Exercise Window


An exercise window is the period of time defined by a company that an employee may sell their vested stock options upon leaving that company. For example, if your company has a ten-year exercise window, then you will be able to sell your stock options for ten years after you have left. If you have not sold those stock options within ten years, then you forfeit your ownership of those vested stock options.
