Thank you very much for allowing me to finish my comment.
I was simply trying to respond to Mr. Brock's question regarding the processes around how we review whether or not we can engage in work with a particular organization, contractor or subcontractor. I was just trying to finish the statement that we do have processes whereby we check clients and we check the nature of the engagement we're being asked to undertake. For all of our public sector engagements, we have three partners who actually have to sign off on something before we're allowed to proceed: the engagement lead partner, a secondary partner who is responsible for looking after the engagement-specific process questions and then another quality partner.
I simply wanted to say that our processes are incredibly rigorous. They're very detailed. They are reliant on point-in-time information, and our systems continuously update based on current information as things evolve. That's what I wanted to finish.
Thank you.
