(a)At 31 December 2022, trade and other financial receivables are stated net of allowances for expected credit losses of US$59 million (2021: US$57 million). We apply the “simplified approach” to trade receivables and receivables relating to net investment in finance leases and a “general approach” to all other financial assets.

(b)At 31 December 2022, other receivables include US$329 million (2021: US$388 million) related to Energy Resources of Australia Ltd (ERA's) deposit held in a trust fund which is controlled by the Government of Australia. ERA are entitled to reimbursement from the fund once specific phases of rehabilitation relating to the Ranger Project are completed. The fund is outside of the scope of IFRS 9 “Financial Instruments”.

(c)These prepayments will be charged to Group operating costs as tolling services are rendered and product processing occurs.

(d)There is no material element of receivables and other assets that is interest-bearing or financing in nature. The fair value of current trade and other receivables and the majority of amounts classified as non-current trade and other receivables approximates to their carrying value.
