The auditing profession has confronted significant changes over the last several decades. The major CPA firms, considered capable of auditing the world’s largest publicly traded companies, have undergone consolidation or liquidation (Arthur Andersen). Major corporate scandals have rocked the financial markets.

Is this a sustainable activity – paying for audits that do not uncover the major frauds that are occurring? Why do the major auditing firms fail to find the frauds even though the auditing standards require the auditing firms to actively search for fraud? What would happen if the model for auditing required the insurance companies to hire the auditors before insurance for company, officer and director liability could be issued?

The issue of independence is so fundamental to an effective auditing system that brings accountability to stakeholders (creditors, shareholders, future shareholders, taxpayers, the public).

Unfortunately, independence is sacrificed far too often in the auditing profession.
