Mr. Masters, I don't want to cut you off, but I only have six minutes. I have one little follow-up question along the same lines, if you don't mind, which I will direct to Ms. Russell.
In our context, we're faced with the same issue. You have contradictory reports on this phenomenon, if I can call it that. From a public policy point of view, it's in our interest to do what we can to make sure we have prices for oil that are reflective of supply and demand. If we assume that there are some issues, what is one to do, Ms. Russell, to bring some effective public policy to bear on them?
