Ann: H1 FY2018 Results Announcement, page-7

I'm confused by the 3 fold increase in Tax obligations which has dragged the NPAT into negative territory and hence the lower EPS.
I'm not great with the structure of Withholding tax & exchange rates etc which is touted as the reason, but it obviously relates to OS earnings which is also why there's no franking attached to the dividend.
Another point is somehow the increased tax obligations arise, apparently, from the special dividend.
Again I'm confused.
Obviously I'm no accountant.

Not sure where I sit with the 1/2 year although the 2 recent announcements may well push rev's above full year forecasts assuming they weren't included in managements forward guidance.
The share buy back I guess is good but is it the best use of cash?

Mmm I remain confused.
