BP, the energy giant formerly known as British Petroleum, has agreed to plead guilty to 14 criminal charges and pay $4.5 billion in fines and other payments to the federal government as a result of the 2010 Deepwater Horizon disaster in the Gulf of Mexico, according to sibling publication The National Law Journal.

The settlement adds to the already hefty price tag incurred by BP as a result of the massive offshore oil spill, the second-largest such disaster in history.
