Thank you very much.
On the diluted bitumen, I can't give you the results of the research. They're not ready yet, but we hope they will be out soon. We've been working pretty hard on this, and we've also been testing our research in a peer review manner. We are looking at the question. The answer is not as simple as you just characterized it—when the diluted bitumen hits water it sinks. That's the question we're trying to answer: what happens to it when it hits water? It can depend on a variety of factors, as you can imagine.
