The computation points for DIB computations are:

• •

  NH has not attained age 62: date of DIB onset.

• •

  NH has attained age 62: date of actual age 62 attainment.

• •

  Period of disability is not considered: earlier of the assumed or actual age 62 month.

   The NH is assumed to attain age 62 in the first month of the DIB waiting period. If there is no waiting period, NH is assumed to attain age 62 in the first month of DIB entitlement.

The PIA for DIB is computed as if the NH became entitled to RIB in the first month of DIB entitlement.
