I received my entitlement offer this morning but have not had a chance to read it. I was just browsing through the previous notice and it says unlisted options exercisable at .001
Does this also translate to our unlisted options??
What is the projected value of the unlisted options???
I need to be able to quantify some kind of projected value for these to weigh up buying back lower vs relinquishing my entitlement. I was able to sell my holdings before it fell back too far and am contemplating taking up the share offer. I am hoping for more information as to pros and cons to this.
Sorry if this information is in the letter received but as I said just dont have it here.. Could be a good topic anyway. Any thoughts appreciated.
