Deferred tax assets have not been recognized in respect of these temporary differences and losses, as well as foreign tax credits of $3.9 (2022 - $4.0), because they are restricted to certain jurisdictions and cannot be used elsewhere in the Company at this time. The OECD introduced a global minimum tax of 15% which is widely referred to as the "Pillar Two" global minimum tax regime (Pillar Two tax regime). Under the Pillar Two tax regime, the Company may be liable to pay top-up taxes for operations in jurisdictions with effective tax rates of less than 15%, that have enacted the legislation. The Company is expected to be within the scope of the Pillar Two tax regime as Canada released draft Pillar Two legislation which is expected to come into effect in 2024. As of December 31, 2023, the United Kingdom and the European Union are the only jurisdictions the Company operates in that have enacted or substantively enacted the tax legislation related to Pillar Two. The Company is currently in the process of assessing the potential impact, including the application of the transitional safe harbor rules. Based on the current assessment, most entities within the Company are expected to either have an effective tax rate that exceeds 15%, or to meet the transitional safe harbor rules such that no top-up tax would apply. The quantitative impact of the enacted or substantively enacted legislation is not yet reasonably estimable due to the complexities of applying the legislation. Also, as the Pillar Two legislation comes into effect after December 31, 2023, there is currently no related current tax exposure. The Company will continue to monitor the developments in applying the legislation as well as the tax legislative changes in jurisdictions the Company operates in.
