Yes. If we got into a very long period in which the stock didn't, say, go above 300,000 or 400,000 tonnes, we could be in for—I'm sure you've heard it mentioned—a regime shift in which the stock stabilizes at a much lower level than in the past. If that persisted for a long time, we would perhaps have to revisit the reference point issue and take into consideration that things such as this happen.
We are very aware of the possible importance of the environmental conditions in the long term and of how they can affect the reference point.
