RS 00605.230 DIB Dropout Years
When initial DIB entitlement is 7/80 or later, the number of dropout years used to compute DIB is determined under the 1-for-5 rule.
If there was ever DIB entitlement prior to 7/80 the 1-for-5 rule will not apply - regardless of whether an exclusion or non-exclusion computation is used.
In RIB freeze cases where the prior DIB entitlement was 7/80 or later and 1-for-5 drop-out applied to the DIB for any part of the 12 months preceding the attainment of age 62, the 1-for-5 rule is used for the RIB freeze computation as well. The RIB non-freeze computation will use the full 5-year drop out.
In survivor computations, the full 5-year dropout applies, including situations where the deceased NH was entitled to DIB based on the 1-for-5 rule.
1. Calculating 1-for-5 Dropout
To calculate a 1-for-5 dropout:
Determine the number of elapsed years (RS 00605.220 or RS 00605.225).
Divide the number by five, dropping any remainder.
Select the smaller of: the result in b. or 5. This is the DIB dropout years.
Subtract the number of dropout years from the elapsed years to equal the computation years.
NOTE: the minimum number of computation years is two.
2. Freeze and Non-Freeze Requirements Met
Make a separate determination of the 1-for-5 rule when the requirements for a freeze and a non-freeze computation are met.
