	2020
	US Dollars
Figures in millions	Carrying Value	Value in use
Sunrise Dam	229	538

Schedule of Goodwill Allocation

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

	US Dollars
Figures in millions	2020		2019		2018
- Sunrise Dam	118		108		108
- Serra Grande	8		8		8
	126		116		116
Real pre-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)	8.7	%	10.8	%	8.3	%

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 2020 were determined on a basis consistent with the 2019 discount rates.

(1)The value in use of the CGU is $538m in 2020 (2019: $363m; 2018: $750m).
