What Are Contingent Liabilities?

A guide to contingent liabilities in UK accounting, covering the definition, recognition criteria, disclosure requirements, and their treatment under FRS 102 and the Companies Act.

A contingent liability is a possible obligation arising from past events whose existence will only be confirmed by the occurrence or non-occurrence of one or more uncertain future events not wholly within the control of the business. It can also be a present obligation where the amount cannot be measured reliably or where an outflow of economic resources is not probable.

Unlike a provision, which is recognised on the balance sheet as a liability, a contingent liability is disclosed in the notes to the financial statements but is not recognised as a balance sheet liability – unless it becomes probable that payment will be required.

Contingent Liabilities Under FRS 102

FRS 102 (Section 21) sets out the rules for provisions, contingent liabilities, and contingent assets. The treatment depends on the probability of the obligation crystallising:

Probability of Outflow Amount Measurable? Treatment
Probable (more likely than not) Yes Recognise as a provision on the balance sheet
Probable No (cannot be measured reliably) Disclose as a contingent liability
Possible (but not probable) N/A Disclose as a contingent liability
Remote N/A No disclosure required

The key distinction is between “probable” and “possible.” If the outflow is probable and can be reliably estimated, it is a provision, not a contingent liability.

Common Examples

Example Nature of Contingency
Pending litigation A customer has issued proceedings claiming £200,000 in damages. The outcome depends on the court’s decision.
HMRC tax dispute HMRC has opened an enquiry into the company’s R&D tax credit claim. An additional tax charge may result.
Product warranty beyond provisions The company has provided for expected warranty claims but faces potential claims beyond the provision.
Guarantee given for a subsidiary The parent company has guaranteed a subsidiary’s bank loan. If the subsidiary defaults, the parent must pay.
Environmental remediation The company may be required to clean up contamination on a former industrial site depending on a regulatory decision.
Indemnity to a buyer On selling a business, the company gave indemnities covering potential tax liabilities.

Recognition Versus Disclosure

When to Recognise (Provision)

A provision is recognised on the balance sheet when all three conditions are met:

  1. The entity has a present obligation (legal or constructive) as a result of a past event
  2. It is probable that an outflow of economic benefits will be required to settle the obligation
  3. A reliable estimate can be made of the amount

When to Disclose (Contingent Liability)

A contingent liability is disclosed in the notes when either:

When Neither Recognition Nor Disclosure Is Required

If the possibility of an outflow is remote, no provision or disclosure is necessary.

Disclosure Requirements

When a contingent liability is disclosed, FRS 102 Section 21 requires the following information in the notes to the financial statements:

If it is not practicable to provide some of this information, that fact must be stated.

Example Note Disclosure

Contingent liabilities

The company is defending a claim brought by a former supplier alleging breach of contract. The claim is for £150,000 plus costs. Legal counsel has advised that the claim is unlikely to succeed, but the outcome cannot be determined with certainty. No provision has been made in these accounts.

Contingent Liabilities and the Balance Sheet

Contingent liabilities do not appear on the balance sheet. They are off-balance-sheet items. However, they are important for understanding the company’s true financial position because they represent potential future claims on the company’s assets.

Users of financial statements – lenders, investors, and creditors – pay close attention to contingent liability disclosures because:

Contingent Liabilities Versus Provisions

Feature Provision Contingent Liability
Recognised on balance sheet Yes No
Probability of outflow Probable Possible (or probable but not measurable)
Included in liabilities Yes No
Effect on profit Charged to income statement when recognised No charge unless reclassified as provision
Location in accounts Balance sheet + notes Notes only

A contingent liability may become a provision if circumstances change and the outflow becomes probable and measurable. Equally, a provision may be released if the obligation is resolved without payment.

Contingent Liabilities in Group Accounts

In consolidated accounts, contingent liabilities require particular attention:

Contingent Liabilities and the Audit

The audit of contingent liabilities involves:

Auditors assess whether the disclosure is complete and whether any contingent liability should be reclassified as a provision.

Contingent Liabilities and Corporation Tax

A contingent liability is not recognised in the accounts and therefore has no direct corporation tax impact. Tax implications arise only when:

Managing Contingent Liabilities

Risk Assessment

Directors should maintain a register of contingent liabilities, reviewed at least quarterly, covering:

Field Purpose
Description Nature of the potential obligation
Estimated amount Best estimate of the financial exposure
Probability Assessment of likelihood (possible/probable/remote)
Trigger event What would cause the liability to crystallise
Mitigation Steps being taken to reduce the risk
Insurance Whether any loss would be recoverable

Reducing Exposure

Contingent Liabilities in Small and Micro Companies

Small companies filing under the Companies Act 2006 reduced disclosure requirements may provide less detail in their notes, but they are still required to disclose material contingent liabilities. Micro-entity accounts prepared under FRS 105 have a simplified approach: contingent liabilities are disclosed unless the possibility of outflow is remote.

Contingent Assets

FRS 102 also addresses contingent assets, which are the mirror image:

Feature Contingent Liability Contingent Asset
Nature Possible obligation Possible inflow
Recognition Never recognised (until probable and measurable, then provision) Never recognised (until virtually certain, then it is no longer contingent)
Disclosure Required if possible Required if probable

Contingent assets are disclosed only when an inflow of economic benefits is probable. They are never recognised on the balance sheet unless the inflow is virtually certain. For a detailed treatment, see the guide to contingent assets.
