Tanayong Plc

Tanayong Plc's auditor has issued a disclaimer of opinion on the company's financial statement for the quarter ended March 31.

The Stock Exchange of Thailand said the filing, which represent the company's financial status and operating results for the quarter, may not adequately and/or properly reflect the actual position of the company.

The SET is asking that the company's shareholders and investors carefully scrutinise the auditor's report on its financial statements.

The trading suspension on Tanayong shares is still in effect because the company has yet to prepare a rehabilitation plan.
