14.3 Impairment Testing & Accounting for Individual Assets

Key Takeaways

  • An individual asset is impaired when its carrying amount (CACA) exceeds its recoverable amount (RARA), resulting in an impairment loss equal to CA−RACA - RA.

  • For assets carried under the historical cost model (IAS 16 / IAS 38), the impairment loss is recognized immediately in profit or loss as an expense, credited against accumulated impairment losses.

  • For assets carried under the revaluation model (IAS 16 / IAS 38), the impairment loss is treated as a revaluation decrease: recognized first in Other Comprehensive Income (OCI) to eliminate any existing revaluation surplus for that specific asset, with any excess recognized in profit or loss.

  • Following an impairment write-down, future depreciation or amortization charges must be recalculated prospectively to systematically allocate the revised carrying amount (less residual value) over the asset's remaining useful life.

  • Under IAS 16.61 and IAS 38.104, conducting an impairment test provides objective evidence requiring a mandatory review of the asset's remaining useful life, depreciation method, and residual value, even if no impairment loss is ultimately recognized.

14.3 Impairment Testing & Accounting for Individual Assets

Core Principle: When an asset's carrying amount exceeds its recoverable amount, an impairment loss must be recognized immediately. Under the cost model, the loss is charged directly to profit or loss. Under the revaluation model, the loss is recognized in other comprehensive income to the extent of any existing revaluation surplus for that asset, with any excess recognized in profit or loss.

Once Recoverable Amount (RARA) has been determined—as the higher of Fair Value Less Costs of Disposal (FVLCD) and Value in Use (VIU)—the final phase of the IAS 36 individual asset framework is testing and accounting recognition. Under paragraph 59 of IAS 36:

If, and only if, the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset shall be reduced to its recoverable amount. That reduction is an impairment loss.


1. Impairment Testing Formulation & Recognition Criteria

The fundamental impairment equation for an individual asset is:

Impairment Loss=max⁡(0, Carrying Amount−Recoverable Amount)\text{Impairment Loss} = \max\Big(0,\, \text{Carrying Amount} - \text{Recoverable Amount}\Big)
  • If RA≥CARA \ge CA: The asset is not impaired. No accounting write-down is recorded. The asset continues to be carried at its existing book value, subject to standard depreciation.
  • If CA>RACA > RA: An impairment loss exists. The asset's carrying amount must be written down immediately to its recoverable amount.
  • Asset Balance Floor: An individual asset's carrying amount can never be reduced below zero, nor below the higher of its FVLCD and VIU if determinable (a critical rule for Cash-Generating Units explored in Chapter 15).

2. Accounting Treatment: Cost Model vs Revaluation Model

The double-entry mechanics for an impairment loss depend strictly on whether the underlying asset is carried under the historical cost model or the revaluation model of IAS 16 or IAS 38.

Pathway A: Assets Carried at Historical Cost (IAS 36.60)

For operational assets carried under the cost model (historical cost less accumulated depreciation and accumulated impairment losses):

  • The impairment loss is recognized immediately in Profit or Loss as an operating expense.
  • The credit entry is recorded either directly to the asset account or to a dedicated contra-asset account titled Accumulated Impairment Losses.
General Journal Entry (Cost Model):Dr Impairment Loss (Profit or Loss)[Full Loss Amount]Cr Accumulated Impairment Losses (Contra-Asset)[Full Loss Amount]\begin{aligned} \textbf{General Journal Entry (Cost Model):} & \\ \quad \text{Dr Impairment Loss (Profit or Loss)} & \quad [\text{Full Loss Amount}] \\ \quad \quad \text{Cr Accumulated Impairment Losses (Contra-Asset)} & \quad [\text{Full Loss Amount}] \end{aligned}

Pathway B: Assets Carried at Revalued Amounts (IAS 36.60)

Under paragraph 60 of IAS 36, if the asset is carried at a revalued amount in accordance with another standard (such as the revaluation model in IAS 16 or IAS 38):

An impairment loss on a revalued asset is recognized in other comprehensive income to the extent that the impairment loss does not exceed the amount in the revaluation surplus for that same asset. Such an impairment loss on a revalued asset reduces the revaluation surplus for that asset. To the extent that the impairment loss exceeds the revaluation surplus for that same asset, the excess is recognized in profit or loss.

