What exactly is a successor plan?

[BG5150]

I have a plan that is terminating. And I understand that a successor plan cannot be in place for at least a year after the assets of the first plan have been distributed.

However, what type(s) of plan might a successor plan be? Just a 401(k)? Could they put in place a PS plan? SIMPLE? SEP? SEP IRA?

It's now called an "alternative defined contribution plan", which would include a PSP or MPPP. But, an alternative defined contribution plan does not include an ESOP, SEP, SIMPLE IRA, 403(b) or 457(b) or (f). (Treas, Reg. Section 1.4019k)-1(d)(4)(i).)

Actually, you could put a new PSP or MPPP or 401(k) plan in place, but it just means that a distribution of elective deferrals due to termination of the terminated 401(k) plan is not permitted.
