Explain defined benefit pension obligations and how they flow through the statements
The idea
A defined benefit plan promises a specified benefit, so the employer bears the investment and longevity risk. The balance sheet reports the funded status — the fair value of plan assets less the present value of the obligation — as an asset or liability, while service and interest costs run through profit or loss and actuarial gains and losses largely through other comprehensive income. The obligation depends on assumptions management sets: the discount rate (anchored to high-quality corporate bond yields), expected salary growth and mortality. A higher discount rate reduces the reported obligation without changing a single promised payment, which is why an analyst compares the assumed rate with peers and with market yields before accepting the funded status.
A practice question
What does the funded status of a defined benefit plan represent?
- The plan assets less the present value of the benefit obligation — correct
- The annual contribution made by the employerWhy not: A cash flow for the period rather than a position. A large contribution can accompany a plan still in deficit.
- The total benefits paid during the yearWhy not: Also a flow, and one that reduces both plan assets and the obligation without changing the net position much.
A surplus is reported as an asset and a deficit as a liability, which puts the net position on the balance sheet.
A harder one
What is the effect of assuming a higher discount rate on the reported obligation?
- The obligation risesWhy not: Backwards. A higher rate discounts the same future payments more heavily, which lowers their present value.
- The obligation falls, though the promised payments are unchanged — correct
- The obligation is unaffectedWhy not: The rate is what converts promised future payments into a balance sheet figure, so it drives the reported amount directly.
Discounting the same future payments more heavily reduces their present value. The economics of what the employees are owed do not change at all.
The hardest tier
Why does the employer bear more risk under a defined benefit plan than a defined contribution plan?
- Because defined benefit plans are unfunded by lawWhy not: Most are funded, often under regulatory minimums. Funding level is not what distinguishes the two arrangements.
- Because defined contribution plans have no employer contributionsWhy not: They usually do. The difference is that the employer's obligation ends once the contribution is made.
- Because the promised benefit is fixed — correct
Poor investment returns or greater longevity increase what the employer must fund. Under a defined contribution plan the obligation ends when the contribution is made; under a defined benefit plan the employer has guaranteed an outcome and absorbs every shortfall in reaching it.
