Sure. As I said in my opening statement, there is a supply and demand issue. You have fundamental issues and you've had two shocks. Think about the last 12 months, when oil prices moved from $70 to $150 and back to $110. Obviously fundamentals haven't changed that much in the last 12 months for supply and demand. They have changed, but not that dramatically. They haven't doubled. We haven't seen such a big difference in what we thought the market would be this year when we were thinking about it last year.
Obviously you have massive amplifications of movement due to money coming in and out of the oil market. Mr. Manzoni is right in a sense, but that doesn't tell me if the price should be $70, $90, $110, or $130. Nobody knows what that price should be; we know that it's amplified. I know only one price I can tell you about, which is basically the marginal cost of producing an extra barrel of oil from a green field. It's probably around $80 or $90 right now, because the dollar is declining. So we know that the marginal price in the long term, if you start a new investment today, is around $80 or $90. That's the only thing I know. I don't know exactly where supply and demand should put my oil prices, because the indicators are all over the place.
