The Volvo Group (; legally Aktiebolaget Volvo, shortened to AB Volvo, stylized as VOLVO) is a Swedish multinational manufacturing corporation headquartered in Gothenburg. While its core activity is the production, distribution and sale of trucks, buses and construction equipment, Volvo also supplies marine and industrial drive systems and financial services. In 2016, it was the world's second-largest manufacturer of heavy-duty trucks with its subsidary Volvo Trucks. Automobile manufacturer Volvo Cars, also based in Gothenburg, was part of AB Volvo until 1999, when it was sold to the Ford Motor Company. Since 2010 Volvo Cars has been owned by the automotive company Geely Holding Group. Both AB Volvo and Volvo Cars share the Volvo logo and cooperate in running the Volvo Museum in Sweden. The corporation was first listed on the Stockholm Stock Exchange in 1935, and was on the NASDAQ indices from 1985 to 2007. Volvo was established in 1915 as a subsidiary of SKF, a ball bearing manufacturer; however both the Volvo Group and Volvo Cars regard the rollout of the company's first car series, the Volvo ÖV 4, on 14 April 1927, as their beginning. History Early years and international expansion The brand name Volvo was originally registered as a trademark in May 1911 with the intention to be used for a new series of SKF ball bearings. It means "I roll" in Latin, conjugated from "volvere". The idea was short-lived, and SKF decided to simply use its initials as the trademark for all its bearing products. In 1924, Assar Gabrielsson, an SKF sales manager, and Gustav Larson, a KTH educated engineer, decided to start construction of a Swedish car. They intended to build cars that could withstand the rigors of the country's rough roads and cold temperatures. AB Volvo began activities on 10 August 1926. After one year of preparations involving the production of ten prototypes, the firm was ready to commence the car-manufacturing business within the SKF group. The Volvo Group itself considers it started in 1927, when the first car, a Volvo ÖV 4, rolled off the production line at the factory in Hisingen, Gothenburg. Only 280 cars were built that year. The first truck, the "Series 1", debuted in January 1928, as an immediate success and attracted attention outside the country. In 1930, Volvo sold 639 cars, and the export of trucks to Europe started soon after; the cars did not become well known
