Okay.
Mr. Sokolsky, you talked about adjusting commitments to meet the requirements. I think one of the problems we face, just generally speaking now, is that those requirements are always changing so quickly. Especially in this day and age, the requirements seem to change. New threats are coming about that we weren't anticipating two years ago. How do you square that, in the sense that the requirements are always changing yet the commitments seem so long to take?
Mr. Byers mentioned how the icebreaker from 2005 is taking two decades. Have the requirements changed in the Arctic since that was originally thought out?
