On February 14, 2018, the Company acquired 3VR. As a result of the acquisition, during the year ended December 31, 2018, the Company incurred restructuring and severance expenses of $618,000, consisting of facility rental related costs of $290,000 and severance related costs of $328,000. In addition, in the fourth quarter of 2018, the Company recorded a restructuring accrual of $129,000 for its future rental payment obligation associated with vacated office space at its Fremont, California facility. 

During the year ended December 31, 2019, the Company incurred restructuring and severance related costs of $105,000. These costs were partially offset by the reversal of the remaining restructuring accrual of $91,000 associated with the previously vacated office space disclosed above which was sublet in the third quarter of 2019.
