Again, the departments you talked to earlier today have done a fair amount of work in these areas. They know these areas very well. They know these areas better than we do, and they've come up with an assessment of what will cost them, among the many bills you've been looking at, and what will not cost them.
If they say they don't think this is going to cost them anything, they are signing off on that and are not asking for funding for it, so they have a fair amount of confidence.
