On June 30, 2006, Kirk Kerkorian, whose Tracinda Corporation is the third-largest shareholder of General Motors, proposed a global alliance between GM and the Renault-Nissan group. With Nissan's domestic sales sagging, Carlos Ghosn, the CEO of both Renault and Nissan expressed interest in possibly acquiring a stake in GM. GM held an emergency board meeting to examine Kerkorian's proposal; GM's board reaffirmed its support for CEO Rick Wagoner, and GM's turnaround plans. On July 14, 2006, after a meeting with Carlos Ghosn, Rick Wagoner decided to study the matter for 90 days, including non-alliance forming ventures.
