Talk about shutting the stable door after the horse has bolted. The looming insolvency of once-mighty commodities trader Noble Group Ltd. is an overdue reckoning for a company that has long sailed close to the wind, a Bloomberg View reported. More than that, though, it’s a black mark against the city-state where it’s been listed since 1997: Singapore. Noble has spent the past year squirming through an attempted restructuring to keep it from bankruptcy, hampered by its money-losing operating business and years of squandered trust.

Singaporean regulators investigating Noble Group Ltd. have focused their questions so far on the company’s use of mark-to-market accounting, according to people familiar with the matter. The struggling commodity trader was thrown into fresh crisis last week after Singapore announced a three-agency probe into Noble’s accounts just days before a marathon $3.5 billion debt restructuring was due to complete, Bloomberg News reported. On Sunday, Noble said it would delay the deadline for that deal to Dec.

Noble Group Ltd. extended the deadline for its marathon restructuring until Dec. 11 to address regulators’ concerns, a week after Singaporean authorities began an investigation into the embattled commodity trader’s finances, Bloomberg News reported. The company on Sunday moved the deadline for the $3.5 billion debt restructuring back by two weeks. Noble said that Singapore’s Securities Industry Council extended a key waiver to allow the deadline to be pushed back.

Singapore authorities are investigating Noble Group Ltd for suspected false and misleading statements, just days before the Singapore-listed company was to complete its $3.5 billion debt restructuring deal to prevent its collapse, Reuters reported. Noble, once Asia’s top commodity trader, has seen its market value all but wiped out from $6 billion in February 2015 after its accounting was questioned by Iceberg Research.
