The Big 4, sometimes written as the Big Four, are the four largest international accountancy and professional services firms, which handle the vast majority of audits for publicly traded companies as well as many private companies. The Big Four firms are shown below, with their latest publicly available data: Accountancy (profession)[1] or accounting (methodology) is the measurement, statement or provision of assurance about financial information primarily used by managers, investors, tax authorities and other decision makers to make resource allocation decisions within companies, organizations, and public agencies. ...

Legal structure

None of the Big Four accounting firms is a single firm. Each is a network of firms, owned and managed independently, which have entered into agreements with other member firms in the network to share a common name, brand and quality standards. Each network has established an entity to co-ordinate the activities of the network. In two cases (KPMG and Deloitte Touche Tomatsu), the co-ordinating entity is Swiss, and in two cases (PricewaterhouseCoopers and Ernst & Young) the co-ordinating entity is a UK limited company. Those entities do not themselves practise accountancy, and do not own or control the member firms. It has been suggested that this article or section be merged into Limited liability company. ...

In most cases each member firm practises in a single country, and is structured to comply with the regulatory environment in that country. However, in 2007 KPMG announced a merger of four member firms (in the United Kingdom, Germany, Switzerland and Liechtenstein) to form a single firm.

The figures in this article refer to the combined revenues of each network of firms.

2007 Performance Analysis

The Big Four accounting firms had a banner year in 2007 with double-digit revenue growth on the heels of strong performances in 2006 and 2005. KPMG had the highest annual growth rate among the firms with 17.4%, followed by Deloitte at 15.5%, Ernst and Young at 15% and PricewaterhouseCoopers bringing up the rear at 14.4%. Despite this relatively slower growth, PwC remains the world's largest accounting firm with 2007 revenues of $25.2 billion, ahead of Deloitte at $23.1 billion, E&Y at $21.1 billion with KPMG being relatively the smallest firm at $19.8 billion.

Combined, the Big Four firms had an astounding total revenue of $89.2 billion. If the firms were to continue this level of performance, the combined total would exceed a hundred billion dollars in 2008.

The depreciating US dollar in 2007 was also a key contributor to this performance, as all the Big Four firms report in US$ but earn much of their revenues in Europe and Asia, where local currencies appreciated strongly against the dollar. In terms of local currencies, growth was a little subdued. Combined Big Four revenues grew 11.7% from $77.1 billion in 2006 to $86.1 billion in 2007. Thus foreign exchange effects contributed a full 4% points or $3 billion to the combined firms revenue.

These spectacular growth patterns are seen usually in much smaller companies, and that huge $20 billion professional service companies are able to achieve double-digit back-to-back growth rates is testimony to their global reach and ability to capitalize on the need for financial services by all of the world’s economies. Big Four firms leveraged well global mega trends of stringent financial reporting (Sarbanes Oxley, internal audit), strong IPO listings (and subsequent audit work), complex M&A deals (due diligence, assurance), growing tax complexity, emerging economies, globalization, private equity buyouts, and risk management.

Service Line Performance

In terms of service lines, Advisory and Consulting services for all four firms combined grew the fastest at 21.7% from $18.0 billion to $21.9 billion. Ernst and Young reported a terrific 29% growth in this service line. All other firms grew close to 20% in 2007. The Tax service line services for all four firms combined grew at 18.4% from $17.6 billion to $20.8 billion. KPMG’s Tax service line (ironically) grew the fastest at 20%, and Deloitte grew the slowest at 16.5%.

Audit or Assurance service line grew at the slowest relative pace. For all four firms combined, revenues grew 12.9% from $42.1 billion to $47.5 billion. This service line is the largest contributor to revenue and was likely held back by the sheer size of the practice. Ernst and Young again was the winner in this category with a revenue growth of 16%. PwC’s Assurance service line grew only 10.2%, the slowest in this category, and the lowest growth rate among all service lines and across all firms.

Owing to its high growth the Advisory service line became a larger contributor of total revenues to the Big Four firms. For all Big Four firms combined, the share of the Advisory service line of the total revenue grew from 23.1% in 2006 to 24.3% in 2007. This share gain of 1.2% came at the expense of Tax and Audit. Advisory services now contribute almost one-quarter of Big Four firm revenues, though there is disparity among the firms. In Deloitte and Touche, Advisory and Deloitte Consulting were 31% of total revenues in 2007, and in KPMG Advisory Services were 32% of total revenues. For E&Y, Advisory services were only 12% of total revenues in 2007.

Tax service line also marginally improved its contribution share. For all Big Four firms combined, the share of the Tax service line of the total revenue grew from 22.6% in 2006 to 22.9% in 2007.

