Full explanation
Overview
A company promises to pay pensions for decades after an employee retires. That promise has to be valued and put on the balance sheet today — as a single number, decades before most of the cash ever moves.
IAS nineteen covers employee benefits — everything from next month's payroll to a pension promise that pays out for thirty years after someone retires. Most of it is simple. One part is genuinely hard, and it's where almost all of this standard's complexity lives.
One standard
Four categories of employee benefit — three are simple, one is hard: short-term benefits, post-employment benefits, other long-term benefits, and termination benefits.
Quick treatment
Short-term: wages, paid annual leave, bonuses due within twelve months — undiscounted, recognised as the employee works. Other long-term: things like long-service leave, discounted but without the full complexity ahead. Termination benefits: redundancy payments, recognised when the offer can no longer be withdrawn.
Post-employment benefits are where it gets hard, and the fork is simple to state: who bears the risk if the fund underperforms, or people live longer than expected? Defined contribution — the employee does. Defined benefit — the company does. Everything difficult in IAS nineteen follows from that one sentence.
DC vs DB
Defined contribution: the company pays a fixed amount into a fund. Expense equals the contribution due for the period. No further obligation — simple, and it matches cash paid. Defined benefit: the company promises a specific future benefit, often tied to final salary. The company bears the investment and longevity risk, not the employee.
The DBO
The defined benefit obligation — DBO — is the present value of that future promise, discounted using a high-quality corporate bond rate. Plan assets — the pension fund's own investments — are netted against it. Net liability on the balance sheet equals the DBO minus plan assets.
Three components make up the defined benefit expense, and where each one goes is the most-tested idea in this standard. Current service cost and net interest go through profit or loss — the ordinary cost of running the scheme. Remeasurements — actuarial gains and losses, and returns above or below expected — go to OCI, never recycled back.
Year start
Meridian Ltd, opening position: DBO two million euros, plan assets one million eight hundred thousand — opening net liability, two hundred thousand euros. Current service cost for the year: one hundred fifty thousand euros, straight to profit or loss.
Two sides
Net interest: the same five percent discount rate applied to both sides. Interest cost on the DBO is five percent of the two million euro obligation, which comes to one hundred thousand euros. Interest income on plan assets is five percent of the one point eight million in assets, which comes to ninety thousand euros. Net interest to profit or loss: ten thousand euros.
The noise
Now the remeasurements, both to OCI. An actuarial loss on the obligation — a demographic assumption changed — forty thousand euros. And the actual return on plan assets came in at ninety-five thousand, five thousand euros above the ninety thousand already credited as interest income — a five thousand euro remeasurement gain.
Contributions
Meridian also paid one hundred sixty thousand euros of contributions into the fund this year — cash in, reducing the net liability directly, with no P&L or OCI entry of its own.
The roll-forward
Assume no benefits were paid out this period. Closing DBO: two million, plus service cost, plus interest cost, plus the actuarial loss — two million two hundred ninety thousand. Closing plan assets: one point eight million, plus interest income, plus the remeasurement gain, plus contributions — two million fifty-five thousand. Closing net liability: two hundred thirty-five thousand euros.
Add it up from the components instead, and it has to reconcile: opening two hundred thousand, plus service cost and net interest through profit or loss, plus the net remeasurement loss through OCI, minus the contributions paid — two hundred thirty-five thousand. Same answer, two different routes.
Immediate, in full
One more component, easy to miss: past service cost. If Meridian amends the plan mid-year — say, improving benefits for years already worked — the entire increase in the DBO from that amendment is recognised in profit or loss immediately, in full. It is never spread forward over remaining service, and it is never treated as a remeasurement.
Curtailment & settlement
Two situations override the ordinary pattern, and both hit profit or loss immediately. A curtailment — a significant reduction in the employees covered, like a plant closure. A settlement — the obligation is eliminated outright, like a lump-sum buyout. Ordinary remeasurements wait for OCI; these don't.
What must be shown
Disclosure: a full reconciliation of both the DBO and plan assets from opening to closing balance, the split of expense between profit or loss and OCI, the significant actuarial assumptions — discount rate, salary growth, mortality — and a sensitivity analysis showing the impact of a one percent change in the discount rate.
IAS 19 vs IAS 26
One distinction worth knowing: IAS nineteen is the EMPLOYER'S accounting for the promise. IAS twenty-six governs the PENSION FUND'S OWN financial statements — the trustee's accounts, showing plan assets at fair value and the actuarial present value of promised benefits. It's disclosure for the fund itself, and it doesn't change the employer's IAS nineteen numbers.
There's a tax angle too, and it mirrors what we've already seen elsewhere: a pension deficit or surplus creates its own deferred tax position, because the tax deduction usually follows contributions actually paid, not the expense recognised under IAS nineteen — another genuine book-tax timing difference, IAS twelve's territory again.
Legacy schemes
Where this matters most: mature economies with legacy defined benefit schemes — the UK, the Netherlands, Germany, Japan. Most NEW pension schemes globally are defined contribution, because it moves the risk off the employer's balance sheet entirely. Defined benefit accounting is increasingly a legacy-scheme topic — which is exactly why it still matters for anyone reading older companies' accounts.
Why skip P&L ?
Question: why do actuarial gains and losses skip the income statement entirely? Because OCI isolates year-to-year assumption noise — discount rates, mortality tables — from the underlying service cost, so profit or loss reflects how the business is actually performing.
DC ever complicated?
Question: is a defined contribution pension ever complicated? Rarely — the expense simply equals the contribution due. Almost all of this standard's complexity is specifically a defined benefit feature.
Real leverage
For investors, a defined benefit pension deficit is real leverage — often larger than the interest-bearing debt sitting on the same balance sheet. And because the whole obligation is discounted at a corporate bond rate, the deficit can swing significantly year to year for reasons that have nothing to do with how the business actually performed.
