Helping companies apply IFRS | US GAAP in practice.

Most companies do not need IFRS or US GAAP.

Companies generally apply IFRS | US GAAP only if they have a good reason.

For EU domiciled companies, this is generally a listing on a regulated market link:

EU domiciled companies also often list securities on a US capital market. In this situation, many chose US GAAP to avoid the stigma associated with the SEC's IFRS exception for foreign private issuers (link: EU based companies may also have a US subsidiary that crosses IRS’s accrual accounting threshold (link: Occasionally, they will choose US GAAP for practical reasons (for example, if they employ a CPA who knows only GAAP).

Similarly, US domiciled companies have no reason to apply US GAAP unless they register with the SEC (link: or cross the IRS's threshold.

As US companies rarely list securities on foreign markets, they will only face an IFRS a requirement if they set up a subsidiary in a country that requires IFRS for non-listed companies. This is highly uncommon. More often, foreign subsidiaries will be required to maintain statutory accounts (a.k.a. national GAAP) for local reporting purposes. In these situations, US GAAP is only applied internally, to generate the reports the parent uses to prepare its consolidated financial statements.

This web site has been designed for companies that do because they:

  • are subsidiaries of listed companies
  • are preparing for a listing
  • would like to present their financial statements to a suitor or private investor
  • are required to apply IFRS or US GAAP by law or regulatiion
  • have decided to apply IFRS or US GAAP for some other good reason.

In the European Union (link: and many countries, companies are generally obligated to use statutory accounting standards (a.k.a. national GAAP).

An IFRS obligation generally (link: arises only when a company lists its securities on a capital market (though national requirements vary link:

In the United States, companies are free to use whatever accounting system they choose.

A US GAAP obligation generally arises only when a company registers with the SEC (link: or crosses the IRS's accrual accounting threshold (link:

Applying IFRS or US GAAP is not easy. Not only are the standards detailed and complex, but applying them requires judgment, which can take accounting professionals years of practice to develop.

And, that is only the first step. Applying IFRS or US GAAP also means dealing with auditors (on a regular basis), regulators (usually when things go awry) and courts (if the situation turns bad).

Consequently, most companies try to avoid IFRS and US GAAP until they are forced to use them.

For example, once one of our clients decided to apply IFRS for patriotic reasons.

As outlined in EC 1606/2002, IFRS must only be applied by consolidated entities that offer their securities on a regulated EU market. Member states are, however, allowed to extend this obligation to additional entities.

In most member states, this obligation is extended to banks, investments funds and other public interest entities. Some extend it further. One such state is The Slovak Republic.

In Slovakia, IFRS must be applied by entities that cross a revenue/asset/employee threshold.

The company in this example, crossed this threshold, but only it all of its international subsidiaries were included. It’s Slovak operations alone were well below.

We advised the company to simply relocate the consolidating entity to a different EU state that did not have this requirement. If it had done so, since it was a private company with no intention of listing on any market, it would have not had any IFRS obligation.

However, the company’s owners were proud a Slovak company had grown to become a world leader in its industry and elected to ignore this advice even though it meant additional responsibilities, a doubling of its accounting staff, a quintupling of its audit budget and a substantial bill for our services (the advice had been given at no charge).

Chart of Accounts

Practice begins with accounts.

This site publishes three charts of accounts: an IFRS specific COA, a US GAAP specific COA and a universal COA.

While all three are workable, the universal COA is most useful.

Policies & Procedures

Practice continues with policies and procedures.

To present these, this site prefers illustrative examples.

Some cover the basics, while others deal with more complicated issues.

Q&A forum

In practice, we all have questions.

While most visitors prefer to ask directly, some like to share their thoughts with everyone.



Occasionally, we all need help.

Since 1994, we have been helping companies train staff, set up reporting systems, reconcile various accounting standards, and deal with auditors, lawyers and regulators.

A chart of accounts is the foundation for practically every accounting system. Because, neither IFRS nor US GAAP define a chart of accounts, most searches lead to this site: link (google IFRS COA), link (google GAAP COA), link (wikipedia COA).

A discussion of why can be found on the COA page in the release notes.

Both IFRS and US GAAP focus on outlining principles and providing general guidance leaving it up to individual companies to translate this into specific policies and procedures. Various ways of illustrating how this is can be done are possible. This site prefers showing to over telling, which is why it focuses on illustrative examples.

Our company was established in the Czech Republic in 1994.

Its focus was US GAAP training for (the then newly established) subsidiaries of US companies.

Why was training so important?

While double entry accounting is double entry accounting, accounting standards are not accounting standards.

In the nineties, practically every European country had its own national accounting standard, a.k.a. national GAAP.

