CREDIT RISK The Group is exposed to credit risk on the total carrying value of the investments held in the environmental rehabilitation trust funds. The Group manages its exposure to credit risk by diversifying these investments across a number of major financial institutions, as well as investing funds in low-risk, interest-bearing cash and cash equivalents. MARKET RISK Interest rate risk A change of 100 basis points (bp) in interest rates at the reporting date would have increased/(decreased) equity and profit/(loss) by the amounts shown below. This analysis assumes that all other variables, in particular the balance of the funds, remain constant. The analysis excludes income tax
