I can start. I'd say the same thing as I said at the last committee meeting. In terms of the $3 billion impact of going from four years to ten years, it was calculated based on the corporate tax rate reductions, including the resource tax rate reductions, going from 2006 or 2007 on for six years.
You have to take into account the fact that, as Mr. Bruce indicated, there are probably not going to be any further conversions into income trusts over that period. Also one of the big offsets that reduced our 2006 estimate was the one-time capital gains, which we estimated on conversions and IPOs in 2006. That doesn't occur in other years over the transition period.
So you don't have to have a very significant—in fact you could have a very minor—organic growth rate, and that's consistent with the issuances that have been made even over the past few months on income trusts.
