Minimum distributions to participants for whom you lack sufficient inf

[EGB]

Defined Benefit Plan: States that payments won't be made at age 65 unless you elect to take the money (ie, deemed deferral until minimum distributions). What do you do when:

Vested term. reaches age 65 and does not return distribution forms; thus, deemed deferral; time comes for mimimum distributions; you do not have current info. on the participant (ie, participant terminated 10 years ago and you do not know whether the participant is married, and if so, the age of the spouse)to allow you to calculate the mimimum distribution and you cannot get participant to respond to your request for the info. (or, in some cases, you can't find the participant). What should you do? In the case of the participant who simply won't give you the information, do you simply warn them of the excise tax and not pay the min. dist.? What about the case of the missing participant?

I suppose in the case of the missing participant, after making diligent effort to locate the missing participant (e.g., participating the in the DOL program), you can segregrate the funding attributable to that participant's benefit in some type of suspense account, subject to reinstatement if the participant resurfaces. ????

Has anyone run into these problems? Any suggestions would be appreciated.
