Meaning
A contractual provision grants immediate ownership of shares that were originally subject to a time-based schedule. The implementation of cliff accelerated vesting occurs when a specific event, often a change in control, bypasses the remaining waiting period. This mechanism ensures that a founder or key employee receives their full allocation of equity before the original duration expires.
It stops applying once all shares are fully distributed or the underlying employment agreement terminates without a trigger.
Trigger Event
The movement of ownership shifts from a slow accumulation to a singular point in time. Because cliff accelerated vesting collapses years of service into a single day, the recipient gains liquidity much earlier than anticipated. This change requires the company to have sufficient authorized shares ready for immediate issuance.
The acceleration typically applies to the portion of the grant that would have vested over the subsequent twelve to twenty-four months.
Stakeholder Cost
Large blocks of stock move from the option pool to individual portfolios, which can affect the final purchase price during an acquisition. The company incurs a dilution cost when it honors cliff accelerated vesting during an exit. For the person receiving the benefit, the cost is often measured in future leverage, as they no longer have unvested shares to keep them tied to the new entity.
This redistribution of value changes the cap table permanently.
Vesting Boundary
Any early distribution of stock must be recorded on the official corporate record. This ensures that cliff accelerated vesting does not result in an over-issuance of shares. It remains dormant until a merger or sale meets the definition of a qualifying event.
