We look at it as five buckets. There's similar evidence that's included in our CER testimony by the company, which is focusing on uncapped costs—in other words, costs that we pass through to the shippers—but when you look at the whole project, the same categories basically apply, so I'm going to go through these five quickly.
Evolving and additional compliance requirements are one bucket. That's about $5 billion, or about 19% of the increase, and I'm going against the $7.5-billion estimate when the project was approved to go ahead. Information maturity is about $7.2 billion, about 27%—I'll come back to what some of these things are in just a second—indigenous accommodations are $2.3 billion, 8%; stakeholder engagement and compensation is $3.5 billion or about 13%; and the aforementioned exogenous factors total $8.9 billion, or 33%.
Those are five big buckets in our way of thinking.
