During January 2017, the Company entered into a five-year lease (the Existing Lease) for approximately 15,700 square feet for its corporate headquarters located in Hayward, California (the Existing Premises). The lease commenced during July 2017.

During May 2019, the Company entered into Lease Amendment 1 (the Amendment) in relation to the Existing Lease and added the lease of new premises of approximately 34,600 square feet (the Expansion Premises); additionally, the term of the Existing Lease was extended to October 2029.

The Company evaluated the Amendment under the provisions of ASC 842 that it adopted on January 1, 2019, and accounted for the Amendment as a single contract with the Existing Lease because the additional lease payments due to the Amendment was not commensurate with the right-of-use (ROU) asset granted to the Company. Though the Amendment was accounted for as a single contract, the Existing Premises and Expansion Premises are accounted for as separate lease components. Accordingly, the Company measured and allocated consideration to each lease component as of the modification date.

During May 2020, the Company took possession and commenced the final lease component of the Expansion Premises, which was originally anticipated to be occupied in April 2020. Taking possession of the Expansion Premises resulted in a change in payments for the entire lease. Accordingly, the lease components were remeasured as of the commencement date of the final lease component, and a corresponding ROU asset and lease liability was recorded. As of May 2020, all components under the Amendment are in use and will be co-terminous until October 2029.
