Significant judgements and assumptions made by management in applying the related accounting policies

IFRS 3 Business Combinations (IFRS 3)

In applying IFRS 3, management applied the following significant judgements and estimates:

Fair values of material assets acquired

The following material assets were fair valued applying the following valuation techniques and key assumptions:

Non-controlling interests:

Management views the share-based payment transactions with the BEE minority shareholders of the SPVs as in-substance share options that are equity-settled in terms of IFRS 2 Share-based Payment (IFRS 2). These options were not yet exercised at the acquisition date.

IFRS 5 Non-current Assets Held-for-Sale and Discontinued Operations (IFRS 5)

In applying IFRS 5, management made judgements as to which non-current assets and discontinued operations meet the criteria to be classified and measured in terms of IFRS 5 (refer notes 8.4 and 6.1.4).

IAS 36 Impairment of Assets (IAS 36)

In applying IAS 36, impairment assessments are performed whenever events or changes in circumstances indicate that the carrying amount of an asset or CGU may not be recoverable. Management, in particular, identify and track indicators such as the movement in group market capitalisation, volatility in exchange rates, commodity prices and the economic environment in which the businesses operate, to assess whether there is an indication of impairment.

Assets previously impaired are reviewed for possible reversal of impairment at each reporting date.

Estimates are made in determining the recoverable amount of assets which includes the estimation of cash flows and discount rates used. In estimating the cash flows, management bases cash flow projections on reasonable and supportable assumptions that represent management's best estimate of the range of economic conditions that will exist over the remaining useful life of the assets. The discount rates used reflect the current market assessment of the time value of money and the risks specific to the assets for which the future cash flow estimates have not been adjusted.

The impairment assessments performed by management for the different operations resulted in no impairment for the year ended 31 December 2020, except for the ECC operation. Judgements were required in the determination of key variables and future market conditions, particularly in relation to the parameters included in the following table:

Management considered and assessed reasonably possible changes for the key assumptions and have not identified any instances that could cause the carrying amount of the coal operations to exceed its recoverable amount.
