External assurance of responsibility reporting

We engage professional assurance providers who combine the strengths of non-financial assurance experience with technical competency in corporate responsibility. This is the fourth year that our corporate responsibility reporting has received independent assurance.

We asked Deloitte LLP to provide limited assurance on selected corporate responsibility performance indicators in accordance with the International Auditing and Assurance Standards Board's International Standard on Assurance Engagements (ISAE3000). The following performance indicators were assured by Deloitte:
