I guess what I'm saying is, do you have a ballpark figure? I think one of the concerns that people quite rightly have is that if we're going to have the extension of the mission to 2011 and it's going to come with the demands we've been asked for--the 1,000 troops, the helicopters--it's a fair question to get an approximation.
I understand what you're saying. It depends on whether you're going to lease or buy; there's a difference in what you're going to get. But is there an approximation of what it will cost? I guess you're saying that we don't have that approximation to date.
