Notes:
(1) Absolute recovery rate from the associated single-decrement model. Select age denotes age last birthday at entitlement.
(2) The quantity at duration t represents the number of recoveries per thousand beneficiaries during the (t+1) year of entitlement among those lives originally entitled to disability benefits at select age [ x ] and who are currently attained age [ x ]+t.
(3) Rates are read across the row for durations 0-10, and down the ultimate ("10+") column for durations greater than 10.
(4) The above rates are derived from the probabilities shown in table 8A. See the appendix for details.
