Income Tax Disclosure [Abstract] |
Income Taxes | 12. Income Taxes The Company determines its estimated annual effective tax rate at the end of each interim period based on full year forecasted pre-tax income and facts known at that time. The estimated annual effective tax rate is applied to the year-to-date pre-tax income at the end of each interim period with the cumulative effect of any changes in the estimated annual effective tax rate being recorded in the period in which the changes are determined. The tax effect of significant unusual items is reflected in the period in which they occur. Since the Company is incorporated in Canada, it is required to use Canada’s statutory tax rate of 29.0% in the determination of the estimated annual effective tax rate. The Company maintains a valuation allowance on deferred tax assets associated with certain U.S. state net operating losses, credits and certain non-U.S. tax attributes that the Company has determined are not more likely than not to be realized. A valuation allowance is required when, based upon an assessment of various factors, including recent operating loss history, anticipated future earnings, and prudent and reasonable tax planning strategies, it is more likely than not that some portion of the deferred tax assets will not be realized. In conjunction with the Company’s ongoing review of its actual results and anticipated future earnings, the Company continuously reassesses the possibility of adding a new or additional valuation allowance or releasing the valuation allowance currently in place on its deferred tax assets. The Company’s effective tax rate of 19.7% for the three months ended March 28, 2025 differs from the Canadian statutory tax rate of 29.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, estimated deductions for Foreign Derived Intangible Income, U.K. patent box deductions and R&D tax credits, partially offset by disallowed compensation deductions, withholding taxes, non-deductible expenses and an estimated Pillar Two inclusion. The Company’s effective tax rate of 13.2% for the three months ended March 29, 2024 differs from the Canadian statutory tax rate of 29.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, estimated deductions for Foreign Derived Intangible Income, U.K. patent box deductions, R&D tax credits and windfall tax benefits upon vesting of share-based compensation awards, partially offset by disallowed compensation deductions, uncertain tax position accruals, and estimated Pillar Two inclusion. For the three months ended March 29, 2024, the tax benefits upon vesting of certain share-based compensation awards had a benefit of 6.8% on the Company’s effective tax rate.
