definition

a mechanism in an ESOP under which a percentage of unvested options immediately vest (i.e. accelerate) on an exit, where the vesting of the unvested options is conditional on a second event occurring. The second event is typically an employee being terminated, or that employee resigning with good reason within a certain time period after the exit event. Whilst commonly adopted in US investment documents, double trigger acceleration is less commonly used in ESOPs for Southeast Asia startups.
