The $400 million was set by international convention, which involved a lot of discussion, debate, and dialogue among the several countries that sit there. Through consensus, they came up with the $400-million limit.
Just to clarify, for hazardous and noxious substances, there has never been a chemical spill that came anywhere near that amount. You mentioned the Exxon Valdez. That would be covered under a separate regime. There is a separate oil spill regime. That particular regime currently has upwards of $1.4 billion available. There are two different regimes: one for chemicals and another one for oil.
