The two regimes are different. When we talk about world class, we're just talking about oil, such as oil handling, bitumen, oil-going ships. The one that we are proposing today for the Marine Liability Act is very narrow. It's just chemicals or hazardous and noxious substances and just the liability aspect. It doesn't include prevention measures or response measures.
As to why I say $400 million is enough, I won't categorically say it's enough; what I will say is that internationally there's never been a chemical spill that has exceeded that amount in terms of claims.
