And I note, in the whole process—and this is the rules for auctioning in the New Zealand emissions trading scheme (ETS)—what the Minister didn't quite explain is that each bidder puts in a bid stating their price and the quantity of the NZUs that they want to acquire, they are then ranked from highest to lowest. Then, each successful bidder receives a quantity bid at prices at, or above, the clearing price. That uniform price means that all bidders pay the same clearing price and that price is the lowest successful bid. So effectively what the concern is here is that people in the market could get together, come to an agreement, a side agreement—which would probably be illegal—and then ensure that the low bid was very low, acquire those units at that very low price, then sell them on the secondary market later, or, in fact, wait for the price to go up. So I think we understand why you'd want to do that, and we do need to get this to function properly, and we want confidence in the market, but the other—in terms of fiscal risk, at $25, it's just over $2 billion, just over $2 billion, up to $20, $25. Actually, that's at $25, it's more likely to be $3 billion. So there is a significant fiscal risk for the Crown, and I think that's great that we get this sorted.
