It was a combination of all factors. We are an independent crown corporation employer, so we have employment agreements in place with all our staff. I'll answer it three ways quickly.
Attrition, that's a quick one to address. In some cases, yes, it was a result of retirements and otherwise. In other cases, I've mentioned that we often use term positions. Where we see a need for a one- to three-year requirement, we will staff them with term positions and also draw on resources elsewhere in the country. It doesn't mean that we have to physically move the people. We operate very effectively that way.
Then you're right that there was a dramatic downturn in the DND infrastructure program. We went through a workforce adjustment, which we did in accordance with the terms of our employment agreements. A number of the positions were terminated, which we handled respectfully and fairly and with the proper legal advice. We're not mired in litigation coming out of that. We did it the right way, but we have to respond that way because, as I said, we're not an appropriated entity.
