It's plausible and consistent with what we've seen to date.
Kinder Morgan didn't want to expand the pipeline. The government bought it for that reason. Now, according to our analysis of the costs, which have gone up, if we look solely at the financial transactions, it's likely that the government will lose money on this project. That's why there's a discount rate of about 8%, set by the Crown corporation that owns the pipeline. So your analysis is quite plausible.
However, it's also possible that a buyer feels the risks are much lower than our analysis indicates and decides to purchase it at a price that would satisfy the government.
