It's always difficult to exactly quantify the costs of delay, but every time there is a delay it certainly creates an opportunity to introduce additional studies, which sometimes add very little value considering the costs just for people to participate—even on the industry and government side—in the process in asking and re-asking questions and calling for review that has already been reviewed.
It tends to extend the timeframes, of course, with the costs of that. It puts in question financing mechanisms. I'm not an economics major, but it starts to enter into those difficulties.
