BP said on Tuesday it would take a new charge over the 2010 Deepwater Horizon spill after again raising estimates for outstanding claims, lifting total costs to around $65 billion. The post-tax, non-operating $1.7-billion charge BP will take in its fourth quarter results came after claims resolved in recent months were about seven times higher than anticipated, the London-based company said. The claims were part of the Court Supervised Settlement Program that was set up in the wake of the disaster and included nearly 400,000 cases, BP said.
