Indicators identified by an asterisk (*) were the focus of more in-depth analysis, enabling the Statutory Auditors to express an assurance specifically for these data.
Their assurance statement, detailing the work they performed as well as their comments and conclusions, appears on page 45 of the Sustainability Report 2008.
