To your first question, we certainly have engaged in that conversation, and I'd like to add that it's a very active conversation around the table.
With respect to your second question, I think that with respect to a carbon tax there will be a lot of pressure on ensuring that those taxes that are collected go back into the economy to support initiatives that will lower carbon. Just in general conversation, we haven't made any firm decisions, but I think we'd certainly be looking at lower-income issues, starting off with homes that require it, to help them along the way. At least at this point, we certainly do not view it as a tax grab.
