It's a different animal, I think. If you take say, the Sam Croft or the Tom Madden, the way we've got those rigs stacked, those rigs are two years old, two years out of the shipyard. I would say the startup effort on those and of course we're keeping marine crews on them, so we can put to sea if we need to. And all the marine systems are hot, the drilling equipment is preserved essentially. In those rigs, the startup of those rigs really is a function of crews and man days. There's a not a lot of capital requirements. There's not a lot of additional expense or other things. So it's a function of crewing the rig up, running the equipment and getting it hot and sparing up those kinds of consumables versus the rigs that have been idle for some period of time and are a little longer in the tooth. When you talk about BOP recertification and mooring inspections and hoisting equipment, they maybe little to you, but – to some people, but they could be extremely costly. When you start getting into a string riser that's five, six, seven years old and laid up for couple of years, the cost to inspect that riser and refurbish that riser and ensure that it's good for the pressures that are intended, particularly Gulf of Mexico, where you really can't work a rig that's a 10,000-pound BOP system anymore. The time and the cost of that gets – can compound very quickly. And so, newer equipment is going to be better, easier, we'll say that some of these ships that have been cold-stacked and some of the higher tech equipment have been cold-stacked depending on the condition and how long it was really in service before, there could be some software challenges with some of those rigs that I think that software changes very quickly. So there will be some challenges, some of the late generation rigs that have been cold-stacked that have been working for a while, but for instance, I can't speak to the whole fleet, I can speak to our fleet, but rigs like the Croft and the Madden, we don't see any real challenges in those, even the day in the Adkins, we've removed those thrusters and put them on bottom, but the age of those rigs and the condition of those rigs would make them fairly easily restarted, if we had the right opportunities.