Even in the member states of the newly formed EU, national GAAPs varied considerably.

The European union has had an accounting directive(s) since its formation. However, as the directive gives member states a degree of flexibility, the resulting national legislation, while similar, is not identical.

Fast-forward 30 years. Most European countries still have a national GAAP.

While the recipe has been harmonized over the years, each retains its unique, national flavor.

For example, CZ GAAP still has no concept of a functional currency, requiring accounts to be kept in CZK even if a company's operations are predominantly in another currency (though this is expected to change by 2024).

This requirement can have a significant effect.

For example, one of our clients, a local subsidiary of an EU based company, experienced over 25% profitability swings in the early 2020s because its books were in CZK even though practically all its revenue, over 80% of its expenses and a large part of its debt was in EUR.

While these were “paper” differences, CZ GAAP serves as the basis for determining taxable income.

The result was that the subsidiary's parent had to fend off the subsidiary's creditors, who demanded additional guarantees because they were disquieted by the fluctuations in the subsidiary's after tax income.

In 1999, we added US GAAP advisory services.

Among the services we provide: CZ GAAP to IFRS | US GAAP reconciliation.

Not that it always yields the desired result.

For example, some time ago a Czech company decided to list on a US exchange.

After retaining an underwriter, the underwriter retained us to draft a report consistent with US GAAP.

As, unlike CZ GAAP, US GAAP distinguishes revenue/gains and expenses/losses, this was one the first adjustments.

After reviewing our preliminary results, the underwater decided against pursuing a listing.

Our first step was to eliminate the major differences and draft a preliminary report.

Up to then, the company had only applied CZ GAAP.

As CZ GAAP does not differentiate between revenue and gains, when a company sells (factors) its receivables, it recognizes revenue in the amount received and an expense in the receivables' book value.

Eliminating this difference caused almost half its previously reported revenue to disappear.

In and of itself, this would have been enough to dissuade a listing, but there was more.

  1. In addition to the revenue eliminated by applying US GAAP guidance to factored receivables, revenue further declined because, at the time, CZ GAAP required increases in inventory and self-manufactured asset costs to be capitalized with a credit to revenue.

  2. The company also did not recognize the full value of its lease assets nor any associated liabilities because CZ GAAP does not require leased assets to capitalized nor liabilities to be recognized. It only requires the capitalization of advance payments, which are amortized over the lease term.

  3. The company also did not recognize all of its leased assets because CZ GAAP does not require capitalization of operating leases even if their term is for substantially all the underlying asset's economic life.

  4. The company also did not recognize all its contingent liabilities because CZ GAAP does not generally require recognition of constructive obligations.

  5. The company also failed to distinguish between cost of sales, selling and administrative expenses as this distinction is not required by CZ GAAP.

  6. The company also capitalized both development and some research as well as employee training which, at the time, was consistent with CZ GAAP.

  7. The company also misapplied CZ GAAP guidance, for example by using tax depreciation periods for financial reporting purposes, but an examination of these issues was beyond the scope of our engagement.

A second step was not necessary.

After reviewing our preliminary report, the underwater decided to terminate its relationship with the company, which eventually wound up in receivership.

We continued to focus on US GAAP until the European Union decided to adopt IFRS (IAS) in 2002.

IFRS first appeared in 1970s, while US GAAP has been around since the 1930s.

The original IFRS, comprising 31 standards known as IAS, was published in 1975 (link:

It was not, however, widely used until 2005, when it was adopted by the European Union.

In the twentieth century, US GAAP was, by default, the world's only internationally accepted set of accounting principles.

As this did not sit well with the European Commission, in 2002 it decided to adopt IAS (link:, which later became IFRS.

"[In 1995, the Commission] recognized that the existing Directives as such were not suitable for the information needs of international capital markets and consequently large companies were increasingly being drawn to use U.S. Generally Accepted Accounting Practices (U.S. GAAP) in addition to their local Generally Accepted Accounting Practices (GAAP). This increased costs and sometimes resulted in confusion when comparisons were made to local GAAP. Furthermore, at a political level, the European Union had no influence on accounting standards adopted under U.S. GAAP, nor were the standards necessarily appropriate in an E.U. context.

"For these reasons, the Commission proposed that the European Union should place its full weight behind the international standards being developed by the International Accounting Standards Committee with the objective of establishing a set of standards that would be acceptable in capital markets world-wide."

Alexander Schaub, The Use of International Accounting Standards in the European Union, 25 Nw. J. Int'l L. & Bus. 609 (2004-2005)

Since then, IFRS has spread to most countries (link: and listed companies (link:

The IFRS standards adopted by the EU are available on its server.

