A benefit administrator needs to roll out a new plan to replace an existing plan to employees who have been with the company for 12 months. Employees who reach their 12-month length of service should get this plan on their anniversary. What type of event should the benefit administrator use to roll out this plan to employees in the U.S. benefit group?

A passive event is the appropriate mechanism for this scenario. Passive events are system-driven and do not require employee action. They can be configured to trigger based on specific criteria, such as an employee reaching a certain length of service. The event can automatically enroll the employee in the new plan and waive their enrollment in the old plan, effectively replacing it on their service anniversary date as required.

A. Open Enrollment is a time-bound period for all eligible employees to make elections, not for individual, date-specific changes based on service anniversaries.
B. A New Hire event is exclusively for newly hired employees and is not applicable to workers who have already completed 12 months of service.
D. A Worker Selectable event requires the employee to initiate the change. The requirement is for an automatic, system-driven rollout, not an employee-initiated one.
