• Own delivery and substantive review of corporate accounting responsibilities, including equity, stock-based compensation and long-term debt entries, reconciliations and disclosures. Investigate missing or unsupported activity with Treasury and contributing teams. Coordinate accounting schedules for Tax's provisions and filings and review legal-entity financial statements and Canadian and U.S. statistical reporting within the role's responsibilities.
• Establish consistent accounting positions and review standards across corporate accounting and reporting. Review and challenge IFRS research, memoranda and recommendations prepared by the team for acquisitions, joint arrangements, revenue, impairment, leases and provisions; approve conclusions within delegated authority and elevate significant judgments to the Corporate Controller with a recommended approach.
