There are various fund levels. You go first to the ship that has a certificate of financial responsibility. It's backed by an international P and I club or an international insurance company. After that fund is exhausted, you go to the ship-source oil pollution fund, which is Canadian-based. After that fund is exhausted, you go to the international oil pollution compensation funds, and after that fund is exhausted, you go to the supplementary fund, which Canada is now implementing. I can't remember the exact numbers.
