Since the blowout preventer on the well failed, if Cameron is found liable for all or part of the spill, its revenues and future outlook could be severely impacted. "The negative spillover effects from the [blowout preventer] failure could relate to other product lines in the pressure control and subsea areas and to its relationships with Transocean and BP, which are major customers. We believe there is a risk that the negative spillover effects over the next few years could result in lower sales orders that would have the potential to directly affect Cameron's cash flows, its business and financial risk profiles, and possibly our view of its credit quality and corporate credit rating," said S&P. Halliburton ( HAL ), which provided the cementing and other well services for the Macondo well, could handle a short-term slowdown in offshore drilling and can afford to make payments for some potential liability for the spill.
