Some Historical Facts About The Big 4 Accounting Firms

The Big 4 accounting firms were formerly known as the big 8, which included (1) Arthur Andersen, (2) Arthur Young & Co., (3) Coopers & Lybrand, (4) Ernst & Whinney, (5) Deloitte, Haskins & Sells, (6) KPMG, (7) Touche Ross, and (8) Price Waterhouse. The elite four was formed with a series of mergers and dissolutions.

The Big 8 was reduced to the Big 6 in 1989 after two mergers. Deloitte, Haskins & Sells merged with Touche Ross to form Deloitte Touche, while Ernst & Whinney merged with Arthur Young to form Ernst & Young. Price Waterhouse then merged with Coopers & Lybrand in 1998 to establish PricewaterhouseCoopers or PwC. It whittled the group down to the Big 5.

Due to Arthur Andersen's role in the world-shocking Enron crisis, the five were reduced by one in 2002. Since then, the four largest existing accounting firms have been referred to as the big 4.
