GENERAL FRAMEWORK

Understanding the foundational differences in standard-setting and philosophy is key to interpreting financial statements accurately.

Topic IFRS U.S. GAAP
Standard-Setting Bodies Issued by the International Accounting Standards Board (IASB). Issued by the Financial Accounting Standards Board (FASB).
Underlying Approach Principles-based: Provides broad frameworks requiring significant professional judgment. Rules-based: Offers detailed, prescriptive guidance for specific transactions.

Key Difference: This is the most fundamental difference. IFRS allows more flexibility but requires deeper judgment. U.S. GAAP reduces ambiguity but can lead to mechanical application.

INCOME STATEMENT

Key differences in revenue recognition and expense treatment impact profitability reporting.

Topic IFRS U.S. GAAP
Revenue Recognition Uses the converged 5-step model. "Probable" collection is generally interpreted as >50% likelihood. Same 5-step model, but "probable" may be interpreted more strictly (e.g., >75%), leading to delayed recognition in some cases.
Development Costs Capitalized if criteria (e.g., technical feasibility) are met. Treated as an intangible asset. Expensed as incurred, except for software development costs after technological feasibility.
Non-Recurring Items Discloses "significant" or "exceptional" items. Discontinued operations shown net of tax below continuing income. No "extraordinary items." Discontinued operations presented similarly.

Impact Analysis

IFRS companies may report higher profits and stronger balance sheets due to capitalization of development costs. Revenue timing differences are usually minor but can affect growth trends.

BALANCE SHEET

Differences in asset valuation and impairment rules affect reported equity and asset quality.

Topic IFRS U.S. GAAP
Inventory Valuation LIFO prohibited. Uses FIFO or weighted average. Measured at lower of cost or Net Realizable Value (NRV). LIFO permitted. Measured at lower of cost or "market" (replacement cost).
Reversal of Write-Downs Allowed if inventory value recovers (up to original cost). Prohibited. Write-downs are permanent.
Revaluation of PPE & Intangibles Permitted. Gains go to revaluation surplus in equity. Not allowed. Historical cost model only.
Impairment of Long-Lived Assets One-step test (carrying amount vs. recoverable amount). Reversals allowed (except goodwill). Two-step test. Reversals prohibited.
Goodwill
Not amortized under either standard. Tested annually for impairment.
Impairment losses cannot be reversed under both standards.
Deferred Taxes All deferred tax assets/liabilities classified as non-current. Netted by jurisdiction. Now aligned: also non-current and netted.

Analytical Implications

In inflation, U.S. GAAP LIFO users show lower profits and inventory values. IFRS companies can boost profits later via reversal of write-downs. Revaluation can inflate asset values on IFRS balance sheets.

CASH FLOW STATEMENT

Classification differences affect comparability of operating cash flow.

Topic IFRS U.S. GAAP
Interest Paid Can be classified as Operating or Financing (policy must be consistent). Mandatory Operating activity.
Interest Received Can be Operating or Investing. Mandatory Operating.
Dividends Paid Can be Operating or Financing. Mandatory Financing.
Dividends Received Can be Operating or Investing. Mandatory Operating.
Bank Overdrafts Can be part of cash and cash equivalents if part of cash management. Treated as short-term borrowing (liability).

Analyst Adjustment: These differences make CFO less comparable. Analysts often reclassify interest/dividends to ensure consistency. Overdraft treatment affects reported cash balances.

5

OTHER KEY AREAS

Additional differences that impact financial analysis and comparability.

Topic IFRS U.S. GAAP
Lease Accounting (Lessee) Single model: All leases (except short-term) recognized on balance sheet. Expense is split into interest and amortization. Dual model: Finance and operating leases treated differently. Operating leases show straight-line total expense.
Pension Accounting Remeasurements (gains/losses) go directly to Other Comprehensive Income (OCI). Gains/losses go to OCI but may be amortized into income via the "corridor" method.

Summary Impact

Lease differences affect income statement expense patterns. Pension differences can cause smoother reported pension expense under U.S. GAAP due to amortization.

Key Takeaways for Analysts

Comparability Challenges

  • Cash flow classifications vary significantly
  • Asset valuation methods differ
  • Revenue recognition timing can vary
  • Impairment reversals create asymmetry

Analyst Adjustments Needed

  • Reclassify cash flow items for consistency
  • Adjust for development cost capitalization
  • Consider LIFO inventory effects
  • Normalize for revaluation gains

90TH PERCENTILE MASTERY: KEY CONCEPTS & EXAM TIPS

Exam Weight & Focus Areas

This reading typically accounts for 2-4% of Level I exam weight. Focus on:

  • LIFO prohibition under IFRS - This is THE most tested difference
  • Development cost capitalization - IFRS allows, GAAP expenses
  • Impairment reversals - IFRS allows (except goodwill), GAAP prohibits
  • Cash flow classification differences - Interest, dividends treatment
  • Principles vs. rules-based - Fundamental philosophical difference

