Removing Auto Enrollment

[Gilmore]

We have a couple of clients that are going to add safe harbor to their existing 401(k) plan for 2019, and at the same time remove auto enrollment provisions.

Question is, what do we do with the current default enrolled participants.  Just continue to provide an annual notice each year until they either elect in, elect out, or terminate?

Or does eliminating the auto enroll provisions mean that their default deferrals should stop as of 1/1/19?

Thanks very much.
