Restructuring Charges

During the year ended December 31, 2015, we incurred restructuring charges related to: (i) an agreement with Dr. Lopez, a member of our Board of Directors and a former employee in our research and development department, pursuant to which we bought out Dr. Lopez's right to employment under his then-existing employment agreement; (ii) the reorganization of our corporate infrastructure, resulting in one-time employee termination benefits and other associated costs; and (iii) a commitment to a plan to sell our Slovakia manufacturing facility. The assets of the manufacturing facility are classified as assets held for sale and are included as a separate line item in our condensed consolidated balance sheet. The sale is expected to be completed during the last quarter of 2016. The plan to close the facility resulted in a pre-tax restructuring charge for employee termination benefits, government incentive repayments and other associated costs. There was $0.4 million and $0.8 million in restructuring charges incurred for the three and nine months ended September 30, 2016, respectively. Of these charges, for the nine months ended September 30, 2016 $0.6 million were related to the closure of the Slovakian manufacturing facility and are included in the below table, and the other $0.2 million was related to a one-time charge unrelated to the events disclosed above.

The following table summarizes the details of changes in our restructuring-related accrual for the period ending September 30, 2016 (in thousands):
