2018 of $2.6 million.

The Company entered into a sublease agreement for its Rio Robles facility during the third quarter of fiscal 2017. The sublease is for the remaining duration of the Company’s lease. The net charges incurred for the remaining lease payments, real estate commissions and other related costs, net of the future sublease payments resulted in additional charges of $2.0 million during fiscal 2017. The excess facilities payments will continue through fiscal year 2023.

In anticipation of the acquisitions of the Campus Fabric and the Data Center Businesses, the Company reoccupied the majority of its exited space at its Salem, New Hampshire location during its fiscal fourth quarter to accommodate the growth in headcount and lab facility requirements. This action resulted in a reversal of prior accruals of $1.3 million.

In conjunction with the consolidation actions noted above, the Company announced a reduction-in-force affecting 90 employees. The Company recorded $5.6 million in severance and benefits charges, net during the year ended June 30, 2017.
