  During the years ended 31 December 2014 and 2013, the Board of Directors awarded 2,839,626 and 1,237,994 RSUs 
  to certain employees. These awards were made in accordance with the long-term equity component of the

  these awards has been recognised within the financial statements. This information is summarised for the Group
