situation. >> finally, i want to ask about the moratorium. we've seen some of these rigs are moving to africa, moving to brazil. they are not going to be back. we are talking about thousands of jobs lost. it's in your interest to make decisions, but you cannot sit on a rig with costs for six months or longer. >> with the announcement about a containment system we can put in place, with the government insisting on us and virtually already complying with higher well design standards in terms of the minimum requirements, i think over time with improved oil spill response plans as we learn better how to take oil out of water, all those provide important elements to moving through a moratorium. what i think ought to happen, you can separate the higher risk work from the lower risk work. >> thank you very much, marvin
