The Company has operating leases in relation to property for office, manufacturing and research facilities. The maximum lease term without activation of termination options is to 2041.

On March 30, 2022, the Company entered into an agreement to modify the lease of 39 Innovation Drive, Milton Park, Abingdon, Oxfordshire, UK, and on June 15, 2022, the deeds associated with the modification were signed. However, for purposes of ASC 842 Leases, the Company determined that the effective date of the modification is March 30, 2022. The effect of the modification was a partial reduction of the scope of the lease and an increase in contractual lease payments relating to a non-lease component. The modification did not result in the identification of a separate contract but did result in the identification of a non-lease component relating to a leasehold improvement.

Upon modification, the lease liability has been remeasured using the current estimate of the Company’s incremental borrowing rate. The remeasurement of the lease liability also resulted in variable lease payments not previously included in the amount of the lease liability becoming included in the amount of the lease payments as at the date of the modification. The amount of the remeasurement of the lease liability due to the inclusion of variable lease payments that depend on an index or rate has been recognized as an adjustment to the corresponding right-of-use asset. The effect of the modification was to increase the lease liability and the corresponding right-of-use asset by $75,000.
