Summary of Effect of Change in Finance Expense on Group's Shareholders' Equity

The table below summarises the impact of increases/decreases of the exchanges on the Group’s shareholders’ equity in case of shares. The analysis is based on the assumption that the share prices quoted on the exchange have increased/decreased with all other variables held constant and the Group’s investments moved according to the historical correlation with the index.

The tables below summarise the impact of increases/decreases on the Group’s shareholders’ equity in case of changes in the key inputs used to value the preference shares. The first analysis is based on the assumption that the market-related discount rate has increased/decreased with all other variables held constant. The second analysis is based on the assumption that the timing of the cash flows used in the life-of-mine model increased/decreased with all other variables held constant.

Statement [LineItems]

Summary of Effect of Change in Finance Expense on Group's Profit or Loss had LIBOR and Prime Differed as Indicated

The table below summarises the effect of a change in finance expense on the Group’s profit or loss had LIBOR, JIBAR, prime and BBSY differed as indicated. The analysis is based on the assumption that the applicable interest rate increased/decreased with all other variables held constant and is calculated on the weighted average borrowings for the year. All financial instruments with fixed interest rates that are carried at amortised cost are not subject to the interest rate sensitivity analysis.
