Vest means to become an entitlement. Under a share-based payment arrangement, a counterparty’s right to receive cash, other assets or equity instruments of the entity vests when the counterparty’s entitlement is no longer conditional on the satisfaction of any vesting conditions.
Vest is specifically discussed in IFRS 2 Share-based Payment.
