TN 24 (09-02)
The WIB is computed by reducing the excess WIB by the RF for the WIB.
Compute the WIB as if the DIB PIA was being paid regardless of WC/PDB offset, EPE,
When the DIB ceases, the mode of reduction of the WIB depends on whether or not there
is entitlement to RIB. (See RS 00615.350 C.3)
The RIB is determined as explained in RS 00615.160. The prior DIB does not affect the RIB. If there are months of simultaneous RIB-DIB
entitlement, the RIB is given an ARF at FRA to eliminate months of DIB entitlement.
