Yaohan International Holdings, whose former directors are being investigated by the Commercial Crime Bureau, is to be wound up after failing to settle $500 million in outstanding debts. The company said creditor Hidomi Holdings, which is also its wholly owned subsidiary, filed a winding up petition against Yaohan yesterday. The court appointed two partners of accounting firm KPMG Peat Marwick as provisional liquidators and will hold a hearing on the liquidation on September 16. The provisional liquidators will take charge of Yaohan's assets. Yaohan's limited assets on hand include a 24.47 per cent stake in indoor amusement chain Whimsy Entertainment. Yaohan closed at 3.9 cents on Monday, its last trading day.
