Part of what we do is to see what research is being done elsewhere. In fact, if you look at our CSA session a couple of years ago, which Jay can speak to, it was largely a review of research that's being done elsewhere. But it is something that we're interested in. We do have a study that's looking at different types of environmental analyses, including this type, but we have not sponsored something on a life-cycle approach with respect to closed containment.
