Ann: Options exercise, page-10

Jessie, if you're talking about this, it says total on issue, not open interest.
So I take that to mean 222m was available at the issue 2 yrs ago but any number could have been exercised between then and now.

How does company issued options work differently? Isn't all options company issued? Does the company take the other side of the trade (eg at 1.3c offer)? I assume they issued the options and walked away with their working capital raising 2 yrs ago. If that's the case, who bought these options back then? sophos? and if not asx then where are these being traded?
