We do, as my ADM has mentioned, work closely with industry, so we are current with our existing technologies. But what we are trying to do is push the envelope, so we are trying to develop, for example, much more aggressive tailings treatments at our laboratories so we can then say to the producers that this is a way to do it, this is what it would cost you, and this is the effect on the water chemistry, and how about it?
So we are trying to stay ahead of the industry in those terms.
