How would you come to that?
As an example, when the PBO took the costing and then extrapolated that over the next 20 years, have you done a similar process based on the success to date, the fact that we've spent close to $300 million in upfront costs and yet we've received $435 million in contractual guarantees and contractual programs that are a benefit to Canada?
Did you extrapolate from these numbers? How did you come to that figure?
