I have a participant who worked, termed, took a lump sum, but was then rehired. The plan docuemnts says that for benefits for someone who took a lump sum you use all service and then reduce that amount for the actuarial equivalent of the lump sum.
1) What happens if the benefit we calculate for this person using post lump sum payout service is greater than the amount we would get if we use total service and deduct the lump sum?
2) If the lump sum was paid out in 2000, do we have to go back to 2000 and figure out the AE definition at that point to redice the annuity? Or, can we simply take the lump sum paid out and reduce the current benefit? Or, take the annuity benefit and convert to a lump sum using current assumptions?
Thanks,