Being quasi law, E-IFRS is available from the EU (link:

While the IFRS standards published by the IASB are not law, the IFRS standards republished in the European Union's Official Journal are.

As part of its agreement with the IFRS Foundation, the EU has the make IFRS standards it has adopted (European-IFRS) available for free both in the original and in translation.

IFRS does, however, continue to be the copyrighted property of the IFRS Foundation.

Obviously, the main advantage of accessing IFRS through the EU is that access is free.

But, as always, one gets what one pays for.

Firstly, the EU only publishes those standards it has adopted.

Secondly, it does not publish supplemental ("B") guidance, such as the Basis for Conclusions, nor does its server have any features that make researching IFRS easier.

Thus, anyone who is serious about IFRS uses the full, IASB version (link:

While not free, subscription has its benefits.

In addition to full access to all standards and all supplemental guidance, plus an archive of all published standards back to 1975, the site's robust search function is especially useful.

More importantly, subscribing bolsters the IASB's independence, helping it further its mission to make IFRS universally accepted throughout the world.

One reason the US SEC has not embraced IFRS is the influence the European political establishment exerts on IASB through its contributions (link:

Obviously, £200 per year will not pay for the IASB's independence, but every little bit helps.

The first US GAAP comprised 51 standards published over 20 years starting in 1939.

While primarily a US system, it has been used worldwide the 1950s.

US GAAP's development has been somewhat convoluted, so its full text has only been freely available since 2009.

The first GAAP comprised the Accounting Research Bulletins created by the American Institute of Certified Public Accountants' Committee on Accounting Procedure (link:

The CAP was followed by the Accounting Principles Board, which took over standard setting in 1959.

The APB's opinions were GAAP (link: until 1973, when the current standard setter, the Financial Accounting Standards Board, started issuing its Statements of Financial Accounting Standards.

Unfortunately, the AICPA also issued its own Statements of Position (link: and recognized even more guidance.

AICPA accounting interpretations

Practices widely recognized and prevalent either generally or in the industry

This structure could only be simplified after the Sarbanes-Oxley Act gave US Securities and Exchange Commission the ability to finally decide who has the right to create US GAAP.

Specifically, SOX.SEC. 108 (link: gives the SEC the right to designate a standard setter, not ratify individual standards.

This provision was included to prevent the SEC from cherry-picking standards, and so limits the influence of politics and politicians on standard setting.

Before then, it was the AICPA's Council that had this ability.

Unsurprisingly, the AICPA's Council used this ability to also recognize the AICPA's pronouncements (even though they were unavailable to the lay public)

In the past, the AICPA's pronouncements were generally available to AICPA members (family and friends) only.

Like the Liturgical Latin of old, this allowed AICPA members to project an aura of Ecclesiastical like infallibility that not only enhanced their prestige, but proved quite lucrative.

Obviously, in a post Enron/WorldCom world, such an approach to standard setting is no longer consistent with standards of transparency and objectivity to which the profession is now held.

As a result, the AICPA no longer sets accounting standards.

Instead, it concentrates on its roles as the guardian of the CPA exam and profession's chief lobbyist (link:

Unfortunately, some traditions die hard.

Like the AICPA of old, in addition to the FASB's standards, the SEC also recognizes its own pronouncements.

Fortunately, unlike the AIPCA of old, the SEC makes its pronouncements freely available on the ASC.

On July 1, 2009, the Accounting Standards Codification (link: made all US GAAP freely available to the general public.

Being quasi law, US GAAP's full text cannot be sold for profit.

While US GAAP standards are not law, their use is (indirectly) mandated by law.

This implies, like law, they must be available to those they govern at no charge.

Consequently, US GAAP is available for free, even though it is, in fact, a copyrighted work, and the property of the FAF.

However, the FASB is free to charge for premium services (such as search or copy functions).

While not absolutely necessary, these services make researching US GAAP much easier.

More importantly, they give those who use US GAAP the opportunity to directly support a standard setting process that is, without question, second to none.

As the use of IFRS grew, so did demand for IFRS training and advisory, until it comprised almost 80% of our business.

After the convergence project wound down and the SEC put IFRS adoption on hold, demand for US GAAP resurged.

Convergence reached its peak with IFRS 15 and ASC 606. It has been down hill ever since.

For example, even the best online summary link: fails to mention IFRS 16 and ASC 842 because, while similar, they are not converged.

However, like any rational couple with children, divorce does not mean the IASB and FASB did not stay friends.

For example, in 2022 the FASB decided to drop the idea of goodwill amortization more or less because the IASB made the same decision link: earlier.

While the SEC never explicitly said IFRS was out, this staff report link: left little doubt of its true intentions.

Today, our services are divided practically evenly between IFRS and US GAAP.
