KUALA LUMPUR (Reuters) - The Malaysian high court has granted AirAsia X Bhd a nine-month extension on a restraining order which prevents creditors from filing any legal proceedings against it, the airline said in a stock exchange filing. The filing on Thursday said the extension runs nine months from the day of the announcement. The court had granted a restraining order in March for three months, as the budget airline undergoes a restructuring of its 64.15 billion ringgit ($15.5 billion) debt. Earlier this month, AirAsia X shareholders approved its debt restructuring, allowing it to pursue a scheme it viewed as key to survival which includes a rights issue and a share subscription for new investors to raise 500 million ringgit.
