News Summary: Dell deal faces new stumbling blocks
BIDDING BATTLE: Two new suitors are making buyout offers for struggling personal computer maker Dell Inc. They want to scuttle an existing agreement to sell Dell to CEO Michael Dell and other investors led by Silver Lake Partners for $24.4 billion.
DEAL SWEETENERS: The alternative proposals submitted separately by billionaire investor Carl Icahn and buyout specialist Blackstone Group LP offer a higher price for some of Dell's outstanding stock.
PRIVATE VS. PUBLIC: Dell would end its 25-year history as a public company, if the deal with Michael Dell is completed. Its stock would still trade publicly under the other proposals.
