The charges related to these trackers - or perhaps better named "followers at a distance" - are now highlighted as an ex cash expense. They used to be part of the murk of the dividend charges. In my view a good thing to see so clearly now what they are.
Given that the only stupid questions these days is the question not asked I am going to ask Sygnia exactly what their contractual rights to this charge are and how it is determined and whether it can be varied at the instance of themselves.
