CHANGES IN THE YEAR
In 2015, we chose not to undertake external assurance on environmental data. Instead, we elected to conduct
internal management reviews of the main systems and processes in our network and non-network operations
which inform the Group’s energy and greenhouse gas profile. This review was conducted across a sample of
MTN countries. Unlike in previous years, we elected not to conduct external assurance of our energy and
carbon emissions due to a number of strategic changes within MTN. These changes have increasingly
impacted how we actively reduce our consumption of energy, and how we report on our carbon emissions. In
2015, we no longer obtained external assurance on operations with a fraud management framework as we
had achieved our target in terms of rollout. We also ceased to obtain external assurance on the small opco
cluster’s net promoter score (customer satisfaction performance), considering that the focus of the integrated
report is on the Group’s most material operations (  IFC).
Note:
Data definitions remained consistent with the prior year. For the independent assurance statement, see 118.
