We have a sublease agreement with Atara Biotherapeutics, Inc. (Atara) entered in October 2022 to sublease an office space located in South San Francisco, California. Subject to the terms of the sublease agreement, the lease term commenced in November 2022 and shall expire in May 2025. This leased facility is currently held as our new headquarters following the expiration of our previously leased facility in January 2023. At lease measurement date in the fourth quarter of 2022, we recognized the operating lease right-of-use asset and lease liability of approximately $1.3 million. As of June 30, 2023, we recorded $0.2 million of lease incentives from our sublease with Atara, which we recorded as a reduction to operating lease right-of-use asset and lease liability until the lease ends and the asset is transferred. The weighted average remaining term of our leases as of June 30, 2023 was 1.92 years.

We had a lease agreement with Healthpeak Properties, Inc. (formerly known as HCP BTC, LLC), to occupy research and office space located in South San Francisco, California and a sublease agreement with an unrelated third-party to sublet a portion of the leased facility. Both leases expired in January 2023.
