Nissan Motor Co. is likely to fall into the red in fiscal 2008 ending this March with a group operating loss of tens of billions of yen due to dwindling global auto sales and a stronger than expected appreciation of the yen, sources said Thursday.

Japan's third-largest automaker is also set to revise its group sales projection and its global vehicle sales target for the current business year downward, the sources said.

It would be the first consolidated operating loss posted by the automaker since current President Carlos Ghosn became chief operating officer in 1999, when Nissan formed an alliance with France's Renault SA to weather its financial difficulties.
