Tokyo - Nissan plans to expand job cuts to over 10 000 to help turn around its business, a person with direct knowledge of the matter said on Wednesday, as profit continues to plunge while the carmaker grapples with management upheaval.

The global plan includes the 4800 job cuts announced in May and will mostly be at factories overseas with low utilisation rates, the person said. It will be announced along with financial results on Thursday, said the person, who declined to be identified as the information was still private.

Nissan declined to comment on the job cuts. Its shares ended the day up nearly 1.0%.

Analysts expect Nissan to post one of its weakest quarterly performances since the 2008 global financial crisis when it announces its first-quarter earnings on Thursday.

On Wednesday, the Nikkei business daily reported the carmaker would report operating profit of "several billion yen" for the quarter, around a 90% drop from a year earlier. Analysts estimate a decline of 64%.

The job cuts, exceeding 7% of Nissan's 138 000-strong workforce, come as Nissan struggles to improve dismal profit margins in the United States, a key market where former Chairman Carlos Ghosn for years pushed to aggressively grow market share during his time as chief executive.

Years of heavy discounting to grow sales in the world's second-biggest car market have left Nissan with falling demand for the Altima sedan and other models, a cheapened brand image and low resale values, while the costs to offer high discounts have hit its bottom line.

The latest job cuts also highlight the extent of problems facing Chief Executive Hiroto Saikawa, who is also grappling with fractured relations with French alliance partner Renault SA following the arrest of their shared former chairman.

Ghosn has been charged with financial misconduct and denies wrongdoing.

Saikawa kept his job in a vote at an annual shareholders meeting last month, though he had to fight off a rare rebuke by top proxy advisory firms who urged shareholders not to reappoint him considering he was groomed for leadership by Ghosn.

In May, Nissan forecast a 28% plunge in annual operating profit, adding to a 45% fall in the previous year, putting the automaker on course for its weakest earnings in 11 years.

While addressing faltering performance, Saikawa also has to repair trust with Renault, which has deteriorated in past months as the French automaker sought more control within Nissan.

Renault owns 43% of the Japanese carmaker, which in turn holds a 15%, non-voting stake in its partner. Saikawa, who has sought more equal footing with Renault, last month said Nissan would postpone discussions on the alliance's future to prioritise performance.

The extended job cuts were first reported by Kyodo late on Tuesday.
