Commitments relate to amounts for which the group has contracted, but that have not yet been recognised as obligations in the summarised consolidated statement of financial position.

The group operates a number of businesses in jurisdictions where taxes may be payable on certain transactions or payments. The group continues to seek relevant advice and works with its advisers to identify and quantify such tax exposures. Our current assessment of possible withholding and other tax exposures, including interest and potential penalties, amounts to approximately R1.8bn (2018: R1.7bn). No provision has been made as at 31 March  2019 and 2018 for these possible exposures.
