Restructuring	14. Restructuring On April 19, 2016, the FDA notified the Company that the SurgiBot System did not meet the criteria for substantial equivalence based on the data submitted in the 510(k) submission. As a result, the Company has reprioritized its efforts to focus on the commercialization of and regulatory clearance for the ALF-X System. Consequently, in May 2016, the Company implemented a restructuring plan. Under the restructuring plan, the Company reduced headcount, discontinued efforts on the SurgiBot System, and cancelled certain contracts. The restructuring charges amounted to $5.7 million, of which $2.6 million was included as inventory write down related to restructuring and $3.1 million was included as restructuring and other charges in the consolidated statements of operations and comprehensive loss, during the second quarter of 2016. The restructuring and other charges of $3.1 million included: (i) $0.5 million to be paid in cash, of which $0.4 million related to employee severance costs and $0.1 million related to cancellation of certain contracts; and (ii) $2.6 million for other non-cash charges, of which $1.0 million related to the disposal of long-lived assets for the abandonment of certain equipment and tooling directly relating to the SurgiBot System and $1.6 million related to the write-off of intellectual property for certain patents also relating to the SurgiBot System. The Company does not anticipate additional restructuring charges in 2016. The total future payments under the restructuring plan as of June 30, 2016 included in accrued expenses in the consolidated balance sheet as of June 30, 2016 are $199,000.
