What are the four primary activities of the PCAOB?

The Public Company Accounting Oversight Board (PCAOB) has four primary activities: establishing auditing and related professional practice standards, conducting inspections of registered public accounting firms, enforcing compliance with laws and regulations, and promoting transparency in financial reporting. These activities aim to enhance the reliability of financial statements and protect the interests of investors and the public. By overseeing the auditing profession, the PCAOB seeks to improve audit quality and promote confidence in the capital markets.
