Enron's accounting firm, Arthur Andersen, was accused of applying reckless standards in its audits because of a conflict of interest over the significant consulting fees generated by Enron. During 2000, Andersen earned $25 million in audit fees and $27 million in consulting fees (this amount accounted for roughly 27% of the audit fees of public clients for Andersen's Houston office). The auditor's methods were questioned as either being completed solely to receive its annual fees or for its lack of expertise in properly reviewing Enron's revenue recognition, special entities, derivatives, and other accounting practices.
