Impairment assessment

As mandated by IAS 36, management performed an impairment assessment on the basis set out in notes 1.17 and 37. Significant judgement and estimates were made in determining the value-in-use calculation. The recoverable amount was determined using the value-in-use calculation via a discounted cash flow model. Based on the results of the assessment, no CGU impairment adjustment was recognised for the current reporting period. There was an impairment of the Boshoek smelter by R574 million, in addition to the impairment of another specific asset by R1 million. This brings the total impairment loss for the year to R575 million. Note 37 further explains management's impairment assessment.

Depreciation

R354 million depreciation and amortisation is recognised in the statement of profit or loss and other comprehensive income, which comprises R350 million resulting from property, plant and equipment and R4 million of amortisation resulting from intangible assets.

Impairment assessment*

As mandated by IAS 36, management performed an impairment assessment on the basis set out in notes 1.17 and 37. Significant judgement and estimates were made in determining the value-in-use calculation, and this is further explained in note 37. The recoverable amount was determined using the value-in-use calculation via a discounted cash flow model. Based on the results of the assessment, no CGU adjustment was recognised for the current reporting period. There was no specific asset impairment.

*The Group has revised the wording of the disclosure of the prior year's impairment assessment in notes 3 and 4 to be consistent with the current year's disclosure of the impairment assessment.
