Thank you for the question.
I can't give you a great explanation for that, so we'll have to get back to you on that. What I can tell you is that recruiting has been ramped up significantly in the last four years or so. The intake has been much greater. The volumes of people coming through basic training and then into trades training have gone up significantly. New investments have been made in that area, but I'll have to get back to you on a detailed explanation on that.
