Subsequent Events [Abstract]
Subsequent event	Subsequent event On March 10, 2023, Silicon Valley Bank ("SVB") was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation ("FDIC") as receiver. On March 9, 2023, the Company transferred a substantial portion of its cash and cash equivalents from SVB to other financial institutions. The Company had total cash and cash equivalents of approximately $170 million as of March 10, 2023. On March 12, 2023, a Joint Statement by the U.S. Treasury, Federal Reserve, and FDIC, and a statement by the Federal Reserve Board, was issued stating that actions were approved enabling the FDIC to complete its resolutions of SVB in a manner that fully protects all depositors. As a result of actions taken by the Company to move a substantial portion of its cash to other financial institutions and the actions taken by the FDIC on March 12, 2023, the Company has determined that all of its cash and cash equivalents continue to be available for use by the Company. The Company is also party to the Third SVB Facility which contains certain restrictive covenants including a covenant that limits the Company's ability to retain specified levels of cash in accounts outside of SVB. On March 10, 2023, in connection with the transfer of a substantial portion of the Company’s cash and cash equivalents from SVB to other financial institutions, the Company obtained consent from SVB to hold up to $165 million of cash in accounts outside SVB until May 15, 2023. The consent serves to permit the Company to borrow against the Third SVB Facility once the cash and cash equivalents retained outside of SVB are compliant with the covenant and so long as the company remains in compliance with all other covenants under the Third SVB Facility. With the exception of this consent, the SVB developments and related FDIC actions noted above have not materially impacted the Company's financial position or its operations. Management believes that the Company’s cash and cash equivalents along with cash generated in the normal course of business, are sufficient to fund its operations for at least the next 12 months.
