The following table illustrates sensitivities to the Group’s exposure to changes in exchange rates. 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.
