Accounting Firm — Big Four
The biggest of the Big Four is Deloitte, the U.S. member firm of U.K.-based Deloitte Touche Tohmatsu Ltd., with domestic revenue of $16.1 billion in 2015. Just over half of that came from audit and enterprise risk, advisory, and tax services, while the consulting business is the fastest-growing segment. The giant firm employs more than 58,000 professionals in this country, staffing more than 100 offices in 91 cities. One of Fortune’s 100 Best Companies to Work For and winner of numerous awards, such as the International Accounting Bulletin’s “Audit Innovation of the Year” prize in 2015, Deloitte now adds CFO’s Readers’ Choice Award to the list.
