South Korea's Daewoo Shipbuilding & Marine Engineering is set to graduate this week from a creditors' debt rescheduling plan, a move that will shore up credit ratings for the world's second-largest shipbuilder. An early end to the plan was widely anticipated as the shipyard has shown a dramatic turnaround with a flood of new orders, creditors said on Monday. "The company's earnings performance has improved dramatically," said Yang Moon-suk, a spokesman for Korea Development Bank, the main creditor for the shipbuilder. "Working-level officials of creditors have already agreed that Daewoo Shipbuilding is now able to stand on its own and an announcement is due by Friday," he added.
