I know it's based on the sale cost minus original purchase price and if held for over 12 months then 50% of the gain is assessable and added to other income earned. For me, I would need stx price to be 60c if I took the stx offer and sold prior to 12 months for it to be the same profit as if I sold wgo on market at 38c, so not exactly double but alot higher just to be the same outcome. I encourage you all to do the calcs and use salary calculators to help if needed as capital gain is the same as salary just without the superannuation from a tax perspective.
