Imagine you run a car manufacturing company, and one of your models has been in the news because its brakes occasionally fail. You haven't been sued yet, but let's be honest-it's probably coming. Should your financial statements pretend everything is rosy? Or should they show that a storm might be brewing?
This is exactly what provisions are about. They're amounts you set aside in your financial statements for liabilities that are uncertain in timing or amount, but likely to happen. Think of them as financial umbrellas you carry when dark clouds gather, even if it hasn't started raining yet.
IAS 37 Provisions, Contingent Liabilities and Contingent Assets is the accounting standard that tells us when to recognise these "maybe" liabilities, when to just mention them in notes, and when to ignore them completely. It's all about being honest with investors and stakeholders about what might go wrong-without crying wolf every time there's a tiny risk.
Before diving deep, let's understand the three siblings in the IAS 37 family:
The key distinction? Recognition versus disclosure. Provisions make it onto the balance sheet. Contingent items stay in the notes-they're acknowledged but not counted yet.
According to IAS 37, a provision is a liability of uncertain timing or amount. But it's not just any uncertainty-it must meet three strict criteria before you can recognise it:
All three must be ticked off. Miss one? No provision for you.
The obligation must exist now, arising from a past event. This past event is called an obligating event-one that creates a legal or constructive obligation that leaves the entity with no realistic alternative to settling it.
Legal obligations are straightforward-they come from contracts, legislation, or other operations of law. If you sign a contract promising to restore a mining site after extraction, you have a legal obligation.
Constructive obligations are trickier. They arise when:
Real example: For years, a supermarket chain has had a policy of refunding customers who are dissatisfied with products, even without legal obligation. Customers expect this. At year-end, even though the supermarket doesn't know exactly who will return what, it has a constructive obligation to provide refunds and should recognise a provision.
Probable means "more likely than not" to occur. In practical terms, this means a probability greater than 50%. If there's only a 40% chance you'll have to pay, it's not probable-you have a contingent liability instead, not a provision.
This threshold matters enormously. It's the difference between recording a liability on your balance sheet (which affects your ratios, your borrowing capacity, your share price) and merely mentioning it in a note that many investors might skim over.
You must be able to estimate the amount reliably. Notice the word isn't "perfectly" or "exactly"-it's reliably. Provisions are estimates by nature. You're dealing with uncertainty, but that uncertainty must be quantifiable.
The standard acknowledges that in extremely rare cases, no reliable estimate can be made. In such cases, you can't recognise a provision-you disclose it as a contingent liability instead.
Once you've decided a provision is needed, you need to figure out how much to record. IAS 37 provides clear guidance:
The amount recognised should be the best estimate of the expenditure required to settle the present obligation at the end of the reporting period. This is the amount the entity would rationally pay to settle the obligation or to transfer it to a third party at that date.
Think of it as: "If someone offered to take this problem off your hands right now, what would you reasonably pay them?"
The estimation method depends on what you're dealing with:
A company sells 10,000 products with a one-year warranty. Based on past experience:
Expected value calculation:
\[ \text{Expected cost per unit} = (0.80 \times £0) + (0.15 \times £50) + (0.05 \times £200) \] \[ = £0 + £7.50 + £10 = £17.50 \]Total provision = 10,000 × £17.50 = £175,000
Notice we didn't just pick the "most likely" outcome (£0) for each individual product. When dealing with large populations, the expected value smooths out the uncertainty across all items.
When the effect of the time value of money is material, provisions should be discounted to their present value. This applies when:
The discount rate should be a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. It should not reflect risks already considered in estimating future cash flows.
A company operates a nuclear power station. It has a legal obligation to decommission the facility in 20 years. The estimated cost at that time is £50 million. The appropriate pre-tax discount rate is 5%.
Present value calculation:
\[ \text{Present Value} = \frac{\text{Future Value}}{(1 + r)^n} \] \[ = \frac{£50,000,000}{(1.05)^{20}} = \frac{£50,000,000}{2.6533} = £18,843,000 \]The company recognises a provision of approximately £18.84 million now, not £50 million. Each year, the provision will increase as the present value "unwinds"-this increase is recognised as a finance cost (sometimes called unwinding the discount).
The estimate should take into account risks and uncertainties. However, uncertainty doesn't justify creating excessive provisions or deliberately overstating liabilities (that would violate the principle of prudence/conservatism without becoming imprudent).
Future events that may affect the amount required to settle an obligation should be reflected in the provision where there is sufficient objective evidence that they will occur.
