During these discussions that have come about and the concern about it...it's a whole review brought about not only by yourselves but by the industry and those within it.
Do you know why it is different? When you look at capital cost allowance schedules there seems to be a wide variation. So I'm going back to the first question I had on who defines it. There seems to be a wide variation from country to country, mostly with the United States because it's the largest trading partner in a lot of the cases. Can you tell us why there may be that sort of difference, when there's collaboration between industry and your ministry?
