It's just the national standards regime. We do have arrangements, through the North American Energy Working Group, with our standards counterparts in Mexico and the U.S.
The second point I might add to Carol's response is that we're in the business of standards. We do this, and then the government counts on standards to meet its environmental goals. Under that mandate, we're actively looking at standards in other places, because harmonization is a big deal.
In terms of going to the expense, a lot of the cost of making this report is going to be defrayed against our opportunities assessment, if you want to call it that, to determine where the next portfolio standards are going to come from.
