BASIS OF PREPARATION |
BASIS OF PREPARATION | 2. BASIS OF PREPARATION (a) Statement of Compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). During 2021, the company revised the presentation of certain expenses from “transportation” to “transportation and distribution” and reclassified certain operating, selling and general expenses to transportation and distribution to better reflect the nature of these expenses. There is no impact on net earnings (loss) and comparative periods have been restated to reflect this change. Suncor’s accounting policies are based on IFRS issued and outstanding for all periods presented in these consolidated financial statements. These consolidated financial statements were approved by the Board of Directors on February 23, 2022. (b) Basis of Measurement The consolidated financial statements are prepared on a historical cost basis except as detailed in the accounting policies disclosed in note 3. The accounting policies described in note 3 have been applied consistently to all periods presented in these consolidated financial statements. (c) Functional Currency and Presentation Currency These consolidated financial statements are presented in Canadian dollars, which is the company’s functional currency. (d) Use of Estimates, Assumptions and Judgments The timely preparation of financial statements requires that management make estimates and assumptions and use judgment. Accordingly, actual results may differ from estimated amounts as future confirming events occur. Significant estimates and judgments used in the preparation of the consolidated financial statements are described in note 4.
