The funds comprise the following investments:
These assets are primarily rand denominated. Cash is held in short term fixed deposits or earns interest at floating inter-bank rates and bonds earn interest at a weighted average fixed rate of 9% (2007: 11%) and are fixed for an average period of 10.2 years (2007: 9.5 years). These assets are recorded 'at fair value through profit and loss'.
These funds are not available for the general purposes of the Group. All income from these assets is reinvested to meet specific environmental obligations. These obligations are included in environmental rehabilitation costs under non-current provisions (see note 25).
