A 401(k) plan sponsor formerly had only key employees eligible to participate, so top heavy testing wasn't an issue. The plan included profit sharing contributions.
Next year, a non-key employee will become eligible. To get out of top-heavy testing, they just want to cease profit sharing contributions, allowing only the elective deferrals and safe harbor NECs (safe harbor NEC provision for non-HCEs had already been adopted when the plan was first adopted, but was basically moot until now because there were no non-HCEs).
Under IRC 416(g)(4)(H), is the plan considered exempt from top heavy testing? Going forward it "consists of" only the elective deferrals and the NEC, although it contains "old" profit sharing contributions made during the prior era.
