Major investors offer to buy a big stake in Uber -- at a 30% discount

A group of investors led by Softbank have put in a bid to buy $6B worth of Uber stock -- at a valuation of $48B, 30% lower than the company's valuation at its last finance round, which was followed by string of ghastly scandals including the removal of its founder, Travis Kalanick, from the CEO's office. The company has 20 days to respond.
