I suspect the largest shareholder with 6.06% reported in the presentation reflects that shareholder's various holdings as recorded on the share register and aggregated together to arrive at the 6.06%. No doubt, that person would have sent in a substantial shareholder notice to the company at the time the aggregate holdings went over 5% as required by law. I checked the 2018 annual report and it showed that at that time the largest shareholder was Troy Harry (pg 90). The UBS Nominees holding of 4.42% would be a single holding as recorded on the register. I think this helps give us more information about top holders.
