The Company is subject to taxation primarily in Canada, the United States, and Australia. Further, while the statute of limitations in each jurisdiction where an income tax return has been filed generally limits the examination period, the limitation period for examination by a jurisdiction may be extended under various provisions. Generally, tax years ranging from 2021 to 2025 remain open to income tax examination. Other than routine audits done by tax authorities, management is not aware of any other material income tax assessments arising from examinations currently in progress by any taxing jurisdiction.
