Management considers a number of factors in assessing whether to raise deferred tax assets on unutilised tax losses and capital allowances. These include a yearly analysis of trends in current and past performance of the entity which forms the base of a five-year forecast to determine if an entity will be in a position to utilise such tax losses or capital allowances in the foreseeable future, as well as any other key considerations that may affect current or future performance of the entity. Deferred tax assets on unutilised tax losses and capital allowances are only raised where forecasts indicate a reasonable expectation that such tax losses or capital allowance may be utilised to reduce a potential future tax liability.

The Group has not recognised deferred tax assets to the value of R714 million (2020: R541 million) relating to tax losses available to carry forward against future taxable income in these financial statements due to uncertainties regarding the utilisation of these losses in the foreseeable future. These losses originated predominantly in the UK businesses (2020: UK and Scanmed). None of these losses are expected to expire.
