Vesting means the process by which the employee is
given the right to apply for shares of the company against the options granted to him.
Vesting can be either time based or performance based or a combination of time
and performance based vesting.
Time based vesting :
Options vest as time lapses irrespective of the performance of
the employee and/ or the company
Performance based vesting :
Options vest only if specified performance criteria are met. For example performance
conditions could be either related to individual performance, company performance
(top line or bottom line), department performance, total shareholding return
(Peer group benchmarking).
