Glossary Double-Trigger Acceleration

Double-trigger acceleration applies to shares subject to vesting. With double-trigger acceleration, any unvested shares are accelerated upon an acquisition or other change of control event (first trigger) and the termination without cause or resignation for good reason by the holder within a certain time period (e.g., 12 months) following the change of control (second trigger). Double-trigger acceleration is more commonly granted to startup founders and employees than is single-trigger acceleration.
