We haven't done our own economic study. We primarily looked at the government and at some of the work the government was initially doing around the modelling on this. We looked at other private sector studies that have been done through think tanks and other places and a wide variety of union-sponsored ones as well as private sector-sponsored ones.
I think Mr. Beatty is right in terms of companies having their own economic studies. My guess is that you could call companies up here from within the same sector and they would each tell you they had a very different outcome largely because of where their manufacturing footprint is and where their customer base is. Those vary quite a bit and they are hard to pin down.
