Work orders terms The terms of the August 2023 work orders included both fixed costs and contingent variable costs. The lease commenced October 1, 2023. In 2024, the Company remeasured the lease due to resolution of the contingency related to variable costs and an amendment to the 2023 work order to extend the term of the agreement for an additional 18 months through August 2026 resulting in an increase in the right-of-use asset and lease liability of $10,963. The Company may terminate the Dedicated Suite lease for convenience with six months’ prior written notice and up to a $1,080 termination fee if both the rese-cel and MuSK-CAART work orders are terminated
