Following the Auditing Practices Board's intention to update its standards on auditor ethics at the beginning of last month, it has today issued exposure drafts open for public comment on International Standards on Auditing issued by the International Auditing and Assurance Standards Board. These standards, once finalised, will replace the existing ISAs and International Standard on Quality Control as of 15 December 2010. The APB highlighted last year that more work was needed with regards to auditor ethics, with particular focus on the rotation period for audit engagement partners, the rewards given to key partners involved in audits, the selling of non-audit services such as advisory or consulting work by those involved in the audit of their client, and the independence of the audit team from the company's internal auditors. Today it has issued the exposure drafts of 33 clarified ISAs, the ISQC, and a revised Statement of the Scope and Authority of APB Pronouncements, which are open for comment until 22 July. A consultation paper has also been issued which highlights respondents' views on whether the APB should adopt these audit changes and, if so, when. Richard Fleck, chairman of the APB, said: 'I am pleased that the results of the October 2008 consultation support APB's view that the new clarified ISAs are more rigorous and clearer than the existing ISAs and accordingly should be implemented in the UK and Ireland as soon as is practicable.'
