| 9 | ## Part 1: Lease Identification |
| 10 | |
| 11 | ### What Constitutes a Lease (ASC 842 / IFRS 16) |
| 12 | |
| 13 | Under both ASC 842 (842-10-15-9) and IFRS 16 (paragraph 9), a contract contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. |
| 14 | |
| 15 | **Three criteria must all be met:** |
| 16 | |
| 17 | | Criterion | ASC 842 Reference | IFRS 16 Reference | |
| 18 | |---|---|---| |
| 19 | | Identified asset (specific, not substitutable) | 842-10-15-3 | IFRS 16.B13–B20 | |
| 20 | | Customer has right to obtain substantially all economic benefits | 842-10-15-20 | IFRS 16.B21–B23 | |
| 21 | | Customer has right to direct use of the identified asset | 842-10-15-24 | IFRS 16.B24–B30 | |
| 22 | |
| 23 | **Supplier substitution right**: If the supplier has a substantive right to substitute the asset throughout the period of use, there is no identified asset and no lease. A substitution right is substantive only if the supplier (a) has the practical ability to substitute and (b) would benefit economically from doing so. (ASC 842-10-15-10; IFRS 16.B14) |
| 24 | |
| 25 | ### Practical Expedient — Lease and Non-Lease Components |
| 26 | |
| 27 | - **ASC 842**: Lessees may elect (by class of underlying asset) to not separate lease and non-lease components — treat as single lease component. (ASC 842-10-15-42A) |
| 28 | - **IFRS 16**: Same practical expedient available to lessees (IFRS 16.15). Lessors must always separate components under IFRS 15. |

| 32 | ## Part 2: Lessee Classification — Dual Model (ASC 842) vs. Single Model (IFRS 16) |
| 33 | |
| 34 | ### Overview |
| 35 | |
| 36 | | Feature | ASC 842 (US GAAP) | IFRS 16 | UK FRS 102 (post-2026) | JGAAP (pre-ASBJ No.34) | JGAAP (post-ASBJ No.34 eff. Apr 2027) | CAS 21 | Ind AS 116 | |
| 37 | |---|---|---|---|---|---|---|---| |
| 38 | | Model | **Dual** (finance / operating) | **Single** (all leases → ROU + liability, unless exempt) | Broadly IFRS 16-aligned (periodic review amendments) | Dual model (old IAS 17-like) | **Single model** (IFRS 16-aligned) | Single model (IFRS 16-aligned) | Single model (identical to IFRS 16) | |
| 39 | | Operating lease on balance sheet? | Yes — ROU asset + lease liability, but P&L = straight-line total expense | No operating classification; all leases on balance sheet | Yes (post-amendment) | No (off-balance-sheet for operating leases) | Yes | Yes | Yes | |
| 40 | | Finance lease P&L pattern | Front-loaded (depreciation + interest) | Front-loaded | Front-loaded | Front-loaded | Front-loaded | Front-loaded | Front-loaded | |
| 41 | | Short-term exemption | ≤ 12 months at commencement | ≤ 12 months at commencement | Available | Available | Available | Available | Available | |
| 42 | | Low-value exemption | Underlying asset ≤ ~$5K when new | Underlying asset ≤ ~$5K when new (indicative) | Available | N/A | Available | Available (≤ ¥40K) | Available | |
| 43 | |
| 44 | ### ASC 842 Finance Lease Classification Criteria (842-20-25-2) |
| 45 | |
| 46 | A lessee classifies a lease as a **finance lease** if any one of the following criteria is met: |
| 47 | |
| 48 | 1. Transfer of ownership to lessee by or before lease end |
| 49 | 2. Purchase option the lessee is reasonably certain to exercise |
| 50 | 3. Lease term is for the **major part** of the remaining economic life (bright line: ≥ 75% is a common reference but not codified — judgment required) |
| 51 | 4. Present value of lease payments plus any residual value guarantee equals or exceeds **substantially all** of the fair value (bright line: ≥ 90% is a common reference — judgment required) |
| 52 | 5. Underlying asset is of such a **specialized nature** that it has no alternative use to the lessor at lease end |
| 53 | |
| 54 | If none of the above: **operating lease**. |
| 55 | |
| 56 | ### IFRS 16 Single-Model Lessee Treatment |
| 57 | |
| 58 | All leases (other than exempt short-term and low-value) are treated as **finance-type** on balance sheet: |
| 59 | - Recognize a **right-of-use (ROU) asset** an |
