Use this skill whenever a preparer or reviewer needs to reconcile financial statements between IFRS Accounting Standards and a local GAAP. Trigger on phrases like "IFRS to US GAAP", "GAAP differences", "IFRS reconciliation", "first-time adoption IFRS 1", "ASC 842 vs IFRS 16", "ASC 606 vs IFRS 15", "ASC 326 CECL vs IFRS 9 ECL", "IAS 12 vs ASC 740", "Indian Ind AS", "Chinese ASBE", "Japanese J-GAAP", "Brazilian CPC", "Italian OIC", "German HGB", "UK FRS 102", "convergence", "EBIT vs operating profit", or any request to identify, quantify, or document a difference between IFRS and a national accounting framework. Covers the major reconciliation differences between IFRS and: US GAAP (ASC), German HGB, UK FRS 102, Italian OIC, French PCG, Indian Ind AS, Chinese ASBE 2006/2014, Japanese J-GAAP, Brazilian CPC (pre/post full IFRS adoption), Canadian ASPE (private enterprises). Does NOT cover: tax accounting (only the IAS 12 / ASC 740 deferred-tax differences are flagged), audit opinion construction, or local statutory filing mechanics. ALWAYS read this skill before booking an IFRS-to-local-GAAP adjustment or producing comparative financial statements.

Revenue recognition — IFRS vs US GAAP vs Other GAAP (IFRS 15 / ASC 606)
| Topic | IFRS | US GAAP | Other GAAP |
|---|---|---|---|
| Standard | IFRS 15 | ASC 606 | HGB: realisation principle (§252(1)4 HGB) — narrower; FRS 102 §23 — IFRS-aligned; J-GAAP: substantively converged 2018 |
| Variable consideration | Estimated and constrained (expected value or most likely) | Same (ASC 606 was joint project) | HGB: realised only when claim is enforceable |
| Licences (right to use vs right to access) | Point in time vs over time | Same | HGB: revenue at delivery |
| Contract costs (commissions) | Capitalise if recoverable; amortise (IFRS 15 ¶91-94) | Same (ASC 340-40) | HGB: expense as incurred |
| Principal vs agent | Control of specified good/service before transfer | Same | Generally consistent |
Typical adjustment: none if both IFRS 15 and ASC 606 are properly applied; differences emerge in transition period adjustments (modified retrospective vs full retrospective).
Leases — IFRS 16 vs ASC 842 (IFRS 16 / ASC 842)
| Topic | IFRS 16 | ASC 842 |
|---|---|---|

| P&L pattern | Depreciation + interest (front-loaded total) | Operating: straight-line lease expense; Finance: depreciation + interest |
| Lessor model | Substantially converged with ASC 840/842 | Substantially converged with IFRS 16 |

Leases — IFRS 16 vs ASC 842
| Topic | IFRS 16 | ASC 842 | |---|---|---| | Lessee model | Single model: capitalise all leases ≥ 12 months and > USD 5,000 with ROU asset and lease liability | Dual model: Finance leases (similar to IFRS 16) and Operating leases (ROU asset but straight-line P&L expense) | | P&L pattern | Depreciation + interest (front-loaded total) | Operating: straight-line lease expense; Finance: depreciation + interest | | Lessor model | Substantially converged with ASC 840/842 | Substantially converged with IFRS 16 | | Sale-and-leaseback | Recognise gain only to extent of rights transferred | Subtle measurement difference where leaseback at off-market terms |IFRS 16 / ASC 842
Recurring P&L difference
**[T1] Recurring P&L difference:** under ASC 842 operating leases, lessees report straight-line rent; under IFRS 16 the same lease produces front-loaded expense. EBITDA differs.[T1]
IFRS 16 vs FRS 102
| Topic | IFRS 16 vs FRS 102 | |---|---| | FRS 102 (UK private) | Section 20 retains the operating-vs-finance distinction; no ROU asset for operating leases. Material difference on transition from IFRS to FRS 102 (e.g., for groups moving to UK private status). |
IFRS 16 vs HGB
| Topic | IFRS 16 vs HGB | |---|---| | HGB | Lessee accounting follows economic ownership tests (BilMoG). Most operating leases remain off-balance-sheet — significant difference vs IFRS 16. |

Quantitative difference
**[T1] Quantitative difference:** ASC 326 generally produces higher day-one allowances because lifetime ECL applies from origination. IFRS 9 day-one allowance is 12-month ECL only.[T1]
Financial instruments classification — IFRS 9 vs ASC 320/321/825

Recurring difference note
