Mr. David Gunning:

We are constantly in receipt of new claims, of which we do an analysis on an ongoing basis. That analysis is updated monthly. In terms of where we are currently, last month's analysis was only recently finalised. We are content in terms of the way in which we are defending the claims. We think we have put a robust system in place to defend those claims. Some of these claims - I must say this - are claims for additional money for the contractor, some of which the contractor is entitled to.
