Michael Dell has raised his offer to take Dell private by $0.10 per share, to about $24.7 billion, after the company was forced to delay a vote because stockholders seemed inclined to reject the bid. The new bid of $13.75 per share from Michael Dell and Silver Lake Partners prompted the company to adjourn the special stockholder meeting for a second time while a special committee of the board of directors evaluates the new bid. The meeting will be reconvened at 9 a.m. Central Time on August 2, the special committee said Wednesday.
