Briefly, the work we did in 2000 was a bit different from what we normally do. Normally we do what we call audits. This was actually a study, which is a bit more broad-ranging and exploratory.
In that study in 2000--and we'd be happy to give you the references--we looked at how level the playing field was in the energy sector. One of our conclusions was that one of the places in which it was distorted was with respect to federal government support for oil sands. Again, we'd be happy to give you details.
