Income taxes | Note 11. Income taxes The Canada Revenue Agency (CRA) has reassessed CIBC’s 2011–2019 taxation years for approximately $ 1,847 million of income taxes related to the denial of deductions of certain dividends. Subsequent taxation years may also be similarly reassessed. CIBC filed a Notice of Appeal in respect of its 2011 taxation year to put the matter in litigation. CIBC is confident that its tax filing positions are appropriate and intends to defend itself vigorously. Accordingly, no amounts have been accrued in the interim consolidated financial statements. As previously reported, potential aggregate exposure remaining in respect of foreign exchange capital loss matters is approximately $ 76 million. No amounts have been accrued in the interim consolidated financial statements. On June 20, 2024, Canada enacted the Global Minimum Tax Act (GMTA) to adopt the Organisation for Economic Co-operation and Development’s (OECD) Pillar Two, which implements a 15 % global minimum corporate tax on certain multinational enterprises (GMT). GMT is in different stages of adoption globally. Certain jurisdictions in which we operate have implemented GMT, which applied to CIBC as of November 1, 2024. The impact of GMT on the consolidated effective tax rate is within a 1 % range in the first quarter of 2025.
