I think they would just use a price on a particular day. Not sure the day or if it should be opening or closing price.
I note that on Comsec the chart of PSZ looks like it has been corrected for capital distribution, so presumably there is some corporate action notice from ASX that has a figure to base this on. I assume we shall be notified in time.
I sold my tnt at 8c today, long term it is probably a buy, but at the moment I just see it as a company that has just bought a lot of stuff and needs time to digest and I needed to reduce my exposure from the extras I picked up in the capital raising and aftermath. Surely there has to be more than 3c left in PSZ!
