Double-trigger RSUs are RSUs that have an additional condition for vesting beyond the standard time-based vesting.
With double-trigger RSUs, two triggers must generally occur for the shares to vest: a time-based or performance-based condition and a landmark event, such as the company going public or being bought out in a merger or acquisition.
These two conditions must be met before the RSUs convert into actual shares in the company.
On the other hand, ordinary RSUs (single-trigger RSUs) are usually only subject to a time-based condition wherein the worker simply has to stay with the company for a specific amount of time for the RSUs to convert.
