(a)The provision for other employee entitlements includes a provision for long service leave of US$275 million (31 December 2021: US$272 million), based on the relevant entitlements in certain Group operations and includes US$31 million (31 December 2021: US$60 million) of provision for redundancy and severance payments. (b)Close-down, restoration and environmental liabilities at 30 June 2022 have not been adjusted for closure related receivables amounting to US$391 million (31 December 2021: US$410 million) due from the ERA trust fund and other financial assets held for the purposes of meeting closure obligations. These are included within “Receivables and other assets” on the balance sheet. (c)The way we calculate the cost of fulfilling a contract when assessing whether it is onerous has changed with the adoption of the amendments of IAS 37 (refer to note 2). This has led to an increase in the opening provision by US$17 million. (d)Higher inflation has driven increases in closure and restoration/environmental liabilities. The Income Statement charge for amortisation of discount of US$503 million (30 June 2021: US$207 million) incorporates inflation expectations for 2022 as at the start of the year. We also recorded adjustments to mining properties and charges within operating costs of US$360 million and US$180 million respectively, reflecting changes in forecast cash flows due to our current outlook on inflation being in excess of expectations at the start of the year.
