Accounting

The Public Company Accounting Oversight Board (PCAOB) is a US nonprofit created by Sarbanes-Oxley Act in 2002 to oversee audits of public companies. Funded by fees from issuers and registered firms. PCAOB inspects registered firms regularly, publishing inspection reports that identify audit deficiencies. Major firms (Big Four) face annual inspections; smaller firms every three years. Inspection findings drive audit quality improvements. PCAOB also sets auditing standards (replacing PCAOB Auditing Standards for AICPA's GAAS for public-company audits). Independent oversight has materially improved US audit quality since SOX, though periodic accounting failures still emerge.