The Two-Step Allocation for Revalued Assets:

  1. Step 1 (Offset OCI Surplus): Debit Revaluation Surplus (Other Comprehensive Income) up to the credit balance sitting in equity for that specific asset. This reverses previously recognized revaluation gains without affecting current-year profit or loss.
  2. Step 2 (Excess to Profit or Loss): Debit Impairment Loss (Profit or Loss) for any remaining unabsorbed impairment loss.
  3. Step 3 (Reduce Asset): Credit the Asset Carrying Amount (or Accumulated Impairment Losses) for the total impairment loss.
General Journal Entry (Revalued Asset with Existing Surplus):Dr Revaluation Surplus (OCI)[Up to asset’s existing surplus]Dr Impairment Loss (Profit or Loss)[Excess beyond existing surplus]Cr Asset (or Accumulated Impairment)[Total Impairment Loss]\begin{aligned} \textbf{General Journal Entry (Revalued Asset with Existing Surplus):} & \\ \quad \text{Dr Revaluation Surplus (OCI)} & \quad [\text{Up to asset's existing surplus}] \\ \quad \text{Dr Impairment Loss (Profit or Loss)} & \quad [\text{Excess beyond existing surplus}] \\ \quad \quad \text{Cr Asset (or Accumulated Impairment)} & \quad [\text{Total Impairment Loss}] \end{aligned}

Strict Anti-Netting Rule: An entity cannot cross-subsidize revaluation surpluses between different assets! If Building A has an existing revaluation surplus in equity of $400,000, and Building B experiences an impairment loss of $250,000 with zero revaluation surplus, the entire $250,000 loss on Building B must be recognized in Profit or Loss. Management is strictly prohibited from offsetting Building B's impairment against Building A's revaluation surplus.

3. Consequential Depreciation & Revision of Accounting Estimates (IAS 36.63-64)

Recognizing an impairment loss alters the economic carrying amount of the asset. Paragraph 63 of IAS 36 establishes the mandatory subsequent depreciation rule:

After the recognition of an impairment loss, the depreciation (amortisation) charge for the asset shall be adjusted in future periods to allocate the asset's revised carrying amount, less its residual value (if any), on a systematic basis over its remaining useful life.

The Prospective Recalculation Formula

Depreciation is never adjusted retrospectively. The adjustment is accounted for strictly prospectively as a change in accounting estimate under IAS 8 / AASB 108 Accounting Policies, Changes in Accounting Estimates and Errors:

Revised Annual Depreciation=Revised Carrying Amount (Recoverable Amount)−Revised Residual ValueRevised Remaining Useful Life\text{Revised Annual Depreciation} = \frac{\text{Revised Carrying Amount (Recoverable Amount)} - \text{Revised Residual Value}}{\text{Revised Remaining Useful Life}}

Mandatory Review of Useful Life, Residual Value, and Depreciation Method (IAS 36.64)

Paragraph 64 of IAS 36 contains a critical procedural requirement often tested in exam scenario questions:

If an indication of impairment exists, the remaining useful life, the depreciation (amortisation) method or the residual value for the asset shall be reviewed and adjusted in accordance with the standard applicable to the asset (e.g. IAS 16 or IAS 38), even if no impairment loss is recognised for the asset.

Why does IAS 36 mandate this review even when no impairment loss is recorded? Because the external or internal event that triggered the impairment test (e.g. technological change, physical wear, or economic decline) signals that the operational utility of the asset has changed. Even if current high market prices (FVLCD) protect the asset from an impairment write-down, its remaining useful life may have shortened from 10 years to 4 years, requiring higher annual depreciation in subsequent periods.


4. Comprehensive Worked Example 1: Operational Asset Under the Cost Model

Fact Pattern

On 1 July 2023, Kestrel Mining Ltd purchased a specialized autonomous ore-hauler for $1,200,000. At acquisition, Kestrel estimated:

  • Useful life: 10 years
  • Residual value: Nil
  • Depreciation method: Straight-line ($120,000 per year)
  • Measurement model: Historical Cost Model under IAS 16

On 30 June 2026 (after 3 full years of operation), an aggressive new zero-emissions mining mandate is introduced by state regulators. The ore-hauler is an older diesel-powered model, triggering an indicator of impairment.

At 30 June 2026, management estimates the following recoverable amount figures:

  • Fair Value Less Costs of Disposal (FVLCD): $580,000
  • Value in Use (VIU): $620,000

Following the impairment review, Kestrel's fleet engineers determine that due to regulatory restrictions, the hauler's remaining useful life is now 5 years (instead of the original remaining 7 years), and its revised residual value is $20,000.

Step 1: Record Standard Annual Depreciation for FY2026 (Year Ended 30 June 2026)

Prior to performing the impairment test at reporting date, standard depreciation for the third operational year must be recognized:

5. Comprehensive Worked Example 2: Operational Asset Under the Revaluation Model

Fact Pattern

On 1 July 2022, Meridian Properties Ltd acquired a commercial administrative building for $5,000,000. Key initial terms:

  • Useful life: 50 years
  • Residual value: Nil
  • Depreciation method: Straight-line ($100,000 per year)
  • Measurement model: Revaluation Model under IAS 16 (revaluations performed every 2 years)

Prior Revaluation History at 30 June 2024

On 30 June 2024 (2 years after purchase), an independent valuation assessed the building's fair value at $5,400,000.

  • Carrying amount prior to revaluation: $5,000,000 - (2 years ×\times $100,000) = $4,800,000.
  • Revaluation Surplus recognized in OCI: $5,400,000 - $4,800,000 = $600,000.
  • Remaining useful life at 30 June 2024: 48 years.
  • Revised annual depreciation: $5,400,000 / 48 years = $112,500 per year.
  • Meridian does not make annual piecemeal transfers of revaluation surplus to retained earnings.

