Vesting refers to the waiting period before an earned financial reward is reaped. The vesting period should not see a change of status for it to lead to the reward. 


Vesting is most commonly used for equity share or stock options given by employers to their employees. The employees on being given the stock options at a deep discount as a reward for performance need to continue working at the company for a certain period of time, say five years, which is the vesting period, before being able to exercise the ownership of the stocks.
