The General Motors Company, also known as GM, is a United States-based automaker with its headquarters in Detroit, Michigan. The company manufactures cars and trucks in 34 countries, recently employed 244,500 people around the world, and sells and services vehicles in some 140 countries.^[2] By sales, GM ranked as the largest U.S. automaker and the world's second-largest for 2011,^[2] having the third-highest 2011 global revenues among automakers on the Fortune Global 500.^[3]

On June 1, 2011, the company filed for Chapter 11 bankruptcy, which was completed on July 10 of the same year. It was thereafter reorganized as a new entity that acquired the most valuable assets. GM became temporarily majority owned by the United States Treasury and, to a smaller extent, the Canada Development Investment Corporation^[4] and the government of Ontario,^[5][6][7] with the U.S. government investing US$57.6 billion under the Troubled Asset Relief Program.^[8]

The company focused its business on its four core North American brands: Chevrolet, Buick, GMC, and Cadillac. In Europe, following negotiation to sell a majority stake of German brand Opel, GM decided to retain full ownership.^[9] GM sold Saab Automobile to Spyker Cars NV, and closed its doors to the Hummer,^[10] Pontiac, and Saturn brands, the latter two dissolved under the former General Motors Corporation, now known as Motors Liquidation Company.
