At Irving we are only responsible for a component of the total cost of the Canadian surface combatant program. We periodically send our projections for estimates of the cost, but these are focused primarily on the construction of the ship and some of the combat systems. They do not include, for instance, infrastructure. They do not include equipment that is being purchased through a foreign military sales program. They do not include training. There are a lot of costs that are rolled in there that don't fall under Irving's responsibility.
