SIGNIFICANT ASSUMPTIONS
We used the following key assumptions to measure the post-employment benefit obligations and the net benefit plans cost for the DB pension plans and OPEB plans. These assumptions are long-term, which is consistent with the nature of post-employment benefit plans.
(1) Cost of living indexation rate is only applicable to DB pension plans
The weighted average duration of the post-employment benefit obligation is 14 years.
We assumed the following trend rates in healthcare costs: • an annual increase in the cost of medication of 6.5% for 2019 decreasing to 4.0% over 20 years • an annual increase in the cost of covered dental benefits of 4% • an annual increase in the cost of covered hospital benefits of 3.7% • an annual increase in the cost of other covered healthcare benefits of 4%
Assumed trend rates in healthcare costs have a significant effect on the amounts reported for the healthcare plans.

Question: For post-employment benefit obligations, what is the percentage change in the life expectancy at age 65 in 2019?

((23.2-23.1)/23.1) * 100, therefore {"answer": "0.43", "scale": "percent"}
