The Big Four

According to Wikipedia: in the late 20th century there was (were?) a Big Eight. The eight were Arthur Andersen, Coopers & Lybrand, Deloitte Haskins and Sells, Ernst & Whinney, Peat Marwick Mitchell, Price Waterhouse, Touche Ross, and Arthur Young. They were gradually reduced, by mergers and the collapse of Andersen in 2002, to four.

Wikipedia reports that in 2011, the Big Four acted as auditors to 99% of the companies in the UK's FTSE 100 Index, and 96% of the companies in the FTSE 250 Index. Such a high level of industry concentration has caused concern, and a desire among some in the investment community for the Big Four to be broken up. As of 2018, they were still waiting.
