(a)At 31 December 2024, the net book value of capitalised production phase stripping costs totalled US$2,326 million, with US$1,947 million within “Property, plant and equipment” and a further US$379 million within “Investments in equity accounted units” (2023: total of US$2,505 million, with US$2,069 million in “Property, plant and equipment” and a further US$436 million within “Investments in equity accounted units”). During the year, capitalisation of US$423 million was offset by depreciation of US$580 million, inclusive of amounts recorded within equity accounted units (2023: US$325 million offset by depreciation of US$324 million). Depreciation of deferred stripping costs in respect of subsidiaries of US$411 million (2023: US$216 million; 2022: US$246 million) is included within “Depreciation for the year”. (b)Adjustment on currency translation represents the impact of exchange differences arising on the translation of the assets of entities with functional currencies other than the US dollar, recognised directly in the currency translation reserve. The adjustment in 2024 arose primarily from the weakening of the Australian and Canadian dollars against the US dollar. (c)Our average borrowing rate, excluding any project finance, used for capitalisation of interest is 7.20% (2023: 7.50%). (d)Additions to “Property, plant and equipment” includes US$144 million of spend on carbon abatement (2023: US$94 million). (e)Refer to note 4 for details. (f)Primarily relates to the acquisition of the remaining 20.64% interest in New Zealand Aluminium Smelters (NZAS). The transaction has been accounted for as a business combination achieved in stages, with our previous 79.36% interest in the NZAS joint operation deemed to have been disposed of. Refer to note 5 for details. (g)Relates to our sale of the Lake MacLeod salt and gypsum operations. Refer to note 5 for details. (h)“Transfers and other movements” includes reclassification between categories. In 2024, this included amounts reclassified from Intangible Assets relating to exploration and evaluation at Simandou (US$732 million) and Rincon (US$1,013 million) following Board approval of “notice to proceed” in February 2024 and December 2024, respectively. (i)Excludes assets held under capitalised lease arrangements. Non-current assets pledged as security represent amounts pledged as collateral against US$4,011 million (2023: US$3,994 million) of loans, which are included in note 20.
