Cash-generating units and corporate assets

Before you can test for impairment, you have to decide what to test. Draw the cash-generating unit too wide and losses in one part hide behind profits in another; draw it too narrow and every weak asset is written down. This guide explains how IAS 36 defines a CGU, with retail, transport and manufacturing examples.

Short answer

A cash-generating unit (CGU) is the smallest identifiable group of assets that generates cash inflows largely independent of the cash inflows from other assets or groups of assets. IAS 36 tests an asset for impairment on its own only if it generates such independent inflows; otherwise it is tested as part of its CGU. If an active market exists for the output of a group of assets, that group is a CGU even if the output is used internally. Corporate assets, such as a head office, are allocated to CGUs.

How do you identify a cash-generating unit?

Look at cash inflows only; shared costs do not combine units.

The test looks at cash inflows, not outflows or shared costs. How management monitors operations, by product line, business, location or region, and how it decides whether to continue or dispose of assets, are useful evidence. Once identified, CGUs are kept the same from period to period unless a change is justified, and any change must be explained.

CGU examples

SituationCash-generating unitWhy
A retail chain with 50 stores in different towns, each with its own customersEach storeEach store's sales are largely independent of the others
Two stores in the same shopping centre that share customers and are managed togetherPossibly the two togetherTheir inflows are not independent of each other
A bus operator with a contract requiring it to run five routes, one of which loses moneyThe five routes togetherIt cannot drop the loss-making route on its own
A mine whose ore is processed internally but could be sold on an active marketThe mineAn active market for its output exists, so it is a CGU at market prices
A telecom operator's national mobile networkOften the whole network in a countryIndividual sites do not generate independent revenue

A worked example: a retail store

A retailer's store A has a carrying amount of 2.0 million, made up of fit-out and its right-of-use asset. Sales have fallen after a competitor opened nearby. The store's value in use is 1.6 million and its fair value less costs of disposal is lower. As the store is a CGU, the impairment loss is 0.4 million, spread across its assets in proportion to their carrying amounts. The rest of the chain's profits do not shelter it. See value in use.

How are corporate assets treated?

Corporate assets, such as a head office building, IT systems or a research centre, do not generate independent cash inflows. If a portion can be allocated to CGUs on a reasonable and consistent basis, for example by revenue or by carrying amount, each CGU is tested including its share. If not, the CGU is tested without them first, and then the smallest group of CGUs to which the corporate asset can be allocated is tested including it.

Do right-of-use assets belong in a CGU?

Yes. Right-of-use assets under IFRS 16 are part of the CGU's carrying amount, alongside the property, plant and equipment the unit uses. To compare like with like, the lease liability is normally excluded from the carrying amount and the lease payments excluded from the value in use cash flows, or both included consistently.

How does goodwill fit in?

Goodwill does not generate cash flows on its own, so it is allocated to the CGUs or groups of CGUs expected to benefit from the business combination. Each group must be no larger than an operating segment before aggregation. See goodwill impairment testing and IAS 36 explained.

Questions people ask

What is a cash-generating unit under IAS 36?

The smallest identifiable group of assets that generates cash inflows largely independent of those from other assets or groups.

How do you identify a CGU?

Look for the smallest group of assets whose cash inflows are largely independent, using how management monitors operations and makes disposal decisions as evidence.

Is each store in a retail chain a CGU?

Often yes, if each store's sales are largely independent of the others.

How are corporate assets tested for impairment?

They are allocated to CGUs on a reasonable and consistent basis, or tested with the smallest group of CGUs to which they can be allocated.
