Restructuring Noble Group has slimmed its loss for the second quarter on the backs of positive operating income and lower costs in some areas.

The William Randall-led company reported a $128.3m loss for the period versus a $1.75bn loss during the same period in 2017.

Revenue was $1.15bn, down from $1.58bn a year earlier, in great part due to "challenges" faced by Noble Group's five segments -- energy coal, LNG, metals, carbon steel and freight.
