Combined Top Heavy CB/DC - Gateway?

[Dougsbpc]

I see there was a question somewhat like this recently posted. However, it is not completely the same.

Suppose you have an employer who sponsors a cash balance plan and a safe harbor 401(k) Plan. The plans are top heavy and the 401(k) plan provides a safe harbor match. Both plans would pass 401(a)4 and 410(b) combined testing.

The top heavy minimum is 5% and provided in the 401(k) plan.

The non-elective employer contribution in the 401(k) plan requires 1,000 hours and last day. The CB plan only requires 100 hours to accrue a benefit.

There is a non-key NHCE who terminated employment in 2018 with 400 hours of service. She is covered under both the 401(k) plan and Cash balance plan.

Must she receive a 5% top heavy minimum in the 401(k) plan since she did accrue a benefit in the CB plan? Then must she receive the 7.5% gateway as well?

Thanks.
