Past Service Liability

Definition

Past Service Liability is the obligation or liability that arises to fund an employee’s accrued benefits in a pension plan for the period of service that occurred before the pension plan was instituted or before the employee became a member of the plan. It is an essential component in the actuarial evaluation and financial planning of pension schemes, as it factors into the total cost of the pension plan.

Examples

Corporate Pension Plans: A corporation sets up a new pension plan. Employees who have been with the company for 10 years before the plan’s establishment must have their previous 10 years of service factored into their pension benefits.
Public Sector Pension Plans: A government entity enacts a new pension program for its employees, which includes crediting service years for employees who have been serving before the program’s initiation.
Union Pension Plans: A union negotiates a pension plan that includes recognizing all previous years of service for its members who were employed in their respective trades but were not covered by a pension plan before its establishment.

Frequently Asked Questions
