Citic Pacific chairman Larry Yung Chi-kin's resignation this week has turned the spotlight on other Yung family members at the company who may be removed to restore investor confidence.
Market observers speculated that Mr Yung's three children - Carl Yung Ming-jie, Frances Yung Ming-fong and Andy Yung Ming-tai - are likely to leave the company soon.
'I would be surprised if they stay,' shareholder activist David Webb said. 'They wouldn't have worked there if not for their father. If the son [Carl] stays on the board, it would look like he is acting as a proxy of his father.'
Mr Yung's daughter, Frances, was demoted and received a pay cut on October 21 last year. A day earlier, Citic Pacific revealed it had entered into huge leveraged foreign-exchange contracts on which it booked a loss of HK$15.89 billion.
Soon afterwards, the Securities and Futures Commission and Hong Kong Exchanges and Clearing began investigations into the deals.
Citic Pacific was criticised for waiting six weeks after the board learned of the money-losing contracts before publicly disclosing them, leaving shareholders in the dark and potentially creating opportunities for insider dealings.
