We have been told that FIOS will generate positive cashflow sometime in 2010.
Positive cash flow by 2010 probably makes sense. All they need to do is keep their CAPex down so that it is exceeded by EBITDA (less taxes).
Once they start making positive cash flow, then they can start "paying off" the early years when they were negative cash flow, and when they reach that, that's when they can declare payback. That'll be a fair period past 2010. The rest after that is ROI.
