The central treasury division’s contribution to headline earnings for the year under review amounted to R111 million (2014: R83 million). The increase resulted mainly from an increase in interest received due to higher cash balances and interest rates compared to the previous year.

Net corporate costs amounted to R52 million (2014: R134 million) and were largely impacted by the receipt of an after-tax facilitation and underwriting fee of R99 million from Mediclinic, relating to its acquisition of a 29.9% interest in Spire Healthcare Plc and the concomitant rights offer in the current year.
