That's an interesting question. We looked at the impact of the delays on the cost of the program, and we found that every year of a delay, roughly speaking, adds about $2.5 billion to the total cost of the acquisition phase—development and acquisition.
However, with regard to the causes of the delays themselves, we don't have a clear answer to that. We focused on the costs and we rely on data that is provided to us by DND. We don't have a clear answer as to the causes of the delays.
I think that DND officials or the minister would be in a much better position to explain in greater detail the causes for these multiple delays.
