A near-term divergence to plan for: IFRS 18 (effective annual periods from 1 January 2027, replacing IAS 1) restructures income-statement presentation, while US GAAP (ASC 205 / 220) keeps its existing, more flexible approach.
| Area | US GAAP (ASC 205 / 220) | IFRS (IFRS 18, from 2027) |
|---|---|---|
| P&L categories | No prescribed categories | Defined categories — operating, investing, financing |
| Required subtotals | Limited | Operating profit (and others) required |
| Management-defined performance measures (MPMs) | Outside the statements (non-GAAP, SEC rules) | Disclosed within the IFRS statements, reconciled |
| Aggregation / disaggregation | General | Explicit principles |
IFRS 18 brings “non-GAAP-style” measures inside the audited statements and imposes a defined operating-profit subtotal — there is no equivalent US restructuring.
