We have cost estimates for all the vessels.
One of the reasons, I think, as Mr. Vandergrift mentioned, there was logic in changing the sequence was to allow for the oceanographic science vessel...so we can mature the design to remove some of the risks. In fact, we can see a potential reduction in costs as a result of giving ourselves more time to mature that design and not try to push the team to try to finish two designs concurrently and very fast. The cost estimates are evolving, but we see mitigation on costs as we are trying to mature the design so we don't start production too prematurely.
