I actually would like to go back to this issue of redundancy. I think when we here in the spring there was some explanation of what's required on an offshore rig in terms of redundancy, but I'd like you to just cover that again. I understand there is double, triple redundancy. The problem in the gulf seems to have been that they had started with bad cement work and then it impacted the blowout preventer. Could you go through what is required? And then we'll move on to another question.