Current Year Impairment Event at 30 June 2026

On 30 June 2026 (2 years after the revaluation), severe structural foundation cracking is discovered following seismic tremors (internal indicator under IAS 36.12(e)).

Prior to impairment testing, standard depreciation for the 2 years ended 30 June 2026 has been recognized (2 ×\times $112,500 = $225,000 accumulated depreciation since revaluation).

An independent engineering and appraisal firm calculates:

  • Fair Value Less Costs of Disposal (FVLCD): $4,300,000
  • Value in Use (VIU): $4,450,000

Structural engineers advise that while the building remains operational after reinforcing beams are installed, its remaining useful life is drastically reduced to 25 years from 30 June 2026. Residual value remains nil.


Accounting Calculations & Journal Entries

Step 1: Determine Carrying Amount at 30 June 2026 Prior to Impairment

Revalued Carrying Amount at 30 June 2024=$5,400,000Less Depreciation FY2025 & FY2026 (2 years ×$112,500)=($225,000)Carrying Amount at 30 June 2026 (before impairment)=$5,175,000\begin{aligned} \text{Revalued Carrying Amount at 30 June 2024} & = \$5,400,000 \\ \text{Less Depreciation FY2025 \& FY2026 (2 years } \times \$112,500) & = (\$225,000) \\ \hline \mathbf{\text{Carrying Amount at 30 June 2026 (before impairment)}} & = \mathbf{\$5,175,000} \end{aligned}

Status of Equity: The Revaluation Surplus sitting in equity for this specific building stands at $600,000.

Step 2: Determine Recoverable Amount & Total Impairment Loss

Recoverable Amount=max⁡(FVLCD, VIU)=max⁡($4,300,000, $4,450,000)=$4,450,000Total Impairment Loss=Carrying Amount−Recoverable Amount=$5,175,000−$4,450,000=$725,000\begin{aligned} \text{Recoverable Amount} & = \max(\text{FVLCD},\, \text{VIU}) = \max(\$4,300,000,\, \$4,450,000) = \mathbf{\$4,450,000} \\ \text{Total Impairment Loss} & = \text{Carrying Amount} - \text{Recoverable Amount} \\ & = \$5,175,000 - \$4,450,000 = \mathbf{\$725,000} \end{aligned}

Step 3: Allocate Total Impairment Loss Under IAS 36.60

Applying the two-tier revaluation allocation rules:

  1. Allocate to Revaluation Surplus (OCI): The loss is recognized in Other Comprehensive Income to the extent of the revaluation surplus for this specific asset:
Absorption by Revaluation Surplus=$600,000\text{Absorption by Revaluation Surplus} = \mathbf{\$600,000}

This reduces the building's revaluation surplus balance in equity from $600,000 to $0. 2. Allocate Excess to Profit or Loss: The remaining unabsorbed impairment loss is recognized immediately in Profit or Loss:

Excess Charged to P/L=$725,000−$600,000=$125,000\text{Excess Charged to P/L} = \$725,000 - \$600,000 = \mathbf{\$125,000}

Step 4: Record Impairment Journal Entry at 30 June 2026

Status of Accounts at 30 June 2026

  • Commercial Building Carrying Amount: $5,175,000 - $725,000 = $4,450,000 (matches Recoverable Amount).
  • Revaluation Surplus in Equity: $600,000 - $600,000 = $0.
  • Current-Year Profit or Loss Impact: ($125,000) impairment expense.
  • Current-Year OCI Impact: ($600,000) revaluation decrease.

Step 5: Recalculate Prospective Depreciation for FY2027 (Year Ended 30 June 2027)

Under IAS 36.63, future depreciation must be based on the revised carrying amount of $4,450,000, zero residual value, and the revised remaining useful life of 25 years:

A

$350,000 recognized in other comprehensive income to eliminate the revaluation surplus, and $150,000 recognized in profit or loss.

B

$350,000 recognized in profit or loss and $150,000 recognized in other comprehensive income.

C

Entire $500,000 recognized as an impairment expense in profit or loss, leaving the revaluation surplus intact.

D

$500,000 recognized in other comprehensive income as a revaluation decrease, creating a negative revaluation surplus in equity.

Test Your Knowledge

Under IAS 36.64 and IAS 16.61, when an entity conducts an impairment test on an individual asset and determines that no impairment loss is required because recoverable amount exceeds carrying amount, what further obligation exists regarding the asset's accounting estimates?

A

No further action is permitted because finding no impairment loss conclusively validates all previous accounting estimates.

B

The entity must record a revaluation gain in other comprehensive income to reflect the excess of recoverable amount over carrying amount, as permitted by IAS 36 for tested assets.

C

The entity must restate prior period depreciation retrospectively to reflect the current market conditions that triggered the initial indicator.

D

The indicator that triggered the test requires management to review the asset's remaining useful life, depreciation method and residual value, adjusting them prospectively.
