The group has a cell captive preference share investment to fund Telkom's post-retirement medical aid liability.

The fair value gains from the cell captive are recognised in profit or loss. The fair value gains are transferred to the non-distributable reserves until the date that the investment and the corresponding fair value gains are realised. On this date the fair value gains are transferred back to retained earnings.

The reserve also represents amounts paid by Telkom to subsidiary, Rossal No 65 Proprietary Limited, for the acquisition of Telkom's shares to be utilised in terms of the Telkom Share Plan.

Fair value of ordinary shares in Telkom are held as follows:
