Pension Liability
The shortfall on a defined benefit scheme, being the obligation less plan assets. Treated as a debt-like item in the EV bridge, usually net of the tax relief available on future contributions. Can dominate the bridge for older industrials with legacy schemes, and is highly sensitive to the discount rate used to value the obligation.

Where pension liability sits in the three statements
- Net pension deficit: £100m → £175m
- Reserves (remeasurement, OCI): −£75m
- Contributions paid (operating): set by the trustees
What moving it does
A scheme with obligations of £500m and assets of £400m, a deficit of £100m, a duration of fifteen years and a 25% tax rate. The discount rate falls by one percentage point.
| Statement | Line | Effect |
|---|---|---|
| Balance sheet | Obligation | Rises about 15%, £75m, to £575m. Fifteen years of duration times one point. |
| Balance sheet | Plan assets | Unchanged at £400m if they are equities and property. Bonds of matching duration would have risen with the obligation; that is what liability-driven investment is for. |
| Balance sheet | Net pension deficit | £100m to £175m. |
| Balance sheet | Reserves | −£75m through other comprehensive income. The remeasurement never reaches net income under IAS 19. |
| Income statement | Net income | Unchanged this year. Next year’s net interest charge changes, because it is the deficit times the discount rate: a larger deficit at a lower rate. |
| Cash flow statement | Contributions | Unchanged until the next triennial valuation, when the trustees will ask for more. |
| Balance sheet | Net debt, for the bridge | Deficit £175m less 25% tax relief on future contributions: £131m, up from £75m. |
The close. Liabilities rose £75m and equity fell £75m through reserves, so the balance sheet balances without a single entry in the income statement or the cash flow statement. That is the feature to explain: the largest movement in the company’s net worth this year did not go through profit, did not go through cash, and will still have to be paid.
What the footnote discloses
In the note
- The reconciliation of the obligation and of the plan assets from opening to closing: service cost, interest, benefits paid, contributions, actuarial changes, asset returns.
- The assumptions: discount rate, inflation, salary growth, mortality tables, and the sensitivity of the obligation to a change in each.
- The asset allocation: equities, bonds, property, insurance buy-ins, and how much is matched to the liabilities.
- The agreed contribution schedule, which is the cash the company has committed to pay, and the date of the next funding valuation.
What an analyst does with it
- Put the after-tax deficit in the enterprise value bridge, and say whether you used the accounting deficit or the funding deficit from the last triennial valuation, since the trustees’ number is usually larger and is the one that sets the cash.
- Use the sensitivity table to size the risk in one line: the deficit at plus and minus one point on the discount rate is the range a bidder has to be comfortable with.
- Compare contributions with service cost. The excess is deficit recovery, a debt repayment that sits inside operating cash flow and should be treated as one.
- Check the asset allocation against the liability duration. A scheme in unmatched equities is a leveraged bet on rates that the shareholders are funding.
The interview question it becomes
- “Where does a pension deficit go in an enterprise value bridge, and why?”
- In net debt, as a debt-like item, net of tax. It is a fixed obligation to pay cash to people outside the business, and shareholders only get what is left after it. Net of tax because the contributions that close the deficit are deductible, so the cash cost is the deficit times one minus the tax rate. For a £175m deficit at 25%, £131m.
- The follow-up: “Why not the gross number?”
- Because the company will get tax relief on every pound it pays in, and the bridge is supposed to be cash. The gross figure overstates the claim by the tax rate. The second catch is the reverse: some candidates net it off but use the accounting deficit when the trustees’ funding valuation, which actually sets the contributions, shows a larger one. The strong answer names both figures and says which the cash follows.
Why Pension Liability matters in interviews
For an older industrial, a utility, a bank or a former state company, the pension scheme can be the largest single item in the enterprise value bridge and the most volatile number on the balance sheet, moving by hundreds of millions on a change in a discount rate that nobody in the business controls. Interviewers ask about it because it tests whether you can read a note, tax-effect a liability, and explain why an obligation to pay pensions in 2050 belongs in a valuation today.
How it works in practice
A defined benefit scheme promises a pension based on salary and service; the company bears the risk that the assets set aside will not cover it. The balance sheet shows the net position: the present value of the obligation less the fair value of plan assets. A deficit is a liability, a surplus an asset, subject to a ceiling on how much surplus can be recognised.
The obligation is a present value, discounted under IAS 19 at the yield on high-quality corporate bonds of matching duration. A scheme with a fifteen-year duration sees its obligation rise roughly 15% for each one-point fall in that yield. The assets, if they are equities and property, do not move with it. That mismatch is the deficit’s volatility.
The income statement carries the service cost (the pension earned by staff this year, in operating costs) and a net interest charge on the deficit (in finance costs). Remeasurements, the actuarial gains and losses from changed assumptions and the gap between expected and actual asset returns, go through other comprehensive income and never touch profit. Under US GAAP they can be deferred and amortised into profit through the corridor method, which is one reason IFRS and US GAAP pension numbers are not comparable.
Cash is the contributions the company actually pays, which are set by negotiation with the trustees and the regulator, not by the accounting charge. A company can show a modest pension expense and be paying three times that in deficit recovery contributions, or the reverse.
What candidates get wrong
- Adding the gross deficit to net debt. Contributions to close it are tax-deductible, so the after-tax deficit is the cash cost, and that is the number for the bridge.
- Reading the service cost as the cash cost. The cash cost is in the note, under contributions, and for a closed scheme in deficit it is usually far higher.
- Treating a surplus as an asset the company can use. Trustees control it and the recognition ceiling limits what the balance sheet shows.
- Ignoring the sensitivity table. A deficit of £100m with a duration of eighteen years is a different risk from one with a duration of eight.
Pension Liability: frequently asked questions
What is a pension deficit?
The amount by which the present value of a defined benefit scheme’s promised pensions exceeds the assets set aside to pay them. It is shown net on the balance sheet, is highly sensitive to the discount rate used to value the promises, and is closed over time by contributions the company negotiates with the scheme’s trustees.
Why is a pension deficit treated as debt?
Because it is a fixed obligation to pay cash to people outside the business, and the cash to close it will not be available to shareholders. It goes in the enterprise value bridge like debt, net of the tax relief the contributions will attract, so that equity value reflects what is left after the pensioners are paid.
How does a change in interest rates affect a pension scheme?
A fall in high-quality corporate bond yields raises the present value of the obligation, by roughly the scheme’s duration in years times the change in the rate. Unless the assets are bonds of the same duration, the deficit widens by most of that amount, and the increase goes through other comprehensive income rather than profit. Rising rates do the opposite, which is why many schemes moved from deficit to surplus in 2022 and 2023.
