Oslo-listed WW ASA booked a gain of $55m in the final quarter of the year to push its 2014 bottom line to $166m.

Bjorn Kristian Roed of Danske Bank says adjusted earnings per share of $0.21 were in line with expectations of $0.19 per share after extracting "messy" net financials that included currency exchange headwinds.

Adjusted operating figures lagged forecasts with a gain of $63m missing the $70m consensus.
