Ann: Full Year Results Presentation - Year Ended 31 December 2017, page-2

"Recurring revenues" made up a very small percentage of total revenues in 2017, with the major amount coming from sales of existing windfarm projects. I cannot see any revenue figures for 2018 in this report, and am wondering where the the extra revenue will come from to keep up the revenue growth. Was there any indication in the prospectus? Should I be worried? Thanks for future contributors.
