Reorganizations [Abstract] |
Reorganizations | 8. Reorganizations June 2023 Reorganization In June 2023, we implemented a restructuring plan under which we provided employees one-time severance payments upon termination, continuation of benefits for a specific period of time, outplacement services and certain stock award modifications. The total amount incurred for these activities was $4.2 million, which primarily consists of severance payments to terminated employees. During the three months ended March 31, 2024, we paid $0.5 million of the total cash severance charges. As of March 31, 2024, we have completed payment of the cash severance charges. Executive Officer Departures During the second and third quarters of 2023, we also implemented changes to our executive leadership structure. In connection with these changes, we provided five executive officers with one-time severance payments upon termination, continued benefits for a specified period of time, and certain stock option modifications. The total expense for these activities was $13.4 million, $4.7 million of which was primarily for severance and $8.7 million of which was for non-cash, stock-based compensation expense, which was recognized in 2023. During the three months ended March 31, 2024, we paid $0.1 million of the total cash severance charges. As of March 31, 2024, we have completed payment of the cash severance charges. We have accounted for these expenses in accordance with the FASB ASC Topic 420, Exit or Disposal Cost Obligations.
