Aptose leases office space in San Diego, California and Toronto, Canada. On November 4, 2022, the lease for the San Diego office space was extended through May 31, 2026 (the "Third Amendment"). Management has determined that the Third Amendment represents a lease modification, as defined by ASC 842, Leases, does not meet the requirements for accounting as a separate contract and continues to meet the definition of an operating lease. The lease for the Toronto, Canada office space was extended for one year on February 23, 2023, with this extension expiring on June 30, 2024. The Company has not included any extension periods in calculating its right-to-use assets and lease liabilities. Aptose previously leased lab space in San Diego, which we exited prior to the expiration of the lease on February 28, 2023. The costs incurred in exiting this laboratory space were not material. The Company also enters into leases for small office equipment.
