Enron's auditor 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, Arthur 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 Arthur 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.
Enron hired numerous Certified Public Accountants (CPAs) as well as accountants who had worked on developing accounting rules with the Financial Accounting Standards Board (FASB). The accountants searched for new ways to save the company money, including capitalizing on loopholes found in Generally Accepted Accounting Principles (GAAP), the accounting industry's standards. One Enron accountant revealed "We tried to aggressively use the literature [GAAP] to our advantage. All the rules create all these opportunities. We got to where we did because we exploited that weakness.
