I think many considerations go into a cabinet decision as to a bill, cost being one of them. I think all members of any cabinet would want to know as much as they possibly could about the potential costs. That being said, it's sometimes very difficult to determine what those costs are. They're really highly contingent. So it may be very difficult for them to try to calibrate that cost, especially if it's many years out.
