General Motors has agreed to sell loss-making Saab to Swedish Koenigsegg Group, according to Swedish state television.

The deal between General Motors and Koenigsegg Group has been signed and will be officially announced on Tuesday, Swedish state television SVT said on Monday.

A sources close to the deal said a share transfer agreement already has been signed, allowing Koenigsegg Group to purchase GM's shares in the ailing car maker.

The sum is still undisclosed. Daily Dagens Nyheter wrote that GM and Koenigsegg had agreed on a "very low" price for Saab.

"The price tag is non-existent but GM has a deal that grants them revenues as well if Koenigsegg manages to get Saab back on its feet," Dagens Nyheter quoted a source close to Saab as saying.

The deal also contains a sizeable number of knotty agreements about transfer of technology and service between GM and Saab.

However, the consortium led by the Koenigsegg Group had yet to secure financing. It also awaits response from the Swedish government about a state guarantee for a 4.3 billion kronor ($593 million) loan from the European Investment Bank. The loan would form a vital part of the financing for the acquisition.

Augie K Fabela, chairman of Koenigsegg Group, said in an interview with business daily Dagens Industri that the group is still 3 billion kronor short in financing. 

Saab is currently under creditor protection. The reorganisation will be allowed to continue until August 20 and the working process to get the Saab deal finished is in an extremely intensive stage.

Saab Automobile made a operation loss last year of 4,148 million kronor ($377 million, $553 million). That is an increase of 90 percent from a loss of 2.194 million kronor a year ago.

Both Saab Automobiles and GM refused to comment on the report on Monday evening.
