Bangalore: Michael Dell and his investing firms are shelling out $750 million in cash towards the $24.4 billion purchase of Dell, the largest private equity-backed buyout since the financial crisis. And on Wednesday, an individual shareholder filed the first lawsuit, in Delaware, attempting to stop the buyout, reports Reuters.

Michael Dell is to contribute $500 million of his own cash, and remaining $250 million will be contributed by MSDC management- an affiliate of his investment vehicle, MSD Capital, according to a company filing on Wednesday. He also struck a deal this week with Microsoft and Silver Lake, who will partner him in Dell buyout.

Dell also said that it is targeting the repatriation of $7.4 billion of cash now parked abroad to help finance the deal. That may dismay some shareholders, as a hefty tax is usually levied on cash brought back from overseas.
