Offsetting Benefits

[Guest Sabadee!]

A plan provides for suspension of benefits for retirees upon reemployment. A retiree returns to employment and benefits aren't suspended until after 6 months. A SOBN will now be issued prospectively. The regs indicate future payments may be offset up to 25% for payments made while he was back in service. If the SOBN notice includes the information about the offset, are we good to gowith offsets once benefits recommence OR did the SOBN have to precede the period for which the offset will apply?
