These are all based on future projections of revenues of the pipeline, anticipated costs and debt service implications.
I note that the PBO's analysis that I believe you are referring to was completed prior to the latest financial projections filed with the Canada Energy Regulator by the Trans Mountain pipeline corporation earlier this year. My comments were based on those filings, which themselves are based on the interim toll rate—that we now know but didn't before—and much more precise projections around revenues, interest costs and operating expenditures of the project itself.
