Ron Dennis initially owned all of McLaren after buying out the original shareholders after Bruce McLaren's death. In 1983 he offered Mansour Ojjeh the chance to purchase 50% of the team, with McLaren becoming a joint venture with Ojjeh's TAG Group. In 2000, after supplying engines to the team through its Mercedes subsidiary for 5 years, DaimlerChrysler AG (now Daimler AG ) exercised an option to buy 40% of the TAG McLaren Group. Dennis and Ojjeh each retained a 30% share.
