IFRS 37 Provisions & Contingencies: Complete Guide with Worked Examples

By Usman Qureshi (ACCA, ACA) · Published July 2026 · Last reviewed July 2026 · 14 min read

IFRS 37 (Provisions, Contingent Liabilities and Contingent Assets) governs when to recognize a liability for future obligations (warranties, legal claims, environmental cleanup). The key question: is it probable you'll need to pay? This guide walks through the recognition criteria, measurement, warranty obligations, legal claims, and the audit red flags around over/under-provisioning.

In this guide

What is a Provision?

A provision is a liability of uncertain timing or amount. It's recognized on the balance sheet when three criteria are met.

Three Recognition Criteria (All Must Be Met)

  1. Present obligation: The entity has a legal or constructive obligation as a result of a past event
  2. Probable outflow: Probable that resources will flow out to settle the obligation
  3. Reliable estimate: A reliable estimate can be made of the amount

Key difference: If any criterion is NOT met, the item is a contingent liability (disclosed in notes, not recognized).

The "Probable" Test: Key Judgment

IFRS 37 defines "probable" as more likely than not (>50%). This is a judgment call auditors heavily challenge.

Examples: Probable vs Not Probable

Scenario Probable? Accounting
Product warranty: 60% of customers claim warranty Yes (>50%) Recognize provision
Legal lawsuit: 40% chance of loss based on precedent No (<50%) Disclose as contingent liability
Environmental cleanup: Regulation now requires remediation Yes (obligation exists) Recognize provision
Possible patent claim: Legal team unsure of merit Unclear (judgment) Disclose as contingent; auditors push to clarify likelihood

Measurement: Present Value & Expected Value

Measure a provision at the expected value of the obligation, discounted to present value.

Two Methods (Use Whichever Better Predicts the Outcome)

If settlement is >1 year away, discount the provision using a pre-tax rate that reflects the time value of money and specific risks.

Measurement Example: Warranty Provision
Sold 10,000 products with 2-year warranty (cost to fix per unit = £50).
Historical claim rate: Year 1 = 20%, Year 2 = 10% (total 30%)
Expected claims: 3,000 units × £50 = £150,000

Timing of payouts:
— Year 1: 2,000 units × £50 = £100,000 (no discounting needed)
— Year 2: 1,000 units × £50 = £50,000 (discount at 5% = £47,619)

Total provision: £100,000 + £47,619 = £147,619

Warranty Obligations

A provision is typically required for warranty claims, measured as the expected cost based on historical claim rates.

If a lawsuit is unlikely to succeed (<50% probability), it's a contingent liability (disclosed in notes, not recognized). If probable (>50%), recognize a provision at estimated settlement amount.

Worked Example: Environmental Cleanup

Scenario: Manufacturing plant contaminated soil. Regulator requires cleanup by 2028. Estimated cost: £2m.

Audit Red Flags

Red Flag 1: Under-Provisioning

Finding: Company has pending litigation with 60% probability of £5m loss, but made no provision (claiming "unlikely").

Auditor action: At 60% probability (>50%), recognize provision of £5m × 60% = £3m.

Red Flag 2: Over-Provisioning

Finding: Warranty provision assumes 50% claim rate, but actual historical rate is 15%.

Auditor action: Reduce provision to actual expected rate; release the excess to profit.

Red Flag 3: Absent Discount

Finding: £10m environmental provision, due in 5 years, but not discounted.

Auditor action: Apply present value discount (5% = £7.8m); adjust provision and finance cost.

Real-Life Case Study: Provision, Contingent Liability, or Nothing?

Scenario. A company faces three matters at year end: (1) a warranty on products sold, (2) a lawsuit it will probably lose (est. £600k), and (3) a lawsuit it will probably win.

  • Warranty: present obligation, probable outflow, reliably estimable → provision.
  • Likely-lose lawsuit: probable outflow → provision £600k.
  • Likely-win lawsuit: possible only → contingent liability, disclose only.

Takeaway. The dividing line is "probable" (recognise) vs "possible" (disclose) vs "remote" (ignore). A present obligation from a past event plus a probable, measurable outflow is what turns a risk into a booked provision, mere existence of a claim is not enough.

Consult a qualified accountant for your specific circumstances. Provisions for legal claims are particularly contentious and subject to large audit adjustments.