Example: A provision for environmental cleanup costs might consider new technology that will reduce costs, but only if there's objective evidence (not just hope) that this technology will be available and used.
This is where things get interesting. The obligating event is the trigger. Let's explore common scenarios:
Imagine your company announces it's closing a factory and laying off 500 workers. Do you immediately recognise a provision for redundancy costs?
Not necessarily. A restructuring is a programme planned and controlled by management that materially changes either the scope of a business or the manner in which it's conducted.
You can only recognise a restructuring provision when you have a constructive obligation, which requires:
Just having a board decision isn't enough. Just announcing vague "efficiency improvements" isn't enough. You need a detailed plan and to have raised valid expectations.
Include only direct expenditures arising from the restructuring, not costs associated with ongoing activities. This means:
The exclusion of future operating losses is crucial. Provisions aren't created for normal business activities, even if they're expected to be loss-making. If a factory will lose money until it closes, those future losses don't go into the provision. Only the direct costs of closing do.
An onerous contract is one in which the unavoidable costs of meeting the obligations exceed the economic benefits expected to be received. "Unavoidable costs" are the lower of the cost of fulfilling the contract and any compensation or penalties from failure to fulfill it.
When you have an onerous contract, recognise a provision for the present obligation under the contract.
Example: You've signed a three-year lease for £100,000 per year for a retail space. After one year, you decide to close that location permanently. You try to sublet it but can only find a tenant willing to pay £60,000 per year. The remaining two years will cost you £40,000 per year more than you'll receive.
You have an onerous contract. You should recognise a provision for the unavoidable net cost:
\[ \text{Provision} = 2 \text{ years} \times (£100,000 - £60,000) = £80,000 \](This would typically be discounted to present value if material.)
When you sell products with warranties, the obligating event is the sale. At the point of sale, you've created an obligation-even though you don't know which specific products will fail or when.
This is a classic case for using the expected value method across a large population, as we demonstrated earlier.
These often arise from legal requirements or constructive obligations to clean up contamination or restore sites.
The obligating event is the action that causes the damage or creates the legal obligation-often the extraction of resources or the operation of facilities.
Real-world example: BP's Deepwater Horizon oil spill in 2010 created massive environmental obligations. The obligating event was the spill itself. BP ultimately recognised provisions exceeding $60 billion for cleanup costs, fines, and compensation-one of the largest provisions in corporate history.
A contingent liability is either:
The critical distinctions:
There's one exception: if the possibility of outflow is remote, you don't even need to disclose a contingent liability.
For each class of contingent liability (unless the possibility of outflow is remote), disclose:
A contingent asset is a possible asset that arises from past events and whose existence will be confirmed only by the occurrence or non-occurrence of uncertain future events not wholly within the entity's control.
Examples include:
Contingent assets are never recognised on the balance sheet. This reflects the prudence principle-don't count income until it's virtually certain.
However, when the inflow of economic benefits is probable, disclose the contingent asset in the notes (with similar details as for contingent liabilities).
When the realisation becomes virtually certain, it's no longer contingent-it becomes a real asset (typically a receivable) and should be recognised.
Here's how to work through any scenario:
Understanding the accounting mechanics helps cement the concepts. Here's how provisions move through the books.
When you first recognise a provision:
Dr Expense (or relevant cost category) £XXX
Cr Provision £XXX
Example: Recognising a warranty provision of £175,000:
Dr Warranty Expense £175,000
Cr Warranty Provision £175,000
The expense hits the profit or loss statement (reducing profit), and the provision appears as a liability on the balance sheet.
When you actually incur the costs the provision was created for:
Dr Provision £XXX
Cr Cash/Payables £XXX
Example: During the year, warranty repairs costing £120,000 are performed:
Dr Warranty Provision £120,000
Cr Cash/Inventory/Payables £120,000
Notice: this does not go through the income statement again. You already recognised the expense when you created the provision. Now you're just settling the liability.
At each reporting date, review provisions and adjust to reflect the current best estimate.
If the estimate increases:
Dr Expense £XXX
Cr Provision £XXX
If the estimate decreases:
Dr Provision £XXX
Cr Income/Reduction in expense £XXX
For discounted provisions, the carrying amount increases each period as you get closer to the payment date. This is called unwinding the discount.
Dr Finance Cost £XXX
Cr Provision £XXX
Using our earlier decommissioning example where we recognised £18.84 million for a £50 million obligation in 20 years at 5%:
After year 1, the provision increases by £18.84m × 5% = £942,000
Dr Finance Cost £942,000
Cr Decommissioning Provision £942,000
After year 1, the provision stands at £18.84m + £0.942m = £19.782m. This continues each year until, by year 20, it reaches the full £50m needed.
