IFRS 16 vs ASC 842: Key Differences in Lease Accounting

Both IFRS 16 (International) and ASC 842 (US GAAP) revolutionized lease accounting when they took effect in 2019, bringing billions in lease obligations onto balance sheets worldwide. While both standards share the same goal—improving transparency and comparability—they diverge in several critical areas.

This comprehensive guide compares IFRS 16 and ASC 842 side-by-side, highlighting key differences that impact multinational companies, auditors, and financial analysts.

International Standard IFRS 16
US GAAP Standard ASC 842
Effective Date Jan 1, 2019

Overview and Background

IFRS 16 (International Standard)

Issued by: International Accounting Standards Board (IASB)
Effective date: January 1, 2019
Applicable to: All entities reporting under IFRS globally

Key Principle: IFRS 16 uses a single lessee accounting model with no distinction between operating and finance leases for lessees. All leases go on the balance sheet (except short-term and low-value exemptions).

Adopted by: European Union, Australia, Singapore (SFRS 16), Malaysia (MFRS 16), Hong Kong, and 140+ jurisdictions worldwide.

ASC 842 (US GAAP Standard)

Issued by: Financial Accounting Standards Board (FASB)
Effective date: December 15, 2018 (public companies), 2019-2021 (private companies)
Applicable to: US entities and foreign companies reporting under US GAAP

Key Principle: ASC 842 maintains a dual lessee accounting model distinguishing between:

  • Finance Leases: Similar to capital leases under old ASC 840
  • Operating Leases: Different P&L presentation (single lease expense)
Both types appear on the balance sheet.

Adopted by: United States, foreign private issuers filing with SEC using US GAAP.

Quick Summary: IFRS 16 = one model for all leases. ASC 842 = two models (operating vs. finance). Both bring leases onto the balance sheet.

Side-by-Side Comparison Table

Aspect IFRS 16 ASC 842
Lessee Classification Single model (no classification) Dual model (operating vs. finance)
Balance Sheet Recognition ROU asset + Lease liability for all leases ROU asset + Lease liability for all leases
P&L Presentation Depreciation + Interest (separate line items) Operating: Single lease expense
Finance: Amortization + Interest
Expense Pattern Front-loaded (higher in early years) Operating: Straight-line
Finance: Front-loaded
Classification Tests None required for lessees 5 criteria (ownership transfer, purchase option, lease term, present value, specialized asset)
Short-Term Exemption ≤12 months, no purchase option ≤12 months
Low-Value Exemption Yes (~$5,000 USD when new) No (must apply short-term exemption instead)
Initial Direct Costs Capitalized in ROU asset Capitalized in ROU asset
Lease Modifications Remeasure using revised discount rate Different rules based on modification type
Sale-Leaseback Gain/loss based on IFRS 15 transfer of control Similar to IFRS 16 under ASU 2016-02
Lessor Accounting Substantially carried forward from IAS 17 Similar to IFRS 16, aligned with ASC 606 revenue
Statement of Cash Flows Principal: Financing
Interest: Operating or Financing (policy choice)		 Operating: All in operating
Finance: Principal in financing, interest in operating

Lease Classification: The Biggest Difference

IFRS 16: No Classification Required

Under IFRS 16, lessees do not classify leases. All leases receive the same accounting treatment:

  1. Recognize ROU asset and lease liability at commencement
  2. Depreciate ROU asset (usually straight-line)
  3. Calculate interest expense on lease liability using effective interest method
  4. Present depreciation and interest as separate line items in P&L

Simplicity: No need to evaluate classification criteria or apply judgment on lease type.

ASC 842: Operating vs. Finance Classification

Under ASC 842, lessees must classify each lease as either operating or finance based on 5 criteria:

Classification Criteria (ASC 842) Finance Lease if TRUE
1. Ownership transfer at end of lease term ✓ Finance
2. Purchase option reasonably certain to exercise ✓ Finance
3. Lease term is major part of asset's economic life (≥75% benchmark) ✓ Finance
4. PV of lease payments ≥ substantially all of asset's fair value (≥90% benchmark) ✓ Finance
5. Underlying asset is specialized with no alternative use to lessor ✓ Finance

If ANY of the 5 criteria are met → Finance Lease
If NONE of the criteria are met → Operating Lease

Important: The 75% and 90% thresholds are no longer bright lines under ASC 842 but remain commonly used benchmarks for evaluation.

