The amount payable as a spouse will be the difference between the spouse's benefit
and the RIB.
Example: A beneficiary is entitled to a reduced spouse benefit of $450.00. She becomes
entitled to her own RIB. After reduction the RIB is $200.00. She will receive her
own RIB of $200.00 plus the difference between it and the spouse
benefit - $250.00. So her total benefit will still equal $450.00.
