[1] | During 2014, the South African Revenue Services ("SARS") issued a Finalisation of Audit Letter ("the Audit Letter") stating that SARS had disallowed $1,014.2 million of GFIJVH's recognised capital allowance of $1,586.0 million. The company has not received an assessment from SARS disallowing the $1 014.2 million and the company believes it is more likely than not it has a defendable position over this matter.
