Michael Dell may contribute equity financing of $500 million to $1 billion in addition to his approximately 16 percent stake in Dell, worth about $3.6 billion, to push his ownership above 50 percent and have majority control, Bloomberg said.

Michael Dell's partners - private equity firm Silver Lake and giant software company Microsoft Corp - would contribute $1 billion to $2 billion each toward an equity check of $8 billion to $9 billion, Bloomberg said.

Details of the equity financing were still being finalized while making sure Dell has explored all possible alternative options, including a sale to other buyers, Bloomberg said.

Representatives of Dell, Silver Lake and Microsoft did not immediately respond to requests for a comment.

Dell has formed a special committee of its independent directors and has hired Evercore Partners Inc to assess whether the company is getting the best deal for shareholders and not one that is just in the best interest of Michael Dell, people familiar with the matter have previously told Reuters.
