USA: enhancing auditor independence, objectivity and professional scepticism - PCAOB concept release published

The Public Company Accounting Oversight Board published a concept release earlier this week seeking views on how to enhance auditor independence, objectivity and professional scepticism: see here (pdf). The concept release returns to a question that has been asked before in the USA and in other jurisdictions: should there be mandatory audit firm rotation? Indeed, this is the principal focus of the concept release and of the interesting comments made by the PCAOB members in their statements published alongside the concept release and available here.
