To add to that, I think what Carol is referring to is that we were doing monitoring already, and so what this agreement does is step it up, and so it's incremental to that.
Let us go back and try to find the figures for you in terms of what we're spending now. In terms of the future, it may be more difficult to provide a precise estimate, at least until the MOU is finally signed, but let me look at what we can do. We can certainly tell you what the incremental is that we've seen thus far over the past year.
