On November 6, 2018, the Company’s Board of Directors approved an additional restructuring plan to further reduce operating costs. Under the restructuring plan, the Company reduced its workforce by 16 employees, including its Chief Operating Officer, Mr. Lloyd Mackenzie, effective December 31, 2018. Further reduction of staff may occur in 2019 pending corporate development activities. Affected employees are eligible to receive severance payments and outplacement services. The Company estimates that for this second restructuring plan, it will incur aggregate restructuring charges of approximately $1.0 million in 2018 related to one-time termination severance payments and other employee-related costs. The charges that the Company expects to incur in connection with this restructuring plan are subject to a number of assumptions, and actual results may differ materially. The Company may also incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the restructuring plan.
