Thank you for the question, Mr. Chair.
What you're referring to is actually common to a number of our fleets. The process involves joint user groups, normally within NATO. What we do deliberately is to minimize the customization and Canadianization.... The members of the joint user groups share modification costs—in many cases, it's the software upgrade costs—amongst all the participants.
The second part of your question was whether or not we know exactly what we save. We don't know specifically what we would have paid for a change to the aircraft when we initially buy it, because we do not negotiate that different price. We're not interested in that different capability, so we don't negotiate that. Over time we could make approximations of what our interim support savings would be, but again, compared to what? Making comparisons to something you didn't do makes it fairly difficult.
Lastly, we don't report those speculative estimates to Parliament. We don't.
