Arthur Andersen
Arthur Andersen LLP, based in Chicago, is a holding company and formerly one of the "Big Five" accounting firms among PricewaterhouseCoopers, Deloitte Touche Tohmatsu, Ernst & Young and KPMG, providing auditing, tax, and consulting services to large corporations. In 2002, the firm voluntarily surrendered its licenses to practice as Certified Public Accountants in the United States after being found guilty of criminal charges relating to the firm's handling of the auditing of Enron, an energy corporation based in Texas, which had filed for bankruptcy in 2001.
One of the few revenue-generating assets that the Andersen firm still has is Q Center, a conference and training facility outside of Chicago.
The former consultancy and outsourcing arm of the firm, now known as Accenture, which had separated from the accountancy side in 1987 and renamed themselves after splitting from Andersen Worldwide in 2000, continues to operate and has become one of the largest multinational corporations in the world.
