Restructuring Charges

During 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 consolidated balance sheet. The sale is expected to be completed during the third quarter of 2016. The plan to sell the facility resulted in a pre-tax restructuring charge for employee termination benefits, government incentive repayments and other associated costs. There were no restructuring charges incurred for the period ended March 31, 2016.

The following table summarizes the details of changes in our restructuring-related accrual for the period ending March 31, 2016 (in thousands):
