What are unfunded pension liabilities, and how are they treated in an LBO?
A typical mid-market pension is a defined-benefit (DB) plan — the employer guarantees a set monthly benefit. On the balance sheet the DBO (defined-benefit obligation) less plan assets appears as a pension deficit.
Why relevant for LBOs? The pension deficit counts as a net-debt item and reduces the equity purchase price. Under IFRS (current market discount rate, IAS 19) the DBO is typically 30–50% higher than under local GAAP (a smoothed multi-year average). Sponsors must keep the two views separate.

| Item | Local GAAP | IFRS |
|---|---|---|
| DBO | $40m | $55m |
| Plan assets | $25m | $25m |
| Net pension liability | $15m | $30m |
The IFRS view shows the deficit twice as large — very relevant in lender negotiations and buyer audits.
- Buy-out to an insurer: transfer the pension to an insurer, typically 1.2–1.5x DBO in price
- Pension freeze: no new DB accruals, standard in PE-led targets
- Liability-driven investing (LDI): invest plan assets to move with the DBO, reducing discount-rate sensitivity
Question: "How much pension risk does your target carry?"
Answer: "DBO over EBITDA — above 2x it's a red flag for banks. Many mid-market industrial targets sit at 1.5–3x. On the IFRS view typically 30–50% higher than local GAAP. Mitigation runs through a pension buy-out to an insurer or a freeze for new entrants."
