Billionaire Elon Musk has lined up 19 new investors to help with his $44bn purchase of Twitter. The commitments, totalling 7.1bn, will allow Mr Musk to reduce his own risk in the deal which has been approved by Twitter’s board but not completed. Mr Musk, whose rank as the world’s richest person is tied to the value of his stake in Tesla, has said he plans to finance the purchase through a mix of loans, investments and cash. Will the investors be guaranteed the return on Investment ?
