There's another component to that as well, which is that organisations are already looking at—they're starting to forward-price decisions. So even whilst the price is still comparatively low at $25 a tonne, they're starting to make investment decisions on the basis that the price will be eventually $40 or $50 or higher. They're not quite sure when that will occur but the point is, if you're having to buy a new plant, that plant's going to have 30 or 40 years in its asset life and at some point during that 30- or 40-year period, you know that the price will be above $40 a tonne—and probably sooner rather than later.
