Next you talked about the impact of the price of oil. That was also raised by Mr. Chan, I think. On page 3 you show the difference between Brent, West Texas Intermediate, and Western Canadian Select. Have you done analyses on the differences between those? Obviously there are, somewhat, differences of product. Obviously part of the reason for that difference, especially over the past number of years, has been due to market access. Have you done any studies in terms of what per cent of that difference is due to access to market for those products?
