In case you missed it, the Public Company Accounting Oversight Board had its fifth birthday last week on April 25.

So to help celebrate, Sarah Johnson at CFO.com reviews its short life life by the numbers. She has come up with some good stats too. 4000 public company audits reviewed in just five years, 700 inspections of small and large firms, 17 enforcement actions against auditors and firms and 17 Deloitte & Touche clients that had audit deficiencies in their 2004 audits.
