Let me add that you raise an excellent point about the time at which you buy. One thing we try to do in all of our procurements is capture the span of existing technology that is proven and tried and also what's coming on the horizon but isn't at such a stage of research and development that there's lots of risk attached to it, so that when the actual contract is issued, Canada benefits from what is the latest in the market for which there's an established supply chain, so that we can get best value. That is the balance we try to strike, keeping in mind that it can take years to get to that stage.