Impact of Classification

Classification under ASC 842 affects P&L presentation and expense pattern:

Finance Lease (ASC 842)

P&L: Amortization expense + Interest expense (separate lines)

Expense Pattern: Front-loaded (same as IFRS 16)

Cash Flow: Principal in financing, interest in operating

Operating Lease (ASC 842)

P&L: Single lease expense (straight-line)

Expense Pattern: Straight-line (constant each period)

Cash Flow: All in operating activities

Expense Recognition Patterns

Numerical Example: 5-Year Office Lease

Lease Details:

  • Annual payment: $100,000
  • Lease term: 5 years
  • Discount rate: 6%
  • Initial lease liability (PV): $421,236

Assumptions:

  • Under ASC 842, the lease is classified as Operating Lease (fails all 5 criteria)
  • Under IFRS 16, no classification needed (single model)

Year 1 Expense Comparison

Standard Expense Components Total Year 1 Expense
IFRS 16 Depreciation: $84,247
Interest: $25,274		 $109,521
ASC 842 (Operating) Single Lease Expense: $100,000 $100,000
ASC 842 (Finance) Amortization: $84,247
Interest: $25,274		 $109,521

5-Year Total Expense Pattern

Year IFRS 16 ASC 842 Operating ASC 842 Finance
Year 1 $109,521 $100,000 $109,521
Year 2 $103,521 $100,000 $103,521
Year 3 $97,110 $100,000 $97,110
Year 4 $90,263 $100,000 $90,263
Year 5 $82,960 $100,000 $82,960
TOTAL $483,375 $500,000 $483,375
Key Insight: Under ASC 842 operating lease treatment, the total expense is higher ($500K vs. $483K) because the discount effect is not applied. IFRS 16 and ASC 842 finance leases produce identical results with front-loaded expenses.

Impact on Financial Ratios

EBITDA Impact

IFRS 16

Depreciation and interest are excluded from EBITDA.

Result: EBITDA increases compared to old operating lease treatment (where rent reduced EBITDA).

Example: A company with $10M in annual lease payments sees EBITDA increase by ~$10M.

ASC 842

Operating Lease: Single lease expense typically presented in operating expenses (reduces EBITDA)

Finance Lease: Amortization and interest excluded (increases EBITDA)

Classification matters: Operating leases may still reduce EBITDA depending on presentation.

Leverage Ratios (Debt-to-Equity, Debt-to-Assets)

Both IFRS 16 and ASC 842: Lease liabilities appear on the balance sheet, increasing total liabilities.

Impact: Debt-to-equity and debt-to-assets ratios increase for companies with significant operating leases (e.g., retailers, airlines, restaurants).

Return on Assets (ROA)

Both standards: ROU assets increase total assets.

Impact: ROA typically decreases due to higher asset base and (under IFRS 16) higher front-loaded expenses in early years.

Key Takeaway for Analysts

When comparing companies using IFRS 16 vs. ASC 842, pay attention to lease classification under ASC 842. Operating leases produce straight-line expenses, while IFRS 16 always uses front-loaded expenses.

When to Use IFRS 16 vs ASC 842

Use IFRS 16 if:

  • Your company reports under IFRS (international standard)
  • You're located in the EU, Singapore (SFRS 16), Malaysia (MFRS 16), Australia, or other IFRS jurisdictions
  • You're a subsidiary of an IFRS-reporting parent
  • You want simplified accounting (no classification testing)

Use ASC 842 if:

  • Your company reports under US GAAP
  • You're a US-based entity or foreign private issuer filing with the SEC
  • You're a subsidiary of a US parent company

Dual Reporting (IFRS and US GAAP)

Many multinational companies maintain dual reporting systems. Key challenges:

  • Different lease classifications under ASC 842
  • Different expense patterns for the same lease
  • Requires separate lease accounting systems or reconciliation processes

Case Studies

Case Study 1: International Retailer (IFRS 16)

Company: GlobalRetail Ltd (EU-based, 500+ stores)

Lease Portfolio: Retail store leases, average 10-year terms, $50M annual rent

Impact under IFRS 16:

  • Added ~$350M in ROU assets and lease liabilities to balance sheet
  • EBITDA increased by ~$50M (lease payments no longer reduce EBITDA)
  • Operating profit decreased in Year 1 due to front-loaded expense pattern
  • Debt-to-equity ratio increased from 0.8 to 1.4

Key Insight: Investors needed to adjust valuation models to account for higher EBITDA but also higher financial leverage.

Case Study 2: US Technology Company (ASC 842)

Company: TechCorp Inc (US GAAP, office and data center leases)

Lease Portfolio: 20 office locations, 5 data centers, $30M annual lease payments

Classification Analysis:

  • Office leases: Operating leases (5-year terms, 20% of building life)
  • Data center leases: Finance leases (15-year terms, specialized build-outs)

Impact under ASC 842:

  • Balance sheet: $210M ROU assets and lease liabilities recognized
  • P&L (Office leases): Straight-line lease expense = $20M/year
  • P&L (Data centers): Amortization $8M + Interest $2M = $10M Year 1
  • EBITDA: Increased by $10M (only data center leases excluded)

Key Insight: Mixed classification resulted in different expense patterns for economically similar leases, adding complexity for analysts.
