Deferred tax asset

Deferred tax assets of the Company are reviewed at the end of each reporting period and are reduced to the extent that it is no longer probable that the related taxation benefits will be realised. Management is of the view that the deferred tax asset raised is recoverable and it is probable that future taxable profits will be available against which deductible temporary differences can be utilised.

The Company had an assessable tax loss of R8m at 31 December 2022 (2021: R20m). The tax loss does not have an expiry date and no deferred tax asset has been raised on this loss.
