Tesla Inc founder Elon Musk is working with US firms Wachtell, Lipton, Rosen & Katz and Munger, Tolles & Olson to move forward his proposal to take the electric carmaker private, while Tesla’s board of directors has retained Wilson Sonsini Goodrich & Rosati and Latham & Watkins to evaluate the chief executive’s bid.

After facing a series of questions over possible funding sources for such an effort, Musk has signalled that he remains serious about pursuing the potential buyout, announcing via a Monday evening tweet that he is working with financial advisers from The Goldman Sachs Group Inc and private equity firm Silver Lake Partners, with Wachtell and Munger Tolles serving as outside legal advisers on the proposal.
