Professor Brian Norton:

I will let Mr. Whelan answer with the details in a second but, essentially, we have an authority policy that sets the levels of authority to sign which is rigorously enforced. Anything I sign comes with a recommendation from a director to sign it having checked all due diligence beforehand. We are all in a clear workflow process and all major contracts come to us in a leadership team meeting and are signed off there. There are very thorough policies on double checking all the due diligence on all major contracts and making sure we look at multi-annual values, because it can creep into higher values by looking at a particular year's value. We look at both contracts that come to us and contracts we pay out.

Is there anything else I have missed?
