Restructuring

​

On October 10, 2022, we announced a reduction in our workforce primarily in our development and administration groups. All affected employees will be eligible to receive, among other things, specified severance payments based on the applicable employee’s level and years of service with us. We expect to complete the workforce reduction by January 31, 2023. We recognize restructuring charges when the liability is probable, and the amount is estimable. The related employee termination benefits are accrued at the date management has committed to a plan of termination and affected employees have been notified of their termination date and expected severance benefits. As such, we expect to recognize the restructuring charges in the fourth quarter of 2022.

Sublease Agreement

​

On October 28, 2022, we entered into a sublease agreement with Atara Biotherapeutics, Inc. (Atara) to sublease approximately 13,670 rentable square feet of office space located in South San Francisco, California. Subject to the terms of the sublease agreement, the lease term shall commence no sooner than November 1, 2022 and shall expire on May 24, 2025. The future lease payments associated with this sublease agreement are approximately $1.7 million. We expect this new leased facility will be held as our new Headquarters following the expiration of our current leased facility in South San Francisco, California in January 2023. In accordance with ASC 842, Leases, we expect to recognize the operating lease right-of-use asset and lease liability associated with this sublease agreement in the fourth quarter of 2022.
