Actuarial gain or loss refers to the adjustments made to the assumptions used to value a corporation’s defined benefit pension plan obligations. These adjustments arise due to the changes in actuarial assumptions such as discount rates, salary growth, inflation rates, mortality rates, and other demographic factors. An actuarial gain occurs when the assumptions used in the previous periods overestimate the pension obligations, while an actuarial loss arises when they underestimate these obligations.
Types of Actuarial Gain or Loss
Financial Assumptions
Discount Rates: Alterations in the interest rates used to discount future pension obligations can lead to actuarial gains or losses.
Inflation Rates: Changes in expected inflation rates can also affect the valuation of pension liabilities.
Demographic Assumptions
Mortality Rates: Updates to mortality tables and life expectancy assumptions can cause actuarial changes.
Salary Growth Estimates: Revisions in the projected salary growth of employees will impact the valuation of pension obligations.
Historical Context
Actuarial science has evolved significantly over the centuries, with its roots tracing back to the ancient civilizations. Modern actuarial practices began solidifying in the 17th century with the needs of life insurance. With the advent of corporate pension plans in the 20th century, the role of actuarial gain or loss became a crucial part of financial reporting and management.
Applicability and Impact
Financial Statements
Actuarial gains and losses impact the balance sheet and income statement of corporations. According to accounting standards (e.g., IAS 19 and ASC 715), these gains or losses are recognized in other comprehensive income (OCI) and subsequently amortized to net income over time.
Pension Plan Funding
Adjustments arising from actuarial gains or losses can influence the funding status of pension plans, indirectly affecting a company’s contributions and cash flow.
Examples
-
Discount Rate Change: A company revises its discount rate from 5% to 4%, leading to a lower present value of future obligations. This results in an actuarial gain if previous assumptions overestimated the liabilities.
-
Mortality Table Update: Incorporating updated life expectancy tables increases the projected pension obligations, causing an actuarial loss.
Comparisons with Related Terms
- Pension Expense: The periodic cost of providing pension benefits, which includes current service cost, interest cost, and actuarial gains or losses.
- Defined Benefit Plan: A type of pension plan where the benefits are computed using a formula that considers factors such as salary history and duration of employment.