Audit, owing to its slower growth, lost a lot of its contribution to the total. For all Big Four firms combined, the share of the Audit service line of the total revenue actually dropped from 54.3% to 52.8%, a share decrease of 1.5%. If such growth patterns were to continue in the service lines, Audit could well drop to less than 50% of total revenues in just a couple of years. Already in KPMG and Deloitte, Audit is less than 50% of total revenues.

Geographical Performance

As in previous years, the Big Four firms reported the strongest growth in Asia, helped by underlying strength in China, India and Southeast Asia. Europe turned in surprisingly good numbers while the mature market of the Americas had the slowest growth rate.

While Asia remains the smallest geographical segment, it grew by 22.2% from 2006 to 2007. Ernst and Young’s Asia segment grew by a spectacular 27%. Even Deloitte, with the slowest growth among the firms reported a 17.2% growth rate. Owing to its high growth rate, Asia’s share of total revenues for all the firms improved by 1% from 12% in 2006 to 13% in 2007, at the expense of the Americas.

Many firms reported more than 30% annual growth in the BRIC (Brazil, Russia, India and China) economies, reflecting the strong economic momentum in these countries.

Europe is the largest region by far for all the firms. On a combined basis, Europe had strong growth of 19.2% from $34.7 billion in 2006 to $41.4 billion in 2007. KPMG grew by 20.9% in Europe, while the slowest grower Deloitte reported a 12.6% growth rate. The combined Big Four European revenues in 2007 was $41.4 billion, a full 46% of the total combined revenue and increasing from 45% in 2006. For KPMG, Europe is already 54% of total revenues, contributing to more than half its total revenues. Surprisingly, the European region in 2007 raced ahead of Americas on a combined basis, widening its lead to almost $5 billion. By contrast, in 2006, combined European revenues was only $1.4 billion more than the Americas.

For all the Big Four firms the Americas grew the slowest and also lost its leading share in terms of revenues. On a combined basis, Americas had only moderate growth of 10.3% from $33.3 billion in 2006 to $36.7 billion in 2007. Deloitte grew by 11.9% in Americas, while the slowest grower PwC did not even make the 10% mark, reporting only a 9.1% growth rate. The combined Big Four American revenues fell a full 2% points from 43% of the total combined revenue in 2006 to 41%. KPMG, which is heavily Europe-based, only produced 33% of its total revenues from the Americas. Even the PwC behemoth had only 38% of total revenues from Americas.

On a combined basis, the Americas are nearly $5 billion in revenue behind the biggest region, Europe, and this gap appears to be widening rather quickly. This geographic size and growth disparity, especially in the Americas, is sure to pose some interesting questions to the currently-US-centric Big Four firms about their future center-point and constitution of their top leadership.

Mergers and the Big Auditors

Since 1989, mergers and one major scandal involving Arthur Andersen have reduced the number of major accountancy firms from eight to four. The phrase mergers and acquisitions or M&A refers to the aspect of corporate finance strategy and management dealing with the merging and acquiring of different companies as well as assets. ...

Big 8 (until 1989)

The firms were called the Big 8 for most of the 20th century, reflecting the international dominance of the eight largest accountancy firms:

1. Arthur Andersen
2. Arthur Young & Company
3. Coopers & Lybrand
4. Ernst & Whinney (until 1979 Ernst & Ernst in the US and Whinney Murray in the UK)
5. Deloitte Haskins & Sells (until 1978 Haskins & Sells in the US and Deloitte Plender Griffiths in the UK)
6. Peat Marwick Mitchell, later Peat Marwick
7. Price Waterhouse
8. Touche Ross

Most of the Big 8 originated in alliances formed between British and US accountancy firms in the 19th or early 20th centuries. Price Waterhouse was a UK firm which opened a US office in 1890 and subsequently established a separate US partnership. The UK and US Peat Marwick Mitchell firms adopted a common name in 1925. Other firms used separate names for domestic business, and did not adopt common names until much later: Touche Ross in 1960, Arthur Young (at first Arthur Young, McLelland Moores) in 1968, Coopers & Lybrand in 1973, Deloitte Haskins & Sells in 1978 and Ernst & Whinney in 1979.^[2] For the U.S. Supreme Court case commonly known as Arthur Andersen, see Arthur Andersen LLP v. ... Ernst & Young is one of the largest professional services firms in the world, and a Big 4 accountancy firm, along with PricewaterhouseCoopers (PwC), Deloitte Touche Tohmatsu (Deloitte) and KPMG. // History The firm as we know it today is the result of a series of mergers of ancestor organizations. ... Coopers & Lybrand was an accounting firm which merged in 1998 with Price Waterhouse to form PricewaterhouseCoopers. ... Ernst & Young is one of the largest professional services firms in the world, and one of the Big Four auditors, along with PricewaterhouseCoopers (PwC), Deloitte Touche Tohmatsu (Deloitte) and KPMG. Ernst & Young is a global organization consisting of many member firms. ... Deloitte Haskins & Sells was a predecessor firm of Coopers and Lybrand UK (now PricewaterhouseCoopers) and Deloitte Touche Tohmatsu elsewhere in the world. ... KPMG is one of the largest professional services firms in the world. ... ... Deloitte Touche Tohmatsu (branded as Deloitte) is the second largest professional services firm in the world after PricewaterhouseCoopers and one of the Big Four auditors, a group of the largest international public accountancy firms. ...

