Yes, our research is collaborative. We have a lot of dialogue between companies, and perhaps individual companies would have their own areas of emphasis. Through dialogue, we work to ensure that the overall program makes sense and is sufficiently comprehensive. As I stressed a couple of times, by corporate policy, all the work we do of an environmental nature and particularly of a reclamation nature is in the public domain, both by the way we execute the work, working with universities, and through efforts to make the information available.
The increase in the number of participants in the industry has been leading us to a greater degree of formalization of this process of dialogue, and that is going quite well. So we have entered into an agreement now with seven companies agreeing to execute and fund research in an integrated fashion.
