I think there are committed costs that have already been incurred. There's a commitment right now—or at least there was at the time of the audit—to purchase four aircraft and then parts for eight others, long-lead parts. I don't know if that's progressed since then. Obviously that would be committed, but then the nation-to-nation agreement would have to change, or Canada would just not call up the rest of the planes. I think that's something National Defence could help you better understand.
