4.2 IAS 36 Impairment of Assets — Principles and Testing

4.2 IAS 36 Impairment of Assets — Principles and Testing

Financial statements must present a realistic view of an entity's asset base. Under historical cost accounting and standard depreciation schedules, carrying amounts could easily exceed the true economic value that an asset can generate if commercial circumstances deteriorate. IAS 36 Impairment of Assets prevents balance sheet overstatement by establishing rigorous rules to identify, measure, and account for asset impairments. In the ACCA Financial Reporting (FR) exam, questions frequently test candidates on external versus internal impairment indicators, the precise calculation of Recoverable Amount, mandatory cash flow exclusions in Value in Use (VIU), and the split accounting treatment for revalued assets.

1. Scope and the Core Principle of IAS 36

The Core Principle (IAS 36.1)

"An asset is impaired when its carrying amount exceeds its recoverable amount."

If the carrying amount of an asset on the Statement of Financial Position exceeds the amount to be recovered through its continued use or eventual sale, the asset is overstated. IAS 36 mandates that the asset must be written down to its recoverable amount, and an impairment loss must be recognized immediately.

Impairment Loss = Carrying Amount - Recoverable Amount

Scope of IAS 36

IAS 36 applies to non-current assets across several standards, including:

• Property, plant and equipment (IAS 16)
• Intangible assets (IAS 38)
• Right-of-use assets (IFRS 16)
• Investment property carried under the cost model (IAS 40)
• Goodwill acquired in a business combination (IFRS 3)

Excluded Assets (Governed by their own specific impairment rules):

• Inventories (IAS 2 — lower of cost and net realisable value)
• Deferred tax assets (IAS 12)
• Financial assets within the scope of IFRS 9 (expected credit loss model)
• Investment property measured at fair value (IAS 40)
• Biological assets measured at fair value less costs to sell (IAS 41)
• Non-current assets classified as held for sale (IFRS 5)

2. When to Test: Mandatory Annual vs. Indicator-Based Testing

Under IAS 36.9, an entity must assess at the end of each reporting period whether there is any indication that an asset may be impaired. If any such indication exists, the entity must estimate the recoverable amount of the asset.

                         IMPAIRMENT TESTING REGIME
                                     |
        +----------------------------+----------------------------+
        |                                                         |
  INDICATOR-BASED TESTING                               MANDATORY ANNUAL TESTING
  * Standard PPE (IAS 16)                               * Goodwill acquired in business combination
  * Finite-life intangibles (IAS 38)                    * Intangible assets with INDEFINITE useful life
  * Right-of-use assets (IFRS 16)                       * Intangible assets NOT YET AVAILABLE FOR USE
  * Test ONLY if indicators present                     * Test EVERY YEAR, regardless of indicators

The Three Exceptions: Mandatory Annual Impairment Testing (IAS 36.10)

Irrespective of whether any impairment indicators exist, an entity must test the following three asset categories for impairment annually:

1. Goodwill acquired in a business combination.
2. Intangible assets with an indefinite useful life (e.g., perpetual operating licences).
3. Intangible assets not yet available for use (e.g., capitalised development projects in progress).

Timing of Annual Test: The annual test may be conducted at any time during the financial year, provided it is performed at the same time each year. Different assets may be tested at different times.

Impairment Indicators (IAS 36.12)

For all other assets, recoverable amount is estimated only if there is an indication of impairment. Indicators are divided into external and internal sources:

3. Determining Recoverable Amount: FVLCOD vs. Value in Use

Under IAS 36.18, the Recoverable Amount of an asset is formally defined as:

"The HIGHER of an asset's Fair Value Less Costs of Disposal (FVLCOD) and its Value in Use (VIU)."

Recoverable Amount = Maximum of (Fair Value Less Costs of Disposal, Value in Use)

                       RECOVERABLE AMOUNT DETERMINATION
                                      |
                      +---------------+---------------+
                      |                               |
               FVLCOD (Sale)                    VIU (Continued Use)
         Fair Value less disposal costs     Present value of future cash flows
                      |                               |
                      +---------------+---------------+
                                      |
                                      v
                         HIGHER OF THE TWO METRICS
                                      |
                                      v
                              RECOVERABLE AMOUNT
                                      |
                                      v
               Compare with CARRYING AMOUNT: If Carrying Amount >
                 Recoverable Amount -> RECOGNIZE IMPAIRMENT LOSS

Rational Economic Rationale: A rational entity will recover value from an asset through whichever route yields the greatest return: either by selling it immediately (FVLCOD) or by continuing to deploy it in production (VIU). Therefore, the recoverable amount is always the higher of the two.

• Exam Shortcut: If either FVLCOD or VIU exceeds the asset's carrying amount, the asset is not impaired. The entity is not required to calculate the other amount (IAS 36.19).

