text: ***Interest Rate Risk***
  Interest rate risk is the risk that the fair value of the future cash flows of a financial instrument will fluctuate 
  because of changes in market interest rates. The Group’s exposure to the risk of changes in market interest rates 
  relates primarily to the Group’s long-term debt obligations with floating interest rates. 
  
  *Interest Rate Sensitivity Analysis*
  Based on the net debt position as at 31 December 2014 and 2013, taking into account interest rate swaps, with 
  all other variables remaining constant, the following table represents the effect on income as a result of changes 
  in the interest rate. The impact on equity is the same as the impact on profit before tax.
