Thank you.
One point I want to carry on that was asked earlier by Mr. Braid is that when you have a new program coming out and you're looking at the estimates of what will be spent in a particular year, or the amount of spending, it's fair to say that you have to put that in context or perspective. That's simply because there's an application process that has to take place and there has to be some kind of a vetting process to accept a particular project. There must be a tendering process where you actually get contractors to bid on the project, and then there must be some work completed before you start getting invoices and payments are actually paid.
What's generally the lag time? What do you expect in terms of when a commitment is made in terms of how it compares to payments actually flowing across, when you're looking at how much is spent in a particular year? What's the context of all of that? Could you maybe deal with that for me?
