4 Impairment charges net of reversals Recognition and measurement

Impairment charges and reversals are assessed at the level of cash-generating units (CGUs) which, in accordance with IAS 36 “Impairment of

Assets”, are identified as the smallest identifiable asset or group of assets that generate cash inflows, which are largely independent of the cash

inflows from other assets. Separate CGUs are identified where an active market exists for intermediate products, even if the majority of those

products are further processed internally. In some cases, individual business units consist of several operations with independent cash-

generating streams which constitute separate CGUs.

Goodwill acquired through business combinations is allocated to the CGU or groups of CGUs that are expected to benefit from the related

business combination, and tested for impairment at the lowest level within the Group at which goodwill is monitored for internal management

purposes. All CGUs containing goodwill (note 11), indefinite-lived intangible assets and intangible assets that are not ready for use (note 12) are

tested annually for impairment as at 30 September, regardless of whether there has been an impairment trigger, or more frequently if events or

changes in circumstances indicate a potential impairment charge.

| Other relevant judgements - determination of CGUsJudgement is applied to identify the Group’s CGUs, particularly when assets belong to integrated operations, and changes in CGUs couldimpact impairment charges and reversals. The most relevant judgement for grouping continues to relate to the grouping of Rio Tinto Iron andTitanium Quebec Operations and QIT Madagascar Minerals (QMM) as a single CGU on the basis that they are vertically integratedoperations and there is no active market for QMM’s ilmenite.The most relevant judgement for disaggregation continues to relate to our bauxite and alumina refining operations in Australia whereby wetreat the Weipa bauxite mine as a separate CGU from the downstream assets at Gladstone. Currently, Weipa sells the majority of its bauxiteto third-party customers, whereas the alumina refineries are supplied with all of their bauxite internally. |
