LRB calc date if MRD is > DOT

[Guest SuzieQNEC]

For a participant who elects to defer RMD's until after termination. I understand that the age 70 1/2 benefit is actuarially increased until the actual late retirement date. Would that age 70 1/2 amount be calculated actually as of the date age 70 1/2, or the April 1 of the following year up through actual late retirement date?

Example:

DOB 1/1/30

Age 70 1/2 7/1/00

RBD 4/1/01

LRD 1/1/08

Would accrued benefit at 7/1/00 or 4/1/01 be increased and compared to benefit acrcrued at 1/1/08?

Another question, if this participant doesn't retire but would like to start receiving benefits at 1/1/08 and continue working, would his benefit be calculated as of age 70 1/2 and caught up, or could it just be started now. Participant did elect to defer back at age 70 1/2 and wants to change mind. Question is assuming plan doc allows this, since Plan Administrator wants to allow this, but not sure yet.
