What is an Accumulated Benefit Obligation?

An accumulated benefit obligation is the present value of an employee’s pension, based on the employee’s accumulated work to date. The value of future changes in a person’s compensation is not considered; instead, it is calculated based on current compensation levels. Since a person continuing to work will likely experience several increases in pay over the term of his employment, this means that the accumulated benefit obligation is lower than the pension obligation that will eventually be payable to an employee.

Significance of the Accumulated Benefit Obligation

The accumulated benefit obligation can be a significant liability of a business, and so is inspected by an investor or lender as part of the due diligence process when examining the obligations of an organization. If the obligation seems low, a potential acquirer could reduce its bid for a business, on the grounds that the target company has not recognized the full extent of its pension liability.

Accumulated Benefit Obligation vs. Projected Benefit Obligation

The accumulated benefit obligation is the present value of a pension liability based on the accumulated work to date, while the projected benefit obligation covers the expected future work to be conducted by employees. When combined, these two values constitute the total pension obligation of an employer.
