I think your logic is correct. That isn't something we looked at with this audit. We didn't look at the scope of what the different options are within emission trading schemes. There's obviously a lot. There's the western climate initiative, the New England governors' conference, the Western Governors' Association. Provinces are engaged in the western climate initiative and the registry, so there's a lot going on. We looked specifically within the context of what the KPIA requires.
