The Thomson-Extel annual Investor Relations Survey is considered the most prestigious and independent Investor Relations performance evaluation, since 250 investement banks and 2,500 institutional investors vote throughout Europe, USA and Asia. The process is monitored and ratified by the auditing firm Deloitte, while the votes are calculated according to the significance and the size of the company of each participant, ensuring in this way the objectiveness of the evaluation.
