I'll touch a little bit on the costing, and then ask Pat to speak to the contracts.
I totally agree with you on costing. A lot of the work of national defence had originally been more in the acquisition costs. Looking at the previous work of the Auditor General, particularly around the F-35, showed that we need to do better work on life-cycle costing. That is what we do now.
As I said, we've developed a much expanded centre of defence costing that's gone from 30 to 80 people, and international certification as part of the defence policy process. We've looked at all the costing of our projects. We've done that with international expertise, and we've had accounting firms come in and review that. That is the way we go forward on all major purchases.
