Yes. They have a number of tests that are really standard across the board for pipeline tolls. It starts with, first of all, that costs have to be prudent. For the assessment of the costs that are before them, they will do an assessment and the costs can't go into the tolls if they're not found to be prudent.
Secondly, tolls have to be “just and reasonable”. There are a lot of dimensions to that, but the “just” is really fairness, and they look at what the underlying agreements were between the parties that agreed to the commercial arrangements. “Reasonable” encompasses a lot of things, such as competitiveness in the marketplace.
