Hi all, I am trying to work out what to do with some vested options in a private company I recently left. Specifically, I want to work out if I want to exercise all, some or none of the options. If I decided to exercise all, it will cost me approx $USD16000 so it's not a decision I take lightly. This is the information I have so far: the exercise price per option the number of vested options My preliminary research on valuing shares in private companies has not yielded much. This is my approach so far: find a company that is a similar size and that conducts similar business find the share price to earnings ratio of the similar company apply the price to earnings ratio of the target company work out if the exercise price is fair To follow this approach, the missing information I have identified is volume of shares in the company earnings information (not sure what document I should request to get that) Any comments on the approach or any additional information I need to make an informed decision?
