 Just to get it out of the way when you talk about maintenance on ships that's actually deferred maintenance which presumably at some point to maintain readiness you would have to spend down the road right? That's exactly right. I mean there is a it's like it's like with your car you can defer maintenance to to a certain point but the longer you put it off the more maintenance you're going to have to do eventually and the more it's going to cost you eventually not to mention that the vehicle itself becomes a little less reliable and a little less usable. It's no different with ships so in canceling these maintenance periods we're going to have to get that maintenance done at some point in the future and that in itself is going to affect the operating schedule of that ship and that crew and it so it affects readiness further on down the line in ways that that we can't even fully predict right now.
