Both ASC 718 (US GAAP) and IFRS 2 (IFRS) measure equity-settled awards at grant-date fair value and expense over the vesting period. The differences are in forfeitures, attribution, and deferred tax.
| Area | US GAAP (ASC 718) | IFRS (IFRS 2) |
|---|---|---|
| Forfeitures | Estimate, or recognize as they occur (policy election) | Must estimate |
| Graded vesting | Policy choice (straight-line or accelerated) for service conditions | Accelerated (each tranche treated separately) |
| Deferred tax | Based on cumulative book expense | Remeasured on intrinsic value each period |
