Subsequent Events [Abstract] |
Subsequent Events | 13. Subsequent Events On March 10, 2023, Silicon Valley Bank ("SVB") in the United States was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation ("FDIC") as receiver. On March 12, 2023, the U.S. Department of the Treasury, Federal Reserve, and FDIC jointly announced that the FDIC will complete its resolution of SVB in a manner that fully protects all depositors. As of March 10, 2023, we held $2.7 million in collateral money market accounts supporting letters of credit issued by SVB to the Landlord in connection with the Initial Lease Agreement and Additional Lease Agreement. We are working with the Landlord to replace the letters of credit issued by SVB with letters of credit from a different financial institution.
