The Company has entered into a number of operating leases, primarily for office space and commercial property. These leases have remaining terms which range from 1.16 years to 1.59 years. The renewal option on one lease was exercised in February 2022 for an additional period of three years, extending this lease term to June 2025. The renewal option on another lease was derecognized in June 2022 as it was no longer reasonably certain that the option would be exercised, resulting in a reduction in the remaining term from 16 to six years. A Deed of Assignment was signed in August 2023 in relation to this lease and accordingly the related Right of Use asset and lease liability were derecognized. In September 2020, the Company entered into a sublease agreement for a commercial unit. This sublease agreement was assigned with the related lease in August 2023.

In November 2021, the Company entered into a 12-month lease, with a rolling extension, for office space, and in May 2022, the Company entered into a 6-month lease for office space, which was extended to November 2023 and elected not to apply the measurement and recognition requirements of ASC 842 to these short-term leases as any renewal term exercised or considered reasonably certain of exercise by the Company did not extend more than 12 months from the end of the previously determined lease term. In August 2023, the Company extended the lease agreements for a further nine months, with a rolling extension, and twelve months, respectively. While neither of the extended agreements extend more than 12 months from the end of the previously determined lease term, it is considered to be reasonably certain that these lease arrangements will be extended beyond a period of more than 12 months. Accordingly, the Company has applied the measurement and recognition requirements of ASC 842 to these lease arrangements.

Certain leases contain variable lease payments, including payments based on an index or rate. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement. Certain agreements contain both lease and non-lease components. The Company has elected to separately account for these components in determining the lease liabilities and right-of-use assets. The Company’s lease agreements generally do not provide an implicit borrowing rate; therefore, an internal incremental borrowing rate was determined based on information available at lease commencement date for the purposes of determining the present value of lease payments. The Company used the incremental borrowing rate on January 1, 2019 for all leases that commenced prior to that date.

All operating lease expenses are recognized on a straight-line basis over the lease term. The Company recognized $363, $753 and $1,009 of operating lease costs for right-of-use assets during the years ended December 31, 2023, 2022 and 2021, respectively. The Company recognized $194 and $243 of rental expenses on short-term leases during the years ended December 31, 2023 and 2022, respectively. The Company recognized $199, $293 and $335 of sublease income during the years ended December 31, 2023, 2022 and 2021, respectively.
