Sir, I think in every case, with these particularly complex procurements, we manage them within the envelope, but also would in fact return to government, as a policy question, to say: given the economic realities beyond our control, here were the assumptions going in, here's how we established the budget, there has been a significant increase in commodities and things have happened—which has occurred to us in the past. We would come forward with a question: do you want us to proceed within the existing budget, meaning fewer ships, less capability within a given ship, or do we want to revisit the budget allocation to continue forward?
It would really depend on, I would say.... If the degree of change is such that the contingency that we have established is insufficient, we would bring that back for decision to see from a policy perspective what the desired way forward is.
