Long term incentives

Hi sir, when it comes to long term incentives such as share options and performance stock units (company shares), am I right to say the following ? Both should be subject to meeting performance targets Share options should have a vesting scheduled attached, whereby, only a certain number of options can be exercised each year.Otherwise, it can result in short termism practices. Performance stock units(company shares) may be awarded with limits on their transferability for a set time. Otherwise, it can result in short termism practices. Example : The director can only sell the shares when they retire.
