International Accounting Standards

International Accounting Standards are the rules that set out how companies in many countries must measure and present their financial results, so that accounts prepared in different places can be compared.

The older standards are called IAS and newer ones are called IFRS, and together they form the reporting framework used by listed companies across most of Europe, Asia, Africa and Australasia.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

Before common standards existed, the same business could report very different profits depending on the country it reported in, which made cross-border investment a guessing game. A shared rulebook means an investor comparing a German engineering group with an Australian one is comparing figures built on the same measurement rules.

The framework is principles-based rather than a long list of prescriptive rules. Standards describe the economic substance a company must reflect, such as whether it genuinely controls an asset, and then require management to apply judgement and disclose the judgements they made.

In practical business terms, the standards decide things that move reported profit substantially. They govern when revenue can be recognised, which development costs may be capitalised as an asset rather than expensed, how leases appear on the balance sheet, and how goodwill from an acquisition is tested for impairment.

The most commonly discussed difference in this area is with US generally accepted accounting principles, which remain a separate framework. Companies listed in more than one market sometimes present a reconciliation, and finance teams working across both need to understand where the two treatments diverge.

Adoption is a national decision rather than an automatic one. Countries choose to require, permit or prohibit the standards, and many apply a simplified version for smaller private companies so that a family business is not forced to produce disclosures designed for multinationals.

In practice

Real-world examples.

1

Example

A UK-listed retailer moves its store leases onto the balance sheet under the leasing standard, adding $340,000,000 of right-of-use assets and a matching liability. Reported operating profit rises because rent is replaced by depreciation and interest, and the finance team spends a quarter explaining that nothing about the actual cash rent has changed.

2

Example

A software company applies the revenue standard and concludes that a three-year support contract must be recognised evenly rather than at signing. Sales bookings look unchanged, but reported revenue in the first year falls by roughly two thirds of the contract value.

3

Example

An Australian mining group acquires a competitor and recognises $80,000,000 of goodwill. Each year it must test that goodwill for impairment rather than amortise it, and a fall in commodity prices triggers a $12,000,000 write-down in year three.

Formula

Calculation

Year-one profit impact of capitalising development costs = Total spend - (Non-qualifying spend + Amortisation charge for the year) A medical device firm spends $3,000,000 on a development project. Under the capitalisation criteria, $2,400,000 qualifies as an intangible asset and the remaining $3,000,000 - $2,400,000 = $600,000 is research that must be expensed. The capitalised amount is amortised over a six-year useful life, giving an annual charge of $2,400,000 / 6 = $400,000. Year-one cost in the income statement is $600,000 + $400,000 = $1,000,000, compared with $3,000,000 if everything were expensed, a difference in reported pre-tax profit of $3,000,000 - $1,000,000 = $2,000,000.

Case study

Seen in the real world.

Vantor Diagnostics is an invented company used here as an illustrative example. It was a private business preparing for a stock market listing, which meant restating three years of accounts from local rules onto international standards.

Three changes did most of the damage to the story it had been telling investors. Equipment supplied to hospitals under long-term contracts had to be recognised over the contract life rather than on delivery, which moved $4,500,000 of revenue out of the most recent year. A $2,400,000 development project failed the capitalisation criteria and had to be expensed. Property held at a revalued amount was measured differently, changing the depreciation charge.

Restated profit for the latest year fell from $9,200,000 to $5,600,000, a reduction of $3,600,000. The listing went ahead at a lower valuation, and the chief executive later said the restatement should have been done two years earlier. The illustrative lesson is that accounting standards do not change the cash a business generates, but they very much change the numbers investors price.

Watch out

Common mistakes.

  • Assuming the standards change the underlying economics of a business, when they change only how and when those economics are reported.
  • Using IAS and IFRS as if they were rival frameworks, when they are simply older and newer standards within the same rulebook.
  • Believing that international standards are used everywhere, when several major economies including the United States apply their own framework.

Questions

People also ask.

Who writes these standards?

An independent international standard-setting board, whose proposals go through public consultation before being issued.

Do small private companies have to apply them?

Usually not in full, since many countries offer a simplified standard for smaller entities with far fewer disclosures.

Why do two companies applying the same standard report differently?

Because the framework is principles-based and relies on management judgement, which is why the judgements themselves must be disclosed.
