Well, we have done a sensitivity analysis, should there be, for example, a one- or two-year delay in the construction of these ships. We have estimates for that, so if COVID really did end up delaying the construction of these ships, there's a sensitivity analysis that indicates how much this would mean in terms of cost increases.
It's true that the costs of materials have increased, but if the committee wishes us to revise our cost estimate, we can certainly do that.
