If RIB is reduced under Method II due to a prior entitlement to reduced WIB before age 62 (see RS 00615.160) and the person later becomes entitled to a reduced spouse's benefit, the spouse's benefit is computed without regard to the WIB and reduced RIB. Thus, when a RIB beneficiary with this type of reduction later becomes entitled to a spouse's benefit the RIB and spouse's benefit is computed without regard to the WIB entitlement. This is only to determine the amount payable as a spouse. Once the full reduced spouse's benefit is determined, the reduced RIB using Method II is subtracted from the full reduced spouse's benefit. The result is the amount of reduced spouse benefits due.
