What I would say in response to that, MP Lobb, is that we always, wherever possible, want to have competitive processes in place. We know that when we can have competitive processes in place, we are going to get the best value because of the competition. That's what competition breeds. It breeds bidders to bring in the best price they can because they know they're competing for the job.
I would say that there are some instances where we are not able to do that. For example, with the systems we have, there isn't compatibility in order to allow that. That, I think, I will turn over to my officials, because you have given specifics. They could respond to the specifics that you've cited.
