Sorry Pygmy, meant to get back to you the other day on this.
There were 550 shareholders in 2015 - there are 739 in 2016.
Seems they use a template setup for the Annual Reports. If you add up the "Number of Ordinary Shareholders" in the table on page 53 (2016 A/R), it totals 739. Looks like they forgot to change the 550 from last year's A/R.
