Thai chipmaker Alphatec Electronics Plc after creditors turned down a rescue plan put forward by an investment company owned by Swedish telecommunication firm Ericsson AB and American International Group. The investment companies offered to put in $40m for a five-year restructuring plan in return for an 80% stake in the equity (CI No 3,551), but at a meeting on Monday, creditors led by Rung Thai Bank turned down the scheme claiming it was an attempt to write down debts rather than rehabilitate the company.
