You didn't say what his payout options are but it sounds like he is receiving a reduced benefit in order to pass on spousal benefits after he dies. If he were to take the option of receiving maximum benefits now, when he dies you would receive nothing.

WHEN WE SEND PAPERWORK IN, OPM WILL BEGIN DEDUCTING ADDITIONAL $15.00/mo until about $3K has been deducted for just electing the survivor benefit. In addition, every month, the annuity payment that he receives will be reduced by approx $220. for choosing to pass on the maximum survivor benefit. He could elect to pass on less, any amount he chooses, with proportionally smaller monthly reduction.

If you could get out a crystal ball and predict when he dies, you may come out ahead by investing the additional $220/month if he lives a long time. But there are many stories of people dying right after retirement without ever collecting their first check.

YES, THE CRYSTAL BALL PART IS THE MYSTERY. He is looking for new job, and doesn't have lack of interests problem that causes some people to feel their lives have stopped, which is wonderful. His is beginning again, smile. thanks!