When your company faces a lawsuit, the accounting treatment depends entirely on likelihood and measurability:
Lawyers often resist giving definitive probability assessments, which creates challenges. Management must make informed judgments based on all available evidence.
Real-world example: When Volkswagen's emissions scandal broke in 2015, the company initially recognised provisions of approximately €6.7 billion in September 2015. By December 2015, this increased to €16.2 billion as the scale became clearer. The provisions covered vehicle refits, legal costs, and fines-all meeting the criteria of present obligation, probable outflow, and reliable estimate (even though the exact amounts were uncertain).
Mining, oil and gas, and chemical companies face significant obligations to rehabilitate sites after operations cease.
The obligating event typically occurs when:
These provisions are usually:
Example scenario: A mining company begins operations in January 2024. The mine will operate for 15 years. Legal requirements mandate site restoration when operations cease. Estimated restoration cost: £30 million in 2039. Discount rate: 6%.
Present value in 2024:
\[ PV = \frac{£30,000,000}{(1.06)^{15}} = \frac{£30,000,000}{2.3966} = £12,518,000 \]The company recognises a provision of £12.518 million and typically capitalises this as part of the cost of the mine asset (rather than expensing immediately). The asset is then depreciated over the mine's life, and the provision is unwound each year through finance costs.
When a company discovers a product defect that requires recall, the obligating event is either:
Before announcement, even if the defect is known internally, there may be no constructive obligation if the company hasn't committed to a recall.
Once the recall is announced, recognise a provision for:
Sometimes when you have an obligation, a third party will reimburse some or all of the expenditure. Common examples:
When reimbursement is virtually certain to be received:
Example: A company recognises a £500,000 provision for legal settlement. Insurance will reimburse £300,000 (virtually certain).
Journal entries:
Dr Legal Expense £500,000
Cr Legal Provision £500,000
Dr Insurance Receivable £300,000
Cr Legal Expense £300,000
Net effect on profit: £500,000 - £300,000 = £200,000 expense
Balance sheet shows:
If the reimbursement is only probable but not virtually certain, disclose it as a contingent asset but don't recognise it.
Provisions aren't "set and forget." IAS 37 requires reviewing them at each reporting date and adjusting to the current best estimate.
Increases in provisions are recognised as expenses (unless capitalised as part of an asset, such as with decommissioning costs).
Decreases reverse previous expenses or create income.
Where a provision is no longer required (the obligation is cancelled or expires), reverse it entirely:
Dr Provision £XXX
Cr Income £XXX
IAS 37 has extensive disclosure requirements. For each class of provision, disclose:
This reconciliation (often presented as a table) helps users understand how provisions evolved during the year.

Each class would be accompanied by narrative explaining the nature, timing, and uncertainties.
It's important to know the boundaries. IAS 37 does not apply to:
So when you see pensions, deferred tax, or lease obligations, remember: different standards apply.
An executory contract is one where neither party has performed their obligations, or both have partially performed their obligations to an equal extent.
Example: You sign a contract to purchase £100,000 of inventory in three months. Until you receive the goods or pay, it's executory-equally unperformed on both sides.
Generally, executory contracts don't create provisions because the obligations are balanced. However, if the contract becomes onerous, IAS 37 kicks in and you recognise a provision for the unavoidable net loss.
IAS 37 embodies the prudence principle: recognise losses when probable, but don't recognise gains until virtually certain. This prevents over-optimistic reporting.
However, prudence must not become an excuse for creating "hidden reserves"-deliberately overstating provisions in good years to smooth profits by releasing them in bad years. This is earnings manipulation and violates the faithful representation principle.
The best estimate should be exactly that: your best judgment of the actual obligation, not a "rainy day fund" or a profit-smoothing tool.
Tobacco companies face massive litigation over health impacts. For decades, these companies disclosed contingent liabilities for lawsuits but often didn't recognise provisions, arguing outcomes weren't probable or reliably measurable.
As judgments accumulated and settlement patterns emerged, some companies began recognising substantial provisions. Philip Morris USA, for instance, recognised provisions for certain state settlements once the terms became sufficiently certain.
This illustrates the judgment required: at what point does a "possible" liability become "probable"? When do you have enough information to estimate reliably? Different companies, faced with similar lawsuits, sometimes reached different conclusions-all within the framework of IAS 37, but reflecting different interpretations of the facts.
