(a)The fair value movements of our borrowings and interest rate swaps that are in fair value hedge relationships are summarised in note 9.

(b)In 2022, we transitioned the swaps associated to this bond from LIBOR + 5.43% to SOFR + 5.69%.

(c)Rio Tinto has a US$10 billion (2021: US$10 billion) European Debt Issuance Programme against which the cumulative amount utilised was US$1.0 billion equivalent at 31 December 2022 (2021: US$1.1 billion). The carrying value of these bonds after hedge accounting adjustments amounted to US$1.0 billion (2021: US$1.2 billion) in aggregate.

(d)We applied cash flow hedge accounting to this bond and the corresponding cross currency interest rate swap. The hedge is fully effective as the notional amount, maturity, payment and reset dates match. Since 2019, we swapped the resulting fixed US dollar annual interest coupon payments to floating rates. Fair value hedge accounting has been applied to this relationship in addition to the pre-existing cash flow hedge.

(e)On 2 November 2022 our interest rate swap, which converted our fixed coupon interest payments on this bond to 3 month LIBOR +3.79%, matured. Given market conditions, further interest rate swaps were not transacted.

(f)These borrowings relate to the Oyu Tolgoi LLC project finance facility. The project finance facility provides for interest-only payments for the first five years from 2016 followed by minimum repayments according to a stepped amortisation schedule for the remaining life of the facility. The due dates stated represent the final repayment date. The interest rates stated are pre-completion and will increase by 1% post-completion.

(g)The Group’s borrowings of US$11.1 billion (2021: US$12.2 billion) include US$4.0 billion (2021: US$4.4 billion) of subsidiary entity borrowings that are subject to various financial and general covenants with which the respective borrowers were in compliance as at 31 December 2022.
