The "Big Four" - additional information

The “Big Four” are the four global leaders in auditing and accounting. Deloitte, PricewaterhouseCoopers (PwC), Ernst and Young (EY) and KPMG together audit the majority of publicly traded companies worldwide. In 2017, Deloitte employed the largest number of people with more than 263,900. Founded in London in 1845 and headquartered in New York today, the company employed the largest share of its staff in the Americas, closely followed by Europe, the Middle East and Africa. Combined, the “Big Four” employed almost 945,000 people worldwide in 2017.

Deloitte was the largest auditing firm out of the four in terms of revenue in 2017, although PwC was now far behind - generating only 1.2 billion U.S. dollars less. While Deloitte made the largest share of its revenue in the Americas, London-based PwC’s revenue was the largest in Europe, the Middle East and Africa. All four of the leading auditing companies unsurprisingly made much of their revenue from their auditing, assurance and audit and enterprise risk services (AERS) sector. Among other things, the companies also specialize in tax and advisory or consulting services.