Fair Value Less Costs of Disposal (FVLCOD)

• Fair Value: The price that would be received to sell an asset in an orderly transaction between market participants at the measurement date under IFRS 13 Fair Value Measurement.
• Costs of Disposal: Incremental costs directly attributable to the disposal of an asset, excluding finance costs and income tax expense.
  • Allowable Costs of Disposal: Direct legal fees, stamp duty and transaction taxes, direct dismantling and removal costs, and direct marketing/auction commissions.
  • Excluded Costs: Redundancy payments to staff terminated after the asset is sold, or corporate relocation costs (these relate to ongoing business reorganisation, not the sale of the asset itself).

4. Value in Use (VIU) — Detailed Cash Flow Modeling Rules

Value in Use (VIU) is the present value of estimated future cash flows expected to arise from the continuing use of an asset and from its disposal at the end of its useful life (IAS 36.30).

Mandatory Cash Flow Rules & Strict Exclusions (IAS 36.33–50)

Cash flow projections must be based on reasonable and supportable assumptions reflecting management's best estimate over a maximum forecast period of five years (unless a longer period can be justified).

Candidates must master the strict rules governing what can and cannot be included in VIU cash flows:

  VALUE IN USE (VIU) CASH FLOW RULES:
  ===============================================================================
  INCLUDED CASH FLOWS:                    STRICTLY EXCLUDED CASH FLOWS (IAS 36.44-50):
  ------------------------------------    -------------------------------------------
  * Inflows from continuing operations    * Cash flows from future uncommitted restructurings
  * Outflows to generate inflows          * Future capex enhancing asset performance
  * Day-to-day servicing & maintenance    * Financing cash flows (interest / principal)
  * Net disposal cash flow at end of life * Income tax receipts or payments (pre-tax basis)
  ===============================================================================

1. Future Restructurings Not Yet Committed: Projections must exclude estimated future cash inflows or outflows expected to arise from a future restructuring to which the entity is not yet committed under IAS 37.
2. Capital Expenditure Enhancing Asset Performance: Projections must exclude estimated future cash flows expected to arise from improving or enhancing the asset's performance. The asset must be valued in its current physical condition. (Only routine maintenance capex necessary to maintain existing operational capacity is included).
3. Financing Cash Flows: Projections must exclude cash inflows or outflows from financing activities (e.g., loan interest payments or debt repayments). The time value of money is already accounted for in the discount rate.
4. Income Taxes: Projections must exclude income tax receipts or payments. VIU is computed on a pre-tax basis.

The Discount Rate (IAS 36.55)

The discount rate must be a pre-tax rate that reflects current market assessments of:

1. The time value of money; and
2. The risks specific to the asset for which the future cash flow estimates have not been adjusted. In practice, this is derived from the entity's Weighted Average Cost of Capital (WACC), adjusted for asset-specific and country risk factors.

5. Measuring and Recognizing an Impairment Loss

When carrying amount exceeds recoverable amount, the carrying amount must be reduced to the recoverable amount. The accounting treatment depends on the measurement model used for the asset:

Case A: Asset Carried at Historical Cost

For assets accounted for under the cost model (e.g., standard plant and machinery):

• The entire impairment loss is recognized immediately as an expense in the Statement of Profit or Loss.
• Debit: Impairment Loss (Profit or Loss — Operating Expense)
• Credit: Accumulated Impairment / PPE Carrying Amount (Statement of Financial Position)

Case B: Asset Carried under the Revaluation Model (IAS 16 / IAS 38)

Under IAS 36.60, if an asset has been previously revalued upward with a balance in equity:

• The impairment loss is treated as a revaluation decrease:
  1. Debit: Other Comprehensive Income (eliminates existing Revaluation Surplus in equity for that specific asset).
  2. Debit: Profit or Loss (any excess impairment loss exceeding the existing revaluation surplus balance is charged to profit or loss).
  3. Credit: Asset Gross Valuation / Carrying Amount (Statement of Financial Position).

Subsequent Depreciation after Impairment

Once an impairment loss is recognized, the depreciation (or amortisation) charge for future periods must be adjusted to allocate the revised carrying amount (less any revised residual value) systematically over its remaining useful life on a prospective basis (IAS 36.63).

