Restructuring And Related Activities [Abstract]

6. Restructuring Charges

On November 29, 2019, following the completion of a strategic review of its business, the Company's Board of Directors approved a workforce reduction plan, or the Workforce Reduction, to reduce its workforce by approximately 38%. The Company evaluated the related employee severance and other benefits to employees in connection with the Workforce Reduction to determine whether the benefits were within the scope ASC 712, Compensation - Non-retirement Post-employment Benefits, or within the scope of ASC 420, Exit or Disposal Cost Obligations, depending on the nature of the benefit and whether it is part of an on-going benefit arrangement under ASC 712 or a one-time termination benefit unique to the Workforce Reduction. The Company recorded restructuring expense of $0.6 million at the time of the Workforce Reduction, pursuant to ASC 420 as the Company did not have an on-going benefit arrangement under ASC 712. The Workforce Reduction was complete as of December 31, 2019.
