Auditing firms compromised independence by selling consulting advice to audit clients

Evidence

Another notable casualty of Enron’s downfall was the venerable Arthur Andersen accounting firm. The founder adhered to high accounting standards and to the ethos that their accountants are responsible to investors, not to corporate governance. The firm went awry through conflicting interest between their auditing responsibilities and consulting fees for advising Enron on, among other matters, how to capitalize on loopholes. — Albert Bandura, Moral Disengagement, 1447
