IAS 36, or International Accounting Standard 36, is a crucial rulebook that prevents companies from carrying their assets on the books at a value that's wildly optimistic and out of touch with reality. In simple terms, it forces a company to take a hard look at its belongings—from factories and machinery to brand names and goodwill—and ask, “Is this really worth what we say it is?” If an asset's recorded value (its carrying amount) is higher than the economic benefits it's expected to generate (its recoverable amount), the asset is considered “impaired.” IAS 36 dictates that the company must recognize an impairment loss by writing down the asset's value to its true recoverable amount. This isn't just an accounting exercise; it's a moment of truth that hits the income statement directly, reducing reported profits. As part of the broader IFRS framework used across Europe and many other parts of the world, IAS 36 ensures that a company's balance sheet presents a more faithful picture of its financial health.
Think of IAS 36 as a mandatory annual health check for a company's major assets. The process isn't random; it's triggered by specific clues or “indicators of impairment.”
Companies don't test every asset every year. They look for signs that an asset might have lost value. These can be:
For certain intangible assets like goodwill, an impairment test is mandatory at least once a year, regardless of whether there are any obvious signs of trouble.
If an indicator is present, the company must perform a formal impairment test.
An impairment charge is far more than just accounting jargon; it's a story about management, strategy, and value. For a value investor, understanding IAS 36 is like having a special lens to see through a company's narrative.
A large or recurring impairment charge is a significant red flag. It often signals that management made a poor capital allocation decision in the past, such as overpaying for an acquisition (leading to a goodwill impairment) or investing in a project that failed to deliver its promised returns. As Warren Buffett often notes, huge write-offs are typically the consequence of foolish acquisitions made at the peak of a business cycle. An impairment is management’s quiet admission: “We messed up.”
Here's a fascinating twist in IAS 36. If the reasons for a previous impairment no longer exist and an asset's recoverable amount has increased, a company can reverse the impairment loss (with the major exception of goodwill). This reversal is recognized as income. For a savvy investor, this creates an opportunity. A company that was forced to take a big, painful write-down during a recession might be sitting on undervalued assets. If you believe the company's prospects are improving, you might be buying assets at a steep discount to their potential future (and re-appraised) value.
This potential for reversals is a crucial difference between IFRS and US GAAP (the accounting standards used in the United States). Under US GAAP, the reversal of an impairment loss is generally forbidden. Once an asset is written down, it stays down. This means an investor analyzing a European company under IFRS might spot recovery potential that simply doesn't exist from an accounting perspective for a similar American company.
