Southeastern Asset Management, whose 8.5 percent stake makes it the largest independent shareholder in computer maker Dell, has retained veteran dealmakers from Greenberg Traurig and Shearman & Sterling to advise on its opposition to the company’s proposed $24.4 billion leveraged buyout.

A source familiar with the matter told The Am Law Daily that Memphis–based Southeastern has hired Shearman senior partner and M&A maestro Creighton Condon and Dennis Block, senior chairman of Greenberg’s corporate and M&A practice, to advise on its objections to the Dell deal. (The New York Times‘s DealBook noted Block’s involvement in the matter earlier this week.)
