The voluntary principles set out guidelines and principles around how companies should work with both public and private security. They talk about training. They talk about engagement with communities around these things and a number of other factors. The implementation of these principles is really intended to drive performance improvement around how we work with security forces where they are used.
For our part, the commitment requires our companies to implement security management systems consistent with the voluntary principles. Starting next year, the companies that are using security forces will start to report through us, through our TSM annual report, describing their approach to implementation and describing their approach to assurance, that the principles are being used appropriately. That will be included publicly in our annual report.
The other thing we've also done is to create a communities of practice of security practitioners within the industry to facilitate knowledge transfer, sharing of best practices, and discussions of how issues are dealt with.