Complete Differences Table

Category Topic IFRS U.S. GAAP Impact
INVENTORY Valuation Methods FIFO, Weighted Avg ONLY FIFO, LIFO, Weighted Avg LIFO users show lower profit in inflation
Measurement Lower of cost or NRV Lower of cost or market NRV typically higher than "market"
Write-down Reversals ALLOWED PROHIBITED IFRS can boost future profits
LONG-LIVED ASSETS PPE Revaluation PERMITTED NOT ALLOWED IFRS can inflate asset values
Impairment Test One-step (carrying vs. recoverable) Two-step test IFRS simpler, earlier impairment
Impairment Reversals ALLOWED (except goodwill) PROHIBITED IFRS more volatile asset values
INTANGIBLES Development Costs CAPITALIZED if criteria met EXPENSED IFRS higher profit & assets
Research Costs BOTH expense as incurred No difference
CASH FLOW Interest Paid Operating OR Financing Operating (mandatory) IFRS can boost CFO
Dividends Paid Operating OR Financing Financing (mandatory) IFRS flexibility reduces comparability
Interest Received Operating OR Investing Operating (mandatory) Classification affects CFO
Dividends Received Operating OR Investing Operating (mandatory) IFRS has more flexibility
INCOME STATEMENT Extraordinary Items NOT segregated Prohibited (eliminated 2015) Now converged
Revenue Recognition BOTH use 5-step model (ASC 606 / IFRS 15) Converged since 2018
LEASES Lessee Accounting Single model (all on B/S) Dual model (finance vs. operating) Expense pattern differs
TAXES Deferred Tax Classification BOTH classify as non-current Now converged

Convergence Status Update

Areas of Convergence (Fully Aligned)
  • Revenue Recognition: Both use IFRS 15 / ASC 606 (5-step model) since 2018
  • Deferred Taxes: Both classify as non-current on balance sheet
  • Segment Reporting: Similar requirements (IFRS 8 / ASC 280)
  • Fair Value Measurement: Aligned framework (IFRS 13 / ASC 820)
  • Discontinued Operations: Similar presentation requirements
Partial Convergence (Some Differences Remain)
  • Lease Accounting: Both require capitalization, but GAAP has dual model
  • Financial Instruments: Similar impairment approach (expected credit loss), minor differences
  • Insurance Contracts: Convergence in progress (IFRS 17 implemented 2023)
Key Persistent Differences (Unlikely to Converge)
  • LIFO: IFRS prohibition vs. GAAP allowance (for tax reasons in U.S.)
  • Development Costs: IFRS capitalization vs. GAAP expensing
  • Impairment Reversals: IFRS allows vs. GAAP prohibits
  • Revaluation Model: IFRS option vs. GAAP historical cost only
  • Principles vs. Rules: Fundamental philosophical difference remains

COMMON EXAM TRAPS & MISTAKES

Trap #1: Assuming Convergence

Mistake: Thinking all standards have converged post-2018

Reality: While revenue recognition converged, major differences persist in inventory (LIFO), development costs, and reversals. Don't assume similarity!

Trap #2: Reversal Applicability

Mistake: Thinking IFRS allows ALL impairment reversals

Reality: IFRS allows reversals for PPE and inventory, but NOT for goodwill. Goodwill impairment is permanent under BOTH standards.

Trap #3: Cash Flow Comparability

Mistake: Directly comparing CFO between IFRS and GAAP companies

Reality: IFRS flexibility in classifying interest/dividends means CFO may not be comparable. Analysts must reclassify for apples-to-apples comparison.

Trap #4: Development vs. Research

Mistake: Thinking IFRS capitalizes ALL R&D

Reality: IFRS capitalizes DEVELOPMENT costs only (after technical feasibility). Research costs are ALWAYS expensed under both standards.

COMMON PITFALLS

LIFO Prohibition (Most Tested): IFRS prohibits LIFO; U.S. GAAP allows it. During rising prices, LIFO results in higher COGS, lower ending inventory, and lower net income compared to FIFO. This is the #1 tested IFRS/GAAP difference on the exam.

Development Cost Capitalization: IFRS requires capitalization of development costs (after technical feasibility is achieved), while U.S. GAAP expenses all R&D as incurred. Both expense research costs. Exception: Software development costs can be capitalized under GAAP after technological feasibility.

Impairment Reversals: IFRS allows reversal of impairments (except goodwill) if recoverable amount increases, limited to original carrying value. U.S. GAAP prohibits all impairment reversals. Neither standard allows reversal of goodwill impairment.

Cash Flow Classification Flexibility: IFRS allows flexibility in classifying interest and dividends (operating, investing, or financing depending on the item). U.S. GAAP mandates: interest paid/received and dividends received = operating; dividends paid = financing. This can significantly affect CFO comparability.

PPE Revaluation: IFRS allows (but doesn't require) revaluation of PPE to fair value, with gains going to OCI (revaluation surplus) and losses to income statement. U.S. GAAP prohibits PPE revaluation entirely (historical cost model only). Must apply consistently to entire asset class.

Principles vs. Rules-Based: IFRS is principles-based (more judgment required), while U.S. GAAP is rules-based (more detailed guidance). This fundamental difference affects all financial reporting areas and leads to potential comparability issues.

Inventory Write-Down Reversals: IFRS allows reversal of inventory write-downs if circumstances change (NRV increases), limited to original cost. U.S. GAAP prohibits inventory write-down reversals—they are permanent.

Convergence Status: Revenue recognition (IFRS 15 / ASC 606) is FULLY converged using identical 5-step model. Other converged areas: fair value measurement, segment reporting. Major divergences remain: LIFO, development costs, impairment reversals, PPE revaluation.

Financial Statement Presentation: IFRS requires minimum line items but allows flexibility; U.S. GAAP has more prescriptive formatting rules. IFRS uses "statement of financial position" (vs. "balance sheet"), and extraordinary items are prohibited under IFRS but allowed (rarely) under GAAP.
