Carnival Corporation & plc, the world’s largest cruise shipping group, sais its 2016 earnings per share would be $0.08 lower than forecast in connection with the publication of the groups fourth quarter and full year 2015 results.

“On December 18, 2015, we said that we expected our adjusted diluted earnings per share for the 2016 first quarter to be in the range of $0.28 to $0.32 and 2016 full year to be in the range of $3.10 to $3.40,” the company said in statement.

“On January 26, 2016, updated only for the current assumptions in the table below, our adjusted diluted earnings per share for the 2016 full year would decrease by $0.08,” Carnival continued in its final 2015 result statement filed with the stock exchanges in London and New York.

The decrease was caused by foreign currency exchange rates, including both foreign currency translational and transactional impacts of $0.11 per share, partially offset by a $0.03 per share increase due to lower fuel prices, net of forecasted realized losses on fuel derivatives. “In addition, our adjusted diluted earnings per share for the 2016 first quarter would decrease by $0.02,” Carnival said.

The recent strengthening of the US dollar against many other currencies weakens the performance of those of the group’s companies that do not use the dollar.
