RESTRUCTURING CHARGES

RESTRUCTURING CHARGES:

In connection with the discontinuation of its 1550nm silicon photonics development activities, the Company initiated a restructuring plan in the first quarter of 2018 to wind down the business operations related to these activities, which primarily included terminating employees, exiting contracts with vendors, selling assets, and exiting facilities. The Company recorded $3.5 million, $3.4 million, and $3.4 million of employee separation and severance costs, contract exit costs with vendors, and impairment charges or losses on disposal of assets during the nine months ended September 30, 2018, respectively. The Company does not expect any significant restructuring charges in the future.
