Okay I see that you used the QB2 Reserve case info, great. However you used QB2 EBITDA 100% numbers to determine Teck's respective returns.  Teck doesn't own 66.6% of the project.  Teck owns 66.6% of the JV but the JV only owns 90% of the project.   Shouldn't that factor into an Apples to Apples sanction comparison?
