General Motors (GM), one of the world's largest auto manufacturers, makes cars and trucks, with well known brands such as Buick, Cadillac, Chevrolet, and GMC. GM also builds cars through its GM Daewoo, Opel, Vauxhall, and Holden units. The company operates through five business segments: GM North America, GM Europe, GM International Operations, and GM South America. Financing activities are primarily conducted by General Motors Financial Company. The current iteration of GM traces its roots to mid-2009, when the former GM was split into two companies after it emerged from Chapter 11 bankruptcy protection: General Motors and Motors Liquidation (the name for leftover assets).
