A Safe Harbor Plan is amending eligibility from elapsed time to hours of service to trim out the part-timers. Anyone who has already met the elapsed time requirement must be permitted to enter the plan, but anyone who has not yet met the elapsed time requirement by the time the amendment goes into effect will be required to meet the 1000 hr/12 month rule.
My understanding is that, unless the employee moves into a class of employees that is defined by the plan as excludible by definition, once you're in, you're in. As an employee who has met eligibility requirements under prior eligibility rules, you may continue to participate in the plan, and you are therefore eligible to continue receiving the Safe Harbor contribution. This is being questioned, and I can't find any information that confirms or denies my assumption.
Thank you!
