(i)	Additions relating to leased mineral reserves which fall outside the scope of IFRS 16.

(ii)	See note 20 for more detailed information on right-of-use assets and lease liabilities of the Group.

(iii)

No impairment charge was recognised in 2021 (2020

: $263

million including $9 million related to leased right-of-use assets (note 20); 2019:

$9 million). The charge in 2020 principally relates to the write-down of specific assets relating to our UK business within our Europe Materials segment following a strategic review of its operational footprint, together with impairments booked in respect of two CGUs in the same segment. An extended period of lower than anticipated demand and reduced price growth resulting from the combined economic impacts of Brexit and

COVID-19

were the primary drivers of the impairment charge. The recoverable amount of these assets is their

value-in-use

of $185 million and is calculated using real

pre-tax

discount rates ranging from 7.3% to 7.7%.
