##  [Impairment Model](/impairment-model-0) 

 Definition

An accounting concept defining how transactions are recorded, measured, and summarized into financial statements. It governs recognition, classification, and measurement rules that support consistent reporting of performance, position, and cash generation. It does not ensure faithful reporting without well-designed controls, review procedures, and consistent application of accounting policies. It supports decision-making and compliance by producing standardized and auditable representations of financial activity. The concept is generally stable, though reporting standards and system automation evolve over time.



 

 

 

 

 

 





## Principle

Principle

Compare an asset's carrying amount to its recoverable amount or expected future cash flows and recognise a loss when the latter is lower; use consistent, auditable assumptions and techniques appropriate to the asset class.

 

 

 

 

 





## Demonstration

Demonstration

A bank applies a multi-stage expected credit loss (ECL) model that segments receivables into 'no significant increase in credit risk' and 'significant increase' buckets, applying different probability-of-default horizons and forward-looking macroeconomic scenarios to compute provision amounts.

 

 

 

 

## Misapplication

Misapplication

Using a generic percentage allowance across unrelated asset classes, or applying one-off downward adjustments without documented forward-looking drivers, which can understate or overstate impairment and distort comparability.

 

 

 

 

 





## Consequence

Consequence

Timely and systematic recognition of losses, improved credit-risk signalling, and more reliable financial statements that reflect asset value declines and inform provisioning decisions.

 

 

 

 

## Reversal

Reversal

Instead of estimating impairment losses, a reversal scenario recognises increases in recoverable amount that permit writing back previously recorded impairments, constrained by applicable accounting rules.

 

 

 

 

 





## Boundary

Boundary

Applies to financial and non-financial assets where standards require impairment assessment; excludes transient market price volatility that does not affect recoverable cash flows and excludes routine valuation adjustments for marketable securities subject to fair value accounting.

 

 

 

 

 





## Semantic Tension

Semantic Tension

Tension exists between an impairment model and a valuation or pricing model: impairment focuses on recognising loss relative to carrying amount, while valuation models aim to establish fair value or market price irrespective of book value.

 

 

 

 

 





## Synthesis

Synthesis

An impairment model operationalises the accounting rule that assets must be carried at no more than recoverable amount by defining segmentation, risk drivers, forecasting windows and calculation mechanics so that declines in expected cash flows are translated into measurable and auditable loss amounts.
