Dell Inc's Founder Michael Dell has been advised by experts to raise his current offer of $24.4 billion for the sale of Dell to billionaire investor Carl Icahn.

Despite the advice of the special committee that was formed to assess the best option for Dell shareholders, Michael Dell was non-committal about the matter, sources said.

Billionaire investor, Carl Icahn has said that Michael Dell's current offer substantially undervalues the company's worth.

Institutional Shareholder Services or ISS is expected to share its view on the Michael Dell offer.

Market participants who are evaluating the transaction mentioned that Carl Icahn's move is a clear indication that he never aimed to broadly distribute the terms of the deal.

Southeastern Asset Management and Icahn are working closely in preparing an offer that would see to the shareholders tender which is worth 1.1 billion in shares which are priced at US $14 apiece. The amount rivals the offer of Silver Lake and Michael Dell's US $24.4 billion buyout offering, making each share worth $13.65 apiece.
