Ms. Donnelly, you've very provocative statements and an interesting perspective we haven't had yet, around the market—and I know Mr. Bramley might want to take the microphone, as well—but the thing I don't understand is, with the amount of emissions trading going on in the world today, you've talked about a massive oversupply of credits. How has the market simply not completely collapsed down to next to nothing if there's such a massive oversupply?
