This is the eighth consecutive year that we have provided a Global Reporting Initiative (GRI) Report. 
During 2015, a review of the GRI G4 General Disclosures and Specific Disclosures was conducted. As a result, we are reporting to a self-declared ‘Core’ accordance level for the reporting period 1 January 2015 to 31 December 2015.

Our separately published 2015 Sustainability Report contains a significant amount of information relating to GRI content whilst some information can also be found in our 2015 Annual Report.
