45-04-08-02.1. Application of the 2012 IAR Mortality Table.

In using the 2012 IAR Mortality Table, the mortality rate for a person age x in year (2012 + n) is calculated as follows:

$$q_x²⁰¹²⁺ⁿ = q_x²⁰¹²(1-G2_x)^n$$

The resulting $q_x²⁰¹²⁺ⁿ$ shall be rounded to three decimal places per 1,000 (e.g., 0.741 per 1,000). Also, the rounding shall occur according to the formula above, starting at the 2012 IAM Period Table rate.

For example, for a male age 30, $q_x²⁰¹² = 0.741$

$$q_x²⁰¹³ = 0.741 * (1-0.010) ^ 1 = 07.73358, \text{ which is rounded to } 0.734.$$

$$q_x²⁰¹⁴ = 0.741 * (1-0.010) ^ 2 = 0.7262541, \text{ which is rounded to } 0.726.$$

A method leading to incorrect round would be to calculate $q_x²⁰¹⁴$ as $q_x²⁰¹³ * (1-0.010)$, or $0.734 * 0.99 = 0.727$. It is incorrect to use the already rounded $q_x²⁰¹³$ to calculate $q_x²⁰¹⁴$.
