Schedule of Goodwill Impairment Assumptions

Based on an analysis carried out by the Group in 2022, the carrying value and value in use of the most sensitive CGU with goodwill is:

	2022
	US Dollars
Figures in millions	Carrying Value	Value in use
Sunrise Dam	230	293

Schedule of Goodwill Allocation

Net book value of goodwill allocated to each of the CGUs:

	US Dollars
Figures in millions	2022		2021		2020
- Sunrise Dam	105		111		118
- Serra Grande	—		8		8
	105		119		126
Real post-tax discount rates applied in impairment calculations on the CGU for which the carrying amount of goodwill is significant is as follows:
- Sunrise Dam (1)	4.6	%	2.4	%	5.4	%

Goodwill has been allocated to its respective CGUs where it is tested for impairment as part of the CGU . The Group reviews and tests the carrying value of goodwill on an annual basis for impairment. The discount rates for 2022 were determined on a basis consistent with the 2021 discount rates.

(1)The value in use of the CGU is $293m (2021: $389m; 2020: $538m).
