There are a number of questions there, but I do appreciate the member's offer to help me on this.
We'd have to go back to the action plan, but I believe that in 2010 we undertook to develop appropriate methodologies to life-cycle costs. We are in the process of developing those methodologies.
I would say just one thing—and the CFO may want to speak to this in response to a question. There is a difference—and I think people get a little bit confused—between the total cost of ownership of something and the life-cycle cost of a project or acquisition. So it is accurate to say that we agreed to address the methodological issues following the 2010 report, but we also acknowledged in our management action plan that it would take us time to develop those methodologies. Life-cycle costing is not a simple issue.
