(a)During the period ended 30 June 2021, the Group entered into an agreement to transfer its partially funded pension obligations in France to an external insurer. The insurance premium was paid by the transfer of the existing pension assets valued at US$89 million plus an additional cash payment of €247 million (US$294 million), of which US$3 million was taken to the income statement. The Group has no further legal or constructive obligation relating to the insured pensions and has reflected this transaction as a settlement. (b)The provision for other employee entitlements includes a provision for long service leave of US$275 million (31 December 2020: US$283 million), based on the relevant entitlements in certain Group operations and includes US$52 million (31 December 2020: US$62 million) of provision for redundancy and severance payments. (c)Close-down and restoration/environmental liabilities at 30 June 2021 have not been adjusted for closure related receivables amounting to US$595 million (31 December 2020: US$574 million) due from the ERA trust fund, the co-owners of the Diavik Joint Venture and other financial assets held for the purposes of meeting closure obligations. These are included within “Receivables and other assets” in the balance sheet.
