Wallenius Wilhelmsen Logistics' (WWL) bottom line and operating results improved for the third quarter, thanks to a better cargo and trade mix and synergies realised from last spring's merger.

The Oslo-listed ro-ro operator, formed in April by merging Wilh Wilhelmsen and Wallenius Lines' Wallroll, posted net income of $55m, up from $40m in earnings a year ago.

"We are pleased to see the improved results in the third quarter which is normally weaker than the second quarter," said chief executive Craig Jasienski, whose company saw a $49m loss in the second quarter due to a one-time $267m merger charge.
