(15)The Public Company Accounting Oversight Board of the United States of America intends to evaluate further the auditor oversight systems of the Member States before deciding to rely on the oversight performed by their competent authorities. Therefore, the mechanism of cooperation between the competent authorities of the Member States and the Public Company Accounting Oversight Board of the United States of America and the Securities and Exchange Commission of the United States of America should be reviewed to assess the progress made towards reaching mutual reliance on each other’s oversight systems. For those reasons, this Decision should be applicable for a limited period of time.
