That's a very good question. I think this is where, in setting up the projects, it's very critical how you break them up. A big part of the initial stage is investment, but a big part of the downstream investment should be fed by the benefits you garner in the early years. That's why the breaking up of projects is also critical from a purely financial metric point of view.
A project is not just the work. It has to embody the financials with it. If it is generating some financial benefit in the first two, three, or four years, that net benefit should go towards the investment of future years. I don't see it as a 20-year investment and your payback starts on the 21st year, or a 10-year investment with payback in the 11th year. If I were looking at this, I would look at it in a slightly different way. How do I break it up so that at some point my surplus, so to speak, funds the future investment?
