[1] The South African operations with a ZAR functional currency were regarded as a non-foreign operation for purposes of the translation to a USD presentation currency prior to the corporate restructuring. Following the completion of the corporate restructuring transaction in September 2023, the Group’s parent company changed from being a South African domiciled parent company to a UK parent company. As the functional currency of the UK parent company has been assessed to be USD, the South African operations became a foreign operation and the exchange differences  arising on consolidation of these operations, post the corporate restructuring transaction, will be re-cycled through the income statement on disposal.
