We saw two opportunities there to mitigate the cost risks associated with this decision—not necessarily added costs, but the mitigation of cost risks. One of them is to bring the efficiency of JSS 1 into JSS 2 by giving the engineers enough time to do the design changes and to incorporate them into JSS 2, and another to avoid rushing into the construction of the offshore oceanic science vessel, which required more design maturing before the start of construction. We were worried about entering construction without a mature enough design, which would otherwise have actually driven costs up.
