LONDON/PARIS (Reuters) - French car maker PSA Peugeot Citroen
Peugeot has net tangible assets worth 14 billion euros ($18.75 billion), according to Thomson Reuters data, and is expected to write down a significant part of it on Thursday, the people said.
Peugeot declined to comment. Traders said the company had called a surprise conference call for analysts on Thursday night.
Any such writedowns would come on top of operational headaches at Peugeot, which has been slammed by overcapacity and falling sales.
Analysts are forecasting a 1.52 billion euro full-year 2012 loss for Peugeot according to Thomson Reuters I/B/E/S. The firm is due to report results next Wednesday.
The auto unit of Peugeot, which last year was removed from France's benchmark Cac 40 index <.FCHI> because of its declining market capitalization, has been burning cash at a rate of roughly 200 million euros a month.
