General Motors Co. (NYSE: GM) is the quintessential American company. Founded in 1897, the Detroit-based automotive company has weathered its fair share of boom and bust economic cycles. The company designs, manufactures, markets, and distributes new cars, trucks, and vehicle parts globally. GM additionally offers consumers automotive financial services. 

General Motors announced its Q3 2018 earnings on October 31, 2018. The global automaker reported $35.79 billion in revenues this quarter, compared to $33.6 billion over the same period last year. As of October 31, 2018, the company had a market capitalization of $51.22 billion.

Barra has since won a number of industry recognition awards, which include being named one of the 100 leading women in the North American auto industry. According to Barra's most recent filing with the SEC on February 15, 2018, she is the company's largest individual shareholder with 520,608 shares of General Motors.
