On July 4, 2025, the “One Big Beautiful Bill Act” (“OBBBA”) was enacted into law. The OBBBA provides for modifications to U.S. tax law including changes to interest deductibility, R&D expensing, bonus depreciation, and various international provisions. The OBBBA did not have a material impact on our financial statements for 2025 and we do not expect a material impact going forward.
We adopted guidance that expands income tax disclosures, including requiring enhanced disclosures related to the rate reconciliation and income taxes paid information, effective January 1, 2025, on a prospective basis. The Canadian federal statutory rate used is 25%. This rate results in the 10% federal tax abatement being included in the ‘Provincial income taxes, net of federal abatement’ line. Our disclosures reflect the application of this new guidance beginning in 2025, while our disclosures for prior periods were prepared under the guidance of the previous standards. The statutory rate reconciles to the effective income tax rate as follows:

Companies subject to the Global Intangible Low-Taxed Income provision (GILTI) have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for outside basis temporary differences expected to reverse as GILTI. We have elected to account for GILTI as a period cost.

We are generally permanently reinvested on any potential outside basis differences except for unremitted earnings and profits and thus do not record a deferred tax liability for such outside basis differences. To the extent of unremitted earnings and profits, we generally review various factors including, but not limited to, forecasts and budgets of financial needs of cash for working capital, liquidity and expected cash requirements to fund our various obligations and record deferred taxes to the extent we expect to distribute. The determination of the unrecorded deferred tax liability amount is not practicable.
We had $70 million and $44 million of unrecognized tax benefits at December 31, 2025 and December 31, 2024, respectively, which if recognized, would favorably affect the effective income tax rate. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in millions):

We recognize interest and penalties related to unrecognized tax benefits in income tax expense. The total amount of accrued interest and penalties was $18 million and $12 million at December 31, 2025 and 2024, respectively. Potential interest and penalties associated with uncertain tax positions in various jurisdictions recognized was $5 million during 2025, $3 million during 2024, and $4 million during 2023. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax provision.
We file income tax returns with Canada and its provinces and territories. Generally, we are subject to routine examinations by the Canada Revenue Agency (“CRA”). The CRA is conducting examinations of the 2015 through 2020 taxation years. Additionally, income tax returns filed with various provincial jurisdictions are generally open to examination for periods up to six years subsequent to the filing and assessment of the respective return.
In connection with an ongoing tax audit, we have had discussions with the Canada Revenue Agency (“CRA”) regarding our deductions of certain intercompany dividends in taxation years 2015 through 2018. We believe our tax position with respect to this matter is appropriate, as such no reserve has been recorded in the consolidated financial statements with respect to this matter.
We also file income tax returns, including returns for our subsidiaries, with U.S. federal, U.S. state, and other foreign jurisdictions. We are subject to routine examination by taxing authorities in the U.S. jurisdictions, as well as other foreign tax jurisdictions. Taxable years of such U.S. companies are closed through 2021 for U.S. federal income tax purposes. We have various U.S. federal, state and other foreign income tax returns in the process of examination. From time to time, these audits result in proposed assessments where the ultimate resolution may result in owing additional taxes. We believe that our tax positions comply with applicable tax law and that we have adequately provided for these matters.

About Income Taxes Disclosures

The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.

Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
