I think the Parliamentary Budget Officer has talked about that as well. We did mention that as you delay an acquisition, you lose $200 to $250 million of purchasing power. You just cannot avoid those inflationary pressures, so even though you might have given in 2006—let's just pick a date—$2 billion or $2.6 billion, which seems sufficient to produce that, it's not sufficient anymore.
I think we should also be quite honest with ourselves that part of the NSPS is to build those ships in Canada. There will be a premium of some sort that will be paid in order to start up or reanimate that industry. That's fine, because that's what we're there to do; the development of the nation is part and parcel of it. However, there is an erosion that we have to recognize either in capability or inflationary pressures by year, which diminishes either the capability that you put into a ship or the number of ships that you are going to acquire.
