The WIB is computed independently when entitlement to reduced DIB-WIB is preceded by RIB. The RIB entitlement is controlling in determining the manner of reduction applicable at the initial MOET to WIB and at full retirement age. This applies even if the claimant is also entitled to DIB in the first month of WIB entitlement. The following example shows a computation when the N/H is simultaneously entitled to DIB/WIB after prior entitlement to RIB.

  

Example:

Jane Doe, DOB 03/04/1945 entitled to reduced RIB effective 07/2007.

  

DATE    PIA            RF    MBA

07/07      1259.00        44    965.20

DIB entitlement effective 12/ 2007.

  

DATE    PIA            RF    MBA

12/07      1287.90        5    1252.10

WIB entitlement effective 12/07 (preceded by reduced RIB).

   

DATE    UNREDUCED WIB    RF    MBA

12/07     1743.00                       39    $1473.90

Payable combined reduced HA-D effective 12/07 is:

 1473.90 -- Reduced WIB

-1252.10 -- Reduced DIB

   221.80 -- Difference payable as WIB

  

Subsequent increases in WIB continue to be calculated independently. If the DIB benefit is higher than the WIB benefit, see RS 00615.350B.2 . See also RS 00615.020 and RS 00615.150 for simultaneous and dual entitlement policies.
