As regards above I heard the other day that BP self-insure for such spills, so no Lloyds bailout.
I also found this as well. Looks like it's bye-bye dividend for a year or two at least
NEW YORK – Just how many barrels of oil are flowing into the Gulf of Mexico from the Deepwater Horizon spill is one billion U.S. dollars question with implications that go beyond the environment. It can also help determine how much BP and others end up paying for the disaster. Gulf Oil Spill. A clause buried deep in the U.S. Clean Water Act could expose BP and others for civil penalties are not limited to a finite cap – 75 million U.S. dollars as opposed to a cap on compensation for economic damages.
The basic amount, the law is $ 1,100 per barrel spilled. But the penalty may increase to $ 4,300 per barrel as a federal court rules of the spill is the result of gross negligence. The fines were originally set at $ 1,000 to $ 3,000, but that was raised in 2004 to keep pace with inflation, said Tracy Hester, head of the Environmental Law and Policy program at the University of Houston.
So their final costs will be economic damage + $1.1k to $4.3k per barrel.
The estimates run from 5k barrels per day to 100k barrels. It's already been gushing for 45 days and could run for hundereds more.
You run the math.
