Well, certainly we want to employ best practices. As I said, we participate in several industry forums to ensure we are applying best practices, and those even go beyond just oil sands but to other mining industries.
I'll defer to the regulators on whether more regulatory oversight is needed. I am aware that there are initiatives under way, both by the federal government and by the provincial government, to put in place some working groups to explore other enhancements or different approaches to managing tailings. We very much want to be a part of that, because we endeavour to make this better.