The firms' initial international expansion was driven by the needs of British and US based multinationals for worldwide service. They expanded by forming local partnerships or by forming alliances with local firms. multinational corporation (or transnational corporation) (MNC/TNC) is a corporation or enterprise that manages production establishments or delivers services in at least two countries. ...

Arthur Andersen had a different history. The firm originated in the United States, and expanded internationally by establishing its own offices in other markets, including the United Kingdom.

In the 1980s the Big 8, each now with global branding, adopted modern marketing and grew rapidly. They merged with many smaller firms. One of the largest of these mergers was in 1987, when Peat Marwick merged with the KMG Group to become KPMG Peat Marwick, later known simply as KPMG. KPMG is one of the largest professional services firms in the world. ...

Big 6 (1989-1998)

Competition among these public accountancy firms intensified and the Big 8 became the Big 6 in 1989 when Ernst & Whinney merged with Arthur Young to form Ernst & Young in June, and Deloitte, Haskins & Sells merged with Touche Ross to form Deloitte & Touche in August. Ernst & Young is one of the largest professional services firms in the world, and one of the Big Four auditors, along with PricewaterhouseCoopers (PwC), Deloitte Touche Tohmatsu (Deloitte) and KPMG. Ernst & Young is a global organization consisting of many member firms. ... Deloitte Touche Tohmatsu is one of the Big Four auditors. ...

Confusingly, in the United Kingdom the local firm of Deloitte, Haskins & Sells merged instead with Coopers & Lybrand. For some years after the merger, the merged firm was called Coopers & Lybrand Deloitte and the local firm of Touche Ross kept its original name. In the mid 1990s however, both UK firms changed their names to match those of their respective international organizations.

Big 5 (1998-2002)

The Big 6 became the Big 5 in July 1998 when Price Waterhouse merged with Coopers & Lybrand to form PricewaterhouseCoopers. A former PwC office building (Southwark Towers) in London, England. ...

Big 4 (2002-)

The Enron collapse and ensuing investigation prompted scrutiny of their financial reporting, which was audited by Arthur Andersen, which eventually was indicted for obstruction of justice for shredding documents related to the audit in the 2001 Enron scandal. The resulting conviction, since overturned, still effectively meant the end for Arthur Andersen. Most of its country practices around the world have sold to members of what is now the Big Four, notably Ernst & Young globally and Deloitte & Touche in the UK. Enron Creditors Recovery Corporation (formerly Enron Corporation) (former NYSE ticker symbol: ENE) was an American energy company based in Houston, Texas. ... For the U.S. Supreme Court case commonly known as Arthur Andersen, see Arthur Andersen LLP v. ... Timeline of the Enron scandal: // CFO Andrew Fastow begins committing crimes by creating off-book entities for personal enrichment [1] Andrew Fastow creates Chewco in an effort to hide debt and inflate profits but Chewco doesnt meet requirements to keep it off Enrons balance sheet. ... Ernst & Young is one of the largest professional services firms in the world, and one of the Big Four auditors, along with PricewaterhouseCoopers (PwC), Deloitte Touche Tohmatsu (Deloitte) and KPMG. Ernst & Young is a global organization consisting of many member firms. ... Deloitte Touche Tohmatsu is one of the Big Four auditors. ...

Big 4 are sometimes referred as "Final Four"[5] due to widely held perception that authority is unlikely to allow further concentration of accounting industry and that the fifth biggest accounting firm, BDO International, is unlikely to grow to comparable size of Big 4. Another widely held belief is that, if something similar to Enron/Arthur-Andersen occurs, the authority is unlikely to punish the remaining Big 4 in a manner which destroy the firm itself like U.S. authority did with Arthur Andersen.

2002 also saw the passage of the Sarbanes-Oxley Act into law, providing strict compliance rules to both businesses and the auditors. Before the signing ceremony of the Sarbanes-Oxley Act, President George W. Bush meets with Senator Paul Sarbanes, Secretary of Labor Elaine Chao and other dignitaries in the Blue Room at the White House July 30, 2002. ...
