Actuarial Assumptions
Definition
Actuarial assumptions are estimates of future variables used to calculate the likely costs of pension schemes and life assurance policies, thus setting the contributions and benefits for such programs. They play a crucial role in financial modeling for post-employment benefits and insurance operations.
Types of Actuarial Assumptions
-
Demographic Assumptions: Concern characteristics of employees, such as:
- Mortality Rates: The likelihood of death at different ages.
- Disability Rates: The incidence of disability among employees.
- Retirement Age: Expected age of retirement for employees.
- Employee Turnover: Rates at which employees leave the organization.
-
Financial Assumptions: Involve projections of economic factors, such as:
- Medical Costs: Projected costs of healthcare and treatments.
- Salary Growth: Expected increases in employee salaries over time.
- Discount Rate: The interest rate used to discount future obligations to present value.
- Inflation Rate: Expected rate at which prices of goods and services increase.
Importance
Entities operating defined-benefit pension schemes are required to disclose the actuarial assumptions used in measuring their pension obligations. This includes outlining the demographic trends and financial projections that influence the scale and timing of benefit payouts, as well as detailing the discount rate applied.
Examples
- Company A uses actuarial assumptions based on a discount rate of 3.5% per annum and a salary growth rate of 2% annually for its defined-benefit pension plan.
- Insurance Firm B calculates life assurance policy costs by assuming a 1% annual decrease in mortality rates and a 3% yearly increase in healthcare costs.
- Organization C incorporates demographic assumptions that its workforce will have an average retirement age of 65 and a yearly turnover rate of 5%.
Frequently Asked Questions
Why are actuarial assumptions important in pension schemes? Actuarial assumptions help determine the present value of future pension benefits. They ensure that sufficient contributions are made to meet future liabilities, maintaining the financial health of a pension fund.
What happens if actuarial assumptions are inaccurate? If assumptions are inaccurate, it may lead to underfunding or overfunding of pension schemes. This can affect the financial stability of the organization and the security of employee benefits.
Can actuarial assumptions change over time? Yes, actuarial assumptions are periodically reviewed and adjusted based on new data, economic changes, and evolving demographic trends to ensure accurate projections.
What is a discount rate in actuarial assumptions? The discount rate is the interest rate used to convert future pension obligations to their present value. It’s a critical factor in determining the present cost of future benefits.
Who sets the actuarial assumptions? Actuarial assumptions are set by actuaries, professionals skilled in assessing financial risks and uncertainties using mathematical and statistical methods.

2. Post-Employment Benefits: Benefits provided to employees after leaving employment, including pensions and other retirement benefits, relying heavily on actuarial evaluations to estimate future costs.
3. Discount Rate: An interest rate used in determining the present value of future cash flows or obligations, essential in calculating the liabilities of pension schemes.
