As I said, every industry has a regime under which it deducts and recovers costs. In the oil sands area, as you know, in the most recent budget one of those provisions--characterized by some as a subsidy--was removed. As I said, it doesn't look as if the overall burden on our industry is particularly lighter than it is on others. And of course you also need to remember there's a huge reinvestment rate and a great many companies are not turning a profit yet, in particular among the smaller sectors of the industry.
