Halliburton has wrapped up most of its lingering liability for the 2010 Gulf of Mexico oil spill with a $1.1 billion settlement announced on [September 2]. The pact will resolve accusations that Halliburton's cement work on the ill-fated Macondo well contributed to a disaster that killed 11 rig workers and spewed millions of barrels of crude into the gulf. First off, the timing of the settlement announcement may signal that U.S. District Judge Carl Barbier is nearing a decision on the Big Question of how to apportion overall blame for the spill-and, more specifically, what kind of additional legal bill faces BP as the main operator of the well. The British company has already paid out more than $28 billion and faces additional liability that could total an additional tens of billions. The $1.1 billion settlement represents Halliburton's biggest payout yet in the disaster. Transocean, owner of the drilling rig, settled a batch of claims last year for $1.4 billion. Beyond settlement payouts, the Gulf spill litigation is costing the various companies implicated in the disaster enormous legal fees-or, more precisely, it's costing their insurance carriers large amounts. Prior to settlement, Halliburton had incurred fees and expenses of $294 million, $263 million of which was covered by insurance, according to a filing in July. Halliburton had set aside reserves of $1.3 billion for costs related to the spill.
