It certainly is not one of the easiest estimates that we had to conduct, but neither is it the most difficult estimate that we came up with. We know that there are ships that are not the same mission and size, but we have comparators in other countries that have similar missions but different size, or ships that are of a broadly similar size, different mission, and by amalgamating these two factors, and looking at the Canadian recent experience with major ships procurement, we are fairly confident in our cost estimate.
