Eliminating Distribution Option after Termination Date

[Guest aciepluch]

Employer is terminating a profit sharing plan that provides for joint and survivor annuities. TPA is suggesting elimination of this distribution option to help speed things along. However, termination date has already passed. Can employer amend the plan to eliminate the JSA post termination date? I am aware of PBGC Reg. Section 4041.8, which would prevent this amendment to a terminated DB plan. Is anyone aware of any comparable guidance for DC plans?

Thanks in advance,

Amy
