We haven't seen the design of the emission credit system because it's still under construction, as I've said. I will assume that the bureaucrats have looked at what was available. They have certainly looked at that success story. They may have looked at what is going on elsewhere, such as in California, the U.K., Japan, and in the European Union, where they all have something.
One thing I have to clarify, though, and Richard will just specify, is that there was no commitment that we have seen anywhere where the government was planning to buy hot air.
