Deferred vested participant died after RBD. When calculating his actuarially-increased benefit (from NRD to RBD), the lump sum amount is below the Plan's threshold for a mandatory cashout. RBD was 4/1/10, DOD was 11/6/17. We've already established that his Estate is due the mandatory cashout, however, would interest need to be applied to that lump sum and if so, from RBD to death or RBD to distribution?
