Mr. Ciarán Breen:

Exactly. What we tried to do in those cases was estimate what the likely costs would have been and what kind of savings we would have made. The Office of the Comptroller and Auditor General stated - rightly and I understand why - that was speculative on our part and that we might be overclaiming credit for what we were saving. Following that, we discounted doing that and we only now record what our actual savings are between the bill of costs and what we ultimately settle at.
