SHOOT: I don't think BP's stock will ever regain its value. The company has become reviled internationally. The brand value has been blackened and sullied beyond redemption.
Based on the maximum amount of oil possibly spilled to date, that would translate to a potential civil fine for simple discharge alone of $2.8 billion. If BP were found to have committed gross negligence or willful misconduct, the civil fine could be up to $4,300 per barrel, or up to $11.1 billion.
