Financial statements | Additional financial information

Underlying earnings Underlying earnings represents net earnings attributable to the owners of Rio Tinto, adjusted to exclude items that do not reflect the underlying performance of the Group’s operations. Exclusions from underlying earnings are those gains and losses that, individually or in aggregate with similar items, are of a nature and size to require exclusion in order to provide additional insight into underlying business performance. The following items are excluded from net earnings in arriving at underlying earnings in each period irrespective of materiality: – net (gains)/losses on consolidation or disposal of interests in businesses – impairment charges and reversals – (profit)/loss after tax from discontinued operations – exchange and derivative gains and losses. This adjustment includes exchange (gains)/losses on external net debt and intragroup balances, unrealised (gains)/losses on currency and interest rate derivatives not qualifying for hedge accounting, unrealised (gains)/losses on certain commodity derivatives not qualifying for hedge accounting, and unrealised (gains)/losses on embedded derivatives not qualifying for hedge accounting – adjustments to closure provisions where the adjustment is associated with an impairment charge, or for legacy sites where the disturbance or environmental contamination relates to the pre-acquisition period. In addition, there is a final judgemental category which includes, where applicable, other credits and charges that, individually or in aggregate if of a similar type, are of a nature or size to require exclusion in order to provide additional insight into underlying business performance. In 2024 this includes provision for uncertain tax positions in relation to disputes with the Mongolian Tax Authority and the recognition of deferred tax assets at Energy Resources
