newb: question
Hoping someone can help.

Just looking at this report and was hoping that someone could clarify a point for me (a new person at reading these reports).
My understanding is that we have approx 37.5Mil shares on issue and there are another 40Mil outstanding shares that are available as option currently on the books. Is this correct?
If so that's a huge dilution of share holder value?

Are there performance requirements attached to these options?

Any info would be appreciated!
