At the end of the reporting period, the Group’s exposure to foreign currency risk was as follows (denominated in US dollars):

	Assets				Liabilities

Sensitivity Analysis

The following table illustrates sensitivities to the Group’s exposure to changes in exchange rates. The sensitivity analysis includes external loans as well as loans to foreign operations within the Group where the denomination of the loan is in a currency other than the currency of the lender or the borrower. The table indicates the impact on how profit and equity values reported at the end of the reporting period would have been affected by changes in the relevant risk variables that management considers to be reasonably possible. These sensitivities assume that the movement in a particular variable is independent of other variables, each scenario assumes no change to other variables.