6. Comprehensive Worked Example: Impairment of Individual Assets

Scenario Details

Titan Heavy Industries owns two specialized production units at 31 December 20X5:

Unit Alpha (Cost Model):

• Carrying amount at 31 December 20X5 before impairment review: $1,200,000 (Cost $1,800,000, Accumulated Depreciation $600,000; remaining useful life 6 years, straight-line, zero residual value).
• Due to new environmental emissions legislation, Unit Alpha's product demand has fallen. Titan conducts an impairment review:
  • Fair Value is estimated at $900,000; directly attributable dismantling and transport costs to complete the disposal are $40,000.
  • Management prepares 5-year cash flow forecasts for Value in Use. Future net annual operational cash inflows from current operations are $210,000 per year for 6 years.
  • The forecast also includes an expected annual cash savings inflow of $50,000 from a planned automated technological upgrade that management hopes to install in 20X7 (costing $150,000 to purchase).
  • Finance costs of $25,000 per year on a dedicated bank loan are included in the draft forecast.
  • Appropriate pre-tax discount rate is 10%. (The 6-year 10% annuity factor is 4.3553; present value of $1 in 6 years at 10% is 0.5645).

Unit Beta (Revaluation Model under IAS 16):

• Freehold industrial depot carried at a revalued amount of $850,000 at 31 December 20X5. An existing credit balance of $120,000 resides in the Revaluation Surplus in equity relating to prior revaluations of this specific depot.
• Due to severe local ground subsidence, an impairment review is triggered:
  • Fair Value less costs of disposal is appraised at $620,000.
  • Value in Use is calculated at $660,000.

Step 1: Determine Recoverable Amount for Unit Alpha

1. Fair Value Less Costs of Disposal (FVLCOD):

FVLCOD = Fair Value ($900,000) - Disposal Costs ($40,000) = $860,000

1. Adjust Cash Flows for Value in Use (VIU):

• Under IAS 36.44, cash flows from future uncommitted capital enhancements (the $150,000 upgrade outlay and $50,000 annual savings) must be excluded.
• Under IAS 36.50, financing cash flows (the $25,000 annual loan interest) must be excluded.
• Valid unadjusted annual operational cash flow = $210,000 per year for 6 years.

VIU = Annual Cash Flow ($210,000) * Annuity Factor (4.3553) = $914,613

1. Recoverable Amount of Unit Alpha:

Recoverable Amount = Maximum of (FVLCOD $860,000, VIU $914,613) = $914,613

1. Impairment Loss for Unit Alpha:

Impairment Loss = Carrying Amount ($1,200,000) - Recoverable Amount ($914,613) = $285,387

Journal Entry for Unit Alpha:

Dr Impairment Loss (Profit or Loss)          $285,387
   Cr Unit Alpha (Carrying Amount)                     $285,387

• Revised carrying amount at 31 December 20X5 = $914,613.
• Revised prospective annual depreciation for 20X6: $914,613 / 6 = $152,436 per year.

Step 2: Determine Recoverable Amount and Impairment for Unit Beta

1. Recoverable Amount of Unit Beta:

Recoverable Amount = Maximum of (FVLCOD $620,000, VIU $660,000) = $660,000

1. Total Impairment Loss on Unit Beta:

Total Impairment Loss = Carrying Amount ($850,000) - Recoverable Amount ($660,000) = $190,000

1. Accounting Treatment for Revalued Asset:

• Existing Revaluation Surplus for Unit Beta = $120,000.
• Under IAS 36.60, the impairment loss is charged first to OCI against the revaluation surplus ($120,000), and the excess ($190,000 - $120,000 = $70,000) is charged to Profit or Loss. Journal Entry for Unit Beta:

Dr Revaluation Surplus (OCI / Equity)       $120,000
Dr Impairment Loss (Profit or Loss)          $70,000
   Cr Unit Beta (Revalued Carrying Amount)             $190,000

• Revised carrying amount of Unit Beta at 31 December 20X5 = $660,000.
• Closing balance in Revaluation Surplus in equity for Unit Beta = $0.

7. Common Exam Traps & ACCA Examiner Tips

[!WARNING] ACCA Examiner Trap 1: The "Lower Of" Misconception Candidates frequently write that "recoverable amount is the lower of fair value less costs to sell and value in use." This is a critical error! Recoverable amount is the HIGHER of the two. The asset is then written down to the lower of carrying amount and recoverable amount.

[!WARNING] ACCA Examiner Trap 2: The Cash Flow Enhancements Trap Exam questions regularly include planned capital expenditure that will expand factory capacity and increase future sales. When calculating VIU, candidates must exclude all cash flows related to uncommitted enhancements. The asset must be valued strictly in its current physical state.

[!TIP] ACCA Examiner Tip: The Tax and Interest Fallacy VIU is a pre-tax operating cash flow calculation. Candidates must strip out tax payments and debt interest payments from draft management cash flow schedules before discounting at the pre-tax discount rate.

[!TIP] ACCA Examiner Tip: Revaluation Surplus Offsetting Trap If Asset A suffers an impairment deficit, an entity cannot offset it against a revaluation surplus belonging to Asset B. Revaluation surpluses are strictly asset-specific.
