A judge’s ruling in the 2010 Gulf of Mexico oil spill case that could cost BP an additional $17.6 billion in fines sent the company’s shares tumbling Thursday. BP was found by U.S. District Judge Carl Barbier to have acted with “gross negligence,” leading to the worst U.S. offshore oil spill. The ruling triggers the highest possible fines under the Clean Air Act of $4,300 per barrel of oil spilled.
The number of barrels spilled is being debated but is likely to fall between 2.4 million and 4.1 million barrels. That translates to a fine of between $10.3 billion and $17.6 billion. While BP has already spent at least $24 billion in spill-related expenses to date, including cleanup costs and payments to affected businesses and residents, it had set aside just $3.5 billion to cover what it thought would be a much smaller fine for actually spilling the oil.
BP shares fell $2.82, or 5.9%, to $44.89, reducing the company’s market value by $8.66 billion. The shares were near $60 per share just prior to the April 2010 spill. Bruce Huber, associate professor of law at the University of Notre Dame, who specializes in environmental, natural resources and energy law said investors had already assumed BP would pay a bigger fine than the company hoped it would face.
That protected BP’s shares from falling even further, Huber said. Analysts at Jefferies, for example, estimated fines of $10 billion. Raymond James analysts estimated fines of $8 billion. Still, investors have a few new concerns based on Thursday’s ruling: The prospect of an additional big outflow of cash and not knowing how or when the fine will be finalized or paid. BP said it would appeal the ruling, a process that puts off a final decision on the size of the fine and also likely delay other pending court cases concerning the spill.
