Key Assumptions in Pension Actuarial Valuation

Introduction

A pension is a regular payment paid by the employers of the organization to its employees after his/her retirement. This acts as a liability for the employers and he needs to set aside a portion of his funds to be paid later on. Thus, pension actuarial valuation refers to evaluating the estimates how much the company should set aside for the future in order to pay pensions to its employees. 

Now, to evaluate pension actuarial valuation, actuaries design models based on statistical techniques, judgements and data available to them with reference to the employees in the organization and general future predictions published by trustable sources. While evaluating pension actuarial valuation, several key assumptions must be considered, some of which are discussed below in detail. 

Key Assumptions used in Pension Actuarial Valuation 

DEMOGRAPHIC ASSUMPTIONS: 

Demographic assumptions refer to the assumptions based on the behavior of the humans for whom plans are being made. Different types of demographic assumptions need to be evaluated for different measurements. These demographic assumptions are based on historical data suitable and with reference to the pension plans so formed.

Some of the demographic assumptions include: mortality rates, employee turnover rate, retirement rate, dependent assumption rate, etc.

1. Employee Turnover Rate: 

This rate reflects the number of people leaving the organization without claiming full pension benefits. It is essential to determine this as it gives a clear idea of how much to set aside today with reference to the number of people staying back or leaving the company, hence increasing or decreasing the future obligations of the company respectively.

2. Mortality Rate: 

Mortality rate is essential to predict the number of people dying due to an underlying cause. It helps actuaries to forecast how long the pensions would be paid in the future, helping them predict the liabilities more accurately. Mortality rates are calculated mostly with reference to the mortality table provided, with reference to the data for whom this is calculated as factors like age, gender, profession, etc. play a major role in this. Since, there are changes in the mortality data and the trends today have changes slightly, revising these mortality rates is crucial. 

3. Retirement Rate: 

This assumption is essential as it clears after how many years the person will retire and hence pensions to be paid as a part of pension actuarial valuation. This must be followed according to the rules of the company and also according to the general rules set by the government, depending on the type of the company. Early retirement increases in the payouts to the employees, and vice versa, thus impacting the required funds of the company. 

4. Dependent Assumption rate: 

This rate determines whether or not the retired employees have another being dependent on him/her to whom the benefits must be provided after the death of the employee. This plays a major role in determining the future obligations of the company along with the evaluation of mortality rate and retirement rate for accurate pension actuarial valuation.

ECONOMIC ASSUMPTIONS: 

Economic assumptions play a vital role in evaluating pension actuarial valuation. They reflect the assumptions based on future economic as well as financial conditions, influencing the pension actuarial valuation. Some of these assumptions include discount rates, salary escalation rate, inflation rate and investment return rate. These are discussed in detail below. 

1. Discount Rate: 

It reflects the time value for money and plays a crucial role in determining the present value of liabilities to be paid in the future. This is determined with reference to the market yields, any fluctuation in which would impact the rate of discount set earlier and hence the pension actuarial valuation may differ. Discount rates must be evaluated after repeated observation otherwise there may be cases of

underestimation or overestimation of funds. 

2. Salary Escalation Rate: 

This refers to making an estimation of the growth in the salary of employees in the near future and basing our estimates to determine the funds required to fulfill future obligations. There is a positive relation between discount rates and salary escalation rates since increase in both of them is dependent upon the inflation likely to arise in the economy in future. Also, salary escalation rate should also be determined on the basis of past as well as present circumstances, company’s long-term goals should not be missed while estimating these. 

3. Inflation Rate: 

This rate reflects the assumptions based on expected increase in the general price level relevant to the pension actuarial valuation. This has a direct impact on the 

adjustment of benefits as well as on the investment returns, thus correct estimation is necessary so that the pension valuation matches with the future circumstances. 

4. Investment Return Rate: 

This rate determines the expected return on the ongoing or future projects of the company so that accurate evaluation is made regarding the benefits enjoyed by the company, and hence on the required funds so that these future obligations can be met without any pressure on its finances. 

Conclusion 

Hence, to sum up, we conclude that for pension actuarial valuation, correct estimation of the above-mentioned rates is crucial. This promises the company the fulfillment of employment benefit schemes to be provided in the future without adversely affecting the finances of the company, hence maintaining its longevity in the long run. 

Frequently Asked Questions

1. How often should the pension actuarial valuation assumptions be reviewed or updated? 

The pension actuarial valuation assumptions must be updated annually, or more specifically when there are changes in demographic, economic or any other factors influencing these rates. 

2. Who is responsible for determining these pension valuation assumptions? 

Technically, the pension actuary must determine the key assumptions required to estimate the future obligations with reference to the pension plans since they can better evaluate the key factors based on past data, present scenario and expected future circumstances. 

3. Can pension plan sponsors affect or influence the pension actuarial valuation assumptions? 

Though only the actuaries have the right to set these assumptions, pension sponsors can most definitely provide significant and relatable data, based on which these assumptions can be made more precisely.

4. What would happen if the pension plan is underfunded?

If the pension plan is underfunded, i.e. there is shortage in the funds set aside to fulfill the pension plans to be provided in the future, this means that our assumptions were not accurate and hence the finances of the company suffer. The company may suffer losses, accumulation of which over years impedes the financial health of the company. 

5. How do the regulatory bodies set by the government utilize the pension actuarial valuation? 

These regulatory bodies regulate the company’s plans and ensure that they meet the guidelines and rules set by the government regarding the pension schemes to be provided, thus keeping a check on pension plans and supporting the present as well as retired employees of the organization.
