Notes:
(1) Select-and-ultimate life functions

reflect termination due to death only. Select age denotes age last birthday at entitlement.
(2) The quantity

at duration 0 represents the assumed number of lives originally entitled to disability benefits at select age [ x ]; the quantity

at duration t represents the number of lives remaining from the original

lives as of attained age [ x ]+ t .
(3) Life functions are read across the row for durations 0-10, and down the ultimate column ("10+") for durations greater than 10.
(4) Values shown are based on the blended probabilities found in appendix table A.1A. See the appendix for details.
(5) See table 10C for attained ages beyond age 74.

(3) Life functions are read across the row for durations 0-10, and down the ultimate column ("10+") for durations greater than 10.
(4) Values shown are based on the blended probabilities found in appendix table A.1B. See the appendix for details.
(5) See table 10C for attained ages beyond age 74.
