Employees receive options to buy stock at a pre- determined price as a reward for a job well done. In a lot of cases the option costs the employee nothing. Unfortunately, many employees do not keep track of these options and the options either expire or employees fail to exercise their options at the right time.

It is important to find out how your stock option plan is structured and how you should take advantage of it. It is also important to understand the tax implications of these programs.

Unfortunately, these plans are unique to the company that you work for. So, to try to describe them here would be a difficult task.
