What are the key differences between IFRS 16 and ASC 842 for lease accounting?

Question

Great question — lease accounting convergence got close but didn't fully align. Both IFRS 16 and ASC 842 require lessees to recognize a right-of-use (ROU) asset and a lease liability on the balance sheet for nearly all leases. The big differences lie in how expenses flow through the income statement.

**IFRS 16 (Lessee):**
- **Single model:** ALL leases are treated like finance leases
- Balance sheet: ROU asset + lease liability
- Income statement: Depreciation (on the ROU asset) + Interest expense (on the lease liability)
- Expense pattern: **Front-loaded** (higher total expense in early years because interest is calculated on a declining balance)
- Cash flow: Interest portion in operating or financing; principal portion in financing

**ASC 842 (US GAAP — Lessee):**
- **Dual model:** Leases are classified as either finance or operating
- Finance lease: Same as IFRS 16 — amortization + interest (front-loaded)
- Operating lease: **Single straight-line lease expense** — total expense is the same each period
- Operating lease cash flow: All payments typically in operating activities

**Key financial statement impacts:**

| Metric | IFRS 16 (All Leases) | ASC 842 Operating Lease |
|---|---|---|
| EBITDA | Higher (no lease expense above EBIT) | Higher (same treatment) |
| EBIT | Lower (depreciation deducted) | Higher (single lease expense below EBIT line) |
| Net income early years | Lower (front-loaded) | Same each year |
| Total expense over lease life | Identical | Identical |
| Debt ratios | Worse (liability on BS) | Worse (liability on BS) |

**Example:** Halcyon Retail signs a 5-year lease with annual payments of $100,000. Under IFRS 16, Year 1 expense might be $108,000 (higher depreciation + interest) while Year 5 might be $92,000. Under ASC 842 operating lease, every year shows exactly $100,000.

**Cross-border comparison trap:** When comparing a European company (IFRS) to a US company (US GAAP), EBITDA may appear similar, but EBIT will differ because IFRS always deducts ROU depreciation while ASC 842 operating leases don't.

**Exam tip:** CFA Level II often tests the income statement pattern difference and asks you to adjust financial statements for cross-border comparability.
