Vested benefit obligation belongs in a plan-specific employer file. VBO measures actuarial present value only for benefits no longer contingent on future service. It uses the plan terms, participant data, and compensation embedded in the supported vested-benefit measure.

Apply it

A signed report may show VBO of $8.6 million, ABO of $9.4 million, and PBO of $11.2 million. The smallest amount is not incomplete; it answers the narrower vesting question.

Common mistake

Do not assume that vBO is the obligation used to measure pension funded status. VBO includes only vested benefits; pension funded status uses PBO and plan assets. That error would substitute a narrower analytical measure for the PBO used in pension funded status.

Keep the boundary clear

VBO does not use projected salary merely because PBO does. It supports vesting analysis and disclosure but does not replace PBO in pension funded status.

Authority

Read ASC 715-30-35-41 for measurement of vested benefits.
