There's no question that the maximum security costs are higher than the other two. As we discussed earlier, there is the unusual situation right now that the minimum costs are actually higher than the medium, only for the reason that we have additional surplus capacity in the minimum.
What I would say is that the costing factor really kicks in, in relation to the maximum security space. If you look, for example, at the comparison of the cost from medium to maximum, you're looking at a jump, in 2004-05 figures, of roughly $75,000 to $113,000. That's where you see the big jump.
