The first Arctic offshore patrol ship will be delivered into the navy next year. It will start to require some maintenance at that point, and every nine months thereafter will be a follow-on ship. The need to start providing maintenance is merging. At this point we've laid out a contract to make sure that it's not like past practices, which would have us at times delivering new fleets—aircraft, armoured vehicles, or ships—and then establishing in-service support contracts for people after the fact. The approach we're taking here has enabled us to bring in the suppliers who perform the maintenance so that they can actually see what's happening up front.
It is a small amount of overhead. I don't have the exact numbers with me right now, but payments will start this coming fiscal year to enable them to be ready once the first AOPS comes into service. Beyond that, for the first five years, because we won't dock a ship until five years into life, it will be largely what we call “second-line”, or second-level, maintenance. We don't have the exact numbers with us. We can look at providing what the cash flow is and what the expectations are of the first five years of that contract.
