Model Assumptions
- Payments at end of each period (ordinary annuity)
- Discount rate is lessee's incremental borrowing rate (or implicit rate if known)
- No variable lease payments based on index or rate
- No residual value guarantees included in PV calculation
- IDC, prepaid payments, and incentives are one-time adjustments to ROU asset
- ROU asset amortized straight-line over lease term (or useful life if ownership transfers/purchase option certain)
- ASC 842 (US GAAP) classification; 75%/90% are common guideposts, not statutory bright lines
- Lessee perspective only; lessor accounting out of scope
- For educational purposes only. Not financial advice. Market conventions simplified.
Understanding ASC 842 Lease Accounting
What Changed with ASC 842?
Prior to ASC 842, operating leases were kept off the balance sheet, meaning companies could have significant lease obligations without reporting them as liabilities. The top 1,000 U.S. companies had approximately $1 trillion in off-balance-sheet operating lease liabilities. ASC 842, effective since 2019, requires all leases over 12 months to be recognized on the balance sheet as a right-of-use (ROU) asset and a corresponding lease liability.
Finance vs Operating Leases
Finance Lease
Interest + Amortization
Front-loaded expense pattern. Interest expense on declining liability plus straight-line amortization of ROU asset. Principal payments classified as financing activities.
Operating Lease
Single Straight-Line Expense
Level expense each period. Total cost (payments + IDC - incentives) spread evenly over the lease term. All payments in operating activities.
The Five Classification Criteria
Under ASC 842, a lease is classified as a finance lease if it meets any one of five criteria:
- Transfer of ownership at the end of the lease term
- Purchase option that the lessee is reasonably certain to exercise
- Lease term is 75% or more of the remaining economic life of the asset
- Present value of lease payments is 90% or more of the asset's fair value
- Specialized asset with no alternative use to the lessor
The 75% and 90% thresholds are practical guideposts commonly used in practice, consistent with the guidance in ASC 842.
