That's exactly right. It's a number that we determined through a lot of negotiation and discussion among all the members of the IMO. There are several countries involved. The figure of $400 million was determined to be a good figure that didn't put any undue hardship on those who would ultimately have to pay for it, because there currently has never been a spill internationally that would come anywhere near exceeding that amount.
I would also say that the convention does include a provision to make amendments to that particular number without having to go back to and re-ratify the convention. Should it need to be increased, or even decreased for that matter, there is a provision in there that would allow that to happen.
You're right; it is the discussion of multiple countries. We're one of the countries that signed on to it. This is not a unilateral Canadian $400-million figure, if you will.
