A new presentation standard — replacing IAS 1
IFRS 18 introduces mandatory categories for the income statement, two new defined subtotals, and clear requirements for how Management-Defined Performance Measures (MPMs) must be disclosed. It does not change the recognition or measurement of assets and liabilities. But it fundamentally changes how financial performance is presented and communicated.
