A deal to sell a majority stake in Adam Opel GmbH to a group led by Magna International Inc., may be signed by General Motors Co. this week. 

The parties are as of now working through outstanding details, and the contracts are being completed. GM Chief Executive Officer Fritz Henderson explained, "The U.S. carmaker, which won't receive cash, agreed on Sept. 10 to sell 55 percent of Ruesselsheim, Germany-based Opel to Magna and Russian partner OAO Sberbank." 

As per the predictions, these documents might be signed this week. 

From quite some time now, Germany has been pushing for Opel's sale to Aurora, Ontario-based Magna since May, and it is also the one which is supporting the 5 billion-euro ($7.4 billion) transaction. A sum of 4.5 billion euros was offered by Chancellor Angela Merkel's government in loan guarantees, with the aim of financing the reorganization of the unprofitable division, which employs about half of its 50,000-strong workforce in Germany. 

It has appeared that a sum of 500 million euros is to be invested in Opel by Magna, Canada's biggest car-parts manufacturer, and Moscow-based Sberbank. 

It has appeared that the sale of Opel constitutes part of Detroit-based GM's effort to slash its lineup to restore earnings. Opel also produces vehicles under the Vauxhall brand in the U.K.
