Commitments and Contingencies

Commitments and ContingenciesOn June 30, 2020, the Company entered into an amended and restated lease agreement (the “Amended and Restated Lease”) for office and laboratory space located in San Diego, California, for the Company’s current corporate headquarters, which supercedes the original lease agreement dated August 22, 2019. The Amended and Restated Lease has a lease term of 12 years (“Lease Term”), unless terminated earlier. The Lease Term has an initial abatement period, and the initial base rent payable will be approximately $0.6 million per month following the abatement period, which amount will increase by 3% per year over the Lease Term. The Company also received incentives from the landlord for tenant improvements. During 2020, the underlying asset was available for use by the Company to construct tenant improvements and therefore, the Lease Term was considered to have commenced. The Amended and Restated Lease is considered to be an operating lease, and the Company used a discount rate of 12% to calculate the value of its lease payments over the Lease Term. As of March 31, 2023, the condensed consolidated balance sheet includes an operating right-of-use asset of $35.8 million and a total operating lease liability of $51.1 million, of which $7.9 million is a current lease liability and included in accrued liabilities, and $43.2 million is included in non-current lease liability. As of December 31, 2022, the condensed consolidated balance sheet includes an operating right-of-use asset of $36.1 million and a total operating lease liability of $51.5 million, of which $7.8 million is a current lease liability and included in accrued liabilities, and $43.7 million is included in non-current lease liability. For the three months ended March 31, 2023 and 2022, the Company recorded operating lease expense of $2.0 million and $1.9 million, respectively.

As of March 31, 2023, the approximate future minimum lease payments under the Amended and Restated Lease are as follows (in thousands):

	Operating Lease
Remainder of 2023	$	5,926
2024	8,080
2025	8,322
