Exchange looks into Pioneer's Thai bank stake
The stock exchange is to examine whether Pioneer Industries International (Holdings) has breached listing rules by allegedly holding an illegal stake in a Thai bank and failing to declare it.
An exchange spokesman confirmed officials were examining the case but stopped short of saying it was a formal investigation.
He said the focus would be on whether price-sensitive information had been disseminated correctly.
The exchange was alerted to the case after a fractious general meeting on Tuesday in which Pioneer's 20 per cent shareholder, Regent Pacific, alleged Pioneer chairman Anthony Gaw had passed on price-sensitive information to Regent without informing other shareholders.
Regent cited a telephone conversation between Mr Gaw and Regent chairman Peter Everington in which it claimed Mr Gaw had said a 3.77 per cent stake in Bangkok Bank had not been approved by Thailand's investment board.
Regent immediately passed the information on to the exchange and the Securities and Futures Commission.
