What Is Vesting in an Employee Share Plan?
Vesting is the mechanism used in some employee share plans to make shares conditional on continued employment. In vesting-based schemes, when an employee is allotted shares, those shares don't become unconditionally theirs immediately — they vest over time, typically three to five years. Note: not all schemes use vesting. Shares Saver administers direct ownership schemes where shares are purchased and registered unconditionally in the employee's name at each monthly purchase, with no vesting period.
Vesting (Employee Share Plan). Vesting is the process by which an employee's right to allotted shares becomes unconditional over time. Until shares vest, the employee cannot sell them and may forfeit them if they leave the company.
How vesting works
On the allotment date, shares are awarded to the employee and registered in a trust on their behalf. During the vesting period, the employee cannot sell the shares and may forfeit them if they leave (depending on the leaver provisions). On the vesting date, the shares are transferred out of the trust into the employee's direct CSCS account — they become the employee's unconditional property.
Cliff vesting vs graded vesting
Cliff vesting: all shares vest on a single date. For example, 100% vest after three years. If the employee leaves before year three, they forfeit all shares (bad leaver) or a pro-rata portion (good leaver). Graded vesting: shares vest in tranches. For example, one-third per year over three years. The employee always retains shares for time already served.
Performance vesting
Some Nigerian ESIS add a performance condition on top of the time-based vesting requirement. For example, a senior executive might receive shares that only vest if the company achieves a target earnings growth over the vesting period. This aligns management incentives with shareholder interests.
Good leavers vs bad leavers
Leaver provisions determine what happens to unvested shares when an employee departs. 'Good leavers' (retirement, redundancy, ill-health, death, or mutual departure) typically retain a pro-rata portion. 'Bad leavers' (voluntary resignation, dismissal for cause) typically forfeit all unvested shares. Vested shares always belong unconditionally to the employee regardless of the leaver category.
