The death of British Petroleum? BP's Clean Water Act liability goes up by at least 1% of their current market cap every 2 weeks. Maybe that's why they're trying to move $10 billion dollars off their books before the amount of the fine can be certified.

Fun fact of the day: if you believe the latest, relatively conservative government flow rate estimates of the BP oil leak (19,000 barrels/day), BP is accruing fines at a rate of $81.7 million dollars per day, just for their statutory Clean Water Act liability ($4300/barrel, up from $3,000/barrel in the case of gross negligence under Title 33 USC § 1321).  BP's market cap at the moment is $122.6 billion dollars.
