Deloitte
Deloitte is a British multinational professional services network based in London, United Kingdom. It is the largest professional services network in the world by revenue and number of employees, and is one of the Big Four accounting firms, along with EY, KPMG, and PwC. The Deloitte network is composed of member firms of Deloitte Touche Tohmatsu Limited (/dəˈlɔɪt ˈtuːʃ toʊˈmɑːtsuː/ də-LOYT TOOSH toh-MAHT-soo) a private company limited by guarantee incorporated in England and Wales.
The firm was founded by accountant William Welch Deloitte in London, England in 1845 and expanded into the United States in 1890. It merged with Haskins & Sells to form Deloitte Haskins & Sells in 1972 and with Touche Ross in the US to form Deloitte & Touche in 1989. In 1993, the international firm was renamed Deloitte Touche Tohmatsu, later abbreviated to Deloitte. In 2002, Arthur Andersen's practice in the UK as well as several of that firm's practices in Europe and North and South America agreed to merge with Deloitte. Subsequent acquisitions have included Monitor Group, a large strategy consulting business, in 2013.
Deloitte provides audit, consulting, financial advisory, risk, tax, and legal services with approximately 470,000 employees globally, and operates in over 150 countries. In FY 2024, the network earned revenues of US$67.2 billion in aggregate. The firm has sponsored a number of activities and events, including the 2012 Summer Olympics.
The firm suffered a major cyberattack in 2017, causing a breach in client confidentiality and publicizing a significant amount of employee information. Deloitte has also been subject to litigation regarding several of its audits.
In 1845, William Welch Deloitte opened an office in Basinghall Street in London, England. Deloitte was the first person to be appointed an independent auditor of a public company, namely the Great Western Railway. He went on to open an office in New York in 1880. The firm was based at No. 4 Lothbury in London from 1855 to 1905, when it moved to No. 54 London Wall Buildings.
In 1890, Deloitte opened a branch office on Wall Street headed by Edward Adams and P.D. Griffiths as branch managers. This was Deloitte's first overseas venture. Other branches were soon opened in Chicago and Buenos Aires. In 1898 P.D. Griffiths returned from New York and became a partner in the London office.
In 1896, Charles Waldo Haskins and Elijah Watt Sells formed Haskins & Sells in New York. It was later described as "the first major auditing firm to be established in the country by American rather than British accountants".
In 1898, George Touche established an office in London and then, in 1900, joined John Ballantine Niven in establishing the firm of Touche Niven in the Johnston Building at 30 Broad Street in New York.
