Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Interim period income tax expense or recovery is determined by multiplying the year-to-date earnings or losses before tax by management’s best estimate of the overall annual effective income tax rate, taking into account the tax effect of certain items recognized in the interim period. As a result, the effective income tax rates used in our interim financial statements may differ from management’s estimate of the annual effective tax rate for the annual financial statements. Our estimated annual effective income tax rate varies as the quarters progress, for various reasons, including as a result of the mix and volume of business in various tax jurisdictions within the Americas, Europe and Asia, in jurisdictions with tax holidays and tax incentives, and in jurisdictions for which a valuation allowance has been recognized to reduce net deferred tax assets to nil because management believes that it is more likely than not that the benefit will not be realized (i.e., based on our review of financial projections, no estimated future taxable profit will be available against which tax losses and deductible temporary differences could be utilized). Our annual effective income tax rate can also vary due to the impact of restructuring charges, foreign exchange fluctuations, operating losses, cash repatriations, and changes in our provisions related to tax uncertainties. In Q3 2025 and YTD 2025, our net income tax expense included $13.3 and $27.2 of income taxes, respectively, related to Pillar Two global minimum tax legislation in jurisdictions where we operate (GMT). Our Q3 2024 net income tax expense included $2.6 of income taxes related to GMT. Our YTD 2024 net income tax expense included an $18.8 income taxes related to GMT, offset in part by the recognition of $7.5 of previously unrecognized deferred tax assets in our U.S. group of subsidiaries as a result of our NCS acquisition and $5.6 of reversals of tax uncertainties relating to one of our Asian subsidiaries.
