This posting by Jeffrey Keminar on Milliman’s Retirement Townhall blog poses the question of whether plan sponsors should consider a permanent window that would allow terminated vested defined benefit participants to take a lump sum distribution. Advantages cited include no longer have to pay PBGC premiums for participants who take the lump sum and alleviating concern at a future date about trying to locate a participant. ┬áThe posting also highlights potential downsides as well as plan administration and compliance responsibilities associated with this strategy.
