A shareholder vote on Michael Dell's proposal to take the tech company private could be delayed if the deal is seen as being voted down, according to sources.
Shareholders who have already cast their votes in the $24.4 billion buyout have lined up against the Dell deal, sources said. But the vast majority of the votes have yet to be cast.
BlackRock is also reportedly planning to vote against the deal.
Dell faces an opposing bid from billionaire investor Carl Icahn. As Dell's second-largest shareholder, Icahn has been trying to get investors to vote down the deal by raising his competing offer.
