Okay. I'm interested, because in business we talk about the high investment in terms of having more refining capacity, yet when I look at Mr. Quintal's figures, Esso's profits in this particular one--the refining margins--are records. They are over 100% in six years. So I'm wondering what the barrier is. It doesn't matter if it's $100 million or $50 billion if its margins are huge. If margins are large, what's the barrier, do you believe?
