Stock options, the offer of discounted shares in lieu of cash, were all the rage 18 months ago, when Internet start-ups and their high-technology brethren were desperate for talent but could promise only future riches.
As far as local taxation of an employee's stock options goes, it is mostly straightforward.
An employee who obtains a share-option as part of a remuneration package for employment is taxable on the difference between the option price offered and the market value of the shares at the time the option is exercised and the shares are obtained.
For example, if an employee has an option to buy a share for HK$10 and that option is exercised when the share price stands at HK$25, the HK$15 difference, or the benefit, is subject to tax.
The price of the share when it is actually sold, whether it falls or rises, is irrelevant.
If options are assigned or released for consideration instead of being exercised, a tax liability can also arise. Such transactions are effectively taxed as being exercises of the transaction.
