[1]

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 is included in 'Profit after tax'. The Group has no further legal or constructive obligation relating to the insured pensions and has reflected this transaction as a settlement.

[2]

The Mongolian Tax Authority required payment by Oyu Tolgoi of US$356 million in relation to disputed tax matters. Oyu Tolgoi continues to dispute the matters and has classified amounts subject to international arbitration as prepayments pending resolution.

[3]

Includes realised gains on currency forward contracts not designated in a hedge relationship of US$10 million (30 June 2020: realised losses of US$200 million).

During the six months to 30 June 2021, the Group invested a further US$15 million (30 June 2020: received net proceeds of US$84 million) within a separately managed portfolio of fixed income instruments. Purchases and sales of these securities are reported on a net cash flow basis within ‘Sales of financial assets’ or 'Purchases of financial assets' depending on the overall net position at each reporting date.
