Dutch sports carmaker Spyker, which bought Sweden's Saab in January from US auto giant General Motors, has notified the Amsterdam stock market operator that it has more liabilities than assets.

"NYSE Euronext has been informed today by Spyker Cars NV about a negative shareholders' equity position," the NYSE Euronext stock exchange said in a statement Wednesday.

The Dutch carmaker now must issue a statement within five days detailing its financial situation, Reuters said.

Spyker Cars, which has never made a profit, paid about 400 million dollars for Saab, of which about 75 million dollars was in cash and the rest in shares.

Spyker management has been in contact with NYSE Euronext, the statement said, adding that the stock exchange will not impose any listing measures on the carmaker while it was compliant with the exchange's regulations.

The company will report its first half results, which include the Saab Automobile acquisition for the first time, on Friday.

Chinese automaker Geely, which recently month bought the Volvo brand from Ford, said Wednesday that its first-half sales soared 55 percent on the back of booming demand in the world's largest car market.
