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, and a right of use asset and lease liability of $953 was initially recorded for the fixed payments. Subsequent to December 31, 2023, the contingency related to the variable costs was resolved which resulted in an additional $4,350 in fixed undiscounted lease payments which will be made through the end of the lease. The Company may terminate for convenience with six months’ prior written notice and a $1,080 termination fee, the Dedicated Suite lease if both the CABA-201 and MuSK-CAART work orders are terminated.
