The Hong Kong Society of Accountants supports the Hong Kong Exchanges and Clearing's (HKEx) proposal to de-list companies which attract disclaimers from their auditors, or adverse audit opinions. Society president Alvin Wong Tak-wai said: 'This would be a good move. It will enhance corporate governance in Hong Kong.' HKEx last month released a consultation paper proposing 11 criteria under which companies might be de-listed - including the controversial 'penny stock' suggestion that firms whose share prices traded under 50 HK cents for 30 consecutive days should be de-listed. The paper has been put on hold and will be reissued in October. Mr Wong said he hoped the new consultation paper would maintain the proposal to de-list firms with auditor disclaimers. According to the HKEx Web site, about 30 main-board listed companies attracted qualified audit opinions in their last financial statements.
