The US Public Company Accounting Oversight Board (PCAOB) has
published a list of more than 400 non-US companies listed on US
capital markets whose auditors cannot be inspected by the PCAOB due
to legal obstacles.

The Sarbanes-Oxley Act requires firms that audit companies
listed in the US to be registered with and inspected by the PCAOB,
an audit watchdog.

But the EC, China and Switzerland have refused to let the PCAOB
inspect firms based in their jurisdictions.

The PCAOB said it has published the list in case US investors
have been relying on the work of audit firms without realising
those firms are not being inspected by the PCAOB.

The board said it continues to work towards eliminating
inspection barriers in these jurisdictions.
