ARM 6.6.5304. APPLICATION OF THE 2012 IAR MORTALITY TABLE

(1) In using the 2012 IAR Mortality Table, the mortality rate for a person age x in year (2012 + n) is calculated as follows: (a) q x 2012+n = q x 2012 (1-G2 x ) n ; (b) the resulting q x 2012+n shall be rounded to three decimal places per 1,000, e.g., 0.741 deaths per 1,000; (c) also, the rounding shall occur according to the formula above, starting at the 2012 period table rate. For example: (i) for a male age 30, q x 2012 = 0.741, q x 2013 = 0.741 * (1-0.010) ^ 1 = 0.73359, which is rounded to 0.734. q x 2014 = 0.741 * (1-0.010) ^ 1 = 0.7262541, which is rounded to 0.726. (ii) a method leading to incorrect rounding would be to calculate q x 2014 as q x 2013 * (1-0.010), or 0.734 * 0.99 = 0.727. (d) It is incorrect to use the already rounded q x 2013 to calculate q x 2014 .
