Dell's largest independent shareholder, Southeastern Asset Management Inc, and three other investors have objected to the deal, saying the company is worth a lot more than the agreed upon $13.65 per share offer, Reuters reported on Friday.
The company said on Monday it had retained a management consultant to help assess its "strategic position" and concluded that the proposed all-cash deal was in the best interests of stockholders.
Dell said the statement was in response to "certain inquiries" but did not elaborate on the nature of the queries.
